GO on AWS - Coding, Serverless and Infrastructure as Code

How to download and install GO in different environments.

GO is

- Fast

- Mature

- Quality through rigidity , e.g. static typing(*)

- Less maintenance costs

In this first exercise you will learn about the three levels of exercise:
1) Challenge: Just use the description and try it own your own
2) Free: Use step by step example without code
3) Guided: Watch the video

Starting with simple variables.

Your first program. We start with just a few variable declarations.

Variable scopes are vital to understanding that sometimes different variables may have the same name!

Variable scopes are vital to understanding that sometimes different variables may have the same name! To fully understand scopes, we do an exercise.

Do you think pointers are complicated? They are no. Let me give you a simple explanation.

This first datatype is available in almost any programming language. The only difference is the fixed length. Let's explore this.

Slices are the better arrays. Have a look at the most crucial type in GO.

Maps, dictionary - the name is different across the programming languages. Maps are your small database, so check it out.

Structured are composed of datatypes.

Structures start easy and become more complex to be the solution to complex problems.

You will use structures often used in AWS. So it is worth some training.

This lecture is about how GO implements the features of dynamic languages. Prepare for enhanced duck-typing.

Modules are the base of the GO dependency system since GO 1.13.

Modules are the base of the GO dependency system since GO 1.13. You will use them in almost every program. So it is worth an exercise.

Functions are just functions. This lecture is about how to define and call them. Again GO has its ways of solving problems.

Train functions executing through different parts of the program.

GO is object-oriented. It just concentrates on vital features.

This lecture shows you how to deal with the AWS event JSON files.

A late introduction to interfaces.

The most famous control statement.

Combine multiple ifs with switch.

The only loop you need.

Access all AWS services with the GO SDK.

This lecture combines GO knowledge and basic SDK knowledge.

Access the EC2 service - a starter for AWS API usage.

How to write files, aka objects to S3.

This lecture is a short introduction to the CloudFormation service API.  Code a stack counter!

This exercise goes one step further: List all resources inside a stack.

This lecture shows a safe way to distribute files.  You implemented it as a command line app.

You implemented it as a command line app.

This lecture is a short introduction to the S3 storage service.

With S3, you can save a large number of files. This lecture shows you how to handle this in a fast way. Also, this is the introduction to concurrency in GO with goroutines.

With S3, you can save large files up to 5TB. Put the standards API calls are only working up to 5 GB. Meet multi-part-upload.

This lecture shows the different ways to trigger events: Direct, SNS and event bridge.

The lecture is an introduction the NoSQL storage service DynamoDB.

The lecture explains the basic DynamoDB terms.

Simplify data access with structures. Migrate json events to structs.

The standard DynamoDB way to query data is quite complicated. The expression package helps!

This lecture teaches how to use an IAM role. Roles enable cross-account access.

This lecture discusses Infrastructure as Code (IaC) - written in GO.

This lecture shows you how to create your first AWS-CDK (Cloud Development Kit) program.

Here I show you some features which helped me - a lot!

Let me show you the actions from zero to hero with IaC with CDK.

Much simpler as in the SDK section: Create a DynamoDB Table with the CDK,

It's good to know the different deployment options. Are dependencies files too large? Use container deployment. Is deployment too slow? Use fast direct deployment. Let me show you how!

DSL: DynamodDB, S3 and Lambda - this is one standard serverless architecture!

Create the standard serverless architecture!

Automated testing enhanced program quality. This lecture introduces the integrated testing pyramid. We look at Unit and integration testing for program and infrastructure code both.

Basics of writing GO unit tests. Batteries included!

AWS stores events as JSON. What is the structure of an event? How to deal with these events?

This lecture is a short introduction to interface-based API unit testing.

This lecture shows the more flexible, straightforward solution to test AWS API calls that keep your program code untouched. AWS mocks with reflection!

This lecture explains how to test the generated CloudFormation of a CDK app.

Now we define integration testing with CDK/IaC: Test the deployed infrastructure.

I will show you the definition and practical execution of all parts of the integrated test pyramid.

I use task a lot - it will be helpful to you also.

Congratulation - Good job!

You finished the course and learned a lot.
