Cloud Scalability Vs Elasticity: A Simple Overview In 4 points


When a company decides to take up cloud services for its infrastructure, many things should be considered. The cost, availability, reliability, and performance are among a few of them. Apart from these significant areas of concern, scalability vs elasticity need proper consideration too. These terms might have been confused with each other many times, but understanding the difference between them is very important.

  1. Scalability vs Elasticity
  2. Cloud Elasticity
  3. Cloud Scalability
  4. Difference between Scalability vs elasticity

1. Scalability vs Elasticity

The main aim of cloud elasticity is to ensure that the resources are sufficient at every given point in time. Cloud scalability, on the other hand, manages the needs that keep on changing with time. This is done by adding or deleting the resources to ensure that resources are neither lacking nor available in excess. Scalability vs Elasticity shall be discussed in detail.

But before that, We shall now discuss each of them in detail, one by one.

2. Cloud Elasticity

In simpler terms, not owing to Cloud services, elasticity happens to shrink and extend itself depending on the surroundings’ condition. In other words, it is the ability to adapt to the surroundings. Similar is the case when we talk about Cloud elasticity. Ensuring that sufficient resources are available is what its primary focus stays on. All this, in turn, results in cost-cutting within the organization. But it’s often said that to gain from elasticity is not everyone’s cup of tea, or it does not work in all work environments.

To be more specific, work culture where changes do not occur rapidly tends to have minimal or no advantage of Cloud elasticity. To utilize the services of something that works dynamically, it is somewhat more important for the organization to be dynamic. Cloud elasticity is also associated with solutions that are supposedly scaled out for allowing the resources to get added or deleted dynamically.

Pay as you grow services have been believed to be associated with the concept of elasticity in cloud computing. The necessary funds are that the company is neither paying more nor spending less. The resources that are required to be paid, others that are not, are left unpaid.

Let us understand the concept of Cloud elasticity with an example. The example would also let you understand the concept of scalability vs Elasticity clearly. As mentioned earlier, Cloud elasticity works the best in a dynamic work environment like those businesses with seasonal offerings for the clients. Like the clothing, the business would take a sudden hike in the holiday or Christmas season. For the companies at that time, it is crucial to increase resource availability, which would last for a lesser period. The resources need to get back to the original after the season is over.

3. Cloud Scalability

Scalability in cloud computing refers to increasing the workload within an existing limit of hardware or software without applying any negative impact on the performance. Cloud scalability works in two different ways. It can either be horizontal or vertical. The applications within the infrastructure have room to expand or shrink according to the demand. In these scenarios, the manager is well aware that once the resources’ request lowers down, they will scale out and get back to normal. When the resources are much more than required, they are made to scale out until the demand arises again.

Let us take an example to understand the concept properly. A small-scale business had a server supporting its database. With time, the company expanded, and the demand for resources rose as well. When the manager knows, depending upon the growth that the business experienced, he needs the expansion to be done in terms of the available resources. This is when Cloud scalability comes into play. The company would, therefore, be ready for any scale performance with the process of cloud scalability.

4. Difference between Scalability vs elasticity

While scalability vs elasticity needs to be considered, there are some similarities that need to be highlighted too. Both of them are adaptable solutions for organizations, but they have specific differences. While elasticity works in those work environments with dynamic working conditions, elasticity does not need any such criteria to work upon.

On the one hand, where elasticity works well in public cloud environments, stability has been known to work the best in private cloud environments. Most of the time, they are confused amongst each other once the concept is taken into consideration. The differences can be sought out very quickly.

Cloud elasticity and scalability optimize the infrastructure and ensure that the organizations keep up to the compliance levels. Right-sized infrastructure is also something that these two bring along.


Cloud services have a lot to know about. Its two features, Cloud elasticity and Cloud scalability, manage to keep the resource intact. Those two ensure that the resources are neither lacking nor getting wasted in anyways. The working patron of the two is different, but both share a similar motto at the end of the day.
