Open Architecture for the Public Sector

In his blog Richard Veryard relates how the public sector, in the UK at least, is moving slowly towards understanding the impact of Digital Government. He reports on a workshop he attended recently to discuss some of the architectural aspects of Digital Government, hosted by Skyscape. One purpose of this discussion was to feed into the Labour Party Digital Government Review, and possibly into the Labour manifesto for the next election.

I very much agree with Richard that the key to success in this area is multi-agency collaboration that delivers joined up government. Sadly the rate of progress is evidently very slow. Richard and I responded to a UK Government call for information on Shared Services way back in 2005. See below for link. Much of what we said at that time, based on work for the Danish Government, is still highly relevant - the need to develop joined up government architecture based on business driven SOA.

Today we might add:
1. While information sharing is clearly needed between silos, an (implemented) business capability architecture would be a better way to rationalize inter-government complexities, and lay a componentized, federated foundation for collaborations. The business capability based architecture also defines units of integrity that are ideal units of provisioning or acquisition which is essential in today's Cloud based, multi-source environment.

2. In his post Richard mentioned that at the workshop there was "considerable discussion about the role of Government in providing a platform, and whether the platform should be a Minimum Viable Platform (similar to the Internet) or provide added value." The idea of an MVP is very interesting as it parallels work that we (Everware-CBDI) are doing. In our Agile Service Factory we guide organizations to develop what we now call a Common Core, which handles all the standardized services and all non-functional behaviors. We are finding this is 80 - 95% of the code/effort/cost. This Common Core becomes the enterprise (or domain or capability) platform, which is managed as one or more product lines concurrently evolving with solutions, and providing continuous change with massive reduction in cost. But the primary value is the ability to exert standardization and governance over parts of federated solutions while actively facilitating localization that does not compromise the standardized components.

3. By focusing multi-agency inter-working on capability, we have a business driven approach that is inherently service oriented, and clarity of understanding around what aspects of the common platform should be shared both within and across agency.

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...
Cloud computing is changing the way we look at IT costs, according to industry experts on a recent Cloud Luminary Fireside Chat panel discussion. Enterprise IT, traditionally viewed as a cost center, now plays a central role in the delivery of software-driven goods and services. Therefore, companies need to understand their cloud utilization and resulting costs in order to ensure profitability on their business offerings. Led by Bernard Golden, this fireside chat offers valuable insights on ho...
Microservices, for the uninitiated, are essentially the decomposition of applications into multiple services. This decomposition is often based on functional lines, with related functions being grouped together into a service. While this may sound a like SOA, it really isn't, especially given that SOA was an object-centered methodology that focused on creating services around "nouns" like customer and product. Microservices, while certainly capable of being noun-based, are just as likely to be v...
SYS-CON Events announced today the DevOps Foundation Certification Course, being held June ?, 2015, in conjunction with DevOps Summit and 16th Cloud Expo at the Javits Center in New York City, NY. This sixteen (16) hour course provides an introduction to DevOps – the cultural and professional movement that stresses communication, collaboration, integration and automation in order to improve the flow of work between software developers and IT operations professionals. Improved workflows will res...
Chef and Canonical announced a partnership to integrate and distribute Chef with Ubuntu. Canonical is integrating the Chef automation platform with Canonical's Machine-As-A-Service (MAAS), enabling users to automate the provisioning, configuration and deployment of bare metal compute resources in the data center. Canonical is packaging Chef 12 server in upcoming distributions of its Ubuntu open source operating system and will provide commercial support for Chef within its user base.
You hear the terms “subscription economy” and “subscription commerce” all the time. And with good reason. Subscription-based monetization is transforming business as we know it. But what about usage? Where’s the “consumption economy”? Turns out, it’s all around us. When most people think of usage-based billing, the example that probably comes to mind first is metered public utilities — water, gas and electric. Phone services, especially mobile, might come next. Then maybe taxis. And that’s ab...

Containers and microservices have become topics of intense interest throughout the cloud developer and enterprise IT communities. Accordingly, attendees at the upcoming 16th Cloud Expo at the Javits Center in New York June 9-11 will find fresh new content in a new track called PaaS | Containers & Microservices Containers are not being considered for the first time by the cloud community, but a current era of re-consideration has pushed them to the top of the cloud agenda. With the launch ...
An explosive combination of technology trends will be where ‘microservices’ and the IoT Internet of Things intersect, a concept we can describe by comparing it with a previous theme, the ‘X Internet.' The idea of using small self-contained application components has been popular since XML Web services began and a distributed computing future of smart fridges and kettles was imagined long back in the early Internet years.
After what feel like an interminable cycle of media frenzy followed by hype and hysteria cycles, the practical elements of real world cloud implementations are starting to become better documented. But what is really different in the cloud? How do software applications behave, live, interact and interconnect inside the cloud? Where do cloud architectures differ so markedly from their predecessors that we need to learn a new set of mechanics – and, when do we start to refer to software progra...

It's 2:15pm on a Friday, and I'm sitting in the keynote hall at PyCon 2013 fidgeting through a succession of lightning talks that have very little relevance to my life. Topics like "Python code coverage techniques" (ho-hum) and "Controlling Christmas lights with Python” (yawn - I wonder if there's anything new on Hacker News)...when Solomon Hykes takes the stage, unveils Docker, and the world shifts. If you haven't seen it yet, you should watch the video of Solomon's Pycon The Future of Linux C...
This month I want to revisit supporting infrastructure and datacenter environments. I have touched (some would say rant) upon this topic since my post in April 2014 called "Take a Holistic View of Support". My thoughts and views on this topic have not changed at all: it's critical for any organization to have a holistic, comprehensive strategy and view of how they support their IT infrastructure and datacenter environments. In fact, I believe it's even more critical today then it was a year ago ...
The 16th Cloud Expo has added coverage containers and microservices to its program for New York, to be held June 9-11 at the Jacob Javits Convention Center.

Containers are an old concept that saw renewed life with the emergence of Docker in 2013. Then late in 2014, CoreOS shook up the cloud-computing w...
