Gartner Insights Abstract

采取持续现代化方法优化遗留应用

Published: 10 July 2024

Summary

遗留应用往往会阻碍业务价值的持续交付,但全面淘汰和替换这些应用不仅成本高昂,而且风险大、耗时长。应用和软件工程领导者应采取持续现代化方法,最大限度降低遗留应用优化的成本、风险和影响。

Included in Full Research

概述

主要发现
  • 基于淘汰和替换方法的应用现代化,就成本、风险、时间和影响而言,可能会对企业机构造成巨大颠覆,其负面影响往往超过了所能带来的收益。

  • 遗留应用并非为支持持续交付而设计,其中的部分组件会形成阻碍(或摩擦点),对业务运营产生负面影响。

  • 现代化团队与产品团队缺乏协调(且业务领导者缺少参与),不利于持续现代化工作的推进。

建议

为有效优化企业机构的遗留应用,应用和软件工程领导者应:

  • 以持续现代化方法取代原有的淘汰和替换项目,聚焦遗留应用对业务造成的具体阻碍,而不是将遗留应用视为一个需要消除的问题。

  • 实施持续现代化,识别、优先考虑并消除最严重的摩擦点,即应用支持不佳的业务功能。

  • 构建持续现代化文化,与产品和平台团队合作创建任务清单并确立一致的进度和节奏,及时以迭代的方式消除遗留应用形成的摩擦点。
