- Eliminates the need to embed long-term credentials with an application.
- Eliminates the need to provide access to buckets and objects without having to define static credentials.
- Temporary credentials have a limited lifetime, there is no need to rotate them or explicitly revoke them. Expired temporary credentials cannot be reused.

  // If no system-wide time zone database can be found a bundled version of the database is used instead.
  // If the time zone name becomes invalid during the lifetime of a CronJob or due to a change in host
  // configuration, the controller will stop creating new new Jobs and will create a system event with the
  // reason UnknownTimeZone.

* For HTTPS, **the server** needs to **have "certificates"** generated by a **third party**.
    * Those certificates are actually **acquired** from the third party, not "generated".
* Certificates have a **lifetime**.
    * They **expire**.
    * And then they need to be **renewed**, **acquired again** from the third party.
* The encryption of the connection happens at the **TCP level**.
    * That's one layer **below HTTP**.

computationally difficult to guess. They are globally unique identifiers which can be locally generated without contacting a global registration authority. UUIDs are intended as unique identifiers for both mass tagging objects with an extremely short lifetime and to reliably identifying very persistent objects across a network.

When you PUT an object in a versioning-enabled bucket, the noncurrent version is not overwritten. The following figure shows that when a new version of `spark.csv` is...
