[SLIDES]Jon Gyllensward @jongyllen - Crashing, monitoring and debugging in Azure
Everything was prepared. The features were in place, the critical bugs were fixed, the environments were up and running and the test were green. We were finally about to go into production with the system we had been working so hard on for the past 18 months.

We had deployed in Azure with redundancy, fail-overs and slots using continuous delivery. The customers had been doing acceptance testing for weeks. We were ready!

Then it happened.

Three days before going into production, the pipeline started halting. The applications crashed one by one. First the development environment, following the test environment. Then the staging environment and last; the production environment. No exceptions or logs pointing us in the direction of the problem.

We had three days to pin down and fix it.

This is a war-story about how we turned our Azure environments upside down, logged, debugged and at last, found the nasty bug and fixed it.

[SLIDES]Jose Carlos Chavez @jcchavezs - Distributed Tracing: understanding how all your components work together
Understanding failures or latencies in monoliths or small systems usually starts with looking at a single component in isolation. Microservices architecture invalidates this assumption because end user requests now traverse dozen of components and a single component simply does not give you enough information: each part is just one side of a bigger story.

In this talk we’ll look at distributed tracing which summarizes all sides of the story into a shared timeline and also distributed tracing tools like Zipkin, which highlights the relationship between components, from the very top of the stack to the deepest aspects of the system.

[SLIDES]Layla Porter @LaylaCodesIt - APIs Exposed!
More and more developers are building APIs, whether that be for consumption by client-side applications, exposing endpoints directly to customers so they can use an alternative front-end or wrapping up services in containers.

Now that we have all these exposed endpoints, what are we doing to secure them? Previously, our monolith was self contained with limited points of access making authentication and authorisation more straightforward - that’s no longer the case.

We’ll cover the potential risks we may face such as cross site scripting and BruteForce attacks as well as look at the possible options for securing API endpoints including OAUTH, Access Tokens, JSON web tokens, IP whitelisting, rate limiting to name but a few.

[SLIDES]Hannes Lowette @hannes_lowette - Build software like a bag of marbles, not a castle of LEGO
If you have ever played with Lego, you will know that adding, removing or changing features of a completed castle isn’t as easy as it seems. You will have to deconstruct large parts to get to where you want to be, to build it all up again afterwards. Unfortunately, our software is often built the same way. Wouldn’t it be better if our software behaved like a bag of marbles? So you can just add, remove or replace them at will?
Most of us have taken different approaches to building software: a big monolith, a collection of services, a bus architecture, etc. But whatever your large scale architecture is, at the granular level (a single service or host), you will probably still end up with tightly couple code. Adding functionality means making changes to every layer, service or component involved. It gets even harder if you want to enable or disable features for certain deployments: you’ll need to wrap code in feature flags, write custom DB migration scripts, etc. There has to be a better way!

So what if you think of functionality as loose feature assemblies? We can construct our code in such a way that adding a feature is as simple as adding the assembly to your deployment, and removing it is done by just deleting the file. We would open the door for so many scenarios!
In this talk, I will explain how to tackle the following parts of your application to achieve this goal: WebAPI, Entity Framework, Onion Architecture, IoC and database migrations. And most of all, when you would want to do this. Because… ‘it depends’.

[SLIDES]Jimmy Bogard @jbogard - Vertical Slice Architecture
Moving from a layered architecture to a vertical slice architecture can be a bit daunting. We remove abstractions, complex structures, and focus building on the axis of change, then what's next? What new structures, patterns, and policies will need to be introduced in this style of architecture? How will we deal with common business functionality, and where do concepts like CQRS and DDD fit in?

In this session, we'll introduce the idea of vertical slice architectures, and dive into the patterns, tools, and techniques used with slices. We'll also cover how you can fit vertical slices into different kinds of systems, from desktop, SPA, and normal MVC applications. Finally, we'll look at some of the new challenges that come with slices and layers, and how a different approach provides a much more maintainable end result.

