To expand the users outside the United States, the company needs to ensure high availability of the database and minimize the read latency for their users across the globe. The following two actions should be taken:
Create a multi-regional Cloud Spanner instance with "nam-asia-eur1" configuration or "nam3" configuration: Cloud Spanner is a globally distributed relational database service that provides strong consistency and high availability. To ensure 99.999% availability, it is recommended to create a multi-regional Cloud Spanner instance, which allows the database to be replicated across multiple regions. The "nam-asia-eur1" configuration or "nam3" configuration is recommended for a multi-region deployment, as they provide low latency and high availability across regions. By deploying a multi-regional Cloud Spanner instance, the company can ensure that their users can access the application with low latency and high availability, regardless of their location.
Create a minimum of two Cloud Spanner instances in separate regions with at least one node: To minimize the read latency for users across the globe, it is recommended to create at least two Cloud Spanner instances in separate regions, with at least one node each. This allows the application to read data from the nearest available instance, reducing the read latency for users. The two instances should be set up with replication, so that data is kept consistent across the instances. By deploying two Cloud Spanner instances in separate regions, the company can ensure that their users can access the application with low read latency, regardless of their location.
Therefore, the two recommended actions are: A. Create a multi-regional Cloud Spanner instance with "nam-asia-eur1" configuration. E. Create a minimum of two Cloud Spanner instances in separate regions with at least one node.
