What solution should an architect consider for a simple data update within Salesforce?

Flow Builder is considered the best solution for simple data updates within Salesforce due to its user-friendly, visual interface that allows users to create complex logic with ease. It provides a robust set of elements and features that facilitate various data manipulations, including creating, updating, and deleting records.

With Flow Builder, users can easily set up record-triggered flows that execute automatically when a record is created or updated, making it particularly efficient for handling data updates without the need for writing code. It also supports more advanced functionalities, such as loops and decision points, which can be utilized even for relatively straightforward updates.

In contrast, while Process Builder is also a viable option for data updates, it has limitations compared to Flow Builder, particularly in terms of handling larger data sets or more complex business processes. Custom Apex would be more suited for scenarios requiring complex calculations or integrations that Flow Builder cannot handle, making it an over-engineered approach for simple updates. Outgoing webhooks are primarily used for sending data to external systems rather than directly updating Salesforce records, making them unsuitable for this specific requirement.
