In part three of this series on cloud migration best practice, I will focus on migrating the application itself. If you haven’t had the opportunity to read our recommendations from part two, “Classifying Your Data,” check it out — those activities are crucial to the decisions addressed in this installment.While many organizations are aggressively moving applications to the cloud, they often set the criteria for a cloud service provider (CSP) without the necessary technical and operational due diligence. This widely observed error typically leads to migration delays, failures to attain expected business goals and general disillusionment with cloud computing. However, avoiding this disappointing experience is relatively easy. All it takes is executing an application portfolio screening process that takes a look at:The most appropriate CSP target deployment environment.Each application’s specific business benefits, key performance metrics and target return on investment.Each application’s readiness for cloud migration.Build a foundationThe first step in the screening process is determining the most appropriate cloud deployment environment. This practice establishes an operational foundation for subsequent service provider selections by using relevant stakeholder goals and organizational constraints to guide service model, deployment model and implementation option strategy decisions. Enterprises transforming their information technology should evaluate all available options by analyzing an app transition across three specific high-level domains and sub-domains, such as:IT implementation modelTraditionalManaged service providerCloud service providerTechnology service modelInfrastructure-as-a-ServicePlatform-as-a-ServiceSoftware-as-a-ServiceIT infrastructure deployment modelPrivateHybridCommunityPublicCloud computing domainsThese domains and sub-domains outline a structured decision process for placing the right application workload into the most appropriate IT environment. This is not a static decision: As business goals, technology options and economic models changes, the relative value of these combinations to your organization may change as well. Plus, single-point solutions are rarely sufficient to meet all enterprise needs. By the end of the cloud migration journey, an organization may require a mix of two,
