[go-nuts] go in cloud server
Hello. I'm new to go, i'm looking for a programming language to replace java. I have simple questions 1. is it a good idea to deploy go in cloud server if go is compiled to machine binaries, what can happen if the cloud provider changes the physical server to different processor architecture. 2. does go have embedded relational database management system similar to h2 in java. google gives me key/value pair embedded database any help is appreciated. thank you -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
