This is my fifth post in the series titled “PaaS Is The Future Of Cloud Services” and I am going to briefly discuss one of the key elements of this PaaS-y future, the APIs. Even though having an API doesn’t make something a platform, APIs are key to the very success of the Platform Services. The successful Platform Services players of the future will be the ones who got their API strategy right. This is the reason I called APIs the oxygen for the PaaS-y future in a recent post about Apigee-Heroku announcement. In this post, I will briefly discuss the role played by APIs in the Platform Services and highlight some of the issues to be considered while developing APIs for platform. Please note that this is by no means exhaustive and feel free to add your thoughts in the comments section below.
