Our guest today is Martin Casado, General Manager of the Network and Security Business Unit (NSBU) at VMware. He joins the Packet Pushers to get nerdy about where SDN and VMware’s NSX have been, and where they’re going in 2016.
On the business side, VMware announced this past week it has grown the NSX business to a $600 million run rate and tripled the number of paying customers year over year to 1,200. The number of customers running NSX in production has grown 5X, to more than 250.
In this wide-ranging conversation on the transformation of networking, we hit on four main subjects:
- SDN Evolution: We talk about how SDN discussions have moved from trying to understand the concepts to exploring business cases that drive deployment. And as network virtualization has moved into the mainstream, we dive into the relationship between physical and virtual networking.
- Open Source: We talk about the impact of standards bodies and open source software on networking, including projects such as Open vSwitch and the Congress project, which is an effort to translate business requirements into instructions and configurations that can be implemented automatically.
- NSX And ACI: Martin disputes the portrayal of VMware NSX and Cisco ACI as competing products. He notes both products are seeing great adoption, with many customers buying both. We talk about how NSX provides the virtualization layer, and ACI provides a robust network fabric. As both products advance, Martin anticipates that areas of overlap will shrink.
- Distributed Network Services: When you virtualize the network, you can run functions such as firewalls and load balancers out at the edges, and spread the load of those services across multiple CPUs. This enables fine-grained provisioning and resource accounting, and will enable new capabilities and enhance the operational value of network virtualization.
The Packet Pushers have had several discussions with VMware around NSX, network virtualization, security, and containers. Check out these other podcasts:
