Mobiles have different models, screen resolutions, operating systems, network types, hardware configurations, etc. Also, how to test the hardware of the mobile phone itself, is it supporting all the software as it should? Let us have a look at the most popular types of mobile testing for applications and hardware.

A software tester’s work life includes making sure that systems that have been designed to achieve specific results behave exactly as they should. These systems are a combination of different hardware and software which have been configured to perform the desired task. An Example. What is Configuration Testing?

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. If a primary server fails, a backup server can take over and continue to serve requests.

Open source databases provide great foundations for high availability — without the pitfalls of vendor lock-in that can come with proprietary software. However, open source software doesn’t typically include built-in HA solutions. This blog provides links to such architectures — for MySQL and PostgreSQL software.

HammerDB is a software application for database benchmarking. It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The HammerDB name.

HammerDB has always used stored procedures as a design decision because the original benchmark was implemented as close as possible to the example workload in the TPC-C specification that uses stored procedures. As an example from the TPC-C specification, this is the Stock Level procedure. On MySQL, we saw a 1.5X performance advantage.

In the simplest case, you have a growing workload, and you optimize it to run more efficiently so that you don’t need to buy or rent additional hardware, so your carbon footprint stays the same, but the carbon per transaction or operation is going down.
