Public Sector BYOD Series: Streamline IT for a Mobile-Ready Work Strategy

For this week’s final Public Sector BYOD Thursday post, I wanted to discuss a survey  that illustrated what employees want and need when it comes to IT in the workplace:

  • Control over the work experience—the ability to use technology to personal preference, in ways that improve productivity and enhance job satisfaction.
  • Choice when it comes to devices and the ability to use preferred, personally owned devices to complete work-related tasks.
  • Flexibility to perform personal activities at work and work activities on personal time.
  • Mobility that enables anytime, anywhere connections to colleagues, customers and partners.

Are Overlays the Duct Tape of Networking?

Duct tape is pretty amazing stuff because its versatile and easy to use.  That being said, sometimes, that versatility and ease-of-use means it gets used at times when maybe it shouldn’t.

This thought came to mind a couple of weeks ago at VMworld.  Over the course of the show, I had a number of conversations with folks about tunneling and overlay network.  For many (mostly non-networking) folks, it seemed like the best thing since sliced bread—it gave them the holy grail—flexible, agile, one-demand connectivity without having to talk to the network folks.

From a networking perspective, its kinda funny, since the concept of tunnels is a decades old technology. It’s always played a legitimate role in a comprehensive networking strategy (MPLS and IPsec VPNs for example) so its cool to see an old concept find new applications.

However, lest we be lulled into blissful slumber by the unicorns playing lilting melodies through their horns, its good to remember, as with pretty much everything in IT, there is no free lunch.  While overlays networks make life simpler for the server admin or the virtualization admin, there are a couple of things to bear in mind.

From an operational perspective, the overlay environment becomes a second network that needs to be managed—often a dumber, less instrumented network.  Somewhere, someone still needs to maintain a fully functioning, highly available, secure, properly traffic-engineered network that underpins that virtualized connectivity. Think of this as the difference between your checkbook and your checking account—just because you can write a check doesn’t mean there is money in the account to cover it.

Now, if you are not a networking dude or dudette, your first reaction may be “why do I care?”  Well, when you start seeing performance issues on your tunnel, you start to see intermittent drops on your tunnel, or you need to demonstrate auditable regulatory compliance, then you start to care.  While some folks propose that the underlying network becomes irrelevant once you start using overlays, the truth is that the strengths and weaknesses (performance, availability, security, manageability, etc.) of the underlying physical network are going to manifest themselves in in whatever rides on top.  While overlay technology is undeniably useful, having an approach that leverages the intelligence of the underlying infrastructure (assuming any exists) is going to pay off in the long run.

Security Industry Visionary Joins Cisco

We are in the middle of several major market trends and transitions, including mobility, cloud and virtualization. Security is at the center of these massive transitions, and our customers tell us that they want simplicity and seamlessly integrated solutions for their network architectures. These industry disruptions require new thinking to create innovative technological solutions that will solve our customers’ biggest problems.

Enter Bret Hartman.

Bret has joined Cisco as the new Chief Technology Officer (CTO) for the Security Technology Group, which encompasses all of Cisco’s core security products. For Cisco, Bret will define our overall security technology strategy, particularly as it relates to how security technology integrates across the network infrastructure. Ensuring that our strategy transitions into value-added customer solutions will be critical as we move to an integrated security architecture that leverages the network.