[SLIDES]Sean Farmar @farmar - How can monitoring save your bacon
We usually think of monitoring as something the Operations team will take care of. In a "monolithic" system that might be enough.
But we like to distribute our systems. We deploy microservices with persistent queues and automated retries. We allow them to tolerate failure, at least for short periods of time. Sometimes it may seem everything is running OK. No heavy load, no memory or CPU surges, no immediately observable slow-downs. But in fact the system may not be functioning and effective performance is degrading. Messages are piling up in queues. Business SLA's are starting to get breached. With distributed systems, we need to do more than basic monitoring.
Let's talk about how we can do a better job at keeping the lights on and ensuring our systems are functioning as designed.
I'll introduce various aspects of monitoring and the things we need to think about when writing code. I'll show how you can optimize your distributed systems and find performance bottlenecks. You'll discover how you can win if you give monitoring a bit more love :-)

[SLIDES]Tomer Gabel @tomerg - Non-deterministic Software for the Rest of Us
Classically-trained (if you can call it that) software engineers are used to clear problem statements and clear success and acceptance criteria. Need a mobile front-end for your blog? Sure! Support instant messaging for a million concurrent users? No problem! Store and serve 50TB of JSON blobs? Presto!

Unfortunately, it turns out modern software often includes challenges that we have a hard time with: those without clear criteria for correctness, no easy way to measure performance and success is about more than green dashboards. Your blog platform better have a spam filter, your instant messaging service has to have search, and your blobs will inevitably be fed into some data scientist's crazy contraption.

In this talk I'll share my experiences of learning to deal with non-deterministic problems, what made the process easier for me and what I've learned along the way. With any luck, you'll have an easier time of it!

[SLIDES]Pedro Felix @pmhsfelix - Using Kotlin Coroutines for Asynchronous and Concurrent Programming
Asynchronous and concurrent programming play a very important role in the current world of Web APIs and microservices, where a significant part of our code is about orchestrating interactions with external systems.
Using traditional synchronous models, where threads are blocked while waiting for external responses, is not suitable for platforms where threads are costly, such as .NET or the JVM, or where there are special threads that can't be blocked, such as on Javascript or Android applications.

There are various programming models to handle asynchronicity, ranging from simple callbacks to reactive streams as a way to handle asynchronous sequences.
Among these, the concept of Future has seen broad adoption in multiple platforms (e.g. Promises/thenables in javascript, CompletableFuture in Java 8, Task in .NET), including language support via the async-await constructs, which are now available in languages such as C#, Javascript, and Python.
However, instead of also adding explicit async-await support in the Kotlin language, their designers decided to go another route and address these problems with the different and more generic concept of coroutines.

This session presents Kotlin coroutines, as implemented via suspending functions, and their use to write asynchronous and concurrent programs.
Starting from the ground-up, we show how suspending functions allows us to turn callbacks into suspension points that don't break the apparent control flow.
From then we move into creating and starting coroutines as instances of these suspending functions, taking a look at the underlying state machine and continuation interfaces.
With this knowledge, we show how the async-await construct can be implemented as library functions without needing explicit language support.
We also show how to achieve interoperability with other JVM asynchronous constructs, converting between them and coroutines.
The relation between coroutines and threads is also illustrated, with emphasis on thread scheduling (e.g. ensuring the coroutine always run in the Android UI thread) and context propagation.

With the recent release of Kotlin 1.3, coroutines graduated to a stable feature, becoming an essential language mechanism to write asynchronous code on the Kotlin language.

