Cloud computing provides on-demand access to shared pools of configurable computing resources like networks, servers, storage, applications and services. Major providers like Amazon Web Services offer infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) through services like EC2, S3, SimpleDB and SQS. These services provide scalability, reliability, flexibility and reduce costs compared to traditional hosting.
![Cloud “Platforms”
• “Containers”
• “Closed” environments
• Examples: Google App Engine(support only java & python),
,Force.com(support 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](https://image.slidesharecdn.com/cloudcomputingbyamazon-120812185358-phpapp02/85/Cloud-computing-by-amazon-11-320.jpg)
Cloud computing by amazon
- 2. 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.”
- 3. The “Cloud Computing ” advantages • Ease of Use • Scalability • Risk • Reliability • Cost
- 4. 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
- 5. Scalability 1.Control your infrastructure with your application demands. 2.No need to purchase expensive hardware's for scalability.
- 6. Risk 1. Nothing to buy 2. Cancel immediately 3. Change instantly, even operating systems 4. Throw it out 5. Rebuild it instantly after testing RISK
- 7. Reliability 1. Based on High quality hardware 2. Design for failures: › Automatically spin up replacements › Use multiple clouds
- 8. Cost 1. Pay for only what you use 2. No need to buy in advance 3. Zero Capital Outlay 4. No contracts
- 9. Defining the Segments • SaaS – Software as a Service • PaaS – Platform as a Service • IaaS – Infrastructure as a Service Storage as a Service
- 10. 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.
- 11. Cloud “Platforms” • “Containers” • “Closed” environments • Examples: Google App Engine(support only java & python), ,Force.com(support 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
- 12. 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
- 13. The “Cloud Pyramid” •Layers equate structure •Building blocks: Infrastructure, Platforms, Applications
- 14. The “Cloud Pyramid” Inversed 1000’s of Cloud Applications currently Handful of Cloud Platforms Elite group of Cloud Infrastructure providers # of Marketplace providers
- 15. 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
- 16. 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
- 17. The NEW “Cloud Pyramid”
- 18. Amazon.com • American multinational electronic commerce company. with headquarters in Washington. • It is the world's largest online retailer. and is a major provider of cloud computing services.
- 19. 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
- 20. Cont.. Aggregate Offerings •Pretty much anything you can think off •Oracle , Solaris , Hadoop Clusters (NY times), Specialized Applications (Vertica DB) , Animoto
- 21. 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)
- 22. Cont.. The auto-scaling open-source Amazon EC2. •Scalr is a recently open-sourced framework for managing the massive serving power of Amazon’s Elastic Computing Cloud (EC2) service.
- 23. 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
- 24. Amazon SimpleDB • Amazon SimpleDB is a distributed database written in Erlang by Amazon.com. 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.”
- 25. Amazon SQS • Amazon Simple Queue Service (Amazon SQS) is a distributed queue messaging service introduced by Amazon.com. • Reliable • Simple • Scalable • Secure • Inexpensive
- 26. 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
- 27. Colo vs. Managed vs. Cloud Hosting Colocation Managed Cloud Time Weeks to Months Days to Weeks Minutes Scalability Slowest, Rigid & Costly Slower, somewhat Instant, Flexible, Pay- flexible, Costly per-usage Cost High Costly, sometimes No contracts, usage month/year contracts, based, no upfront costs “Green” Low Low High - virtualized Pricing model Buy Servers & Colo Rent Servers & Rent based on usage costs whether used or Hosting costs whether only not used or not
- 28. 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.
