Artificial Intelligence seen from the software development lifecycle perspective

by Nerea Luis

Intelligent models often work very well in laboratory or "controlled" datasets but when it comes to testing them with big, real world, datasets we often suffer from some lack of maturity in the technical side of things: we need infrastructure, QA processes, automation pipelines, constant data ingestion, deploy evolutions of the model... to name a few

In this talk we will discuss MLOps (what it is, why we need multiple software development profiles...), where are the most common bottlenecks and some open-source initiatives to ease the "go to production" phase such as Gradio's Hugging Face, Streamlit or Kubeflow.

Getting started with Orchestration and Choreography in Distributed Applications

by Marcia Villalba

Communication between different parts of your distributed application can become very complex if you don’t have good architecture practices.

In this session, you will learn how and when to apply two architectural patterns in your distributed applications: orchestration and choreography. In addition, you will learn how to orchestrate complex workflows with state machines and how an event bus can help you choreograph micro services.

And you will also get good practices on how to use them to make your application scale and be maintainable.

DevOps Is All About Building Internal Developer Platform (IDP)

by Viktor Farcic

DevOps engineers tend to be obsessed with their favorite tools and platforms. That could be Docker, Kubernetes, Terraform, Prometheus, Grafana, Crossplane, or any other among miriad of those labeled as "DevOps".

However, that is often missing the point of what we're trying to accomplish. The goal should be to enable everyone to be in full control of their applications, including dependent services and infrastructure. DevOps is about having self-sufficient teams and the only way to accomplish that is by providing services that everyone can consume. Instead of waiting for requests to create a cluster, perform security scanning, deploy an application, and so on, ops and other specialized teams should be enabling others to do those operations.

That enablement is best accomplished by creating an Internal Developer Platform (IDP).

In this session, we'll explore the architecture and the key ingredients needed for an IDP. We'll also discuss the key benefits of an IDP and we'll see, through a demo, how we could build one.

We'll combine tools like Backstage, Argo CD, Crossplane, and quite a few others into a platform that everyone can use, no matter their experience level.

Oops. I broke the Google, now what?

by Ramón Medrano Llamas

My team and I are SREs and run one of the most important service stacks at Google: authentication. Our role is to make our services reliable and secure through engineering projects. But we sometimes fail, even if our SLO can be as high as 99.9999% uptime (31.56 seconds downtime per year) in some cases.

Whenever our services are down, mostly every Google product is down, our billions of customers can't access their own data they have entrusted us with and you make it quickly through the press. Business across the globe can be affected.

When you are oncall and get one of the pages that makes you think "oh gosh", what really happens behind the scenes? How to go from a potentially cryptic alert message to a full blown incident response team coordinating over tens of engineers?

After mitigation, the complete repair starts and the forensics style root cause analysis needs to indicate what happened and how to prevent that failure class forever. We also need to travel back in time: outages do not randomly happen, but have a trigger in a broken process, a system interaction, a small code piece.

In this talk, we'll go through the beautiful process of failure and recovery, examining real outages that have affected hundreds of millions of customers and seeing what happened, how we approached it and what we learned. We'll deep dive on some of the responses and how can the be exported to other organisations. We'll learn how our organisation has evolved to be resilient as well, over the last 15 years of operating systems at hyper-scale.

Let's dive into Terraform provider creation

by Aurélie Vache and Horacio González

Currently when we think of Infrastructure as Code (IaC), one tool seems to stand out and has become a de-facto standard: Terraform.

With Terraform you can easily build, edit and version your whole infrastructure by using Terraform builtin providers or custom ones.

But sometimes there is no provider for the infrastructure you intend to use, not even the lone no-star repository in a lost corner of the internet, only a custom REST API. What can you do? Going back to manual operations? Create your own scripts?

In this talk Horacio and Aurélie will show you, step by step, how to go from an infrastructure API to a fully functional yet light Terraform provider. By taking as base a REST API, they will explain the basics of provider creation, give some pointers on how to do a simple yet efficient provider architecture and show you the code and the provider in action.

Will they succeed in this new mission?

How to build, scale, and maintain 45 public Terraform modules with over 100 million provisions

by Anton Babenko

Copy and paste of Terraform reduce reusability, maintainability, and scalability of our configuration. In an effort not to repeat ourselves, we might start moving our configuration into modules and run into new scaling and collaboration challenges!

In this talk, I will describe some of the challenges and lessons learned in building, scaling, and maintaining the public Terraform modules for AWS components and how to apply them to your modules.

I defined an initial goal for those modules to provide a powerful and flexible way to manage infrastructure on AWS but with more than a couple thousand issues and pull-requests opened since the beginning, the goal had to change. What started as an initial set of basic Terraform AWS modules for common architectural patterns on AWS soon became a base for many customers using Terraform and required radical changes and improvements.

I will describe some of the challenges along the way and lessons learned when building entirely open-source Terraform modules used by thousands of developers. Some problems are technical such as versioning, quality assurance, documentation, compatibility promises, and upgrading. Other problems are around collaboration and software design principles, such as how to reason about feature-requests or how small should a module be. I will also examine the testing strategy for terraform-aws-modules and discuss the reasoning for not having tests!

I will provide a list of dos and don’ts for Terraform modules that highlight the critical features (e.g., documentation, feature-rich, sane defaults, examples, etc.), which make terraform-aws-modules scalable in collaboration and use.

