Why we use cloud computing?

Why we use cloud computing? Case 1: Write a file Save Computer down, file is lost Files are always stored in cloud, never lost

Why we use cloud computing? Case 2: Use IE --- download, install, use Use QQ --- download, install, use Use C++ --- download, install, use …… Get the serve from the cloud

What is cloud and cloud computing? Demand resources or services over Internet scale and reliability of a data center.

What is cloud and cloud computing? Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a serve over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them.

The architecture of cloud computing system

Characteristics of cloud computing Virtual. software, databases, Web servers, operating systems, storage and networking as virtual servers. On demand. add and subtract processors, memory, network bandwidth, storage.

Types of cloud service SaaS Software as a Service PaaS Platform as a Service IaaS Infrastructure as a Service Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore

Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore SaaS Software delivery model No hardware or software to manage Service delivered through a browser Customers use the service on demand Instant Scalability Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore

Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore SaaS Examples Your current CRM 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. Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore

Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore PaaS Platform delivery model Platforms are built upon Infrastructure, which is expensive Estimating demand is not a science! Platform management is not fun! Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore

Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore PaaS Examples 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. 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. Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore

Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore IaaS Computer infrastructure delivery model A platform virtualization environment Computing resources, such as storing and processing capacity. Virtualization taken a step further Sometimes called Utility computing Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore 18

Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore IaaS Examples 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. Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore

Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore Shrek, Delgo, and Others Why did Dreamworks use this? Upsides? Downsides? Dr.S.Sridhar, Director, RVCT, RVCE, Bangalore 23

Grid Computing & Cloud Computing share a lot commonality intention, architecture and technology Difference programming model, business model, compute model, applications, and Virtualization.

Grid Computing & Cloud Computing the problems are mostly the same manage large facilities; define methods by which consumers discover, request and use resources provided by the central facilities; implement the often highly parallel computations that execute on those resources.

Grid Computing & Cloud Computing Virtualization Grid do not rely on virtualization as much as Clouds do, each individual organization maintain full control of their resources Cloud an indispensable ingredient for almost every Cloud
