Rails applications consist of a database, an application server for running application code, and a web server for processing requests. Rails provides multiple integrations for its supporting database (e.g., MySQL and PostgreSQL) and web server (e.g., Apache and NGINX).

Improving DevOps Performance with DORA Metrics

Everyone in the software industry is in a race to become more agile. We all want to improve the performance of our software development lifecycle (SLDC). But how do you actually do that? If you want to improve your performance, first determine what KPI you’d like to improve. DORA metrics offer a good set of KPIs to track and improve. It started as a research by the DevOps Research and Assessment (DORA) and Google Cloud (which later acquired DORA), to understand what makes high performing teams.

How to launch Confidential VMs on Azure

Canonical is happy to announce the general availability of Ubuntu Confidential VMs (CVMs) on Microsoft Azure. Ubuntu 20.04 is the first and only Linux distribution to support Confidential VMs on Azure! Ubuntu CVMs use the latest security extensions of the third generation of AMD CPUs, Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP). As such, they bring about a fundamental shift in the traditional threat model of public clouds. They are part of the Microsoft Azure DCasv5/ECasv5 series, and only take a few clicks to enable and use!
