Lightbend Reactive Architecture - Professional (3-days)

Lightbend Reactive Architecture - Professional

Designing Reactive systems and microservices requires architects and teams to think differently about design - taking into account concurrency, messaging and coordination - in order to achieve the promise of resilient and elastic software. As microservices have emerged as the gold standard of developing modern software applications, every team needs to develop a deep understanding of how to design, build and operate software in a Reactive world if they want to remain relevant.

The Lightbend Reactive Architecture course teaches teams - from development managers to architects to software developers - how to think about and leverage Reactive architectures from design through to production operations.

The course presents a series of architectural exercises. Students will work in groups to address problems and design solutions. The exercises are completed without the use of code. This allows the course to appeal to a broad audience.

Benefit

• Certified Lightbend Trainers share best practices for designing Reactive microservices
• Reactive techniques and patterns

Participant

• Developers and Architects looking to develop Reactive systems
• Architects with an interest in Domain Driven Design and related architectural patterns
• Managers and Team Leads looking for elasticity, resilience and scale in their products and systems

Logistics

Level: Intermediate - practical experience in software development and analysis is assumed
Length: Three days - 21 hours of classroom time, plus breaks
Approach: Extensive design and discussion - students design a Reactive application, analyzing a sample domain, and contrasting it with a monolithic application design
Requirements: Students must bring their own laptops. Pen, paper, sticky notes and whiteboards are assets for exercise work.
