  • 1. Definitions“A pool of abstracted, highly scalable, and managed computer infrastructure capable of hosting end-customer applications and billed by consumption”“Cloud computing is an emerging approach to shared infrastructure in which large pools of systems are linked together to provide IT services.”
  • 2. The “Cloud Computing ” advantages• Ease of Use• Scalability• Risk• Reliability• Cost
  • 3. Ease of Use• Deploy infrastructure with a mouse or API – No cabling, screwdrivers, racking, unboxing, buying – Middle of the night – Do it yourself remotely from anywhere anytime
  • 4. Scalability1.Control your infrastructure with your applicationdemands.2.No need to purchase expensive hardwares forscalability.
  • 5. Risk1. Nothing to buy2. Cancel immediately3. Change instantly, even operating systems4. Throw it out5. Rebuild it instantly after testing RISK
  • 6. Reliability1. Based on High quality hardware2. Design for failures: › Automatically spin up replacements › Use multiple clouds
  • 7. Cost1. Pay for only what you use2. No need to buy in advance3. Zero Capital Outlay4. No contracts
  • 8. Defining the Segments• SaaS – Software as a Service• PaaS – Platform as a Service• IaaS – Infrastructure as a Service Storage as a Service
  • 9. Cloud “Applications”• In SaaS no need to buy expensive licensed applications• Examples: SalesForce, Gmail, Yahoo! Mail, Quicken Online• Instead of selling you a copy of Microsoft Word for $300, a cloud computing model would "rent" word processing software to you through the Internet for perhaps 5 dollars a month.• Advantages: Free, Easy, repair a single central copy of the product online• Disadvantages: Limited functionality, no control or access to underlying technology, you have to trust into the online software vendors.
  • 10. Cloud “Platforms”• “Containers”• “Closed” environments• Examples: Google App Engine(support only java & python), , 16 languages)[5] ,Windows Azure(.Net,java,Php), Mosso, Engine Yard, Joyent• Advantages: Good for developers, more control than “Application” Clouds, tightly configured• Disadvantages: Restricted to what is available, other dependencies
  • 11. Cloud “Infrastructure”• Provide “Compute” and “Storage” clouds• Virtualization layers (hardware/software)• Examples: Amazon EC2, GoGrid, Amazon S3, Nirvanix, Linode• Advantages: Full control of environments and infrastructure• Disadvantages: premium price point, limited competition
  • 12. The “Cloud Pyramid”•Layers equate structure•Building blocks: Infrastructure, Platforms,Applications
  • 13. The “Cloud Pyramid” Inversed 1000’s of Cloud Applications currently Handful of Cloud Platforms Elite group of Cloud Infrastructure providers # of Marketplace providers
  • 14. Cloud “Extenders”• Provides extension to Cloud Infrastructure and Platforms with basic functionality• Examples: Amazon SimpleDB, Amazon SQS, Google BigTable• Advantages: Extends functionality of Compute & Storage Clouds to integrate with other clouds• Disadvantages: Sometimes requires use of specific Platforms or Infrastructure
  • 15. Cloud “Aggregators”• Sits on top of various Cloud Infrastructures for management• Examples: RightScale, Appistry• Advantages: Provides more options for Cloud environments• Disadvantages: Dependent on Cloud Providers
  • 16. The NEW “Cloud Pyramid”
  • 17.• American multinational electronic commerce company. with headquarters in Washington.• It is the worlds largest online retailer. and is a major provider of cloud computing services.
  • 18. Amazon Web Services• Offerings• Hardware as a Service(HaaS) AWS-EC2• Storage as a Service – AWS-S3• Database as a Service – SimpleDB• Queuing as a Service – SQS
  • 19. Cont.. Aggregate Offerings•Pretty much anything you can think off•Oracle , Solaris , Hadoop Clusters (NY times),Specialized Applications (Vertica DB) , Animoto
  • 20. Amazon’s EC2• Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web- scale computing easier for developers.• EC2 is still largely used for batch-style, asynchronous jobs such as crunching large statistics or encoding video (although increasingly more are using it for their full web server setup)
  • 21. Cont..The auto-scaling open-source Amazon EC2.•Scalr is a recently open-sourced framework formanaging the massive serving power ofAmazon’s Elastic Computing Cloud (EC2) service.
  • 22. Amazon S3• Amazon S3 is storage for the Internet. It is designed to make web-scale computing easier for developers.• Data Security with Access Control and Using Data Encryption• Data Durability and Reliability
  • 23. Amazon SimpleDB• Amazon SimpleDB is a distributed database written in Erlang by It is used as a web service in concert with Amazon Elastic Compute Cloud (EC2) and Amazon S3.• “Amazon SimpleDB is a highly available and flexible non-relational data store that offloads the work of database administration. Developers simply store and query data items via web services requests and Amazon SimpleDB does the rest.”
  • 24. Amazon SQS• Amazon Simple Queue Service (Amazon SQS) is a distributed queue messaging service introduced by• Reliable• Simple• Scalable• Secure• Inexpensive
  • 25. Hosting Industry needs Change• Technology has evolved• People demand more control• Instant gratification• Managed is not dynamic enough Cloud Computing -“Enabling Technology” to move from Traditional Hosting to Cloud Hosting
  • 26. Colo vs. Managed vs. Cloud Hosting Colocation Managed CloudTime Weeks to Months Days to Weeks MinutesScalability Slowest, Rigid & Costly Slower, somewhat Instant, Flexible, Pay- flexible, Costly per-usageCost High Costly, sometimes No contracts, usage month/year contracts, based, no upfront costs“Green” Low Low High - virtualizedPricing model Buy Servers & Colo Rent Servers & Rent based on usage costs whether used or Hosting costs whether only not used or not
  • 27. Summary Infrastructure as a Service (IaaS) provides the user with virtual infrastructure, such as servers and data storage space. This is where virtualization fits into the cloud. Platform as a Service (PaaS) provides the user with development environment services where the user can create and run home-grown applications. Software as a Service (SaaS) provides the user with access to already created applications that are operating in the cloud.
