Many software suppliers seem to be talking about how they do
capacity management these days.
In the
server area of infrastructure management alone you have:
·
Established businesses that have been offering data
capture, capacity database and a range of capacity reporting for some
time. Typically these businesses have
started in one technology area such as mainframe or Unix and spread their
coverage across platforms as IT has evolved.
·
Point solutions that analyse current performance
and make tuning recommendations
·
Framework providers touting capacity management
as one of the modules within their toolset.
Often this is the result of acquisition of a third party capacity
management product that then gets increasingly integrated with their framework
·
SaaS/Cloud solutions that take in data from one
or many environments
In this blog, I’d like to consider the first two of these
options.
Common with environments that support rapid provisioning, is
confusion between the first and second areas.
Both groups talk of capacity management, but the focus of what capacity
is being managed is different. This is
not the metrics or applications that are being watched, more the time frame and
nature of capacity events that are being reviewed.
In days gone past, one might have talked of this as the
difference between capacity management and performance management. As everyone seems to be using the terminology
much more interchangeably these days, perhaps it is better expressed as
strategic capacity management and operational capacity management.
Operational capacity management
is based on measured performance metrics and recommends operational changes,
e.g. moving VMs.
Strategic capacity
management is based on taking action well in advance to remove the risks
and problems before they occur.
I’ll be taking a look at both of these types of capacity
management on Friday, in the meantime why not sign up to our Community and access
