Know before you go​

The following information will provide general guidance and safety-tips before running through the workshop.

Target Audience​

Developers, Architects, DevOps, SysOps, Testers. Anyone working with Java applications who is interested in using containers.

Experience Required​

Level: 200-300 (Intermediate to Advanced).

In this workshop you will be editing and changing Java source code. It would be helpful to be familiar with the Java programming language. If you are not, that's ok, please follow the instructions carefully.

You will also need a basic understanding of the AWS console and CLI.

Cost​

If you run this workshop in your own AWS Account (without being provided an account at a hosted event) the resources that are created during this workshop will incur cost and will be billed to your account. Please make sure you delete all resources after the workshop to avoid unnecessary costs in the cleanup section.

The workshop uses an Amazon RDS PostgreSQL database, it's cost in the eu-west-1 region is: 1 instance(s) x 0.078 USD hourly x (100 / 100 Utilized/Month) x 730 hours in a month = 56.9400 USD Amazon RDS PostgreSQL instances cost (monthly): 56.94 USD

If you choose to use AWS Cloud9 as a development environment it will be charged at the EC2 instance price.

Depending on the deployment options that you chose you will be charged based on the Amazon EKS pricing.

Supported regions​

If you run the workshop on your own, you can choose any AWS region. However, if you want to use AWS Cloud9 as a development environment, you should check the AWS Regional services list to see if it's available in the desired region.

At an AWS-managed event you can just follow the instructions of your facilitator who will preselect a region for you.

Clean Up​

  1. Execute the following commands to clean up your workshop environment:
# approximately 60 minutes
~/environment/java-on-aws/labs/unicorn-store/infrastructure/scripts/99-destroy-all.sh
info

The deletion of the stacks might take more than 60 minutes.

warning

If you created resources manually "Using UI (AWS Console)" you need to delete these resources manually

Delete Cloud9 instance CloudFormation → Stacks → java-on-aws-workshop → Delete
