Agile Ex Meet Up – Coaching at the Organisational level

Watch Simon Copsey’s talk from the Agile Ex Meetup on “Coaching at the Organisational Level” where he explores some of the common downward spirals in IT and the larger organisation, as well as the tools that coaches and individuals can use to surface and discuss them in a way that allows for systemic change, even without formal authority.

Evolutionary challenges faced by VC funded organisations

Evolutionary challenges faced by VC funded organisations

Pioneering and pushing technology boundaries – pretty much a given nowadays for the software-driven startup. Here are some insights we’ve observed working with a number of venture capital (VC) companies who have managed to navigate the choppy waters and successfully grow their business including winning further investment along the way.

With our deep hands-on technical expertise and pragmatic focus, OpenCredo has become a natural software acceleration partner for VC funded organisations who are looking to deliver tangible value as effectively as possible. We’ve been brought in to work alongside these innovators at various stages of their journey. As such we’ve gained an appreciation for and acquired, first-hand insight into some of the pressures and challenges faced. From getting and securing that next round of funding, to grappling with the technical decisions and challenges inherent in sensibly evolving offerings to accommodate future growth and scaling.

The Power of the Architecture-driven Organisation

The Power of the Architecture-driven Organisation

As a consultant I often find myself in situations that require tricky problem solving, typically of a technical nature. Yet although it is common to approach a consultancy engagement in terms of its technical context, not all problems have a purely technical solution.

The business behind microservices: Exploring the organisational, architectural and operational challenges
The factors pushing many organisations towards Continuous Delivery with Infrastructure as Code and what’s next…

January 7, 2013 | Software Consultancy

The factors pushing many organisations towards Continuous Delivery with Infrastructure as Code and what’s next…

The practice of continuous integration in which build servers are used to build and perform testing of code is now widespread and mainstream.

While not all teams have adopted continuous integration effectively, its increasing adoption has led many to start to look for additional opportunities to improve the cost, quality and speed of delivery with which software targeted to meet business needs can be released into production environments.

Traditionally Continuous Integration addresses the question of “does the software build and pass our unit and integration test suites?”. This is often insufficient.

When Your Product Teams Should Aim to be Inefficient – Part 1

Many businesses advocate for efficiency, but this is not always the right goal. Part one of this article explores how product teams can balance two important considerations – efficiency and effectiveness. Part two builds on this idea, uncovering the non-obvious implications of using technology to bring about efficiency and wider change.

Exploring How Policy-as-Code and OPA Fit into the K8s World

November 4, 2021 | Kubernetes

Exploring How Policy-as-Code and OPA Fit into the K8s World

We always read that ‘security is everyone’s responsibility’. For any organisation, big or small, security should always be the primary concern—not a mere afterthought. In terms of Kubernetes, securing a cluster is challenging because it has so many moving parts and, apart from securing our Kubernetes environment, we also want to control what an end-user can do in our cluster.

To achieve these goals, we can start with the built-in features provided by Kubernetes like Role-Based Access Control (RBAC), Network Policies, Secrets Management, and Pod Security Policies (PSP). But we know these features are not enough. For example, we may want specific policies like ‘all pods must have specific labels’. And even if we have the policies in place, the next big question is how to enforce them on our Kubernetes cluster in an easy and repeatable manner.

In this blog post, we’ll address this challenge and other questions pertaining to OPA and how it can integrate into Kubernetes.

Machine Learning at scale: first impressions of Kubeflow

April 20, 2021 | Data Engineering, Machine Learning, Software Consultancy

Machine Learning at scale: first impressions of Kubeflow

Our recent client was a Fintech who had ambitions to build a Machine Learning platform for real-time decision making. The client had significant Kubernetes proficiency, ran on the cloud, and had a strong preference for using free, open-source software over cloud-native offerings that come with lock-in. Several components were spiked with success (feature preparation with Apache Beam and Seldon for model serving performed particularly strongly). Kubeflow was one of the next technologies on our list of spikes, showing significant promise at the research stage and seemingly a good match for our client’s priorities and skills.

That platform slipped down the client’s priority list before completing the research for Kubeflow, so I wanted to see how that project might have turned out. Would Kubeflow have made the cut?

Decision time with AWS Keyspaces

With the upcoming Cassandra 4.0 release, there is a lot to look forward to. Most excitingly, and following a refreshing realignment of the Open Source community around Cassandra, the next release promises to focus on fundamentals: stability, repair, observability, performance and scaling.

We must set this against the fact that Cassandra ranks pretty highly in the Stack Overflow most dreaded databases list and the reality that Cassandra is expensive to configure, operate and maintain. Finding people who have the prerequisite skills to do so is challenging.

It’s 2020, can I have my ML models now?

April 2, 2020 | Machine Learning

It’s 2020, can I have my ML models now?

Recent years have seen many companies consolidate all their data into a data lake/warehouse of some sort. Once it’s all consolidated, what next?

Many companies consolidate data with a field of dreams mindset – “build it and they will come”, however a comprehensive data strategy is needed if the ultimate goals of an organisation are to be realised: monetisation through Machine Learning and AI is an oft-cited goal. Unfortunately, before one rushes into the enticing world of machine learning, one should lay more mundane foundations. Indeed, in data science, estimates vary between 50% to 80% of the time taken is devoted to so-called data-wrangling. Further, Google estimates ML projects produce 5% ML code and 95% “glue code”. If this is the reality we face, what foundations are required before one can dive headlong into ML?

3 Highlights from CloudNative London 2019 (Day 2)

Continuing on from Stuart’s previous blog which covered highlights from CloudNative London conference day 1, I have put together a summary for day 2. 

Being an OCer (OpenCredo employee) has given me the opportunity to fully embed myself in the London technology scene. Alongside our direct engagements with clients, it is a chance to understand and evaluate the trends and lessons that have emerged over the past year.  

For conferences and technical content, London is a very crowded location. Every day it seems like a new conference is being announced and I know I cannot attend them all, no matter how much I want too!  Alongside some of my other colleagues, I was given the option to attend the Skillsmatter CloudNative London conference and with the increase of organisations embracing the dynamic and transformative benefits offered by an ever-growing choice of cloud providers, it seemed like a good fit.

Why Upgrading to Terraform 0.12+ Should be a Priority

Why Upgrading to Terraform 0.12+ Should be a Priority

Terraform 0.12 in recent years has emerged as the de facto standard with regards to defining and managing cloud infrastructure. It is one of four primary tools offered by HashiCorp, (Terraform, Vault, Consul and Nomad) and underpins the workflows that make up their Cloud Operating Model.

Since its first release in 2014, the wider Terraform community has embraced frequent releases and this past year has been no exception. HashiCorp announced the release of Terraform 0.12 in May 2019 and as of writing this post the official release is 0.12.9.

Here, in our little nook of the internet, we usually write about our experiences of emerging technologies, the tricky coding problems we’ve solved and how we have enhanced our clients’ businesses. We do this because we are very proud of this work. It truly matters.

Today is a little different. Today I’d like to share something a little more personal. Something that brings loneliness, kindness and technology together in an oxytocin-generating, slightly awkward embrace. Because hugs matter too.

10 Pieces of Borrowed Wisdom for Effective Tech Consultancy

My last year or so here at OpenCredo has involved a very well-supported first foray into tech consultancy. Different engagements pose both unique, as well as familiar challenges for me as a consultant, all of which played a part in shaping and moulding the way I understand and approach problems. This blog is a brief collation of wisdom that’s helped me the most during this adventure; gained by learning the hard way, as well as that acquired from mentoring and colleagues who have gone before. The shared wisdom has made me a much more effective consultant, and kept me sane in the process, for which I’m very thankful.

Microservices Anti-patterns: It’s All About the People

Quite a few of the anti-patterns we observe today on microservices projects are strongly related to how people approach the problem. Given their nature, these anti-patterns tend to be deeply ingrained and self-sustaining. Addressing them starts with increased awareness and by changing ways of approaching the problem, rather than by the introduction of yet another technical tool or framework.

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.

Versioning a Microservice System with git

Versioning a Microservice System with git

Microservice-style software architectures have many benefits: loose coupling, independent scalability, localised failures, facilitating the usage of polyglot data persistence tools or multiple programming languages.

However, they also introduce other challenges. A major one is the fact that the end-user functionality of the system will ultimately emerge as a composition of multiple services. This significantly increases the complexity of deploying the system. In addition, because we lose the concept of “versions” of the system, it becomes harder to answer questions like “what capabilities are in production?” and “when is a new feature considered ‘done’?”.

DevOps is 2016’s tech holy grail – unified development and operations, both working to deliver what the business needs, quickly, reliably, and adaptably. Done well, DevOps transforms the way organisations work; it helps break down barriers between tech teams, and between technology and the rest of the business. Good DevOps is the antidote to increasing segmentation and specialisation within companies. With the promised benefits, is it any wonder that senior managers are pushing for it in organisations spanning all sizes and industries?

Improving Flow

Improving Flow

Good consulting is, by its nature, an act of collaboration. We recently helped a company with a variety of challenges – some architecture, some coding, some systems, some people, some process (normal consultancy challenges) – unique to this client. During the project, we formalised some things we had thought before, but which had never crystallised – all the work we did was transformative. Whether it’s a code review, process review, DevOps implementation, or outright transformation, the primary goal is the same – improving flow. Flow (sometimes known as throughput) is the movement of raw materials through a system to become finished goods. It’s analogy in the service industry is the movement of customer requirements through to usable solution. And we help improve it.

The Risk of DevOps Tools: Automated Failure

The Promise of DevOps Tools

In the rush to embrace DevOps, many organisations seek out tools to help them achieve DevOps nirvana; the magical tools that will unify Development and Operations, stop the infighting, and ensure collaboration. This search for tools to solve problems exists in many domains, but seems particularly prevalent in IT (it may be real, or a reflection of my exposure to IT). The temptation to embrace new tools as a panacea is high, because the problems in IT seem so pervasive and persistent.

Shadow IT

October 30, 2015 | Cloud, DevOps

Shadow IT

In some companies, the inevitable rapidly became accepted as the way to do things, and both development and IT operations worked together to figure out how to collaborate on building systems that satisfied development’s desire for change, and operations desire for stability. Outsourcing infrastructure, and all it implied, gave rise to Devops – the unification of business needs, developer delivery, and operational capacity – but it also gave rise to something else, in companies where the operations teams weren’t quite as quick to move – Shadow IT.

Our Thoughts on DevOps and Cloud at JAX London

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).

DevOps is Transformative

DevOps is Transformative

The Pre-DevOps Environment

DevOps is transformative. This (hopefully) won’t be true forever, but it is for now. While the modern management practices of separating development and operations (and to a lesser extent, everyone else) prevail, the tearing down of the walls that separate them will remain transformative. In company after company, management and front-line staff are coming to realise that keeping functions separate, which are inherently interdependent, is a model for blame, shifted responsibility, and acrimony. It’s easy to divvy-up a company up based on function. To many people, it seems the most logical way to do it. Ops does operations, Dev does development, Marketing markets, etc. It seems much harder to do it any other way. So why do it?

The Business Behind Microservices Webinar (Video and Slides)

The Business Behind Microservices Webinar (Video and Slides)

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.

Change is coming to IT

September 21, 2015 | DevOps

Change is coming to IT

The drive for change comes from, everywhere. Within IT departments, developers are asking for more control, and want faster response times than can be provided by traditional gatekeeper IT services. Management hears about new technologies allowing more rapid deployments, better ROI, reduction in costs, increased efficiency, and increased scalability, and they want it for their customers. On top of that, systems age, technologies lose their lustre, and technical debt builds up, while it simultaneously gets harder to recruit people from a shrinking talent pool, all of which creates a case for change from within the technology itself.

Microservice Platforms: Some Assembly [Still] Required. Part One

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.

ContainerSched 2015

ContainerShed 2015Over 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!

OpenCredo’s Agile Transformation

For years, OpenCredo has been working with organisations to help them introduce new technologies, and more effective development practices, to their IT teams. This has met with a great deal of success, and we have worked with a variety of companies of various sizes. During these projects, we have consistently noticed that the changes we make reach beyond IT in their impact and effects.

Boot my (secure)->(gov) cloud

Boot my (secure)->(gov) cloud

As a company, we at OpenCredo are heavily involved in automation and devOps based work, with a keen focus on making this a seamless experience, especially in cloud based environments. We are currently working within HMRC, a UK government department to help make this a reality as part of a broader cloud broker ecosystem project. In this blog post, I look to provide some initial insight into some of the tools and techniques employed to achieve this for one particular use case namely:
With pretty much zero human intervention, bar initiating a process and providing some inputs, a development team from any location, should be able to run “something”, which, in the end, results in an isolated, secure set of fully configured VM’s being provisioned within a cloud provider (or providers) of choice.

Embracing Disruptive Innovation: OpenCredo Partners with Google

Why OpenCredo partnered with Google

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’).

Asynchronous Cloud bootstrapping with Terraform, Cloud-Init & Puppet

Asynchronous Cloud bootstrapping with Terraform, Cloud-Init & Puppet

Working with OpenCredo clients, I’ve noticed that even if you are one of the few organisations that can boast ‘Infrastructure as Code’, perhaps it’s only true of your VMs, and likely you have ‘bootstrap problems’. What I mean by this, is that you require some cloud-infrastructure to already be in place before your VM automation can go to work.

The 7 Deadly Sins of Microservices

Undeniably, there is a growing interest in microservices as we see more organisations, big and small, evaluating and implementing this emerging approach. Despite its apparent novelty, most concepts and principles underpinning microservices are not exactly new – they are simply proven and commonsense software development practices that now need to be applied holistically and at a wider scale, rather than at the scale of a single program or machine. These principles include separation of concerns, loose coupling, scalability and fault-tolerance.

Test Automation Framework – Quick start

When starting a project, teams often spend their time re-inventing the ‘automated testing wheel’.  While every project has it’s own challenges and every team it’s own needs, many things exist as common requirements of a flexible test automation framework.

This post introduces an effective Java test framework that can be used to quickly get started with test automation on a Java project.

Validating your test strategy

November 6, 2013 | Software Consultancy

Validating your test strategy

In many organisations, development and test teams have a ready answer for this, and that answer is usually wrong. Commonly, teams use test counts and code coverage statistics, which alone are not enough to validate a test approach and run the risk of giving a false sense of security to stakeholders. In practice, we are not able to fully prove the efficacy of our test strategy until after a release. Once software is in use, new defects highlight where our tests are failing to validate the software and where we need to invest effort to improve coverage. This is where many teams fail to learn and improve.

A dive into saltstack

Recently I have started looking into SaltStack as a solution that does both config management and orchestration. It is a relatively new project started in 2011, but it has a growing fanbase among Sys Admins and DevOps Engineers. In this blog post I will look into Salt as a promising alternative, and comparing it to Puppet as a way of exploring its basic set of features.
