  • Cloud Is Old and New United

    This is the first post in a series on cloud conventions and innovations. Some characteristics of cloud are simply conventions—the way things are done—whereas other features are new and innovation. The difference and context for these contrasting characteristics and features is the subject of this series of posts.

    DevOps and Tools

    This is the last post in this brief two-part series on DevOps. DevOps was discussed in my previous posts on microservices so I explored it in this two-part series. In this post I survey some of the tools that align with DevOps to make it even more useful as a method to develop applications.

    DevOps: A Collection of Ideas

    This is the first post in this two-part series on DevOps. DevOps was discussed in my recent blog posts on microservices so it was natural to take some time to explore it in more detail. DevOps is formed from development and operations, two phases associated with applications—develop them then pass them to operations for support.

    Microservices and the Development Lifecycle

    This is the final post in this series on microservices. In the first post, I wrote about the design attributes of microservices, and in the second I wrote about how those characteristics aligned with cloud platform services. This post is about the lifecycle context for microservices. I use DevOps steps to organize the discussion of the lifecycle of microservices applications. DevOps is a collection of concepts, practices and tooling, as well as team organization that makes it more straightforward to get new applications and their updates deployed rapidly. Here’s a good introduction to the topic.

    High Availability in the Cloud

    This is the last post in this four-part series on high availability (HA). The focus of this post is HA in the cloud, which is challenging to discuss because the cloud is different depending on many factors. The cloud is different as it varies widely by service provider, i.e., IBM SoftLayer is significantly different from Amazon Web Services. The cloud is also different if you do it in house yourself with your own hardware and software integration or use ready-made Infrastructure as a Service like IBM PureSystems offerings designed to be up and running out of the box in as little as four hours.

    High Availability Distributed

    This is the third post in this series on high availability (HA). Initially, I set the stage for HA and last week I wrote about mainframe HA.  In this post, I discuss HA for commonly found distributed systems.

    Mainframe High Availability

    This is the second post in a series on high availability (HA) and the first to focus on a specific system, namely mainframes. Because of its long history and the deep investments made in so many areas of mainframe computing, it is challenging to write about HA. For this post, I focus on a few keystone ideas to explain it, including HA implementation in hardware and firmware and single- and multi-systems implementations.

    High Availability Concepts

    This is the first post in a series on high availability (HA). With this first post, I focus on the main ideas and concepts relating to HA. In follow-on posts, I’ll discuss HA in specific environments like mainframe, distributed and cloud.
