The AWS Auto –Scaling function helps you to get the right sized IT capacity even if the actual data traffic is high or the opposite, the number of transactions are actually low. You always have the appropriate computing resources, just the capacity you need, just when you need it.
Auto-Scaling provides the proper number of EC2 (virtual compute) instances in line with the application load. By defining rules, one can add auto-Scaling Groups to his applications, and define conditions to set the minimum and maximum number of instances. Based on the given rules, AWS will manage theinstances for the application, running neither more nor less at a time than what is defined in the rules.
With the help of the autoscaling rules, you can define and control that AWS will launch the right capacity of compute resources to your business applications all the time, depending on the end user demand. The scaling can happen manually, based on rules, or in a scheduled manner. Automatic scaling has lifecycle policies, which begins with the installation of EC2 Instance and ends with manual or automatic termination (shutdown). In case of defining rules, AWS automatically launches or stops instances in order to serve efficiently and cost-optimized way the increased or decreased load demands.
It is expertise the most important criteria to develop cloud based IT. The AWS is a uniquely efficient solution, we can help you to benefit from.
