I have my own business and I want to update the software in it. We need to add modern software product technologies. On which platform is it best to write business software today? Where can I read more information?

It depends on what kind of software you are writing. An application or program for Windows, or for a website something. Of course, it is necessary to further check how the program works and how much memory the computer takes. Special programs will help you to optimize this program. And to write the code, if you are a programmer then Notepad or some code editor will be enough for you. Or you can go to the professionals as you've been told. Who knows what factors in this area you still do not know.

While DevOps can be beneficial for many businesses, there are some cases where other approaches may be more appropriate. For example, if a business is focused on building and maintaining a single, stable product, traditional software development methodologies such as the Waterfall model may be more suitable.
