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.

The problem is that this system has a default libc that has been compiled without frame pointers, so any stack walking stops at the libc layer, producing a partial stack that's missing the application frames. This is pretty common and usually goes unnoticed as the flame graph looks ok at first glance. Just to name a couple of languages.

Cloud providers then manage physical hardware, virtual machines, and web server software management. The FaaS model of cloud computing debuted in 2014 with startups like hook.io. Because a third party manages part of the infrastructure, IT teams give up a measure of control over system architecture. Increased testing complexity.

Since Kubernetes emerged in 2014, it has become a popular solution for scaling, managing, and automating the deployments of containerized applications in distributed environments. Although Kubernetes simplifies application development while increasing resource utilization, it is a complex system that presents its own challenges.

Since its introduction by AWS in 2014, AWS Lambda has revolutionized the compute space and boosted the entire serverless movement. Much of what’s covered in this blog post is taken from that talk. The virtual CPU is turned off. In a future blog post, we’ll explain how to interpret Lambda metrics. Stay tuned?for

After 20 years of neck-in-neck competition, often starting from common code lineages, there just isn't that much left to wring out of the system. Consistent improvement is the name of the game, and it can still have positive impacts, particularly as users lean on the system more heavily over time. Delayed three years [8].

I wrote a blog about it years ago too, however as time has marched on, guidance has changed a bit. I always check backups first when looking at a new system. Jonathan Kehayias has written an blog post How much memory does my SQL Server actually need , with a formula that helps establish the baseline for the maximum memory value.

Web apps allow you to break the traditional constraints of the desktop and mobile operating systems and provide freedom to experiment with different varieties of software. React got popular due to the virtual document object model (DOM) which enables it to enhance performance of web apps and PWA significantly. And we can’t deny that.

On any modern operating system each process gets their own virtual memory address space so that the operating system can isolate processes and protect memory. For the 48-bit address space supported on an x64 operating system: The level-one page table can cover 256 TiB (48 bits) by pointing to 512 different level-two page tables.

In my previous blog posts, I highlighted the importance of using Event Sequence as the sort key. This was a project I created in 2014 to help Microsoft SQL Server support process incoming XEvent files, including the ability to merge XEvent files from multiple servers such as replication or high availability XEvent capture.
