General Billing
There are three main drivers of billing:
● Compute that was used/requested
➔ I want a server with 4 CPUs and 32 GB of RAM
➔ That server was run for 8 hours
● Storage that was used/requested
➔ I want 50 GB of fast disk storage
● Network that was used/requested (only in the outbound direction)
➔ I transferred 20 GB of data out to my office
● Ensure to understand all the aspects of pricing for a service
● Choose the correct sizing of service to optimize costs
● Make use of AWS’ Optimize and Save tools when possible
● Scale up only when needed and make sure to scale back down
➔ Utilize auto-scaling when possible
