Architecting Containers Part 5: Building a Secure and Manageable Container Software Supply Chain

Background

In Architecting Containers Part 4: Workload Characteristics and Candidates for Containerization we investigated the level of effort necessary to containerize different types of workloads. In this article I am going to address several challenges facing organizations that are deploying containers – how to patch containers and how to determine which teams are responsible for the container images. Should they be controlled by development or operations?

In addition, we are going to take a look at

Architecting Containers Part 4: Workload Characteristics and Candidates for Containerization

Many development and operations teams are looking for guidelines to help them determine what applications can be containerized and how difficult it may be. In Architecting Containers Part 3: How the User Space Affects Your Applications we took an in depth look at how the user space affects applications for both developers and operations. In this article we are going to take a look at workload characteristics and the level of effort required to containerize different types of applications.

The goal of this article is to provide guidance based on current capabilities and best practices within

Architecting Containers Part 3: How the User Space Affects Your Application

In Architecting Containers Part 1 we explored the difference between the user space and kernel space.  In Architecting Containers Part 2 we explored why the user space matters to developers, administrators, and architects. In today’s post we will highlight a handful of important ways the choice of the user space can affect application deployment and maintenance.

While there are many ways for a given container architecture to affect and/or influence your application, the user space provides tooling that is often overlooked, namely

Architecting Containers Part 2: Why the User Space Matters

In Architecting Containers Part 1 we explored the difference between user space and kernel space. In this post, we will continue by exploring why the user space matters to developers, administrators, and architects. From a functional perspective, we will explore the connection that both ISV applications and in-house application development have to the user space.

Architecting Containers Part 1: Why Understanding User Space vs. Kernel Space Matters

Perhaps you’ve been charged with developing a container-based application infrastructure?  If so, you most likely understand the value that containers can provide to your developers, architects, and operations team. In fact, you’ve likely been reading up on containers and are excited about exploring the technology in more detail. However, before diving head-first into a discussion about the architecture and deployment of containers in a production environment, there are three important things that developers, architects, and systems administrators, need to know
