A practitioner's guide to building scalable systems

Building Scalable Systems: Distributed Systems basics to System Design Interviews

We want to give you the tools to compare multiple approaches and pick the one that works for your scenario.

Grokking the Distributed and Scalable Systems

# What is Elasticity
When we talk about Scalability, we need to be mindful of the fact that you want an application that can not only scale up but also scale down to optimize resource consumption.

<div style="background-color:#81bd69;color:white;padding: 10px; padding-left:30px;">
Elasticity is the ability of a distributed system to adapt to the workload. An Elastic System allocates more resources to meet the increased load and then de-allocates resources when the traffic has reduced.
</div>
 

It's easier to have an elastically scalable system when you are using a cloud provider like AWS/Azure/Google etc. to run your application.

If you don't dynamically adjust the resources based on the load, you will be paying a lot in server cost for capacity that will remain idle except for a few hours each day during the peak hours.
