Cloud-native applications have come of age. Most companies making the shift to Kubernetes are seeking productivity improvements, resource efficiency, portability, and increased scalability. The large hyperscaler cloud providers have been driving significantly better results from their hardware and software stacks by adopting open hardware architecture and open source software. But are these gains readily available to the average data center provider running cloud native workloads? And are the power and carbon footprint improvements over typical rack systems significant enough to warrant a change to open architecture? The answer to both is yes.
