IT Change Management 101

You can't change what you don't know

IT shops continually struggle with keeping resource documentation up to date. Too often IT departments seem resigned to accept mediocre results, as if the world conspires against them. Resource tracking is a prime example of this.

Fundamentally, the different organizational aspects refuse to comply with these manual processes to keep a CMDB updated. Furthermore, advancements in virtualization have made the situation worse, as software resources have been severed from physical resources. Traditional resource tracking methods are further confused as the virtual resources change physical location over time.

This reinforces the protests that an application's dependency profile is too complicated to be 100 percent accurate. Over time, IT has simply accepted the fact that it is totally impractical to keep the physical architecture records of systems up to date manually. Instead of trying to maintain the documentation, it is generated when needed through a time-consuming trial-and-error process, and by the time it is done, it is hopelessly out of date.

Not only is this an inefficient use of people's time, it's no way to manage some of the most important resources in an organization. These IT resources have become a digital backbone upon which most organizations are totally dependent for their very survival. The cavalier attitude toward managing IT resource inventory is dangerous at best and can prove to be catastrophic.

For instance, it's just a matter of time until the next large outage occurs. Despite the best-laid disaster recovery plans, technology has an uncanny ability to fail in unexpected ways; the combinatorial possibilities are immense. Having accurate application maps can make the difference between being the hero and goat. If individual self-preservation isn't motivating enough, there are other practical organizational reasons to keeping this information available: datacenter moves, chargeback models, and consumption analysis to name a few.

Generally this lack of inventory control has been accepted as the status quo despite the clear risks. In no other industry would such poor controls be acceptable. Imagine Wal-Mart's CEO explaining a lack of understanding of store inventory to Wall Street analysts. If such a story broke, he'd be out of a job before the ink dried. IT management shouldn't be allowed to get away with it either.

This is exceedingly frustrating, as application dependency mapping tools have become mature offerings. An application-dependency mapping tool uncovers the otherwise hidden relationships between applications and infrastructure resources. In our experience as former IT practitioners, we have implemented such capabilities. Our main goal was to get a better handle on inventory management and resource relationship for a datacenter move, but we quickly realized that there were many additional benefits we could take advantage of:

  • Identification of idle servers for reclamation (we were shocked at how many)
  • Identification of legacy infrastructure that poses a security threat (such as Windows 95/98)
  • Identification of production servers using development or test resources
  • Identification of changes to an environment over time, especially useful for figuring out "what changed" for debugging purposes
  • In addition, these tools provide a repository that supports a cradle-to-grave resource management policy. Firms should export this information into both a CMDB and a living blueprint platform for change management and system maturation purposes.

    IoT & Smart Cities Stories
    The hierarchical architecture that distributes "compute" within the network specially at the edge can enable new services by harnessing emerging technologies. But Edge-Compute comes at increased cost that needs to be managed and potentially augmented by creative architecture solutions as there will always a catching-up with the capacity demands. Processing power in smartphones has enhanced YoY and there is increasingly spare compute capacity that can be potentially pooled. Uber has successfully ...
    The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
    We are seeing a major migration of enterprises applications to the cloud. As cloud and business use of real time applications accelerate, legacy networks are no longer able to architecturally support cloud adoption and deliver the performance and security required by highly distributed enterprises. These outdated solutions have become more costly and complicated to implement, install, manage, and maintain.SD-WAN offers unlimited capabilities for accessing the benefits of the cloud and Internet. ...

    As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
    Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
