Load Balancing
A load balancer sits in front of your application and spreads requests across more than one server. It also allows a release without logging anyone out. The single server you have now is measured first.
What the balancer has to get right
A second server introduces problems that a single machine never had. These are the ones that catch teams out.
Releases without a maintenance window
A balancer removes the need to schedule downtime for ordinary updates.
When it is not the answer
Some businesses add a second server while the first sits idle. Measurement usually points elsewhere.
Frequently asked questions
Do we need load balancing or a bigger server?
It depends on the measurements. A larger machine is simpler and often cheaper until protection from one server failing matters. Once continuity matters more than cost, two smaller servers behind a balancer suit better.
Can this work on our existing hosting?
It depends on the provider. Cloud platforms offer a balancer as a service, while shared hosting generally cannot support one and would need a move first. Which case applies is confirmed before work starts.
Will adding a second server make the site faster?
Not for a single visitor. It helps when many people arrive together, and it keeps the site running when one machine fails. A page that is slow when nobody else is on it needs a fix elsewhere.
