Agenda
A walk through the Cloud Business Notation ideas
and concepts - 30 minutes - by Mark Skilton
A discuss on the ideas and concepts presented - all
Identify advantages and any concerns that need to
be addressed - all
Identify ideas on how the Cloud Notation may fit with
other architecture models - the intention is to work
with other stack type models such as NIST, TOGAF
for example - to generate different views of cloud
models for different types of stakeholders , both
technical and business oriented.
Introduction
The following notes and diagrams are from
the meeting attended by a range of
participants at the Cloudcamp Boston July 21
The objective was to identify ideas and
approaches to define a Cloud Computing
Reference Architecture that better defined
and represented the evolving nature of the
Cloud and how it could be provided and used.
Scope of what I’m focusing on..
I am just looking at one model view of Cloud
Architecture for business users.

Why do we need a Cloud Computing
Reference Architecture CCRA?
A range of comments included:
Current reference models are from a seller perspective and don’t fit how cloud “feels” from a
User perspective
SOA and Web 2.0 have provided foundation message and payload standards but need to
move to into describing how the service “looks and feels”
Historically the “tiers” approach to describing architecture has originated from the Client-server
era; examples seen in 4+1, Zachmann and other concepts have resulted in a perspective of a
Provider oriented style “tiers” in Cloud which has limitations
Syntax and semantics have been focused on by community and industry forums but other
aspects of behavior interoperability and choreography modelling that could help describe cloud
and cloud services is potentially a gap a present
There are many discussions and standards forums on interoperability in the industry but little
methodology evolving from an overview of how different parties might work across a cloud
service
There are Industry efforts to extend SOA and security standards but these come from a pre-
existing viewpoint rather than a clean start on cloud descriptions
We are seeing academic research and evidence in Grid computing, agent based technology
and some vendors providing examples of how to visualize and potentially represent cloud
services more closely relating to the cloud experience. The nature of cloud is emerging
continually and the CCRA could help narrate aspects of requirements and how to use Cloud
The need for a meaningful Cloud Computing
Reference Architecture Methodology
We need to have a methodology that recognizes better how
cloud computing experience “looks and feels like in the real
world”
Considering an analogy; we have seen examples such as virtual
reality VR software standards that has attempted to represented
a more realistic software representation of the real world – the
point is not the VR but that the aim is to create a language and
approach that represents how business and technology are
working together. Cloud computing is yet another environment
/ ecosystem combination of tools , assets, people, businesses
and experiences that represent aspects of cloud
The current Provider oriented Cloud
Computing reference models
While NIST is arguably the most well known
http://csrc.nist.gov/groups/SNS/cloud-computing/cloud-computing-
v26.ppt , there are many examples of equally significant and influential
models including the Cloud Computing taxonomy from the Google
hosted Cloud Computing Use cases Group
http://www.scribd.com/doc/18172802/Cloud-Computing-Use-Cases-
Whitepaper and the “Towards a unified Ontology of Cloud Computing”
by Lamia Youseff, University of California, Santa Barbara and Maria
Butrico and Dilma Da Silva of IBM T.J. Watson Research Center
YorkTown, New York http://freedomhui.com/wp-
content/uploads/2010/03/CloudOntology.pdf .
All these examples also provide a technology tiered framework of
implementation viewpoints for cloud computing.
Building advocacy for a Business
User prospective of Cloud Computing
But, this has been predominantly from a provider viewpoint of
cloud computing and less on how the consumer might see,
experience or use the cloud service. These conceptual
frameworks represent a description of a technology tiered
architecture most meaningful to Enterprise technologies. While
this is important it prevents a separation of the concerns most
important from the consumer perspective of the service.
The customer experience and the business user viewpoint of
cloud is quite different from the discussions of design and run
time choices for cloud services.
A critical goal of cloud computing is to move towards a user on-
demand perspective, to use the “cloud” as a service for
business.

