The simplicity of using this platform was one thing I liked most about it. This helped me get started quickly without any technical knowledge or expertise required from my side. Also its UI makes working easy even if you have no prior experience in cloud environments. We could not able to manage our own clusters which were hosted by third party vendors like HPE etc., but we are now managing them all via the same interface as well. But what's more important than that, there has been almost zero downtime so far! Nothing at all really!! So nothing much to dislike here apart form some minor glitches when dealing with HA configurations. If your looking into self hosting then go ahead otherwise use 3rd parties such as AWS EC2 instances instead. Self Hosting applications within your private network environment.
