AWS Free Tier

AWS allows to explore more than 100 products and start building on AWS using the Free Tier. You can check the details here. Using AWS Free Tier, we will use:

  • Amazon EC2 - 750 hours per month of Linux t2.micro

  • Amazon RDS - 750 hours per month of PostgreSQL db.t2.micro database usage and 20 GB of General Purpose (SSD) database storage

  • Amazon Elastic Block Storage - 30GB any combination of General Purpose (SSD) or Magnetic, 1 GB of snapshot storage

Services not covered by the Free Tier

Charges that you may incur because of these workshops should not exceed 1$. You may be charged because of the following services we will use:

  • Application Load Balancer

  • CloudWatch

  • VPC Endpoint

  • Secrets Manager

  • EBS (snapshots)

We will destroy all resources at the end of the workshops.

The infrastructure we will build

consists of:

  • Virtual Private Cloud with:

    • 4 subnets (2 public and 2 private)

    • Internet Gateway

    • 2 Route Tables

    • VPC Endpoint

  • Application Load Balancer

  • Auto Scaling Group

  • Relational Database Service

  • Security Groups

  • IAM Role

We will use the AWS Secrets Manager service to store credentials for the database. Also, we will build our own Amazon Machine Image that contains Node.js application code. The image will be used by Auto Scaling Group to spin up EC2 instances.
