AWS autoscaling is a necessity for cloud-based applications. Do you know how to use it to ensure the availability and efficiency of your business?  

Imagine the following situation... You have an application that needs to be available 100% of the time, but an unexpected volume of traffic hits it and you have no way to scale it immediately. Result? Chaos. Users are irritated by the instability, you lose potential customers and credibility in the market. Not to mention profit flying out the window: this could have been avoided with AWS autoscaling .

What is autoscaling ?

Autoscaling AWS is a service from Amazon Web Services (AWS). Its objective is to automatically monitor and adjust the capacity of its servers on demand, maintaining the high performance of applications hosted in the cloud. In this way, AWS autoscaling allows you to scale your application as needed, at no additional cost. When the peak traffic drops, your servers will revert to their default configuration.

What is autoscaling ?

AWS autoscaling can be used to:

  • Automatically manage your Amazon Elastic Compute Cloud (EC2) ;
  • Maintain the appropriate number of instances for your applications;
  • Operate a healthy group of instances;
  • Scale on demand, that is, according to your needs.

Why autoscaling important?

It is common for internet-based applications to have traffic patterns: seasonal peaks, stability or growth over a given period. Whatever the case, this requires your applications to scale appropriately to meet customer demand. Cloud-based, AWS autoscaling lets you do this automatically. Among its advantages is the possibility of defining capacity parameters that control the amount of traffic that triggers new servers.

AWS autoscaling is also a good way to take the pressure off entrepreneurs and product developers. After all, now they don't have to worry about guessing and planning the application's load capacity in advance.

Do I need autoscaling ?

Have you read recommendations about AWS autoscaling but still not sure if you need it? Here are some scenarios where this solution can help you:

  • If you have instances serving a business-impacting application, AWS autoscaling ensures high availability;
  • If your instances become insufficient, AWS autoscaling automatically scales and scales as needed;
  • If you would like your instances to be distributed to maximize the resiliency of your applications, AWS autoscaling can do that for you;
  • If your solution is subject to consumption peaks on the retail calendar, for example: Black Friday , Christmas, Mother's Day, etc.

How does autoscaling ?

Through AWS autoscaling , you can set up a unified scaling policy, add scalable resources, and define how they should scale. Within the dashboard , you can choose to prioritize application availability, cost optimization, or a combination of the two.

AWS autoscaling also provides recommendations for tuning policies based on metrics popular with Amazon Web Services (AWS) users In addition, it allows you to view resource utilization across different services in a single user interface.

While it's free, the resources it scales or the services it uses are charged.
