There are other factors to include as well. Monitoring and management are quite important, and this is where environments like the JVM and .NET do a very good job. Ecosystem maturity, availability of mature and quality libraries, availability of good quality documentation, community size and support. I find these guidelines to be a good starting point when deciding what stack to go with, as opposed to what the latest hyped languages are. We've already seen people go with hype, only to realize and backtrack their decision to use a more mature and well established language and ecosystem.
