B. Place a writable replica in the cloud-based data tier.
Detailed Explanation
Place a readable replica on-premises and place a writable replica in the cloud-based data tier is best suited for scenarios where employees are working on-premises and creating or updating product documents that will be available through a cloud-hosted website. By placing a readable replica of the database on-premises, employees can access the data quickly and efficiently without having to connect to the cloud-based data tier, which can improve performance and minimize latency. This is particularly important for situations where fast access to data is critical to the success of business operations.
At the same time, it is important to ensure that the data is stored securely and redundantly, which is why placing a writable replica of the database in the cloud-based data tier is recommended. This provides an added layer of security for the data, as well as redundancy in case the on-premises replica becomes unavailable for any reason. By placing a writable replica in the cloud-based data tier, automatic backups and disaster recovery can also be implemented, which can be critical in case of any issues with the on-premises database.
While placing read replicas in the cloud-based data tier may improve performance for remote users accessing the website, it does not provide a reliable source of data for employees working on-premises. Similarly, placing a writable replica on-premises would provide quick access to the data, but it would not offer the security and redundancy of having the data stored in the cloud.
Placing read replicas in the cloud-based data tier and placing a writable replica on-premises are not the ideal solutions for this scenario for several reasons.
Placing read replicas in the cloud-based data tier can improve the performance for remote users accessing the website, but it would not provide a reliable source of data for employees working on-premises. This is because remote users may have slower network connections and would benefit from accessing a closer data source, whereas on-premises employees can access the data quickly by using a local database. This approach may also introduce additional latency due to the need to synchronize data between the read replicas and the writable replica.
On the other hand, placing a writable replica on-premises would provide quick access to the data for on-premises employees, but it would not provide the security and redundancy of having the data stored in the cloud. This could be problematic in case of any issues with the on-premises database, such as hardware failure or natural disasters.
Therefore, the best approach for this scenario is to place a readable replica on-premises and a writable replica in the cloud-based data tier, which provides the best balance of performance, security, and reliability.
