1. Cloud Native DevOps / SRE ? DEPLOYMENT STRATEGIES There was never a time when the world began, because it goes round and round like a circle, and there is no place on a circle where it begins. - Alan Watts
2. Ruwan Ranganath Sr. Software Engineer - Devops @ Apigate Docker Community Lead devops.lk & foss.lk Mozilla Community Lead @ruwan_ranganath /ruwan-ranganath
3. Era of Cloud DevOps || SRE Containers & Orchestration Order of Cloud Native World
4. Cloud Based Orchestration Containerized Dynamically managed automation Distributed systems Cloud Native DevOps
5. Nobody Wants to Understand DevOps John Willis - CAMS sharing measurement automation, culture Brian Dawson - trinity: process and practice People & culture tools and technology
6. The Business Advantage Container & Orchestra Infrastructure as a Service Works on My Machine, Ops Problem now Era Buying Time of SaaS.
7. Infrastructure as a Code Resources need to be provisioned, networked, deployed, configured, kept up to date with security patches, monitored, managed, and so on.
8. provider "google" { credentials = "${file("CREDENTIALS_FILE.json")}" project = "gcp-project-id" region = "us-west1" } resource "google_compute_instance" "default" { name = "flask-vm-${random_id.instance_id.hex}" machine_type = "f1-micro" zone = "us-west1-a" boot_disk { initialize_params { image = "debian-cloud/debian-9" } }

15. Containerize the product FROM ubuntu RUN apt-get update RUN apt-get install –y apache2 RUN apt-get install –y apache2-utils RUN apt-get clean EXPOSE 80 CMD [“apache2ctl”, “-D”, “FOREGROUND”]
16. Orchestration
17. Container Orchestration Making much easier way ! A piece of software designed to join together many different machines into a cluster: container orchestrator Managing the resources available and assigning workloads where they can most efficiently be run Scheduling Joining multiple physical or virtual servers into a unified, reliable, fault-tolerant, apparently seamless group cluster management Well you already know ! Kubernetes / ECS / Swarm
18. Traditional deployment strategy, We all do this ? Highlander 01 Breaking small portion from a production always feels good. Raise your hand ! Canary 02 Safe way to break everything step by step 101. Seriously ! How careful you are ? Rolling 03 I’m not sure you’ll notice green is blue and blue is green here ? Better way to blame other guy xD Blue / Green 04 Where are we today ?

20. Canary Deployment
21. Rolling Deployment strategy: type: Rolling rollingParams: updatePeriodSeconds: 1 intervalSeconds: 1 timeoutSeconds: 120 maxSurge: "20%" maxUnavailable: "10%" pre: {} post: {}
22. Multi-group deployments
23. Blue / Green Deployment
24. Canary with Two Groups
25. Rolling Deploy with two groups
26. • Shadow Deployment • A/B Testing • Feature toggle

28. Deploy to last long ! Deployment Checklist Continuous Integration
29. Deploy to last long ! Continuous Deploy / Delivery Standard operating environments (SOEs)
30. Deploy to last long ! Build Automation Configuration Management
31. Deploy to last long ! Communication Channel Alerting & Engaging Process Or RollBack !
32. Post-Deployment Monitoring Let L1 Guy Sleep ! No Logs Stop Notify
33. An APM / Error Monitoring tools also creates a shared visibility of all the post-deployment issues among Operations / DevOps teams and developers. This shared understanding allows the teams to be more collaborative and responsive.
