Technology and business strategy must align for success. In the era of cloud computing, cloud services are becoming essential in the areas of organisation’s infrastructure, costs, security, performance, availability, and reliability. Let’s add one more criterion to the list: cloud computing elasticity and cloud computing scalability.

What are Scalability and Elasticity?
“Cloud service elasticity is the ability to increase or decrease the amount of system capacity on demand, in an automated manner,” according to the Gartner Glossary. Elasticity in cloud computing refers to a cloud’s ability to automatically extend or compress infrastructure resources in response to a rapid increase or decrease in demand. This allows the workload to be handled effectively.
However, the phrase is frequently used in situations when a persistent resource deployment is necessary to statically manage the burden. Scalability in cloud computing may take both vertical and horizontal forms.
What Kinds of Elasticity Are There?
The two primary forms of elasticity are supply and demand elasticity. Different perspectives on elasticity include:
PED, or price elasticity of demand
It gauges how quickly consumer demand will adjust to a change in price. Alfred Marshall first proposed the idea of the PED in 1890. It is defined as the change in percentage of quantity demanded in response to a one percent change in price while other demand-determining factors remain constant.
Demand Crosselasticity (XED)
An economic concept known as “cross elasticity of demand” (XED) may quantify how responsively demand for one commodity is to changes in the prices of other commodities. It is calculated by dividing the required amount’s percentage change by the price of a single commodity. It is sometimes referred to as demand cross-price elasticity.
Demand Elasticity and Income (YED)
When the actual income of the customers is modified, it is also feasible to quantify the responsiveness in the amount demanded for an item or service. Income Elasticity Demand is the term for it. The income elasticity of demand is calculated by dividing the percent change in quantity requested by Divide the percent change in quantity requested by the percent change in income to get the income elasticity of demand. This idea aids in determining if an item is a required investment or not.
Supply Price Elasticity (PES)
It can assess how responsively an item or service’s supply is to changes in the market price. Let us explain: when a good’s price clearly declines, the supply likewise decreases; conversely, when a good’s price clearly rises, the supply rises.
In conclusion, these four different forms of elasticity evaluate how responsively supply and demand, the two primary economic variables, are to changes in other market factors.
How is Elasticity Measured?
Elasticity, as used in daily life, is a material’s capacity to restore its shape after being stretched or squeezed. Let’s utilize the huge company’s definition as a starting point for our discussion of the elasticity measurement. Elasticity in cloud computing is described by Microsoft Azure as The ability to quickly increase or decrease computer processing, memory, and storage resources to meet changing demands without having to worry about capacity planning and engineering for peak usage is referred to as “elasticity” in cloud computing by Microsoft Azure.
As can be seen, timing and demand must be taken into account when measuring elasticity.
Elasticity is frequently related to pay-per-use or pay-as-you-grow services and associated with public cloud resources. When it is not essential to pay for more resources than are used at a specific moment, this is the ideal answer for IT administrators.
What distinguishes scalability from elasticity?
Although the terms cloud computing scalability and cloud computing elasticity are frequently used interchangeably, despite how similar they may seem, the two processes are different in how they operate. Let’s contrast scalability and flexibility. The table below lists the distinctions between cloud elasticity and cloud computing scalability:

As you can see, cloud elasticity enables you to balance the allocation of resources with the demand for resources at any given time.
Everyone can picture a massive company like Amazon Web Services and its e-commerce platform, whose transaction burden rises during holidays like Christmas. Special servicing is required during this timeframe. The massive resources are no longer required after the season is over. Therefore, in this instance, it is clear that elasticity refers to the capacity to dynamically increase or decrease infrastructure resources as needed to adjust to changing workloads in a very autonomous manner while maximizing the utilization of assets.
Understanding Elasticity and Scalability in Cloud Computing is Important
In conclusion, elastic computing in the cloud enables every business to scale computing, memory, and storage capacity to suit shifting demands. Capacity planning won’t be a concern thanks to scalability measurement.
A Wakefield Research research found that 92% of organizations are either in the process of modernizing their apps or have plans to do so. According to the research, many of these modernization initiatives fail. The initiatives get riskier, more costly, and sophisticated as they advance. Experts in cloud computing scalability should focus on that area.
The smart system is essential for properly implementing cloud solutions. Although cloud elasticity and cloud scalability may differ from one another, they work best when together.
