Infoworld published the results of real-world tests on seven different platform-as-a-service (PaaS) vendors. Of the seven, CloudBees and Cloud Foundry came out on top.
A PaaS is supposed to manage your app deployment, set up your virtual infrastructure and app servers, and allow you to provision the particular instances of VMs that you need to run your apps. Infoworld looked at Amazon, Google’s App Engine, Microsoft’s Azure, VMware’s Cloud Foundry, Salesforce’s Heroku, CloudBees, and Red Hat Open Shift. I found Infoworld’s review of particular interest because there are so few comparative reviews of PaaS products.
