Automated Continuous Integration (CI) and Continuous Deployment (CD) is a critical part of DevOps and is a skill that is in high demand. 

In this course, we will examine the subject in complete depth by walking through an example project and building a complex CI/CD pipeline on AWS. You will gain the following five extremely valuable and highly sought after skills:

  1. Learn to conceptualize and design CI/CD pipelines for your own web applications
  2. Deploy and scale web applications on Amazon’s Cloud infrastructure using AWS Elastic Beanstalk
  3. Build pipelines on Amazon’s Cloud infrastructure using AWS CodePipeline
  4. Learn advance topics such as Elastic Beanstalk Extensions and AWS Lambda to run custom actions in your CodePipeline
  5. Monitor your automated CI/CD pipelines

The tech landscape today is extremely competitive and is moving at an incredibly fast pace. With the emergence of cloud-based infrastructure, many startups are disrupting long-established businesses, industries and sectors almost on a daily basis as their entry barriers and costs keep on going down. DevOps and continuous integration / continuous deployment processes allows team to iterate often and innovate faster.

After taking this course, you will have a comprehensive understanding of continuous integration and continuous deployment processes. You will be able to confidently design a CI/CD pipeline for your own web applications. You will gain an in-depth understanding of AWS CodePipeline and AWS Elastic Beanstalk services. 

With these skills, you will be able to build fully automate deployments of your web applications on Amazon’s Cloud infrastructure.

The course is very hands-on and together we will walk through an example project. We will pick a web application and deploy it on Amazon’s Cloud using AWS Elastic Beanstalk. I will then demonstrate and create a fully automated CI/CD pipeline for our web application using AWS CodePipeline. I will cover both of these AWS services in complete depth while also giving you easy to follow step-by-step instructions. 

We will also cover some advance topics such as ebextensions and adding AWS Lambda functions in your AWS CodePipeline.

CI/CD for Web Applications

1
Section Overview

In this lecture, I will give a high level overview of what we are going to cover in this section. We will learn to conceptualize and design a CI/CD pipeline for web applications. 

2
Anatomy of a basic web application

Let's take a look at the anatomy of a basic web application (e.g. architecture and components involved). We need to understand the architecture of our web applications in order to design an effective CI/CD process. I have formulated a 4-step process to help you conceptualize and design a CI/CD pipeline -- we will cover 3 of those steps in this lecture.

3
Designing a continuous deployment pipeline for a web application

We will talk about the fourth step i.e. how to model a pipeline. We will walk through our example and design a basic CD pipeline using the four steps.

4
Managing Relational Database Changes and Deployments

In this lecture, we will talk about how you can manage relational database changes as part of your continuous deployment pipeline.

5
Deployments & Actions

We will talk about different types of actions that can be performed as part of your CI/CD pipeline (stand-alone vs. deployment actions).

6
Monitoring

Monitoring is important for automated CI/CD pipelines - what are the different types of approaches you can use to monitor your application as it progresses through your CD pipeline.

7
Common Challenges

What are some of the common challenges associated with fully automated CD pipelines? We will talk about two most common challenges associated with web applications that you will encounter.

Setup Project: Let's setup a basic PHP web application

1
Section Overview

In this section we will dive deeper into our example web application (built in  PHP). Our web application is called 'Fuzzy Telegram' and displays a random quote of the day.

2
Quick Cloud9 IDE Overview
3
Changes in Cloud9 IDE after AWS acquisition

Cloud9 IDE and Amazon Web Services: We use Cloud9 (C9) IDE in our course to quickly get to coding and workshops without going through the hassles of installing various applications such as PHP, Apache, etc. 

Cloud9 (C9) has recently been acquired by Amazon. They have changed the workflow and user interfaces a bit. In this text handout I will illustrate the major differences between the old Cloud9 IDE setup and the new AWS based one. 

4
Building Fuzzy Telegram PHP Web Application

Fuzzy Telegram web application talks to the Quotes API (https://theysaidso.com/api/) and fetches the random quote of the day. It stores it in a database so that any likes and # of views can be recorded against the quote. 

  • If you prefer another language: please feel free to replicate a similar web application in your preferred language of choice.
  • If you already have a web application: please feel free to skip to the next section however I will highly recommend you to atleast go through the 'Environment Variables' and 'Writing Database Migrations' lectures in this section as we will refer back to them when we are configuring our AWS CodePipeline and AWS Elastic Beanstalk environments
5
Using Environment Variables in Applications

Most modern web applications use environment variables as a way to store configuration options (e.g. database credentials). We will use environment variables in our web application. 

Another reason why we are keen to use environment variables is because Elastic Beanstalk supports this method so it is quite handy to rely on it for configuration options.

6
Configuring MySQL Database using Environment Variables

We will configure our database credentials using environment variables.

7
Writing Database Migration Scripts (Database Change Management Scripts for CD)

We will learn more about how / why to write database migration scripts. This enables us to automate database deployments in our CD pipelines. 

We will use PHINX (PHP Database Migration tool) in our example but the concept is broadly applicable to any Database change migration script  or tool that you choose going forward.

8
Unit tests using PHPUnit

We will quickly take a look at some example unit tests in our web application.

9
Checking in to code repository (Github)

Last step for us is to check everything into a code repository.

Deploy Project: Setting up AWS Elastic Beanstalk & RDS

1
Section Overview

In this lecture, I will give a high level overview of what we are going to cover in this section. We will will now dive deeper into AWS Elastic Beanstalk and deploy our web application on EB. We will also cover advance topics such as ebextensions and application versions.

