AWS Key Management Service (KMS) has increased the request rate limit for a core set of KMS API operations, including Decrypt, Encrypt, GenerateDataKey, GenerateDataKeyWithoutPlaintext, GenerateRandom, and ReEncrypt. The request rate limits have been increased from 1,200 requests per second to 10,000 requests per second in US East (Northern Virginia), US West (Oregon), and EU (Ireland) regions. In all other regions where KMS is available, the limits are increased to 5,500 requests per second. These limit increases make it easier for you to scale your KMS operations.
