Starting as a monolith● Easy at the beginning● Hard to scale later● Hard to detach apps● Solution?
Services● Small(er)● “Independent”● Talking to each other● Easier to deploy and scale● Is SOA the ultimate solution?
New problems● Routing traffic to the correct service● Adding and removing new instances to the pool● What if an instance dies?
A perfect solution requirements● Routing● Load balancing● Health status● Debug single node● Introspection● Safe to changes in the pool ● No single point of failure
Suboptimal solutions● DNS● Central load balancing● In App registration/discovery
Smart stack● Nerve - service registration● Synapse - service discovery
Nerve
Synapse
Benefits● Immediate discovery● Problem are detected on small intervals● Easy to debug● Introspection● Distributed infrastructure
The future● Zookeeper is still critical● Dynamic Nerve config
