The Arista Advantage
The world is moving to the cloud to achieve better agility and economy, following the lead of the cloud titans who have redefined the economics of application delivery during the last decade. Arista’s innovations in cloud networking are making this possible. New, modern applications such as social media and Big Data, new architectures such as dense server virtualization and IP Storage, and the imperative of mobile access to all applications have placed enormous demands on the network infrastructure in data centers.
Applications have been decomposed into multiple tiers of interoperable subsystems leveraging new standards. These applications are deployed in scalable pods or clusters that make scaling and supporting them easier.
Traffic patterns that once centered on the use of lightly utilized links in and out of the data center (north-south) for mainframe and client-server applications such as email have been supplanted by highly distributed applications that drive heavily utilized links for server-to-server and server-to-storage (east-west) traffic within the data center.
Data centers that once consisted of hundreds of servers are now built on a scale of more than 100,000 physical servers and more than one million Virtual Machines (VMs) or Containers.
Availability requirements for the new data center network are also higher -- now 24x7x365 -- with no time for maintenance windows or planned downtime.
