2013-09-25 Wednesday - Tooling to Support Continuous Deployment

This posting is a placeholder for resources links and notes about tooling that I find interesting to support DevOps in the challenges of Configuration Management and [Continuous?] Deployment.

For some somewhat agnostic overviews of tooling and processes that can support continuous deployment  in practice...these presentations may be of interest:

While many companies have stringent regulatory constraints that require more thoughtful and methodical approaches to deployment, I thought it worth noting how implemented a RADICAL (!) DevOps culture - as an inspiring example to challenge status quo thinking of "but-that's-not-the-way-we-do-things-here..."

A Wikipedia article - providing a sparse summary/survey of some open source solutions for automated deployment tooling...

There is a great deal of fast-paced innovation in the tooling space for deployment & configuration management – here are some of the tools (slightly listed in order of what I find to be interesting and innovative)…

Microsoft System Center 2012

Less sophisticated, but perhaps a good example of how some shops can still make improvements over manual processes...even if it is just by doing things with bare-bones scripting…for example, via Rex

2013-09-17 Tuesday - ZeroMQ

Recently, while researching some distributed computing integration patterns, I happened to come across an interesting paper: Middleware Trends and Market Leaders 2011 - produced by researchers at the CERN facility in Switzerland - that cited as a leader.

Ilya Grigorik posted a nice write-up on ZeroMQ back in September 2010

2013-09-15 Sunday - Auto-Generating Documentation from DataPower Config Info?

I recently posed a question on the  IBM WebSphere DataPower SOA Appliance forum:

Auto-Generation of Documentation?

It seems that zip2html is the only option available - and it seems to be a fairly minimal / brute-force approach at that.

2013-09-15 Sunday - IBM Integration Bus

Today I'm doing some research on the relatively new IBM Integration Bus (v9.0)

IBM Integration Bus
IBM® Integration Bus formerly known as WebSphere® Message Broker is an enterprise service bus (ESB) providing connectivity and universal data transformation for service-oriented architecture (SOA) and non-SOA environments.

IBM Integration Bus introduction

What's new in IBM Integration Bus (v9.0) for WebSphere Enterprise Service Bus users?

Extended Structured Query Language(ESQL) is a programming language defined by IBM® Integration Bus to define and manipulate data within a message flow.

2013-09-03 Tuesday - Technical Debt Conjecture

Recent observations and reflections prompted me to ponder this thought:
A Technical Debt Conjecture
For a given non-trivial project,
Given [z] budgeted sprints,
for [m] developers,
Where for sufficiently large [m],
[n] items of technical debt (or defects) are introduced - as the total for all [commits | builds],
which will subsequently require [x] additional sprints to fix.

One wonders if there are lower limits for [z], [m], [n] that would allow for approximations of [x]?

One wonders what recurring ratios of m:n might occur with some predictable frequency across different organizations, and if those ratios might vary to a greater (or lesser) degree if further considered within the specific vertical context of a given industry?

One wonders if these values are the same for on-shore vs. off-shore vs. hybrid project teams?

One wonders if there is a predictable relationship between m:n and x?

One wonders how the duration [t] of a given project might affect the trend line and predictability of these factors - and if there might be clustering of values around certain frequencies of [t]?

One wonders, given the planned / budgeted value for [z] - at what sufficiently large size of [x] do most organizations kill a project?

One wonders, what ratio of z:x does a project qualify for the 'death march' designation?

One wonders what minimum ratio of m:n should be sufficient, as a monitored metric, to serve as an indicator to management that one or more of the following might apply?

  • Requirements may not be [sufficiently | clearly] defined or finalized
  • One or more developers may need to be removed from a project team
