Remote Access
Remote access is one of the
most important, yet possibly most overlooked,
tools a company can use to reduce costs
while both enhancing and simplifying its
operation for employees and customers. Design
and deployment of remote access systems
is one of many services offered by CyrusOne
that can be hosted in its Enterprise Data
Center. CyrusOne often designs remote access
systems that use VPN technology, providing
users with access to their systems and applications
in a highly reliable, secure and cost-effective
manner.
What is it?
Remote access technologies provide access
to a company’s core information systems
and applications from remote locations.
Here are some examples of how it can work:
- A salesperson orders an out-of-stock
item and learns the anticipated delivery
date while at the counter with a customer.
- A project manager modifies critical
project data and instantly updates personnel
at several remote offices.
- A telecommuter works from home, saving
the cost of office space at company headquarters.
- A user in one part of the world works
on a project with a team located clear
across the globe.
What are the
benefits of remote access?
A well-coordinated remote access plan brings
your business closer to your customers and
more customers to your business. When you
put essential information into the hands
of the people who work most closely with
your customers, they have the tools necessary
to build better customer relationships and
reach more prospects. Other benefits of
remote access include:
- Real-time, instant access to information
from almost anywhere
- Improved productivity and less downtime
waiting for responses
- Greater flexibility away from the office
- Reduced costs
- Enablement of workflow during a business
disruption or disaster
How do most
companies use remote access now? Unfortunately,
the majority of businesses are not taking
full advantage of the many benefits they
could achieve with more judicious use of
remote access. In fact, most of those companies
that employ remote access make it available
only to support technicians and a few key
personnel.
Why hasn’t
remote access become more widely accepted?
With so many potential benefits, what is
holding everyone back? A general lack of
understanding regarding remote access technology,
security concerns and confusion on the business
benefits of remote access are just a few
of the reasons remote access hasn’t
become more widely accepted.
What are some
of the technology issues?
Currently, analog and ISDN dialups are still
widely used throughout corporate America.
The downside associated with these technologies
involves long -distance charges and slow
connection speeds. Even if the application
has an intuitive graphical interface, most
users find analog connections too slow and
frustrating. While ISDN provides greater
throughput than dial-up, some applications
require downloading of large amounts of
data and faster speeds. ISDN may also result
in long-distance charges.
Are there any
better technologies available?
Because of the issues described above, many
companies are now migrating to an Internet-based
platform to take advantage of faster, lower-cost
technologies such as cable modems and digital
subscriber line (DSL). Cable modems and
DSL technologies provide remote users access
to more bandwidth, and thus greater speed.
The Internet platform is secured through
the use of a virtual private network (VPN),
which creates a secure connection by “tunneling”
through the Internet and securely transmitting
the information so that only authorized
users can view it. There has been considerable
improvement in remote capabilities and costs
during the last few years as VPN technology
has matured. As a result, the VPN market
is expected to triple by 2006, according
to market researcher IDC.
What are the
advantages of VPN?
VPN technology provides remote users fast,
secure access to a company’s core
systems – applications, databases,
etc. The data in those systems is encrypted
between two end-points (routers, firewalls,
servers or VPN devices) from the time it
leaves the corporate network until it arrives
at the home worker’s desktop. VPN
is gaining greater acceptance as the technology
becomes more reliable and more robust with
greater security features. Which brings
us to the issue that most companies are
troubled by today - the security of their
confidential data transmitted through the
Internet.
How are security
concerns being addressed?
Obviously, information is the lifeblood
of most companies, and internal information
must be kept especially confidential. Maintaining
security while still allowing employees
the access they need is an ongoing challenge.
Fortunately, there are several ways a company
can address these issues. First, a company
must develop and enforce a comprehensive
security policy. Second, security technology
should be layered so that a single breach
does not give an intruder unlimited access.
Finally, security systems must be regularly
audited to ensure only those that require
access have access.
Are there other
technologies that support remote access?
Several technologies have been developed
that allow bandwidth-intensive or highly
secured applications to be accessed remotely.
Two of the most common are Citrix® and
Windows Terminal Server®. These technologies
allow most of the application processing
to occur in a single location, passing small
amounts of information to the remote user.
A Citrix or Terminal Server can be loaded
with specific applications and set up in
a limited access area of a company’s
network. Each user securely logs on to the
limited access area, and then authenticates
to the Citrix or Terminal Server.
What makes these technologies effective
is that the user experience is very good
since the application is presented in a
native or original format within the browser
window. IT organizations appreciate these
technologies because they do not require
the application to be rewritten for a new
transmission technology. Maintenance is
streamlined because support technicians
update the application
once (on the server), not on every desktop
that connects to the server. Access to applications
can be accomplished via user policy on the
server. Only the application has access
to the database through a firewall or some
other security tool. Citrix and Terminal
Server also work well as key components
of a business continuity or disaster recovery
plan. In sum, these technologies provide
satisfactory data -rates to a number of
users when bandwidth is limited. Because
more applications are now browser-friendly,
the learning curve is shorter and users
enjoy greater flexibility and access.
How does remote
access fit into Business Continuity and
Disaster Recovery Plans?
Without question, every company should have
a Business Continuity and Disaster Recovery
plan. While most IT budgets are tight, the
evolution of remote management technologies
has allowed IT organizations to get a two-for-one
bargain by delivering a single solution
that supports both remote access and disaster
recovery. During a major disaster, most
companies
will work with a limited staff, and Citrix
and Terminal Server can be used as part
of a Business Continuity or Disaster Recovery
solution to provide the necessary
application functionality while users access
their systems through secure remote access
technologies utilizing VPNs. Under this
scenario, users don’t necessarily
need to be at the same location as the servers.
Users could work from home or from temporary
corporate office space as long as they have
an Internet connection.
What’s
the best way to configure a remote access
system?
Products can be combined to provide the
necessary functionality. For example, a
VPN connects to a remote access network
using Citrix or Terminal Server to provide
access to databases or applications. In
this manner, a user has secure access to
an application or database and the data
is encrypted from one end-point to the other.
This same configuration works for remote
or branch offices. Furthermore, a company
could have remote offices or branch offices
connect to a business continuity or disaster
recovery site via a VPN tunnel. If their
primary site went down, access to the backup
site would be available.
Will the opportunities
for remote access continue to expand?
According to research firm Cahners IN-Stat,
more than 32 million people will telecommute
this year. There has been steady growth
of 7% each year for the last decade. With
the rise of DSL and cable modems, this number
should greatly increase over the next few
years. In addition, Yankee Group estimates
that 75% of U.S. households currently have
access to either cable modem or DSL service
and by the year 2005 this number could be
as high as 85%.
What’s
the bottom line?
Remote access has never been faster or more
secure, making it easier than ever for companies
to take advantage of the growing trends
toward telecommuting and business continuity.
As more households and branch locations
become capable of supporting the technology,
it’s time for companies to consider
remote access as an integral part of their
business philosophy. With servers in hardened
secure data centers, users can work at remote
offices or from home and still have access
to core corporate information. This flexibility
becomes increasingly important as users
seek to conduct business online in front
of customers using laptops, PDA’s
and other portable devices. Customers will
appreciate and begin to expect that their
suppliers have access to all required resources
needed to complete a transaction in a timely,
service-oriented manner.
