Comparison of SAAS, PAAS and IAAS

There are generally three cloud service concepts, Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Whether it’s IaaS, SaaS, and PaaS, each have their own complexities, but today we’ll help you differentiate SaaS, PaaS, and IaaS.

SaaS: software as a service it is generally charged based on the number of users and charges are monthly or yearly. Businesses have the option to add or remove users at any time at no additional cost. Some of the best known SaaS solutions are Microsoft Office365, SalesForce, Google Apps. It is the responsibility of SaaS providers to manage insider threats related to server, network, and security. It supports the organization to reduce the cost of ownership of the software by eliminating the need for technical staff to manage the installation, administration and updating of the software, as well as reducing the cost of software licensing.

PaaS – Platform as a Service, A cloud service, typically providing a platform on which software can be developed and deployed; in short, it provides a platform for the software developer.

PaaS reduces the amount of coding required, automates company policy, and aids in the migration of applications to hybrid clouds. With PaaS, users can better manage servers, storage, networks, and overall operating systems. All applications built with PaaS include cloud features such as scalability, availability, and multitenancy. In addition, the process of creating, testing and launching applications is faster and cheaper.

PaaS uses infrastructure services and adds software platform services to it. The basic idea is to help the app developer develop their strength and avoid having to deal with the app hosting platform. PaaS providers are more responsible for dealing with servers and their primary role is to provide customers with an environment where the server operating system and software, as well as the server hardware and network infrastructure, are taken care of. This helps users focus on the business side of scaling and application development of their product or service.

IaaS – Infrastructure as a Service – A cloud service that allows users to get access to their own infrastructure: computers, network resources, storage. These can typically be virtual resources, but can also be actual physical resources.

This is the most basic of service offerings. The service provider must take care of these devices or virtual machines, including all the services on which they depend, for example, networks, hardware or operating system patches. This basic service is interesting for a number of uses, especially for highly customized software that can’t work on PaaS or even SaaS. The downside is that for this service the user has to have appropriate experts for all the lower level technologies like OS and more. This type of service offers greater flexibility for any online software, but also demands a greater amount of technical skills in different areas.

Many IaaS providers now also offer databases, message queues, and other services on top of the virtualization layer. Users benefit from IaaS as they get a complete infrastructure on top of which they can install any required platform.
