Welcome to Day 41 of the #90DaysDevOpsChallenge, where we delve into the intricate world of Load Balancing in Amazon EC2, placing a special emphasis on Elastic Load Balancing (ELB) and the Application Load Balancer (ALB).
Understanding Load Balancing
Load Balancing stands as a cornerstone in large-scale computing systems, ensuring optimal resource utilization by distributing workloads across multiple servers. This not only enhances the reliability but also significantly boosts the performance of applications.
Elastic Load Balancing (ELB)
Elastic Load Balancing, an AWS service, automates the distribution of incoming traffic across multiple EC2 instances. In today's exploration, our focal point is the Application Load Balancer (ALB), operating at layer 7 of the OSI model. It's specifically designed for applications with advanced routing and microservices requirements.
Tasks for Mastery
Task 1: Exploring EC2 Instances
Launch EC2 Instances: Begin by deploying 2 EC2 instances, utilizing the Ubuntu AMI. Leverage User Data to install the Nginx web server, a widely used and versatile choice.
Personalize Content: Enhance your understanding by modifying the index.html file on each instance, featuring personalized content. This step not only demonstrates the dynamic capabilities of web servers but also showcases the potential for customizing user experiences.
Access Personalized Content: With the personalized content in place, take a step further and display it by accessing the public IP addresses of the instances. This hands-on practice solidifies your understanding of content delivery through EC2 instances.
Task 2: Mastering Application Load Balancer
Create ALB: Transition to the intricacies of Load Balancing with ALB. Establish an Application Load Balancer in EC2 through the AWS Management Console, gaining insights into the configuration options and considerations.
Configure Instances: Dive into the nuances of ALB by adding the EC2 instances configured in Task 1 to the ALB as target groups. Understand how ALB intelligently distributes incoming traffic, optimizing resource utilization and enhancing application performance.
Validation: Put your newly acquired knowledge to the test. Verify ALB functionality by checking the health status of target instances and conducting tests to evaluate the load balancing capabilities. This step ensures a practical understanding of how ALB contributes to a robust and scalable architecture.
