API Best Practices Webinar: Metrics - What to Measure

Apigee | Google Cloud

Web APIs provide a mechanism for exposing business data and services for use by mobile devices, social networks, cloud-based systems or any other software. This presentation discusses how the state of today's APIs is roughly similar to the state of the websites of 1997, looking at how the evolution of websites can help us predict the evolution of APIs going forward. It provides a framework for thinking about the value of APIs and demonstrates how some leading API users have successfully deployed them to generate significant business value.

Why are APIs important?

Andreas Krohn

API management solutions help enterprises manage, secure, and mediate API traffic, ensure that developers and partners are productive, and grow their API programs to meet the increasing demands of a digital world. APIU management capabilities including Backend as a Service (BaaS) solutions, analytics engines, and monetization enable developers to develop and extend apps with modern features, provide deep insights into the APIs, and allow API providers to monetize their APIs and developers to share in the revenue.

APIs are a piece of technology, but they do have a business purpose and a user, or rather a developer experience which makes them either good or horrible to use and develop. Without great business-oriented APIs, there can be no API economy. In general lean architecture methods exist but are not used enough. They are useful for DevOps and Agile development, but APIs need special attention. There is a need for a “double loop” of DevOps with APIs, that’s one thing. The more important thing is to use methods which help you to treat your API as a product while covering all important business model and architecture areas. Discussions and collaboration is the key to any successful architecture. Still, many of us design our APIs and software in endless meetings or alone, using no methods at all or methods and language known only by IT professionals. The world could do with a lot of better API designs which translate into better business. These were all reasons to develop the creative-commons licensed open and lean APIOps Cycles method (www.apiopscycles.com). This talk tells the basics of the method, plus some examples of how companies have used it.

In this keynote, you'll see the difference between just APIs and API-as-a-Product, which have a significant impact on business models and value creation. Open API is the foundation of API products. The API is the interface to a value proposition. This approach leads to new business models, digital platforms, digital ecosystems. I present the API-as-a-Product stories of Swisscom and the Red Cross and show how the organization and culture has an essential impact on how technological capabilities impact the business value.

How do you back up and consistently recover your microservice architecture?

Cesare Pautasso

Microservices by definition let each service independently manage its own database. In this talk we illustrate the ultimate consequences of the Polyglot persistence principle, which can be summarized using the BAC theorem: When Backing up a microservice architecture, it is not possible to have both Consistency (after recovery) and full Availability (while backing up the system). In other words, loosely coupled Microservice architectures are doomed to become inconsistent after disaster strikes. We will present and compare several coping strategies to deal with this limitation and discuss how they impact the monolith decomposition process and the corresponding service API boundary design.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.
