AWS UG DXB 2021 container series- IV

https://www.meetup.com/AWS-Dubai/events/280723703/

In this session, we will explore the popular workload manager and scheduler Kubernetes. Amazon managed kubernetes service, Elastic Container Service for Kubernetes (Amazon EKS) takes care of the heavy-lifting and lets one focus on managing the containerized workloads. EKS, however, still gives you the flexibility and choice where to run, and how to efficiently run your data-plane that hosts your workloads. In this session, we cover what you need to know to get your application up and running with Kubernetes on AWS. We show how Amazon EKS makes deploying Kubernetes on AWS simple and scalable.

11. Three vouchers to giveaway
12. • Standardized packaging for software and dependencies • Isolate apps from each other • Share the same host OS kernel • Utilizes Linux Kernel features (e.g. namespace, cgroups, apparmor, selinux) • Microsoft have Windows Native Containers • Lightweight application virtualization • Consolidate 100s of applications per host compared to 10s per vm Review: containers? Build, distribute, and run applications almost anywhere

14. The new sprawl: Containers https://twitter.com/forrestbrazeal/status/1400639759215640577 https://www.lastweekinaws.com/blog/the-17-ways-to-run-containers-on-aws/ https://www.lastweekinaws.com/blog/17-more-ways-to-run-containers-on-aws/
15. Everything fails, all the time. AWS CTO @Werner
16. What Is Kubernetes? • Greek for "helmsman", • The kernel of distributed systems • Linux of the cloud! • A platform and container orchestration tool for automating deployment, scaling, and operations of application containers. • Kubernetes supports Docker, Containerd, CRI-O, Kata containers (formerly clear and hyper) and Virtlet among others • History of over 15 years from Google Borg, +7 years since its OSS inception

23. Kubernetes Architecture Overview Source: Introduction to Kubernetes
24. Kubernetes’ High-Level Architecture Overview Source: https://www.weave.works/blog/what-does-production-ready-really-mean-for-a-kubernetes-cluster
25. Kubernetes’ High-Level Architecture Overview
28. EKS • Certified Kubernetes distribution • OSS components available as EKS-Distribution • Can be run in Cloud or on-prem • Integrates well with AWS services for AWS customers • Enables Hybrid, and multi cloud workloads • High availability, security, resilience, and Fault tolerance "across AZs" • Undifferentiated heavy lifting
29. Why EKS? - CNCF certified distribution - can enable Hybrid, and multi cloud workloads - Integrates well with AWS managed services model - HA and Fault tolerance "across AZs" - Fully managed control plane ( self-healing, upgrades, patching)

36. Container OS Purpose built operating system Optimized for running containers Minimal Linux distribution No-Ops maintenance Cost effective Immutable Automation in mind Security in mind API driven AWS Bottlerocket
38. Exploration time
39. Why Fargate? • Serverless wins: Focus on application • Scalability out of the box: clusters scales with application • Reduce operations and day-2 overhead: • Updates and patching for infra and cluster • Still need to take care of image updates • Better security isolation • Cost efficient
