Information technology is a field that is globalizing rapidly that no one can think of stopping it. Everyday, there is some innovation in this field. Creativity and innovation are the two major policies of IT industries. One of the best gifts by the IT industry to the world is the cloud computing. This is a technology doing rounds now in every industrial sector. Almost everyone is familiar with cloud computing today. It can be used for personal as well as professional purpose. Hybrid cloud provides you the best of both worlds. Service models of cloud computing are very important to understand.
First is the SaaS service (Software as a Service), which is the most talked about the cloud model. A server maintained over data centers hosts business applications. There are no extra hardware costs while using SaaS model. You are spared of the initial setup cost also as the application is ready to use as soon as you dial in. You get to pay only for what you use, and there are no extra hidden charges. Automated updates are there so you need not worry about that too. SaaS application is accessible through any device that supports the internet. You can customize the application later, according to your needs.
Next model is the IaaS model (Infrastructure as a Service). The service provided in this model can be accessed from any location. Compared to other cloud models, IaaS can be used to create an easily scalable and cost effective IT solution. The expense of managing the fundamental hardware is outsourced to the service provider, and complexities are also handled by them only. If the business group is looking for expanding they can easily do it with the cloud. Just log into it and make use of cloud resources. It will spare you the time and effort required to install and configure a new system. Third is the PaaS (Platform as a Service) cloud computing system that allows its clients to develop and build applications over the internet. Users can simply access it through their internet browser. It is one of the best solutions for people who want to build their own structure over their server rather than depending on the earlier provided ones.