[SLIDES]Seth Vargo @sethvargo - So you wanna do security with microservices, eh?
Equifax, Yahoo, the NSA, IHG, Hyatt, Uber, and eBay are just a few of the over 100 companies that reported security and data privacy breaches in 2017. For many organizations, the perimeter firewall has been the only required security, but with the move to cloud, no longer can users rely on a firewall as the only means of defense. Instead, we need to adopt defense in depth and rethink the way we do security in microservices. Just like DevOps, this is a collaborative process that requires changes throughout the stack from developers, operators, security professionals, and executives.
Hackers are getting more sophisticated in their attacks. As a result, we need a strong recipe to reduce the threat of intrusion, a mechanism for detecting security breaches and anomalies, and a process for quickly responding to security incidents (“break glass”).
Seth Vargo outlines the key principles for securing microservices and distributed systems in the modern world, where applications run in cloud or hybrid cloud infrastructure. You’ll learn the challenges associated with microservices and the principles of secure applications (think 12-factor apps, but for security); you’ll also discover how to implement time-based, limited-access controls and capture security practices and policy as code.

For better and for worse, JavaScript is single-threaded by design. For over 50 years Moore’s Law has described persistent exponential growth in computational power. But recently, physical limitations have slowed the trend, with advancement now coming more frequently through the use of multiple CPUs and cores. This is fine for languages featuring threads and task-based architectures. But what about JavaScript?

Thankfully, the JavaScript community has introduced new paradigms for handling parallelism over the web. The Web Worker allows long-running code to execute in the background without blocking the UI. Starting with ES2017, Shared Memory Buffers and Atomic operations allow easier passing of data and messages among these worker processes and your main application.

[SLIDES]Yves Lorphelin @ylorph - Tamed Eventual Consistency
"In Event Sourced systems, Latency is feared by the Developpers, and Eventual Consistency is uncacceptable for Business"

Most of us have been taught that users want to see the result of actions in our systems immediately.
And that therefore a typical transactional system is a must.

And so, we stopped thinking about time.
And so, we stopped asking:
* How long are you willing to wait
* Does it make sense to show an immediate response

Event sourcing, and the associated use of CQRS (Command Query Responsibility Segregation) has put time back as a first class citizen in our systems.
And made the need of discussions about latency explicit.

Latency and Eventual consistency is not a fatality.
It is a matter of modelling.
Modelling event streams.

This talk will explore an eventsourced subsystem, build for a government HR agency.
The steps used to tame eventual consistency inside it.
As well as those taken for integrating it into the whole Legacy system.

You often hear that DDD is hard. People are trying and failing, complaining over increased complexity, which gets out of control. In fact, despite many complains that accidental complexity is overcoming the domain complexity, often this is not the case. Developers tend to over-simplify business problems and, in turn, play around with technical complexity instead. The reason for this is that many business problems are considered as "easy" or "solved" when it is actually not the case. According to past experiences, making decisions before engaging the decision-making part of the brain too often lead to underestimating of the domain complexity, poor user experience and low overall customer satisfaction.
During this talk, Alexey will show several cases like this and will try to convince you to think deeper about business problems, even if they seem to be simple at first glance.

[SLIDES]Dylan Beattie @dylanbeattie - Apps, Algorithms and Abstractions: Decoding our Digital World
It's a familiar scenario. You’re on a train, your phone goes ‘ping’, you take it out of your pocket and hey - someone sent you a message! It’s a funny cat picture. You laugh, you reply ‘LOL’, you put your phone back in your pocket… but have you ever stopped to think about what’s actually involved in making that happen? Inside even the most basic smartphone there are literally hundreds of innovations, algorithms and inventions - but how do they really work? How were they developed? And what’s the next generation of algorithms and applications going to look like?

In this talk, we’ll take a deep dive into the technology behind those everyday experiences, and demystify the algorithms and abstractions that make our digital world go round. We’ll look at everything from network addressing algorithms, frequency-hopping cellular data networks and shortest path optimisation, to wavelet compression, fingerprint recognition and media encoding schemes. Whether you’re a programmer, a product owner or just somebody who loves using the latest tech, after watching this talk you’ll never look at your phone quite the same way again.

