This updated 2-day class (based on the prior "Architecture: The Hard Parts" class) takes a deep dive into the hard decisions architects face when creating or migrating to distributed system - hard decisions involving service granularity, data topologies, communication protocols, workflow management, and distributed transactions (to name a few).This course starts out with a deep dive exploring the differences between architectural modularity and service granularity, explaining why distributed architecture are so important in today’s world and how to get service granularity right. It then dives into defining the structure of distributed architectures, introducing the concept of an architectural quantum.
Taking a deep dive into the realm of data, we’ll explore various data topologies, and the corresponding tradeoffs associated with each. Here, you’ll learn how to align a distributed architecture with the most appropriate data topology, how to create bounded contexts, how to access data a service no longer owns, and finally various patterns for contracts and message payload.
Knowing that everything is not always microservices, this course then dives into event-driven architecture, exploring various event patterns and techniques for solving difficult problems when using asynchronous communication and event processing.
In the last part of the course, you’ll learn about the three primary decisions an architect faces when designing distributed systems—communication (async or sync), workflow (orchestration or choreography), and transactions (atomic or eventual consistency). The class concludes by bringing all three of these critical decisions together in the form of transactional sagas, simplifying the hard decisions an architect faces when designing distributed systems.
Designing distributed architectures is hard—very hard. By attending this 2-day class you’ll gain the insights and techniques to make it just a little softer.
