  DevOps has been a hot topic for many years, but it's still common for organizations to feel overwhelmed by the complexity of automating their entire infrastructure and to get hung up on which tools to use.

  It's no secret that the popularity of running containerized applications has exploded over the past several years. Being able to iterate and release an application by provisioning its dependencies through code is a big win. According to Gartner, “More than 75% of global organizations will be running containerized applications in production” by 2022.

  At Sensu Summit 2018, Sensu CEO Caleb Hailey and CTO Sean Porter sat down with Kelsey Hightower, Staff Developer Advocate at Google Cloud Platform (GCP), for a fireside chat on a variety of topics, including the evolution of the monitoring space, Kubernetes best practices, their opinions on an open core business model, how operators’ jobs are changing, and more.

  Chaos engineering + monitoring, part 1: Sensu + Gremlin

  One of my earliest jobs was as an admin for an MSP. We'd routinely generate alerts that weren't actionable, lacked context, and for most of our customers, were considered noise. From a monitoring perspective, it was bad. Customers didn't trust in the alerts they received and often resorted to having some additional monitoring product installed on their systems. It's safe to say that our auto-generated tickets and emails were largely ignored.

  At Monitorama 2018, Engineering Manager Kale Stedman shared Demonware’s journey to assisted remediation, or as he likes to call it: “How my team nearly built an auto-remediation system before we realized we never actually wanted one in the first place.”

  One of the many challenges when building an application is ensuring that it's secure. Whether you're storing hashed passwords, sanitizing user inputs, or even just constantly updating package dependencies to the latest and greatest, the effort to attain a secure application is never-ending. And even though containerization has made it easier to ship better software faster, there are still plenty of considerations to take when securing your infrastructure as well.

  Infrastructure as code: testing and monitoring

  In my last post, I talked about the evolution of infrastructure as code and its role in modern software development. To recap, let's take a quick look back at what an IaC process establishes: in a nutshell, IaC is a methodology that enables you to manage your servers and deploy your applications purely through code. Through some configuration language saved to a file, you define the resources and packages that servers need. These files can be checked into source control, and establish consistent behavior for your application across all of its environments, whether that's production, staging, or a local dev machine. A basic IaC workflow might look something like this:

  Infrastructure management has come a long way. (Mostly) gone are the days of manual configurations and deployments, when using SSH in a “for” loop was a perfectly reasonable way to execute server changes. Automation is a way of life.

  This is part 3 in a series on monitoring Kubernetes. Check out parts 1 and 2.

  In part 1 of this series, we discuss the rise of Kubernetes and Docker for containerization and container orchestration. I also shared some of the challenges these new technologies present and what sources of data we use to monitor Kubernetes. Part 2 dives into collecting Kubernetes data with Prometheus, plus the pros and cons of that approach. As promised in the conclusion of that post, I’ll address those cons — showing how Sensu and Prometheus form a complementary solution.

  Understanding RBAC in Sensu Go

  Regulating access to resources is a fundamental measure for enterprises to ensure the security and reliability of a system. The last thing you need is a stolen or weak password to give up the keys to the proverbial kingdom. With role-based access control (RBAC), this risk is mitigated by providing only the necessary access so a user in your organization doesn't have more access than needed.

  Infrastructure as code: evolution and practice

  This blog post was first published in The New Stack. 

  As infrastructure has evolved and matured over the last decade, the way in which we build and deploy that infrastructure has — for the most part — kept pace. As the velocity of deployments increased, and practices such as continuous deployment and delivery became the norm, it became critical that we manage infrastructure and deploy applications in a similar way.

  Now that we’ve officially launched Sensu Go and announced the EOL schedule for Sensu 1.x, I want to address some of the ways in which we’re either ensuring backwards compatibility between Sensu 1.x and Sensu Go or — in the case of standalone check definitions — are creating something even better.
