Choosing Between Containers and Serverless

Choosing the right tool for the job is not always as easy as it seems. Sometimes, there is more than one tool for doing something, and such is the case for cloud-based applications. In my last “Choosing between” post, I looked out how to choose between containers and virtual machines, and here the same tension…

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…

Developing a Business Case for Containers

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,…
