We have collected several topics that you might ask - why not read it and get rid of uncertainty before you get out of the door?
Question 1: What exactly is AWS,
and why should a professional know their way around it?
Sprintzeal is one of the basic AWS interview questions that are often used as a kind of introduction to the topic. It is also a great opportunity to show your knowledge of the current situation in the cloud computing market and the relevance of certain technologies, so use wisely.

Some AWS interview questions that you hear can be associated with the system's global infrastructure. For a true specialist, it's not a brainer - and yet, many people stumble because they don't know how to describe something appropriately.
Simply put, a region defines a geographical location that has two or more availability zones and even more edge locations. The availability zone is basically a data center that is in the hostage server and other systems needed for service use, and the location of the edge is used to cache the content in various locations so that it can be downloaded faster. In 2021, there were 24 areas launched, 77 availability zones, and more than 200 edge locations around the world - moreover, there have been plans for expansion.
Extensive global infrastructure means more countries can use services, and Amazon constantly work on increasing their accessibility - however, you also have to know that new services are gradually introduced and not immediately available in all regions equally.

This is important for any company that provides services that depend on location or just wants to adjust their content to suit their customers' needs better. For example, for example, special offers are only available for residents of certain countries. In this case, e-shop can only show relevant information to people in the right location and avoid confusing their users in other countries.

your expenses for AWS?
