Platform as a Service PaaS

This article will provide a comprehensive report about Platform as a Service. It will cover the market size, features, pros & cons, use cases, and providers.

Businesses and programmers always want to focus on their core competencies and code instead of deploying and handling infrastructure.

On this basis, the use of the Platform as a Service (PaaS) model of cloud computing is an excellent pick. Indeed, PaaS is a popular cloud model for setting up, running, testing, and upgrading applications without taking care of infrastructure, DBMS, middleware, and additional development tools. 

However, if you are new to PaaS or willing to explore every single aspect of Platform as a Service, then follow this guide. Yes, this article is going to discuss everything about PaaS, from pros, cons, and use cases to the best PaaS providers.


Platform as a Service Definition

Platform as a Service (PaaS) is a cloud computing model in which platform and infrastructure services are provided over the Internet. PaaS solutions provide application developers with an environment to build, deploy, manage and scale applications without having to worry about hardware considerations or software maintenance.

How does PaaS Work?

PaaS, or Platform as a Service, is a form of cloud computing that facilitates companies with software and infrastructural resources.

This broad cloud-hosted environment helps businesses to deploy, host, create, administer, update and test applications. 

Consequently, PaaS platforms release businesses to build applications from on-premises hardware or software installation. Here are the core services of PaaS:

  • Offers infrastructure resources, including storage, servers, computing, and networking through the internet
  • Provides development tools for designing and building an app
  • Confers networking firewall and several other security features
  • Helps in hosting, deployment, debugging, and testing 
  • Assists in database integration & management

In this regard, you can access the official page of any PaaS vendor and choose its services. Many PaaS providers offer users a free tier, but it is simple to proceed with pay-as-you-go pricing models. AWS, Back4App, Heroku, OpenShift, and Amazon Azure are renowned PaaS platforms. 

PaaS Features  

Here are the core characteristics of PaaS:

Container Runtime

A container typically consists of compute impulsions. These constraints are significant to carry out application building, hosting, and running tasks.

Moreover, containerized applications utilize shared and dedicated computers to perform different operations. On the other hand, container runtime is the program that enables the containers to execute operations in given operating systems.

Indeed, containers need to be set up in a fully standardized, secure, and confined manner. So, container runtime fulfills all of these responsibilities. Yes, container runtime confers several security boundaries and limits the consumption of resources among different applications in this regard. 

Managed Infrastructure

Managed infrastructure is another useful property of PaaS. Platform as a Service model of computing comprises all resources that IaaS confers, including servers, networking, storage, compute, and security. 

The additional support that PaaS offers developers in terms of managed infrastructure is the availability of development tools, database management, operating system, analytics, and business intelligence.

The maintenance and administration of these software and hardware supplies totally depend on the PaaS provider. 

Application Design, Testing & Development Tools

PaaS providers don’t only grant hardware support but also confer software resources. These software tools, such as script editor, compiler, and debugger, help to develop, design and test an application. Also, it is seamless to access and use these tools through a web browser remotely.


Platform as a Service vendors perform as a bridge between the machine’s OS and end-user apps and permits the programmers to approach input with the help of a mouse and keyboard.

As a result, PaaS users don’t have to hire developers to create middleware. However, end-users of an application can’t reach out to middleware. 


The provision of real-time databases and their regular maintenance is a vital feature of PaaS. In this regard, Platform as a Service vendors offer different types of database support with complete management or DBMS to businesses and development teams.

Monitoring and Management Tools

PaaS vendors don’t only help businesses in deploying, hosting, and building applications but also deliver services to monitor and administer applications.

In this regard, Platform as a Service providers confer a variety of Business Intelligence (BI) products. Amazon QuickSight, Amazon CloudWatch, and Microsoft Cloud Monitoring are examples of these management and monitoring tools. 

Operating Systems

Platform as a Service (PaaS) solutions are also responsible for catering and managing an operating system (OS). Basically, the operating system is used by programmers to run an application. 

Built-in Security

Another feature that catches the attention of businesses is the built-in security of PaaS. Indeed, PaaS vendors facilitate the users with numerous security protocols, protected event logging, encryption methods, and token administration.

Furthermore, PaaS also empowers businesses to utilize leading security practices while deploying and running an application. 


Although most PaaS platforms offer horizontal and vertical scaling of resources, PaaS also frees developers from the tension of extending infrastructural resources.

Yes, with PaaS vendors, programming teams can focus on the coding tasks and leave it to service providers to enlarge CPU, hardware, and software sources.

However, if you prefer something other than autoscaling, then it is also rapid to extend and reduce infrastructural resources within a few clicks only by using PaaS. 

Continuous Integration & Delivery

Continuous Integration (CI) permits the programmers to accommodate the code adjustments in a joint repository on a regular basis.

In this process, the script is also examined continuously. In this way, CI enhances development efficiency, and developers can build apps rapidly with great confidence.   

Similarly, Continuous Delivery (CD) is another approach that allows the development teams to create, launch and test an application within a short period of time.

With this practice, developers don’t have to test applications manually before release. So, it reduces development time and cost. 

Benefits of a Platform as a Service

Here are the core advantages of PaaS:

Simplicity & Convenience

Using PaaS platforms for businesses and developers is absolutely convenient and straightforward. PaaS vendors hand over software tools and infrastructure resources that programming teams and companies can access over the internet.

