Missing Implementations

We currently lack the following features:

• Deploy to DigitalOcean with Vagrant.
• Completing our front-end design.
• Refactor the tests to work with new design.
• Implement UI and end-to-end tests.
• Make UML-diagram of system.
• Add logging.
• Check security.

It would be nice to have the following features:

• Create automatic releases when merging into main branch.

Weeks

Week 1

Refactor ITU-MiniTwit to work on modern system.

• 1) Adding Version Control.
• 2) Try to develop a high-level understanding of ITU-MiniTwit.
• 3) Migrate ITU-MiniTwit to run on a modern computer running Linux.
• 4) Share your Work on GitHub.

Week 2

Refactor ITU-MiniTwit in another programming language and tech stack.

• 1) Refactor ITU-MiniTwit to another language and technology of your choice.
• 2) Containerize ITU-MiniTwit with Docker.
• 3) Describe Distributed Workflow.

Week 3

Continue refactoring, introduction of DB abstraction layer, and deployment of your ITU-MiniTwit to a remote server.

• 1) Implement an API for the simulator in your ITU-MiniTwit.
• 2) Continue refactoring of your ITU-MiniTwit.

Week 4

Continue refactoring, Setup CI & CD for reproducible builds, tests, delivery, and deployment.

• 1) Complete implementing an API for the simulator in your ITU-MiniTwit.
• 2) Creating a CI/CD setup for your ITU-MiniTwit.
• 3) Continue refactoring of your ITU-MiniTwit.

Week 5

Cleaning and polishing of your ITU-MiniTwit, introduction of DB abstraction layer, and entering maintenance (Simulator starts).

• Complete and polish your ITU-MiniTwit implementation
  • Add missing features.
  • Introduce a DB abstraction layer in your ITU-MiniTwit.

Week 6

Add monitoring to your ITU-MiniTwit and peer-review.

• Add Monitoring to Your Systems.
• Software Maintenance II: Check the user interface of another group (Group m, Jason Derulo)
  • Do you see a public timeline?
  • Does the public timeline show messages that the application received from the simulator?
  • Can you create a new user?
  • Can you login as a new user?
  • Can you write a message?
  • After publishing a message, does it appear on your private timeline?
  • Can you follow another user?

Week 7

Enhancing CI/CD setup with test suite and static code analysis.

• 1) Add tests to your CI chain (Selenium)
• 2) Enhance your CI Pipelines with at least three static analysis tools
  • eslint (typescript)
  • codeql (csharp)
  • Snyk (containers)
• 3) Add Maintainability and Technical Debt estimation tools to your projects
  • Sonarqube
  • Code Climate (hosted from Code Climate, not in GitHub actions)
• 4) Software Maintenance

Week 8

Add logging to your ITU-MiniTwit.

• 1) Add Logging to Your Systems
• 2) Test that Your Logging Works
  • The Devs introduce a bug; the Ops resolve the bug by using the logs.

Week 9

Security Assessment & Pen Testing.

• 1) Perform a Security Assessment

Course description

As a participant of the DevOps course at the IT University of Copenhagen, we are in for a hands-on learning experience. Every week, we will make changes to a Twitter project to put into practice the concepts and tools that we learn in class. Here is what we will be covering during this course:

• Bash: We will learn the basics of the shell, navigate the file system, and execute commands.

• Packaging applications: We will get hands-on experience with packaging applications for distribution and deployment.

• Containerization: We will learn how to create and manage containers to isolate applications and their dependencies.

• Virtual Machines: We will explore the use of virtual machines for testing, development, and deployment.

• CI/CD: We will understand the concepts of Continuous Integration and Continuous Deployment, and implement them using popular tools such as Jenkins and GitLab.

• Monitoring: We will learn how to monitor the performance of our applications and infrastructure to ensure optimal operation.

• Maintainability: We will gain insight into making our applications maintainable, and understand the importance of clean code and testing.

• Log analysis: We will collect and analyze log data to identify and resolve issues in our applications.

• Web security: We will explore the importance of web security and the measures we can take to protect our applications and users.

• Scalability: We will understand the concept of scalability and learn how to design and implement scalable applications.

• Load balancing: We will balance loads across multiple servers to improve performance and reliability.

• Infrastructure as Code: We will manage and provision infrastructure using code, and understand how this can improve the consistency and reliability of our deployments.

By the end of this course, we will have developed a solid foundation in DevOps concepts and practices, and will have the skills and confidence to build, deploy, and manage applications at scale.
