How to save money on AWS using EC2 Auto Scaling Groups Features?
What is an EC2 Auto Scaling Group?
An Amazon EC2 Auto Scaling group is a logical collection of several Amazon EC2 instances used for management and scaling purposes. AWS Auto Scaling groups let you use core features of the EC2 Auto Scaling service, including health checks, minimum/maximum instances, and scaling policies.
EC2 Auto Scaling functionality mainly centers around maintaining a specified amount of instances in a group or automatically increasing and decreasing the size of a group according to different aspects, such as application loads or predetermined schedules.
How to reduce AWS expenses using AWS EC2 Autoscaling groups?
AWS EC2 Auto Scaling Groups offer various functionalities to reduce expenses, including:
Scaling policies: You can establish policies to adjust the number of instances in your Auto Scaling Group based on the current demand. This way, you can prevent unnecessary expenses by increasing instances only during peak hours and reducing them during off-peak hours.
Instance types: AWS EC2 provides different types of instances with varying specifications and prices. You can select the most cost-effective instance type for your workload, thus saving money without compromising performance.
Spot instances: Bidding on spare EC2 capacity with Spot instances can save up to 90% on your EC2 costs. However, remember that they may not be suitable for all workloads as they can be terminated with little notice.
Scheduled scaling: You can schedule automatic adjustments to the number of instances in your AWS Auto Scaling Group, e.g., increase during business hours and decrease during weekends or holidays.
Load balancers: Load balancers distribute traffic across multiple instances, enhancing availability and scalability. By using them, you can also reduce costs by running only necessary instances for handling the current traffic load.
Additionally, here are some other cost-reduction strategies for EC2 Auto Scaling Groups:
Use instance reservations: Reserved instances provide significant discounts compared to on-demand instances. By purchasing reserved instances, you can save up to 75% on your EC2 costs. You can also combine instance reservations with Auto Scaling Groups for further savings.
Use smaller instance sizes: Smaller instance sizes usually cost less than larger ones. By choosing smaller instances, you can decrease EC2 costs without compromising performance. Auto Scaling Groups can also adjust the number of instances based on the current demand.
Optimize storage: EC2 offers different storage options, each with distinct performance and cost characteristics. By selecting the right storage option, you can save money without performance trade-offs. Auto Scaling Groups can also adjust storage capacity based on demand.
Use Amazon CloudWatch: CloudWatch provides real-time visibility into your EC2 resources, allowing you to optimize underutilized resources and save money. You can also use CloudWatch with AWS Auto Scaling Groups to monitor and adjust the number of instances based on demand.
Use instance lifecycle: The instance lifecycle automates the launching and terminating process of instances. By configuring AWS Auto Scaling Groups to launch Spot instances during high demand and terminate them during low demand, you can optimize costs.
Overall, AWS EC2 Auto Scaling Groups provide numerous features and strategies to reduce EC2 costs. Leveraging them can help you optimize infrastructure and achieve significant cost savings.
