Introduction to Cloud Computing

"Cloud computing is a buzzword..."

What is Cloud?The term cloud has been used historically as a metaphor for theInternet.

What is Cloud Computing?Cloud computing describes a new supplement, consumption anddelivery model for IT services based on Internet, and it typicallyinvolves the provision of dynamically scalable and often virtualizedresources as a service over the Internet.
















Evolution of Cloud Computing

Hardware EvolutionDifferent generations of computer.

Internet Software EvolutionThe Internet is named after the Internet Protocol, the standardcommunications protocol used by every computer on the Internet.

Server VirtualizationVirtualization is a method of running multiple independent virtualoperating systems on a single physical computer.

Layers of Cloud Computing Architechture

Client: Computer hardware or software that relies on cloudcomputing for application delivery.Application: Software as a ServicePlatform: Platform as a ServiceInfrastructure: Infrastructure as a ServiceServer: Computer hardware or software products that arespecifically designed for the delivery of cloud services, includingmulti-core processors, cloud-specific operating systems andcombined offerings.


















Web Services Delivered from the Cloud

XaaS/EaaSEverything as a service (EaaS, XaaS,*aaS) is a concept of being ableto call up re-usable, fine grained software components across anetwork.It is a subset of cloud computing. The most common andsuccessful example is software as a service (SaaS), but the as aservice moniker has been associated with many other functionsincluding communication, infrastructure and platforms, most of whichare core components of cloud computing.



Software-as-a-Service (SaaS)Infrastructure-as-a-Service (IaaS)Platform-as-a-Service (PaaS)Other Services:

Communication-as-a-Service (CaaS)Data-as-a-Service (DaaS)Network-as-a-Service (NaaS)























SaaS: Software as a serviceThe major service given as part of Cloud Computing services.The first service.Most Known and used.

The application itself is provided by the service provider.Example:

Enterprise: SalesForce.Com, Webex, OfficeLiveUser Mail: Gmail, HotmailUser Pics: Flickr, Picasa

































IaaS: Infrastructure as a serviceService providers offers capacity for rent, basically hosted DataCenters ServersAn evolution of web site and server hosting services whichprovided servers and VPS

Examples:Amazon Web ServicesMain Services

Deployment Models of Cloud Computing

Public CloudThe services are delivered to the client via the Internet from a thirdparty service provider.Vendors: Amazon, Google, Microsoft, Salesforce etc.Infrastructure: Amazon, Rackspace, Gogrid, Joyent,Terramark etc.

Community CloudCommunity cloud shares infrastructure between several organizationsfrom a specific community whether managed internally or by athird-party and hosted internally or externally.

Private CloudThese services are managed and provided within the organization.Vendors: IBM, Vmware, HP, Oracle (Data Centers) etc.Infrastructure: Eucalyptus, 3Tera, IBM, Vmware etc.

Hybrid CloudThere is a combination of services provided from public and privateClouds.Example: ERP in Private cloud and Sales and Email on public














Virtualization Technology

Virtualization is a term that refers to the abstraction of computerresources.Types of Virtualization:

Resource Virtualization: Any part of computing resource can bevirtualized. e.g. Virtual MemoryPlatform Virtualization: The whole system is virtualized. e.g.Server Virtualization

Scope of VirtualizationServer ConsolidationHigh Availibility Disaster RecoveryInfrastruction OptimizationInfrastructure AutomationClient VirtualizationIntelligent InfrastructionSecured ComputingApplications


















Types of Platform VirtualizationParavirtualization, requiring porting of guest systemsHardware-assisted virtualization, allowing for unmodified guests

Virtualization is based on insertion of ahypervisor on top of hardware.Virtual machine (VM), a softwareimplementation of a machine (computer) thatexecutes programs like a real machine.Virtual machine manager (VMM), ishardware virtualization techniques that allowmultiple operating systems, termed guests,to run concurrently on a host computer.


























Xen Hypervisor

XenA virtual machine monitor providing services that allow multiplecomputer operating systems to execute on the same computerhardware concurrently.

The first guest operating system, called in Xen terminology domain 0(dom0) The system administrator can log into dom0 in order tomanage any additional guest operating systems, called user domains(domU) in Xen terminology.Xen’s support for virtual machine live migration from one host toanother allows workload balancing and the avoidance of downtime.

Challenges

ExtensibilitySimple architecture and open internal APIs

Client-side interfaceAmazonâs EC2 interface and functionality (familiar and testable)

NetworkingVirtual private network per cloudMust function as an overlay => cannot supplant local networking

SecurityMust be compatible with local security policies

Packaging, installation, maintenancesystem administration staff is an important constituency for uptake






Security

All Eucalyptus components use WS-security forauthentication

Encryption of inter-component communication is not enabled bydefaultConfiguration option

Ssh key generation and installation ala EC2 is implementedCloud controller generates the public/private key pairs and installsthem

User sign-up is web basedUser specifies a password and submits sign-up requestCert is generated but withheld until admin. approves requestUser gains access to cert. through password-protected web pageSimilar to EC2 model without the credit cards






Conclusions

Eucalyptus was designed from the ground up to be easy to installand as non-intrusive as possible (can be installed on a laptop forexperimentation)Highly modularExternal interface is based on highly popular API of Amazon(industry standard interface)Unique among the open-source offerings in providing a virtualnetwork overlay
