This workshop outlines the key concepts, principles, and approaches used to design and implement applications where high-performance, scalability, and resiliency are first-class quality attributes, three essential goals of many modern application architectures.

Why this workshop?

Most of these architectures are (in general) distributed and they combine different concepts and styles to achieve the highest effectiveness. It is fundamentally necessary to understand for which class of problems what architectural approaches we can leverage during the design phase and how we can implement them. The lack of a proper design leads to additional complexity, over-engineering, difficulties in extending or adding new functionalities, and potentially generates project failures.

For a better understanding, most of the concepts are exemplified using a distributed application implemented in Java, based on Spring Boot, and run inside multiple Docker containers, so that the attendees could easily relate the theory to the practice and further apply some of these tactics in their projects.

By the end of the workshop, you’ll understand:

What are the different architectural tactics, patterns, and styles to create applications focused on high-performance, scalability, and resiliency.

How to choose between (or combine) these approaches to cope with different loads and failures with minimal or no downtime.

What are the pros and cons of each approach, when should be used, and what are the consequences?

The mindset of creating modern distributed architectures.

And you’ll be able to:

Use an incremental approach to create an evolutionary architecture (i.e. architectural design) starting from the business requirements.

Complement the architectural design with a proper source code implementation (and a few architectural diagrams).

Who is it for?

software developers with hands-on experience and a taste for architectural design
technical leaders or software/solution architects
any enthusiastic with a technical background or passionate about technology
