The best thing about bluemix is it provides you with many services ranging from server management all way down to mobile development. I am very happy using Bluemix as they are always open for suggestions or questions which makes me feel good because this platform needs constant improvement if we want customers happiness. Currently there isn't anything i dislike but maybe more features in future could be added like support for native applications instead only web apps would be nice but still not bad at all. We can now develop an app without any coding knowledge just by uploading in to cloud so my previous worries were solved right away!
