State of Cloud Migration…What's Occurring Now, and What Will in 2015 and 2016

Cloud Application Migration


3

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 servicesRevise/Reuse

• Targeted changes to the application to address issues leverage the cloud

• Revise applications to leverage common servicesRefactor

• Move to more cloud‐aligned technology and platform services

• Integration with cloud operations and monitoringReplatform

• Lift and shift, minimizing changes, virtualization replatforming

• Physical to Virtual to Cloud (P2V2C), Virtual to Cloud (V2C)

Rehost

• Leave application as‐is; do not move to cloudRetain

• Application end of lifeRetire

• 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

Keys to Success: Application Migration at Scale

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


8

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.


9

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.


10

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.

– 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.

– 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.

– A larger number of business units leverage public cloud resources that are made up largely of AWS and a few other public cloud providers.

– 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.

– First cloud projects are a thing of the past, with most working on their second, third, or more major cloud deployments.

– Change management and cloud governance are becoming more commonplace and accepted by enterprises.
