Zoom scaled from 20 million to 300 million users virtually over night. What's incredible is from the outside they've shown little in the way of apparent growing pains, though on the inside it's a good bet a lot of craziness is going on. Sure, Zoom has made some design decisions that made sense as a small spunky startup that don't make a lot of sense as a defacto standard, but that's to be expected.

Selenium is an open-source automation framework initially introduced in 2004. Using this framework, we can validate web applications across different browsers and platforms. Java, C#, Python are mostly used for developing test scripts. Testing performed using Selenium are generally referred to as Selenium testing. The initial version released is just a single tool, but the latest version is now not only a tool — it’s a software suite with a pack of IDE, RC, and WebDriver.

It can scale towards a multi-petabyte level data workload without a single issue, and it allows access to a cluster of powerful servers that will work together within a single SQL interface where you can view all of the data. In this blog post, we explain what Greenplum is, and break down the Greenplum architecture, advantages, major use cases, and how to get started.

MySQL does not limit the number of slaves that you can connect to the master server in a replication topology. However, as the number of slaves increases, they will have a toll on the master resources because the binary logs will need to be served to different slaves working at different speeds. If the data churn on the master is high, the serving of binary logs alone could saturate the network interface of the master.

The software testing team uses bug tracking software's to keep a track of bugs and to report them as the program is being tested.
