We all try to do it, we sometimes succeed, but the increased density of workloads escapes many folks, whether they are in a cloud or using an on-premises virtual environment. Are there ways to help us gain more density within our environments? Is it still fear that keeps us from doing so? Are there real issues we still need to solve? Why are most environments running with CPU to spare? Is there still a fear of running too many things on any one system?
Since the inception of the modern software industry in the mid-1980s, the management software industry has been led by the big four: IBM, BMC, HP, and CA. Due to the needs of the software-defined data center and the cloud, a new set of leaders and innovators has emerged.

In Understanding the Value of Unique Management Data, we pointed out that tools that collect unique data about the performance of infrastructure and applications are more likely to be able to provide you the value you want than tools that just rely on commodity data. In this post, we expose the most frequent marketing lie in the management software industry. Continue reading Real-Time Monitoring: Almost Always a Lie
A very interesting thing happens as your vSphere environment scales up.

You teenager takes the car out for a drive. Your teenager does an hour of driving and comes back with an additional 30 miles on the odometer. Your teenager also comes back with a speeding ticket for doing 60 MPH in a 30 MPH zone. When confronted with this unacceptable behavior, your teenager responds that their average speed while driving the car was only 30 MPH and that the police officer was “unfair” for focusing only on the peak and not the average.
