Node groups (managed, self-managed, Fargate) in AWS - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a managed node group in AWS EKS?

A managed node group is a set of worker nodes in EKS that AWS automatically manages for you. AWS handles tasks like provisioning, updating, and scaling the nodes.

beginner

How does a self-managed node group differ from a managed node group?

A self-managed node group is where you manually create and manage the worker nodes yourself. You handle updates, scaling, and maintenance instead of AWS.

beginner

What is AWS Fargate in the context of EKS?

AWS Fargate lets you run containers without managing servers or nodes. It automatically provisions and scales compute resources for your pods.

beginner

Which node group type requires you to manage the underlying EC2 instances?

Self-managed node groups require you to manage the EC2 instances, including updates, scaling, and health checks.

beginner

What is a key benefit of using Fargate over managed or self-managed node groups?

Fargate removes the need to manage servers or clusters, letting you focus only on your containers and applications.

Which node group type automatically handles node updates in EKS?

A Managed node group

B Self-managed node group

C Fargate

D On-premises nodes

Managed node groups are automatically updated by AWS, unlike self-managed nodes.

Which option lets you run containers without managing EC2 instances?

A Self-managed node group

B Managed node group

C Fargate

D Auto Scaling group

Fargate runs containers serverlessly without EC2 instance management.

Who is responsible for scaling in a self-managed node group?

A You manage scaling manually

B Scaling is not possible

C Fargate scales automatically

D AWS automatically scales

In self-managed node groups, you handle scaling yourself.

Which node group type is best if you want full control over EC2 instances?

A Managed node group

B Lambda

C Fargate

D Self-managed node group

Self-managed node groups give you full control over EC2 instances.

What is a main advantage of managed node groups over self-managed?

A You must manage updates manually

B AWS handles node lifecycle management

C You cannot scale nodes

D They do not support Kubernetes

Managed node groups let AWS handle provisioning, updates, and scaling.

Explain the differences between managed node groups, self-managed node groups, and Fargate in AWS EKS.

Think about who manages the servers and how scaling and updates happen.

Describe a scenario where using Fargate would be better than using managed or self-managed node groups.

Consider ease of use and operational overhead.
