8 PaaS to Build and Host Your Modern Applications

This article will talk about the most popular PaaS platforms available to host your modern application.

PaaS (Platform as a Service) is awhere the service providers deliver a platform to the client to develop and host the application. The developers or DevOps use this platform to develop, test, and run the application. The developers can focus on building their application and leave the worries of setting up the platform with the platform service providers.

PaaS helps in the application’s rapid development as developers focus only on code and leaving infrastructure headaches to the provider. There are multiple PaaS platforms out there that you can leverage if you are looking to build your application quickly.

The following are the managed platforms, and to build something in-house, you can explore these software to.

Google App Engine

Google Cloud offers a fully managed serverless platform called, which builds highly scalable applications. You don’t need to look after any server or infrastructure management while using the App Engine to develop your application.

It provides two environment options – standard and flexible.

The standard environment runs your application instances in a sandbox and is preferred when you see a spike in the application traffic and need rapid scaling. The flexible environment runs your application instances inside Docker containers and is preferred when there is a lot of fluctuation in the application traffic. You can also use both the environments together in parallel.

In case you need to scale your application, you can do it with a few clicks and push a button within a minute.

Google Cloud App Engine features:

  • Zero servers and configuration management
  • Cost friendly, pay only for what you use.
  • Provides IAM rules and firewall capabilities to protect your application from security threats
  • Options to build your application in Java, Python, Node.js, Go, Ruby, C#, PHP, or even use your own language runtime.
  • Logging and monitoring feature to keep an eye on the health of your application.
  • Maintain different app versions and create different environments (DEV, TEST, PROD) with ease

Cost wise this platform is very effective. You get 300$ free credit for the first 90 days if you are a new customer to try.

DO App Platform

recently introduced an, which is gaining popularity among developers.

It will automatically take your code from GitHub, build it, and publish it on the cloud. And whenever you update your code in GitHub, it will re-deploy your application over the cloud. It’s called.

How cool is that?

DigitalOcean App Platform features:

  • Provisions and manages OS, infrastructure, dependencies, databases, etc.
  • Manages SSL certificates and protects against DDoS attacks
  • Direct deployment from GitHub repositories
  • Multiple scaling options are very cost-friendly and give your app zero downtime.
  • Supports applications using Python, React, Node.js, Laravel, Ruby, Ruby on Rails, GoLang, Gatsby, Hugo, Dockerfile, static sites, and many more.

You can manage the app platform through the DO dashboard or API. You can get it started with as low as $5 per month. DO offering sounds perfect for small to medium businesses.


is an edge cloud PaaS that easily allows developers and companies to deploy and manage multi-regional containers and applications.

It makes running and hosting global web services simple and affordable. Instead of running your code in a single centralized location, you can now run it in multiple locations simultaneously.

The appfleet PaaS was built to support multiple use-cases, from regular single-region app hosting to globally distributed services. It is a great alternative to shared hosting, managed and unmanaged Kubernetes platforms, Heroku, and even serverless providers.

All you have to do is provide your container or connect your Github repository and select the locations you want to deploy to. The system will handle the rest.

Hosting your web services and applications on the edge results in drastic performance improvement, lower latency, better uptime, and lots of new use-cases and possibilities not previously possible. In part, it’s because appfleet is not limited only to HTTP services like all other PaaS providers. The platform provides complete freedom to run any service over any port, both TCP and UDP.

Example use-cases include but are not limited to global nameservers and DNS hosting, distributed databases, image optimization on the edge, custom CDNs, or even containers running multiple different services on different ports at the same time.

Every application hosted on appfleet automatically gets high-availability with multiple automated checks and failover systems in place with all global traffic intelligently routed to the closest available location.

All users also get access to many other features that simplify container deployments like:

  • Free unlimited and automated HTTPS certificates
  • Zero downtime deployments
  • Automated deployments on Github commits with easy integration with existing CI tools.
  • Local fast SSD caching for better performance
  • Logs and console accessible via the web UI for easier debugging and control
  • Monitoring with detailed statistics about each cluster
  • Automated scaling to handle load spikes without user impact
  • No cold-starts or delays
  • Affordable prices and a pay-as-you-go self-service system

Everyto test things without entering a credit card number.


is an end-to-end PaaS solution for building, running, and scaling your application. It was specially built for continuous deployment and is known for a high-performance cloud platform as a service.

Heroku Platform

is one of the pioneer PaaS providers.

It allows you to focus on delivering solutions and deploying applications, not operations. With Heroku Platform, you can build and deploy functionalities at your fingertips. You can start developing your application immediately. Everything required for the app is already managed and provided by the Heroku Platform. In the world of DevOps, you dev and Heroku ops.

Heroku Platform is amazing as it is developer-centric, app-centric, and production-centric. It gives developers an amazing experience by focusing only on development and keeping mundane/non-development tasks away. It helps developers to make their applications live faster to real users. And finally, it deploys the application in a production environment without any hassle.

You can get it started through their neat dashboard or CLI.

Heroku platform provides you below tools to create your application with ease:

  • Heroku Developer Experience (DX): Support software development approach where developers focus on creating and continuously delivering the applications.
  • Heroku Operational Experience (OpEx): It is used to troubleshoot issues in your application and alert you about the application’s health’s negative trends. It has threshold alerting, autoscaling, and application metrics features.
  • Heroku Runtime: Runs your application in a fully managed and reliable environment called Dyno. These are smart containers inside which your application runs.

The pricing on Heroku depends on your application type. Heroku runs your application inside isolated Linux containers called Dyno.

AWS Elastic Beanstalk

lets you deploy your application, which you might have developed with programming languages like Java, .NET, PHP, Node.js, and many others on familiar servers such as Apache, Nginx, Tomcat. On elastic beanstalk, developers have to upload their applications.

Features like load balancing, auto-scaling, application health monitoring are all handled automatically by AWS.

Elastic Beanstalk simplifies entire app development. You only have to focus on writing code; the rest of the things like monitoring servers, storage, network, and managing virtualization, operating system, databases is managed by AWS, which simplifies the entire process for a developer.

AWS Elastic Beanstalk features:
