In this Ebook, you will find detailed step-by-step instructions on how to containerize your Java apps, fit them into CD pipelines, and monitor them in production. By the end of the report, you will be on your way to deploying containerized Java apps to production.
As many of you know, OpenCredo are part of the global Trifork family, and as such have access to the combined knowledge and experience of many technology and business leaders throughout the group. Getting public access to all of this expertise and technical leadership can be tricky – until now. GOTO Accelerate is a one-day business focused conference that has emerged from the very successful GOTO technology events.
Several of us from the OpenCredo team were in attendance at the inaugural EU edition of the DevOps Enterprise Summit conference. We have been big fans of the two previous US versions, and have watched the video recordings of talks (2014, 2015) with keen interest as many of our DevOps transformation clients are very much operating in the ‘enterprise’ space.
Many of our clients are currently implementing applications using a ‘microservice’-based architecture. Increasingly we are hearing from organisations that are part way through a migration to microservices, and they want our help with validating and improving their current solution. These ‘microservices checkup’ projects have revealed some interesting patterns, and because we have experience of working in a wide-range of industries (and also have ‘fresh eyes’ when looking at a project), we are often able to work alongside teams to make significant improvements and create a strategic roadmap for future improvements.
The OpenCredo team will be presenting two sessions on our recent learnings with implementing microservices at the OOP Conference, which will be running from the 1st – 5th February. We will also be running a booth, and so if you are interested in learning more about our recent projects, are keen to see if we can help you with your latest technical or organisational challenges, or want to join our team, then stop by and say hello!
Many of our clients are in the process of investigating or implementing ‘microservices’, and a popular question we often get asked is “what’s the most common mistake you see when moving towards a microservice architecture?”. We’ve seen plenty of good things with this architectural pattern, but we have also seen a few recurring issues and anti-patterns, which I’m keen to share here.
I was privileged to be invited to speak on the topic of “Defining DevOps” by the London Technology Transformation Network, alongside a long-time friend and Devoxx conference contributor Dan Hardiker. I had a great time presenting at the event, and the questions and feedback we received after the main talks was superb – I took away lots to think about, and I believe the audience did too.
It was once again a privilege to present at the annual ‘muCon 2015‘ microservices conference held in London (at the shiny new Skillsmatter CodeNode venue). Based on feedback fro talks I gave earlier in the year, I presented a completely new version of my ‘The Business Behind Microservices‘ talk, which focuses on the organisational and people side of implementing a microservice-based application.
Over the past few weeks I’ve been writing an OpenCredo blog series on the topic of “Building a Microservice Development Ecosystem”, but my JavaOne talk of the same title crept up on me before I managed to finish the remaining posts. I’m still planning to finish the full blog series, but in the meantime I thought it would be beneficial to share the video and slides associated with the talk, alongside some of my related thinking. I’ve been fortunate to work on several interesting microservice projects at OpenCredo, and we’re always keen to share our knowledge or offer advice, and so please do get in touch if we can help you or your organisation.
Having completed my marathon 3-talks-in-one-day at JavaOne on Wednesday, I’m now in a position to share all of the slides and supporting material. First up is the content associated with my “Thinking Fast and Slow with Software Development” talk. I’ve already blogged about an earlier version of this presentation on the OpenCredo blog, and so won’t go into more detail here. However, I will include the video recording (thanks to the JavaOne team for this!), the latest version of the slides, and a much requested reading list!
DevOps, Cloud and Microservices: “All Hail the Developer King/Queen”
Last week Steve Poole and I were once again back at the always informative JAX London conference talking about DevOps and the Cloud. This presentation built upon our previous DevOps talk that was presented last year, and focused on the experiences that Steve and I had encountered over the last year (the slides for our 2014 “Moving to a DevOps” mode talk can be found on SlideShare, and the video on Parleys).
Microservices, Debugging Containers and Software Development Methodologies
Once again I’m privileged to be speaking at the premier Java conference, JavaOne in San Francisco. This year I will be presenting (at least) three conferences sessions: “Building a Microservice Ecosystem”, “Debugging Java Apps in Containers” and “Thinking, Fast and Slow, with Software Development”. I say ‘at least’ three talks as I usually get press-ganged volunteered into helping out at other talks and BoF sessions, but this is simply a sign of the great community spirit and a large group of friends involved with this conference!
OpenCredo is helping Skillsmatter with the organisation of the inaugural ContainerSched conference, and we were last night in attendance at CodeNode, working our way to finalising the program alongside the Skillsmatter team. I’m pleased to say that the provisional lineup looks great (speaker acceptance emails are being sent out over the next few days), and so I wanted to share the details of some of the great content we have confirmed already.
Unless you’ve been living under a (COBOL-based) rock for the last few years, you will have no doubt heard of the emerging trend of microservices. This approach to developing ‘loosely coupled service-oriented architecture with bounded contexts’ has captured the hearts and minds of many developers. The promise of easier enforcement of good architectural and design principles, such as encapsulation and interface segregation, combined with the availability to experiment with different languages and platforms for each service, is a (developer) match made in heaven.
Over the past five years I have worked within several projects that used a ‘microservice’-based architecture, and one constant issue I have encountered is the absence of standardised patterns for local development and ‘off the shelf’ development tooling that support this. When working with monoliths we have become quite adept at streamlining the development, build, test and deploy cycles. Development tooling to help with these processes is also readily available (and often integrated with our IDEs). For example, many platforms provide ‘hot reloading’ for viewing the effects of code changes in near-real time, automated execution of tests, regular local feedback from continuous integration servers, and tooling to enable the creation of a local environment that mimics the production stack.
Microservices: Organisation, Architectural and Operational Challenges
We’re pleased to begin our series of OpenCredo webinars with “The Business Behind Microservices”, which takes a look at the some of the business and organisational challenges that come along with the decision to implement microservices.
Last week I was privileged to be able to present my “Thinking Fast and Slow with Software Development” talk at the inaugural Software Circus conference in Amsterdam. The conference was amazing, and I’ll write more about this later, but in this post I was keen to share the presentation slides and the thinking behind this talk…
The challenges of building and deploying microservices
Unless you’ve been living under a rock for the last year, you’ll undoubtedly know that microservices are the new hotness. An emerging trend that I’ve observed is that the people who are actually using microservices in production tend to be the larger well-funded companies, such as Netflix, Gilt, Yelp, Hailo etc., and each organisation has their own way of developing, building and deploying.
Over the last few years there has been exponential growth in the interest of containers and schedulers – technology such as Docker, rkt, Mesos, and Kubernetes are now commonplace within the IT domain, and with the rise of microservices, these technologies are set to become even more popular. Skillsmatter are keen to drive forward the discussions and knowledge sharing within this area of technology, and have created a conference focused exclusively on containers and schedulers: ContainerSched!
Learning about the benefits of Kubernetes from the Kismatic Team
As part of my writing for InfoQ, I recently had the pleasure of sitting down and chatting with Joseph Jacks and Patrick Reilly from Kismatic Inc, a company offering enterprise Kubernetes support, and asked about their thoughts on the recent Kubernetes v1.0 launch, the history of the project, and how this container orchestration platform may impact the future of microservice deployment.
Recently OpenCredo chose to partner with Google in order to share knowledge and resources around the Google Cloud Platform offerings. Our clients come in many shapes and sizes, but typically all of them realise three disruptive truths of the modern IT industry: the (economic) value of cloud; the competitive advantage of continuous delivery; and the potential of hypothesis and data-driven product development to increase innovation (as popularised by the Lean Startup / Lean Enterprise motto of ‘build, measure, learn’).
