AWS Auto Scaling is a feature that tracks your applications and automatically adjusts capacity to maintain its performance at the cheapest price. Using AWS Auto Scaling, it’s easy to set up application scaling for multiple resources across multiple services in just a matter of minutes.
If you’re already using Amazon EC2 Auto Scaling to dynamically scale your Amazon EC2 instances, you can now combine it with AWS Auto Scaling to scale additional resources for other AWS services. With AWS Auto Scaling, your applications always have the exact resources at the right time.
Being a beginner, you should get started with AWS Auto Scaling using the AWS Management Console, Command Line Interface- CLI, or SDK. AWS Auto Scaling is available at no additional charge. You pay only for the AWS resources needed to run your applications.
Why use AWS Auto-scaling?
AWS Auto Scaling can help you boost your consumption and cost efficiencies when consuming AWS services, so you only pay for the resources you actually need. When the pressure decreases, AWS Auto Scaling will automatically remove any excess resource capacity, so you avoid overspending.
Let’s have an example:
Suppose you have made an e-commerce website and usually your website hits approximately 500 users per day, but now you have to start an end of year’s sale and you started getting 500+ users and due to excess load on your servers (the criteria you set for the number of users that can visit your web), your web isn’t responding timely and you’re losing the customers now you are required to purchase extra servers and make additional space in your room to adjust them there (doesn’t it sounds too much time-consuming and hectic work?).
Here comes the AWS Auto-scaling feature that provides you with the number of servers you need by only paying for what you use only no matter how many servers you have.
Another benefit of AWS Auto-scaling is that it automatically increases or decreases its usage of servers and some other services.
See, how beneficial it is to use the AWS Auto-scaling feature for your business as it helps you reduce the budget and prevents the additional space of your room.
Difference between AWS Auto-scaling and EC2 AWS Auto-scaling
AWS Auto-scaling
AWS Auto-Scaling is a feature that monitors your applications and automatically adjusts capacity to maintain its performance at the cheapest price. Using AWS Auto Scaling, it’s easy to set up application scaling for multiple resources across multiple services in just a matter of minutes.
It is a proven way to enable its flexibility by enabling an application to scale up and down to meet the requirements.
EC2 AWS Auto-scaling
Amazon EC2 Auto-Scaling helps you maintain application availability and allows you to automatically add or remove EC2 instances according to conditions you define. Dynamic scaling responds to changing demand and scaling automatically schedules the right number of EC2 instances based on demand.
Benefits of EC2 AWS Auto-scaling:
• Fault tolerance
• Availability
• Cost management
