Resource configuration

Facilitate current instance types

• those are usually more cost-efficient

Default to inexpensive parameters

• many tests do not require production oriented environments (e.g. multi-az)

 Facilitate EC2 spot instances ('use spot')

 | 

•  significant savings (~75%)

•  meanwhile easy to use

  • See https://www.infoq.com/news/2018/01/amazon-ec2-spot-streamlining

•  BBS NFS instance pending (non-trivial)

  •  single EC2 instance is not HA!

Resource utilization

Reuse/Disable optional components

• e.g. NAT gateways and bastion hosts

 Stop cluster during off-hours ('cold standby')

 |  

•  significant savings (~75%)

•  RDS instances pending

  •  How to mitigate the automatic weekly RDS instance restarts 

• BBS NFS instance pending

Terminate cluster during off-hours (fully automated backup/restore)

• savings potential depends on MTTR goals (non-trivial)
