When executing an effective digital transformation strategy,
management is tasked with placing the right workload into the most appropriate
IT environment. This represents a shift from buying parts for self-assembly to
composing services through self-serve consumption and pay-per-use models. Quite often this transition also leads to the
adoption of software defined environments across the enterprise infrastructure.
Software defined infrastructures do, however, bring with
them some very
unique challenges. Many of the most prevalent issues are centered around
the relatively immature state of the technology itself. The most significant
aspect of this challenge is the lack of industry standards for device control. Control
software must know the status of all network devices and trunks, no matter what
vendor equipment is being used. While OpenFlow
stands today as the de facto software defined networking standard, it is a
unidirectional forwarding-table update protocol that cannot be used to
determine device status. It also doesn’t allow for the programming of port or
trunk interfaces. A second critical issue is the lack of business process or
enterprise IT policy definition capabilities.
This shortfall often leads to resource over provisioning caused by
automation rules that deploy “just in case” instead of “just in time”.
When taken together, the two latter problems heighten the
risk of vendor lock-in. This issue
was highlighted last year by Major
General Sarah Zabel, Vice Director of the Defense
Information Systems Agency. This
military organization deals with 2,400 trouble calls, 2,000 tickets, 22,000
changes, and 36 cybersecurity incidents every day. Its global network
interfaces with owned and managed networks from other military departments and
services providers. When addressing the Open Networking User Group,
Major General Zabel stated that the agency suffered from vendor lock-in and too
many devices.
“We need an area where vendors accept the fact we need a path
away from their solution…We need less dependence on hardware and to be able to
work with more software."
Another important but widely ignored challenge is the need
to build organizational buy-in, a problem that is often accompanied by business
process changes. According to Neal Secher, managing director and head of network
architecture at BNY Mellon, "You need to partner with your business and
show them the value. There's a snowball [effect] that will add value and allow
you to add more automation. You need to prove through evidence that it works
and won't hurt the business."
Understanding how to select, configure and operate within
this new paradigm requires new technology, new technical skillsets and new
management techniques. This trifecta of change cannot be easily assimilated
within most large organizations. This is why IBM
IT-as-a-Service (ITaaS) can often provide critical advice, assistance and
technology.
ITaaS is an approach for defining and consuming digital
services through a hybrid cloud infrastructure. This approach has often shown
itself as the most cost effective path toward workload optimization. When used
as part of a holistic strategy, hybrid cloud infrastructures can deliver
multiple levels of value by:
- Delivering programmable, virtualized and application-centric networking capability;
- Managing the corporate mobile infrastructure and Bring-Your-Own-Device (BYOD) initiatives;
- Modernizing and optimizing the IT security program for identity, application, data, network, and endpoint security in a way that manages risk and achieves compliance; and
- Enabling a shift of executive focus from infrastructure maintenance towards the creation of innovative products and services.
Hybrid cloud environment alone, however, aren’t able to maximize
the value of digital transformation. To
do that you may also need to consider cloud brokerage capability. This tool can be used to plan, procure,
govern and manage all IT services across all cloud models. To avoid vendor
lock-in, this service can also be exercised across multiple IT service
providers.
Software defined infrastructures can deliver infrastructure
optimization and enhanced IT services at a reduced cost. Organizations that opt
to take advantage of this new operational model should, however, seriously
consider taking the ITaaS route.
