How should you structure your engineering team?

It’s been a few years since the “Spotify Model” became the latest trend for structuring an engineering team. But, like its predecessors, the model based on tribes and squads has some pitfalls. How to structure an engineering team is a question that’s been covered at length, from the strengths and weaknesses of common team structures to a matrix of organization based on risk and scale to why you should choose your own model.

Intro to k3s Lightweight Kubernetes Online training

Earlier this year, Rancher Labs introduced k3s, a new open source project which is a lightweight implementation of Kubernetes that is easy to install and can run on x86 and ARM infrastructure with only 512 MB of RAM required to run it. It is geared towards teams that need to deploy applications quickly and reliably to resource-constrained environments. Some use cases for k3s are edge, Single Board Computers, IoT, and CI.

Dynamic Kubernetes Informers

In the past I’ve written about how to use informers in Kubernetes for particular resources, but what if you need to be able to receive events for any Kubernetes resource dynamically? Well, there’s a client-go package for that too. At FireHydrant, we recently updated our Kubernetes integration to watch changes for any resource you configure and I wanted to write down how we made it at a high level.

Troubleshoot .NET apps with auto-correlated traces and logs

Collecting observability data like metrics, traces, and logs makes it much easier to identify bottlenecks and other performance problems in your .NET applications. When you need to troubleshoot a production incident, it’s especially important to be able to navigate all that data so you can find the source of the issue and enact a timely resolution.

Serverless Summer School (SSS) Week Four: Intro to SES with Serverless

Amazon Simple Email Service (Amazon SES) is a cloud-based email sending service designed to help digital marketers and application developers send marketing, notification, and transactional emails. This introductory course will teach you the basics of setting up a serverless SES while sharpening the skills you learned in the Wild Rydes workshop.

And Then There Were Three -- IBM, VMWare, and Rancher

When we started Rancher in 2014, our vision was to enable enterprise IT to procure and utilize computing resources (“cattle”) from any infrastructure provider. We were extremely lucky to be able to leverage wonderful technologies like Kubernetes which made computing resources consistent across all infrastructure providers.

IaaS Resilience, which cloud platform is better? Azure or AWS?

Now this blog post is only going to cover the two largest cloud providers, Microsoft’s Azure and Amazon’s AWS and only focusing on Infrastructure as a Service (Azure VMs for Azure, and EC2 for AWS) offerings they both provide, but with a bit of a deep dive in to the way they both provide resilience.

AWS Cost Optimization: Top 5 AWS Cloud Cost Mistakes

What if we told you that most organizations are making simple AWS cost optimization mistakes that lead to surprising monthly cloud bills and unnecessary overspend? As an engineer, you’d probably be relieved to know that many of your organization’s AWS spending spikes are within your team’s control, given access to the right data.

The Quest to Eradicate Lingering VPCs

Cost is a big reason many dev teams are transitioning to serverless. However, there are still some ways costs can creep up on you in serverless apps. The biggest culprit I’ve found in my own experience is the VPC resource. Because adding a VPC to a serverless stack is ridiculously easy in Stackery, I’ve sometimes gotten carried away. I’d deploy a stack with a VPC for testing, then quickly forget about it.

Authentication and Authorization for multiple Kubernetes clusters with Rancher

A Kubernetes cluster is a collection of resources running across multiple nodes. Managing these resources also entails granting and controlling users' access to them. Different teams could be running their applications on the same cluster. Configuring RBAC is essential when it comes to such multi-tenant setups. Grouping resources into namespaces and giving certain teams access to them is a good start. Rancher leverages this to more effectively group the cluster's resources into larger subsets called projects.
