Cloud is now increasingly becoming the prime workhorse of enterprises.
The capabilities that cloud provides, which include scalable infrastructure, self service administering, and pay per use model are being effectively leveraged by businesses to fuel growth.
Cloud hosting services by offering state of the art features, dramatically simplify infrastructure planning and deliver direct cost benefits.
Software as a Service is a service delivery model that is transforming the way businesses build, sell, purchase and use software. In this platform a cloud user accesses applications from browsers without the need for deploying hardware.
In short SaaS is web based software, hosted software or on-demand software. Cloud hosting services shoulder the primary task of maintaining the application, its security, uptime, and performance.
SaaS has the capability to deliver end user software to thousands of clients by using a multitenant platform. This offers significant benefits to end users by way of saving in costs related to servers and software licensing.
High-end performance is another appealing feature of SaaS. With the introduction of Web 2.0 and fast HTML standards, SaaS is able to deliver graphically rich applications that perform with great speed.
• For the user client
• For cloud hosting services
o Advantage of flexible pricing based on usage
o Optimum efficiency and ease of maintenance
o Ability to deliver scalable and customizable applications
In this model cloud hosting services deliver a platform for clients, on which they can develop, run, and manage web application without the need to own and maintain on- premise infrastructure.
Some drawbacks exist such as the need for reliable connectivity and robust security, but cloud hosting services have effectively addressed these issues.
2. Platform as a Service (PaaS)
In other words, PaaS is middle ground, or a service that allows IT developers test and run applications without the worry about underlying infrastructure.
1. Improved performance while developing and deploying applications.
2. Reduced costs related to server and storage overheads. PaaS delivers the developmental tools with the result clients do not have to store all the iterations of the code.
3. Infrastructure as a Service (IaaS)
In an Infrastructure as a Service model, cloud services host hardware, applications, server, storage and other infrastructure components on behalf of the user client.
IaaS platforms offer highly scalable resources enabling clients pay-as-you-use flexibility.
With IaaS in place, enterprises need no longer worry whether the infrastructure will keep pace with competition and adapt to the pressure to innovate.
In simple terms, IaaS is an all inclusive service. Cloud hosting services provide each component as a service, for example; hardware as a service, server as a service, and cloud computing and cloud storage as a service.
IaaS is ready to consume service freeing companies’ time so that managers can focus on applications and solutions.
Cloud hosting is now facilitating enterprises to successfully implement intricate IT projects in a simplified manner.
