Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. It's an exciting development in cloud computing: hardware virtualization is now fast. Virtualized in Hardware**: Hardware support for virtualization, and near bare-metal speeds.

2014: Java in Flames Broken Java Stacks (2014) When I joined Netflix in 2014, I found Java's lack of frame pointer support broke all application stacks (pictured in my 2014 Surge talk on the right). I should do a blog post just on SFrames. The actual overhead depends on your workload.

It originated as Berkeley Packet Filter (BPF), an in-kernel execution engine that processes a virtual instruction set, and has been extended (aka eBPF) for providing a safe way to extend kernel functionality. I've been helping lead BPF observability since 2014, and I'm a major contributor and maintainer for the front-ends.

Since Kubernetes emerged in 2014, it has become a popular solution for scaling, managing, and automating the deployments of containerized applications in distributed environments. This virtualization makes it possible to efficiently deploy and securely run a container independently of the hosting infrastructure. What is Kubernetes?

The transaction log is split up into sections called virtual log files , commonly just called VLFs. Due to this problem, in SQL Server 2014 the algorithm changed for auto-growth of the log file.

React got popular due to the virtual document object model (DOM) which enables it to enhance performance of web apps and PWA significantly. Usage of Virtual DOM allows efficient rendering where only certain part of webpage is rerendered speeding up performance. Absence of Virtual DOM results in less memory intensive applications.

Search for recent blog posts on Linux containers, and try them out, and you'll piece together their capabilities and workings bit by bit. It's a bit early for me to say which is better nowadays on Linux, ZFS or btrfs, but my company is certainly learning the answer by running the same production workload on both.
