Container Orchestration is a series of online sessions to discuss:

  1. Why containerized orchestration - experiential case studies of patterns and anti-patterns.
  2. Tools and tooling - why and how.
  3. Deployment and monitoring; troubleshooting.
  4. Security.

Sessions on Containerized Orchestration will be held as:

  1. Standalone talks
  2. Birds of Feather (BOF) sessions
  3. Quarterly (online) MiniConfs

Submit a topic for someone to conduct a session; or submit ideas based on your experience with container orchestration.

Migrating from traditional EC2-like infra to Kubernetes

Submitted Apr 13, 2020

This talk is inspired by our journey at Zapier to migrate our app infrastructure from traditional AWS EC2, terraform, Ansible based workflow to Kubernetes. The challenges we faced during this journey, the solutions, and finally the rewards. I strongly believe that this talk will help many people who are in a similar position we were when we started this journey. They want to use Kubernetes to speed up application deployments, pack applications densely, etc., but are skeptical to take the plunge from traditional EC2 based deployment models to Kubernetes.

Outline

  • State of things at Zapier, pre Kubernetes
  • Challenges faced
  • How Kubernetes promised to solve the problems?
  • Looking for a stable Kuberenetes distribution
  • Setting up Kuberenetes platform: cert-manager, external-dns, ingress, etc.
  • Manage Kubernetes artifacts
  • Testing the waters: running staging envs, non critical internal apps, etc.
  • Disaster management and migration in Kubernetes
  • How to load balance apps between previous infrastructure and Kuberenetes?
  • Start running Zapier monoliths in k8s to handle a little of prod traffic
  • Migrate role by role
  • 90% of Zapier running on Kubernetes
  • Time to run stateful apps in Kubernetes
  • Always launch multiple Kuberentes clusters in production and load balance apps for HA
  • Monitoring
  • Where are my UDP packets?
  • Beware of noisy neighbours. Do proper resource planning and setting for apps.
  • Continuous deployment
  • Current state of things. Cost savings, deployment times, rollback times, etc.
  • More challenges. We love it
  • The future ahead

Requirements

  • Understanding of AWS EC2 like infrastructure and deployment models with Ansible, Terraform, etc.
  • Some knowledge about CI/CD
  • Basic understanding of Kubernetes
