What is PaaS in Cloud Computing?
A tech pro is usually required to build applications and work with them to make some of the tasks easier. While developing an application, you typically need a platform to work on.
Instead of building your own platform or purchasing one, you can leverage one provided by any of the cloud computing platforms. The services provided by these platforms make the app development easier and quicker, and that too at a very nominal cost.
One of the most popular services offered by cloud providers is the one we will discuss today, Platform as a Service.
Being a tech pro (which is obvious if you are reading this), you might know very well that everything is on the cloud; if it is not, it will soon be. So, cloud computing is the present as well as the future. You should know the cloud computing technology very well to stay updated with the tech and focus on performing your IT-related tasks quickly, eventually being more efficient.
Since companies have moved their business to the cloud, they need expert cloud professionals who can get the tasks done. They need experts who know the cloud platforms and the services provided by them very well. This is why cloud professionals are in demand everywhere.
To learn about the cloud computing platforms and their services in and out, you can go with a Cloud Computing certification bootcamp to upgrade your knowledge.
For now, let us discuss PaaS.
What is PaaS?
The third-party cloud services providers such as AWS, Microsoft Azure, Heroku, Google Cloud offer various cloud computing services that enable organisations to remotely operate their applications while making sure that the services are highly available via the internet.
The services are categorised into four types, namely PaaS (Platform as a Service), SaaS (Software as a Service), FaaS (Functions as a Service), IaaS (Infrastructure as a Service).
Platform as a Service, or simply PaaS, is a cloud computing model that provides users with a fully-fledged, high-performance development platform via the Internet connection.
Put simply, PaaS is a model where the third-party cloud services provider provides developers with software and hardware tools for developing robust applications over the Internet. The software and hardware are hosted by the platform in its own infrastructure, thereby freeing you from worries about installing in-house hardware and software to develop or run your application.
With PaaS, organisations no longer need to have their own range of resources and tools like Application Infrastructure Middleware (AIM), container orchestrators (such as Kubernetes), software licences, etc.
PaaS integrates storage, networks and servers, database management system, business intelligence services, as well as cutting-edge middlewares; PaaS enables quick development and deployment of applications regardless of their type (cloud-based or complex application, enterprise-class cloud application).
To deploy PaaS solutions, businesses can choose to go with a flexible pay-as-you-go model in all three cloud computing types, including public cloud, private cloud, or the hybrid cloud. PaaS just augments what already exists instead of replacing IT infrastructure.
The PaaS architecture comprises of three components:
- The Cloud Infrastructure: this comprises virtual machines, networking, firewalls, storage, as well as the operating system
- Software Tools: this component is used mainly for the development, deployment, and management of applications
- The Graphic User Interface (GUI): this simplifies the monitoring of workload throughout the entire lifecycle of developing applications
With the online GUI that is available within the PaaS architecture, an application developer can easily test, integrate, design, develop, and roll out applications from anywhere. The GUI also enables teams to streamline tasks and work on multiple projects of development at a time.
Working of PaaS
Typically, PaaS in cloud computing is intended for product development that is mainly related to software. It is a development-oriented cloud computing model that unlike others (SaaS and IaaS) is unable to accommodate non-development processes.
The online interface of PaaS provides a platform for development that consists of tools and resources that are accessible on the go by a simple login to the enterprise PaaS system from any device with Internet connectivity, thereby eliminating the geographical barriers. The flexibility and simplicity of the PaaS architecture enable organisations to focus on business-related issues.
Advantages of PaaS
With a wide range of benefits, PaaS enables developers to develop and deploy applications rapidly along with being cost-effective. The development and Business Intelligence tools, the middleware feature, provide organisations with the edge they require in this competitive environment. Some of the key advantages of PaaS are:
- Enhanced capabilities with a Smaller Workforce: PaaS provides organisations with state-of-the-art tools, components, and resources that strengthen development teams with improved capabilities without requiring businesses to hire professionals to maintain the infrastructure.
- Reduced time of coding: PaaS integrates security features, top-class development tools, pre-coded application components, directory services, thereby reducing a significant amount of time that would otherwise have been spent on coding new applications.
- Power-packed tools at a reasonable price: PaaS services are available with the pay-as-you-go model, so enterprises can take advantage of advanced analytics software, development tools, BI, and DBMS services that are usually expensive for small businesses.
- Development across different platforms: Most of the PaaS service providers allow you to choose from different development options across various platforms such as desktop computers, mobile devices, web browsers, thereby facilitating easier and faster development of cross-platform applications.
- Structured Application Lifecycle Management: PaaS provides organisations with all the resources, tools, and capabilities that are required to support the entire lifecycle of applications, from designing to development, deploying, testing, managing, and updating.
You are now acquainted with the overview of PaaS in cloud computing. To go hands-on with the services and have a good grasp of all the services under this cloud computing component, you can take up an online training course.
You will learn autoscaling, disaster recovery, Identity and Access Management, Database management, and many other services.
To go with hassle-free learning that allows you to learn at your own pace, Simplilearn can simplify the learning process and make you an expert cloud professional.
