Microservices – recent and upcoming events roundup

The last year or so has seen a surge in interest in microservices and so I’ve ended up contributing to a couple of podcasts on the subject and was also invited to air my thoughts by the BBC Academy after speaking at their annual internal BBC::Develop conference.  All good stuff. The links are here:

BBC Academy

Short (~15 mins) featuring myself, Russ Miles and Rachel Evans interviewed on microservices. (It’s me! On the BBC!)

Software Engineering Radio podcast #213

This is an hour long podcast from SERadio of an interview I gave last summer. It’s interesting because the longer format gives myself and Johannes time to explore some ideas in more depth than is perhaps usual.

There is a transcript of parts of the interview in the January/February 2015 issue of the IEEE software magazine. Link coming soon

.NET Rocks! #917

A little older but another hour long podcast from the awesome dudes at .NET Rocks where myself and Matt Collinge  from Compare the Market talk about organisational change, microservices and CQRS.

What’s next?

It’s looking like a really busy first half of the year (and of course I’m also working with our clients during this period too):

BCS Edinburgh – 4th February 2015, 6:30 pm

I’m speaking at the local BCS branch on microservices and the “one true way”.

Microservices Exchange, Berlin. 12/13 Feb 2015

Speaking on polyglot programmes at the microservices exchange conference in Berlin. This should be really fun and features lead thinkers in the field. Adrian Cockcroft will be there as well as former colleague Fred George (who arguable coined the term) and current colleague Sam Newman.

QCon, London. 2-6 March.

Lots happening at Qcon this year. I am a track host for the “taming microservices” track. We have Dan North, Phil Wills, Todd Montgomery and Phil Calcado (with one more to confirm) speaking on testing, design, protocols and operationalising microservices. I’m really excited about this as I really respect the speakers I’ve managed to get to talk for us. (And Todd is ex-NASA, how cool is that!).

It’s looking like a busy 6 months indeed.

QCon SF 2012 tutorial on Micro services

I have an upcoming tutorial at QCon San Francisco on Micro services. It’s scheduled for Tuesday the 6th November for the full day. The tutorial will cover evolutionary architecture, web-integration, declarative provisioning of environments and tooling that allows us to create and operationalise simple and small applications.

Promo Code: lewi100

If you want to come along, then please use my speaker code when booking; you’ll get a $100 discount on your ticket which has to be a good thing.

Micro services – evolutionary approaches for systems of systems

“Write programs that do one thing and do it well. Write programs to work together” was accepted 40 years ago yet we have spent the last decade building monolithic applications, communicating via bloated middleware and with our fingers crossed that Moore’s Law keeps helping us out. There is a better way.

Micro services. In this tutorial we will discover a consistent and reinforcing set of tools and practices rooted in the the Unix Philosophy of small and simple. Tiny applications, communicating via the web’s uniform interface with single responsibilities and installed as well behaved operating system services. So, are you sick of wading through tens of thousands of lines of code to make a simple one line change? Of all that XML? Come along and check out what the cools kids are up to (and the cooler grey beards).

In this tutorial we will cover the following topics:

Principle-driven evolutionary architecture
Capability modelling and the town planning metaphor
REST, web integration and event-driven systems of systems
Micro services, versioning, consumer driven contracts and postels law
Testing, Building and continuous delivery
Operational concerns

There will be a hands-on element to the tutorial looking at some basic tooling that allows us to very quickly create and operationalise micro-service based designs. Bring a laptop!

Agile on the Beach

I was lucky enough to be invited back to Agile on the Beach for a second year and gave a talk on Growing a culture of innovation.

The basic premise is that in todays ever more connected world, it’s becoming more and more important for companies to innovate to retain their market share but its notoriously hard to create a culture where innovation can prosper using traditional management techniques. My opinion? You can’t create culture, but you can put people, an organisational architecture and routines in place that allow a culture to grow.

My slides on the talk can be found on slideshare here and the full synopsis on the talks page. Video will be available shortly and will be added when it is.

ThoughtWorks QTB – Choose your own Programming Language

With my colleague Ian Cartwright, I recently delivered a talk on programming language adoption at ThoughtWorks EU Quarterly Technology Briefing.

