Top 9 Best Platform-as-a-Service/PaaS

Platform-as-a-service/PaaS is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. PaaS can be delivered in two ways: as a public cloud service from a provider, where the consumer controls software deployment with minimal configuration options, and the provider provides the networks, servers, storage, OS, middleware, database and other services to host the consumer's application; or as a private service inside the firewall, or as software deployed on a public infrastructure as a service. Here below Top 9 Best Platform-as-a-Service listed; Read on:

Top 9 Best Platform-as-a-Service
