Why does Cloud Migration matter?

Sooner or later, every organization needs to think about its cloud strategy. Large corporations face the issue of a constantly degrading IT landscape and need to reevaluate their applications regularly (e.g., every year). Under pressure from legacy technology, cloud-first strategies, and cost reduction, application owners must decide on a plan for their applications going forward.

Many companies have embarked on the journey and started large cloud transformation programs. From the business side, we observe that our customers are digitizing services and outputs to be faster and more responsive to what is happening in the market.

The starting point and goals can look very different for every organization. We see the following typical CIO drivers and goals for cloud migration as the broader category:

  • Move everything to the cloud as a strategic priority of the business and IT
  • Reduce costs
  • Become a digital product organization and drive the cloud to achieve a competitive advantage
  • Scale the business
  • Ensure business continuity by relying on cloud providers' excellent infrastructure
  • Increase the quality of service and performance of digital services
  • Have better access to innovation by leveraging cloud providers' AI/ML/security capabilities
  • Reduce FTEs needed (war for talent) for sourcing/managing IT resources



Gartner predicts, in 2027, the cloud will be considered a core aspect of ensuring business continuity and will be the pervasive style of computing. New workloads deployed outside of a cloud-native environment will be rare, and anything non-cloud will be considered legacy.

What does Cloud Migration mean?

A use case definition

Cloud Migration describes the effort of upgrading IT landscapes by moving applications to the cloud. The goal is to achieve a state-of-the-art application landscape that helps the organization scale its business and drive digitization and continuous transformation while having a reliable, secure, and cost-efficient IT infrastructure. Cloud Migration is the direction for organizations nowadays. It has become the leading paradigm of how companies source their IT infrastructure and provide digital services to their customers and employees.

The terminology used for the use case can vary; some talk about cloud migration or cloud transformation, and others apply the 6R assessment, a standard approach to cloud migration that we at LeanIX are also recommending to our customers. Your organization might also use other Cloud Migration Assessment approaches, which can be implemented in LeanIX.


What is the 6R of Cloud Migration?

The 6R strategy, LeanIX recommends leveraging, is an approach established by Amazon Web Services that has become a standard framework for cloud migration decisions.

6R: Six "r" stands for the six strategic decision possibilities for an application:

  • Rehost
  • Replatform
  • Repurchase
  • Rearchitect
  • Retain
  • Retire

LeanIX helps application and business owners address their CIOs' and CEOs' strategic objectives by providing the data needed for a comprehensive assessment and recommendation of a migration strategy that supports the business stakeholders to understand the reasons for each decision made in the process.

Benefit of the use case

Some facts and figures on how LeanIX customers achieved benefits by realizing Cloud Migration with LeanIX:

  • Saved 75% of the time manually collecting data from business stakeholders for migrating to cloud-native infrastructure by crowdsourcing data collection in LeanIX.
  • Accelerated decisions and migration project starts by 40% through insights into dependencies in the IT portfolio with LeanIX.
  • Completed 20% more cloud transformation projects on time by effectively planning architectural changes in LeanIX.

Which LeanIX Enterprise Architecture product do you need to solve the use case?
