Is Three Tiered DC Architecture Dead?
We have built data center architecture for the last two decades to serve applications with the same building blocks. Servers, Networking (LAN/SAN) and storage. Everyone will agree on that, we may not agree on what vendors to use in the data center, but that is ok.
Then the application landscape changed. Databases became bigger, everyone wants data delivered faster. Does the three tier architecture still hold up under these new requirements / constraints? You can definitely make the servers faster add more memory, make the network low latency, change the storage to flash and lower latency there too. In the end, is it worth the complexity and operational challenges you deal with? Ponder that. And while you do, consider moving to two tier approach. How? A truly converged solution built with web scale in mind. Pull a Google…
Converged architecures in the marketplace today are just new riffs on the same three tier theme. See UCS, HP Cloudsystem, etc. Then there is Nutanix. Nutanix is a truly converged. Software defined with a network connection. It is the closest you are going to come to condensing the three tier challenge you are currently dealing with.
You may not be ready for this change today, but on your next refresh cycle I guarantee you this will be a consideration. Invest wisely. The three tier architecture is not completely dead. It’s on the back nine though.
