What is Cloud Computing?

Cloud computing is a general term for the delivery of hosted services over the Internet.

Cloud computing enables companies to consume a utility (similar to electricity or a telephone service) rather than building and maintaining computing infrastructures.

Benefits of Cloud Computing

Cloud computing promise several attractive benefits for businesses and end users. Three of the main benefits of cloud computing include: Self-service provisioning: End users can spin up

computing resources for almost any type of workload, on-demand and without direct intervention from IT administrators.

Elasticity: Companies can scale up as computing needs increase and then scale down again as demands decrease.

Pay per use: Computing resources are measured at a granular level, allowing users to pay only for the resources and workloads they use.Created by Imran Ahmed (ImranahmedIT) www.imran-ahmed.co.uk

Three pillars of The Cloud

To define cloud computing, it's important to look at all three pillars of cloud. A cloud is classified as:

Private

Public

Hybrid

Private Cloud

A private cloud is created within a business' data center and provides services to internal users. This model offers cloud's versatility, while preserving management, control and security.

In the public cloud model, a third-party provider delivers the cloud service over the Internet. Three distinct characteristics differentiate public cloud computing from in-house or hosted data centres.

Public Cloud

Public cloud is sold on-demand, typically by the minute or the hour.

Customers only pay for the computing resources they use, such as CPU cycles, storage or network bandwidth.

It is highly elastic, adding or subtracting resources on-demand.

Hybrid Cloud

Hybrid cloud is a combination of public cloud services and on-premises private cloud – with orchestration and automation between the two.

Companies can run mission-critical workloads or sensitive applications on the private cloud while using the public cloud for "bursty" workloads that must scale on-demand.

The goal of hybrid cloud is to create a unified, automated, scalable environment. Created by Imran Ahmed (ImranahmedIT) www.imran-ahmed.co.uk

Three Broad Service Categories

Although the cloud computing definition has changed over time, cloud computing has always been divided into three broad service categories:

Infrastructure as a service (IaaS)

Platform as a service (PaaS)

Software as service (SaaS).

IaaS

IaaS providers such as AWS supply a virtual server instance and storage, as well as application program interfaces (APIs) that let users migrate workloads to a virtual machine (VM).

Users have an allocated storage capacity and start, stop, access and configure the VM and storage as desired.

IaaS providers offer small, medium, large, extra-large, and memory- or compute-optimized instances, in addition to customized instances, for various workload needs.

PaaS

In the PaaS model, providers host development tools on their infrastructures.

Users access those tools over the Internet using APIs, Web portals or gateway software.

PaaS is used for general software development, such as Java or Perl, and to create custom applications.

A PaaS provider often hosts the software after it's developed.

Common PaaS providers include Salesforce.com's Force.com, Amazon Elastic Beanstalk and GoogleApps.

SaaS

SaaS is the cloud software distribution model that delivers services over the Internet; these are often called Web services.

Microsoft Office 365 is a SaaS offering for productivity software and email services.

Users can access SaaS applications and services from any location using a computer or mobile device that has Internet access.

Benefits for small organisations (1)

No more infrastructure investments will be required or time spent adding new servers to maintain storage. With the cloud, there is unlimited storage capability and scalability.

Manual backup tapes are not needed as most cloud providers across service types and platforms offer automatic backup and recovery capabilities.

Benefits for small organisations (2)

Cloud mobility enables access anywhere with a Web connection (just about) and can be very secure (e.g. VPN)

Updating and managing software or applications via the cloud can be cost effective and it also helps save on-site energy costs.

Helps reduce manual system administration and provides automatic tools saving time and making tasks more efficient which ultimately makes jobs much easier and more enjoyable. Created by Imran Ahmed (ImranahmedIT) www.imran-ahmed.co.uk
