Have you ever faced a scenario where an anomaly at the backend affects the user experience at the frontend? Chances are that you’re still relying on a legacy, tightly-coupled and bulky monolith. Switching to microservices gives you a more responsive, resilient and scalable application by replacing your monolith with a decoupled architecture. And what better way to build your microservices than Lagom. This webinar will help you to leverage the power of Lagom to build your next microservice application. Lagom is an open-source framework that allows you to construct your application in Java or Scala. The agenda of the webinar - ~ Introduction to Lagom - What, When and Why? ~ Features of Lagom ~ Lagom project structure ~ Live coding demo

Our Agenda

4. Microservices vs Monolith
A monolithic application is built as a single and indivisible unit.
Places where monoliths are known to produce an issue
● Understanding the application
● Changes in application
● Scalability
● New technology barriers

5. Microservices vs Monolith
A microservices architecture breaks it down into a
collection of smaller independent units.
Benefits of Microservices over Monolithic app
● Independent components
● Easier understanding.
● Better scalability.
● Flexibility in choosing the technology

6. AY● A swedish word meaning ‘Sufficient’ or ‘Just the right amount’.
● Lagom helps us to build microservices as reactive systems so that the micro-services are
resilient, elastic and scalable from within.
● Lagom is an open source framework.