By the end of the talk, attendees will understand proven practices around building useful, maintainable, and scalable modules, learn about public modules available to them, and how they can participate in making those open-source projects better.

Open-Source: Open Choice - A DevOps Guide for OSS Adoption

by Hila Fish

Choosing the right open-source project to use can be quite challenging - not knowing if it’s going to be the right fit, how it will behave, and if you end up wasting time trying to make it all work. We’ve all been there.

But what if I told you there’s a practical way to have a clear understanding of how to incorporate an OSS project in your environment?

In this talk, I’m going to speak about the DevOps perspective on open-source and the challenges Infra-focused engineers have with choosing the right project for their environment.

As a DevOps Engineer, I’ve seen a lot of things, stumbled upon a lot of non-based decisions, and so will present practical advice on how to choose an OSS project for your dev/prod environment and will talk about the business mindset you should have to evaluate the key indicators based on your needs and specific pain points.

The State of OpenTelemetry

by Philipp Krenn

Tracing and telemetry are popular topics right now, but the development is so quick that it also confuses:

- Starting with OpenTracing, then W3C Trace-Context, and now OpenTelemetry there are plenty of standards, but what do or don't they cover?

- With tracing being stable, how are the metric and log efforts going in OpenTelemetry?

- Where is OpenTelemetry headed as a project, and how can both users run it in combination with their vendor of choice?

This talk gives an overview of standards, projects, and how they all tie together.

Over a decade of #devops, what have we learned

by Kris Buytaert

13 years ago we had the idea to organise a conference in Gent to bridge the gap between developers and the people runing their code. It was the start of a new global movement. We never predicted that #devops would be where #devops is today. The word devops has evolved, the community has evolved.

Docker has solved all of our problems, the ones left behind were solved by Kubernetes. Everybody and their neighbour is Scrum certified now and we are all happily sipping cocktails on the beach. Or not? Why after almost 10 years of pushing culture change, teaching about Infrastructure as Code, teaching about Monitoring and Metrics … and help people to share both their pain and their learnings are most organisations still struggling with software delivery.

Over the years the word devops lost it’s meaning at least it’s original meaning. The real challenge for the next decade will be to see how we can revive those original values and ideas, if at all... Can we fix Devoops ? This talk will give you some Ideas about that.

Kubernetes at Datadog Scale

by Ara Pulido

Container technologies, although not new, have increased their popularity in the past few years, with container orchestrators allowing companies around the world to adopt these technologies to help them ship and scale microservices with precision and velocity.

Kubernetes is currently the most popular container orchestration platform nowadays, and the one chosen by Datadog to run its infrastructure. We run dozens of clusters, with thousands of nodes, and we run them on different public clouds. How are our +1K engineers able to use this infrastructure platform successfully?

Join me in this talk for our story on what we learned while we scaled our Kubernetes clusters, the contributions to Kubernetes we made along the way, how we are building a development platform around it, and how you can apply those learnings when growing your Kubernetes clusters from a handful to hundreds or thousands of nodes.

"Zero Trust DevOps" with Azure & Github Actions

by Txema González Balseiro and Manuel Sánchez Rodríguez

In this session we will address best practices to effectively implement Zero Trust architectures within our organization, this will allow us to reduce risk in all environments by establishing strong identity verification, validating device compliance before granting access and ensuring least privilege access only to explicitly authorized resources.

We will discuss how through the services Azure offers us, using Azure for Zero guardrails and blueprints to implement it and focusing primarily on identities, devices, applications, data, infrastructure and networks, helping us increase the speed with which cloud-based initiatives achieve authorization is a critical part of modernization.

The role of the Network Engineer in the DevOps era

by Christian Adell Querol

This talk will show how important it is to onboard network engineers on the DevOps culture as one of the pillars of the DevOps transformation.

Traditionally, network operations have been seen as close silos where everything moved slowly and with few (or none) visibility from the applications or systems engineering side, and it’s also true that their evolution into the DevOps principles has taken more than on the system administration, but the good news are that in 2022, most of these teams have closed the gap and are now key players on delivering IT services, adding a lot of value with them.

We can’t forget that, in a lot of cases, we sustain our applications on hybrid deployments running on complex network architectures, with multiple layers of abstraction, starting from the “real” IP network, passing over several overlays (does K8S sound familiar?) and, finally, the service mesh. Including network engineering knowledge in this endeavour will help understanding and optimising these architectures, enforcing consistent IP address management and consolidating more metrics to enrich your observability system.

In this session you will understand how to make this transformation possible and identify relevant skills and tooling that a network engineer has to adopt to jump on this boat.

Zero Trust Security

by Armon Dadgar

Zero trust security is predicated on securing everything based on trusted identities. Machine authentication and authorization, machine-to-machine access, human authentication and authorization, and human-to-machine access are the four foundational categories for identity-driven controls and zero trust security. The transition from traditional on-premises datacenters and environments to dynamic, cloud infrastructure is complex and introduces new challenges for enterprise security.

This shift requires a different approach to security, a different trust model. One that trusts nothing and authenticates and authorizes everything. Because of the highly dynamic environment, organizations talk about a "zero trust" approach to cloud security. What does “zero trust” actually mean and what’s required for you to make it successful?

Attend this session and you’ll learn from Armon Dadgar, HashiCorp founder and CTO how your organization can enable scalable, dynamic security across clouds.
