Neil Millard 认为现代企业面临着遗留软件与新技术集成的挑战,这不仅涉及技术问题,还涉及组织问题,例如人员流动和商业风险。他指出,遗留系统通常被视为黑盒,没有人愿意触碰,直到出现问题。他建议,企业应该逐步替换遗留组件,而不是一次性重写整个系统。他还强调了安全风险,指出未更新的代码库是一个安全风险,因为新的漏洞不断被发现。 Darren Polk 认为企业经常将新功能添加到旧的遗留系统中,使其变得像弗兰肯斯坦的怪物一样。他指出,未更新的代码库是一个安全风险,因为新的漏洞不断被发现。他还指出,企业要求软件永远不会出现安全问题是不现实的。 Victor Farsen 认为企业总是有一些遗留系统,将新技术与旧技术结合可能会很困难。他指出,如果遗留系统无法满足需求、不安全,并且无法修复或重写,企业可能需要使其过时。他还指出,软件开发的特殊之处在于,即使是关键业务功能,也可能外包给承包商。他认为,企业应该增加全职员工比例,以提高软件开发的稳定性和长期规划。 长期以来,企业一直面临着如何处理遗留软件的问题。遗留软件通常是多年积累下来的,其技术架构陈旧,难以维护和升级。同时,企业又需要不断适应新的技术和业务需求,这使得遗留软件的现代化改造成为一个迫切的问题。 在技术层面,遗留软件与新技术的集成存在诸多挑战。首先,遗留软件的代码复杂,难以理解,这使得开发人员难以进行修改和升级。其次,遗留软件的接口不规范,与新技术的兼容性差。再次,遗留软件的安全漏洞较多,容易受到攻击。 在组织层面,遗留软件的现代化改造也面临着诸多挑战。首先,企业缺乏足够的资金和人力资源。其次,企业缺乏专业的技术人才。再次,企业缺乏有效的管理机制。 为了解决这些挑战,企业需要采取多种措施。首先,企业需要制定一个全面的遗留软件现代化改造计划。其次,企业需要投入足够的资金和人力资源。再次,企业需要加强与外部专家的合作。最后,企业需要建立有效的管理机制,确保遗留软件现代化改造工作的顺利进行。

Deep Dive

Chapters
This chapter explores the complexities of integrating legacy software with modern systems, highlighting challenges such as technical debt, security risks, and the difficulties of updating outdated libraries and dependencies. The discussion uses the analogy of an abandoned house to illustrate the situation.
  • Integrating legacy software with modern systems is challenging due to technical debt and security risks.
  • Outdated libraries and dependencies pose significant security vulnerabilities.
  • Updating old systems can be extremely costly and time-consuming.

Shownotes Transcript

#285: In the fast-paced world of technology, organizations often find themselves in a complex dance between embracing the latest advancements and grappling with decades-old infrastructure. This delicate balance is highlighted in today's enterprises as they attempt to integrate legacy systems with modern solutions like microservices. The challenges, both technical and organizational, raise critical questions about the future of software development and business strategy.

In this episode, we speak with Neil Millard, author of Confident Contractor, about how enterprises often cycle through waves of consultants every 18-24 months, disrupting continuity and expertise in managing these complex systems.
