We looked at a couple of papers that had pre-prints available last week, today we’ll be looking at one of the most anticipated papers of this year’s crop: Amazon’s Firecracker. Firecracker is the virtual machine monitor (VMM) that powers AWS Lambda and AWS Fargate, and has been used in production at AWS since 2018.

When it comes to access to their applications, users demand instant, reliable, and secure interactions — and that means databases must be highly available. With database high availability (HA), services are largely uninterrupted, and end users are largely satisfied. The obvious answer is this: To achieve high availability.

With the average cost of unplanned downtime running from $300,000 to $500,000 per hour , businesses are increasingly using high availability (HA) technologies to maximize application uptime. Where a high availability design once worked well, it can no longer keep up with more complex requirements. there cannot be high availability.

A scalable architecture needs to distribute work across many threads in order to facilitate all the CPUs of a physical or virtual machine. Ultimately, it leads to a state where your system won’t be able to process more data even if you add more hardware. Now let’s see how this works for the two use cases mentioned earlier.
