1. Abstract

There is lot of buzz in Information Technology industry for cloud computing. What does any

of the IT Company does? Either it builds a software product or provides services for those

products by deploying and maintaining. Who uses these products and services? All types oforganizations like Universities, Healthcare, Government, Manufacturing, Telecom, IT etc..Some 10 years ago, if an organization (small, medium or large) wanted to use Software, they hadto buy Hardware and Software and install/deploy them in their premise, which was very costly.Apart from initial huge investment, there was regular maintenance cost associated. Then severalIT companies came up with idea of cloud computing, which is similar to electricity connection toour homes. One does not worry, how electricity is generated, distributed and maintained, Whatan end user does is uses how much they want and pays the bill every month depending upon theirusage.

Cloud computing is the delivery of computing and storage capacity as a service to a community

of end-recipients From WikipediaThere are many kinds of IT resources like Hardware (CPU cycles, Memory, I/O) Storage,Operating System, Database, Middleware, Applications (Mail Server, CRM, ERP, HCM,Business Intelligence, Social Networking etc..) which can be provided on rent.Roughly, Some organizations, especially non-IT organizations need Applications with fewcustomization to work for them and they do not built software, Some Organizations need to buildtheir own custom software application and they just need a development platform/environmentlike Middleware (Application server, Identity Management etc..) and Database and fewcompanies need to Use the Hardware, Operating system or Storage directly so that they can usetheir own Middleware and custom Applications. Depending upon the type of resource on rent,

cloud computing offerings are classified as SAAS (Software as a Service), PAAS (Platform as a

service) and IAAS (Infrastructure as a Service).

Now for these cloud offerings, there are plenty (100+) of companies who provides one or moretypes of these services, and its difficult to decide which vendor to choose for which cloud based

service. This term paper is intended to collect information from various resources on what isbeing offered by established players in this field like Amazon, Salesforce, Microsoft, Googleetc.. Along with new cloud providers like Oracle, RackSpace, GoGrid etc..Also, In this term paper, there is very detailed comparison made between key provider in IAASand PAAS domain namely Amazon AWS, Google App Engine, Microsoft Windows Azure,Salesforce's Force.com, Rackspace and GoGrid.

2. Introduction

Cloud computing is a model for enabling convenient , on-demand network access to a sharedpool of configurable computing resources (e.g., networks, servers, storage, applications, and

services) that can be rapidly provisioned and released with minimal management effort orservice provider interaction. By NISTThis definition from the National Institute of Standards (NIST) describes five essentialcharacteristics, three service models and four deployment models.

Five Essential Characteristics

On-demand self service Users areable to provision, monitor and managecomputing resources as needed withoutthe help of human administratorsBroad network access Computing

services are delivered over standardnetworks andheterogeneous devicesRapid elasticityIT resources are ableto scale out and in quickly and on an asneeded basisResource pooling IT resources areshared across multiple applications andtenants in a non-dedicated manner

Measured serviceIT resource utilization is tracked for each application and tenant, typicallyfor public cloud billing or private cloud chargeback

Three Service Models

Software as a Service (SaaS) Applications delivered as a service to end-users typicallythrough a Web browser. There are hundreds of SaaS service offerings available today, rangingfrom horizontal enterprise applications to specialized applications for specific industries, andalso consumer applications such as Web-based email. Oracle CRM On DemandPlatform as a Service (PaaS)An application development and deployment platformdelivered as a service to developers who use the platform to build, deploy and manage SaaSapplications. The platform typically includes databases, middleware and development tools, all

delivered as a service via the Internet. PaaS offerings are often specific to a programminglanguage or APIs, such as Java or Python. A virtualized and clustered grid computingarchitecture is often the basis for PaaS offerings, because grid provides the necessary elasticscalability and resource pooling.Infrastructure as a Service (IaaS) Compute servers, storage, and networking hardwaredelivered as a service. This infrastructure hardware is often virtualized, so virtualization,

management and operating system software are also part of IaaS as well. Examples of IaaSinclude: Amazon CloudFormation (and underlying services such as EC2), Rackspace Cloud,Google Compute Engine, and Right Scale.

