Instance Configurations

We cover the options available when configuring an EC2 instance in the web console.

Some of the options we cover:

1. Spot Instances - Save money using Spot instances, if your applications and infrastructure are fault-tolerant.
2. Networks/VPC - We cover this in the VPC Basics course
3. Placement Groups to determine how EC2 instances are created within AWS's physical infrastructure
4. Domain join directory - Use AWS Directory Services, essentially AWS's Active Directory
5. IAM Roles - We mention this but don't cover it much, we'll be covering that in other courses
6. CPU Options - Often used if serving software whose licenses charge per CPU core or thread.
7. Behaviors - there's a few general options here, mostly self-explanatory
   • Monitoring in CloudWatch samples every 5 minutes by default, however "enabling monitoring" will sample every 1 minute
   • EC2 Tenancy
   • Elastic Inference
8. Credit Specification
9. File systems (NFS)
10. Enclave
11. EC2 metadata/userdata
