Generative AI is rapidly changing how we build software. With powerful language models (LLMs) and the growing availability of smaller, more accessible models (SLMs), we are entering a new phase of development where intelligent agents play a central role. Just like we once moved from procedural programming to object-oriented programming, we are now moving toward a model where software is built around interactions between AI agents. In this new approach, APIs are essential. They are how agents connect to the outside world, talk to each other, and work with existing systems. In this talk, we’ll look at how to design software based on agent interactions, with a special focus on how APIs make this possible. We’ll explore how generative models can power agents that use APIs, expose APIs, and coordinate tasks through APIs. You’ll also learn practical patterns for building systems where multiple agents collaborate effectively using clear and well-defined interfaces.

SLMs and the Agents Revolution: Rethinking How Software Is Built

Get ready for a provocative and engaging session that challenges the very notion of who, or what, can deliver a compelling presentation! In this talk, an AI agent will be built right before your eyes. Using the Google ADK framework and Gemini, this agent will scour the internet, prepare a presentation, and then deliver it. But here's where it gets really interesting: by the end of the session, you, the audience, will choose the topic the AI agent has to talk about. This raises some fascinating questions: Can the information it presents be trusted? What does this mean for the future of knowledge and communication when an AI can 'speak' with authority? Join us to find out if an AI can truly become the speaker in the room!

Perché mantenere acceso il tuo cluster quando non lo stai usando? Fai in modo che si spenga ogni notte! Con Crossplane e kube-green, puoi creare ephemeral environments che si attivano quando lavori e si spengono quando ti riposi. Immagina una configurazione che faccia il provisioning dinamico di un’infrastruttura complessa per i test, per poi spegnersi automaticamente durante le ore non lavorative come durante la notte o nei fine settimana. In questo talk, ti mostreremo come un IDP (Internal Developer Platform) può aiutare ad orchestrare in modo intelligente e on-demand la tua infrastruttura, in modo che gli sviluppatori possano concentrarsi sul creare applicazioni e non sul fare da babysitter ai cluster. Vedrai come funziona l’integrazione, esplorerai l’impatto su costi, efficienza e sostenibilità e scoprirai come passare da un infrastruttura statica a una dinamica ed eco-friendly. Risparmia denaro, riduci le emissioni e lascia riposare i tuoi cluster. Perché we will rock you, ma non per tutta la notte.

As a crucial part of a platform adoption journey, it’s essential to choose the right metrics to gain a clear, comprehensive view and drive success. While DORA metrics are valuable for platform teams, assessing platform adoption solely based on deployment frequency doesn’t make sense. Reflecting on our expertise, we’ve learned that measuring platform success involves two types of KPIs: progress metrics and outcome metrics. In this talk, we’ll explore how measuring both allows us to identify patterns and correlations between technical improvements and business success. By combining these two sets of KPIs, we gain a comprehensive view of the platform’s value. This approach helps stakeholders quantify the platform’s technical contributions while also understanding its influence on key business objectives. Ultimately, it enables us to set meaningful milestones for future improvements and effectively communicate the platform’s value across the organization.

In today’s technological landscape, the synergy between Cloud Native technologies and Artificial Intelligence (AI) opens the stage to a myriad of unexplored challenges and opportunities. Dynamic, always-on and highly scalable infrastructures, typical of the Cloud Native paradigm, seamlessly integrate with AI’s need to rapidly prototype solutions and access vast computational resources. The convergence of these two worlds has exposed some gaps in the Cloud Native ecosystem that need to be addressed. At the same time, AI opens numerous opportunities for innovation that are yet to be explored. This talk will delve into the Cloud Native Artificial Intelligence (CNAI) paradigm as a holistic approach to unlocking the full potential of the cloud in managing AI workloads and aim to anticipate the growth opportunities that lie ahead for the Cloud Native world.

Challenges and Takeaways of Managing AI Workloads on Cloud

The increasing complexity of software development presents significant risks and inefficiencies, especially for large enterprises. That’s why companies require a structured approach to streamline software delivery, with a focus on platform engineering and internal developer platforms. While existing literature often discusses platform engineering in terms of DevOps tool integration and infrastructure provisioning, its scope extends far beyond these aspects. To truly enhance service scalability and quality, platforms must prioritize data encapsulation and composability. This means addressing not just the IT infrastructure, but the entire organizational framework. Infrastructure management represents only the tip of the iceberg; to drive a successful platform engineering initiative, factors like data management and composability are equally crucial. Let’s delve into the unspoken truths of platform engineering by examining the fundamental principles necessary for a successful platform initiative.

Platform Engineering Untold Truths: Is It Just an Infrastructure Matter?

In a context where the ICT sector alone produces around the 1.4% of global CO2 emissions, adopting mindful resource usage is of paramount importance. One of the most challenging aspects about green software is understanding where to start. Before delving into more complex things, a good starting point is to raise awareness of the hidden ‘zombies’ within our infrastructure and then proceed to eliminate them. In this session, we’ll explore what green software is, its environmental and economic implications and how kube-green (an open source project listed in the CNCF landscape) immediately help us make our cloud infrastructures more sustainable.

An Open-Source First Step to Greenify Your Cloud Environments

The cloud-native landscape brings incredible advantages, but it also introduces new security challenges, making safeguarding a top priority. In the traditional policy enforcement model, manual management leaves organizations vulnerable to inevitable breaches due to human error – a matter of ‘when,’ not ‘if.’ Enter Policy-as-Code (PaC), a game-changing approach that leverages code to define and manage policies, transforming rules and conditions into actionable directives. By keeping policy definitions in source code control, whenever a change is made, it can be tested, validated, and then executed. The goal of PaC is not to detect policy violations but to prevent them. In this session we delve into the practical implementation of a Policy-as-Code strategy for your organization using Rönd and Open Policy Agent, two powerful open-source projects that could help you to redefine your security paradigm implementing an RBAC authorization mechanism over your APIs.

In rapidly expanding cloud-native ecosystem, managing distributed architectures feels like navigating stormy seas with waves of telemetry data. Yet this data can offer vital insights to sail smoothly. This session will explore strategies to avoid drowning, improving DevEx, and more. The cloud-native ecosystem has grown exponentially in the last few years, as has the complexity of the distributed architectures being built. In a context where keeping up with technology requires a substantial amount of computational power and data, monitoring our cloud-native applications has become a constant struggle against the storm. The ever-increasing volume of traces, metrics, events, and logs generated by our systems is a double-edged sword: on one hand, if not managed correctly, becoming a distraction from needed insights. On the other hand, if approached with care and thought, providing organizations the chance to sail calm cloud-native seas. In this session, we will discover how to avoid drowning in the sea of monitoring data, instead understanding how to provide insights while using only what is needed. We will explore the emerging scenarios on the horizon, abandoning the oars and testing the waters of artificial intelligence as it applies to our observability use cases. We will discuss how to leverage monitoring data, conversational DevEx, and anomaly prediction, among other topics, in this talk.
