Auto Scaling is used for automatic scaling up and scaling down. <\/span><\/i>
\n<\/span><\/i>Load balancer is used to distribute the incoming traffic across multiple targets. <\/span><\/i>
\n<\/span><\/i>We will be discussing these two concepts in detail in the following article.<\/span><\/i><\/p>\n

When you launch a business application, you want it to reach as many users as possible, right?\u00a0<\/span><\/p>\n

But how many people your application can serve at one time depends on its server\u2019s technical capacities.\u00a0<\/span><\/p>\n

Let\u2019s understand this concept with an example. Say, your launch an application where you feel the daily user traffic will be around 10,000 visitors. Thus, you invest in a server that can deal with 10,000 visitors with ease.\u00a0<\/span><\/p>\n

But let\u2019s say one of your marketing campaigns performs really well. And more than 15,000 visitors flock to your app at once. That would cause hindrances in user experience as the server would have maxed out on its capacity. In such a situation, you\u2019d require a server with higher capacity.\u00a0<\/span><\/p>\n

Of course, one simple option is for you to upgrade your server. That, however, has two issues –\u00a0<\/span><\/p>\n

    \n
  1. Till the time you are notified of the problem and till the time you upgrade the server, your application\u2019s user experience would remain poor. A lot of people will have negative experiences with your app\/site and they may never come back.\u00a0<\/span><\/li>\n
  2. After the buzz from the campaign dies, the traffic would come down to the usual, and then your extra server capacity would remain idle, while you are still billed for it.\u00a0<\/span><\/li>\n<\/ol>\n

    In such situations, AWS servers offer you 2 unique solutions to automatically scale up and down your server and balance the load.<\/span><\/p>\n

    These two solutions are –\u00a0<\/span><\/h3>\n
