News

Databases have limits that if you build a popular service and run it for a long time you’ll undoubtedly hit and need to plan for. This post talks about one such case, migrating a single table with 70 billion records and growing at more than 100 million rows a week.

I wrote a post this week for SecAdvent, an introduction to the topic of software bill of materials, applicable use cases and in particular looking at the CrystalDX set of specifications and tools.

Lots of teams have small home-grown monitoring services that sometimes see less testing and automation than the services they monitor. Sometimes changes to those services can lead to unexpected downside like with this interesting incident report.

Large organisations are rapidly changing how they work, adopting lots of devops practices and better integrating previously separate business units. This post summarises some of that towards a new operating model.

Terraform, or other infrastructure as code tools, provide a programming language. But how often do we apply patterns and practices learned from other programming languages? This post takes us through a nice refactoring exercise to make the point.

Another post on applying structure and patterns to Terraform. This post looks at the roles and profiles pattern which evolved from the Puppet community and applying it to Terraform and Terragrunt.

How do we relate conversations about digital transformation at the business level to devops practices and to agile software development? This post takes a run at providing an answer, and discusses why this is relevant to leaders at different levels of an organisation.

Access control systems can be complex, and Kubernetes RBAC is no exception. This post covers some behind-the-scenes details as well as pitfalls to avoid.

Lots of organisations deploy to Linux but develop on other platforms. Sometimes it’s useful to have a local linux VM. This post covers how one open source project has been adopting multipass.

Tools

Bicep is a new and experimental declarative language which compiles down to Azure Resource Manager (ARM) templates.

Localizer is a no-frills development tool for Kubernetes that aims to let you mainly ignore Kubernetes, instead proxying services so they appear as local services on the host.

A handy small utility for any AWS admin. Provide an AWS IP address and digaws will return details like region, AWS service and more.
