Survivorship Bias in Observability

During World War II, a mathematician named Abraham Wald worked on a problem – identifying where to add armor to planes based on the aircraft that returned from missions and their bullet puncture patterns. The obvious and accepted thought was that the bullets represented the problem areas for the planes. Wald pointed out that the problem areas weren’t actually these areas, because these planes survived.

SQL Server, Part 4: Understanding built-in SQL Server principals

In the previous blog in this series, we discussed the principle of least privilege, and the importance of assigning bare minimum privileges to users and systems at database or server levels. However, there are certain built-in principals in your database that possess all permissions in SQL Server. If an attacker managed to get hold of one of these principals, the database could be easily exploited and damaged.

Best practices for creating end-to-end tests

Browser (or UI) tests are a key part of end-to-end (E2E) testing. They are critical for monitoring key application workflows—such as creating a new account or adding items to a cart—and ensuring that customers using your application don’t run into broken functionalities. But browser tests can be difficult to create and maintain. They take time to implement, and configurations for executing tests become more complex as your infrastructure grows.

Unlock the flexibility and financial benefits of Azure VMs with Site24x7

Virtual machines (VMs) are one of the on-demand, scalable computing resources that Microsoft Azure offers. They enable streamlined allocation of resources in backup, disaster recovery, and deployment environments. A VM is typically chosen when you need more control over your computing environment. However, Azure VMs come with the challenge of simultaneously monitoring them across multiple environments when the VMs are spread unevenly, with some being overutilized and others underutilized.

Qovery and the Twelve-Factor App methodology

The Twelve-Factor App methodology is a methodology for building platform-agnostic and resilient applications. It was introduced by Adam Wiggins while working at Heroku in 2011. Nearly 10 years later, this methodology is still considered by the developer community as an excellent practice to follow when building an application. In this article, we will see step by step how Qovery respects and improves the 12-factor methodology. Here we go.

KMC - Hands On with K3s Support in Rancher 2.4 - 2020-06-16

K3s, the lightweight- certified Kubernetes distribution created by Rancher Labs, has become a popular choise for IoT and edge computing. But Rancher users have been asking for tighter integration between Rancher Server and K3s. With Rancher 2.4, new Rancher HA installations can be installed on K3s clusters with external SQL databases. This setup simplifies cluster administration with no need to operate etcd. Management of the database can be offloaded to hosted solutions like RDS running MySQL. In this Kubernetes Master Class, Rancher Software Engineers will discuss and demo the new K3s support in Rancher, review use cases and best practices.

Longhorn Launch Webinar - ANZS - 2020-06-16

This is the recording of the virtual launch event for the GA launch of the CNCF project Longhorn. When combined with Rancher, Longhorn provides DevOps teams with a lightweight, reliable cloud-native management and storage orchestration platform for any Kubernetes environment. Originally created by Rancher as an open source project in 2017, Longhorn was donated to the CNCF in 2019 as a sandbox project. On May 28, Longhorn will reach ‘General Availability’ status, providing the cloud-native ecosystem with lightweight and reliable persistent storage solution for Kubernetes.
