Containerize a Node App in 5 Minutes

Node and Docker are a match made in heaven because the strengths of Node play to the strengths of Docker. Node microservices typically are built on top of the Express web server which can be configured with “just enough” server and run an application. Additionally, the Node package manager, NPM, makes installing and running Node…

DevOps News From Connect(); 2017

The Microsoft Connect(); 2017 online event is nearly over, and so far we’ve heard lots of exciting news from Microsoft about Azure and changes to improve their support for DevOps.  In fact, DevOps has been a big part of the theme this year. So let’s recap some of the announcements that have been made… Azure…

Using SSH with Visual Studio Team Services

In April 2016, Visual Studio Team Services introduced support for using SSH to connect to Git repositories. Over the summer of 2017, Microsoft made a number of improvements to reduce latency and improve performance for Git connections. These changes take advantage of Azure Traffic Manager to route the traffic over the Azure Global Network. According…

Why “Kubernetes vs. Swarm” is the Wrong Question

Kubernetes is getting a lot of attention these days. The container industry has coalesced around Kubernetes. And for this reason, many people are giving eulogies for Docker Swarm. While Kubernetes is incredibly popular, the dominance of Kubernetes does not imply the death of Swarm. These two systems do have overlap, but they approach a similar…

Developing a Business Case for Containers

Developing a business case for any technology is not always an easy endeavor. In many organizations, CIO’s, CTO’s, and CISO’s will see the value of adopting new technology strategies, however these are harder to sell to others in the C-suite. Those that don’t fully grasp tech see a lot of costs that they don’t understand…

Creating First-Run ARM Templates

Azure Resource Manager (ARM) templates are a great solution for creating a repeatable environment. Using Infrastructure as Code (IaC) makes  it easy to manage configurations, avoid dependency issues, and prevent server drift. Using IaC also means that you can recreate the environment as often as necessary to ensure it remains consistent. This gets complicated when…

Choosing Between Containers and Virtual Machines

Containers are simple, but harder to explain. Fundamentally, containers are a virtualization technology and they share a lot of common ground with virtual machines, however the biggest difference between the two is where the abstraction occurs. A VM hypervisor exposes a set of virtualized hardware components like a virtual network card, a virtual hard disk,…

Build, Test, and Deploy .NET Apps with Docker

I had the privilege of presenting at the Atlanta Code Camp this year on .NET and Docker. This talk covered some of the low level components that would be used to build out a DevOps pipeline for .NET apps in Docker — everything from building an app, testing and app, and pushing that app through…

Creating Recoverable TFS Backups

One of the things I’ve come to appreciate most about the cloud software-as-a-service solutions is that it can reduce work. Although there’s still a need for IT, some tasks – such as performing backups – are provided by the vendor. If you’ve ever tried to backup a Team Foundation Server by hand, you have can…

DevOps: Connecting VSTS to Azure

DevOps is about increasing efficiency and eliminating barriers. There’s a lot of convenience in deploying directly from Visual Studio Team Services into the Azure cloud. With plugin based build and release pipelines, it’s very easy to quickly configure a release and see the results online. You can quickly configure a release to deploy to Azure;…

How to Avoid a Docker Database Disaster

Containers are cool – and everyone and their mother is trying to get on board with them. While many applications are natural fit for containers in many cases, it feels like some applications are forced into containers so vendors can say, “Hey look at me! I do containers too!” This is particularly true of database…