Four Deployment Models

Private Clouds For exclusiveuse by a single organization andtypically controlled, managed andhosted in private data centers. Thehosting and operation of privateclouds may also be outsourced to athird party service provider, but aprivate cloud remains for theexclusive use of one organization.Public Clouds For use bymultiple organizations (tenants) ona shared basis and hosted and

managed by a third party service provider.Community CloudsFor use by a group of related organizations who wish to make use of acommon cloud computing environment. For example, a community might consist of thedifferent branches of the military, all the universities in a given region, or all the suppliers to alarge manufacturer.Hybrid CloudsWhen a single organization adopts both private and public clouds for asingle application in order to take advantage of the benefits of both. For example, anorganization might run the steady-state workload of an application on a private cloud, but when aspike in workload occurs, such as at the end of the financial quarter or during the holiday season,they can burst out to use computing capacity from a public cloud, then return those resources to

the public pool when they are no longer needed.There are 100s of companies which offer cloud computing based applications or services.

Here I have considered top 12 enterprise level companies, which provides paid services to othercompanies (This does not include free social applications which are for general users like Gmail,Facebook, Twitter etc, though they are SAAS). This term paper provides technical details of theoffering made by them.1. Google2. Microsoft3. Amazon4. Salesforce5. IBM

3. Detailed Case Studies

3.1. Google

Google has mainly three cloud based offerings:Google App Engine (PAAS)Google Compute Engine (IAAS)Google Cloud Storage (IAAS)

3.1.1 Google App Engine

Google App Engine is a web application hosting service. By web application, we mean an

application or service accessed over the Web, usually with a web browser: storefronts withshopping carts, social networking sites, multi-player games, mobile applications, surveyapplications, project management, collaboration, publishing, and all of the other things were

discovering are good uses for the Web. App Engine can serve traditional website content too,such as documents and images, but the environment is especially designed for real-time dynamicapplications.


7/45

App Engine can be described as three parts:The runtime environment, The datastore, and the Services.

3.1.1.1 The Runtime Environment

An App Engine application responds to web requests. A web request begins when a client,typically a users web browser, contacts the application with an HTTP request, such as to fetch a

web page at a URL. When App Engine receives the request, it identifies the application from thedomain name of the address, either an .appspot.com subdomain (provided for free with everyapp) or a subdomain of a custom domain name you have registered and set up with Google Apps.App Engine selects a server from many possible servers to handle the request, making itsselection based on which server is most likely to provide a fast response. It then calls theapplication with the content of the HTTP request, receives the response data from theapplication, and returns the response to the client.From the applications perspective, the runtime environment springs into existence when the

request handler begins, and disappears when it ends. App Engine provides at least two methodsfor storing data that persists between requests, but these mechanisms live outside of the runtimeenvironment. By not retaining state in the runtime environment between requestsor at least, bynot expecting that state will be retained between requestsApp Engine can distribute trafficamong as many servers as it needs to give every request the same treatment, regardless of howmuch traffic it is handling at one time.

3.1.1.2 The Datastore

Most useful web applications need to store information during the handling of a request forretrieval during a later request. A typical arrangement for a small website involves a single

database server for the entire site, and one or more web servers that connect to the database tostore or retrieve data. Using a single central database server makes it easy to have one canonicalrepresentation of the data, so multiple users accessing multiple web servers all see the same andmost recent information. But a central server is difficult to scale once it reaches its capacity forsimultaneous connections.

By far the most popular kind of data storage system for web applications in the past decade hasbeen the relational database, with tables of rows and columns arranged for space efficiency andconcision, and with indexes and raw computing power for performing queries, especially joinqueries that can treat multiple related records as a queryable unit.