[SLIDES]Ian Cooper @ICooper - The Clean Architecture
What is the clean architecture and how you would build one in .NET? Recently Bob Martin has categorized a set of architectures, including hexagonal architecture, onion architecture and screaming architecture as 'the clean architecture' - a layered architecture of concentric circles with a strong emphasis on separation of concerns. This architecture has become popular because of its amenability to modification as an evolutionary architecture and its support for practices such as TDD. In this presentation we will discuss the clean architecture and its benefits. More than that, in the bulk of the presentation, we will show you how to implement a clean architecture in .NET. From first steps to working code, we will show you the moves required to embrace this approach, and introduce you to some of the OSS libraries that can help you get there. All examples will be in .NET Core

Dennis Traub @dtraub - Domain Modeling in a Serverless World
Back in the day, when Eric Evans came up with Domain-Driven Design, Microservices were still in the future and nobody had ever heard of "Serverless" or Functions as a Service (FaaS).
Modeling a rich domain has always been hard, and it has become even harder with a modern architecture's share-nothing approach while multiple services and functions still need to operate on common conceptual models.
In this session, Dennis presents a few approaches to model the richness of a business domain without turning your serverless functions into a "Distributed Big Ball of Mud".

[SLIDES]Rob Ashton @RobAshton - Patterns for building zero-support distributed systems in Erlang
We have all seen the local demos of the "let it fail" philosophy that Erlang espouses, but what happens when you take that and apply it across a complete distributed system in production? What does it look like and how does it change the manner in which you then support it?

For the last several years, I have been working in a very small team, both building and deploying/supporting bespoke products that power upwards of half a million live video events a year, as well as forming the backbone of various television services across the UK. For some of our customers, it has been half a decade since we received a support call and indeed it is a virtual non-happening that anybody has to get out of bed to solve a problem in production. A lot of this results directly from our use of OTP, and there are then wider patterns that have arisen across our codebases and even the manner in which we provide support to our clients.

In this session, we will be using code and examples from real-world projects to demonstrate how we build, deploy, and then support hundreds of services/workloads across both the cloud and our on-premise high density units in production, as well as also covering how our software stack ensures that on a bad day, our services carry on delivering content even when servers are catching fire or somebody has spilled coffee on the datacentre power supply.

[SLIDES]Sirar Salih @sirarsalih - Two Tales: The time when I flew drones and when I talked to the cookie monster using Node at the Norwegian Parliament
Once upon a time I had the idea of creating a Node server to control a drone through the power of the Internet. Of course, this idea seemed crazy at the time as this was when the Internet of Things was just becoming a new buzzword. Controlling things using the Internet was a new and fascinating thing at the time. This tale (one of two) will look at how I managed to control a drone by creating and using a Node server, to fly a device from any corner of the world. This tale will dissect and investigate the node-server-ar-drone library, created by myself, at NPM.

The second tale, is a rather funny one. It takes place many years after the first tale, in an environment so bureaucratic that it leverages 8 year old technology. This second tale, is about how I sat up a Node server at the Norwegian Parliament so that I could talk to the browser's cookie monster to save and to fetch user data related to GDPR. In other words, this tale is so sensitive that it includes GDPR, the Norwegian Parliament and the all bureaucracy that follows.

Welcome to an adventurous day of tales!

You’ve finally installed Docker and typed ‘docker run hello-world’ into the terminal - congratulations! You have taken the first out of about a thousand steps to having your containerized application run in production. Let’s talk about the other nine hundred and ninety nine.

We need to look at container orchestration: who creates the containers, how many and when, who makes sure they stay up or get upgraded? We need to look at monitoring, which needs to go from looking at easily identifiable machines, to amorphous cloud applications that span multiple machines and keep moving around. We have to have get logging and debug information from our containers. We must consider security and service discovery. The list of buzzwords is long, but we’ll do our best to cover it in this talk. We will look at Docker Swarm, Kubernetes and Amazon Container Service for orchestration and discuss how to monitor, debug and secure containerized applications both on-prem and in the cloud.

