Streamlining Multi-Tenant Encryption with an Economical AWS KMS Key Strategy
In this article, we delve into a practical method for managing encryption keys within a multi-tenant SaaS environment by centralizing the approach. This strategy effectively addresses issues such as key proliferation, rising expenses, and the complexities of operations across various AWS accounts and services. We illustrate how adopting a centralized key management technique, utilizing a singular AWS KMS key for each tenant, can uphold security and compliance while also minimizing operational burdens as organizations expand.
