A Modern Architecture for Open Source Cloud Computing
Main Article Content
Abstract
With the advent of Web 2.0 and Software as a Service, cloud computing has come into vogue. Cloud computing has become
synonymous with providing services anywhere anytime with the basic requirement being access to the internet. As a new model, cloud
computing promises to make any online service available without a large upfront investment in infrastructure. The economics of running a full
infrastructure changes dramatically since you only pay for what you use. And you can provision capacity for only what you require at any given
time. Many companies who have supported their own needs for large-scale, distributed computing are beginning to export their technologies and
services to support others. Open source is important in all aspects of cloud computing. It is used to build the core of the cloud and its services. In
this paper we proposed architecture for open source service cloud computing which will avoid vendor lock-in and scalability. We detail the
functional architecture and the core structure implementing such paradigm. The model divides the cloud computing system with various
components in open source 3-layer hierarchy called infrastructure, platform and application.
