KT Cloud Performance Exceeds that of Amazon, GoGrid, Rackspace

CloudHarmony Benchmarking Validates Architecture Used by KT and Cloudscaling

SAN FRANCISCO, October 14, 2010 - A performance benchmark report released today
(blog.cloudharmony.com/2010/10/cloudscaling-kt-private-cloud.html)
shows how telecom operators can build clouds that deliver the same
high-performance and cost-effectiveness that the market has come to expect
from well-known public clouds.

The benchmarking, conducted by CloudHarmony and commissioned by
Cloudscaling, compares the performance of KT's recently launched private
cloud against the performance of five large public clouds offered by Amazon,
BlueLock, GoGrid, Rackspace and Terremark. KT's private cloud scored at or
near the top in each category, including CPU, disk and memory performance.
Simulations included database, application and web servers under a variety of
loading conditions.

The cost and performance characteristics of the best-known public clouds
are driven largely by their use of commodity hardware and open-source
software stacks, coupled with highly automated system management that reduces
operating costs. Instead of taking this approach, most organizations have
built clouds using the enterprise-class architectures and tools familiar to
them. Those architectures are, however, far less cost competitive when
applied to cloud computing.

"The benchmarking report gives us confidence that our philosophy of cloud
design is a correct one," said Jung-sik Suh, senior vice president of the
Cloud Business Service Unit at KT. "We are looking forward to realizing this
performance in a real-world setting as our organization begins using the
private cloud for internal projects."

"Few companies have figured out how to deliver reliable, high-performance
cloud computing services at low cost," said Randy Bias, founder and CEO of
Cloudscaling. "The technical challenges were formidable, but we partnered
with KT to deploy clouds that follow the best practices of the public-cloud
market leaders. CloudHarmony's work for the first time offers validation of
this architecture as a model for telcos and service providers."

KT is Korea's largest fixed-line operator and second largest mobile
carrier. The company has launched their private cloud as the first milestone
in using cloud computing as a platform to provide a variety of data-intensive
services to devices such as smart phones and tablet PCs as well as to deliver
computing infrastructure internally to their enterprise.
