Before you optimize your storage, you must understand the performance profile of each service load and measure performance data such as Input/Output Operations Per Second (IOPS) and throughput.
Alibaba Cloud storage services provide various storage optimization solutions for different scenarios because no solution applies to all storage scenarios. Therefore, when you assess your storage requirements, select different storage solutions based on your service loads.
- Data volume
The total size of data can help you evaluate the storage capacity and costs.
- Requirements on data access frequency and response time
Alibaba Cloud provides various storage solutions that are different in prices based on the requirements on data access frequency and response time.
- Requirements on IOPS and throughput
Alibaba Cloud provides different storage classes based on the requirements on IOPS and throughput. You can select appropriate storage classes based on the requirements on IOPS and throughput to avoid unnecessary costs.
- Importance of data
Critical or regulated data must be stored securely for extended periods of time.
- Data sensitivity
Highly sensitive data must be protected not only from missing and damage but also from accidental or malicious modification. Data durability and security are equally important as storage costs.
