Turning data into meaningful insights and clear communication — Introduction: The Importance of Data in Storytelling In the era of Big Data, the ability to extract valuable insights from massive amounts of information has become an essential skill. But what happens after you’ve conducted your analysis and identified a significant trend? How do you effectively share that insight with others? The next, and perhaps most crucial…

A Look into a Memorable Marketing Campaign: Spotify’s “Wrapped” 2019 — The world of product marketing management (PMM) often revolves around creative and data-driven strategies. One intriguing question often posed to PMMs is: “What is your favorite marketing campaign, and why?” A noteworthy response to this question is the appreciation of Spotify’s “Wrapped” campaign of 2019. Spotlight on Spotify’s ‘Wrapped’ Campaign

Queues are used to manage requests in a large-scale distributed system effectively. — In small systems with minimal processing loads and small databases, writes can be predictably fast; however, in more complex and large systems, writes can take an almost non-deterministically long time. For example, data may have to be written on different servers or indices, or the system could be under high…

Redundancy means duplicating critical data or services to increase the system's reliability. — For example, if only one copy of a file is stored on a single server, then losing that server means losing the file. Since losing data is seldom a good thing, we can create duplicate or redundant copies of the file to solve this problem. This same principle applies to…

A proxy server is an intermediary piece of hardware/software that sits between the client and the back-end server. — It receives requests from clients and relays them to the origin servers. Typically, proxies filter requests, log requests or sometimes transform requests (by adding/removing headers, encrypting/decrypting, or compression). Another advantage of a proxy server is that its cache can serve many requests. …

Indexes are used to improve the speed of data retrieval operations on the data store. — An index makes the trade-offs of increased storage overhead and slower writes (since we have to write the data and update the index) for the benefit of faster reads. Indexes are used to quickly locate data without examining every row in a database table. …

Data partitioning (also known as sharding) is a technique to break up a big database (DB) into many smaller parts. — It is the process of splitting up a DB/table across multiple machines to improve an application's manageability, performance, availability and load balancing. …

CAP theorem states that it is impossible for a distributed software system to simultaneously provide more than two out of three of the following guarantees (CAP): Consistency, Availability and Partition tolerance. — When we design a distributed system, trading off among CAP is almost the first thing we want to consider. CAP theorem says while designing a distributed system, we can pick only two: Consistency

By definition, Design Patterns are reusable solutions to commonly occurring problems(in the context of software design). — Design patterns were started as best practices repeatedly applied to similar problems encountered in different contexts. They became popular after they were collected, in a formalized form, in the Gang Of Four book in 1994. Originally published with C++ and Smalltalk code samples, design patterns are very popular in Java…
