Traditional applications were built as static monoliths that were deployed and managed by IT. When a new application had to be deployed, IT would create a DNS entry for the application, allocate a virtual IP (VIP) and configure that VIP on a load balancer for the application to be discovered by other clients. In the best case scenario, this process took about 4-6 weeks. Enterprises have collectively recognized the inefficiencies in this throw-over-wall deployment hand-off of the application from developers to IT operations. There were no alternatives to this model in a data center dominated by purpose-built appliances owned by IT.
