Implementing fine-grained access control
The decentralized nature of microservices demands a nuanced approach to access control. This section aims to guide you through the advanced techniques and AWS services that can help you achieve a high level of access control.
IAM as the backbone
While the foundational role of IAM in AWS security was extensively covered in Chapter 3, its specialized application in a microservices framework deserves a deeper look. Given the distributed and often complex nature of microservices, IAM offers a set of tools that enable the creation of secure, scalable, and finely tuned access control architecture.
Role-based access
In a microservices setup, each service typically performs specialized tasks and requires access to specific AWS resources. By crafting IAM roles with permissions tailored to the unique needs of each microservice, you can adhere to the principle of least privilege. Importantly, long-term credentials such as IAM user access keys...
