CLOUD COMPUTING -----------------------------------.pdf
- 1. CLOUD COMPUTING --------------------------------------------------------------------------- 1)By this users on various types of devices can acces programs,storage,processing,and even application development platforms over the internet which is placed in providers location and in their systems they will maintain that.so many companies can use that by paying them. By this the the person using this have cost savings,high availability ,and easy scalability. 2)Working in a large platforms owned by providers and shared by numerous users makes cloud computing less expensive,according to proponents. 3)Shifting to cloud computing will dramatically reduce the cost of information technology. this is main benefit for the user and the vendor also get profited because he only store and provide the service to user so that he knows how much memory he has to ,and data also. 4)It lowers the cost of application development and makes the process more scalable. 5)The main role of providers is they create separate cloud-computing business units and dedicated data centers to make sure the systems function optimally and maximize their revenue-generation potential. 6)Small clients run their applications and services housed elsewhere and accessed via a network. 7)Major clou-computing services are Amazon web services,google Apps,Microsofts windows azure provides cloud based computing resources to the user. 8)Cloud services infrasturcture is designed to host multiple tenants with high service levels over long periods of time. 9)For implementing cloud-computing organizations generally just have to set up a secure accoutn account with the provider. 10)Providers bill users based on the number of minutes or hours they spend on a cloud system or on their level of consumption of resources such as bandwidth consumed,data transferred ,storage space filled. 11)There are four types of services the cloud offers to the user i)Iaas:Infrastructure as a service In this products deliver a full computer infrasturcture via the internet. ii)Paas:Platform as a service Products offer a full or partial application development environment that users
- 2. can access and utilize online,even in collaboration with others iii)SaaS:Software as a service they provide complete ,trunkey application,including complex programs such as CRM or enterprise-resource management via the internet. 12)Cloud computing foucuses on turning aspects of the IT computing stack into commodities that can be purchased incrementally from the cloud based providers and it is type of Outsourcing in many cases. 13)thus the cloud computing focuses on the distribution of business and personal data across servers on the internet. Ex: an individual can have personal data in Facebook,Digital photos in flicker,banking data in bank servers all available in distributed servers and data centers around the world. Cloud computing and SOA: --->Both cloud computing and SOA provides an organization with an oppotunity to select common standards for network accessible capabilities. -->SOA has faily matured set of standards where as cloud computing not as mature and many of the interfaces offered are unique to a particular vendor.which is not possible in SOA.
