Convergence: Good for the Datacenter but is it Good for Apps?
Many hardware vendors have been touting convergence as the solution to the increase in total cost of ownership and long provisioning cycles found in most datacenters today. If all the servers are the same, we can save time and money deploying a homogeneous hardware footprint. This logic, however, ignores the reality that software is getting much smarter at managing tiers of storage and memory. Further, software is surely becoming more capable of being distributed but not as consistently as it needs to be for convergence to work equally well in all cases.
What is needed is a solution that embraces the tiered reality. Give software access to tiers of server infrastructure including storage-dense, balanced, compute-dense and memory-dense machines. Make it easy to map software to various hardware topologies declaratively.
