Running Databases on EC2

When to do it:

  • You have to run a database or database version that AWS don't support.
  • You have access to the operating system of the database.
  • You have to configure some advanced database settings which aren't available with managed databases.
  • You need a specific OS and Database combination.

Disadvantages:

  • You have to manage EC2 and the Database host, which is just increased admin overhead.
  • You have to backup manually.
  • EC2 is only in one Availability Zone, so it is not very highly available.
  • You are missing out on features from pre-existing AWS database services.
  • There is no seamless scaling.
