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. Load balancers can detect when a component is not responding and put traffic redirection in motion.

Among the different components of modern software solutions, the database is one of the most critical. Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors. For storage, FIO is generally used. Database: MySQL 8.0.31

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.

Some of the most important elements include: No single point of failure (SPOF): You must eliminate any SPOF in the database environment, including any potential for an SPOF in physical or virtual hardware. Load balancing: Traffic is distributed across multiple servers to prevent any one component from becoming overloaded.

This often happens out of an ad-hoc virtual team that forms in earlier stages but is now formalised and has long-term staffing. Teams can quickly regress from Level 4 maturity through turnover.
