From AWS article on Best Practices in Evaluating Elastic Load Balancing, section Pre-Warming the Load Balancer:
"In certain scenarios, such as when flash traffic is expected, or in the case where a load test cannot be configured to gradually increase traffic, we recommend that you contact us to have your load balancer "pre-warmed". We will then configure the load balancer to have the appropriate level of capacity based on the traffic that you expect. We will need to know the start and end dates of your tests or expected flash traffic, the expected request rate per second and the total size of the typical request/response that you will be testing."
Edit: This means ELB could not deal with sudden spikes of traffic.
- nikolay 11y agoAlthough we've used to call support and request a higher capacity ELBs (you can't get this automatically), recently we stopped doing it recently and handle spikes from 1,000 to 100,000 concurrent users within a couple of minutes without a sweat. By the way, many people are unaware, but CloudFront distributions also need to be upgrade to handle spikes similarly to ELBs.