Other kinds of data storage systems include hierarchical datastores (filesystems, XML databases)and object databases. Each kind of database has pros and cons, and which type is best suited foran application depends on the nature of the applications data and how it is accessed. And eachkind of database has its own techniques for growing past the first server.

Google App Engines database system most closely resembles an object database. It


8/45


8

is not a join-query relational database, and if you come from the world of relational-database-backed web applications, this will probably require changing the way you think about yourapplications data. As with the runtime environment, the design of the App Engine datastore is

an abstraction that allows App Engine to handle the details of distributing and scaling theapplication, so your code can focus on other things.Entities and Properties

3.1.1.3 The Services

The datastores relationship with the runtime environment is that of a service: the applicationuses an API to access a separate system that manages all of its own scaling needs separately fromthe runtime environment. Google App Engine includes several other self-scaling services usefulfor web applications.

The memory cache (or memcache) service is a short-term key-value storage service. Its mainadvantage over the datastore is that it is fast, much faster than the datastore for simple storageand retrieval. The memcache stores values in memory instead of on disk for faster access. It isdistributed like the datastore, so every request sees the same set of keys and values. However, itis not persistent like the datastore: if a server goes down, such as during a power failure, memoryis erased. It also has a more limited sense of atomicity and transactionality than the datastore. Asthe name implies, the memcache service is best used as a cache for the results of frequentlyperformed queries or calculations. The application checks for a cached value, and if the valueisnt there, it performs the query or calculation and stores the value in the cache for future use.

App Engine applications can send messages using the Mail service. Messages can be sent on

behalf of the application or on behalf of the user who made the request that is sending the email(if the message is from the user). Many web applications use email to notify users, confirm useractions, and validate contact information. An application can also receive email messages. If anapp is configured to receive email, a message sent to the apps address is routed to the Mail

service, which delivers the message to the app in the form of an HTTP request to a requesthandler.

App Engine applications can send and receive instant messages to and from chat services thatsupport the XMPP protocol, including Google Talk. An app sends an XMPP chat message bycalling the XMPP service. As with incoming email, when someone sends a message to the appsaddress, the XMPP service delivers it to the app by calling a request handler.

The image processing service can do lightweight transformations of image data, such as formaking thumbnail images of uploaded photos. The image processing tasks are performed usingthe same infrastructure Google uses to process images with some of its other products, so theresults come back quickly. We wont be covering the image service API in this book because

Googles official documentation says everything there is to say about this easy-to-use service.

Google Compute Engine provides Linux virtual machines. One can spin up two VMs or 10,000VMs. What this means is that developers and businesses can grab a vast amount of processingpower and apply it to almost any task they want. Google hasnt just set up some new machinesand tossed on some hypervisor software that runs virtual machines. Like App Engine before it,Compute Engine runs atop the unified software platform that spans Googles roughly 40 data

centers worldwide.

3.1.3 Google Cloud Storage

Google Cloud Storage is a RESTful service for storing and accessing your data on Google'sinfrastructure. The service combines the performance and scalability of Google's cloud withadvanced security and sharing capabilities.Highlights include:

3.2.2 Windows Azure

Windows Azure is the Platform-as-a-Service offering (PaaS) from Microsoft. Like other cloudservices it provides the following features:

Compute Storage Connectivity Management

You can use this platform in many different ways. For instance, you can use Windows Azure tobuild a web application that runs and stores its data in Microsoft datacenters. You can useWindows Azure just to store data, with the applications that use this data running on-premises(that is, outside the public cloud). You can use Windows Azure to create virtual machines fordevelopment and test or to run SharePoint and other applications. You can use Windows Azureto build massively scalable applications with lots and lots of users. Because the platform offers awide range of services, all of these things-and more-are possible. Following are important

