Firecracker is the virtual machine monitor (VMM) that powers AWS Lambda and AWS Fargate, and has been used in production at AWS since 2018. Firecracker is open source, and there are a number of projects that make it easy to work with outside of the AWS environment too, including Weave Firekube (disclaimer: Accel is an investor in Weaveworks).

We’ll wrap it up by suggesting high availability open source solutions, and we’ll introduce you to support options for ensuring continuous high performance from your systems. Without enough infrastructure (physical or virtualized servers, networking, etc.), What does high availability mean? What is fault tolerance?

A data pipeline is a software which runs on hardware. The software is error-prone and hardware failures are inevitable. In some cases, this can be enhanced by combining data virtualization techniques with microservices architecture. A data pipeline can process data in a different order than they were received.

16% of respondents working with AI are using open source models. Many of the new open source models are much smaller and not as resource intensive but still deliver good results (especially when trained for a specific application). But 18% already have applications in production. Or is there still room for growth?

Operating System (OS) settings Swappiness Swappiness is a Linux kernel setting that influences the behavior of the Virtual Memory manager when it needs to allocate a swap, ranging from 0-100. Without further ado, let’s start with the OS settings. A setting of 100 determines it to swap aggressively to disk.

As we have seen databases are designed to handle multiple database sessions at the same time. To benchmark a database we introduce the concept of a Virtual User. We could use processes, however given we may want to create hundreds or thousands of virtual users multithreading is the best approach to implement a Virtual User.
