I used to think that reading would make me wise. One day, ten pages before finishing a book, I realized that I had read that same book before. At that point, my perspective on reading and, therefore, my life had changed. Now, I don’t care how many books I read; I take many notes, connect dots, and share what I’ve found on my blog and newsletter. I’m interested in many things at the same time (I’m a multipotentialite). On this blog, you’ll find me talking to about multiple aspects of life like leadership, software engineering, philosophy, psychology, software architecture & design, urban & industrial design, exercising, finance, Formula1 Racing, eating healthy, and many more. I’m a software engineering manager; that’s my current job. At home, I’m a writer and an avid reader. I rarely watch TV, movies or TV series. I don’t have any social media account (except Mastodon where I have automated posting of my new articles). Hence, I often miss the popular culture references in conversations. That’s alright. I don’t have FOMO; I embrace JOMO. I rarely read fictional books.

There are two methods of scaling (a dichotomy): scaling up (vertical scaling) and sealing out (horizontal scaling). Although neither is a silver bullet, implementing either one or a combination of two is often the right action. Choosing...

Besides load, we have to understand the performance of the system before trying to scale the application. We use performance metrics. These metrics vary in different systems. In batch processing systems, it is throughput (the # of...
To talk about increasing load and scalability, we first need to define the system's current load. There is no one way of doing it as it depends on the project and its architecture, but we use load parameters. These parameters will be...
Defining the system load and performance is important to understand scalability. Scalability is the system's ability (performance) to cope with increased load. The load doesn't say anything when it's used alone. The load can be anything,...
The size of the project matters a lot in the diseconomy of scale. In Software Estimation, Steve McConnell talks about estimating projects on different scales and considering important factors. Typically, we talk about economies of scale...
In hash partitioning, we use hash functions for ranges to distribute data evenly between partitions. The range-based partitions still have the disadvantage of loading one partition with more data. With hash functions, we solve this...
Elasticity is a service’s ability to handle bursts of traffic. It’s often confused with scalability. Scalability is the ability to handle a large number of concurrent requests. Although these two are different, elastic systems also need...
