The document discusses the evolution of application architecture from monolithic systems to microservices and low-code widgets, emphasizing the benefits of a service-based approach. Key points include the advantages of independent service deployment, improved user interfaces through specialized widgets, and faster time to market. Overall, it highlights how modern architectures enhance flexibility, scalability, and developer efficiency.

ARCHITECTURE TRENDS:
IN THE BEGINNING
Monolithic Applications
• Single deployment
• Tightly-coupled UI
• Any change requires complete
redeployment
Data
Business Logic
User Interface

4. 4
ARCHITECTURE TRENDS:
OLD-SCHOOL SOA
Monolith + Services
• Service layer on monolithic app
• Service = function point
• UI assembled from services
• Changes isolated via service
interface
• Some business logic may be
embedded in ESB
