A wide range of users with different operating systems, browsers, hardware configurations and other variables provides a wide sample size that helps developers discover as many issues as possible. This helps developers decide when to increase server disk space and power or whether or not using a virtual cloud server is optimal.

Traditional computing models rely on virtual or physical machines, where each instance includes a complete operating system, CPU cycles, and memory. VMware commercialized the idea of virtual machines, and cloud providers embraced the same concept with services like Amazon EC2, Google Compute, and Azure virtual machines.

Because container as a service doesn’t rely on a single code language or code stack, it’s platform agnostic. The emergence of Docker and other container services enabled companies to transport code quickly and easily. Instead, enterprises manage individual containers on virtual machines (VMs). CaaS vs. PaaS.

Firecracker is the virtual machine monitor (VMM) that powers AWS Lambda and AWS Fargate, and has been used in production at AWS since 2018. The traditional view is that there is a choice between virtualization with strong security and high overhead, and container technologies with weaker security and minimal overhead.

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.

To benchmark a database we introduce the concept of a Virtual User. For this reason we need to implement our database sessions in the form of operating system threads. So having an application client mutex lock that artificially stalls our Virtual Users does not sound good. Basic Benchmarking Concepts. The Python GIL.

Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. Traditional pointers address a memory location (often virtual of course). Cross-object pointers make this easy and natural.

Nowadays, the source code to old operating systems can also be found online. Linux is also hard coding the 1, 5, and 15 minute constants. This state is used by code paths that want to avoid interruptions by signals, which includes tasks blocked on disk I/O and some locks. Why, exactly, did Linux do this?
