Remember that time when everyone was like, "Coding? Nah, DevOps is all about automation, CI/CD, blah-blah." Yeah, me too. In 2020, freshman year, convinced myself I could skip "DSA", "messy code" & just focus on DevOps tools. Big mistake. If you are from a Tier 3 college & genuinely want to do good, learn & earn some good bucks, coding & basic computer science knowledge are good to have.
In 2020, there wasn't much content on DevOps (or could be my algo), but there were few solid senior OPS / DevOps folks whom I followed. In recent times, there has been huge content overload, conflicting advice, and enough acronyms to fill a dictionary. If I were to start in 2023, I would've been lost too.
Why I am sharing this? During my freshman year, I used to follow a guy, from whom I got to know about DevOps. He used to say, "Giving back to the community." In my freshman year, I didn't understand what he meant, but now that I do, I want to share this list of free but best resources/bootcamps you can find online.

Each technique enables organizations to optimize Kubernetes usage and minimize expenses
𝟭. 𝗥𝗶𝗴𝗵𝘁-𝘀𝗶𝘇𝗶𝗻𝗴 𝗿𝗲𝘀𝗼𝘂𝗿𝗰𝗲𝘀:
Analyze app resource usage, adjust CPU/memory as needed. Avoid over-provisioning to save costs
𝟮. 𝗘𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁 𝗡𝗼𝗱 & 𝗣𝗼𝗱 𝗔𝘂𝘁𝗼 𝗦𝗰𝗮𝗹𝗶𝗻𝗴:
Enable cluster auto-scaling and use Horizontal Pod Autoscaler (HPA) and Vertical Pod Autoscaler (VPA) to add or remove nodes / pods based on resource utilization, reducing idle costs
𝟯. 𝗣𝗼𝗱 𝗗𝗶𝘀𝗿𝘂𝗽𝘁𝗶𝗼𝗻 𝗕𝘂𝗱𝗴𝗲𝘁 (𝗣𝗗𝗕):
Set up PDBs to control how many pods of a specific deployment or replica set can be down simultaneously during disruptions, ensuring high availability without overprovisioning
𝟰. 𝗡𝗼𝗱𝗲 𝗧𝗮𝗶𝗻𝘁𝗶𝗻𝗴 𝗮𝗻𝗱 𝗧𝗼𝗹𝗲𝗿𝗮𝘁𝗶𝗼𝗻:
Taint nodes for workload-specific delays, prioritize critical tasks on untainted nodes, and use cheaper tainted nodes for less critical tasks
𝟱. 𝗖𝗼𝗻𝘁𝗮𝗶𝗻𝗲𝗿 𝗥𝗲𝗴𝗶𝘀𝘁𝗿𝘆 & 𝗜𝗺𝗮𝗴𝗲 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻:
Use cost-efficient container registry, follow image best practices (e.g., multi-stage builds) for smaller images and reduced pull times & storage costs
𝟲. 𝗦𝗽𝗼𝘁 𝗶𝗻𝘀𝘁𝗮𝗻𝗰𝗲𝘀:
Utilize spot instances for non-critical tasks; they're cheaper but can be terminated quickly. Ideal for stateless, fault-tolerant apps

Efficient GitHub branching strategies can be a game-changer for your CI/CD pipeline and overall workflow. Let's explore some key strategies that can streamline your development process:
1. Main Branch (main/master): The production-ready branch. All code here should be stable and tested.
2. Feature Branches: Branch off from the main branch to work on new features. Keep them short-lived and merge back to main once complete and reviewed.
3. Release Branches: Create these when you're preparing a new release. They allow for final bug fixes and polishing before merging into the main branch.
4. Hotfix Branches: For urgent fixes on the production code. These branches are crucial for quick and isolated bug fixes.
5. Development Branch (develop): An optional branch that serves as an integration branch for features. This is where ongoing development happens before merging into the main branch.
6. Epic Branches: For larger projects, an epic branch can group related feature branches. It helps in managing complex development work.

Basic 📱 Git Flow in DevOps ♾ CI-CD!
1️⃣ . Developer Creates Feature Branch: The developer creates a new feature branch and is used to work on a new feature or a specific task.
2️⃣ . Developer Writes Code: The developer writes the necessary code for the feature in their local development environment.
3️⃣ . Developer Commits Changes: Once the developer is satisfied with the changes, they commit the changes to the feature branch in the local Git repository.
4️⃣ . Developer Creates Pull Request: The developer pushes the committed changes by creating a pull request to merge the feature branch into the main branch.
5️⃣ . Code Review by Team: The pull request initiates a code review process where team members review the changes.
6️⃣ . Approval of Pull Request: After addressing any feedback and making necessary adjustments, the pull request is approved by the reviewers.
7️⃣ . Merge to Main Branch: The approved pull request is merged into the main branch of the Git repository.
8️⃣ . Triggers CI/CD Pipeline: This automation ensures that the changes are continuously integrated and deployed.
9️⃣ . Then we follow the procedure for building and testing the code, deploying to staging env. Once the tests in the staging environment pass, a manual approval is required to deploy the changes to the production environment. Once the code is deployed to production env, the prod env is monitored using Prometheus to track the performance and health of the application. The collected metrics are visualized using Grafana. Finally alerts are configured.
