Saber Ahmadzai I can read this question in so many different contexts. What specific scenario are you referring to?
Costs for maintaining a system could apply to any number of contexts:
- Deploy and never touch the code
- Deploy and continue developing
- Expanding infrastructure to support increased usage.
- Addressing technical debt due to tight deadlines.
- Challenges related to impact of changing code in a much larger and more complex code bases.
- Poor design leading to brittle code that requires more effort to develop in.
- Preserving backwards compatibility can take more effort to avoid breaking changes.
- Support staff needed to assist with technical problems.
- Hosting costs accrued over time.
- Upgrading dependencies can be very involved.
- Training people to use the system.
- Training people to support the system.
These are just a few that come to mind from my own experiences.
