While public cloud computing continues to mature as a technology, those in charge of public cloud solutions within enterprises adopt the technology at their own pace, and for their own reasons. Indeed, they are all on separate journeys, but with many of the same business objectives. In order to determine the progress of enterprises’ journey to the public cloud, Gigaom created a survey designed to understanding what is happening within enterprises that are adopting public cloud computing. Key items discovered in this survey include: 1. The use of public cloud computing is quickly expanding, and most organizations already exploit public cloud-based resources to run both critical and non-critical business systems. 2. Application development and testing are among the highest value uses of leveraging the public cloud, and most enterprises have moved from proof of concept to actual deployments in the last few years. 3. A larger number of business units leverage public cloud resources that are made up largely of AWS and a few other public cloud providers. 4. A surprising number of public cloud instances support the daily operations of many businesses, with a smaller percentage emerging as heavy users that leverage a massive amount of public cloud resources. 5. First cloud projects are a thing of the past, with most working on their second, third, or more major cloud deployments. 6. Change management and cloud governance are becoming more commonplace and accepted by enterprises. In this lunchtime keynote presentation, David Linthicum provides a look at what’s occurring right now as enterprises move to public clouds using real data from real adopters. What’s more, Linthicum will provide predictions around what is likely to occur in the world of cloud computing in 2015 and 2016, as well as recommendations around how you can exploit changes and growth of cloud-based platforms to your own best advantage.

Cloud Application Migration

Application Migration Common Methods and Approaches
• Replace application with SaaS service
• Build cloud native application with similar /
improved characteristics and features
Replace/Rebuild
• Develop and productize common business and
technical services
• Consolidate similar applications and services
Revise/Reuse
• Targeted changes to the application to address
issues leverage the cloud
• Revise applications to leverage common services
Refactor
• Move to more cloud‐aligned technology and
platform services
• Integration with cloud operations and monitoring
Replatform
• Lift and shift, minimizing changes, virtualization
replatforming
• Physical to Virtual to Cloud (P2V2C), Virtual to
Cloud (V2C)
Rehost
• Leave application Retain as‐is; do not move to cloud
Retire • Application end of life
• Determining the right migration
strategy for your app depends on
its level of cloud alignment, cloud
readiness, potential benefits
achieved from migrating, and risks
• Not everything will migrate
• Migration strategy selection also
depends on the target cloud
endpoint
• Public and other external cloud
endpoints may require 2x‐10x
effort
• Rehost and replatform strategies
minimize change for applications
that are either cloud ready, or
have higher risks or lower cloud
benefits
• Refactor and reuse strategies
accept the cost of change in return
for business benefits
• There are patterns, processes,
teams and tools to support each
strategy and each cloud endpoint

Rehost/Lift and Shift
• Pros
– Rapid migration
– Lower initial cost
– Current skillsets
– Lower functionality risk
• Cons
– Potential impacts from cloud
component failures
– Unpredictable performance and no
dynamic scaling
– Monitoring gaps
– Higher long term TCO
Refactor for the Cloud
• Pros
– Leverage cloud strengths: scalability,
automation
– Higher resiliency
– Greater transparency and metrics
– Lower TCO: resources on demand,
open source licenses
• Cons
– Slower migration
– Higher initial cost
– New tools and skillsets
– Extensive testing
Comparison of Application Migration Strategies
Migration strategies are a series of trade offs between time to market, risk, short term cost, long term cost
and ability to leverage cloud’s advantages.

• Successful migration to the cloud for large
application portfolios requires:
– Thinking and planning strategically
– Rapidly iterating through feedback loops
– Automating, measuring, continuously
improving
– Scaling at an accelerating pace
• Tools and platforms are still immature, so
approaches must align with the rapid pace
of innovation
• Strong governance, organizational impact
and skills retooling should not be
underestimated

Lack of Architecture, Leads to Poor Performing and Expensive Cloud Deployments

8. © 2013 Cloud Technology Partners, Inc. / www.cloudtp.com

To properly take advantage
of a cloud platform,
including IaaS and PaaS,
you have to design the
applications so that they're
decoupled from any
specific physical resource.

Of course, clouds can
provide an abstraction or
virtualization layer
between the application
and the underlying
physical (or virtual)
resources, whether they're
designed for cloud or not.

When this architecture is
considered in the design,
development, and
deployment of an
application, the utilization
of the underlying cloud
resources can be as much
as 70 percent more
efficient.
