The <strong>Maximum, Minimum<\/strong> and the <strong>Desired<\/strong> capacity will defined initially e.g. via the Management Console. If for example two instances fail, EC2 Auto Scaling Group is able to rebuild two new instances as a replacement. The replacement is also well balanced between the <strong>Availability Zones<\/strong> (Above AZ1 vs. AZ2). <br><br>The capacity could be set as a conditional and\/or scheduled capacity demand in relation to the calendar and scaling in or out is possible. Typically a Auto Scaling group is placed beneath a <strong>Load Balancer<\/strong> or behind a queue. The Load Balancer delivers traffic into an Auto Scaling group and we could use measurements from Load Balancer to manage better the Auto Scaling group. Optionally the usage of <strong>CloudWatch<\/strong> supports the monitoring of the Auto Scaling metrics in a centralized component as well.<\/p>\n\n\n\n<figure class=\"wp-block-image is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/customers-love-solutions.com\/wp-content\/uploads\/2019\/11\/20191017-AWSOMEDAY2019_2.2EC2_AutoScaling2-ELB-1024x232.jpg\" alt=\"\" class=\"wp-image-800\" width=\"716\" height=\"162\" srcset=\"https:\/\/customers-love-solutions.com\/wp-content\/uploads\/2019\/11\/20191017-AWSOMEDAY2019_2.2EC2_AutoScaling2-ELB-1024x232.jpg 1024w, https:\/\/customers-love-solutions.com\/wp-content\/uploads\/2019\/11\/20191017-AWSOMEDAY2019_2.2EC2_AutoScaling2-ELB-300x68.jpg 300w, https:\/\/customers-love-solutions.com\/wp-content\/uploads\/2019\/11\/20191017-AWSOMEDAY2019_2.2EC2_AutoScaling2-ELB-768x174.jpg 768w, https:\/\/customers-love-solutions.com\/wp-content\/uploads\/2019\/11\/20191017-AWSOMEDAY2019_2.2EC2_AutoScaling2-ELB-594x134.jpg 594w, https:\/\/customers-love-solutions.com\/wp-content\/uploads\/2019\/11\/20191017-AWSOMEDAY2019_2.2EC2_AutoScaling2-ELB.jpg 1140w\" sizes=\"auto, (max-width: 716px) 100vw, 716px\" \/><\/figure>\n\n\n\n<p><em>Return to main post of AWSOMESDAYS 2019 agenda<\/em>? <br>Click here <a href=\"https:\/\/cutt.ly\/GeYaUS9\">https:\/\/cutt.ly\/GeYaUS9<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fleetmanagement, EC2 Auto Scaling.
