Timeline
What is Cloud Computing?
It is Internet-based(³Cloud´) development and use of computer technology (³computing´). It is one of next industry buzz words. It joins the ranks of terms including: grid computing, utility computing, virtualization, clustering, In this dynamically scalable & often virtualized resources are provided as a service over the Internet.
The Hype
Cluster Computing Cloud Computing Grid Computing
Who said what ?
³a cloud is a pool of virtualized resources that can host a variety of different workloads, allow workloads to be deployed and scaled-out quickly, q y, allocate resources when needed, and support Redundancy´ -Greg Boss et al., IBM ³«computation may someday be organized as a public utility «´
- John McCarthy,
1960
Expand your Infrastructure! Buy new servers, increase your software costs, provision more datacenter capacity!!
Look to the cloud! Pay for the bandwidth and server resources that you need. When your push is done then turn the whole thing off!
What is Cloud?

Types of Clouds
Private Cloud Public Cloud Hybrid Cloud
Public Cloud
Open for use by general public
Exist beyond firewall, fully hosted and managed by the vendor Individuals, corporations and others Amazon's Web Services and Google app Engine are examples
Offers startups and quick setup, scalability, flexibility and automated management. Pay as you go model helps startups to start small and go big
Public Cloud«(contd.)
Large scale infrastructure available on a rental basis
Operating System virtualization (e.g. Xen, kvm) provides CPU isolation ³Roll-your-own´ network provisioning provides network isolation
Fully customer self-service
Service Level Agreements (SLAs) are advertized Requests are accepted and resources granted via web services Customers access resources remotely via the Internet
Accountability is e-commerce based
Web-based transaction ³Pay-as-you-go´ and flat-rate subscription Customer service, refunds, etc.
Private Cloud
Within the boundaries(firewall) of the organization All advantages of public cloud with one major difference
Reduce operation costs Has to be managed by the enterprise
Fine grained control over resources More secure as they are internal to org Schedule and reshuffle resources based on business demands Ideal for apps related to tight security and regulatory concerns Development requires hardware investments and in-house expertise Cost could be prohibitive and cost might exceed public clouds
Hybrid Cloud
Combines features of both private and public cloud. It just like having a account on remote pc. Privacy of data is retained.
Cloud computing - Characteristics
Agility ± On demand computing infrastructure
o Linearly scalable ± challenge
Reliability and fault tolerance
o o Self healing ± Hot backups, etc SLA driven ± Policies on how quickly requests are processed
Multi-tenancy ± Several customers share infrastructure, without compromising
privacy and security of each of the customer¶s data
Service-oriented ± compose applications out of loosely coupled services. One
service failure will not disrupt other services. Expose these services as API¶s
Virtualized ± decoupled from underlying hardware. Multiple applications can run in
one computer
Data, Data, Data
o Distributing, partitioning, security, and synchronization

Definition
PaaS
Platform providing all the facilities necessary to support the complete process of building and delivering web applications and services, all available over the Internet Entirely virtualized platform that includes one or more servers, operating systems and specific applications
Popular services
PaaS Storage Database Scalability
Advantages
PaaS Pay per use Instant Scalability Security Reliability APIs
Examples
PaaS Google App Engine Mosso AWS: S3
IaaS Infrastructure as a Service
Computer Infrastructure delivery model
Definition
Provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. Infrastructure as a Service is sometimes referred to as Hardware as a Service (HaaS). The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis

More Examples
SaaS
Your current CRM(Customer Relationship Management) package is not managing the load or you simply don¶t want to host it in-house... use a SaaS provider such as Salesforce.com
Your email is hosted on an exchange server in your office and it is very slow« outsource this using Hosted Exchange.
You need to host a large file (5Mb) on your website and make it available for 35,000 users for only two months duration. Use Cloud Front from Amazon.
PaaS
You want to start storage services on your network for a large number of files and you do not have the storage capacity«use Amazon S3.
You want to run a batch job but you don¶t have the infrastructure necessary to run it in a timely manner. Use Amazon EC2. You want to host a website, but only for a few days. Use Flexiscale.
IaaS
SaaS
Advantages
PaaS Lower cost of ownership Reduce infrastructure management responsibility Allow for unexpected resource loads Faster application rollout
