For senior developers who are ready to write code, integrating the appropriate AWS SDK library for your programming language and writing a few lines of code might seem straightforward, and may not take more than half a day. However, consider a large company with thousands of applications—like in my case—where this effort is multiplied a thousandfold. Moreover, these applications are developed in over 10 different languages, some of which may not even have an available AWS SDK. Therefore, using an agent that simplifies these operations into a single HTTP call to a sidecar service truly adds value.<p>Another consideration is operation; imagine that there are 10 different libraries maintained for this purpose, and if there is a new feature, say, you need all logs going to one place, making sure it is available in all languages would require a team with different programming skills to do so. Secrets agent, being language agnostic, you only need to change at one place, and someone else may have already done it for it or ready to do it, as it is open source project.<p>When it comes to cost saving, imagine scenarios where a junior developer improperly implements secret retrieval in a Lambda function, with retrieval occurring at every function invocation and each function handling 100 transactions per second. Such a single oversight can cost $1,000 a month, and if left unnoticed for a year—a common occurrence when the function appears to work—people often overlook further scrutiny as long as it functions.
