Packet Pushers Podcast on Scalable Cloud Networks with VXLAN

November 28, 2011 at 4:57 am PST

Podcast Greg Ferro and Ethan Banks from PacketPushers.net have released another in-depth podcast, this time on how to create scalable cloud networks with VXLAN. VXLAN, if you recall, is a multi-vendor effort to increase the number of logical networks that can be created within a cloud environment, and overcomes the challenges of using VLANs when separate tenants and application instances all need their own logical domains.

How to Make the Business Thankful for IT. Give them Apps!

November 23, 2011 at 11:46 am PST

Think about it, when was the last time the business said “thank you” to IT? It’s probably been a while. Unfortunately, all too often we hear complaints that IT is too slow, or that IT is the department of “no”.

Deploying a private cloud is one way to help turn IT into the department of “yes”, with faster and more responsive IT service delivery. The customers of Cisco Intelligent Automation for Cloud have compressed the cycle time for IT provisioning from weeks to minutes. That means that project managers and application developers no longer have to wait for IT – they can speed up their projects and get business applications up and running more quickly.

And if there’s one golden rule to remember for your private cloud solution, it’s that the business wants apps. They’ll be thankful if you can provision and manage their applications in a cloud environment with consistency, reliability and speed.

So if you’re interested in on-demand application delivery for your private cloud, check out this presentation from Cisco Intelligent Automation and our ecosystem partner rPath:

Cisco Nexus1000v: LASIK surgery for the network admin

I finally took a leap of faith and had LASIK surgery done recently, and without a doubt it’s been a life changing decision.  The daily hassle of glasses and contacts are gone, and my vision is now 20/15…it’s like going from regular TV to HiDef!  Of course these benefits came with a cost, requiring investments both financial and mental.  The financial cost was easy enough thanks to no interest payments, however the mental cost required a careful weighing of risk vs reward and a bit of blind faith (no pun intended).  In the end, trust in the technology and the doctor, and the belief that I could find my happy place for 15 minutes to endure the procedure was enough to take the leap.  Looking back it was one of my better life decisions.

Shortly after my procedure I was on site at a customer who was implementing a Vblock, and Cisco was engaged for UCS optimization services to follow up the install.   For those new to integrated infrastructure solutions, a Vblock is a pre-integrated and tested infrastructure stack with various components across compute, network, and storage.  My favorite component hands down is the Cisco Nexus1000 This product replaces the VMware vSwitch functionality with a feature rich Cisco switch powered by NXOS, which this particular customer had no knowledge of.   Well,  I’m a huge fan of the product, and I knew they would be too once they came to understand it’s use cases and capabilities.   I gave their network and server admins a 4 hour overview covering everything from architecture to troubleshooting.  The light bulbs went on and they were exchanging smiles about 10 minutes into the presentation when I started talking about the non disruptive operational model and VN-LINK concepts.  One of the network admins interrupted me and said “ are you telling me I can get clear vision to the VM level without the hassle of dealing with these guys” as he pointed at the closest server admin.  I immediately thought of my new eyes and chuckled at the thought that server admins apparently were as annoying as glasses or contacts to deal with on a daily basis.
