hard📝 Best Practice Q15 of 15

AWS - ECS and Fargate

AUse only AWS Lambda functions without ECS clusters

BCreate multiple ECS clusters, each with one container instance, no scaling

CCreate one ECS cluster, register container instances, use ECS Service with Auto Scaling

DCreate an ECS cluster and manually add containers without scaling

Step-by-Step Solution

Solution:

Step 1: Understand ECS cluster scaling
A single ECS cluster can run many container instances and apps together.
Step 2: Use ECS Service with Auto Scaling
ECS Service manages running tasks and can scale containers automatically based on demand.
Step 3: Combine cluster, instances, and auto scaling
Register container instances to the cluster and configure ECS Service Auto Scaling for automatic scaling.
Final Answer:
Create one ECS cluster, register container instances, use ECS Service with Auto Scaling -> Option C
Quick Check:
Cluster + instances + ECS Service Auto Scaling = scalable apps [OK]

Quick Trick: Use ECS Service Auto Scaling on one cluster for scaling apps [OK]

Common Mistakes:

Creating multiple clusters unnecessarily
Ignoring ECS Service Auto Scaling feature
Using Lambda instead of ECS for container apps
Manually scaling containers without automation
