The Big Switch

Virtualized Data Center and Cloud Introduction 2

“We will probably see the spread of ‘computer utilities’ which like present electric and telephone utilities, will service individual homes and offices across the country”

Kleinrock, 1969

“Goodbye ‘World Wide Web.’ Hello ‘World Wide Computer’ ”

Carr, 2008

Next…Cloud Computing


Business Drivers and IT Challenges


• “70% of the budget to keep IT running, 30% available to create new value”

“…that needs to be inverted”

• Weeks of planning, justification, and deployment and then we’re stuck with it for 5 years – even if our needs change in a month…”

“…or we could just buy it as a service – right now”

• “Most of our legacy applications are stable and predictable”

“…we need to incrementally improve efficiency without disruption”

• “but, new, more dynamic and fluid approaches to IT must also be leveraged for new applications and changing legacy applications”

“…new, revolutionary IT models are essential as well”

Data is Growing Exponentially

• Shift towards user created, unstructured data changes storage needs Secondary storage is the new

primary storage• File-based storage raises major

management issue Online ingest of and access to large

volumes of content

:Virtualized Data Center and Cloud Introduction


Top Threats in the Cloud

• Abuse and nefarious use of Cloud computing• Insecure interface and APIs• Malicious insiders• Share technology issues• Data loss or leakage• Account or service hijacking• Unknown risk profile

• Loss of governance• Lock-in• Isolation failure• Compliance risks• Data protection• Insecure or incomplete data

deletion• Malicious insider

Governance, Risk and Compliance 6


Why GRC & Security is Important


• Breach• Regulation• Other?

Consequences• Risk of fines for failed audits

TJX – total cost > $1b for breach

Heartland – estimated at more than $140m

• Compliance concerns stall virtualization and Cloud

• Audits time consuming and costly

• Concerns of identifying risk and proper valuation


Virtual Data Center Business Drivers & Benefits• Application level business continuity

Simplify and improve disaster recovery process Ensure important applications receive resources required to meet business needs

• Improved productivity, operational flexibility, and increased availability Optimize resources - consolidate of servers, storage, and fabrics Reduce hardware, power, cooling and space requirements Reallocate resources with no downtime Quickly and easily provision new servers

• Secure desktops Centralized management Patch gold copies once, with automated roll-out

Benefits of Cloud• IT provisioning in minutes instead of weeks• Application development, testing, and QA are flexible and self-

service enabled• Relocation from test and development to production is

predictable and seamless• Resources scale fluidly to meet growing or reduced need• Service level easily adjusted after the fact• Resources granularly metered to optimize utilization and cost


IT has more time to focus on the strategic; the LOB has more time to focus on the business

Cloud Tenets

http://csrc.nist.gov/publications/drafts/800-145/Draft-SP-800-145_Cloud-definition.pdf


Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in.

NIST

Rapid Elasticity

• Capacity can be scaled up, down, in, or out dynamically• Scaling is immediate• Licensing is also built to scale• Underlying hardware can be anywhere geographically


Definition


Cloud systems automatically control and optimize resource use by leveraging a metering capability 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.

NIST

Measured Service

• Infrastructure operational costs incurred on a pay-per-use basis• Contractual obligations tied

to price tiering No obligation has the

highest price

14

Definition



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).

NIST

Broad Network Access

• Network is essential to consume the service• Endpoints can be of any type:

Smartphone, tablet, notebook, laptop, desktop, server, other applications

Definition


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.

NIST

Resource Pooling

Shared Resources• Infrastructure and services run on shared

physical devices (e.g., multi-tenant)


Definition


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.

NIST

On-Demand Self-Service

• On-Demand Customers incur no infrastructure

capital costs and are charged an Operational Expense (OPEX)

Workload forecasting unnecessary

Demand trends are predicted managed by the provider

The underlying hardware may be anywhere geographically

• Self-service Resources directly/indirectly

reserved by the customer via a web based portal and appropriate APIs


Definition

Service Model Description Examples

SaaSConsumer can use the provider’s applications running on a Cloud infrastructure. The consumer does not manage or control the underlying Cloud infrastructure.

Mozy, Zimbra, Salesforce.com, Intuit, Microsoft, Google Apps, Concur, Zoho, Cisco Webex

PaaS

Consumer deploys on the Cloud infrastructure applications that they have created or purchased applications using programming languages and tools supported by the provider.

SpringSource, Google App Engine, Force.com, Windows Azure, Appistry, Engine Yard, Flexiscale, Bungee Connect, Longjump

IaaS

Consumer provisions 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.

A Before View: Traditional Development Environment

• Developer Writes code on workstation in an individual development environment (IDE , ex .NET, Java, or Python) Pushes code to Development Server Code runs through a successful build EXE is sent to QA/Test When passes QA/Test, application is moved to production environment

• Customer uses production image• All infrastructure is “silo’d”

Infrastructure belongs to the department Even engineering is silo’d

Windows or Linux

CustomerDev Server QA/Test Production

Copyright © 2011 EMC Corporation. All Rights Reserved. Cloud Services 34

Transformation to IaaS to PaaS to SaaS

• Developer WS runs IDE IDE is linked live to PaaS environment Engineer can self-serve VM’s for test and QA or other IDEs

• VM policy pushes code to top tier infrastructure It is scale tested then turned over to production

• Linkages via SOAP/REST are built into the apps Apps can bind on the fly Apps cross private & public Cloud boundaries
