Today, cloud dominates in the IT world due to the many ways by which it has enabled businesses to solve their major IT concerns like cost, durability, flexibility, performance, security, operability, expertise, man effort, extendibility, scalability etc. The innovation of Cloud Computing and its associated technologies have revolutionized the IT world and most SMEs and almost all enterprises are heavily utilizing and harnessing the powers of cloud technologies.
A cloud based infrastructure is actually an ecosystem for your IT needs. It contains numerous components starting from the base hardware to the cloud software and then the analytics and monitoring tools. All these are integrated well and work in a pluggable architecture to provide you with capabilities for fault-proof computations, data storage and access, delivering services, development and deployment of your products etc. A good cloud infrastructure needs to have the crucial features of high availability, horizontal scalability in which your enhanced and growing IT and business requirements are met by adding up more logical resources rather than adding separate physical systems including hardware and computational platforms. Here is where the popular open source cloud softwareOpenStack helps you in achieving your goals. OpenStack helps in building your IT environment as Infrastructure as a Service (IaaS) that runs on commodity hardware and a number of component services on top of it that provides services for compute, storage, networking, dashboard etc. This service segregation into components is the key to achieving horizontal scalability with OpenStack.
Amazon AWS and EC2 are public cloud services implemented through an API driven infrastructure while OpenStack supports all private, public and hybrid cloud models through server based virtual machine technologies. According to AWS, Amazon EC2 is a web service that provides resizable compute capacity in the cloud and is designed to make web-scale cloud computing easier for developers. According to OpenStack, it controls large pools of compute, storage and networking resources throughout a data center, managed through a dashboard or through the OpenStack API. OpenStack works with popular enterprise and open source technologies making it ideal for heterogeneous infrastructure.
