Comment Comment by jacques_chester Since we're calling out OSS alternatives that the author missed, I'll point out Cloud Foundry. It solved the "rolling upgrade" problem years ago.Currently you can run it on AWS, OpenStack or vSphere; Azure and GCE support are being worked in concert with Microsoft and Google respectively.Disclaimer: I work for Pivotal, the company which donates the largest chunk of engineering effort to Cloud Foundry. parent jacques_chester 10 years ago
