My team is moving hundreds of applications to our new Application Centric Infrastructure (ACI) platform, and network dependency mapping is the first step in this migration. Most of Cisco IT’s applications are three tiered with web and middle tier residing on the same Java Virtual Machine (JVM) connecting to a database.
A typical application may have one or more JVMs that connect to one or more databases. Sometimes the databases internally connect to other databases. Over the last five years, we have heavily invested in Services Oriented Architecture (SOA) and thus have JVMs running web services. These web services are consumed by one or more user interfaces (UI). Some of these applications have jobs that run on our Cisco Tidal Enterprise Scheduler (TES). Read More »

By 2020 75 percent of all companies will be fully digital. The huge shift to a fully digital ecosystem has accelerated over the last couple of years, resulting in Fast IT, which is the new operating model for Cisco IT. The 3rd annual Data Center Day in Allen, Texas, could not have been a better showcase for this new model with its theme, “Disrupt or be Disrupted!” About 130 Cisco customers from every market segment, and in total more than 300 people, attended the Data Center Days on April 13th and 14th.

In July 2014, Cisco IT turned on the Application Centric Infrastructure (ACI) fabric for the first time in our San Jose engineering data center. Since then, we’ve been busy building out the ACI fabric in our U.S. production centers and beginning the process of migrating workloads. In phases, we’ll migrate our global infrastructure footprint to ACI within two years. Running on our internal cloud platform called Cisco IT Elastic Infrastructure Services (CITEIS), ACI provides flexibility and elasticity across the data center that wasn’t possible before. So far the results have been better than even we expected. Read More »

I like touring Data Centers. Whether it’s a makeshift space with out-of-control cabling or a state of the art, innovative facility, I’m always curious to see how companies accommodate their computing equipment and tackle the inevitable challenges of space, power and cooling.
Ten years ago I visited a then-new Data Center in the western United States that had several interesting features. Two elements – and the moments I discovered them – still stick with me.
