Since starting this blog in July of 2014, I have had an unexpected amount of growth. So much, that a lot of strain has been placed on my virtual private server (VPS). A common issue that has plagued me and many other WordPress users is the awful MySQL crash due to exhausted resources.

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. At Netflix, we've been using these technologies as they've been made available for instance types in the AWS EC2 cloud. Each dimension has progressed through these stages: 1.

Since its introduction by AWS in 2014, AWS Lambda has revolutionized the compute space and boosted the entire serverless movement. This extension was built from scratch to take into account all we’ve learned and the special requirements for monitoring ephemeral, auto-scaling, micro VMs like AWS Lambda.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. How long does it take to read the time?

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.

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. FaaS enables developers to create and run a single function in the cloud using a serverless compute model. How does function as a service work?

Two years later, I came across that same customer at the AWS re:Invent conference , who then told me they were in the midst of a big project, moving their eCommerce to AWS , targeting running a big chunk of it in Kubernetes next year. .

I've suggested adding a command to docker to make listing at least the top-level PIDs in containers easier. ## Virtual Machines The two main technologies on Linux are Xen and KVM (and there's Bhyve for BSD). What happens if processes really do try to populate all that virtual memory?
