The Role of PaaS Providers

Before going to the functioning of PaaS providers, it is necessary to know what PaaS is. The Platform as a Service (PaaS) is a model where developers rent everything required to build an application, relying on a cloud provider for development tools, infrastructure, and operating systems, thereby vastly reducing web application development time.

Role of PaaS providers and what they have to offer

·        Development tools: PaaS providers offer a variety of tools that are necessary for software development, including a source code editor, a debugger, a compiler, and other essential tools. It should include everything a developer needs to build their application.

·        Middleware: PaaS providers typically include middleware so that developers do not have to build it. Middleware is software located between user-facing applications and the machine's operating system and is necessary for running an application. End-users, however, do not interact with it.

·        Operating system: A PaaS provider operates and maintains the operating system that developers work on and the application runs on.

·        Databases: Administering and maintaining databases is one of the key responsibilities of PaaS providers. Additionally, they also offer developers a database management system as well.

·        Infrastructure: In the cloud computing service model, PaaS is placed a step above IaaS. All that is included in IaaS is also there in the PaaS as well. PaaS providers, therefore, either manage servers, storage, and physical data centers or purchase them from an IaaS provider.            

PaaS helps developers to build applications faster than would be possible if they had to spend time worrying about building, configuring, and provisioning their own platforms and backend infrastructure. With PaaS, all they have to do is write the code and test the application, and the PaaS providers handle the rest.

Docker and its Place in Cloud Computing

Docker is a tool in cloud computing that automates the deployment of applications in an ecosystem that is designed to manage containers. These containers enable applications to function while being shifted from one platform to another. Docker has a distinctive technology that focuses on what developers and systems need. This state-of-the-art technology ensures that enterprises can create and run any product from anywhere.
