Maybe your boss wants you to migrate your application to PaaS, but you are unsure of what that involves or which cloud platform to use for development and management.

If you have questions about how important is a Platform as a Service, for the next decade and want to learn more about its benefits, features, and available providers, you have come to the right place. We will provide a brief introduction to what is PaaS and highlight PaaS architecture in cloud computing, benefits of PaaS in cloud computing, features of PaaS, top PaaS providers, PaaS providers comparison, disadvantages of PaaS and benefits of PaaS for small business.

From now on, the focus will be exclusively on the Platform as a Service (PaaS) model.

What is PaaS?

You can create, operate and manage online applications and services using Platform as a Service (PaaS) model without having to take care of your own infrastructure and tools.

In a PaaS model, a user pays for access to a set of resources and tools provided by a cloud provider (Google Cloud Platform, Microsoft Azure, AWS) on an as-needed basis. These resources may include hardware, software, infrastructure and other tools and resources required for application development, testing and deployment.

You do not need to worry about managing or maintaining these resources yourself, as this is taken care of by the PaaS provider. Simply put, it is a Managed Service. You do not install or maintain the operating system, middleware, etc. You just run your code on it. Deploy your product to the respected cloud provider, get the connection strings and connect to it from your application and run your code.

PaaS architecture in cloud computing

In a PaaS architecture, the cloud provider manages the infrastructure, such as servers, storage, networks. This infrastructure is usually virtualized and accessed over the Internet. Take care of the hardware for you and support you if something happens at the software level that is not related to your own code or data.

PaaS cloud provider also offers a range of tools and resources for developers to use, such as integrated development environments (IDEs), version control systems, testing tools.

PaaS architecture in cloud computing also highly scalable, allowing applications to easily adapt to changing demand and traffic levels, since they let companies to adjust your resources scale up or down as needed.

Additionally, PaaS systems can reduce costs for enterprises because they only charge for resources that are used, which saves both money and time for businesses.

Benefits of paas in cloud computing

  1. Pay-as-you-go basis of PaaS architectures saves costs, avoiding companies the start-up and maintenance costs of their own infrastructure.
  2. PaaS architectures offer scalability, easy to scale your resources up or down to meet changing demand or adapt based on your workload.
  3. Time can be saved by using PaaS architectures, as underlying infrastructure is abstracted away and need for internal management is eliminated. This allows to focus on developing and deploying your applications.
  4. Security is enhanced by integrated security measures and management by the cloud provider in PaaS architectures, reducing the need for organizations to maintain their own security infrastructure.
  5. Reduced maintenance with less downtime take care of maintenance and updates, patching and upgrading your infrastructure. Save your time and resources, and ensure that your applications are always running on the latest and most secure technology.
  6. Automated backups, based on the backup retention policy you have for resources, are saving your data, and helpful for disaster recovery scenarios.
  7. Easy to embed other third party tools, maybe it is already built-in with or deploy it from your end, and cloud provider will have a large number of resources available so it is easier to integrate.

Useful for companies whose resource needs are constantly changing or who need to respond with flexibility to changing market conditions.

Features of PaaS

In the following list we will highlight the features of PaaS, and get into the details.

  1. Dynamic resource allocation
  2. Ready-to-use infrastructure
  3. One-stop development platform or integrated development environment (IDE)
  4. Customization options
  5. Flexible pricing model
  6. Shared infrastructure
  7. Monitoring and analytics
  8. Security
  • Dynamic resource allocation: Automatically adjust the resources (e.g., CPU, memory) allocated to your application based on demand, which can help you optimize cost, performance, save your time and resources.