The video can be found here

Synopsis

Gone are the days when your company was limited to C++ or Java. The last few years have seen an explosion of programming languages promising “10x more productivity” or a “quicker return on investment” but what is the reality behind these claims? Programming language choice has an impact far beyond the immediate, after all COBOL applications still perform billions of business critical transactions every day and an estimated 86-94%* of software cost is incurred post development. In addition, the world of computing is changing, Moore’s Law still holds, but in an unexpected way – we can no longer rely on faster CPUs to boost performance, instead we need to have multiple CPU cores. So what does this mean for language choice in the Enterprise? This Quarterly Technology Briefing will explore these dilemmas and offer practical advice on how to balance often opposing concerns; stability vs innovation; fast to market vs easy to maintain; fashion vs staff retention; etc. We’ll do this by looking at historical motivations for changing patterns of language use and ask which of those, alongside which new forces and pressures should we be considering today.

Update: Lean and Lego – Building the Millenium Falcon

Update: The talk went really well I’m pleased to say. I guess Lego and Star Wars really appeals to most geeks…
Video and slides can be found here

I’d like to say a big thank you to the organisers – a first event and an unquestionable success.

Upcoming talk: Lean and Lego – Building the Millenium Falcon
Location: Agile on the Beach – Cornwall
Dates: 15th – 16th September

I’m really pleased to be giving a talk on lean practices at the 2011 Agile on the beach conference. The talk is a slightly irreverent one, using our experiences at ThoughtWorks London of building the largest Lego set ever produced to introduce the ideas of self organisation, continuous improvement and lean practices. I’ll cover a bunch of more involved ideas from Lean too – cycle time and the like. I’m dead chuffed, as the speaker list is good and the location promises to be beautiful.

If you are interested in Agile Development or Software Engineering and live in the South West, or even want a break on the beach whilst seeing world class keynote speakers (not me) then come along – it should be fun.

Real time web – the push off

I’m participating in a bit of light-hearted fun this evening in the ThoughtWorks London office when we host a geek night with the subject of the real-time web.

There will be two “talks” – though it won’t just be powerpoint, never fear there will be demo’s too.

I’ll mainly be talking about Websockets and the stuff you need to think about when using this technology as well as demoing a performance testing tool that uses a bit of BOSH and a bit of XMPP.

It won’t just be me though, Meinhard Benn, a Strophe committer will be talking / demoing too. Personally that’s the bit I’m excited about.

Agile Brazil and ThoughtWorks, Porto Alegre

I am about to fly home this evening after spending the last week in the ThoughtWorks Brazil office and at Agile Brazil where I was speaking on agile adoption.

Agile Brazil was a great success, and I’d like to offer my thanks and congratulations to the organisers of the event. 800+ folk came to hear locals and some international speakers talk about agile software development. The ThoughtWorks booth was busy the whole time and it’s clear we have a very strong brand here.

It’s been a great trip – spending time with my Brazillian colleagues has been an absolute blast, both old-skool ThoughtWorks folk and the talented and passionate new joiners here.

Highlights include highjacking a big screen in the comp-sci department of the University so that Martin Fowler and I could watch an England game, my first experience of BBQ’d cheese, giving a talk to a room that sits 1200; and meat. So much meat.

Thanks to those that made my stay such a good experience, too many to name but Danilo, Paulo, Carlos V, Phil, Amit, Gary * 2, Greg, Caio, Camila, Pat and Sameer all made me feel very welcome. Special thanks to Verônica who made sure this gringo wasn’t completely lost when out and about in Porto Alegre.

Upcoming talk: ‘OMG! Someone broke the Internet!’ – Manchester, May 19th

I’m giving a talk on push-to-the-browser at the Manchester geek night on May the 19th. Not quite sure of the location yet – stay tuned…

WebSockets: OMG! Someone broke the internet!

So we’ve finally worked out how to build massively scalable internet applications. REST and Resource Oriented Architectures are proving hugely successful; but the Internet is changing. WebSockets are a W3C supported protocol that offer developers greater flexibility when implementing the next generation of internet applications. This flexibility doesn’t come without cost. The speaker will explore the practical applications of the WebSocket protocol, it’s limitations and the impact on internet-scale software engineering. This talk is targeted at Developers, Technical Leaders and Architects. There may even be some code.
