During the day two Super Session at Citrix Synergy Barcelona, Sheng Liang, CTO of the cloud platforms group at Citrix, took the stage to discuss a number of interesting concepts. One that stood out for me was when he highlighted differences between cloud architecture and enterprise architecture. He stated that cloud architecture is different from enterprise architecture and that this fact is missed by many. At first glance this statement falls into the obvious category however like most simple concepts they only become obvious once stated and laid out in front of you.
I visit server rooms and data centres on a regular basis and it is becoming common for these to be described as company X’s cloud. However if the environment has been built using the same principles and architecture as the last data centre then the environment will never scale correctly or offer services the way a true cloud can.
Sheng Liang outlined five areas of consideration:
- Enterprise architecture scales up server clusters, cloud architecture scales out server farms
- Enterprise architecture assumes reliable infrastructure, Cloud architecture expects infrastructure to fail
- Enterprise architecture is high cost, Cloud architecture is low cost
- Enterprise architecture is IT Mgmt-centric (1:100’s), Cloud architecture is autonomic management (1:1000’s)
- Enterprise architecture uses proprietary vendor stack, cloud architecture uses open, value added stack
