Session Management in an Autoscaling Environment

Problem Statement

User sessions in J2EE and LAMP stacks have traditionally been handled in memory by the application server handling the user request. Because of that, load balancers have been configured to use sticky sessions. By sticky sessions we mean that once the user has visited the site, they will be assigned an app server and will return to that server for subsequent requests. The load balancers typically handle that by referencing the users session cookie.

Elastic cloud environments differ from traditional server configurations in that they have a variable number of servers based on traffic loads whereas traditional configurations had a fixed number of servers. When traffic volumes decline it is necessary to vaporize servers. In doing so, we would lose user sessions (essentially forcing a logout) unless we come up with a new strategy for session management.

A new approach

After much research, it is clear that the best

	// Generates a strong password of N length containing at least one lower case letter,
	// one uppercase letter, one digit, and one special character. The remaining characters
	// in the password are chosen at random from those four sets.
	//
	// The available characters in each set are user friendly - there are no ambiguous
	// characters such as i, l, 1, o, 0, etc. This, coupled with the $add_dashes option,
	// makes it much easier for users to manually type or speak their passwords.
