Bracing for the failure of your private cloud architecture

Grazed from TechTarget. Author: David S. Linthicum.

A common misconception among cloud consumers is that private cloud architecture doesn’t have the same issues that arise with public cloud services. Due to its private nature, some believe that security is a given and failure is not an option. Those users learn the hard way that is not the case. But why do private clouds fail?

The core reasons that private clouds fail include a lack of planning on the part of IT and a failure to understand that cloud security requires attention and maintenance. Private cloud architecture is typically much more dense and intense than traditional systems, with processing and storage concentrated within a small cluster of servers. Most patterns of failure link back to three problems during private cloud builds. There are two types of clouds: clouds that are managed properly, and clouds that don’t work…

1. Re-using existing hardware

Many private clouds are built using repurposed hardware and some existing software licenses. While this seems like a way to maximize the value of your private cloud, you’ll find that the hardware requirements for most private cloud OSes are demanding. If hardware doesn’t have enough horsepower, the system will begin thrashing, which causes poor performance and likely a system crash. These service interruptions may cause users to lose confidence, and the private cloud fails…