[SLIDES]Mandi Walls @lnxchk - Making Security and Compliance Easy with InSpec
InSpec is an open source testing framework for infrastructure with a human- and machine-readable language for specifying compliance, security, and policy requirements.
Using a combination of command-line and remote-execution tools, InSpec can help you keep your infrastructure aligned with security and compliance guidelines on an ongoing basis, rather than waiting for and then remediating from arduous annual audits. InSpec’s flexibility makes it a key tool choice for incorporating security into a complete continuous delivery workflow, reducing the risk of new features and releases breaking established host-based security guidelines. This workshop covers the basics of working with InSpec, writing tests to reflect your organization’s security guidelines, consuming community security profiles, and managing InSpec as part of a high-velocity workflow.

[SLIDES]Roy Osherove @RoyOsherove - The Enterprise Devops Challenge
DevOps is the implementation of continuous delivery and agile concepts across the organization, focusing on pipelines as the main building blocks for delivery value internally and to the customer.
But getting to that state is complicated because it requires several facets of work: People, process and tools.
In large organizations ,we have the added complexity of :
" Multiple dependencies and sub systems
" Multiple teams, groups, business units with competing interests
" Varying degrees of agility, culture, tools, technologies and processes
" Security, compliance and policy gates

In this talk we will discuss main patterns and anti patterns for adopting and implementing DevOps pipelines throughout the organization.

James Nugent @jen20 - Infrastructure as TypeScript
For almost a decade "Infrastructure as Code" has been a DevOps buzzword - but the myriad tools in share a dirty little secret... there's no actual code! Few people like "programming" YAML or JSON (even the human-friendly variants!), and even fewer like having to reverse-engineer ways to apply known good development practices to tools which resist it at all cost.

So, what if things were different,and programming infrastructure was more like real programming, with real programming languages like TypeScript? What if you defined Lambda functions by actually writing lambdas, created abstractions using complex types, and could take advantage of existing tools for modularity, linting, refactoring and testing?

Enter Pulumi, an open-source deployment engine which enables all these things using TypeScript, Python or Go!

In this talk, we'll look at how you can write TypeScript code using Pulumi to provision traditional cloud infrastructure, manage Kubernetes and build portable "serverless" applications - all with minimal YAML in sight! We'll look at deploying to multiple regions of the same cloud, and how to build abstractions allowing multi-cloud to be a reality.

[SLIDES]Irma Spudienė & Augustas Nekrošius - Master Data API story: REST is dead, long live GraphQL?
Master data is critical information for operational and analytical decision-making within a large financial organization. In the case of SEB, Master Data includes customer, products and business arrangements information which is shared internally across our company’s systems yet externally to regulators. As part of transforming our Master Data domain we are re-designing the service interface towards our consumers. One of most popular approaches is to use REST web services for API. But what if we could have a more flexible solution when it comes to the clients’ ability to pick the data they are interested in by not having to build several consumer specific end-points? GraphQL - a very interesting REST alternative - allows the consumer of the API to specify what data it needs and limits the over-fetching or under-serving you can get with REST. During the presentation, we will explain the concepts architects and developers need to understand and talk about challenges you may face when adopting GraphQL. Furthermore, we will provide a demonstration of how REST and GraphQL coexist in our solution. Or maybe we intend to replace REST with GraphQL? Let's discuss!

"With microservices every outage is like a murder mystery" is a common complaint. But it doesn't have to be! This workshop gives an introduction on how to monitor distributed applications with open source tools and in particular the Elastic Stack (previously ELK Stack).
We dive into:
* System metrics: Keep track of network traffic and system load.
* Application logs: Collect structured logs in a central location.
* Uptime monitoring: Ping services and actively monitor their availability and response time.
* Application metrics: Get the information from the applications' metrics and health endpoints via REST or JMX.
* Request tracing: Use Sleuth to trace requests through a distributed system and Zipkin to show how long each call takes.
