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.

Chef automation for infrastructure management

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. Configuration management tools like Chef, Puppet, and Ansible — once on the bleeding edge — are now used by most enterprises.

Monitoring Kubernetes + Docker, part 3: Sensu + Prometheus

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

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.

How to monitor 1,000 network devices using Sensu Go and Ansible (in under 10 minutes)

Network monitoring at scale is an age-old problem in IT. In this post, I’ll discuss a brief history of network monitoring tools — including the pain points of legacy technology when it came to monitoring thousands of devices — and share my modern-day solution using Sensu Go and Ansible.

Filters: valves for the Sensu monitoring event pipeline

Filters, the mechanism for allowing and denying events to be handled, have been given a refresh in Sensu Go. These new and improved JavaScript filters give you a way to express business logic through filtering, giving you more awareness of your environment, reducing alert fatigue, and improving performance. In this post, I’ll share what’s new with filters, using examples in Sensu Go. (If you haven’t already, you can download it here.)
