- 2. Introduction to Cloud Computing Cloud Computing Architecture Service Models Types of Cloud Virtualization Why/Why not Recommended Cloud Computing Case-Study Conclusion Contents
- 3. An environment created in a user’s machine from an on-line application stored on the cloud and run through a web browser. In addition, the platform provides on demand services, that are always on, anywhere, anytime and anyplace. The hardware and software services are available to general public, enterprises, corporations and business markets What is Cloud Computing
- 6. Service Models SaaS PaaS Iaas Web Browser Cloud Development Environment Visual Infrastructure Manager. Cloud Application Social networks, Office suits, CRM, Video processing Cloud Platform Programming languages, Frameworks, editors, Structured data Cloud Infrastructure Compute Servers, Data Storage, Firewall, Load Balancer Service Class Main Access & Management Tool Service Content
- 7. Most known and first service, major service given as part of cloud computing service Is an application that can be accessed from anywhere on the world as long as you can have an computer with an internet connection. Consumer does not manage or control the underlying cloud infrastructure including network, services, operating systems, storage E.g. Google Apps, Microsoft Office 365, Gmail, Hotmail, Picasa, Salesforce Software-as a Service (SaaS)
- 8. Give us API(Application Programming Interface) and take care of the implementation. It is a platform for developers to write and create their own SaaS i.e application. In this model, cloud providers delivers a computing platform and/or solution stack typically including operating system, programming language execution environment, database and web server. E.g. Google’s App Engine, Amazon EC2, Microsoft Azure Platform-as a Service (PaaS)
- 9. This is computing power that you can rent for a limited period of time. An evolution of web site and server hosting services which provided servers and virtual private servers. Cloud providers offer computers as physical or more often as virtual machines, raw storage, firewalls, load balancers and networks. E.g. AT&T-Hosting and Storage, Windows Azure, HP, Amazon EC2 Infrastructure-as a service(IaaS)
- 10. Comparison - Service Models
- 11. Public Cloud Used by multiple tenants on a shared basis Hosted and managed by cloud service provider Limited variety of offerings Lower upfront cost Economies of scale Simpler to manage OpEx E.g. Amazon, Google, Microsoft, Sales force Types of Cloud
- 12. Private Cloud Exclusively used by a single organization Controlled and managed by in-house IT Large number of application Lower total cost Greater control over security, compliance & quality of service Easier Integration CapEx & OpEx E.g. HP data center, IBM, Sun, Oracle Types of Cloud
- 13. Hybrid Cloud Usage of both public and private together called hybrid cloud Organization may host critical apps on private clouds. Types of Cloud
- 14. Virtualization is “ something which is not REAL, but displays the full qualities of the REAL. Virtualization Provides: -Hardware Platform -Operating System -Storage device -Network resources - Software implementation Virtualization
- 15. Single OS image per machine Software and hardware tightly coupled Running multiple application on same machine often creates conflict Inflexible and costly infrastructure. Before Virtualization
- 16. Hardware-independence of operating system and applications. Virtual Machines can be provisioned to any system. Can manage OS and application as a single unit by encapsulating them into Virtual Machines. After Virtualization
- 17. Why/Why Not Recommend Cloud Computing Why??y? Achieve economies of scale Reduce spending on technology infrastructure Back up and recovery Reduce capital cost Improve accessibility Monitor project more effectively Easy access to information Improve flexibility Why Not?? Technical Issue Security Prone to attack Lack of Control