features of Windows Azure :1. Always up. Always on : Windows Azure delivers a 99.95% monthlySLAand enables you tobuild and run highly available applications without focusing on the infrastructure. It providesautomatic OS and service patching, built in network load balancing and resiliency to hardwarefailure. It supports a deployment model that enables you to upgrade your application withoutdowntime.2. Open: Windows Azure enables you to use any language, framework, or tool to buildapplications. Features and services are exposed using open REST protocols. The Windows Azureclient libraries are available for multiple programming languages, and are released under an opensource license and hosted on GitHub.3. Unlimited servers. Unlimited storage: Windows Azure enables you to easily scale your

applications to any size. It is a fully automated self-service platform that allows you to provisionresources within minutes. Elastically grow or shrink your resource usage based on your needs.You only pay for the resources your application uses. Windows Azure is available in multipledatacenters around the world, enabling you to deploy your applications close to your customers.4. Powerful Capabilities: Windows Azure delivers a flexible cloud platform that can satisfy anyapplication need. It enables you to reliably host and scale out your application code withincompute roles. You can store data using relational SQL databases, NoSQL table stores, andunstructured blob stores, and optionally use Hadoop and business intelligence services to data-mine it.

The Components of Windows Azure:

Figure : Windows Azure provides Internet-accessible application services running in

Microsoft datacenters.

Execution Models

One of the most basic things a cloud platform does is execute applications. Windows Azureprovides three options for doing this, as Figure 2 shows.

Each of these three approaches-Virtual Machines, Web Sites, and Cloud Services-can be usedseparately. You can also combinethem to create an application thatuses two or more of these optionstogether.Data Management

Applications need data, and differentkinds of applications need different


14/45


14

kinds of data. Because of this, Windows Azure provides several different ways to store andmanage data. It has the ability to run SQL Server or another DBMS in a VM created withWindows Azure Virtual Machines. (It's important to realize that this option isn't limited torelational systems; you're also free to run NoSQL technologies such as MongoDB andCassandra.) Windows Azure provides three data management options that are largely managedfor you. Figure 3 shows the choices.

Networking

Windows Azure runs today in severaldatacenters spread across the UnitedStates, Europe, and Asia. When you runan application or store data, you canselect one or more of these datacentersto use. You can also connect to thesedatacenters in various ways:

You can use Windows AzureVirtual Network to connect your

own on-premises local network to a defined set of Windows Azure VMs. You can use Windows Azure Connect to link one or more on-premises Windows servers

to a specific Windows Azure application. If your Windows Azure application is running in multiple datacenters, you can use

Windows Azure Traffic Manager to route requests from users intelligently acrossinstances of the application.

Business Analytics

Analyzing data is a fundamental part of how businesses use information technology. A cloud

platform provides a pool of on-demand, pay-per-use resources, which makes it a goodfoundation for this kind of computing. Accordingly, Windows Azure provides two options forbusiness analytics namely SQL Reporting and Hadoop MapReduceMessaging

No matter what it's doing, code frequently needs to interact with other code. In some situations,all that's needed is basic queued messaging. In other cases, more complex interactions arerequired. Windows Azure provides a few different ways to solve these problems. Figure 6illustrates the choices.Queues

Queuing is a simple idea: One application places a message in a queue, and that message iseventually read by another application. If your application needs just this straightforward service,

Windows Azure Queues might be the best choice.Service Bus

Whether they run in the cloud, in your data center, on a mobile device, or somewhere else,applications need to interact. The goal of Windows Azure Service Bus is to let applicationsrunning pretty much anywhere exchange data.


15/45


15

Unlike Windows Azure Queues, for example, Service Bus provides a publish-and-subscribemechanism. An application can send messages to a topic, while other applications can createsubscriptions to this topic. This allows one-to-many communication among a set of applications,letting the same message be read by multiple recipients. And queuing isn't the only option:Service Bus also allows direct communication through its relay service, providing a secure wayto interact through firewalls.Applications that communicate through Service Bus might be Windows Azure applications orsoftware running on some other cloud platform. They can also be applications running outsidethe cloud, however. For example, think of an airline that implements reservation services incomputers inside its own datacenter. The airline needs to expose these services to many clients,including check-in kiosks in airports, reservation agent terminals, and maybe even customers'phones. It might use Service Bus to do this, creating loosely coupled interactions among thevarious applications.Caching

