PaaS in Cloud Computing

Cloud computing has completely swept the technological world. In 2020 alone, approximately 61% of businesses moved their workloads to the cloud! Alongside it, other cloud services have grown and attracted massive numbers of customers and businesses, including PaaS. It is a large market, expected to be worth $216 billion in 2022. So, let's see what this popular cloud service has to offer, what's it about, and more!

What Is PaaS?

PaaS, or Platform-as-a-Service, is a cloud service type that delivers hardware and software to users via an Internet connection. It provides users with platforms like an OS, database, etc. Users that go with PaaS are usually looking to develop an application, and the PaaS provider hosts the hardware and software.

How Does PaaS Work?

PaaS is available to users via the provider's hosted infrastructure, as it does not replace a business' IT infrastructure for software development entirely. PaaS users mainly access this service through a web browser. PaaS providers can deliver this service via public, private, and hybrid clouds.

PaaS offers users OS, programming language execution environment, database, web server, and other such platforms. It also provides users with software for developing applications and includes a graphic user guide or GUI. Developers use the GUI to connect with each other and do all the work for the application they're working on, like testing new apps or rolling out finished projects. The PaaS service providers are the ones that maintain and manage the data centers and servers, while the users are responsible for the applications they use and their data.

Advantages & Disadvantages of PaaS

Advantages of PaaS

  • Faster time to market
    PaaS enables users to get their applications on the market faster because they don't need to download or install any hardware and software for the app, as PaaS does that for them. Users only need access to PaaS via the service provider, and they can start provisioning resources and working on their app right away

  • Various resources for a lower price
    PaaS service providers usually offer a wide range of different resources to users regarding application development. Some of those resources include operating systems, middleware, databases, development tools, etc. All of these resources and more are available in the same place for an affordable price

  • Freedom to test and experiment at lower risk
    Users can test, run and try out new operating systems, languages, etc., with PaaS without having to make substantial purchases or investments in them or anything related to them, like the infrastructure that's required to run them.

  • Scalability is simple and affordable
    PaaS makes scaling easy and cheap because it allows users to purchase and use additional capacity or other features whenever they need to. Compared to on-premise platforms, this process is relatively cheaper with PaaS. With on-premise platforms, users have to purchase additional compute, storage, and network capacity whenever they think that traffic spikes will happen. This often leads to the features being wasteful and idle, as they are not used when traffic is low, yet they are purchased. Also, if the user bought a certain amount of these features and realized that they could not satisfy the traffic spikes or unprecedented surges, the amount cannot be increased on time

  • Development teams have greater flexibility
    PaaS enables developers to access all the tools they need from any location because it provides a shared software development environment. Because of this environment, accessing and working on an application or other project is more effortless and readily available, making teamwork more practical

  • PaaS is a cheaper solution overall
    PaaS saves money by allowing a company to avoid the capital equipment costs of developing and scaling an application platform. PaaS can also lower or eliminate software licensing costs. Additionally, PaaS can lower your overall application management expenses by handling patches, updates, and other administrative activities

Disadvantages of PaaS

  • It's difficult to change your PaaS provider
    Once you decide on a PaaS service provider, it can be difficult to change it afterward. This is because the application you are building or have built is made using the tools that are exclusive to the provider's platform. Different providers can support different languages, libraries, APIs, architecture, or operating systems that are used to build and run the app. Usually, when developers want to change their provider, they either have to rebuild the application entirely or heavily modify it

  • Significant dependency on the provider
    Businesses can be heavily dependent on their PaaS providers due to the complexity of changing them. A minor change in the provider's core operations or infrastructure could significantly impact the performance of an application that was supposed to run smoothly on the previous setup. Moreover, if the provider's pricing strategy changes, an application's operating costs may increase dramatically

  • Issues with security and compliance
    With PaaS, the provider is responsible for storing most or all of the application's data and hosting the application's code. Some providers even use IaaS, a different type of cloud service, to store the data and code. Even though most PaaS providers are large businesses with enhanced security, it is impossible to properly examine and test the security measures safeguarding the application and its data. Furthermore, for businesses that must comply with rigorous data security standards, certifying the compliance of extra external providers would add to the time it takes to get to market

What Are Other Cloud Service Types?

  • SaaS - Software-as-a-Service delivers applications via the Internet like a service, and the provider manages all the hardware and software included. Some SaaS providers are Google Workspace, Salesforce, Slack, etc.
  • IaaS - Infrastructure-as-a-Service enables users to access physical and virtual servers and resources on-demand. Some IaaS providers are DigitalOcean Droplets, Microsoft Azure Storage, Google Compute Engine, etc.

