Start the high-level design by specifying one to two metrics (e.g. number of users added, products sold before vs after a feature launch, etc.). Then use these metrics to do some simple calculations in order to find the optimal usage pool of the system. This question frequently appears as "Design Uber", "Design DoorDash", etc., substituting in whichever brand is prominent in the region you're interviewing in. If you were interviewing at Google this question would probably be presented as "Design Google Drive" whereas elsewhere it might be "Design Dropbox."

Be sure that you fully understand the question before moving forward. If not, you might want to use our free tech resume guide (with examples) to improve your resume. Get to know the Hardware Virtual Machine (HVM) for superior performance. Show off your technical skills and impress interviewers with your AWS tool know-how.
The process
APIs are kind of like the bridges that connect the roads of major software products. As a result, they are a central part of the system design of major apps like Instagram, YouTube, Twitter, etc. URL shortening services like TinyURL, Bitly, etc. provide short link aliases that redirect to longer URLs. Here are some points of consideration to help you work out how to build this kind of system. Some of the above considerations were inspired by this in-depth solution to the question, so feel free to check out that resource. Let’s walk through an example of how you could approach the problem if you were asked to design a chess game.
Is Nginx in AWS a hosting server?
We’re here to help you navigate through the chaos and master those specific features that will make you shine in an AWS system design interview. So, let’s dive in and explore these features within the broader context of cloud computing architectures, scalability strategies, and system reliability. The second online assessment (OA2), is a set of two data structure and algorithm questions. Each question needs to be solved within a certain amount of time (e.g. 30mins).
Bridging public and private clouds, hybrid solutions offer a variety of options for those looking to leverage the advantages of multiple cloud providers. Knowing how each model works will give you the power to tailor your solutions like a pro. Visualize constructing a messaging system capable of managing millions of users without any difficulty. To tackle this, you’ll need to talk about load balancing strategies using Elastic Load Balancer (ELB) and auto-scaling groups. One of the main challenges of coding interviews is that you have to communicate what you are doing as you are doing it.

It is okay to change some components at this stage if you think it will improve the system, but you must explain to the interviewer what you are doing and why. The questions below are organized by company, to help you find the most relevant ones for your interviews. For a full answer to this question, take a look at the video guide below by Naren from Tech Dummies. You'll need to design a system that can scale to millions of users and handle petabytes of data.
In the IT world, good communication means more than just talking smart. You need to explain complex ideas in simple terms, especially to non-tech folks. Improving these skills will make you a pro at interviews and boost your chances of success.
Scalability and Performance
Think data consistency across regions with RDS replication techniques or tackling network latency with Route 53’s DNS routing. This is the part of the interview where you want to show that you can both be creative and structured at the same time. In most cases, your interviewer will adapt the question to your background.
You should practice a lot for coding and design interviews and get to experience a practice interview before the real thing. The mock interview will help level up your skills and calm your nerves. I recommend you to use our peer-to-peer mock interviews platform for LeetCode and System design preparation. With proper preparation and some practice, system design interviews can be much easier than people expect.
Finally, a great way to practice coding, system design, and behavioral questions, is to interview yourself out loud. This may sound strange, but it will significantly improve the way you communicate your answers during an interview. Well-preparation is a ‘must’ if you want to crack the system design interview and land a job offer in this top tech company.
By having multiple servers running the same application, a system can continue to operate even if one server goes down. Additionally, the use of automated failover mechanisms can help to ensure that a system remains operational even in the face of unexpected failures. It's important to communicate your thought process and reasoning behind your design decisions effectively. You'll need to explain your approach and reasoning behind your design decisions to the interviewer. Before wrapping up the round, take about five minutes to re-examine what you’ve designed. Does it meet the objectives you laid out with the interviewer at the beginning of the session?
This exceptional deal on IT training provides you access to high-quality IT education at the lowest monthly subscription rate in the market. Boost your IT skills and join our journey towards a smarter tomorrow. It’s also a test of your communication and strategic thinking abilities. Being able to upgrade or downgrade with near-zero downtime is a valuable skill that impresses employers. Think strategically about how different technologies fit into larger systems architecture contexts. To ace it, use a repeatable answer framework that tackles different aspects of the problem at hand.
