Yahoo Japan Deploys an
OpenStack-based Private Cloud for
Service Developers with Brocade
Yahoo Japan Corporation (Yahoo) is an
information technology provider that
operates Japan’s largest portal site, Yahoo!
Japan. Yahoo! Japan offers a variety of
online services including a search engine,
auctions, news, weather reports, sports
news, e-mail, and shopping.
Yahoo had already built a private cloud
environment that enabled them to deliver
services including compute, storage, and
networks in the early days of its networkbuilding history. But it was configured to
heavily depend on hardware and Yahoo
began facing challenges that included
limited flexibility, inefficient resource
utilization, and poor price-performance.
To address these issues, Yahoo planned
to eliminate hardware dependence by
abstracting the hardware, including
compute, storage, and networks, in order
to maintain the optimal data center
hardware life cycle. In order to abstract the
hardware, Yahoo decided to deploy a cloud
infrastructure using OpenStack software,
as it is becoming increasingly prominent
and driving robust innovation with its
open-source characteristics.

The Brocade OpenStack Plug-in, for the
Brocade VDX product family, was codeveloped by Yahoo and Brocade to deliver
virtual network services and FWaaS without
sacrificing performance. Yahoo determined
that it was able to achieve throughput that
was eight times faster with half the latency,
compared to software-based GRE (Generic
Routing Encapsulation) tunneling.

“OpenStack is rapidly gaining adoption,
doubling every six months and giving
us peace of mind because it is actively
deployed by various enterprises and
organizations. It is also highly open
and abundant and the strong development
team is helping to make it a networking
standard. We saw more and more hardware
supporting OpenStack in the market
and concluded that OpenStack was the
quickest way to abstract hardware,” said

DELIVERING VIRTUAL NETWORK
AND FWAAS WITHOUT SACRIFICING
PERFORMANCE
Engaged in designing a cloud infrastructure
based on OpenStack, Yahoo began searching
for a vendor that would be able co-create
the infrastructure with them. Yahoo chose
Brocade for its proven track record as a key
solution component of its large-scale Apache
Hadoop-based infrastrucuture, as well as
its corporate-wide commitment to open
technologies. In Yahoo’s OpenStack-based
infrastructure, Brocade® MLXe® Routers for
core switches underpin a higher layer
of the data center network and Brocade VDX®
Switches are deployed at the aggregation
layer to converge racks and Top-of-Rack
(ToR) switches.
Brocade VCS® Fabric technology underpins
the deployment with several enhancements
to the OpenStack plug-in, providing significant
fabric advantages. These include Firewall-asa-Service (FWaaS), Switch Virtual Interface
(SVI), VRRP Support, and logic-based
resiliency improvements during cluster
formation. Additionally, the deployment took
full advantage of VCS Fabric technology
by deploying it as a single fabric with the
Brocade VDX 8770 used in the aggregation
layer for significant scalability.
“In the world of OpenStack, it is common
to abstract Layer 2 network services with
a software-based tunneling model. If it’s
fully software-based, however, network
performance would greatly deteriorate and
monitoring and troubleshooting become
complicated due to an increased amount of
layers that need to be managed. If we can
directly control the Brocade VDX Switch’s
virtual network capability with the integrated
multitenancy support delivered with Brocade
VCS Virtual Fabrics, we can gain enhanced
flexibility brought by software-based control,
while obtaining the network performance
equivalent to hardware-based models,” said
Takuya Ito, Senior Manager, Site Operations
Division, Yahoo Japan Corporation.
DELIVERING LBAAS WITH AN
OPENSTACK PLUG-IN
by implementing LBaaS. When the Neutron
plug-in that can control the Brocade ADX
Switch became available, we worked together
with Brocade to develop the plug-in from
scratch,” said Rui Takagi, Infrastructure
Engineer, Site Operations Division, Yahoo
Japan Corporation.
Yahoo also deployed the Brocade ADX®
Application Delivery Switch load balancer
to manage and load balance virtual
servers running on the OpenStack-based
infrastructure. The Brocade ADX Switch
was installed to directly connect with the
Brocade MLXe. Yahoo uses the Brocade ADX
Switch for load-balancing, but it required
manual operations that burdened network
administrators. Therefore, when building
the OpenStack-based infrastructure, the
company sought to operate with LBaaS,
which is free from performance degradation
because of the load-balancing capability
abstracted with the Brocade Neutron plug-in.
Yahoo started collaborating with Brocade in
the spring of 2013, co-developing plug-ins
together with the Brocade development team.
The two companies released functions one
after another, developing plug-ins for LBaaS
and FWaaS over a year and a half.
SIMPLIFYING NETWORK OPERATIONS
WITH THE OPENSTACK-BASED
INFRASTRUCTURE
“Since we operate many and diverse
services, we have over 100 requests a
day for changing the configuration of the
load balancer and firewall used for each
service. Considering that our system will
expand further with the OpenStack-based
infrastructure, we will not be able to handle
the tasks manually any longer. That’s why we
sought to eliminate performance degradation
Yahoo will continue to expand the OpenStackbased infrastructure by adding an average of
5,000 virtual servers a month. Additionally,
the company is expected to scale to provide
100,000 virtual servers in 2015, anticipating
significantly simplified network operations,
through the use of virtual network services
with Brocade products, LBaaS, and FWaaS.

“Our own business need triggered the
co-development of the plug-ins for the
Brocade VDX Switch and Brocade ADX
Switch, which will be distributed to other
users by Brocade. The world of opensource should be created, used, and
advanced by everyone. Brocade shared
this vision with us and supported the
development of the plug-ins. We are
deploying our business under a mission
of ‘Creating excitement with global
standards.’ This project was a good
example of that, through jointly creating
an infrastructure with Brocade by using a
global standard, OpenStack.”