Applications tend to access the same data over and over. One way to improve performance is tokeep a copy of that data closer to the application, minimizing the time needed to retrieve it.Windows Azure provides two different services for doing this: in-memory caching of data usedby Windows Azure applications and a content delivery network (CDN) that caches blob data ondisk closer to its users.Identity

Working with identity is part of most applications. For example, knowing who a user is lets anapplication decide how it should interact with that user. To help you do this, Microsoft providesWindows Azure Active Directory.Like most directory services, Windows Azure Active Directory stores information about usersand the organizations they belong to. It lets users log in, then supplies them with tokens they canpresent to applications to prove their identity. It also allows synchronizing user information with

Windows Server Active Directory running on premises in your local network. While themechanisms and data formats used by Windows Azure Active Directory arent identical with

those used in Windows Server Active Directory, the functions it performs are quite similar.High-Performance Computing

One of the most attractive ways to use a cloud platform is for high-performance computing(HPC), The essence of HPC is executing code on many machines at the same time. On WindowsAzure, this means running many virtual machines simultaneously, all working in parallel to solvesome problem. Doing this requires some way to schedule applications, i.e., to distribute theirwork across these instances. To allow this, Windows Azure provides the HPC Scheduler.Media

Video makes up a large part of Internet traffic today, and that percentage will be even larger

tomorrow. Yet providing video on the web isn't simple. Windows Azure Media Servicesprovides a set of cloud components that make life easier for people creating and runningapplications using video and other media.Commerce

The rise of Software as a Service is transforming how we create applications. It's alsotransforming how we sell applications. Since a SaaS application lives in the cloud, it makes


16/45


16

sense that its potential customers should look for solutions online. And this change applies todata as well as to applications. Why shouldn't people look to the cloud for commerciallyavailable datasets? Microsoft addresses both of these concerns with Windows AzureMarketplaceSDKsBack in 2008, the very first pre-release version of Windows Azure supported only .NETdevelopment. Today, however, you can create Windows Azure applications in pretty much anylanguage. Microsoft currently provides language-specific SDKs for .NET, Java, PHP, Node.js,and Python. There's also a general Windows Azure SDK that provides basic support for anylanguage, such as C++.These SDKs help you build, deploy, and manage Windows Azure applications. They're availableeither from www.windowsazure.com or GitHub, and they can be used with Visual Studio andEclipse. Windows Azure also offers command line tools that developers can use with any editoror development environment, including tools for deploying applications to Windows Azure fromLinux and Macintosh systems.

3.2.3 Microsoft System Center 2012

Microsoft System Center 2012 is a comprehensive management platform that enables you tomore easily and efficiently manage your IT environments, including your serverinfrastructure and client devices.Microsoft System Center 2012 offers solutions for managing datacenter resources, privateclouds, and client devices.

3.2.4 Microsoft Office 365

Microsoft Office 365 is the online productivity suites. Office 365 includes online versions ofWord, Excel, PowerPoint, and Outlook, as well as Lync and SharePoint. Together, thesecomprehensive and powerful online office tools represent the best overall value you can findtoday.

Office Apps :

If you are familiar with Office 2007 or Office 2010, youll feel comfortable working in Office

365. The Web incarnations of the Office apps have stripped-down versions of their respectiveRibbons, but the overall feel is the same, and the core features are present.Compatibility

When it comes to document fidelity--maintaining formatting consistency from a Microsoft

Office program to a cloud-based equivalent and back again (or vice versa)--no onlineproductivity platform is perfect.You won't necessarily be able to add or edit many of the more advanced formatting elementsfrom the desktop Office tools (such as footnotes, headers, or a table of contents)Sharing and Collaboration

