In this article, we will try to see the concepts of Cloud, IaaS (Infrastructure as a Service) and PaaS (Platform as a Service). Cloud computing has been part of the internet service delivery landscape for over a decade or even earlier. It is now very evident that the individuals who don’t do much of the coding or relate to the IT industry understand “the Cloud” thus mentioning the extent it has expanded. Along with it, there is a craze that has been started to understand DevOps and also to bring in the good stuff within an Organization and further within the industry.
Though the choice of choosing a Cloud environment is pretty straight-forward but choosing between an IaaS and in a PaaS service is quite difficult as each has their own requirements for the in-house expertise and also in customization and life-cycle management. With IaaS, the decision to bring in a big package of infrastructure services which includes network, server, storage and development tools has to be made. With such a situation, the question arises – does the team have the skills and does the team have the time to build this. Building your own IaaS development platform doesn’t just end up at the creation stage but also requires regular maintenance timeframes from the DevOps teams.

This doesn’t have to be for sure that PaaS (Platform as a Service) is not customizable. The key here is that it is a packaged and integrated one-stop toolkit. The need for the speed demands PaaS to be chosen over IaaS as PaaS comes with an automated development, deployment, provisioning, security and other application lifecycle management tools. The case with the PaaS user would be that the tool itself gets updates from its provider, hence relieving the teams of any further maintenance timeframes spent on them in totality. When deciding between IaaS and PaaS, you along with your Organization needs to take a calculated decision or else you might end up with a tool that doesn’t cater to all of your requirements.
Having discussed the various concepts of Cloud, Infrastructure as a Service and Platform as a Service – we now will take a look at various tools that fit into the DevOps chain of tools. Let us now take a look at each of these tools and also the advantages that these bring to the table when introduced into your Organization’s DevOps toolchain.
