How to identify critical requirements for a highload system before they become a problem?

Drawing on real-world experience, this practical talk focuses on what really matters when analysing and designing highload systems.

We’ll explore how to identify non-obvious use cases, predict peak loads, and design a metrics system. I’ll walk you through how to gather non-functional requirements properly, what architectural aspects to consider from the start, and how to validate decisions made.

After the talk, you'll get a set of practices and tools for working on highload projects that will help prevent issues before they arise.

All examples are based on real projects and real mistakes — the kind you’ll want to avoid repeating.

The presentation covers all aspects of developing and documenting asynchronous APIs using the AsyncAPI specification. The focus is on the roles of systems and business analysts in these processes, methods for creating and managing specifications, and tools for working with AsyncAPI.

We will discuss how the AsyncAPI enhances the quality and efficiency of team collaboration, explore examples of code generation and automation. Special attention will be given to the interaction between analysts, developers, and testers, as well as managing changes in contracts. 

This presentation will be valuable for those who want to improve the processes of analysis, development, testing, and support of complex systems through a deep understanding of AsyncAPI.

This presentation explores the diversity of methods for developing and documenting API contracts, including OpenAPI, Excel, Protobuf, and others, with a primary focus on OpenAPI. It delves into why OpenAPI is the best tool for system analysts and clarifies the distinction between OpenAPI and Swagger. 

The presentation will demonstrate how OpenAPI contributes to enhancing the quality and efficiency of team performance. It covers practical aspects: methods for accurately describing APIs, the selection of tools for creating and maintaining specifications, and strategies for managing these processes. Focus is given to the collaboration between system analysts, developers, and testers, as well as managing changes in contracts within large projects involving teams of more than 30 people. 

It is useful for those who want through the deep understanding of OpenAPI improve the processes of analysis, development, testing, and support of complex systems.
