We already know that IaaS (Infrastructure as a Service) is a service model of cloud computing where the user outsources the resources used to support operations. Resources including storage, hardware, servers and networking parts. Cost is typically on a per-user basis. Unlike colocation services, in IaaS the service provider owns the equipment and responsible for running and maintaining it. The client typically installs the required software and run the applications.
PaaS (Platform as a Service) are mostly for helping the developer to speed up the development phase, save money and most important feature of PaaS is avoidance of setting up configurations and managing many technical things of backend. Many of the Platform as a service (PaaS) automates the configuration, deployment and management of applications in the cloud. Heroku is one of the oldest PaaS and we published lot of guides in the past. OpenShift is another PaaS on which we have some guides on this website. Among the remaining, there is IBM BlueMix (which is now within the IBM Cloud entity), we do have some guides on IBM BlueMix. Rest is like Google App Engine (we do have fewer guides as well), CloudFoundry etc. We never tested much more PaaS outside the mentioned. Azure, Amazon also has PaaS.
A Perfect PaaS platform should take care of the following points:
- As real time as like any IaaS
- High Availability
- Git support
- Command line tools
- Multiple Database options
- Data backup option
- Wider languages and framework support
- Support of templates
- Good number of sample projects on GitHub
- Support for deployment on public or private cloud
- Good uptime
- Support for enterprise needs (such as cluster management, user identity management)
- Secure tunneling support
- Support for port management
- Good documentation
- Good support
- Cheap with a free usage tier
Unfortunately, finding a good PaaS platform even after spending money is not that easy. Instead of seeking an allrounder best PaaS, it is better to find your goal related best PaaS.
