Also, in general terms, a high availability PostgreSQL solution must cover four key areas: Infrastructure: This is the physical or virtual hardware database systems rely on to run. Without enough infrastructure (physical or virtualized servers, networking, etc.), there cannot be high availability. If so, what are the legal liabilities?

MySQL, PostgreSQL, MongoDB, MariaDB, and others each have unique strengths and weaknesses and should be evaluated based on factors such as scalability, compatibility, performance, security, data types, community support, licensing rules, compliance, and, of course, the all-important learning curve if your choice is new to you.

Let’s face it – the ideal load test emulates real world traffic, yet most load testing software doesn’t come close. Today we’ll be reviewing LoadView , an on-demand load-testing platform from Dotcom-Monitor that makes realistic load testing possible without an up-front investment in hardware or software infrastructure.

This might be very different for your company, of course, but that’s a close enough approximation of a majority of customers out there. If you don’t have a device at hand, emulate mobile experience on desktop by testing on a throttled 3G network (e.g. Moto G4) on a slow 3G network, emulated at 400ms RTT and 400kbps transfer speed.

Monitoring errors on the front-end requires a bit more work because front-end performance is highly dependant on the user’s hardware, software and connection. Of course, there are also times when the problem lies not with your application but with the user’s connection or network configuration.

As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks.
