Presentation that discusses how to prepare the enterprise to move to the cloud through consolidation, optimization, automation, and orchestration (Jim Lepianka).
4. Going to the Cloud
Keys to achieving 'the Cloud'.
From Virtualization to Orchestration.
Getting to the cloud is as much a mystery as what
to do once there. We will discuss the types of
clouds, the 4 steps to get there and what we can
do now to prepare your enterprise for the leap.

6. Cloud Definition
Definition
• Cloud computing is a pay-per-use model for enabling available, convenient, on-demand network
access to a shared pool of configurable computing resources (e.g., networks, servers, storage,
applications, services) that can be rapidly provisioned and released with minimal management
effort or service provider interaction. This cloud model promotes availability and is comprised of five
key characteristics, three delivery models, and four deployment models.
Key Characteristics
• On-demand self-service
- SaaS
- Public
• Ubiquitous network access
- PaaS
- Community
• Resource pooling
- IaaS
- Private
• Location independence
- Hybrid
• Homogeneity
• Rapid elasticity
• Measured service

7. XaaS, the concepts included in the
Cloud
• EaaS, Everything as a Service, the transformation of IT
from a physical, well established environment into a
capability that is available at people’s fingertips without
knowledge of where the assets are.
• SaaS, Software as a Service, an environment where
users can run predefined applications directly from their
web browser.
• PaaS, Platform as a Service, an environment in which
the user is provided with a rich environment in which he
can run his applications as long as they are
programmed in one of the languages supported by the
platform (Java, Python or .Net)
• IaaS, Infrastructure as a Service, an environment that
provides the user with processing power, networking,
storage and the other necessary resources allowing him
to run his software and applications

8. 4 Cloud Deployment Models
Private Cloud
• Enterprise owned or leased
Community Cloud
• shared infrastructure for specific community
Public Cloud
• Sold to the public, mega-scale infrastructure
Hybrid Cloud
• composition of two or more clouds

14. 4 Key Steps
Consolidate
• Consolidate Applications and Services through Virtualization
• Leverage Composite Services instead of individual services
Optimize
• Pair Virtualization with management
• Integrate Lifecycle Management disciplines
• Integrate Management across domains and spaces
Automate
• Provisioning of services through Templates
• Reservations are created on demand
• Automation always scales; people do not
Orchestrate
• Dynamically instantiate and decommission VMs based on user load
• Monitoring captures and fires alerts; Monitor the entire system not just parts
• Capacity for configuring, managing and reporting
Virtualization + Automation + Service Management = Cloud

Lessons Learned
• Monitor the entire system; not just parts
• Only use standards; stay away from Proprietary systems
• Reengineer the architecture around Virtualization instead
of dropping it in and then expecting 100% of the benefits
• Lower costs by removing hardware and the related support
costs
− Multitenency is the best way to drive down cost and attain ROI

Lessons Learned
• Make your services consumable :
− Prioritize based on business requirements
− Consumerize by providing you catalog; must cover all businesses
not just your cloud services
• Maintain Security – Define your requirements before
looking for vendors
− data at rest/encryption
• − Country where data will reside, local laws
− Monitoring/ 3rd Party Auditing and certifications
• Cloud is as much about process and policy as it is about
technology

Lessons Learned
• Organizations struggle to maintain low to no value
applications; perform Application Rationalization and
define your Service Catalog
• You cannot control things you do not know about; Catalog
your offerings
• Ensure you can point to every server in the Datacenter and
you know:
• − What is running on it
− Who is responsible
− What happens when it fails

Lessons Learned
• There is no big bang approach to get to the cloud; start
small and grow
• Metrics will need to be tested, refined, implemented,
refined further and re-implemented long after the
implementation phase closes
• A knowledgeable partner can reduce time loss due to
forgotten steps (like implementing technology only to be
• forbidden by policy)
