What Is Platform as a Service (PaaS)?
Platform as a service (PaaS) is a cloud computing platform where a third party offers the necessary software and hardware resources. These offerings enable clients to develop, run, and manage business applications without maintaining the infrastructure required for such software development processes.
Today’s digital world is constantly bombarding organizations with newer technologies and data. This large volume of information is making it difficult for legacy environments to keep up. Owing to the data explosion, businesses are shifting to cloud infrastructure as a feasible option. PaaS solutions cope with modern business requirements while considerably reducing costs and complexities of buying, installing, and managing in-house hardware and software.
SaaS vs. PaaS vs. IaaS
A typical PaaS model encompasses the physical infrastructure, cloud applications, and a graphic user interface (GUI). PaaS architectures are similar to serverless computing or function-as-a-service (FaaS) models. In such models, the operating infrastructure is not in sight of the developers and users. This compels the cloud service provider to control the operations of underlying servers and resources. The PaaS framework uses a dynamic financial model. The computing services are priced based on computations, storage space, and network resources.
According to the Platform as a service (PaaS) Global Market Report 2021: COVID 19 Impact and Recovery to 2030 by Reportlinker, the global PaaS market was valued at $47.29 billion in 2020. It is expected to grow 14.4% in 2021. This high growth rate is mainly due to companies restructuring their business operations to recover from the pandemic and tackle operational challenges due to closed commercial activities. The market is projected to reach $88.11 billion by 2025, expanding at a CAGR of 13% over the forecast period.

Key Components of Platform as a Service
Different PaaS vendors offer different types of services. The core components of these services are listed below.
- Development tools: The most important component of platform as a service is the tools required by engineers for software development purposes. These include a source code editor, debugger, compiler, and other essential tools that assist in writing, deploying, debugging, and managing code. These developmental tools may be offered together as a framework. Depending on clients’ needs, vendors offer specific tools, but a PaaS model should essentially include everything that a developer would require to build an application.
- Middleware: Middleware is similar to an invisible entity (i.e., software) that allows users to interact with the software. It acts as an intermediate bridge between user-facing applications and machine operating systems. Middleware enables applications to understand keyboard entries or mouse clicks that are input by a user.
- Operating system (OS): PaaS provides any or all operating systems that developers need to work on and on which applications run. The developer, however, need not worry about using the latest version of the OS or updating it for security patches. Hence, the OS is a fundamental component provided by PaaS vendors.
- Databases: PaaS allows developers to create, query, and maintain databases needed to develop and deploy applications.
- Infrastructure: In PaaS, all infrastructure components, including storage and servers, are taken care of while developing and deploying applications. A PaaS vendor either manages servers, storage, and physical data centers or purchases them from a third-party provider. This allows development teams to focus on application-building rather than worrying about the infrastructure itself.

Top 10 Best Practices for Implementing PaaS in 2021
While implementing PaaS, designing an architecture for each environment (development, testing, staging, and production) per the organizational workflow and applications is vital. Enterprises should be well-aware of their applications to plan for an architecture that suits the type of applications that are intended for deployment.
Although an individual PaaS setup may vary depending on the number of clusters that the enterprise requires, considering the right architecture is an important step in successfully implementing PaaS. Let’s look at the top 10 best practices to help you plan successful PaaS implementation in 2021.
PaaS Implementation Best Practices
1. Define a business goal
While businesses try to adopt PaaS, it is important to bear in mind the reason for this change at every stage of the project. The reason could be for greater cloud efficiency, agility, or even to lower the cost of on-premise infrastructure and maintenance. Determining the goal in advance allows the enterprise to monitor if the project is on track at each step of the way.
Several businesses decide to move to the cloud by following the route taken by their peers without any concrete reason or goal in mind. This can harm business output. Hence, defining a compelling business goal to go down the PaaS path is inevitable for its successful implementation.
2. Develop a roadmap
Once you align PaaS with your business goals, you will need to chalk out a plan about the process. Organizations should analyze whether all applications need to be migrated to the cloud or whether they can be reworked instead. They also need to have an idea about how PaaS adoption or implementation by workload migration will impact other operations and, if the impact is huge, how they can minimize disruption.
This also calls for developing a leadership team that includes executives from the business and IT to handle the primary lines of business while the organization undergoes the necessary change. Additionally, businesses can also look at incorporating public, private, multi-cloud, or a hybrid combination of cloud and on-premise processes per its need.
3. Run a pilot project
After developing a strategy, businesses can verify and validate the migration and new system by running a pilot. This allows them to fail and re-align their issues at the initial stages rather than undertaking full-scale migration that risks failure later on. Besides, while running the pilot, enterprises can keep track of application flexibility among public, private, and hybrid cloud, and on-premise environments, for better PaaS performance.