Balancing the Buyer and Seller
perspective
We are not advocating a different cloud
computing model but a set of models that
take into account both the consumer and
provider side , the buyer and seller and other
intermediate roles that support the types of
homogeneous and heterogeneous platforms
and subclasses of data and user devices that
are found in the real world of IT.
5 key Business Benefits of a User
driven Cloud viewpoint
Defining a clear Cloud Computing
Architecture Modelling approach will help
further develop Cloud Computing adoption
Defining a common set of standard
terminology is key to any new emerging
technology trend in helping to raise
awareness and express requirements of that
technology.
5 key Business Benefits of a User
driven Cloud viewpoint
Monetizing cloud services
It is currently an area of adoption question; “how much do cloud services cost my business?”. Defining a
way to show individual services and their common shared service or incremental growth could help
accelerate an adoption profile where users understand the cost of service better.
Visualizing the real cloud
Cloud is already here, we everyday see the email, video feeds, web sites and tweets. Business needs a way
of describing this from that perspective so that we can accelerate the meaning full integration and adoption
of cloud into everyday experience.
Defining a clear Customer experience
Probably the biggest affect on everyday lives has been the attention span and impact on people and
business through on-demand and real-time exchange of messages and content enabled by an increasing
social and dynamic network of services that can be described as “the cloud”. Showing this experience and
how this changes in a “mash-up”, on-demand world would greatly improve the real world representation of
consumer choice , the self-service “menus” and “portfolios” open to business.
Describing who has ownership of Security Risk in the cloud
The greatest impediment to cloud is probably the risk and security aspects of the data, location and control
of services. Defining a user location perspective of security protection points would greatly enhance the
provider conditions to address those critical concerns.
Defining how to monitoring Quality of Service QoS in the cloud
Overall how the service level performance monitoring and disaster recovery aspects of the cloud service
needs to be shown in a heterogeneous context. Many enterprise level SLAs need OLAs that are
representative of business level QoS standards, how multiple service monitoring and management systems
need to be position on the provider side and the consumers side. A methodology that helps clarify this
“ownership of responsibility” would be a great benefit in definition a clear boundary of service trading and
exchange.
Why this helps monetize Cloud
Because it is a middle-out not a outward-in
approach – it drives the user journey through
using the cloud
You look at cloud from the viewpoint of using
one to many cloud services which can be
used and built on incrementally. This matches
the incremental cashflow and elastic growth
we so often see in cloud service use
Defining Models for Cloud
Computing that considered the
Business User viewpoint
At Cloudcamp we discussed…
What a Cloud Computing Reference
Architecture CCRA might contain ?
Cloud Computing Technology reference model
This is arguably already covered in the many technology stack reference models: NIST etal. They provide a provider
technology perspective of the cloud solution
Cloud services model
A description of the types of services we see in cloud computing – more from the perspective of the type of
“operations” and services that cloud might support. Examples. This is not Web services or BPEL style
protocols and workflow styles
How the service meta data might be defined
Cloud Actor Model
The types if actors that might participate in a cloud service from all perspectives
Cloud network (Choreography) Model
How the overall flow of a Cloud service transaction might flow
How the cloud service “communities” might look and interact
How trading and marketplaces might interoperate
Integrated Cloud Framework
How to design Cloud Components
How to define a Cloud Service Lifecycle
Cloud catalog and user experience model
How a catalog or catalogs of business and IT services might be represented in the cloud
How the services might be visualized , discovered and used
Cloud Meta data and Behavior (Cloud Contract) Model
A description of the service exchange meta data model
Others……..
Some of these relate to CCA, SOCCI etc

Nasdaq http://www.nasdaqomx.com/
Nasdaq OMX has lots of stock and fund data, and it wanted to make
extra revenue selling historic data for those stocks
and funds. But for this offering, called Market Replay, the company
didn't want to worry about optimizing its databases and
NASDAQ OMX servers to handle the new load. So it turned to Amazon's S3 service to
host the data, and created a lightweight reader app using
Adobe's AIR technology that let users pull in the required data.

The Adobe AIR app Courbois' NASDAQ OMX
team put together in just a
couple days pulls in the flat files
stored at Amazon.com and then
creates the replay animations
from them. The result: "We
don't need a database Lightweight reader
constantly staging data on the app using Adobe’s
server side. And the price is AIR
right."

The New York Times also used S3 for a data-intensive project:
converting 11 million articles published from the
newspaper's founding in 1851 through 1989, to make them
New York Times available through its Web site search engine. The Times
scanned in the stories, cut up into columns to fit in the scanners
(as TIFF files), then uploaded those to S3

Environment
Amazon played a key role in the development of cloud computing by
modernizing their data centers after the dot-com bubble, which, like most
computer networks, were using as little as 10% of their capacity at any one
time just to leave room for occasional spikes. Having found that the new
Amazon AWS cloud architecture resulted in significant internal efficiency improvements
whereby small, fast-moving "two-pizza teams" could add new features faster
and easier, Amazon started providing access to their systems through
Amazon Web Services on a utility computing basis in 2005.

Is this notation something that The Open Group Cloud
Work Group think has merit and should be carried
forward ?
Should this be a set up as a separate Project within the
Cloud Work Group with new chairs and a Charter ?
Should this be kept within the current CBA Project as it
has links with the metadata work in CBA ?
How should this be linked with the CCA and SOCCI
project teams - the intention is to position CBAN as
separate to other projects and to be business oriented
