Comparison of SAAS, PAAS and IAAS

There are generally three concepts of cloud service, software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). Be it IaaS, SaaS, and PaaS, each has its own complexities, but today we will help you differentiate SaaS, PaaS, and IaaS.

SaaS: software as a service It is generally charged according to the number of users and the charges are monthly or annual. Companies 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 software ownership by eliminating the need for technical staff to manage installation, manage and update software, as well as reduce the cost of software licensing.

PaaS – Platform as a Service, A cloud service, which typically provides 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 operating systems in general. All applications built with PaaS include cloud features such as scalability, availability, and multi-tenancy. 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 build on their strength and save them from having to deal with the app’s hosting platform. PaaS providers are more responsible for dealing with servers and their main 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 scalability and application development of their product or service.

IaaS – Infrastructure as a Service – A cloud service that allows users to gain 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 the service offerings. The service provider must take care of these devices or virtual machines, including any services they depend on, for example, networking, hardware, or operating system patches. This basic service is interesting for a number of uses, especially for highly customized software that cannot work in PaaS or even SaaS. The disadvantage is that for this service the user must have appropriate experts for all the lower level technologies like the operating system and more. This type of service offers more flexibility for any online software, but also requires more technical skills in different areas.

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

With this article, we hope to describe what cloud computing is, how we use it, and how you can help our customers benefit from it.
