Deployment Patterns for API Gateways

APIs are changing the way we build applications and changing the way we expose data, both inside and outside our organizations. But what is the most efficient and effective way to deliver these APIs? That’s the job of the API gateway. In this session, we will look at different deployment patterns for API gateways, including:

  • The centralized, edge gateway
  • The multi-layer gateway
  • Microgateways, sidecars and service mesh

We discuss how the implementation and consumption of your API can (and should) influence the selection of the most appropriate API gateway pattern when it comes to production deployment.


NGINX is the world’s number one API gateway, delivering the vast majority of today’s API traffic. Learn from our experience in this space, and how to ensure that your API management platform provides the optimum deployment pattern for your APIs.


Attendees will leave the session, knowing:

  1. The different API gateway deployment patterns and their relative merits
  2. How differences between API traffic and regular web traffic influences application and API delivery infrastructure
  3. How software architecture decisions affect API delivery infrastructure

A Cell-Based Approach to Microservices Architecture

The number of microservices running in enterprises is growing almost exponentially. As a result, service composition, governance, security, and observability are becoming a challenge to implement and incorporate. A “cell-based” architecture is an emerging approach that can be applied to current or desired development and technologies to address these issues. The architecture approach helps cloud-native dev teams become more efficient, act in a more self-organized manner, and speed overall release times.


In this talk, Paul will introduce a cell-based reference architecture, which is an API-centric approach to organising both the teams and the runtimes around microservices architectures. He will explain the role of APIs in the cell-based approach, as well as examine how real applications are built as cells. Paul will explore the metrics and approaches that can be used to measure the effectiveness of the architecture and explore how organisations can implement the cell approach.

IAM Expectations: What You Ordered vs. What You Got

Imagine if you could order a black box with a button on it that says, “activate identity.” However, in real life, whatever you buy or build almost always needs some sort of customisation. In this presentation, Adam Evans, Senior Solutions Engineer at Auth0, will discuss the different perceptions of customisation and its merits for developers.   


Attendees will learn:

  • To choose the right IAM platform to avoid complex and bespoke customisation that limits delivery of future capabilities
  • Customisation “quick wins” that deliver the greatest ROI, in the shortest amount of time
  • To distinguish between “necessary” and “nice-to-have” customisations

Lost in Transaction? Consistency in Distributed Systems

You probably work on a distributed system. Even if you don't yet face a serverless microservice architecture using fancy NoSQL databases, you might simply call some remote services via REST or SOAP. This leaves you in charge of dealing with consistency yourself. ACID transactions are only available locally within components and protocols like two-phase commit don’t scale. Many projects either risk adventurous inconsistencies or write a lot of code for consistency management in the application layer. In this talk I discuss these problems and go over possible solutions, including the Saga-Pattern. I will discuss recipes and frameworks that ease the management of the right level of consistency. This allows you write business logic code. Expect fun little live hacking sessions with open source components, but also real-life stories.

Can We Shift-Left Security in a CD Pipeline?

Implementing DevOps and Continuous Delivery should speed up your software delivery. But in practice the results can be disappointing because teams still spend a lot of time on manual work that is often related to risk & security. Especially in a highly regulated world, like the Financial sector, rules and regulations can be perceived as a huge burden. 


In this talk I will discuss how this can be turned around by doing shift-left on security. Risk&Security: From burden to benefit.

Traces Are the Fuel: Making Distributed Tracing Valuable

Within our industry, it's now common knowledge that any sane microservices strategy must also account for some form of distributed tracing. However, while basic distributed traces are a good start, they are not enough to deliver true confidence about the behavior of modern production systems. In this talk, we begin with a quick refresher on the basics of distributed tracing, then show how individual distributed traces fall short of explaining critical – yet commonplace – failure modes in production. The brunt of the talk will revisit those scenarios with the benefit of various forms of aggregate trace analysis. Through these examples, we will come to understand what's possible when we go beyond individual traces to deliver more valuable insights.