2
Setting up Elastic Beanstalk - Part 1

Let's start configuring our AWS Elastic Beanstalk environment to deploy the web application. I will walk you through the advance configuration options available in Elastic Beanstalk.

3

Manual RDS / Database Deployment on Elastic Beanstalk

Manually running database migration scripts on our EC2 instance (in our example we will run phinx migration scripts).

7
Intro to Elastic Beanstalk Extensions (.ebextensions)

Introducing AWS Elastic Beanstalk Extensions (.ebextensions). A great way of customizing your EC2 / AWS environment. We will focus on how you can run custom scripts using ebextensions but their features are more broad (we won't cover all the features).

8
Workshop: Creating .ebextension to run Database migration scripts

Writing our first .ebextension script. The script will run our database migration script (phinx) as part of the deployment process to Elastic Beanstalk.

9
Creating a new environment for "Production"

Let's put everything together and create a new environment in our elastic beanstalk application. In this workshop we will create a new environment that will serve as the 'production' stage for our web application.

10
Application Versions

A quick overview of application versions in Elastic Beanstalk and why they are useful

Setting up a CI/CD pipeline using AWS CodePipeline

1
Section Overview

In this lecture, I will give a high level overview of what we are going to cover in this section. We will dive deeper into AWS CodePipeline. We will setup our first CD pipeline using AWS CodePipeline.

2
First, let's commit everything in Github

Let's just quickly check everything in to our code repository (github). We will use this code repository in our AWS codepipeline later.

3
Creating a new pipeline on AWS CodePipeline

Let's create our first AWS CodePipeline. I will walk you through some of the configuration options available when creating a new pipeline in AWS CodePipeline.

4
AWS CodePipeline in Action
5
Editing AWS CodePipeline and adding a new Stage

We will cover AWS CodePipeline concepts such as stages, actions and transitions.

6
Manually release a change in AWS CodePipeline

Let's take a look at how you can manually release changes in AWS CodePipeline.

7
Stage Transitions in AWS CodePipeline

We will talk about stage transitions in AWS CodePipeline and how you can disable/enable them.

Adding actions in AWS CodePipeline

1
Sequential and Parallel Actions

We will discuss different ways you can execute your actions in AWS CodePipeline.

2
Types of actions in AWS CodePipeline

We will talk about the actions offered by AWS CodePipeline.

3
Input & Output Artifacts

AWS CodePipeline has a notion of artifacts. In this lecture we will cover what those are and how to use them in your AWS CodePipeline.

4
Four methods to run custom builds/actions in AWS CodePipeline

In order for our CI/CD pipeline to be effective, we will most likely wish to run some custom script or custom logic. We will talk about the four different ways you can execute custom builds / custom scripts as part of your AWS CodePipeline.

Method # 1: Adding a custom deployment action to run unit tests

1
Part 1 - Setting up a new stage and environment for unit testing

1st method to run custom scripts in Pipeline is by executing deployment actions (e.g. ebextensions). In this lecture we will setup a new environment in Elastic Beanstalk that we will use to run our tests.

2
Part 2 - Adding script to run unit tests in Elastic Beanstalk

Continuing on from our previous lecture, we will write a new ebextension script to execute unit tests. We will configure this as part of our pipeline and see how our pipeline reacts to success/failures.

Method # 2: Invoking Lambda Functions in your AWS CodePipeline

1
Part 1 - Create S3 Bucket for your assets

2nd method to run custom scripts in Pipeline is by invoking AWS Lambda functions. 


We will talk about lambda functions and start our 3 part workshop to create a new lambda function that will upload our assets (CSS, JS and images) to S3.  We will then use the S3 bucket to serve static content for our web application.

Part 1 of 3: In this lecture, we will configure our S3 bucket to serve static content publicly.

2
Part 2 - Create Lambda Function to upload assets to S3

Part 2 of 3: In this lecture, we will setup our AWS Lambda function to upload static assets to an S3 bucket. We will also briefly talk about IAM permissions in AWS.

3
Part 3 - Adding Lambda Function in AWS CodePipeline

Part 3 of 3: In this lecture, we will take our newly created AWS Lambda function and configure it in our AWS CodePipeline.

Method # 3: 3rd party integrations in AWS CodePipeline

1
Workshop: Integrating GhostInspector for UI testing

The last two methods of running custom scripts in AWS CodePipeline is by integrating 3rd party services. We can do it either as Build or Test actions. In this lecture, I will just cover how to integrate a 3rd party 'Test' action but the same principle applies to the 'Build' action as well.

I will integrate GhostInspector (UI Testing Tool) in our AWS CodePipeline.

Real-life scenarios

1
Adding a manual approval step in AWS CodePipeline

In many practical situations, it is preferable to limit risks that automated CD pipelines pose to your business / customers. For example: their might be a critical launch event and you don't wish to be automatically deploying changes during the event as a precautionary step. Manual approval steps in CI/CD pipelines allow you to restrict transitions in pipeline.

2
Manually rolling back changes in AWS CodePipeline

Bugs and errors are a fact. We will talk about how you can quickly (albeit manually) rollback to a previous version of your application in AWS Elastic Beanstalk.

Monitoring your fully automated AWS CodePipeline

1
Section Overview

In this lecture, I will give a high level overview of what we are going to cover in this section. Monitoring is a key part of automated CI/CD pipelines. We will discuss different ways you can configure monitoring for your web applications when they are part of a fully automated CD process.

2
Workshop: Lambda Function to health check your web application

We will configure a lambda function to do a basic sanity HTTP test on our web application and configure it as part of our pipeline. 

3
Creating Alarms using CloudWatch

Quick overview of AWS CloudWatch and how you can use it to monitor your application / pipeline in AWS Elastic Beanstalk.
