Question
You have an upstream process that writes data to Cloud Storage. This data is then read by an Apache Spark job that runs on Dataproc. These jobs are run in the us-central1 region, but the data could be stored anywhere in the United States. You need to have a recovery process in place in case of a catastrophic single region failure. You need an approach with a maximum of 15 minutes of data loss (RPO=15 mins). You want to ensure that there is minimal latency when reading the data. What should you do?
Options
- A1. Create two regional Cloud Storage buckets, one in the us-central1 region and one in the us-south1 region.
- B1. Create a Cloud Storage bucket in the US multi-region.
- C1. Create a dual-region Cloud Storage bucket in the us-central1 and us-south1 regions.
