2017 Server Upgrades

Architecture

The key architecture change for 2017 is to remove our reliance on a single vendor for hardware and network support. With this upgrade, we will now have servers provided by both Rackspace and Amazon. Likewise, network and DNS services will also be provided by these two companies. This eliminates a "single point of failure" risk is several key areas.

Notable Software Upgrades

  • Operating System: Linux 7.11 to Linux 8.8
  • Web Server: Apache 2.2  to Apache 2.4
  • Database: MySQL 5.6 to MySQL 5.7
  • Language: PHP 5.6 to PHP 7.1 (a "PHP 6" was never released)
  • Proxy Server: HAProxy 1.5 to HAProxy 1.7
