Question 2 of 30

Here at Uber, we prefer to design applications which will scale to accommodate our growth. What methodologies do you use to ensure that your program will scale?

"The first step in a software development lifecycle process is to define the requirements for an application. During this phase, I would inquire with the Uber project stakeholders about the possibility of the operation related to the program expanding or growing and the need for the program to scale. Once I confirm this need, I'd then go about developing a program with scalable features. The methodologies I use to accomplish this include using microservices instead of a monolithic architecture, assigning the appropriate caching, queues, databases, and selecting the appropriate development language and deployment platform. Languages I prefer for scalable programs include Ruby and Django if it is a web application. I'm also more inclined to develop the application to run on a cloud platform which provides the greatest flexibility and scaling."

  • 2. Here at Uber, we prefer to design applications which will scale to accommodate our growth. What methodologies do you use to ensure that your program will scale?

      How to Answer

      Creating programs that scale is a critical skill in today's fast-changing business environment. Businesses like Uber need appropriate applications for their current size and activity level but can grow as the business grows. Developing scalable programs saves the business money during the initial development cycle. Also, it prevents them from reprograming the applications or adopting new ones when the business activity increases beyond the capability of the current program. Your answer to this question should discuss the specific techniques and methodologies you use to accomplish this objective.
