📝 Day 10 of My AWS + DevOps Journey ☁️
🚀 Aspiring Cloud & DevOps Engineer | AWS Free Tier User | Learning by Building
Hi, I’m Sukaran Mahajan — I am working as System Administrator and currently on a focused journey to become job-ready in AWS Cloud, DevOps, and Infrastructure automation. With a growing foundation in Linux, Git, Docker, and Terraform, I’m documenting everything I learn to help others and strengthen my understanding.
💡 Currently Learning: • AWS (EC2, S3, IAM, VPC, Lambda) • Docker, Terraform & Ansible • CI/CD tools (GitHub Actions, Jenkins) • Kubernetes basics
🛠 Hands-on Projects: • Flask + Docker App Deployment • Terraform-based AWS Infrastructure • EC2 SSH automation & S3 access control
📝 I also write beginner-friendly technical blogs on Hashnode: 🔗 https://devopswithsukaran.hashnode.dev
💼 Open to internships, DevOps/cloud roles, and collaborative projects.
Let’s connect and grow in tech together! 🔗
🚀 Topic: What is a Load Balancer in AWS and Why It Matters?
---
In today’s learning, I explored the concept of Load Balancing in AWS — a critical part of designing highly available and scalable applications.
🔄 A Load Balancer automatically distributes incoming traffic across multiple EC2 instances. It's like a traffic cop that makes sure no server is overwhelmed, improving both performance and fault tolerance.
---
💡 Real-World Use Case:
Imagine you're running an e-commerce site. During a sale, thousands of users visit your site at once. Instead of relying on one server, you launch multiple EC2s and set up an Application Load Balancer. It ensures:
Users are automatically routed to healthy servers
No single instance bears all the load
Zero downtime during peak traffic
---
🔧 What I Practiced Today:
Created an Application Load Balancer
Registered multiple EC2 instances
Verified automatic traffic distribution
Tested health check failures and auto-removal of failed instances
---
📚 Key Takeaways:
Load Balancers ensure availability, scalability, and fault tolerance
ALB works best for web apps (HTTP/HTTPS)
You can combine Load Balancer with Auto Scaling for full resilience
---
🔥 Every day, I realize that building reliable infrastructure is more about smart design than just writing code.
