1. Kubernetes on AWS (using Amazon EKS)
AKASH AGRAWAL | JULY’27 2019

2. Agenda
● Containers & Kubernetes - Overview
● Running Containerized Applications on AWS Cloud
● EKS Overview / Architecture / Benefits
● EKS - Day-1 Job
● EKS - Day-2 Job

3. About Me
● having 11+ years of experience in IT Industry
● I worked for various clients like Sabre Travel Technologies / Citi Bank /
Goldman Sachs / L&T InfoTech etc.
● From last couple of years, I work as Independent Consultant:
○ I work with different Startups, helping them to design/improve
solutions around Cloud & Kubernetes EcoSystem (as Technical
Adviser)
○ Trainer around Cloud & Kubernetes EcoSystem

4. Containers & Kubernetes -
Overview

5. Containers
● Package your Application & it’s Dependencies
● Container Runtimes: Docker / Rkt etc.
● Focused around Build / Ship / Run
○ Build: build container images (snapshots) on your local laptop
manually or automate it through CI/CD pipeline
○ Ship: ship it through the container registry (ECR/DockerHub etc.)
○ Run: run it anywhere cloud/on-prem etc.

6. Kubernetes
● Kubernetes is an Open Source system for Container Orchestration
(Deployment / Management / Scaling)
● Focused Around:
○ Scheduling
○ Scaling (Manual / Auto)
○ Self Healing / Auto Repairing
○ ...
● Components:
○ Control Plane Components
○ Data Plane Components

9. Running Containerized
Applications on AWS

10. ● ECS
● Kubernetes
○ Kubernetes - Hard Way Approach
○ Kops
○ EKS

11. EKS Overview / Architecture /
Benefits

12. ● EKS (Elastic Kubernetes Service)
● Managed Kubernetes Service on AWS Cloud
● EKS Benefits:
○ No Control Plane to manage (AWS will take care of that):
■ Control Plane HA (in multiple AZs)
■ Auto Repairing / Patching of Control Plane Nodes
○ ...

15. ● EKS Benefits:
○ ...
○ Certified Kubernetes Conformant
○ EKS optimized AMIs (also with GPU support)
○ Spot Instances support available
○ Integration:
■ Amazon ECR (for Container Registry)
■ Load Balancing Support (for CLB, NLB, ALB)
■ Authentication & Authorization (through AWS IAM, Kubernetes RBAC)
■ Clean Network Isolation (through VPC/Subnets etc.)
■ Others: Logging/Monitoring (AWS Cloud Watch/Trail), Service Mesh
(AWS App Mesh) etc.

16. EKS - Day 1 Job

17. Source: https://aws.amazon.com/eks/

18. ● Using CLI (on client/laptop)
○ Install AWS CLI (on client/laptop)
○ Connect it using AWS Access Key ID / Secret Access Key (on client/laptop)
○ Install eksctl
○ Install kubectl
○ follow the steps:
■ https://eksctl.io/usage/creating-and-managing-clusters/
OR
■ https://docs.aws.amazon.com/eks/latest/userguide/getting-started-eksctl
.html

19. ● eksctl command will something look like:
eksctl create cluster
--name prod
--version 1.13
--nodegroup-name standard-workers
--node-type t3.medium
--nodes 3
--nodes-min 1
--nodes-max 4
--node-ami auto

20. ● play around different eksctl capabilities:
○ https://eksctl.io/
● try the same through AWS console:
○ https://docs.aws.amazon.com/eks/latest/userguide/getting-started-console.ht
ml

21. EKS - Day-2 Job

22. ● Go to eksworkshop & look for your use case:
○ https://eksworkshop.com/
● Explore different Integrations e.g.:
○ MicroService Architecture
○ Service Mesh setup : with Istio/AWS App Mesh
○ DevOps:
■ IAC : CloudFormation / Terraform
■ CM : Ansible
■ CI/CD Pipeline : AWS Code Pipeline etc.

23. ● Explore EKS SLA
○ https://aws.amazon.com/eks/sla/
● Explore EKS in scope by Compliance Program
○ https://aws.amazon.com/compliance/services-in-scope/