4. Work out the budget
Results of the implemented pilot will allow businesses to forecast and predict the total cost. Otherwise, parameters such as incorrect autoscaling, failure in accurate forecasts leading to buying on-demand capacity, and automatic turning on certain services can lead to higher expenditure. Hence, working out the exact picture related to the cost and how to operate the PaaS platform is important.
5. Orchestrate backups
Once the decision is made to adopt PaaS, organizations should ensure that all data is backed up before the actual migration. This allows the enterprise to continue to meet its recovery time objectives (RTOs) and recovery point objectives (RPOs), so that operations are carried out without any disruption in the future.
6. Ensure effective communication
For successful PaaS implementation, it’s important to involve all the stakeholders (CEO, CTO, COO, and CIO) and keep them well-informed on the PaaS adoption plans, migration schedule, and important milestones in the entire process. Communication allows the business and service owners to forecast when and which resources are required (stages) for complete PaaS adoption.
It also provides owners a chance to give feedback on the roadmap of the PaaS implementation, such as technical requirement changes, modernization requirements, and many others. As such, organizing a monthly or quarterly discussion forum with the stakeholders and replaying roadmap status and current activities can boost the success of PaaS implementation.

7. Test the PaaS solution
While performing PaaS migration, organizations need to test their platform to ensure success. They also need to check if users can access the required data and systems. Also, the smooth functioning of the software and hardware integrations under the PaaS platform needs to be checked and verified.
8. Ensure platform security
Cyberattack vulnerability exposes the risk of data loss. Hence, PaaS adoption calls for making security a priority. Organizations need to be aware of the PaaS provider’s security measures to ensure that the systems and data are not vulnerable to an attack, even for a few minutes. Additionally, security during cloud migration should also be considered.
9. Address compliance requirements
While leveraging PaaS, cloud usage and storage regulations should be addressed simultaneously. Cloud services should be in line with the Health Insurance Portability and Accountability Act (HIPAA), Payment Card Industry (PCI), the EU’s General Data Protection Regulation (GDPR), or other applicable laws or guidelines to ensure that all the necessary compliance requirements are fulfilled.
10. Leverage the experts
To successfully deploy PaaS architecture, understanding the above points related to cloud migration is vital. This calls for knowledge, skill, and probably, some experience on a few cloud migrations. Hence, being an experienced CIO, seasoned IT professional, or software developer alone won’t serve the purpose.
Working with experts will make it easier to choose the right kind of products, tools, and security solutions for your organization. It will also help regulate the costs of the deployed cloud computing model. Besides, a cloud expert can also ensure increased user adoption, which will most likely garner a greater return on investment.

Modern businesses are driven by fast-paced and highly agile environments that can adapt to real-time scenarios and bring about change immediately. Platform as a service fits into such a framework. It allows organizations to build customized applications and solutions with the aid of advanced tools and software machinery. Fundamentally, PaaS adoption avoids the reinvention of the cartwheel and reuses existing processes. This implies that developers need not code everything from scratch. Instead, they can just plug and play the pre-built reusable blocks provided by the PaaS provider. This eventually helps in rapid app development and deployment.
Leveraging PaaS can have many benefits for an organization; however, cloud migration has to be done correctly. This is because migrating to the cloud means managing movement while avoiding data loss, operational disruptions, or high-cost models. Therefore, one needs to proceed cautiously and reach out for help whenever needed.
