2. INTRODUCTION
Business computing stands at a crossroads.
There is no more tolerance for the costly, under-
delivering, grand IT projects of the past.

4. INTRODUCTION
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
deployment.
This presentation proves that cloud and on-premise
systems can work together.

5. INTRODUCTION
We want to lay down some straight-forward advice and steps on how this
can be achieved.
That’s what this presentation delivers.

THE CLOUD

8. 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
and groups.
• 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.

10. WHY CLOUD APPEALS TO YOUR CUSTOMERS
Cloud offers a range of benefits to both large and small enterprises
10 No Cloud is an Island
Large Small
• 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
involve.
• 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.

11. WHY
HYBRID?
No Cloud is an Island11

12. WHY HYBRID?
• 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
application testing.

13. 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

15. ADOPTING A HYBRID CLOUD
Enterprises will pick and choose applications and vendors based on their
business needs, thus creating a diverse and heterogeneous cloud
environment.
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
customer data.

16. CHALLENGES
KNOWN AND NEW
No Cloud is an Island16

17. CHALLENGES KNOWN
Challenge Description
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

18. CHALLENGES NEW

Scalable
Efficient

network
18 No Cloud is an Island

19. CHALLENGES NEW
Challenge Description
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.

20. NETWORK SECURITY
• 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
shutdown VMs.

21. ASSESSING
RETURN ON INVESTMENT
No Cloud is an Island21

22. ASSESSING ROI
 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
