I have an app launched on AWS ELB at the moment. AWS automatically enables an application load balancer which is a significant cost driver to my application. I only have 20 users at the moment, so the load on my application is quite low. When is a good time to enable load balancing?

CodePudding user response：

Use single instance environment in Elastic Beanstalk if you don't want to use load balancer yet.

Quote:

Single-instance environment

A single-instance environment contains one Amazon EC2 instance with an Elastic IP address. A single-instance environment doesn't have a load balancer, which can help you reduce costs compared to a load-balanced, scalable environment. Although a single-instance environment does use the Amazon EC2 Auto Scaling service, settings for the minimum number of instances, maximum number of instances, and desired capacity are all set to 1. Consequently, new instances are not started to accommodate increasing load on your application.

Use a single-instance environment if you expect your production application to have low traffic or if you are doing remote development. If you're not sure which environment type to select, you can pick one and, if required, you can switch the environment type later. For more information, see Changing environment type.
