CICD Debates: Drone vs Jenkins

Introduction Jenkins has been the industry standard CI tool for years. It contains a multitude of functionalities, with almost 1,000 plugins in its ecosystem, this can be daunting to some who appreciate simplicity. Jenkins also came up in a world before containers, though it does fit nicely into the environment. This means that there is not a particular focus on the things that make containers great, though with the inclusion of Blue Ocean and pipelines, that is rapidly changing. Read More…

Using Vagrant to Emulate Rancher Environments

I spend a large amount of my time helping clients implement Rancher successfully. As Rancher is involved in just about every vertical, I come across a large number of different infrastructure configurations, including (but not limited to!) air-gapped, proxied, SSL, HA Rancher Server, and non-HA Rancher Server. Scenario & Criteria What I wanted was a way to quickly emulate an environment to allow me to more closely test or replicate an issue. Read More…

Winning Hackathons, DevOps-Style!

Recently, I moved to New York City. As a new resident, I decided to take part in the NYC DeveloperWeek hackathon, where our team won the NetApp challenge. In this post, I’ll walk through the product we put together, and share how we built a CI/CD pipeline for quick, iterative product development under tight constraints. The Problem: Have you ever lived or worked in a building where it’s a pain to configure the buzzer to forward to multiple roommates or coworkers? Read More…

Unlocking the Business Value of Docker

Why Smart Container Management is Key For anyone working in IT, the excitement around containers has been hard to miss. According to RightScale, enterprise deployments of Docker over doubled in 2016 with 29% of organizations using the software versus just 14% in 2015 [1]. Even more impressive, fully 67% of organizations surveyed are either using Docker or plan to adopt it. While many of these efforts are early stage, separate research shows that over two thirds of organizations who try Docker report that it meets or exceeds expectations [2], and the average Docker deployment quintuples in size in just nine months.

DevOps and Containers, On-Prem or in the Cloud

The cloud vs. on-premises debate is an old one. It goes back to the days when the cloud was new and people were trying to decide whether to keep workloads in on-premises datacenters or migrate to cloud hosts. But the Docker revolution has introduced a new dimension to the debate. As more and more organizations adopt containers, they are now asking themselves whether the best place to host containers is on-premises or in the cloud. Read More…

Top 5 challenges with deploying containers in production

Docker containers make app development easier. But deploying them in production can be hard. Software developers are typically focused on a single application, application stack or workload that they need to run on a specific infrastructure. In production, however, a diverse set of applications run on a variety of technology (e.g. Java, LAMP, etc.), which need to be deployed on heterogeneous infrastructure running on-premises, in the cloud or both. This gives rise to several challenges with running containerized applications in production: Read More…

Introducing Containers into Your DevOps Processes: Five Considerations

Docker has been a source of excitement and experimentation among developers since March 2013, when it was released into the world as an open source project. As the platform has become more stable and achieved increased acceptance from development teams, a conversation about when and how to move from experimentation to the introduction of containers into a continuous integration environment is inevitable. What form that conversation takes will depend on the players involved and the risk to the organization. Read More…

Containers: Making Infrastructure as Code Easier

What do Docker containers have to do with Infrastructure as Code (IaC)? In a word, everything. Let me explain. When you compare monolithic applications to microservices, there are a number of trade-offs. On the one hand, moving from a monolithic model to a microservices model allows the processing to be separated into distinct units of work. This lets developers focus on a single function at a time, and facilitates testing and scalability. Read More…

Accelerating DevOps adoption in the Nordics

Last week we announced a partnership with EVRY, one of the leading IT companies in the Nordics, to deliver Rancher’s container management platform as a service to EVRY customers. This is an exciting moment for Rancher as the service will introduce our software to a new audience looking to embrace DevOps and transform how they deliver IT. Not surprisingly, our relationship with EVRY began last year when a couple of their cloud architects downloaded Rancher and built a small test deployment. Read More…

Hidden Dependencies with Microservices

One of the great things about microservices is that they allow engineering to decouple software development from application lifecycle. Every microservice: can be written in its own language, be it Go, Java, or Python can be contained and isolated form others can be scaled horizontally across additional nodes and instances is owned by a single team, rather than being a shared responsibility among many teams communicates with other microservices through an API a message bus must support a common service level agreement to be consumed by other microservices, and conversely, to consume other microservices These are all very cool features, and most of them help to decouple various software dependencies from each other.
