Here are three cost-saving ideas and technologies for your
organization’s computer networks and information technology:
- Voice over IP (VoIP) Telephony. Voice over IP is having your
corporate telephones communicate over your data network along with your
PCs, laptops and servers. Significant savings can accrue by reducing
the redundancy of your telecommunications infrastructure (cabling,
switches and routers, telecommunications lines). But VoIP isn’t for
every organization. How do you determine if it’s right for yours?;
- Virtualization. The “virtual” in virtualization is in
emulating entire computers – PCs or servers – within the operating
system of a single computer. Savings accrue here through sometimes
dramatic reduction of needed hardware. Virtualization is not an easy
technology to adopt, but properly planned and executed, the payoff can
be very great.;
- Lifecycle Management. Computer hardware and software has
predictable lifecycles. Managing computer hardware resources to
optimize their lifecycle while avoiding unpredictable and unnecessary
failures saves organizations direct costs in reducing necessary IT
services and indirect costs in the form of unscheduled downtime.;
Each of these technologies and management concepts can generate
substantial IT savings for your organization. But each of these ideas
requires careful planning and execution to realize savings, and to
prevent technology disaster. Here are some of the issues involved with
each of these cost-saving paths:
Voice over IP. Cost savings was one of the original benefits
of VoIP. At a bare minimum, VoIP requires half of the CAT5/6 cable
investment. However, the greatest benefits can come from reduced
telecommunications links, like T-1/PRI connections, as both voice and
data systems can use a single link or set of links. Older PBX's and Key
systems required their own T-1s to access the Public Switched Telephone
Network (PSTN). Deploying VoIP, especially in new offices, leverages
the data circuit (T-1 or better) to handle voice calls. Other cost
benefits can come from using IP softphones (which can turn nearly any
computing device into a phone) or VPN phones (the ability to have your
office phone ring at your home or other remote location), as these
extend communications to remote users.
VoIP projects will often fail without excellent computer network
design to accommodate both data and voice applications, a careful
pre-installation analysis of the environment and needs of the
organization, and particular attention to bringing the user community up
to speed on the technology. Poor understanding of the VLANs in an
environment, as well as less-than-optimally designed traffic
prioritization can significantly degrade performance of both an
organization’s phone system and IT system, once they go live.
Virtualization. It's not just for the datacenter anymore.
This technology has been used in large datacenters for years, permitting
datacenters to quickly and inexpensively set up resources for clients.
However, the technology has matured to the point that many organizations
can implement it internally and derive the significant cost savings and
flexibility associated with this technology.
There are numerous applications for virtualization in the office to
save money on physical server iron, or even desktop development. Domain
Controllers, DNS/DHCP, print servers are the low-hanging fruit.
Deploying front-end servers for Sharepoint, Blackberry Enterprise are
other ways to cut down on physical servers. IT departments can test new
operating systems like Windows 2008 or Windows 7 without dedicating a
physical system. Companies can maintain older OSes like Windows 98, NT,
2000 for testing client-facing websites or applications. Mac users can
install VMWare Fusion or Parallels to run a Windows VM inside of OS-X,
as a simple way to take advantage Windows applications. Schools can
deploy VMs for student use, and then replace the VM when it is damaged
or virus-infected.
Microsoft has upped the ante with Direct Access. This virtualization
technology permits corporate Windows 7 users (assuming a Windows 2008
sever environment) to access their network resources without creating
VPN connections. The greatest benefits are the ability to be connected
to your organization as long as the Internet connection is fast
enough.
Not every application is a good candidate for virtualization. Some
applications are NOT appropriate for virtualization. Distinguishing
between applications that are virtualized well and those that are not is
a critical task in developing an overall strategy.
Even once various applications and functions have been sorted
through, virtualization is not an easy thing to implement. If not
planned well and executed precisely, it can lead to catastrophic loss of
network resources and large amounts of unscheduled downtime.
Lifecycle management. Optimizing the maintenance of your IT
investment is critical task to reduce IT costs and maintain them at
lower levels. Tracking hardware and software service contracts,
maintenance agreements and replacing systems when they reach end-of-use
helps keep an organization running smoothly. In many environments, a
3-year lifespan for a laptop or a desktop is appropriate, while servers,
routers and switches can last for 4 - 7 years before being replaced with
newer technology.
This approach may seem counter-intuitive – replacing resources before
the absolute end of their functional life. However, organizations that
don’t practice lifecycle maintenance incur significantly higher direct
costs from unplanned, unbudgeted emergency IT services to repair or fix
or replace components at unscheduled times and inefficient use of
maintenance resources. Organizations also incur high costs from
unplanned downtime, and cannot reap the benefits, both in terms of
initial outlays as well as total cost of ownership in standardized
hardware and software purchasing.
Critical to good lifecycle management are the tasks of determining
the lifecycles that best suit the needs of your organization, developing
a standardization plan that meets your requirements, selecting the
proper tools to manage resources and implementing and maintaining the
proper procedures for the lifecycle management of a particular
organization.
