Analyst(s): Philip Dawson

Summary

Heavily customized applications can severely limit an organization's cloud migration options, restricting them largely to IaaS. I&O leaders should challenge their application delivery model and increasingly deploy commercial off-the-shelf applications to facilitate a modernization program.

Impacts and Recommendations

  • Standardized or lightly configured commercial off-the-shelf applications offer I&O leaders minimum control over app architecture, but maximum choice in terms of infrastructure and sourcing options
  • Moderately customized applications bifurcate I&O leaders' choices between modernization, rehosting and retirement, depending on budget priorities and agility demands
  • Heavily customized or in-house applications massively hinder I&O leaders' abilities to modernize infrastructure, restricting choices to IaaS, colocation, off-premises hosted, or internally hosted and fenced off for eventual retirement
    • On-Premises Apps Must Be Fenced Off and Prepared for Retirement
    • Bridging the Bimodal Differences
