Introduction To Cloud Computing

The term Cloud refers to a Network or the Internet. In other words, we can say that Cloud is something, which is present in a remote location. The cloud can provide services over a network, i.e., on public networks or on private networks, i.e., WAN, LAN, or VPN. Applications such as e-mail, web conferencing, and customer relationship management (CRM), all run in the cloud.

Manipulating, configuring, and accessing applications online is referred to as Cloud Computing. In this architecture, we do not need to install software on our local PC. We can overcome the platform dependency issue through cloud computing. It makes our business application mobile and collaborative.

Infrastructure As A Service (IAAS) IaaS provides access to essential resources such as physical machines, virtual machines, virtual storage, etc. Platform As A Service (PAAS) PaaS provides the runtime environment for applications, development & deployment tools, etc. The software As A Service (SAAS) SaaS model allows using software applications as a service to end users.

There are many other service models that can take the form of XaaS, i.e., anything as a Service. This can be Network as a Service, Business as a Service, Identity as a Service, Database as a Service, or Strategy as a Service. Infrastructure as a Service (IaaS) is the most basic level of service.

Service-Oriented Architecture helps to use applications as a service for other applications regardless of the type of vendor, product, or technology. Therefore, it is possible to exchange data between applications of different vendors without additional programming or making changes to the service
