Cloud… where is the money?

Example recent news:

Deutsche Bank signs 10 years multibillion-dollar IT deal with HP in Feb 2015

Solution: HP Helion OpenStack based Cloud Services

HP will provide computing capacity and data storage to host Deutsche's operations.

Deutsche will retain activities such as IT architecture and information security.

Cloud computing basics

NIST Definition:

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 is

composed of five essential characteristics, three service models, and four deployment

models.

Ref: NIST Cloud Computing Definition SP 800-145 http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf

5 Essential Characteristics

On-demand self-service

Resource pooling

Private vs. Public: Understanding the Trade-Offs

Enterprise 1 Enterprise 2

Private Cloud

Private Cloud

• Designated enterprise data center (or segment) managed centrally • Data center resources shared

by all divisions, protected by enterprise central controls • Divisions of enterprise act as

independent tenants • Some elasticity of resources;

good resource utilization; reduced cost of business

No Cloud

Enterprise IT

• Each enterprise division manages its own data center (or a subdivision)

• Exclusive local control of resources

• Internally borne costs and burdens of management • High-cost overcapacity, low

resource utilization

Virtual Private

Cloud

Virtual Private Cloud

• Third-party data center providers (public cloud characteristic) • Data center sharing is restricted

to only the divisions of this enterprise (private cloud characteristic)

• Divisions of enterprise act as independent tenants (private cloud characteristic) • Some elasticity; good resource

utilization; low cost of business

Community

Cloud

Community Cloud

• Consortium or a government scope data center (larger than private, but smaller than public) • Members of the consortium or

government agencies act as independent tenants

• Data center resources are shared by all members; consortium provides security, privacy and capacity

• Good elasticity of resources; high resource utilization; reduced cost of business

Public Cloud

• Third-party data center providers

• Computing resources shared by independent enterprises (tenants), protected by third parties in cloud

• Maximum elasticity; maximum resource utilization; low cost of business

DMTF Cloud Auditing Data Federation (CADF) Standard

Defines a full event model anyone can use to fill in the essential data needed to certify, self-manage

and self-audit application security in cloud environments. CADF is part of the DMTF’s

Cloud

Management Initiative.

Auditing using a standard such as CADF has many benefits:

Create and request customized views for Audit & Compliance data

Track regional, industry and corporate policy compliance using standardized APIs / Reports

Key event data is normalized and categorized to support auditing of hybrid Cloud applications

CADF assures consistent mappings across cloud components and cloud providers

Format is agnostic to the underlying provider infrastructure

Provides transparency for low-level operational processes

Source: http://dmtf.org/sites/default/files/standards/documents/DSP0262_1.0.0.pdf

Customer Benefits:

Ability to self manage auditing of their data

Similar reports from different Cloud service providers

Aggregate audit data from different Clouds / Partners

Source: http://dmtf.org/sites/default/files/standards/documents/DSP0262_1.0.0.pdf

Includes:

Resources by the role played in the event ex: Initiator, Target, Observer.

Actions used to classify the event by the activity that caused it to be generated.

Outcomes used to describe the outcome of the attempted action of the event.

CADF Event Model: Basic and conditional model components

Model Component

CADF Definition

OBSERVER

The RESOURCE that generates the CADF Event Record based on its

observation (directly or indirectly) of the Actual Event.

INITIATOR

The RESOURCE that initiated, originated, or instigated the event's ACTION,

according to the OBSERVER.

ACTION

The operation or activity the INITIATOR has performed, attempted to

perform or has pending against the event's TARGET, according to the

OBSERVER.

TARGET

The RESOURCE against which the ACTION of a CADF Event Record was

performed, was attempted, or is pending, according to the OBSERVER.

NOTE A TARGET (in the CADF Event Model) can represent a plurality of

target resources.

Name Description

storage Logical resources that represent storage containers.

compute Logical resources that are used to perform logical operations or calculations on data.

network Logical resources that interconnect computer systems, terminals, and other equipment allowing information to be exchanged.

data Logical named sets of information (objectified data) that are referenced and managed by services.

service Logical set of operations, packaged into a single entity, that provides access to and management of cloud resources (for a given domain).

system Logical resources that are a combination of several other [cloud] resources that operate as a functional whole, this combination being manageable (created, operated, audited, etc.) as a unit, i.e., offering some operations that could activate lower-level operations over each of the subresources.
