Customers use one of the company's websites to manage and check the status of their newly registered users. This website is deployed to virtual machines and hosted on-premises. their team noticed that increased usage on the site is straining the machines resources. However, they can't adjust to load fluctuations without manually intervening and creating or deallocating virtual machines.

Customer decides to move the application to Azure. Customer need a solution that automatically handles load fluctuations and ensures consistent performance of the website. Customer also need to quickly roll out application updates to the servers while minimizing the effect on end users.

Solution

Virtual Machine Scale Sets in azure can be used to handle the usecase

   maximum no.of Instances : How many Machines that customer want atmost to handle/avoid load fluctuations
   
   In Scale Out sub section:
   CPU Thresold:at what percentage the instances count should increases to handle Load
   No of instances increased should be chosen interms of consistent performance of website

4. In Scaled In Sub Section:
   CPU Thresold:at what % of CPU ,the instances count should be decreased because of reduction in traffic and how many instances should be reduced can be done in the view of ensuring consistent performance of the Application.
5. remaining sections are filled accordingly in such a way that customer fulfilled his/her requirements and finally deploy the VMSS




6. After completion of deploying the Virtual Machine Sccale Set ,The Application should be deployed in VMSS. whenever Customer needs requirements ,based on customer ,configurations will be changed in VMSS.
