Hybrid clouds offer new revenue opportunities
By Jelle Frank van der Zwet & Ian Murphy
Business computing stands at a crossroads.
There is no more tolerance for the costly, under-
delivering, grand IT projects of the past.

Companies increasingly look at cloud-based
technologies as a means of delivering the next
generation of IT via a low cost, dynamic and flexible

But not every application will go into the cloud. Core
business-critical systems will stay in-house, while
less sensitive systems are ideal candidates for cloud
This presentation proves that cloud and on-premise
systems can work together.
4 No Cloud is an Island
We want to lay down some straight-forward advice and steps on how this
can be achieved.
That’s what this presentation delivers.

The challenges addressed are:
UNDERSTANDING THE CLOUD
• A world of many clouds
• Cloud deployment models
• Why cloud appeals to your customers
• Better fiscal management
• Adopting a hybrid cloud
THE LOGICAL HOME FOR YOUR CLOUD
• Challenges known
• Challenges new

A WORLD OF MANY CLOUDS
• There are three key cloud models: private, public and hybrid, and market-
focused versions such as community clouds that address specific markets
• A private cloud is where the resources are owned and accessed only by the
enterprise, whereas the public cloud is a shared environment.
• For some applications and organisations, there is a solid business case
where core applications will be in a private cloud but some applications and
functions exist in the public cloud.
• This is known as the hybrid cloud.

WHY CLOUD APPEALS TO YOUR CUSTOMERS
Cloud offers a range of benefits to both large and small enterprises
10 No Cloud is an Island
• Efficiency: ability to manage budgets, IT
maintenance and upgrade programmes more
efficiently. This is because cloud computing
offers flexible access to IT resources, skills,
new technologies and the latest updates and
patches for servers, tools and applications.
All this without the management, licensing and
purchasing headache this would normally
• New Access: cloud computing levels the
technology playing field. Access to resources
and technologies beyond anything their usual
budgets could afford enables them to take their
business to the next level.
Importantly, they gain access to the people and
processes that can help create competitive
advantage from these new technologies.
• The key challenges for all sizes of business are creating the private cloud
and then integrating it with their chosen public cloud.
• Correctly configured, the hybrid cloud offers many benefits. Improved
SLAs, the ability to scale an application out to hundreds of servers, the
ability to do very specific types of computing, such as big data or

BETTER FISCAL MANAGEMENT
The most important benefit of hybrid cloud is cost reduction and better fiscal
management of IT. This benefit can be realized in several ways:
• Reduced capital expenditure on new hardware and software
• Reduced running costs on data centre power and cooling
• Higher utilisation of resources which in turn lowers the cost of providing IT
• Metering which allows application usage to be more effectively costed
• Faster and more cost-effective access to new applications through
Software as a Service (SaaS)
• Ability to deploy new solutions more quickly

ADOPTING A HYBRID CLOUD
Enterprises will pick and choose applications and vendors based on their
business needs, thus creating a diverse and heterogeneous cloud
Examples of hybrid cloud adoption today are:
• Corporate websites are moving to the public cloud to improve access and
reduce the risk of downtime.
• Online web stores are using the public cloud for their catalogue and
transferring customers to the private cloud to complete payment options.
The public cloud allows for the quick provisioning of resources when a
promotion takes place while the private cloud enables the securing of

Infrastructure and Virtualisation Hardware is increasingly power-efficient. Although prices have
fallen, it can still be expensive. The recession has seen a large
amount of hardware, often less than 3 years old, on the quality
second hand market
Software and Services The challenge is creating an automated and controlled
environment with proper management and governance tools
Security You may be sharing hardware and even services across multiple
clients, so there is a need to ensure the physical and logical
designs are secure
The importance of partners Choosing the right partner is important because they will have
lease programmes for hardware and software and will work with
you on resolving issues such as software licensing

Fast Cloud-based solutions can take advantage of very high speed interconnects
that would be very expensive to provision direct to a company office.
Dedicated Direct links between the cloud and the customer guarantees performance, and
improves security by removing the public Internet risk
Scalable All applications have traffic peaks which can sometimes be managed through
the Quality of Service mechanisms.
Efficient QoS and traffic shaping help manage network traffic - important for mission-
critical applications that need guaranteed bandwidth at busy times.
Resilient Multiple network circuits into both the data centre and the customer provide
scalability and business continuity.

• Traditional solutions rely on firewalls for protection.
• Recognising the speed with which VMs are created and deployed, vendors
have created rule-based virtual firewalls that can be kept constantly
updated and deployed on demand.
• The key here is ‘constantly updated’. Now, there are vendors that allow for
a master firewall to update the elements of all firewalls, even those in

RETURN ON INVESTMENT

The real ROI for cloud is about the costs that it would take to deliver the
same level of service internally.
This includes hard and soft metrics such as uptime, user experience, cost
of hardware / software, integration, cost of bandwidth, data centre power
and cooling costs, and staff costs
