INTRODUCTION

Business computing stands at a crossroads.

There is no more tolerance for the costly, under- delivering, grand IT projects of the past.

2 No Cloud is an Island

INTRODUCTION

Companies increasingly look at cloud-based technologies as a means of delivering the next

generation of IT via a low cost, dynamic and flexible resource platform.


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.


INTRODUCTION

We want to lay down some straight-forward advice and steps on how this can be achieved.

That’s what this presentation delivers.

UNDERSTANDINGTHE CLOUD

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.


CLOUD DEPLOYMENT MODELS


WHY CLOUD APPEALS TO YOUR CUSTOMERS

Cloud offers a range of benefits to both large and small enterprises


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.


WHYHYBRID?

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.


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


WHY HYBRID?


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.



CHALLENGES KNOWN AND NEW

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


CHALLENGES NEW

Cloud infrastructure requires a

FastDedicatedScalableEfficientResilient

network


CHALLENGES NEWChallenge 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.


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.

INVESTMENT

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


ASSESSING ROI


Business Case Cloud Premium

Reducing the cost of development and testing environments

• The speed with which a testing environment can be provisioned• Ability to do more intensive and extensive testing of

applications• Access to high value test tools on demand via SaaS• Access to test professionals in different locations

Scalability • Ease of adding additional compute, network and/or storage resources

• Ability to shrink resource pool when not required

Competitive advantage • Faster time-to-market for new applications and solutions means new market opportunities can be quickly explored

• Speed of identification of trends and designing competitive solutions

• Lower cost of IT releasing more money for other parts of the business
