Scalability and elasticity.

What are scalability and elasticity?

Scalability and elasticity describe two processes that are continually tested in product management and which make for project longevity. 

Elasticity measures the ability of the team to match resources within the allocated actual amount of resources needed. This means that the product is ‘elastic’ enough to do what is needed, given the circumstances and available resources.

Scalability, in turn, is something different. It measures the changing needs of an application within the confines of an infrastructure, adding or removing resources to meet the application's demands. Compared with elasticity, which measures resource allocation, scalability measures how far the product or application can grow or shrink to meet demands. This ensures the product can scale up or down to handle different workloads and maintain consistent performance.

Why would you want scalability and elasticity testing?

 With the increasing complexity and variability of workloads, it is essential to have a testing infrastructure that can scale up or down as needed to maintain consistent performance. A certain amount of ‘give and take’ allows for the way users will access your product differently, as well as their use of it and the volume of users that track through your product.

By creating a scalability and elasticity process for cloud application testing, project managers can improve testing efficiency, reduce testing costs, and ensure that applications are thoroughly tested under various conditions.

How does scalability and elasticity testing work?

Scalability and elasticity can be used in the following ways to measure performance and performance indicators worth tracking. The systems should be used to:

  • Identify the key performance indicators (KPIs) we want to monitor and measure.
  • Set up a testing infrastructure that can automatically scale up or down to handle different workloads.
  • Establish clear testing procedures and protocols to ensure tests are executed consistently and accurately.
  • Use data analytics to optimize the testing infrastructure and improve testing efficiency.
  • Conduct regular performance testing to identify potential bottlenecks and areas for improvement.
  • Use load testing to simulate realistic workloads and identify the limits of the testing infrastructure.
  • Use auto-scaling groups to automatically add or remove testing resources based on demand.
  • Implement elasticity policies to adjust the capacity of the testing infrastructure based on workload.
  • Use cloud-native tools and services to improve the efficiency and scalability of the testing infrastructure.
  • Continuously monitor and evaluate the effectiveness of the scalability and elasticity process, and make improvements as needed.

The value of scalability and elasticity

Scalability and elasticity processes help plan for the now and the long term. While you may be happy with the current usage of your product and cloud network, it’s important to foresee how things might change and scale to meet that change. It’s also important to have contingency plans in play if things don’t pan out as planned.

Main advantages of scalability and elasticity

  • Creates a plan ahead of time
  • Allows lead way for the success or product reluctance 
  • Works with internal project management planning
  • Helps set goals for the project
  • Allows you to design cloud architecture ahead of time

A common user story

“As a Product Manager, we want to create a scalability and elasticity process for cloud application testing to ensure that our testing infrastructure can scale up or down to handle different workloads and maintain consistent performance. By identifying key performance indicators, setting up a testing infrastructure that can automatically scale up or down, establishing clear testing procedures and protocols, and using data analytics and machine learning to optimize the testing infrastructure, we can improve testing efficiency, reduce testing costs, and ensure that our applications are thoroughly tested under a variety of conditions. This can help us to deliver high-quality applications more quickly and reliably.”
