Improving a Distributed System Post-Incident Julius Zerwick Failover Conf 2020

In this session, we will dive into a case study of how a team can recover & improve a distributed system after a major incident. Distributed systems are more prone to failure than other systems due to their incredible complexity and scale, and incidents are a fact of life with these systems.

Built-in Application Resiliency Allan Shone  Failover Conf 2020

When starting a new application build, starting with an eye on resiliency prevents headaches down the line. There are many ways to tackle this, especially within different language environments and system eco-systems, but there are many shared across them all. Getting a high-level take-away list to use as a reference later, from a dive into them during this talk, viewers will learn how to develop software that is more fault-tolerant and able to with-stand impact of failures.

Pitfalls in Measuring SLOs  Danyel Fisher & Liz Fong-Jones  Failover Conf 2020

We built support for SLOs (Service Level Objectives) against our event store so we could monitor our own complex distributed system. In the process of doing so, we learned that there were a number of important aspects that we didn’t expect from carefully reading the SRE workbook. This talk is the story of the missing pieces, unexpected pitfalls, and how we solved those problems. We’d like to share what we learned and how we iterated on our SLO adventure.

Human-in-the-Loop DevOps  Taylor Barnett  Failover Conf 2020

Within DevOps, automation has become a North Star. We want to automate the toil away, but the goal of "no toil" is unattainable. Many runbooks can only be partially automated because they still require human intervention and insights. Human-in-the-Loop DevOps is the idea that we can benefit from automating toil while still embracing the human interaction in specific tasks.

Monitor Sidekiq with Datadog

Sidekiq is a Ruby framework for background job processing. Developers can use Sidekiq to asynchronously run computationally intensive tasks—such as bulk email sending, payment processing, and data importing—to help speed up the response times of their applications. If you’re using Sidekiq Pro or Enterprise, Datadog’s integration helps you monitor the progress of your jobs and the applications that depend on them, all in a single platform.

Monitor Windows containers on Google Cloud with Datadog

Many organizations already use Docker to containerize their Windows applications and often run mixed Windows and Linux container environments to support complex architectures. With Kubernetes’s support for deploying clusters with Windows nodes, organizations can leverage the orchestration platform to easily automate container provisioning, networking, scaling, and more for their Windows applications.

How to upgrade from Ubuntu 18.04 LTS to 20.04 LTS today

Ubuntu 20.04 LTS (Focal Fossa) was officially released on April 23. This is the latest Ubuntu Long Term Support (LTS) release, with security patches and updates available until 2025. If you are currently using an older version of Ubuntu, you may be interested in upgrading. In this tutorial, we will show how to safely upgrade from Ubuntu 18.04 LTS (Bionic Beaver), the previous LTS, to the current one.

Enhanced SSH and FIDO authentication in Ubuntu 20.04 LTS

One of the most exciting security enhancements in Ubuntu 20.04 LTS (Focal Fossa) is the ability to use the Fast Identity Online (FIDO) or Universal 2nd Factor (U2F) devices with SSH. By using a second authentication factor via a device, users can add another layer of security to their infrastructure through a stronger and yet still easy to use mechanism for authentication. Ubuntu 20.04 LTS includes this feature out of the box through the latest version of OpenSSH 8.2.

Deploying Citrix Ingress Controller via the Rancher Catalog

Citrix Ingress Controller is an emerging enterprise-grade ingress controller for load balancing microservices in the Kubernetes environment. It provides advanced load balancing, rewrite/responder policy support, advanced content routing, SSL/TLS support, TCP/UDP protocol support, Canary deployment support and much more. In this article, we will discuss different deployment modes for Citrix Ingress Controller and deploy it via the Rancher catalog.
