Cloud galaxy Case 1 of 7

Holding the Olympic peak without an outage

The problem

Paris 2024 Olympics, Rugby World Cup 2023: when sales open, crowds book a hotel at the same time and traffic explodes within minutes.

The constraint

One minute of downtime means rooms go to someone else.

What I did

01

The wave arrives

Traffic shoots up when sales open.

02

The load is spread

Load balancers distribute visitors across several servers.

03

Servers scale out

New servers start on their own to follow demand.

04

Databases absorb it

The databases take in every booking recorded.

The result

The platforms held through both events. Today, 750 million requests a day.
