@sendilkumarn Independent Development

@sendilkumarn Independent Deployment

@sendilkumarn Fault Isolation

@sendilkumarn Granular Scaling

@sendilkumarn Wow, this is awesome I just need to create
the micro services. It solves all my problems

@sendilkumarn Wow, it is awesome I just need to create

@sendilkumarn Monoliths are pe`ect ]t for most of the use-cases.

@sendilkumarn Think a lot before embarking a journey ✈into micro-services.

@sendilkumarn StaS faster with monolith. Then understand your domain and
then conveS them to micro-services

@sendilkumarn Side-eaects of Microservices

@sendilkumarn 99.999999999999% availability is always expected

@sendilkumarn Service Registries / Health checkers

@sendilkumarn ❌ ❌ ❌ ❌ ❌ ❌ ❌

@sendilkumarn Microservices in JHipster

@sendilkumarn API Gateway BFF pa.ern

@sendilkumarn Let us create a microservice application

@sendilkumarn Kubernetes

@sendilkumarn Kubernetes is Open -source system for automating deployment, scaling
and management of containerized applications

@sendilkumarn With JHipster you can create Kubernetes con]guration ]les that
eases your Kubernetes con]guration.
