Arista Integrates EOS With OpenStack in SDN Push
The networking vendor, which also is adding OpenFlow extensions to the OS, is looking to improve network programmability in cloud environments.Arista Networks officials are integrating the company's network operating system with the open-source OpenStack cloud technology and bringing enhanced OpenFlow extensions to the OS, the latest steps in the vendor's efforts in software-defined networking. The new capabilities are available in the latest release of Arista's Extensible Operating System (EOS) and address demands from businesses and service providers for greater network programmability and flexibility in public and private cloud computing environments, according to company officials. The improved networking capabilities in the cloud mean faster cloud provisioning, enabling IT workflows that normally take weeks to be done in seconds. "Extending Arista EOS for connection to cloud orchestration platforms provides programmability for building agile, self-service cloud architectures," Tom Black, vice president of software-defined networking (SDN) engineering for Arista, said in a statement. "This has been core to Arista EOS development from its inception." SDN is getting a lot of attention from enterprises and service providers alike. The technology promises to create more flexible, scalable and programmable networks by essentially taking network intelligence out of the hardware—such as switches and routers—and putting it into software-based controller platforms. The rush to SDN is coming, not only from established network vendors like Cisco Systems, Hewlett-Packard, Juniper Networks and Dell, but also such startups as Big Switch Networks, Embrane and Plexxi. VMware, Oracle and others also are adding SDN capabilities through acquisitions to broaden their larger data center portfolios.
Arista officials have said that while decoupling the data and control planes (with a controller to communicate between the two) has been the basis for such SDN tools as the OpenFlow protocol, companies like theirs and VMware—which bought SDN pioneer Nicira last year—are expanding on the SDN promise with the increased capabilities within EOS, such as the API integration into the OpenStack open-source cloud platform.
