14. Drawbacks of Static Provisioning
@dfrnascimento 3
- Wait time for tests in job queue during peak workloads
- Capacity planning for optimal utilisation (app vs cluster)
- Update OS, Docker/Kubelet/Jenkins Agent
- Engineering overhead in maintaining cluster

15. Ephemeral

AWS Fargate
- Container platform managed by AWS
- Scale up & down seamlessly
- Integrated with AWS ecosystems
- 50 CPU/Mem config
- Pay per vCPU / memory
Container Kubernetes

17. - Just-in-time ephemeral cost-efficient compute for application
- Any EC2 instance
- Built-in proactive cost management (on-demand, spot)
- Number of Licenses (nodeless)
- VM Isolation, no restrictions on application packaging
- Compatible with Kubernetes

21. reInvent 2018: Serverless under the hood
@dfrnascimento 10
Serverless FaaS

22. - Avoid provisioning and maintaining server fleet
- Reduce cloud cost and slave license cost
- Zero wait time for any incoming workload
- Serverless engines are quick and easy to implement and integrate into existing workflows
- Complement Lambda