Office 365 provides some real-time collaboration capabilities in Excel and OneNote, but not inWord and PowerPoint. Microsoft recently rolled out a coauthoring function for the Word WebApp, but it works only when you're sharing files from the Windows Live SkyDrive file storageservice, and when you're using the Word Web App.Files and Storage

The basic Office 365 plan gives you 2GB of data storage space on SharePoint Online; additional

space costs $2.50 per gigabyte per user per month. For email, each user has 25GB, the same asGoogle Apps, on the entry-level plan--but higher Office 365 plans have unlimited email storage.Office 365 also has the biggest file attachments allowed, at 35MB.Price

Office 365 has a variety of plans for companies of different sizes and needs. The plancomparable to what Google Apps and Zoho Docs each provide is $6 per user per month (price asof August 26, 2011). Office 365 offers slightly more features and capabilities than the other two,so the additional dollar per user per month seems justified.

3.3 Amazon

Amazon offers following five major services

Amazon Elastic Compute Cloud (Amazon EC2)Amazon Elastic MapReduceAmazon Relational Database Service (RDS) (IAAAmazon Simple Storage Service (S3).

Amazon Elastic Block Storage (EBS)

3.3.1 Amazon Elastic Compute Cloud (Amazon EC2)

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable computecapacity in the cloud. It is designed to make web-scale computing easier for developers.

Amazon EC2 presents a true virtual computing environment, allowing you to use web serviceinterfaces to launch instances with a variety of operating systems, load them with your customapplication environment, manage your networks access permissions, and run your image using

as many or few systems as you desire.

To use Amazon EC2, you simply:

Amazon Elastic MapReduce (Amazon EMR) is a data analysis tool that simplifies the set-up andmanagement of a computer cluster, the source data, and the computational tools that help youimplement sophisticated data processing jobs quickly.


21/45


21

Typically, data processing involves performing a series of relatively simple operations on largeamounts of data. In Amazon EMR, each operation is called a step and a sequence of steps isa job flow. A job flow that processes encrypted data might look like the following example.

Step 1 Decrypt data

Step 2 Process data

Step 3 Encrypt data

Step 4 Save data

Amazon EMR uses Hadoop to divide up the work among the instances in the cluster, tracksstatus, and combine the individual results into one output.

Amazon EMR takes care of provisioning a Hadoop cluster, running the job flow, terminating thejob flow, moving the data between Amazon EC2 and Amazon S3, and optimizing Hadoop.

3.3.3 Amazon Relational Database Service (Amazon RDS)

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to setup, operate, and scale a relational database in the cloud. It provides cost-efficient and resizablecapacity while managing time-consuming database administration tasks, freeing you up to focuson your applications and business.

Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle or MicrosoftSQL Server database engine. This means that the code, applications, and tools you already usetoday with your existing databases can be used with Amazon RDS. Amazon RDS automaticallypatches the database software and backs up your database, storing the backups for a user-defined

retention period and enabling point-in-time recovery.

Amazon RDS Functionality

Amazon RDS is designed for developers or businesses who require the full features andcapabilities of a relational database, or who wish to migrate existing applications and tools thatutilize a relational database. It gives you access to the capabilities of a MySQL, Oracle or SQLServer database engines running on your own Amazon RDS database instance.

To use Amazon RDS, you simply:

Use the AWS Management Console or Amazon RDS APIs to launch a DatabaseInstance (DB Instance), selecting the DB Engine (MySQL, Oracle or SQL Server),License Type, DB Instance class and storage capacity that best meets your needs.

Connect to your DB Instance using your favorite database tool or programminglanguage. Since you have direct access to a native MySQL, Oracle or SQL Server


22/45


22

database engine, most tools designed for these engines should work unmodified withAmazon RDS.

Monitor the compute and storage resource utilization of your DB Instance, for noadditional charge, via Amazon CloudWatch metrics available using the AWSManagement Console DB Instances tab or Amazon CloudWatch APIs. If at anypoint you need additional capacity, you can scale the compute and storage resourcesassociated with your DB Instance with a few clicks of the console or a simple APIcall.

