AWS Management and Governance Services: A Comprehensive Guide
AWS Auto Scaling is a service that automatically adjusts the number of compute resources in your application based on demand. It monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. AWS Auto Scaling ensures that you have the right amount of resources at any given time, scaling up when demand increases and scaling down during less busy periods.
Components of AWS Auto Scaling:
- Dynamic Scaling: Automatically adjusts resources based on demand using: Target Tracking Scaling: Maintains a target metric (e.g., CPU utilization). Step Scaling: Makes adjustments based on specified thresholds.
- Scheduled Scaling: Sets scaling actions at predefined times based on predictable traffic patterns.
- Predictive Scaling: Uses machine learning to forecast demand and adjust resources in advance.
- Manual Scaling: Allows manual adjustment of resource capacity.
- Instance Refresh: Replaces instances to update applications or apply patches.
Real-life Use and Example:
- Example: An e-commerce website experiences fluctuating traffic, with peaks during sales events. Using AWS Auto Scaling, the website automatically scales its fleet of EC2 instances up during high traffic periods to maintain performance and scales down during off-peak hours to save costs.
- Use Case: Organizations use AWS Auto Scaling to ensure their applications have the right amount of compute resources at all times, reducing costs and improving reliability, especially for applications with variable workloads such as web applications, data processing tasks, and microservices architectures.
AWS CloudFormation is a service that provides a common language for describing and provisioning all the infrastructure resources in your cloud environment.
