Which of the following is NOT a significant challenge faced by software engineers in a cloud-based company?

In a cloud-based company, the primary challenges software engineers encounter often revolve around technical aspects of development, deployment, and maintenance. Developing a budget plan, while undoubtedly important for the overall operation of the company, does not fall squarely within the core technical challenges that software engineers typically face in their daily work.

The significant challenges such as debugging at scale, managing out-of-control scaling, and the time-consuming nature of issue resolution are directly related to the complexities of cloud infrastructure and software architecture. Debugging at scale refers to the difficulties that come with identifying and resolving bugs in a distributed environment where multiple services interact. Out-of-control scaling implies challenges in managing resources effectively as applications grow, especially regarding performance and cost implications. Takes a long time to resolve issues points to the often intricate nature of troubleshooting in complex cloud architectures where dependencies and interactions between services complicate the resolution process.

In contrast, while developing a budget plan is a vital responsibility for managing a company's financial resources, it is more aligned with business strategy and financial management rather than technical execution, thus making it not a significant challenge specifically faced by software engineers in a cloud-based context.
