In today’s information technology landscape, effective resource management and service stability are essential requirements for businesses. As the number of users increases, ensuring consistent system performance becomes a significant challenge. Therefore, the topic “Implementing Workload Management System with AWS” will focus on building a flexible and efficient resource management system by leveraging powerful AWS tools and services, such as Auto Scaling, Load Balancer, and CloudWatch.
What is Auto Scaling Group, and Why Use Auto Scaling Group?
Auto Scaling Group (ASG) is an Amazon Web Services (AWS) service that automatically adjusts the number of servers (instances) based on the actual demand of the application. When traffic or usage demand increases, ASG can automatically create additional servers to maintain stable performance. Conversely, when demand decreases, ASG reduces the number of servers to save costs.
Key Benefits of Auto Scaling Group:
Automatic Scalability: Increases or decreases the number of servers based on set conditions, such as CPU usage, memory, or the number of requests.
Cost Optimization: Automatically shuts down unnecessary servers when demand decreases, helping save resources.
Ensures Availability: Maintains a minimum number of servers to ensure the system remains operational, even if some servers experience issues.
Elastic Load Balancer (ELB) is an Amazon Web Services (AWS) service used to automatically distribute incoming traffic across multiple servers (instances) in one or more Availability Zones. ELB ensures that requests are evenly distributed, preventing overload on any single server, thereby optimizing performance and increasing the application’s availability.
Launch Template is a tool in Amazon Web Services (AWS) that simplifies and automates the creation of virtual servers (EC2 instances) by storing initialization configurations. By using Launch Template, you don’t need to manually configure each time a new instance is created, saving time and ensuring consistency.
Target Group is a component of the Elastic Load Balancer (ELB) used to define and manage the EC2 instances that the Load Balancer will distribute traffic to.
