The evolution of cloud requires not only virtualised server resources but also on demand, utility consumption of physical hardware resources delivered in real time.
5. Hybrid Clouds Are Delivering Real Results Today
“We achieved four times the efficiency
for half the cost. You can do the math.”
Jim O’Neill, CIO

“Rackspace hosted applications will include the
public-facing ecommerce site www.dominos.co.uk,
as well as the online payment gateway, corporate
email and back-office systems, and the company
intranet linked through RackConnect®.”
Colin Reed, IT Director
“For us, a hybrid cloud is the best of both worlds. It
delivers on its promise of improved performance and
scalability of the cloud while empowering us to keep our
high-performance apps that need to scale vertically on
managed hardware.”
Matt McClure, Vice President, Chief Architect

It’s a Nice Neighbourhood…

• Networks & physical machines shared with other tenants, can’t rely on
consistency of performance in network, storage and compute.
• Response time of each node is not constant, it is a range of values, often
measured experimentally - Markovian
• Some nodes become unavailable/unresponsive, your model breaks
• Overall response time becomes dependent on probability equations

RACKSPACE® HOSTING | WWW.RACKSPACE.COM.HK
Why this matters
10
• Accessed via API, like public cloud.
• Utility service, charged by the minute -
much simpler and more powerful than
VMs/public cloud.
• Built on OpenStack software and Open
Compute hardware. The API for OnMetal
is the OpenStack Nova API. It’s familiar to
users of any OpenStack public cloud.
Users don’t have to worry about vendor
lock-in.
• OnMetal servers are customized for
specific workloads.
• No hypervisor, and no virtualization tax.
• No sharing of metal with any other user.
• All solid-state, no moving parts. Less heat +
Less vibration = higher MTBF.
• Optimized for specific workloads. We have
servers customized for databases, for low-latency
caching, and for handling web
requests. Our database server, for example,
offers 3.2TB of PCIe flash storage, 128GB of
RAM, and more than 200,000 IOPS.
• Specializing the gear not only boosts
performance but helps keep costs under
control.
• We believe the network should have
consistently low latency. OnMetal cabinets
use 10-gigabit networking and minimal
network over-provisioning.

Notes de l'éditeur
Hubspot is a marketing company that migrated a lot of their infrastructure to Rackspace based on OpenStack and the ability to have a consistent, open, integrated environment, and in doing so, they improved efficiency by 4x and cut their costs in half.
Dominos are a key case study in the UK – a full case study will follow
Map My Fitness is a startup in Austin that is finding Hybrid cloud gives them the right model to grow based on what elements of their application needs quick scalability and which ones need high-performance stable environments.
