Load balancing

Load Balancing or Clustering?

Advantages are:

Resiliance no more single point of failure in the application tier

Session Replication, if a server goes down your session will carry on just by another server node in the cluster.

Disadvantages are:

Complexity - more complexity means more risk of it not working(down more to configuration or human error than the software)
Need more Server resources - more disk , more cpu , more network traffic etc...

Your applications will need to use the clustering services in the container and so they need to be coded to be made 'cluster aware'


Load Balancing is a much simpler setup to implement

Advantages:

Quicker and easier to setup
No need to re-engineer your apps.
