It’s not something many people outside of IT think about but something nearly everyone in an organization relies on in the form of IT services, both internal and external, whether they know it or not. All organizations and, more specifically, all organizational initiatives and projects rely on IT resources at some level today. Which brings up some basic questions:
- How much IT infrastructure capacity do you have?
- How much IT infrastructure capacity do you need?
- Does your IT infrastructure have the capacity to support the next IT resource-intensive project?
- How do you get clarity on historical demand, predicted demand, performance, utilization, etc for your IT service delivery?
- How do you really know if your IT infrastructure utilization rates are improving?
- Can you measure and improve your ROI on IT investments?
- Can you properly measure the cost impact of an insource versus outsource decision?
There’s a good discussion on this topic specifically as it relates to IT capacity planning in this LinkedIn group thread. The first and most important step is understanding where you are today before you can make rational decisions about where you need to go and how to get there – like the old Yogi Berra quote “if you don’t know where you’re going, you might not get there”. But how do you determine where you are? What metrics do you use?
At 6fusion, we approach these questions from the perspective of IT as a utility (Side note: John Cowan, 6fusion Co-Founder and CEO, has a great 4-part series of posts on this topic GigaOm analyst Paul Miller has also recently published a white paper called “Metered IT: the path to the IT utility“ if you are interested in more detail). The take-aways from this approach as it relates to IT infrastructure and IT management in general are as follows:
- Pick a single unit of measure for IT resource consumption and stick with it. We like to use the WAC, but whatever you pick stick with it, because historical comparisons are key (see number 4 below) and if you change metrics your historical data loses relevance.
- Measure across all environments in use, whether those are virtual, physical, public cloud, private cloud, or hybrid cloud environments.
- Measure across all users, groups, business units, divisions – however your organization is segmented.
- Continue to measure at intervals appropriate for your business and technical requirements – could be every minute, could be every week, could be every month – the specific interval isn’t necessarily critical. What matters is that you continue to measure over time so you can compare, contrast and improve.
- Benchmark outside your organization – internal comparisons are good, but external comparisons and benchmarking are even better, particularly when you can benchmark against leaders in the field.
The IT industry is rapidly changing with the move to virtualization and the proliferation of public and private IT service providers. As organizations consider moving to either a public or private cloud solutions to host their corporate infrastructure, they need to gain a fundamental understanding of how they use IT infrastructure first. By adopting a utility metered approach to IT services, those organizations can gain a tremendous amount of insight into how their resources are being used, who us using them, and what they actually cost to run. With this knowledge in hand, the enterprise can make educated decisions on what type of services are needed, what they cost to produce internally, and whether or not they can be produced externally at more competitive rates or service levels. This approach allows IT to take a true business focused approach to IT and help drive value to the organization.
Shameless plug: 6fusion has been working with organizations to answer these questions for years with a combination of experience, expertise and innovative tools. We recently formalized a service to bring this approach to IT infrastructure capacity and costs analysis to market. You can download a sample output here by clicking the image below.

President Obama recently announced the launch of a new national awareness campaign to "encourage more Americans to move beyond passwords – adding an extra layer of security like a fingerprint or codes sent to your cellphone." The shift from single passwords to multi-factor authentication couldn’t be timelier or more strategic. This session will focus on why passwords alone are no longer effective, and why the time to act is now. In his session at 19th Cloud Expo, Chris Webber, security strateg...

Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?

Complete Internet of Things (IoT) embedded device security is not just about the device but involves the entire product’s identity, data and control integrity, and services traversing the cloud. A device can no longer be looked at as an island; it is a part of a system. In fact, given the cross-domain interactions enabled by IoT it could be a part of many systems. Also, depending on where the device is deployed, for example, in the office building versus a factory floor or oil field, security ha...

In addition to all the benefits, IoT is also bringing new kind of customer experience challenges - cars that unlock themselves, thermostats turning houses into saunas and baby video monitors broadcasting over the internet. This list can only increase because while IoT services should be intuitive and simple to use, the delivery ecosystem is a myriad of potential problems as IoT explodes complexity. So finding a performance issue is like finding the proverbial needle in the haystack.

The idea of comparing data in motion (at the sensor level) to data at rest (in a Big Data server warehouse) with predictive analytics in the cloud is very appealing to the industrial IoT sector. The problem Big Data vendors have, however, is access to that data in motion at the sensor location. In his session at @ThingsExpo, Scott Allen, CMO of FreeWave, discussed how as IoT is increasingly adopted by industrial markets, there is going to be an increased demand for sensor data from the outermos...

Between 2005 and 2020, data volumes will grow by a factor of 300 – enough data to stack CDs from the earth to the moon 162 times. This has come to be known as the ‘big data’ phenomenon. Unfortunately, traditional approaches to handling, storing and analyzing data aren’t adequate at this scale: they’re too costly, slow and physically cumbersome to keep up. Fortunately, in response a new breed of technology has emerged that is cheaper, faster and more scalable. Yet, in meeting these new needs they...

When it comes to cloud computing, the ability to turn massive amounts of compute cores on and off on demand sounds attractive to IT staff, who need to manage peaks and valleys in user activity. With cloud bursting, the majority of the data can stay on premises while tapping into compute from public cloud providers, reducing risk and minimizing need to move large files. In his session at 18th Cloud Expo, Scott Jeschonek, Director of Product Management at Avere Systems, discussed the IT and busin...

More and more companies are looking to microservices as an architectural pattern for breaking apart applications into more manageable pieces so that agile teams can deliver new features quicker and more effectively. What this pattern has done more than anything to date is spark organizational transformations, setting the foundation for future application development. In practice, however, there are a number of considerations to make that go beyond simply “build, ship, and run,” which changes how...
