The previous post was on Events as a measurement of Cloud Database performance. Today we focus on the pricing of the cloud database. 

It may be true that the cost of running a cloud database for high volume load may be significantly cheaper rather than the cost of running the same database and connections on-premise. This comes from the following managed services:

Scaling

High Availability

Database backups

DB s/w patches

DB s/w installs

OS patches

OS installation

Server Maintenance

Rack & Stack

Power, HVAC, net

However, I argue that the metering of cloud database usage and the corresponding bills will eventually become significant enough for corporations to take notice. This is due to the fact that pay as you go model albeit granular is in fact only expected to increase dramatically as usage grows. Consequently, the cloud may no longer be the least expensive option. Higher metering and more monitoring along with dramatic increase in traffic add up to substantial costs while there is no fallback option to keep the costs under the bar. 

The fallback option to cut costs and make them more manageable is itself a very important challenge. What will money starved public cloud tenants do when the usage only accrues with explosion of data regardless of economic cycles? This in fact is the motivating factor to consider a sort of disaster management plan when public cloud becomes unaffordable while it may even be considered unthinkable today. 

I'm not touting the on-premise solution or the hybrid cloud technology as the fall back option. I don't even consider them as a viable option regardless of any economic times or technological advancement. The improvements to cloud services has leaped far ahead of such competition. Instead I focus on some kind of easing of traffic into less expensive options primarily with the adoption of quality of service for cloud service users and their migration to more flat rate options. Corporate spending is not affected but there will be real money saved when the traffic to the cloud is kept sustainable.