Pay only for the resources you actually consume, based on your DB Instance hoursconsumed, database storage, backup storage, and data transfer.

3.3.4 Amazon Simple Storage Service (Amazon S3)

Amazon S3 is storage for the Internet. It is designed to make web-scale computing easier fordevelopers. Amazon S3 provides a simple web services interface that can be used to store andretrieve any amount of data, at any time, from anywhere on the web. It gives any developeraccess to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazonuses to run its own global network of web sites. The service aims to maximize benefits of scaleand to pass those benefits on to developers.

Amazon S3 Functionality

Amazon S3 is intentionally built with a minimal feature set.

Write, read, and delete objects containing from 1 byte to 5 terabytes of data each. Thenumber of objects you can store is unlimited.

Each object is stored in a bucket and retrieved via a unique, developer-assigned key. A bucket can be stored in one of several Regions. You can choose a Region to

optimize for latency, minimize costs, or address regulatory requirements. Amazon S3is currently available in the US Standard, US West (Oregon), US West (NorthernCalifornia), EU (Ireland), Asia Pacific (Singapore), Asia Pacific (Tokyo), SouthAmerica (Sao Paulo), and GovCloud (US) Regions. The US Standard Regionautomatically routes requests to facilities in Northern Virginia or the PacificNorthwest using network maps.

Objects stored in a Region never leave the Region unless you transfer them out. Forexample, objects stored in the EU (Ireland) Region never leave the EU.

Authentication mechanisms are provided to ensure that data is kept secure fromunauthorized access. Objects can be made private or public, and rights can be grantedto specific users.


23/45


23

Options for secure data upload/download and encryption of data at rest are providedfor additional data protection.

Uses standards-based REST and SOAP interfaces designed to work with any Internet-development toolkit.

Built to be flexible so that protocol or functional layers can easily be added. Thedefault download protocol is HTTP. A BitTorrent protocol interface is provided to

lower costs for high-scale distribution.

Includes options for performing recurring and high volume deletions. For recurringdeletions, rules can be defined to remove sets of objects after a pre-defined timeperiod. For efficient one-time deletions, up to 1,000 objects can be deleted with asingle request.

Reliability backed with the Amazon S3 Service Level Agreement.

3.3.5 Amazon Elastic Block Store (EBS)

Amazon Elastic Block Store (EBS) provides block level storage volumes for use with AmazonEC2 instances. Amazon EBS volumes are off-instance storage that persists independently fromthe life of an instance. Amazon Elastic Block Store provides highly available, highly reliablestorage volumes that can be attached to a running Amazon EC2 instance and exposed as a devicewithin the instance. Amazon EBS is particularly suited for applications that require a database,file system, or access to raw block level storage.

Features of Amazon EBS volumes :

Amazon EBS allows you to create storage volumes from 1 GB to 1 TB that can bemounted as devices by Amazon EC2 instances. Multiple volumes can be mounted tothe same instance.

Storage volumes behave like raw, unformatted block devices, with user supplieddevice names and a block device interface. You can create a file system on top ofAmazon EBS volumes, or use them in any other way you would use a block device(like a hard drive).

Amazon EBS volumes are placed in a specific Availability Zone, and can then beattached to instances also in that same Availability Zone.

Each storage volume is automatically replicated within the same Availability Zone.This prevents data loss due to failure of any single hardware component.

Amazon EBS also provides the ability to create point-in-time snapshots of volumes,which are persisted to Amazon S3. These snapshots can be used as the starting pointfor new Amazon EBS volumes, and protect data for long-term durability. The samesnapshot can be used to instantiate as many volumes as you wish.


24/45


24

AWS also enables you to create new volumes from AWS hosted public data sets. Amazon CloudWatch exposes performance metrics for EBS volumes, giving you

insight into bandwidth, throughput, latency, and queue depth. The metrics are

accessible via the AWS CloudWatch API or the AWS Management Console. For moredetails, see Amazon CloudWatch.
