AWS Auto Scaling
Understand how Auto Scaling works in AWS, its benefits, and where it is useful.
While governing an infrastructure on the cloud, the resources deployed must be capable of handling the load. AWS Auto Scaling is a service that automatically adjusts the number of compute resources, such as EC2 instances, to match the current demand for applications. This dynamic resource management ensures that applications have the right capacity to handle traffic efficiently without over-provisioning or under-provisioning resources.
AWS Auto Scaling comprises of Amazon EC2 Auto Scaling and Application Auto Scaling services. The Auto Scaling service works by monitoring applications and automatically scaling in (decreasing capacity) or scaling out (increasing capacity) based on predefined policies, real-time metrics, and schedules. This makes it an essential component of cloud resource management, particularly in environments with variable workloads.
How Auto Scaling works
AWS Auto Scaling operates by continuously monitoring key metrics such as CPU utilization, memory usage, and request count. These metrics can be tracked using Amazon CloudWatch, which provides the data needed to make scaling decisions. Here are some key concepts ...