    When you develop your resource in cloud provider offer this option to enable them, and the idea behind this to not let your application stuck in case of high traffic or consumed occurs, so your application is ready to handle that, and you will be charged based on the usage, so don’t worry, if you have enabled it, it does not mean that they will start charging you.
  • Ready-to-use infrastructure: A fully-configured infrastructure that includes all the necessary components (e.g., operating systems, programming languages, databases) to run your application, saving you time and effort in setting up the environment.
  • One-stop development platform or integrated development environment (IDE): Includes a comprehensive development environment that enables developers to create, test, and deploy applications all within the same platform, streamlining the development process.
  • Customization options: Allows you to customize your development environment to fit the specific requirements of your application, such as selecting preferred programming languages databases or region where you want to host it.
  • Flexible pricing model: Offers a pay-as-you-go pricing model, which means you only pay for the resources you use, rather than upfront costs for infrastructure.
  • Shared infrastructure: Involves a multi-tenancy model, where multiple customers utilize the same infrastructure. Help lower costs and increase efficiency.
  • Monitoring and analytics: Provides monitoring and analytics metrics to help you track the performance of your applications and identify potential issues.
  • Security: Cloud providers have security measures in place, such as firewalls, encryption, and authentication, to protect your applications and data.

Top PaaS providers

  1. Google App Engine: Google enables developers to build and deploy applications on the same infrastructure used by Google’s own applications. It is a good option for developers who want a fully-managed platform that can handle high traffic and scale automatically.
  2. Amazon Web Services (AWS) Elastic Beanstalk: Amazon Web Services allows developers to swiftly deploy and operate applications in the cloud. Suitable choice for developers seeking a straightforward, scalable platform for application deployment.
  3. Microsoft Azure App Service: Microsoft Azure enables developers to build, deploy, and scale web, mobile, and API applications. It is a suitable choice for developers seeking a platform that integrates with other Azure services and supports a variety of programming languages and frameworks.
  4. Heroku: Same like Elastic Beanstalk, but if you’re looking for user-friendly platform, and this is your option.
  5. Red Hat OpenShift: Red Hat that enables developers to build, deploy, and manage containerized applications. It is a suitable choice for developers seeking a platform that supports container-based deployment and integrates with other Red Hat technologies.

PaaS providers comparison

Difference between these PaaS platform, Google App Engine is based on the same infrastructure as Google applications, while Elastic Beanstalk allows you to deploy applications on top of the AWS infrastructure. App Engine supports a limited number of programming languages, while Elastic Beanstalk supports a wider range of languages.

Google App Engine uses a fully managed deployment model, which means that Google handles the infrastructure and maintenance for you. Elastic Beanstalk allows you to choose between a fully managed or self-managed deployment model.

Google App Engine charges for resources used, while Elastic Beanstalk charges based on the resources used and the length of time they are used.

Comparing PaaS (platform as a service) providers can be a complex task, as there are many factors to consider and different providers may excel in different areas. Some key points to consider when comparing PaaS providers are:

  • Infrastructure: Does the cloud provider have a reliable, high-quality infrastructure, and how does it compare with other providers in terms of performance and scalability?
  • Language support: Does the cloud provider support the programming languages and frameworks you need?
  • Deployment model: Does the cloud provider offer a fully managed or self-managed deployment model, and how much control does it have over the underlying infrastructure?
  • Integration with other services: Does the cloud provider offer integration with other tools and services you use?
  • Pricing: What is the cloud provider’s pricing model, and is it cost-effective for your needs?

It is important to carefully evaluate the features and capabilities of each vendor to determine which one best fits your needs. It may also be helpful to test different vendors using a small project before making a final decision.

Disadvantages of PaaS

  • Loss of control: You may have less control over the hardware, software and infrastructure provided by the PaaS provider.
  • Higher costs: PaaS model can be more expensive for companies with higher usage or specialized needs.
  • Limited customization: PaaS architecture may offer less customization compared to other cloud computing models, such as Infrastructure as a Service (IaaS).
  • Vendor lock-in: You may become dependent on a specific PaaS vendor and may face challenges if you decide to switch to a different vendor in the future.
  • Security issues: PaaS architecture may offer less control over security measures compared to other models, such as IaaS, which can be a concern for companies with strict security requirements.
