If you're looking for a way to automatically scale your Amazon Elastic Compute Cloud (EC2) instances according to the demand, Amazon EC2 Auto Scaling is the perfect solution for you. With this AWS service, you can effortlessly manage your application's availability and ensure that it runs smoothly, even during unexpected traffic spikes.
Amazon EC2 Auto Scaling works by automatically adjusting the number of instances running in your application based on the demand. This process is performed using pre-defined rules, which you set to adjust the number of instances based on various metrics, including CPU utilization, network traffic, and database connections.
When creating an EC2 Auto Scaling group, you define the maximum and minimum number of instances that you want to be running at any given time. If the application demand exceeds the current capacity, the service will automatically spin up new instances until the maximum number is reached. On the other hand, if the demand decreases, or if there are instances that are underutilized, the service will automatically terminate those instances to save on costs.
Amazon EC2 Auto Scaling has several benefits, including:
