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. ❤️ 𝐅𝐨𝐥𝐥𝐨𝐰 @prodevopsguy 𝐟𝐨𝐫 𝐦𝐨𝐫𝐞 𝐬𝐮𝐜𝐡 𝐜𝐨𝐧𝐭𝐞𝐧𝐭 𝐚𝐫𝐨𝐮𝐧𝐝 𝐜𝐥𝐨𝐮𝐝 & 𝐃𝐞𝐯𝐎𝐩𝐬!!! // 𝐉𝐨𝐢𝐧 𝐟𝐨𝐫 𝐃𝐞𝐯𝐎𝐩𝐬 𝐃𝐎𝐂𝐬: @devopsdocs

📢 DevOps Project-22: ☁️ AWS Fully Serverless Architecture with CI/CD ♾ 🔗 Project Link: HERE 🔄 Project Overview :- In this article, we’ll explore a practical example of a Fully Serverless Architecture implemented using Terraform — a popular IaC tool and CI/CD implemented using GitHub Actions. The code repository we’ll be examining is hosted on GitHub I have a NodeJS Cloud Native API which I have used to deploy in this architecture. This API is specifically designed to make use of AWS serverless services. Following are the serverless services used in this project: ➡️API Gateway ➡️Lambda ➡️Aurora Serverless (MySQL) ➡️AWS Simple Storage Service (S3) ➡️AWS Secrets Manager ➡️AWS Certificate Manager (ACM) ➡️Cloudwatch Logs and Metrics ➡️Route53
