OpenStack is an open-source framework for a cloud computing operating system.
Arista plans to also demonstrate integration with Big Switch's controller through OpenFlow. Ostensibly, all three of these controllers would be able to program Arista switches through three different APIs and protocols.
Arista has a four-legged strategy for cloud SDNs:
• Multi-path leaf-spine networking for scale, using EOS and Layer 2/3 standards like MLAG, ECMP and TRILL.
• Distributed cloud control with EOS features such as Zero-Touch Provisioning, Latency Analyzer and Advanced Event Management.
• Network-wide virtualization with discovery and segmentation of VMs, and VXLAN.
• Single point management using APIs like OpenFlow, OpenStack and those in Arista's CloudVision software.
