Question #: 29
Topic #: 8
[All Vault-Associate Questions]

You are performing a high number of authentications in a short amount of time. You're experiencing slow throughput for token generation. How would you solve this problem?

Show Suggested Answer Hide Answer
Suggested Answer: B

Batch tokens are a type of tokens that are not persisted in Vault's storage backend, but are encrypted blobs that carry enough information to perform Vault actions. Batch tokens are extremely lightweight and scalable, and can improve the throughput for token generation. Batch tokens are suitable for high-volume and ephemeral workloads, such as containers or serverless functions, that require short-lived and non-renewable tokens. Batch tokens can be created by using the -type=batch flag in the vault token create command, or by configuring the token_type parameter in the auth method's role or mount options. Batch tokens have some limitations compared to service tokens, such as the lack of renewal, revocation, listing, accessor, and cubbyhole features.Therefore, batch tokens should be used with caution and only when the trade-offs are acceptable.Reference: https://developer.hashicorp.com/vault/tutorials/tokens/batch-tokens1, https://developer.hashicorp.com/vault/docs/commands/token/create2, https://developer.hashicorp.com/vault/docs/concepts/tokens#token-types3

Haha, I can just imagine the poor server trying to keep up with all those authentication requests. Option C is the way to go, no doubt.

Option A? Nah, increasing token TTL won't solve the throughput issue. This is more of a capacity problem, not a token lifetime one.

D, for sure. Reducing the number of policies will lighten the load on the token generation process. Simple and effective!

I'm torn between B and C. Batch tokens could help, but a rate limit quota might be the more reliable solution. Hmm, decisions, decisions.

I think we should increase the time-to-live on service tokens.

Option C - Establish a rate limit quota. That seems like the most straightforward way to manage the high volume of authentications and improve throughput.
