The Language of Actors

Explore the significance and relevance of the Actor Model in modern software development through this 49-minute conference talk by Vaughn Vernon at Devoxx. Delve into the historical context of the Actor Model, its relationship with object-oriented programming, and its crucial role in addressing current and future computing challenges. Discover how actors align with Domain-Driven Design principles, facilitate the use of Ubiquitous Language in core business domains, and enable reactive scaling for concurrent systems. Learn about the advantages of actors in simplifying complex architectures, embracing asynchronous messaging, and promoting lock-free, share-nothing designs. Gain insights into implementing Domain-Driven Design with actors, including techniques like event storming and aggregate modeling. Understand the concept of Reactive Systems and how actors contribute to building resilient, responsive, and scalable software solutions.
