🚀 Day 41: Setting up an Application Load Balancer with AWS EC2 🚀
Table of contents
Hi there! Hope you're still on your AWS journey with us. Yesterday, we delved into launch templates and EC2 instances. Today, we're about to tackle something equally exciting and important: Load Balancing! 🌐
What is Load Balancing? 🤔
Imagine you have a ton of work to do, but you've got some helpful friends. Load balancing is like having a super-organized friend who helps you distribute tasks among your buddies so that everyone stays busy and happy. 💼🙌
In AWS, Load Balancing helps us distribute incoming traffic across multiple EC2 instances, making our applications more reliable and faster. It's like having traffic police for the internet! 🚦
Elastic Load Balancing (ELB) 🌐
Amazon Web Services (AWS) offers Elastic Load Balancing (ELB), which is like the superhero of traffic management. ELB comes in three flavors:
Application Load Balancer (ALB) - This one operates at layer 7 and is perfect for complex routing and microservices. It's like the GPS of load balancers! 🗺️
Network Load Balancer (NLB) - Operating at layer 4, NLB is great for high-speed applications with low latency needs. It's the speedster of load balancers! 🏎️
Classic Load Balancer (CLB) - CLB operates at layer 4 too and is ideal for simpler load balancing tasks. It's like the good ol' reliable friend! 👥
🎯 Today's Tasks:
Task 1: Setting Up EC2 Instances with Apache Web Server
Launch 2 EC2 instances with Ubuntu AMI.
Use User Data to install the Apache Web Server.
Modify the index.html file to add your name to it.
Check your EC2 instances' public IP addresses and paste them in your web browser.
Voilà! You should see a webpage displaying info about your PHP installation.
Task 2: Creating an Application Load Balancer (ALB)
Create an Application Load Balancer in EC2 via AWS Management Console.
Add the EC2 instances you created earlier to the ALB as target groups.
Verify that the ALB is working smoothly by checking the health status of the instances and testing the load balancing magic. 🎩✨
That's it for today! Load balancing makes sure that your apps run smoothly even when they're super popular, just like a pro concert organizer. Keep up the great work! 👏👏
Stay tuned for more AWS adventures! ☁️🔜
