🚀 DevOps Journey: Day 22-23 – Microservices Deployment Planning & LeetCode

🔹 Current Focus: Deploying My Node.js Backend as Microservices for Free

In the past two days, I’ve been planning how to deploy my Node.js backend (with Redis and MongoDB) using a microservices architecture while ensuring zero cost by leveraging free-tier cloud services.

🔍 Key Considerations

• Containerization: Dockerizing services for portability and scalability.

• Orchestration: Exploring Kubernetes for managing microservices.

• Infrastructure as Code (IaC): Considering Terraform for automated deployment.

• Hosting Services: Finding a completely free cloud provider for:

  • Running Node.js microservices

  • Hosting Redis and MongoDB

  • Managing networking, scaling, and security

• CI/CD Pipeline: Evaluating Jenkins/GitHub Actions for automating deployments.

🔥 LeetCode Practice – Binary Trees

Alongside DevOps, I tackled some binary tree problems:
✅ Kth Smallest Element in a BST (Medium)
✅ Construct Binary Tree from Preorder & Inorder Traversal (Medium)
✅ Binary Tree Maximum Path Sum (Hard)
✅ Serialize and Deserialize Binary Tree (Hard)

🚀 Next Steps

✅ Finalizing the architecture for the deployment.
✅ Researching the best free-tier cloud options.
✅ Setting up Docker, Kubernetes, and Terraform for infrastructure setup.

Stay tuned for updates as I tackle this challenge! 🚀💡
