Benefits of Micro-services • No language or technology lock-in • Easy Deployment • Updating and Scaling • No cascading failure • The ability to reuse
Breaking down the Monolith to Micro-services • No thumb rule, which works all the time • If you have complex Monolith • Not advisable to re-write from scratch • Carve out one piece at a time • Split the monolith based on business logic,
front-end and data access
• Recommended to have local database for individual service • For inter-service database access use event driven communication • If you need functionality while breaking the monolith, implement it as
micro-service
