What is the difference between auto scaling and load balancing?

Load balancing evenly distributes load to application instances in all availability zones in a region while auto scaling makes sure instances scale up or down depending on the load.

What is the default cooldown period in auto scaling?

300 seconds(The default is 300 seconds.) This gives newly launched instances time to start handling application traffic. After the cooldown period expires, any scaling activities that are triggered after the cooldown period can resume.

What is the difference between horizontal and vertical scaling?

With vertical scaling (a.k.a. “scaling up”), you’re adding more power to your existing machine. In horizontal scaling (a.k.a. “scaling out”), you get the additional resources into your system by adding more machines to your network, sharing the processing and memory workload across multiple devices.

What is auto scaling in Azure?

Which of the following are the options for auto scaling?

These resources include Elastic Compute Cloud (EC2) Auto Scaling groups, Amazon Elastic Container Service (ECS) components, EC2 Spot Fleets, DynamoDB global secondary indexes or tables, and Aurora replicas or clusters.

Which type of scaling does AWS Auto Scaling provide?

AWS Auto Scaling makes scaling simple with recommendations that allow you to optimize performance, costs, or balance between them. If you’re already using Amazon EC2 Auto Scaling, you can now combine it with AWS Auto Scaling to scale additional resources for other AWS services.

What do you mean by scaling?

Definition: Scaling is the procedure of measuring and assigning the objects to the numbers according to the specified rules. In other words, the process of locating the measured objects on the continuum, a continuous sequence of numbers to which the objects are assigned is called as scaling.

What is target value in AWS Auto Scaling?

With target tracking, you select a load metric for your application, such as “Average CPU Utilization” or the new “Request Count Per Target” metric from Application Load Balancer, set the target value, and Auto Scaling adjusts the number of EC2 instances in your Auto Scaling group as needed to maintain that target.

What are Auto Scaling groups?

An Auto Scaling group contains a collection of Amazon EC2 instances that are treated as a logical grouping for the purposes of automatic scaling and management. An Auto Scaling group also enables you to use Amazon EC2 Auto Scaling features such as health check replacements and scaling policies.