Yes, PaaS providers ensure the availability of these sources anywhere in the world through web browsers. 

So, this cloud model frees the companies from capital expenditures and maintenance of on-premises infrastructure. You just need to subscribe to these services and can proceed with per-use pricing models to access these services. 

Reduced Engineering Effort for Application Development

Platform as a Service vendors definitely overcome the burden of engineering teams to build applications. Indeed, PaaS platforms confer numerous services like networking, database, compiling, storage, testing, script editing, and app version upgradation.

Therefore, it becomes fast and smooth for software engineers to build applications. Furthermore, IT teams don’t have to take care of hardware structure when they use PaaS options. 

Faster Time to Market

Compared to conventional means of application development, it is agile to build and deploy apps with cloud models.

Mainly, with PaaS solutions, developers have to concentrate on the script and test the program because these services take care of the rest. 

As a result, startups and enterprises can fasten their time to market by using this cloud computing approach. It also gives them an edge over competitors that use on-premises solutions. 

No Need to Manage Infrastructure

IT infrastructure management is undoubtedly a challenging job. In this regard, businesses don’t only have to pay to install the hardware but also take responsibility for software, maintenance, and energy costs. PaaS vendors free companies from all of these headaches. 

Develop for Multiple Platforms

Developers also don’t have to design different codes for different platforms when they choose PaaS. Undoubtedly, prominent PaaS vendors like AWS and Azure enable programmers to deploy and create applications for various platforms, including mobile, web browsers, and desktops. 

Manage Application Lifecycle

Application Lifecycle Management or ALM PaaS is another benefit of using this cloud model. This continuous approach takes care of your app’s development, growth, functions, and governance throughout its existence. 

Moreover, developers don’t need to purchase ALM tools separately because PaaS vendors already offer this property. By the way, businesses can use ALM PaaS tools for both on-premises and cloud applications. 

Dynamically Scalable 

Businesses typically need more CPU, storage, and memory resources when their app grows. Hence, PaaS platforms are the best when it comes to extending such resources dynamically. Indeed, within a few clicks only, you can simply take your instances and resources on the fly while using Platform as a Service. 

Limitations of Platform as a Service

Less Control & Flexibility

Less control and flexibility are primary concerns of using PaaS vendors. Especially compared to on-premises solutions, businesses and developers have less control over data centers and infrastructure resources.

Likewise, if a PaaS vendor faces an outage or becomes a victim of a disastrous event, users will also meet the circumstances. 

Higher Costs Vs. an IaaS Implementation

If we compare the infrastructure cost of PaaS, then it is comparatively higher than IaaS, due to which developers consider IaaS implementation cheaper. But keep in mind you will also have to pay for software resources separately when you use IaaS. 

Vendor Lock-in

Vendor lock-in is a significant disadvantage of using PaaS. Indeed, businesses find it onerous to migrate their applications from one PaaS platform to another. Yes, it is challenging to transfer app data, and downtime is another peril in this regard. 

Some Programming Languages May Not Be Supported

Although leading PaaS providers support commonly used programming languages. But there are still some languages that Platform as a Service platforms don’t back.

Similarly, it could be catastrophic if a PaaS vendor halts providing support to a particular programming language after specific changes in its services. 

Compatibility of Existing Structure

Compatibility of an existing structure with a newly hired PaaS service could also be a limitation of using this cloud model. Mainly it could be problematic for companies if they are using combined PaaS services from different vendors.

Enterprises that are dipping their toes for the first time into cloud and software development services or are unable to deal with on-premises infrastructure can also go with PaaS.

Indeed, Platform as a Service platforms are helpful for large enterprises that need extensive infrastructure and workforce to take care of on-premises servers. 

Consequently, PaaS products reduce the capital expenditure, required technical staff, and energy bills of these companies. 

Types of Platform as a Service

Here are the main types of PaaS:


Public PaaS administers and supplies infrastructure components and software support, including networking, servers, storage and analytics in a public cloud. It is easy to approach public PaaS online. Also, the majority of Public PaaS services come with free-tier or just only ask for per-use fees.

Although Public PaaS prevents businesses from worries about software and hardware framework management but vendor lock-in and lack of security are its drawbacks.  


Private PaaS is another type that confers virtualized resources in an internal or private cloud. This type of cloud doesn’t only give more privacy to businesses but also offers more control. High scalability, enterprise-level security, and flexible instances are benefits of using Private PaaS.

Unluckily, Private Cloud utilizes on-premises infrastructure, so businesses need to take care of its management, upgradation, and installation. 


Hybrid PaaS is basically the combination of both private and public cloud types where businesses benefit from cloud services and on-premises data centers at the same time.

This type of PaaS is beneficial for companies that are already using private cloud and willing to get public cloud services to scale their operations. 

Platform as a Service Vs. Other Cloud Models

See the difference between PaaS and other cloud computing models here:

Infrastructure as a Service

Infrastructure as a Service, or IaaS, is a cloud computing form that confers virtualized tools, including network firewalls, servers, security, and storage.

Businesses, startups, and developers can access IaaS platforms according to their requirements through a per-use pricing model. 

Business continuity, high scalability, flexibility, fast development, and fewer capital expenditures are benefits of using the IaaS model. 

What are the differences between PaaS and IaaS?

IaaS platforms are designed to assist system administrators only, but PaaS is helpful for DevOps teams, programmers, database, and infrastructure executives.
