  • Sysadmins, Check Out Google’s Data Center Papers

    If you’re an enterprise architect or systems administrator, you know how a data center works—and if your career spans several years, chances are good that you’ve dealt with some pretty massive systems. But it’s hard to think of infrastructure more massive than what Google just revealed.

    “From relatively humble beginnings, and after a misstep or two, we’ve built and deployed five generations of datacenter network infrastructure,” Amin Vahdat, a Google Fellow, wrote in an Aug. 18 posting on the Google Research Blog. “Our latest-generation Jupiter network has improved capacity by more than 100x relative to our first generation network, delivering more than 1 petabit/sec of total bisection bandwidth.” That means 100,000 servers communicating “with one another in an arbitrary pattern at 10Gb/s.”

    Google built the system out of necessity; traditional networking hardware simply couldn’t scale to meet its enormous needs. The company has released four papers on how it managed to customize bandwidth to serve thousands of applications, design data center network topologies, deal with epic congestion and latency, and build a muscular cluster manager. For any tech pro interested in data centers, they’re well worth reading for an idea of how far networking and server technology has progressed—even if you have no intention of working with a system as large as Google’s.

  • AWS VIDEO: Application Portfolio Migration

    This is a very interesting video from Miha Kralj, Principal Consultant, AWS Professional Services that was presented at AWS re:Invent 2014, this past November.

    What is most interesting is Miha’s take on CMDB applications. Miha stated “CMDB’s lie, if you think you have anything good or meaningful information in your CMBD, good luck. We didn’t find anything of use and don’t trust anything that is in the CMBD. Agents are not really being taken care of in CMDB’s. Most enterprises already have a dynamic virtualized infrastructure, and CMDB’s are just too slow to catch up. CMDB’s are a snap shot in time, and that snap shot in time can’t be done once a week. Enterprises say “that snapshot is two weeks old”. Do you know how much I can spin up and spin down on Amazon in two weeks. That why CMDB’s won’t work to prepare for migrations.”

    We get the question from many analyst, systems integrators and customers as to why they need our tool instead of using their existing CMDB. Miha’s presentation gives a great explanation as to why tools like our CloudScape tool is very valuable during the discovery process and why using it ongoing is critical to ongoing cloud projects
