Can there be what other to caché that's as performant and scalable but free ?and when feasible for .Internet ?

I understand that this can be a comment, however i still will write it as being a solution.

Why would you like free one with your serious demands? Either you:

  1. Don't actually need so that it is so trendy, and may use simpler one.
  2. Operate in large company / for large company. Then you definitely should have the ability to purchase it, either place it in needs section inside your contract, or inform your boss / financial people who it ought to be. If you would like to save money then its strange way. Free results in insufficient support. How would you solve production issues fast? Be sure to bring it up.
