MY PERSPECTIVE
3
I try to take the user’s viewpoint
I’m not aligned with a vendor
I believe in industry standards
I’m betting on hybrid cloud solutions
CAVEATS
Please do your research when starting a
cloud project – everything is changing
very quickly!
Service providers (vendors) are anxious
and willing to provide advice – but
buyer beware!!
Try to avoid getting locked into a single
vendor’s products

THE BOTTOM LINE – I.M.H.O.
Cloud computing is here to stay –you need to accept that!
Cloud computing is only now starting to mature
Cloud computing is an opportunity for disruptive change to IT
Cloud computing may require a different approach to projects

“OFFICIAL” ISO CLOUD DEFINITION
Taken from ISO/IEC 17788: Paradigm for enabling network access to a scalable and
elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand. The cloud computing paradigm is composed of key characteristics, cloud computing roles and activities, cloud capabilities types and cloud service categories, cloud deployment models and cloud computing cross cutting aspects.
NOTE – Examples of resources include servers, operating systems, networks, software, applications, and storage equipment.
In practice: Almost anything outsourced has been called a cloud
If it is vendor-provided, it’s a cloud

SO, WHAT IS / ISN’T A CLOUD?
12
Enterprise Cloud Computing
Consumer/Public Cloud computing
STANDARD CHARACTERISTICS (1)
Broad network access: resources are available over
a network and accessed through standard
mechanisms that promote use by heterogeneous
client platforms
On-demand self-service: customers can provision
computing capabilities, as needed, automatically
or with minimal interaction with the provider
Multi-tenancy: physical or virtual resources are
allocated in such a way that multiple tenants and
their computations and data are isolated from and
inaccessible to one another; a tenant is usually a
group of users from a single customer
13
STANDARD CHARACTERISTICS (2)
Measured service: usage can be monitored,
controlled, reported, and billed; customers may
only pay for the resources that they use
Rapid elasticity and scalability: physical or virtual
resources can be rapidly and elastically adjusted,
in some cases automatically, to quickly increase or
decrease resources consumed
Resource pooling: physical or virtual resources can
be aggregated in order to serve one or more
customers; providers can support multi-tenancy
while at the same time using abstraction to mask
the complexity of the process from the customer
14
PUBLIC VS. PRIVATE VS. COMMUNITY
Public Cloud Community Cloud Private cloud
Services available
widely and shared
by many customers
Services available to
a specific set of
customers
Services available to
one customer
Resources controlled
by the provider
Resources controlled
by one or more
members of the
community
Resources controlled
by the customer
Services are provider
managed
Services are provider

Hybrid Cloud = a combination of 2 or more basic clouds
15
“ANYTHING” AS A SERVICE
Infrastructure as a Service
processing, storage or networking services
Platform as a Service
deploy, manage and run customer-created or
customer-acquired applications using one or
more programming languages and one or more
execution environments supported by the cloud
service provider
Software as a Service
Provider supported applications

Infrastructure
(as a Service)
MORE “AS A SERVICE” POSSIBILITIES
Disaster Recovery:
provision & use of remote standby resources
Data Storage:
provision & use of storage & related facilities
Network:
provision & use of transport connectivity & related
network capabilities
Communications:
provision & use of real time interaction &
collaboration
….various other services are also possible

WHY ARE CLOUDS SO POPULAR?
Entrepreneurial – supports new public services (e.g., social networks) require high capacity
Enterprise scope - “systems of engagement” for converged customer access & globalization
Flexible - covers a wide range of ownership, provision, control and deployment alternatives
Cost effective - new revenue source for service providers, and sharing of costs for buyers
Pay-as-you-go – dynamic service provisioning and elasticity reduces capital expenses and inventory costs
Agile and responsive for rapid changes in business, technical and operational requirements
Increased efficiency due to multi-company sharing and continuous technology renewal

BUSINESS CASE FOR CLOUD
Does cloud save money?
Does cloud add capabilities/quality?
Does cloud reduce risk?
Does cloud improve time-to-market?
Does cloud differentiate a business?
Does cloud spawn innovation?
Does the cloud ecosystem exist?
