@sendilkumarn are awesome Monoliths
@sendilkumarn are simple Monoliths
@sendilkumarn are faster* Monoliths

@sendilkumarn Docker Managing the infrastructure Deciding when and how to
run the applications
@sendilkumarn Kubernetes
@sendilkumarn K8s is an open-source system
@sendilkumarn K8s is an open-source system that automates deployment containerised
applications
@sendilkumarn K8s is an open-source system that automates deployment scales

@sendilkumarn De-coupled infrastructure completely Kubernetes
@sendilkumarn • Infrastructure • Manage lifecycle • Routing
@sendilkumarn K8s makes it easy and simple
@sendilkumarn But K8s itself is not simple
@sendilkumarn How works? Kubernetes
@sendilkumarn Cluster mode
@sendilkumarn Kubernetes Master Nodes Nodes Nodes

@sendilkumarn Single Responsibility Principle Smaller YAML files Split the files
TIP
@sendilkumarn Smaller image sizes Alpine images for the win Faster

@sendilkumarn Healthy - Zombie TIP
@sendilkumarn Single process in a container… Docker don’t know which
process crashed TIP
@sendilkumarn Services - RED pattern Requests - Errors - Duration
pattern RED TIP
@sendilkumarn Resources - USE pattern Utilization - Saturation - Errors
pattern TIP
@sendilkumarn Think about Requests / Limits TIP
@sendilkumarn Clean up unused resources TIP
@sendilkumarn Monitor and tune TIP
@sendilkumarn Don’t violate DRY inside microservice. TIP
