TechWiseTV 120 Defending the Data Center

September 20, 2012 at 10:30 am PST

We had to dig further, past our initial meetings internally and determine what would make this particular story unique from previous ones we have told this year.  As it turns out, we had plenty of material to share but three really good shows done earlier, now provide great context for appreciating the innovation we talk about in this one.

Check out: Fundamentals of High End FirewallsFundamentals of Intrusion Prevention and (TechWiseTV 115) Firewall Reinvention with the ASA-CX

So topically, Security in the Data Center is an easy hit of course.  It almost sounds like an Oxymoron as many are convinced it is some kind of insurmountable obstacle. Nothing could be further from the truth.   It seems to top many lists.  [Watch 'Defending the Data Center' Right Now.]

As Cisco broadens the tool set with new models and deployment options, we broke this one down along party lines:

What’s your Cloud IQ?

July 25, 2012 at 9:00 am PST

Two of my favorite geeks are presenting a workshop today on Bringing the Cloud to your Remote Offices.  Jimmy Ray is hosting his ‘brother from another mother’ (as we fondly refer to him) Matt Bolick.  Matt first blew our doors off back in 2009 as we featured the then new ISR G2 in our ‘Routers are Dead…Long Live the Router show (now retired).  Well, Matt was a featured guest recently on another big show we did, the Cisco Cloud Intelligent Network.   You can see Matt’s segment on Application Visibility and Control from that show right now as a great pre-study for the workshop above.   I also recommend our recent ‘Fundamentals of the Cloud Services Router’ as a secondary study resource.  Matt was instrumental in our writing and creation of this tool as well and I think you will find it valuable.

Heres the thing -- The Cloud and the Network are very co-dependent.  The network is poised for incredible leaps of intelligence now more than ever with this pressure from cloud implementations being quick to reveal weakness. I have even heard where the WAN has been re-defined as “Weak Area Network.”  Why?  Poor performance, inadequate security, lack of visibility and complex management, just to name a few An intelligent network endows the WAN with the  efficiency of cloud and and the confidence of a private network.

Overlay Transport Virtualization

July 24, 2012 at 10:16 am PST

Fresh from the lab, Jimmy Ray takes a question on OTV or Overlay Transport Virtualization.  This layer 2 Data Center Interconnect technology is growing in popularity as deployed on the Nexus 7000 as it promises transparent workload mobility, business resilience and superior efficiency with computing resources. This could be THE technology for those of you overcomplicating your network design or simply not attempting certain architectures for you did not know this could be done.

We featured OTV quite awhile back in one of our earlier Fundamental animations.  See if this also helps you.   Read More »

Networking 101: DNS Revealed

June 1, 2012 at 5:49 am PST

Two great new ‘Networking 101’ videos now available.  This series is great for anyone needing a quick refresh or touch up on the basics and these two both focus on DNS.

DNS is key to making the Internet accessible to us humans. It’s how we can connect to techwisetv.com without needing to know anything complex from anywhere in the world. How does it know how to do this? DNS can be a complicated topic but understanding the basics does not have to be.

Taking it a step further, DNSSEC is a suite of IETF specifications designed to guarantee the authenticity of data obtained from the domain name system (DNS). Although not designed for confidentiality of the data, this protocol is a great answer for many of the ills that threaten the simplicity of the Internet. Chief Geek Jimmy Ray Purser arms you with how it works and why deployment is not growing as fast as it should be.

Fundamentals of 802.11ac

May 12, 2012 at 7:44 am PST

We released our latest in the Fundamentals series earlier this month and it is trending quite well.  The 802.11ac standard sounds like a step backwards alphabetically…but it will soon be an incredible step forward forward for WiFi once it is ratified by the IEEE. Watch this latest fundamentals to get comfortable with the truth. 802.11n is still your best bet for 2012 and into 2013 as we continue to partner on the standards process but the future is bright indeed!
