Definition of “Cloud Computing”
• According to NIST:
“Cloud Computing is a model for enabling
ubiquitous, convenient, on-demand network
access to a shared pool of configurable
computing resources (e.g., networks, servers,
storage, applications, and services) that can be
rapidly provisioned and released with minimal
management effort or service provider
interaction. This cloud model promotes
availability and is composed of five essential
characteristics, three service models, and four
deployment models.”

Cloud Essential Characteristics
(NIST)
•
On-demand self-service.
–
•
Broad network access.
–
•
The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with
different physical and virtual resources dynamically assigned and reassigned according to consumer
demand. There is a sense of location independence in that the customer generally has no control or
knowledge over the exact location of the provided resources but may be able to specify location at a higher
level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing,
memory, network bandwidth, and virtual machines.
Rapid elasticity.
–
•
Capabilities are available over the network and accessed through standard mechanisms that promote use
by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling.
–
•
A consumer can unilaterally provision computing capabilities, such as server time and network storage, as
needed automatically without requiring human interaction with each service’s provider.
Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out, and
rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear
to be unlimited and can be purchased in any quantity at any time.
Measured Service.
–
Cloud systems automatically control and optimize resource use by leveraging a metering capability1 at some
level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user
accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the
provider and consumer of the utilized service.

Service Models (NIST)
• Cloud Software as a Service (SaaS)
– The capability provided to the consumer is to use the provider’s
applications running on a cloud infrastructure.
• Cloud Platform as a Service (PaaS)
– The capability provided to the consumer is to deploy onto the
cloud infrastructure consumer-created or acquired applications
created using programming languages and tools supported by
the provider
• Cloud Infrastructure as a Service (IaaS)
– The capability provided to the consumer is to provision
processing, storage, networks, and other fundamental computing
resources where the consumer is able to deploy and run
arbitrary software, which can include operating systems and
applications.

Cloud Software as a Service
(SaaS) / NIST
• Cloud Software as a Service (SaaS)
– The applications are accessible from various client
devices through a thin client interface such as a web
browser (e.g., web-based email).
– The consumer does not manage or control the
underlying cloud infrastructure including network,
servers, operating systems, storage, or even
individual application capabilities, with the possible
exception of limited user-specific application
configuration settings.

Cloud Platform as a Service (PaaS)
/ NIST
• The consumer does not manage or control
the underlying cloud infrastructure
including network, servers, operating
systems, or storage, but has control over
the deployed applications and possibly
application hosting environment
configurations.

Cloud Infrastructure as a Service
(IaaS) / NIST
• The consumer does not manage or control
the underlying cloud infrastructure but has
control over operating systems, storage,
deployed applications, and possibly limited
control of select networking components
(e.g., host firewalls).

Deployment Models (NIST)
•
Private cloud.
– The cloud infrastructure is operated solely for an organization. It may be
managed by the organization or a third party and may exist on premise or off
premise.
•
Community cloud.
– The cloud infrastructure is shared by several organizations and supports a
specific community that has shared concerns (e.g., mission, security
requirements, policy, and compliance considerations). It may be managed by the
organizations or a third party and may exist on premise or off premise.
•
Public cloud.
– The cloud infrastructure is made available to the general public or a large
industry group and is owned by an organization selling cloud services.
•
Hybrid cloud.
– The cloud infrastructure is a composition of two or more clouds (private,
community, or public) that remain unique entities but are bound together by
standardized or proprietary technology that enables data and application
portability (e.g., cloud bursting for load balancing between clouds).

Enabling Mobile Cloud
• Mobile Cloud
– It enables the cloud services to be ubiquitously
available across multiple, separate mobile network
operator domains
– Mobile Cloud Providers (MCP) are the
“intermediaries” facilitating the implementation of a
Mobile Cloud through agreements with individual
network operators (based upon wholesale models)
– By using a MCP the Service Providers (SPs) can
have a single interface and single business
relationship, but interwork with multiple network
operators

Inter-Cloud?
• It is a concept based on the aggregation of
deployed clouds
• From a service user's perspective, we can look
at the Inter-Cloud as an on-demand environment
where various services controlled by other
organizations can be leveraged and composed.
•  Services that are outside of an organization's
own boundaries, operated and controlled by
other organizations can become part of the
aggregated portfolio of services of that
organization

Mobile Clouds Examples relevant
to 3GPP
• GSMA’s OneAPI’s objective is to provide a
cross-operator domains framework for
Mobile Cloud Computing
• Based upon OneAPI, the GSMA is acting
as a Mobile Cloud Provider/Aggregator,
providing SPs access to network
resources and charging capabilities (NaaS
type of cloud) of multiple mobile operators

Cloud Legal Aspects
• It is to be expected that many cloud computing
scenarios will span the laws of multiple
jurisdictions.
• The laws at the users’ location, at the location of
the cloud provider, etc, may all potentially apply.
• The same data may be stored in multiple
jurisdictions at the same time and the actual
location of a user’s data may be difficult to
determine

Recommendations on Specific LI
Aspects for Clouds
• SA3-LI should start looking at LI aspects of the already
deployed or soon-to-be deployed MNO cloud scenarios
• The specific MNO cloud work to be done in SA3-LI may
be part of the Rel 11 comprehensive LI WI, or part of Rel
12
• There are specific LI aspects for clouds to be studied,
due to:
– Cross-operational features of the clouds across multiple MNOs,
SPs, etc
– Cross-jurisdictional features of the clouds
• A set of relevant Cloud Use Cases for LI purposes
should be identified
• Relevant LI requirements to cover the identified cloud
use cases should be drawn

List of Potential Cloud Use Cases
relevant to LI Work
•
•
•
•
•

•
Use Case 1: File Sharing with single MNO
Use Case 2: MNO uses a Cloud server
Use Case 3: MNO uses a Cloud server that provides redirection
Use Case 4: The MNO hosts a cloud in its network
Use Case 5: SMB or Enterprise use multiple MNO networks
Use Case 6: Same as Use Case 4, but each MNO has a Cloud
Server that proxies (extension of Use Case 2)
Use Case 7: Same as use case 6, however MNO cloud server
provides redirection (extension of Use Case 2a) to the 3rd party
cloud App server
Use Case 8: SMB or Enterprise use multiple MNO with their own
Clouds (extension of Use Case 4)
Use Case 9: Enterprise extension to the cloud
Use Case 10; Local Break Out
Note: This is not an exhaustive list of use cases
