Title

AWS re:Invent 2023 - Application Modernization, Microservices & the Strangler Fig Pattern (ENT321-R)

Summary

The session focuses on breaking large monolithic applications into microservices using AWS services.
RP and Adam discuss the business and technical drivers for adopting microservices, such as increased agility, faster innovation, and reduced total cost of ownership.
They introduce the Strangler Fig pattern for incremental refactoring and AWS Migration Hub Refactor Spaces, a service designed to facilitate this process.
Adam shares Affinity's journey, a company that leveraged AWS services to modernize their applications, reduce cognitive load on developers, and improve deployment frequency.
The session concludes with resources for further learning and an invitation to provide feedback through a survey.

Microservices Architecture: The move from monolithic to microservices architecture is driven by the need for agility, scalability, and the ability to deploy independently and frequently.
Strangler Fig Pattern: This pattern is an incremental approach to refactoring applications, which allows for the gradual replacement of parts of a monolithic application with microservices.
AWS Migration Hub Refactor Spaces: This service simplifies the setup of infrastructure for refactoring monoliths into microservices, reducing the time and effort required to start the process.
Affinity's Success Story: Affinity's experience demonstrates the practical benefits of using AWS services for modernization, including reduced developer cognitive load, increased deployment frequency, and cost savings.
Developer Productivity: Standardization, automation, and tooling are key factors in reducing cognitive load and improving developer productivity.
Feedback Loop: AWS's commitment to customer feedback is evident in the continuous improvement of their services, as seen with the inclusion of API path parameter support in Refactor Spaces based on Affinity's feedback.
Resource Links: The session provides valuable resources for attendees to explore AWS services, multi-account strategies, domain-driven design, and the Strangler Fig pattern in more detail.
