Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. It also supports the flexibility and scalability of the database infrastructure.

Software testing is the process of finding bugs or discrepancies in a software. Even though the job of a software tester is to catch errors committed by developers, software testers themselves are not immune to errors. Introduction. Few Common Testing Mistakes.

Let’s start with this: MongoDB is accurately referred to as source-available software. Many open source proponents, including the Open Source Initiative (OSI) , do not consider software under the SSPL to be open source. We agree with the OSI’s determination that any software under the SSPL cannot be open source.

Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. In the context of web development, performance testing entails using software tools to simulate how an application runs under specific circumstances.
