Developement

My name is Kris. I'm one of the 2 web developper for the e-commerce website: [login to view URL] (formerly [login to view URL]). We're doing a complete reset of our website with vsphere. We're actually almost done and ready to go live, but because we're 2 web developper, specialist in PHP, we need some recommendation from an actual sysadmin who knows a lot about vsphere and network management and security. The current setup is: A dedicated cloud server hosting vsphere 6.0 On vsphere, we have 5 vm running: - vm1 - main web server hosting a symfony2 website for 5 domains - vm2 - mysql server - vm3 - mail server - vm4 - dev server, which is a clone of the main server - vm5 - mini server All five servers are running Ubuntu 14.04. We're looking for some help to improve the security of the servers, the reliability of the mail server and the general performances (especially for the mysql server and the main web server). Kris E
