With Platform as a Service (PaaS), applications are hosted by a complete computing solution stack in the cloud. The subscriber does not need to worry about infrastructure or hosting environment administration. PaaS products continue to be rapidly accepted and consumed by subscribers.
PaaS allows an enterprise to do more with limited resources. However, careful choices still need to be made to ensure that deployments are not constrained by poor scalability, lack of interoperability, or vendor lock-in. A properly architected cloud application can be ported to multiple providers to allow for global reach, a clearer growth path, and future flexibility.
Finding the right PaaS product is crucial to successful adoption and deployment. We have developed the ODCA PaaS Interoperability Usage Model to guide RFP creation for the PaaS solutions you are looking for.
The choice between a PaaS and an Infrastructure as a Service (IaaS) solution can be made clear with the right information. They both can be a part of the long-term strategy of the enterprise. Read more about them in the ODCA Developing Cloud-Capable Applications White Paper.
