Answer» Following are the advantages of a cloud-based data warehouse: - Total cost of ownership is low: The low cost of cloud data warehouses is one of the reasons they are becoming more popular. On-premises data warehouses necessitate high-cost technology, lengthy UPGRADES, ongoing maintenance, and outage management.
- Increased performance and speed: To keep up with the expanding number of data sources, cloud data warehouses are crucial. Cloud data warehouses can easily and quickly integrate with additional data sources as NEEDED, and deploy the updated solution to production. Cloud data warehouses significantly improve speed and performance, allowing IT to focus on more innovative projects.
- Enhanced Security: Cloud security engineers can CREATE and iterate on precise data-protection measures. FURTHERMORE, cloud encryption technologies such as multi-factor authentication make data transfer between regions and resources extremely safe.
- Improved Disaster Recovery: Physical assets are not required to prepare cloud data warehouses for disasters. Instead, almost all cloud data warehouses offer asynchronous data duplication and execute automatic snapshots and backups. This data is kept across multiple nodes, allowing duplicate data to be accessed at any time without stopping present activity.
