Saas infrastructure or software as a service is one of the simplest cloud computing systems that a business organisation or an individual can subscribe to. Here the user is provided with the basic application software as well as the database. The underlying infrastructures and the platforms on which the softwares run are of no concern to the end user. The cloud computing service provider handles this end while the user gets an uninterrupted use of the software it requires for running its business.
This infrastructure is also known as the on-demand software and the users have to pay a subscription fee based on their use of the software. Since the user has no idea of the platform or about the installation process, the process of maintenance and software security is managed entirely by the cloud providers, making it considerably easier than the platform based cloud computing.
The scalability of the on-demand software is done by cloning the various tasks into multiple virtual machines which change during their run time according to the demands of the users. The task is distributed adeptly by the local balancers which again use multiple virtual computers to do the needful. The user has no inkling of the complexity of these tasks and has to deal with only a single access point. Sometimes, a single machine serves a number of cloud users with each virtual machine catering to a particular task, common to a number of users. For instance, communication as a service, business as a service, testing as a service etc.
The pricing of software as a service is relatively simple too. The users are required to pay a flat fee for a monthly or annual use. The rate of charge is thus flexible depending on the users and is liable to change if the machines are scaled up or the number of users gets reduced. Microsoft Office 365, Google apps, and Gt Nexus are a few Saas that are readily available.
However, it will not be wise to blindly opt for the service without doing appropriate research. Checking out the security of your software is absolutely necessary. Any threat should be filtered out at the level of the network instead of you having to deal with it. Asking for a tour of the data centre is also acceptable before you commit yourself. Be sure to check out the flexibility of your service provider. You may actually want to do a transition depending on your business needs, so opting for a cloud implementation that will help you to grow further is going to be useful. Last but certainly not the least, look for expertise! Feel free to ask any question that you may have about Saas infrastructure. The service provider you select, must be confident enough to provide an ideal solution to all your problems.
