Improve Your Scale Economies
Tip 1 – Evenly distribute heavy virtual servers across all physical servers. This will reduce over-loading of any single server as well as ensure that all servers are used to their maximum limit prior to investing in new one.
Tip 2 – Using virtual appliances for your firewalls, security screens and load balancers to decrease the carbon footprint. It’s true that hardware firewalls offer a peripheral performance improvement but when hardware and energy costs come into picture, virtual appliances offer a better cost to benefit ratio.
