When I think about cloud-native architectures, I think about disaggregation (enabling each resource type to scale independently), fine-grained units of resource allocation (enabling rapid response to changing workload demands, i.e. elasticity), and isolation (keeping tenants apart). From shared-nothing to disaggregation. Elasticity.

A scalable architecture needs to distribute work across many threads in order to facilitate all the CPUs of a physical or virtual machine. Locking is the Achilles heel of any multi-threaded architecture. Ultimately, it leads to a state where your system won’t be able to process more data even if you add more hardware.
