What are monoliths, what are microservices, how do containers fit into the picture, and how do I do this all in production? In this webinar, we will explore the reasoning and concepts behind microservices and how you can transform monolithic apps into microservices. We will discuss how containers simplify building microservices-based applications, and we will walk through a number of patterns used by our customers to run their microservices platforms. We will cover: - 101 introduction to container solutions and microservices - Key microservices concepts and common patterns - Why you should use containers and the benefits of using Amazon ECS Presented by Daniel Hobson, Associate Solutions Architect, Amazon Web Services. https://aws.amazon.com/webinars/anz-webinar-series/

14. What is EC2 Container Service
Easy Cluster
Management
Flexible
Scheduling
Integrated and
extensible
Performance at
ScaleSecurity
14

15. Cluster Management Made Easy
• No cluster software to install and manage
• Manages cluster state
• Manages containers
• Control and monitoring
• Scale from one to tens of thousands of containers
15

16. Flexible Scheduling
• Optimal instance placement
• Integrate custom or 3rd party scheduler
16

17. Integrated and Extensible
• Integrated with AWS Services
• IAM and Security
• Elastic Load Balancers
• More
• Extensible through powerful APIs
• Use your own scheduler
• Connect with existing software delivery process
17

18. Security
• Your EC2 instances
• VPC Security
• Security Group and IAM roles support
18

19. Performance at Scale
• Building block for distributed applications
• Coordinates and automates container
deployment
• Launch thousands of containers in seconds
19

20. Common Use Cases
• Distributed Applications / Microservices
• Batch /ETL Jobs
• CI/CD
20

21. ECS Components
• Clusters
• Container Instances
• Containers
• Service
• Task Definition
• Docker Daemon
21

22. ECS Clusters
22
• ECS Instances
• Multiple Availability Zones
• Dynamically Scalable

23. Container Instances
• Amazon EC2 Instances
• Docker daemon
• Amazon ECS Agent.
https://github.com/aws/amazon-ecs-agent
23

24. Task Definition
• Container Definitions
• CPU/Memory
• Links
• Volumes
24

25. Tasks
25
• Single Unit of Work
• Run on Instances
• Can be multiple containers

26. Service
• Keeps a desired count of Tasks
• Can run behind load balancer
• Task Placement (AZ Balanced)
26

27. EC2 Container Registry (ECR)
Fully Managed Secure Highly Available Simplified Workflow
27

28. Example Workflow
I have a Docker image,
and I want to run the
image on a cluster
28

29. Example Workflow
Push Image(s) Amazon ECR
29

30. Example Workflow
Create Task Definition
Declare resource
requirements
Amazon ECS
30

31. Example Workflow
Run Instances EC2
Use custom AMI with Docker
support and ECS Agent. Instances
will register with the cluster.
31

32. Example Workflow
Run Task or Create Service
Using the task
definition created
above
Amazon ECS
32

33. Demo - Let’s Take a Look
• Look at Dockerhub
• Build a Dockerfile for nginx
• ECR
• Create a repository
• Push the image
• ECS
• Create a Cluster
• Create a Task Definition
• Launch a Task
• Create a Service
• Stop tasks to check resiliency
• Create A load Balancer
