💡 System Design Interview: mini Twitter
How would you design Twitter? It’s essentially the same question as designing Facebook, Linkedin, or many other social media services. The key scenario in question is usually that a user can follow or unfollow other users. Any user can tweet stuff. A user should be able to see tweets, displayed in a certain order, from the users she is following — the so-called timeline. And the core discussion point is designing for scale.

System Design Interview: Replicated and Strongly Consistent Key-Value Store
Designing a replicated and strongly consistent key-value store, which sounds seemingly simple, is actually quite a tricky interview question. You’d need to have a good understanding of some of the distributed systems concepts to be able to answer this question well. If you’re not in a domain specific interview, for this kind of questions, chances are that the interviewer just wants to observe how well you can navigate through a complex design problem. In that case, the discussion itself is usually more important than the final solution.

🔐 The Next Gen Database Servers Powering Let's Encrypt
Let’s Encrypt helps to protect a huge portion of the Web by providing TLS certificates to more than 235 million websites. A database is at the heart of how Let’s Encrypt manages certificate issuance. If this database isn’t performing well enough, it can cause API errors and timeouts for our subscribers. Database performance is the single most critical factor in our ability to scale while meeting service level objectives. In late 2020, Let's Encrypt upgraded the database servers and they’ve been very happy with the results.

Toy solutions solving Twitter’s “problems” are a favorite scalability trope. Everybody has this idea that Twitter is easy. With a little architectural hand waving we have a scalable Twitter, just that simple. Well, it’s not that simple as Raffi Krikorian, VP of Engineering at Twitter, describes in his superb and very detailed presentation on Timelines at Scale.

How to Design a Scalable Rate Limiting Algorithm
Rate limiting protects your APIs from inadvertent or malicious overuse by limiting how often each user can call the API. Without rate limiting, each user may make a request as often as they like, leading to “spikes” of requests that starve other consumers. Once enabled, rate limiting can only perform a fixed number of requests per second. A rate limiting algorithm helps automate the process.

A Scalable Prefix Search Service for Powering Autocomplete
If you’ve ever googled something, you probably take it for granted that suggestions appear based on what you’ve typed so far. Yet, these suggestions are an essential part of the googling experience. It would almost feel more weird if you were typing out a search query and autocomplete suggestions did not show up.
Indeed, Google’s autocomplete is powerful and useful, so it’s no surprise that there are many open source implementations of autocomplete widely available.

💡 System Design Interview: Rate limiter and Data modelling
More often than not, the design interview rounds start with basic questions such as “design a rate limiter” or “design a circuit breaker” and can go to much more depth based on your experience. The questions posed can be to design an existing technology or any specific use case of the company you’re interviewing for. Sometimes these questions get asked in telephonic screening which is an elimination round and decides whether a person’s candidature should be taken forward or not; Along with the design, one might be asked for data model to the solution or even code it up.
