With the advent of Cloud computing, it has become easier for the business organization to maintain secrecy of their internal data’s and building various business applications. To make the process simple and Cloud computing eliminates the cost and complexity of buying, evaluating, configuring, and maintaining all the hardware and software needed for enterprise applications. As an alternative, these applications are delivered as a service over the Internet.
Cloud computing has included platforms for building and running applications, so that the use of it become really easy and accessible for the subscribers. PaaS or “Platform as a Service” is introduced in cloud computing where you can write and create your own Software as a Service (SaaS). This software is extremely beneficial and allows developers to quickly deploy Java Spring applications on your choice of cloud service providers. Open PaaS service enables customers to build and arrange applications on numerous frameworks and several clouds.
Apart from the in-house network model, running on-site applications has always proved complex and expensive without Platform as a Service, as each single application requires hardware, an operating system, Web servers, a database, middleware and a lot more. Big companies often required expensive facilities to house their data centers and also extensive electricity were also needed to power the servers and to keep them cool. Also a failover site was needed to mirror the data center so there was a backup in case of a disaster. PaaS offers a more effective and cost efficient model for application development and delivery.
With the Platform as a Service model, cloud hosts provide all the infrastructure and services needed to develop applications over the Internet. Also when you are using PaaS, you must remember it is based on usage based fee structure so users only pay for the amount they have used. PaaS has made a new age of mass innovation. Developers can access unlimited computing power sitting at any corner of the globe. Now, anyone and everyone can build applications, all you need to have is an internet connection.
PaaS services can be attained globally without concern for the geographical boundaries. Initial and ongoing costs can be reduced by the use of infrastructure services from a single vendor rather than maintaining multiple hardware facilities that often perform redundant functions or run into incompatibility issues. But there are certain things that you need to take care of before availing the PaaS services, that it might require proprietary service interfaces or intricate programming languages. Organizations and companies must cautiously choose their cloud host looking after the facilities, capacity, scalability and pricing.
