Overview of the Elasticity Approach

The flexible approach emphasizes that price fluctuation is a determinant of the national balance of payments and exchange rate

Elastic methods help you to understand the various outcomes that can occur in the short term and long term.

Demand price elasticity is a measure of the reactivity of demand to price change.

Demand is relatively resilient if demand is very sensitive to price fluctuations.

If demand is not very sensitive to price fluctuations, demand is not relatively resilient.

Domestic goods will be relatively cheap if the currency of a country goes down, but overseas markets will be relatively expensive in the world market.

For this reason, the flexible approach takes into account the import / export response to changes in the value of the currency of a country.

For example, if the resilience of import demand is very high, depreciation of the local currency will result in an imbalanced decrease in domestic imports.

Foreign exchange supply of a country depends on its import requirements (especially) at the time of import of the country, such as providing foreign exchange as payment.

For example, if a country exports, that country needs foreign exchange as a payment.

If the amount of foreign exchange provided is equal to the necessary amount, the current account is balanced

Superscripts I and E show relatively inelastic and relatively elastic supply and demand curves.

According to the spot exchange rate of S 0, the current account deficit occurs frequently because the country's foreign currency supply is excessive.

If foreign exchange demand and supply is not comparatively flexible, it is necessary to make a substantial change in spot exchange rate.

With a flexible approach, the trade balance adjustment pass is based on the elasticity of import and export demand. Demand elasticity is defined as the quantitative response of demand goods or services to price fluctuations. Although the elasticity method is often called the Bickerdike-Robinson-Metzler condition, in fact Bickerdike was originally developed method, and by modeling nominal import and export prices as a function of import and export volume, this approach We have laid the foundation. Later Robinson and Metzler contributed to a flexible approach by clarifying Bickerdike's new concept and explaining in detail.

Resilience is a fundamental attribute of cloud computing and recently witnessed important development. This article outlines conventional and recent resilience solutions and outlines containerization, a trend of new technologies for lightweight virtualization. In addition, I will explain the main problems and research subjects related to resilience of cloud computing. Comprehensively confirm and analyze the recommendations made in this field. Provide flexible mechanism classification based on identified work and key attributes. Compared with other literature studies, this paper has conducted a wider and more detailed analysis of the elastic method which is considered to be the initial investigation on container elasticity.

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