What Is the Difference Between SaaS and PaaS?

The main difference between SaaS and PaaS is that SaaS offers you complete software. You can do anything from managing customer data and workflows with no additional programming or modifying on your part. Compared to PaaS, which offers a platform on which to deploy and build custom applications, SaaS is significantly more rounded and inclusive. With SaaS, the provider manages and maintains everything, leaving only the data created by the SaaS app in your hands.

All you need to do to use SaaS is have a device connected to the Internet and log in. All else is up to the provider. The applications are run using the provider's infrastructure. To start using PaaS, you would need first to develop a custom application or deploy and modify an open-source software in order to use PaaS tools.

What Is the Difference Between IaaS and PaaS?

IaaS encompasses cloud services related to hardware components, like virtual machines or VMs and scalable storage. PaaS adds to this by offering platforms for building and deploying applications.

One main difference between the two is that you have more control over operating systems if you use IaaS. If you go with PaaS, you will have more flexibility and an easier time navigating the service. Another difference is that IaaS mimics the infrastructure of cloud-based technology. On the other hand, PaaS is a safe haven for developers because it helps them build and deploy custom applications through the cloud.

So, simply put, IaaS is the foundation for building a cloud-based service for content, software, and a website that sells physical items, among other things. PaaS is a platform that allows developers to develop applications without needing to host them.

When to Use PaaS?

  • PaaS is the perfect answer for you if you're a developer working on a project or app with other developers because it can efficiently streamline procedures. It also improves the process's speed and flexibility
  • If you want to build a custom application either on your own or with a team, PaaS is for you. It provides you with all the tools you need for application development and deployment, and all you need to manage are the applications themselves and the data. All else is handled by the provider
  • If you are looking to host your application in a place that offers faster speeds, built-in backups, more extensive scalability, and easier deployment of your applications, PaaS is the place for you. With other hosting types like web hosting, you would have to do additional work like setting up monitoring, alerting, load balancers, deployment scripts, etc., before you can start developing your app. So, if you do not want to do all this additional work and need a superior production environment, PaaS is the better hosting option for you. PaaS has all of this built-in, and it does not require you to manage servers because the provider does this for you. This allows you to focus more on the app itself and on writing code
  • PaaS is an excellent solution for anyone looking for a service that will assist the rapid development and deployment of an app while lowering costs and simplifying problems. PaaS helps developers get their apps faster to the market by handling all the hardware and software and managing servers

Different PaaS Services

  • DBaaS – Database-as-a-Service s a cloud-hosted database that offers storage, computing power, and relational database capabilities with PaaS. DBaaS supports all kinds of databases, including NoSQL, MySQL, etc.
  • IoT Platforms – Internet-of-Things platforms encompass the different things embedded with sensors, software, etc., and are used to connect and exchange data with other devices via the Internet. Some examples are cars, lights, and appliances
  • APIs – Mobile Services or APIs conduct the task you want them to in detail and exactly as described. The most common APIs are SMS APIs which are used for building automated massages into the application you have
  • Push Notification APIs – they are similar to SMS APIs, with the main distinction being that with Push Notification APIs, notifications are sent to browsers and mobile devices, not messages
  • Machine Learning – these platforms enable you to create and apply models to your databases to easier navigate extensive databases. Also, machine learning platforms allow you to scale your computing power according to your needs
  • MWaaS – Malware-as-a-Service offers you tools that connect front-end client demands with back-end functions
  • iPaaS – Integration Platform-as-a-Service encompasses services that integrate workloads and applications that normally don't interoperate

Types of PaaS

  • Public PaaS – most suitable for the public cloud

  • Private PaaS – can work on all types of infrastructures

  • Hybrid PaaS – a mix of public and private PaaS

  • Communications PaaS – allows adding real-time communications on applications

  • Mobile PaaS – used for configuration of mobile applications

  • OpenPaaS – free, open-source platform suitable for all devices


So, to summarize, PaaS is a great solution that offers computing power and infrastructure to manage, share and work with data more efficiently. Also, it's the perfect place for the development and deployment of applications and getting them faster to market.

PaaS delivers platforms to users via a web browser, where the providers take care of all the hardware and software while users focus on the app and the data they create. Thus, if you're looking for a space that'll allow you to create custom applications without having to manage servers by yourself, PaaS is the one!
