9. © 2019, Amazon Web Services, Inc. or its Affiliates. All rights reserved. Amazon Confidential EC2 based clusters require work! Patching and Upgrading OS, agents, etc. Scaling the number of instances in the cluster for optimal utilization according to the number of containers you need to run ECS Agent Docker Agent OS EC2 Instance

30. Showpad ❤ Kubernetes Kubernetes v1.2 Production usage Prepare Staging Immutable Kubernetes Future ... April 2016 Summer 2016 Q1 2017 Q1 2019 +2500 containers 2018 2019-
31. EKS … but we don’t want to maintain every cluster ❤
32. Why? Allows us to focus on core Unifies tooling and procedures We can easily swap when needed
33. Spot nodes Nov 2018 ASG with multiple instance types • Mix instance types in a ASG • Mix spot & on-demand • Baselines for on-demand Perfect for (our) Kubernetes nodes
34. Kubernetes Spot Node lifecycle K8S requires additional node Spot node is added to the cluster We cordon / drain the node (2 minutes) ASG is increased Termination event triggers If needed, ASG is increased again Node is terminated
35. Why? Low engineering effort Cost reduction Chaos engineering
36. Monoscaler Monitors input channels (SQS, classic AMQP) Scaling defini:ons in the deployment Talks to Kubernetes API server to create addi:onal jobs
37. Why? Scale to zero One solution for cloud and legacy Control our scaling 100% Cost reduction
