Elasticity

Elasticity is an indicator of how sensitive a given variable is to another variable. In business and economics, resilience is the amount by which individuals, consumers, or producers change their needs or respond to price and income changes. It is mainly used to evaluate changes in consumer demand caused by changes in prices of goods and services.

An elasticity value greater than 1 indicates that the demand for goods or services is affected by the price. A value less than 1 indicates that the demand is not dependent on the price.

Resilience is an economic concept used to measure changes in the total amount of goods or services related to price fluctuations of goods or services. If the quantity demand changes dramatically as the price of the product rises or falls, the product is considered resilient. Conversely, if the demand for the product does not change much when the price fluctuates, the product is considered to be inelastic.

For example, insulin is a very elastic product. For diabetic patients requiring insulin, the demand is so great that the impact of price increases on demand is small. Price reduction does not affect demand; most people who need insulin do not persist at lower prices and are already buying

The other side of the equation is a very elastic product. For example, a bouncing ball is very elastic. Because they are not mandatory, consumers only decide to buy at a lower price. Therefore, when the price of the bouncing ball goes up, the necessary amount decreases greatly, and as the price goes down the necessary amount increases.

Understanding whether the company's products or services are resilient is a necessary condition for the company's success. Companies with high resilience will ultimately need a large number of sales transactions to compete with other companies and maintain solvency. Meanwhile, companies with inflexibility have products and services essential to enjoying the luxury of setting higher prices.

In addition to the price, the elasticity of goods and services directly affects the customer retention rate of the company. Companies often struggle to sell unfamiliar goods and services, so doing so keeps customers faithful and continues to purchase goods and services even as prices rise.

This elasticity measure is sometimes referred to as the price elasticity of demand for goods, that is, the elasticity of the demand against the price of the product itself, so as to distinguish it from the elasticity of demand of goods. Price change of other goods, that is, supplementary goods or alternative goods. The latter elastic indicator is called cross-price elasticity of demand. As the difference between the two prices or quantities increases, the precision of the PED given by the above equation is reduced by a combination of the two reasons. First, the PED of goods is not necessarily constant, and as stated below, due to its nature of the percentage, PED can change at different points in the demand curve. Elasticity is different from the slope of the demand curve, which depends on the unit used for price and quantity.

The relative responsiveness of the change in demand (Q) to a specific change in unit price (P) is the so-called demand price elasticity, also called PED or price elasticity. In this article we introduce the basic principles of price elasticity theory, then get out of the classroom and return to the real world (although it is slightly disarrayed, Uber's surge pricing model). possibility

Resilience is one of the most important benefits of cloud computing. Flexibility is to tailor your ability to your needs as much as possible. Every element of the architecture is not resilient, but the architect must recognize the importance of resilience and make efforts to use it at every opportunity. In modern clouds, adding additional computing / network / storage (vertical scaling) to existing servers is an easy task. But the ultimate performance and real cost constraints. In terms of scalability, cost, and resiliency, it is recommended to distribute the load among auto expansion groups that add / remove small instances. Your architect should instinctively establish a horizontal ratio from the beginning
