CLOUD COMPUTING A BETTER MEANS OF INFORMATION TECHNOLOGY OUTSOURCE
The research focuses on cloud computing as a better means of it outsourcing. It provides an analytical framework in the nature of cloud computing, Characteristics and source models. It also provides a detail study in cloud computing as a better means of it outsource.
Cloud computing is a model for enabling ubiquitous, convenient on-demanding network access to a shared pool of configurable computing resources (e.g networks, servers, storage applications and services) that can be rapidly positioned and released with minimal management effort or service provider interaction.INFORMATION TECHNOLOGY
Although this widely-adopted description of what makes a cloud computing solution is very valuable, it is not very tangible or easy to understand. Why is cloud computing different than just visualization alone which is commonly mistaken to be cloud computing as well.INFORMATION TECHNOLOGY
Cloud computing is composed of fine essential characteristic, three deployment models and four service models.
The essential characteristics consist of:
a) On-demand self service: Users are able to position cloud computing resources without requiring human interaction, mostly done through a web based self service portal (management console).
b) Broad network access: Cloud computing resources are accessible over the network, supporting heterogeneous client platforms such as mobile devices and workstations
c) Resource pooling: Service multiple customers from the same physical resources, by securely separating the resources n logical level
d) Rapid elasticity: Resources are positioned and released on demand and/or automated based on triggers or parameters. This will make sure your application will have exactly the capacity it needs at any point of time
e) Measured service: Resource usage and monitored measured and reported (billed) transparently based on utilization.
Therefore, cloud computing is much more than just virtualization. It’s really about utilizing technology as a service. Users need little to no knowledge in the details of how a particular service is implemented on which hardware, on how many CPUs and so on. All that is important for a user is to have good understanding of what the service offers and what it does not and how to operate the self service portal.INFORMATION TECHNOLOGY
