Over the past decade, as operators have worked to make developers lives easier, we’ve seen an evolution in how we consume compute resources. Bare metal provided raw performance, but was inflexible. Virtual machines allowed for greater server density and high availability, but were still “clunky.” Containers, the most recent evolution, removed the overhead of a hypervisor and introduced a new level of portability that the industry had not seen before. Furthermore, containers allowed us to break down monolithic applications intro “microservices,” where each service can scale out independently, rather than scaling up an entire monolith.
