Link Roundup, 9/8/14: Microservice Architecture

Microservice Architecture

Since James Lewis and Martin Fowler published their article on Microservices in March 2014, the microservices architecture pattern has been the subject of much debate in the blogosphere: Is there a good definition for it (or not), is it another form of SOA (or not), is it an answer to the monolith (or not), is it a fad or the next big thing? The following blog posts contribute to the discussion on some of these topics.

Failing at Microservices: Please avoid our mistakes!: Richard Clayton’s Unrepentant Thoughts on Software and Management recently included a blog post about his team’s attempt to implement a microservice architecture, four reasons why it failed, and some recommendations for avoiding these problems.

Microservices for the Grumpy Neckbeard: Chris Stucchio discusses what he sees as the two camps of the debate about microservices, the hipsters who see their many benefits and the neckbeards who are more suspicious, and describes an architecture that may serve to bring the two camps together.

Jørn Ølmheim and Harald Wesenberg on Teaching Architecture Metamodel-First, George Fairbanks, SATURN 2014 Presentation

By Jørn Ølmheim and Harald Wesenberg
Statoil ASA

We were fortunate enough to be able to participate at SATURN 2014. For Jørn, this was his first time at SATURN, while for Harald it was the fourth SATURN conference. As always, we knew that the quality of the conference content is high, and we were looking forward to a fun week with learning new and interesting ideas from other practitioners.

In this group of excellent presentations and tutorials there were many that stood out, but to us George Fairbanks’ talk on teaching architecture was definitely one of the greatest. Many of the more experienced participants at the conference recognized George’s experiences of trying to teach the importance of architecture to the junior team members with varying degree of success, so we were well motivated for a discussion about how this can be done better. Many of us recognize the challenges of motivation and lack of commitment both from your peers and the company to spend time on such activities.

Link Roundup, 9/2/14: DevOps: Definitions and Misconceptions

DevOps: Definitions and Misconceptions

This month, Ben Kepes at Forbes reported on ScriptRock’s efforts to raise funding from investors to expand their operations in “To Help DevOps-ify The World.” Kepes opens with an explanation of how ScriptRock must first differentiate its product and services from vendors selling “DevOps in a box.” More agile software development in less time, however, may not fit neatly in that box. Here are some links to definitions of DevOps that include components that exist outside of the box.

Defining DevOps Might Be Harder Than Defining Design: In the Under Development podcast series, Bill Higgins and Michael Coté explain DevOps, metrics, and “the processes used by designers vs. software developers vs. management consultants vs. wedding planners.” Continue reading

Link Roundup, 8/21/14: Wearable Computing

Wearable Computing

Wearable computing is coming to the masses in the forms of fitness, gaming, and medical devices while non-consumer markets such as defense and aerospace continue to push for advanced wearable technologies to enhance safety, mobility, and efficiency in places most people will never go. Here are some recent examples of the state-of-the-art technology in wearable computing and then some that, with a little tech-know-how, you can make at home:

Intel Battles Parkinson’s Disease with Big Data and Wearable Tech: Mike Wheatley at Silicon Angle describes a new project at Intel, in which a Big Data analytics platform combined with a wearable device will produce a better record of symptoms experienced by Parkinson’s patients .

The Inside Story of the Oculus Rift: Peter Rubin at Wired reports that, with the Rift, Oculus hacks the visual cortex to make a virtual-reality headset that doesn’t cause “cold sweat syndrome.”

The Cardboard Project: Google Developers show how you can build your own basic VR headset with a smartphone and some basic items that you can get at the hardware store.

Raspberry Pi GPS Helmet Cam: Martin O’Hanlon at Stuff About Code used his Raspberry Pi­-based car cam to develop a helmet cam, takes it snowboarding, and record data about speed, altitude, and temperature.

 

Link Roundup, 8/14/14: Test-Driven Development: Dead or Alive?

Test-Driven Development: Dead or Alive?

Back in the Spring, a single blog post sparked a debate that on the surface seems absurd. Is TDD actually useful and still relevant? The discourse that followed and is still following this discussion is spectacular and spans Twitter, blogs, and a series of video debates. We thank Michael Keeling of Never Let Down for bringing this debate to our attention.

TDD is dead. Long live testing.: David Heinemeier Hansson, the creator of Ruby on Rails, discusses the death of test-driven development and the need to transition from unit testing to system testing.

Is TDD Dead?: Martin Fowler engages Hansson and Kent Beck in a series of video conversations on the topic of test-driven development and its impact on software design, including confidence, test-induced design damage, and cost. Continue reading

Rey Hernandez on For Maximum Awesome, Joe Justice SATURN 2014 Keynote

by Rey Hernandez
Sony Network Entertainment International
@DeveloperRey

Many times in a project, software or otherwise, the people working on the project become so entrenched in the methods they find familiar that they allow roadblocks to get in the way of project completion. All too often those roadblocks lead to missed deadlines, cut corners, general reduction in team morale, and ultimately a product that does not meet customer expectations. In his keynote at SATURN 2014, Joe Justice of Team Wikispeed and Scrum Inc., treated us to a refreshing view of project management that illustrates how teams can be extremely productive, with high morale, and great customer satisfaction.

Link Roundup, July 29, 2014: The Cloud

The Cloud

The Future Looks “Foggy” for Cloud Computing: Greg Otto at FedScoop reports on cloudlets and cyberforaging, potential solutions for bandwidth problems at the edge of the cloud, from a talk given by the Software Engineering Institute’s Grace Lewis at the Federal Cloud Computing Summit.

Virtual Machines, JavaScript and Assembler: In a keynote presentation at the 2014 O’Reilly Velocity ConferenceScott Hanselman “explores the relationship between the cloud and the browser, many languages and one language, how it might all fit together, and what comes next.”

SMBs Tie Cloud Computing To Increased Revenue: Charles Babcock at InformationWeek reports on research by Oxford Economics and Windstream Communications that found that small and midsized businesses credit cloud computing with increasing revenues.

The Uneven Future: 2 Telling Views of Cloud Adoption: Bernard Golden at CIO gives three reasons for the uneven growth of cloud computing.

Anthony Tsakiris on Facilitating the Mini Quality Attributes Workshop, Will Chaparro and Michael Keeling, SATURN 2014 Presentation

by Anthony Tsakiris
Ford Motor Company

Architecture development activities as presented in books, articles, and classes are sometimes “heavy” – that is, they require a lot of time and people resources relative to what is available. That’s my view from an automotive embedded-control-systems environment. An argument can be made that that’s what it takes, but there’s another reality that time and resources are truly in short supply. It’s difficult to get stakeholders who are busy with multiple projects and production concerns to commit big chunks of their time to an activity like a Quality Attribute Workshop for a new project.
