The BUSINESS BENEFITS
11. Agility: It’s easier for your business to respond to changing conditions and new opportunities when you’re in the Cloud.
2. Cost Saving: You can scale down
your IT resources to meet demand, capitalise on automated software updates and pay for your Cloud incrementally.
3. Disaster Recovery: Not only does
Cloud Computing lower the cost of disaster recovery, it can dramatically reduce data recovery time as well.
4. Greener IT: Reduce your energy consumption and carbon footprint of
2
computing by up to 90%.
5. Innovation: Move your IT focus from maintenance to innovation.
6. Mobility: Workers now have the
ability to maintain productivity while away from the office.
7. Multi-tenancy: Share both resources and costs across a large pool of users.
8. Scalability: The Cloud allows for “on demand” provisioning of resources without users having to engineer for peak workloads.
1. Users do no physically possess storage of their own data, which leaves the responsibility and control of data storage with the provider.
2. With data held externally, business continuity and disaster recovery are in the hands of the provider. 3. Data migration complications can arise when
changing cloud provider.
4. And what happens if your cloud provider goes out of business?
5.What happens if your cloud provider goes out of business?

The three types of Cloud
What’s the difference anyway?

PRIVATE CLOUD
A private Cloud is one in which the services and infrastructure are maintained on a private network – generally a local datacenter within an organisation. The clouds offer the greatest level of security and control but you’ll still have to purchase and maintain all the software and
infrastructure, which can significantly reduce cost savings.
Depending on your industry private Clouds do offer some benefits including shared hardware costs, quick recovery from failure and upscaling/downscaling depending on demand. However, the infrastructure will still need to be bought, built, supported and managed.
PUBLIC CLOUD
A public Cloud is one in which the services and infrastructure are provided off-‐site over the Internet. These clouds offer the greatest level of efficiency in shared resources as well as
2
efficiency in cutting spending. However, they are more vulnerable than private Clouds.
Public Cloud as a computing concept offers cheap, commoditised computing resources which outweigh the benefits of in-‐house resources that have limited added value. However, one of the
concerns associated with public clouds is security and reliability. So it’s important to plan security and compliance strategies in advance.
HYBRID CLOUD
A hybrid Cloud offers a variety of public and private options with multiple providers. By using a hybrid approach, you’re able to spread things out over a number of providers to keep each aspect of your business in the most efficient possible environment. The major downside is having to keep track of multiple security platforms and make sure all aspects of your business can communicate with each other.
PRIVATE CLOUD
A Private Cloud is the obvious choice when:
• Data is your business, so security and control are paramount on your list of requirements
• Your company is large enough to run a hyper-‐ scalable datacenter efficiently and effectively on its own.
• Your business is bound to strict security and data privacy issues as well as compliance mandates like PCI-‐DSS and SOX.
PUBLIC CLOUD
A Public Cloud makes sense when:
• You need incremental capacity or the ability to add computer capacity for peak times.
• Your standardised tools and applications are used by many employees.
• You need a sandbox to develop applications across geographical locations.
• You have a SAAS (Software as a Service) application which is offered from a vendor who takes a hard line approach to security.
HYBRID CLOUD
A Hybrid approach is right when:
• Your company uses an SaaS application but has security concernts. Pricate clouds are often used with VPNs, (Virtual Private Networks) for additional security.
• When your market is multiple verticals, you may be in a situation where you want to use private clouds for client interaction, but their sensitive data is kept in a private Cloud. This is an optimal use case for hybrid Clouds.
