In this article, we shall be discussing a detailed report about Platform as a Service. Some of the salient points we shall be considering include the service providers, how developers are using PaaS, the benefits and demerits, the features offered and the overall market size. Developers want to focus on coding and business owners prefer focusing on running and scaling their business rather than managing app backend infrastructure. That is why using a Platform as a Service to handle infrastructure is a no-brainer for businesses worldwide.  PaaS is a widely used cloud solution commonly used to rest, run, deploy and upgrade apps. Businesses and developers prefer this model because they don’t have to mess with databases, middleware, infrastructure and other technical hassles. This article provides an excellent guide for those who are learning about Platform as a Service for the first time. It provides a step-by-step guide that delves into details such as benefits, demerits, examples of PaaS deployments and a review of the top service providers.

A Quick Overview of PaaS

Platform as a Service is a type of cloud-solution that offers both infrastructure and a platform as an ongoing service. With this type of service, people who want to build apps can access a platform with everything they need to develop, launch, manage and grow their app business. The best part is that the service provider takes care of ongoing infrastructure and software management.

What does PaaS do exactly?

The term PaaS is the acronym that means Platform as a Service. This type of cloud solution provides companies with cloud-based application and hardware resources they need to achieve their objectives. Users of this service can build, store, deploy, test, update and manage their apps without hassles.

In essence, companies are no longer constrained to acquire hardware and software to build their apps on-premise.  Below are the main services that PaaS offer:

  • It provides the hardware required such as internet access, processing power, server machines, storage and lots more.
  • Offers leading-edge tools required for app development projects
  • Provides app security through network firewalls and other functions.
  • Offers tools to test, debug, deploy and host apps.

What does PaaS do?
PaaS Main Features

PaaS Features

Below are the main PaaS features

What is a Container Runtime?

A container typically designed to have predetermined computing power. These computing resources are used to carry out application building, hosting, and running tasks. Apps in containers can be deployed on a shared or dedicated computing environment.  It is the container runtime manages how containers allocate resources for a containerized app ti=o run flawlessly.   Gives the mission critical nature of containers, they must be configured to be secure, follow predetermined standard and run in am isolated environment. It is the container runtime to helps accomplish these requirements. The runtime sets security rules and ensures apps get the computing resources allocated to it.

Management of Infrastructure

One of the core features of PaaS is that the service provider offers continued infrastructure management.  This type of Cloud computing solution replicates the offerings of Infrastructure as a Service, and offers much more. Beyond providing security, computing power, cloud storage, network and servers, PaaS also offers analytics, operating system, database business intelligence and development resources.

Develop, Design and Test Apps

Besides providing the hardware, PaaS providers also support users with software they need to achieve their objectives.  A cross section of these software resources debuggers, compilers, and code editors that are useful for designing resting and debugging apps. These tools can be accessed easily from any location though a web browser interface

Provision of Middleware

The companies that offers PaaS stands in-between app user and the server machines. They provide the resources that allows developers to build and manage programs that the app users see. AS a results, companies using PaaS don’t need to hire developers to build middleware that makes their app accessible to end users.

Databases Support

One of the core offerings of PaaS service providers is the database.  While the type of database offered differs among PaaS vendors, they all offer maintenance for the database they provide. Depending on the vendor, database support may range from offering database management systems to complete database management, and other enterprise options.

Monitoring Tools and Management Resources

The providers of PaaS services o above and beyond providing resources to help build, host and deploy apps. The offer additional tools continued app monitoring and management. A few of these add-on services include Business Intelligence products like Microsoft Cloud Monitoring, Amazon Cloud Watch, and Amazon QuickSight.

The Operating System

The PaaS provider provides server machines bundled with the operating system as well. The operating system is the program that powers every other application that is used for app development projects.

Security Features

PaaS plans are bundled with default security functions. Some of these security features include token management, encryption technology, logging, security protocols and many more. Since PaaS platforms deploys the latest technologies, they empower their platform users to leverage the leading-edge security models for app deployment and continued management.

Scaling Your App

PaaS vendors allows their platform users to scale server resources horizontally and vertically without having to lift a finger. This automatic scaling feature empowers businesses and developers to focus on their core competences while the PaaS service providers manage resource availability to ensure service continuity.

PaaS service providers also offers platform users to choose the type of resource scaling they prefer. Those who prefer not to implement automating resource scaling can scale their resources up and down manually with a couple of clicks.

Continuous Integration & Delivery

The procedure for implementing intermittent code adjustment in a central code repository without hampering service delivery is called Continuous Integration and Delivery. This technology also makes room for continuous code monitoring. In essence, continuous integration create value that expedites app development and code reliability.

