PaaS, or Platform as a Service, provides a platform for your development team to focus on building applications without them having to manage the servers, storage, and networking resources. It provides a simplified development experience, improved application performance, faster time-to-market, and more scalable applications.

I reviewed the top PaaS services, so you don’t have to. In my evaluation, you’ll find the details of each solution, why I included them, information on pricing and trials, and helpful screenshots.

What Are PaaS Services?

Platform as a Service (PaaS) provides a cloud-based environment where businesses can build, test, deploy, manage, and update their web applications. Some functionalities include pre-built templates for app development, automatic scaling and load balancing, and pay-per-use pricing models for cost optimization.

PaaS tools allow businesses to manage the complete application lifecycle within one integrated environment and not worry about handling infrastructure like storage or servers, software licenses, middleware, container tools, and other development tools.
