A decade ago, data centers were much smaller, and applications were typically huge, monolithic affairs, deployed using the classic client-server model. The core-distribution-access architecture model for networking served those applications well in data centers with north-south data flows because the application was hosted on a single server that communicated with clients outside of the data center.
In contrast, applications nowadays are built using microservices, which run on different servers within the data center. Microservices must communicate with each other to achieve the functionality of the wider application, requiring more east-west traffic than their monolithic counterparts. So the microservices of today’s applications require a change in data center architecture, namely to spine-leaf deployments with two switching layers.
Another change that is seeing increased adoption in the data center switching space is the use of disaggregated solutions. These types of solutions distance themselves from integrated hardware and software provided by a single vendor in exchange for bare metal or bare-metal hardware appliances and separate network operating systems (NOSs).
This approach allows data center operators more flexibility and control over the networking infrastructure. While we don’t expect to see all data center infrastructure shifting towards disaggregated solutions overnight, vendors who focus only on integrated solutions may well be left behind.
With new architecture models and disaggregated solutions, along with the increased demand for data and the consolidation of data center operations resulting in fewer and fewer players, the key characteristic to assess in any solution is scalability. In this context, scalability is highly dependent on how vendors support design, deployment, and operation activities.
Intelligence and automation around activities for Day 0, 1, 2, and beyond will differentiate the market between leading vendors and laggards. A highly scalable data center solution can support features such as one-touch deployments, AI-based network troubleshooting and diagnostics, and batch policy configurations.
Finally, today’s application-first mentality positions networks as a support function, reframing our approach from a bottom-up view—network to application—to a top-down view—application to network. Borrowing from the DevOps methodology, the NetOps approach remotely provisions, configures, and determines networking policies to support application performance.
Chris is one of the most brilliant technologists and charismatic speakers I’ve met in a long time. He’s an absolute creative, has a mind focused on solutions, and is driven by a deep belief in what he does. He’s both an inspirational leader and great colleague. I’d work with Chris again any day of the week.
Together we conquered many challenges, won impossible battles in the vendor industry and created a unique security practice. He has an interesting set of talents of being an engineer, innovator, and a thought leader, but never mixes any of these roles. That is what makes him successful as a leader. “Never be comfortable” is what Chris would tell me, which is what pushed me to do my first tech talk. I now have dozens behind me within some of the largest conferences known in the security vendor industry. Chris is nothing short of supernatural.

Chris is always happy to contribute to a discussion or to an issue and is more than happy to lend a hand to both assist team members with their tasks or to lend his expertise in order to benefit the requestor. He is constantly providing knowledge transfer in a peer to peer manner, engaging others to work together to move a project forward or to resolve an issue. Most importantly, Chris is an open and honest communicator about whatever the topic of the moment is, something that is refreshing in today’s world. I could always count of Chris to lend his opinion or his ideas to any subject matter, and this becomes an important contribution for any team. Chris has tremendous talent and is a very hard working, team player. I would welcome Chris to my team at any point in the future.
As Chris’ Editor for Exploring IPv6, a Day One book, he kept to his schedule, output exceedingly lucid prose, and gave a sense of instructional design to an extraordinary tough technology to deploy. On time, better than could be expected, and executed with grace.
I’ve never met anyone who worked as hard as he did at learning and absorbing new skills and technologies and then applying them to his work. He’s a very fast learner and an asset to anyone who has the fortune to work with him.
Chris Grundemann was among the most energetic and competent members of our Council throughout his time as an elected member.
