AWS Compute Services: EC2, Elastic Beanstalk, Lambda and ECS

EC2 (Elastic Compute Cloud), Elastic Beanstalk, Lambda and ECS (Elastic Container Service) are the compute service offerings from AWS. Below are some basic points regarding these AWS compute services:

EC2

1. Most common AWS service called Elastic Compute Cloud.

2. This is the Virtual Server in AWS.

3. Categories of EC2:
  • On Demand Instances (Charged hourly)
  • Spot Instances (Bid-based, Choose it when Start and End date is not a concern)
  • Reserved Instances (1 year or 3 year contract, cheaper than on-demand)
  • Scheduled Reserved Instances (Scheduled Instances)
  • Dedicated Host and Instances
4. EC2 Types:
  • General Purpose (T2, M5)
  • Compute Optimized (C5)
  • Memory Optimized (X1, R4)
  • Storage Optimized (I3, D2)
  • Accelerated Computing / GPU Optimized (P3, G3, F1)
Please note that EC2 is the most important topic in AWS. So, for details, please go through the official documentation.

Elastic Beanstalk

1. Simple way to deploy your application on AWS. No need to take headache of managing the infrastructure.

2. Just upload your application code and the service automatically handles all the details such as resource provisioning, load balancing, auto-scaling, and monitoring.

3. Supports PHP, Java, Python, Ruby, Node.js, .NET, Go and Docker.

4. Elastic Beanstalk uses core AWS services such as Amazon EC2, Amazon Elastic Container Service (Amazon ECS), Auto Scaling, and Elastic Load Balancing to support your applications.

5. Monitor and manage the health of your applications.

Lambda

1. Lambda lets you run code without managing any server (Go Serverless). Just upload your code to Lambda or write your code in Lambda Code Editor and it takes care of everything required to run it.

2. Any code uploaded to Lambda becomes Lambda Function. Code should be written in stateless style. If you need to store any state in between, save it to S3, Dynamo DB etc. and then retrieve from there.

3. Lambda can be directly triggered by AWS services such as S3, DynamoDB, Kinesis, SNS, CloudWatch, API Gateway and Web Applications. Use cases: https://aws.amazon.com/lambda/

4. Languages supported: C#, Java, Python, Ruby, Go, Powershell, Node.js

5. You pay only for the compute time you consume - there is no charge when your code is not running. You are charged for every 100ms your code executes and the number of times your code is triggered. You don't pay anything when your code isn't running.

ECS

1. Elastic Container Service (ECS) is a container orchestration service that supports Docker containers and allows you to easily run and scale containerized applications on AWS. 

2. Amazon ECS eliminates the need for you to install and operate your own container orchestration software, manage and scale a cluster of virtual machines, or schedule containers on those virtual machines.

3. Containers without Servers: With Fargate, you no longer have to select Amazon EC2 instance types to run your containers.

4. Amazon ECS launches your containers in your own Amazon VPC, allowing you to use your VPC security groups and network ACLs. 

5. With simple API calls, you can launch and stop Docker-enabled applications, query the complete state of your application, and access many familiar features such as IAM roles, security groups, load balancers, Amazon CloudWatch Events, AWS CloudFormation templates, and AWS CloudTrail logs.
