Fight, Flight, or Freeze - Releasing Organizational Trauma Matt Stratton Failover Conf 2020

When humans are faced with a traumatic experience, our brains kick in with survival mechanisms. These mechanisms are the familiar fight or flight response, but can also include the freeze response - which occurs when we are terrified or feel that there is no chance of escape.

Y2K and Other Disappointing Disasters: Risk Reduction and Harm Mitigation  Heidi Waterhouse

Every disaster is a concatenation of smaller failures. How can we design software and processes to accept that we live in an imperfect world? Explore the concepts of resiliency, harm reduction, over-engineering, and planning for failure with real examples.

How to fail with Serverless  Jeremy Daly Failover Conf 2020

Everything fails all the time. Knowing how to deal with these failures in serverless applications becomes essential to building resilient, highly-available systems. In traditional monolithic applications, catching errors and handling retries is relatively straightforward. But as our systems become more distributed, we now have multiple (often asynchronous) components processing events from several sources, all with vastly different retry behaviors and failure mechanisms. Utilizing old patterns can cause errors to get swallowed, creating brittle, unreliable systems that are difficult to debug and hard to maintain.

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.

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.

Introduction to Service Request Automation with Cherwell

The Kelverion Runbook Suite provides a cloud automation platform with a range of automation tools including; a rich graphical design experience, smart integrations, ready built solutions and the option of an easy to configure self-service automation portal.

Managed OpenStack cheaper than self-managed?

Outsourcing OpenStack operations can significantly accelerate the OpenStack deployment process. Although most organisations are successful with the initial roll-out of the cloud, many struggle to operate it effectively post-deployment. Under certain circumstances, a fully managed OpenStack can also be a cheaper option than the self-managed one. We have recently published a webinar in which we demonstrated a detailed cost analysis of both options.

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.