In like manner, Continuous Delivery empowers developers to build deploy and test their apps faster than ever.  This technology negates the need for extensive app testing before its release. Therefore, the cost and timeframe of building apps is reduced extensively.

Paas Advantages

The Advantages of PaaS

Below are the main advantages of using PaaS platforms.

Convenient and Easy to Use

The procedure for launching and continuous app management on PaaS platforms is quite straightforward. The PaaS service providers offers top-notch tools with user-friendly interface for their platform users. These tools can be accessed remotely from a web browser interface.

As you can see, this kind of cloud solution helps company cut costs and avoid the hassles of maintaining infrastructures in their offices.

Minimize Development Tasks

With PaaS the engineering assignments required to build functional apps is reduced significantly. Bundled services like version upgrade, script editor, app tester, storage, code compiling, database and networking goes a long way in reducing development assignments. Developers can leverage these services to build apps faster with lesser hassles since they don’t have to bother with infrastructure management.

Expedites Time to Market

PaaS enhances development assignment compared to developing apps the conventional way because it allows developers to focus on creating excellent codes and testing to make sure it’s perfect. Therefore, small and large businesses can expedite time to market with PaaS, giving them a competitive edge over the competitors that don’t use this cloud service model.

Negates Infrastructure Management

The procedure for managing IT infrastructures like networks and servers are challenging. Apart from paying for the expensive hardware, you must still acquire software, manage them, pay for energy costs and upgrades when the need arises. However, with PaaS, all these hassles are not necessary.

Build Apps for Multiple Platforms

Writing different codes for various platforms can be cumbersome and costly. However, PaaS providers like Asure and AWS allow developers to write a single code and deploy to multiple platforms like mobile, web and Desktops.

Manage App’s Lifecycle

PaaS providers offers services that cater to the app’s development and continued growth and ongoing management as long as the app exists. This is called Application Lifecycle Management (ALM). Therefore, the additional expenditure of acquiring an ALM tool is not required. Better still, PaaS application life management tools are available for cloud and on-premise apps.

Dynamically Scalable 

An app’s requirements for server resources do increase as the userbase grows with time. Therefore, there is a need to increase the available resource, and PaaS is great at scaling resources dynamically. It takes just a few clicks within the PaaS admin interface to increase server instances and backend resources of an app.

PaaS Limitations

Flexibility and Control Limits

One of the major issues with PaaS is that it offers the platform users limited control and flexibility as opposed to on-premise options. PaaS platform users cannot change the configuration of infrastructure as they like.  Moreover, if there is a breakdown on the PaaS provider’s end, the platform users can do nothing about it.

Higher Costs Compared to IaaS

The costs of getting PaaS up and running is higher than IaaS. However, it is important to bear in mind that PaaS offers software resources which will eventually be an additional cost when setting up an IaaS to host apps.

Lock-In by Vendors

The challenge of getting locked-in permanently on a PaaS platform us a major drawback for developers. The option of migrating an app from one PaaS vendor to another is quite burdensome and will involve a considerable downtime.


Programming Language Support Issues

While the top PaaS platforms support the commonly used programming languages, they do not support all. So, chances exist that your choice programming language may not be supported. Another potential issue is that a PassS vendor may decide to stop supporting a specific programming language. This can be a big blow when affected.

Compatibility of Existing Structure

There could be compatibility challenges when trying to integrate an existing app into a new PaaS platform. The compatibility issue may also arise when an app synergizes the power of multiple PaaS platforms. This article, PaaS – Pros & Cons sheds more light on the benefits and demerits of PaaS.

Types of PaaS Providers

Types of PaaS

There are several types of PaaS service offerings, but here are the most popular ones


Public PaaS works in the open internet and handles complex computing requirements like networks, server machines, saving important files, and managing data, all within a public cloud. Accessing public PaaS online is a straightforward process. Many public PaaS services allow you to test them out for free, or you only pay when you use them.

However, even though Public PaaS helps businesses by taking care of complex software and computer system setup, it can sometimes make it difficult for businesses to switch to other options, and there might be concerns about how safe it is.


Private PaaS is a different type that gives virtual resources in a private internet space within the company. This special kind of internet space doesn't just keep things more private for businesses but also gives them more power over what they do. Seamless scaling, top-notch security, and being able to change how things work are all good things about using Private PaaS.

Unfortunately, Private Cloud uses the company's own internet stuff, so businesses must handle the installations, do upgrade when the need arises, and oversee ongoing management.


The hybrid PaaS model synergizes the power of private and public cloud. For instance, a company may have an existing private cloud, but would want to add a public cloud to scale storage or enhance availability. In essence, the hybrid setup would use an on-premise data center as well as a public cloud service. 

Platform as a Service Vs. Other Cloud Models

The following factors set PaaS apart from other cloud computing models.
