THE ANSWER? HYBRID CLOUD
Definition: an application or workload that incorporates
cloud with other platforms


NO MORE TRADE-OFFs


SECURITY BENEFITS OF HYBRID CLOUDS

Compliance requirements?
Keep confidential data on dedicated storage and DB
Add cloud for public portions of site (images, public content, leverage CDN)
Need better security?
Add a dedicated FW, IDS, DDoS prevention to a cloud backend
VPN to encrypt site-to-site traffic
Need to know where your data is?
Keep your customer data on-site, bridge to cloud for processing
Data Protection Act
Need to ensure Business Continuity or Data Security?
Enterprise storage for data replication, cloud for compute
Block based encryption and other data security tools still work better on traditional
gear


TIMING BENEFITS OF HYBRID CLOUDS (AGILITY)

No time or budget to rewrite your entire app?
Move a piece to the cloud (web tier, batch process, test/QA environment)
Gets you using cloud sooner, get some of the benefits sooner (cost reductions,
flexibility)

Dedicated for average loads, spike into the cloud
Scale horizontally, add a lot of capacity quickly
Only pay for the peak during loads
Time to market
Reduce dev time , faster QA testing
Improve speed to market, make $$$ sooner on your new app
Save on admin costs
Dev Ops developers can program the system management tasks now, you can do
more job sharing

AN EXAMPLE OF HYBRID CLOUD FROM RACKSPACE

gives you the freedom to choose the best platform for
your applications by unifying the breadth of the Rackspace portfolio into a
single solution.

Combine traditional and cloud hosting - put workloads where they
perform best
Centrally define Network Security Policies - automatically applied to
your entire configuration
Add the security of a dedicated firewall to your cloud configuration
Securely move workloads between your data center and Rackspace
over an encrypted VPN tunnel or private link


GROWING A BUSINESS USING HYBRID CLOUD
Day 1
Situation: startup business
Problem: no funding
Solution: Cloud Servers


Day 2
Situation: launching first product
Problem: needs security
Solution: add a firewall


Day 3
Situation: rapid growth
Problem: database slowing down
Solution: move DB to physical server cluster


Day 4
Situation: seasonal traffic
Problem: big spikes
Solution: load balance cloud and physical servers


Day 5
Situation: app growing complex
Problem: need secure flexibility and fast storage
Solution: add Private Cloud and SAN storage


Day 6
Situation: very busy site
Problem: constantly adding and removing servers
Solution: Rightscale Server Templates and AutoScaling

+


Problem:
Large online events with unpredictable spikes up to
15X normal traffic load

Rackspace Solution:
Run high I/O Database on Dedicated Servers, bursting
CPU intensive application servers into the Cloud

TECHNICAL BENEFITS OF HYBRID CLOUDS
Public Cloud + Hosted
Cloud: utility price, deploy in seconds, expand rapidly = agile
Dedicated: customizable, performance, security, compliant,
feature/product rich, familiar/comfortable
Public Cloud + Private Cloud
Internal IT as a service provider + more capacity in public
Single tenant + multitenant
Portability of images = test/dev in public, promote to prod in private
My DC + cloud DC
Keep my customer data here, use cloud for public workloads
Out of space? Bolt on a cloud
Need to park your data while you refresh? Rent some storage
DR on the cheap? Try a cloud


RACKCONNECT DESCRIPTION
RackConnect is a unique solution designed for customers who require the flexibility and elasticity of
the cloud, as well as the enhanced security and performance characteristics of traditional hosting the
best of both worlds. In essence, RackConnect enables customers to realize the power of Hybrid
Hosting.

For Enterprises:
Enterprises trust their mission critical applications on highly available and high performing
traditional hosted infrastructure, using products such as high speed SAN storage, single tenant
virtualization and high capacity load balancers. RackConnect can enhance this infrastructure with
rapidly elastic cloud compute and storage resources, allowing you to flex your capacity at a

For Small and Midsized companies:
Customers with smaller dedicated hosting footprints can realize cost savings by shifting certain
components of their application to a cloud platform, such as the web or application tier. Moving
image libraries to cloud storage, for example, reduces the dedicated storage requirements and
allows faster content distribution via the CDN capability of Cloud Files.
For customers using Cloud Servers, RackConnect can allow you to add in a custom-built, high
performance database or app server to provide a more secure, single tenant backend for your
app. Or layer on a dedicated firewall, Web App Firewall, or DDoS mitigation to help protect your
entire solution.


How RackConnect Works
Choose an F5® BIG-IP® Local Traffic Manager or any Cisco® ASA firewall to connect your
traditional hosted infrastructure to the Rackspace Cloud
Cloud Servers can be automatically added to your load balancer, enabling you to scale on
demand
Connect to Rackspace with an encrypted VPN tunnel, turning the Rackspace Cloud into an
extension of your datacenter or existing IT infrastructure
Add Cloud Files for easily scalable storage


DEDICATED FIREWALL FOR CLOUD SERVER

Add the security of a dedicated physical firewall to your Cloud Servers
environment.

Suitable Use Cases
