A Strategic Take on Cloud Storage Solutions — Part 3: Block Storage Optimization and Comparison

Optimizing Alibaba Cloud Block Storage

The first step to optimizing the Block Storage is to monitor and identify the cloud-based disk drives that are less used, overused, or not attached at all. The Alibaba Cloud Block Storage attaches and pre-configures specific storage for the system to use for read and write operations. The billing model only charges for what is utilized.

Deleting the Cloud Disks

The Cloud disks that are not attached or that are not being used for storage operations can lead to a great optimization scenario. It will reduce security threats and will account for a great cost-cutting scenario. In some cases, even after the ECS instance is terminated, the attached cloud disk might not automatically get detached and deleted. This scenario will keep incurring costs, so it is imperative that you keep a close check on such scenarios and manually delete the unused and unattached disks.

Deleting Old Snapshots

Snapshots are an important piece in the whole cloud storage scenario. Over time, a lot of snapshots can get accumulated, especially if you have configured a policy to take snapshots on a daily or weekly basis. It is advisable to delete the large number of snapshots that hold no value. Alternatively, you can set another policy to automatically delete the snapshots older than a certain date.

Adjust Capacity for Optimization

If you are using the enhanced SSDs (ESSDs), you can increase the performance level of the disk online to adjust the requirements. These requirements can be performance and capacity. For your overused cloud disk, you can scale up or down based on whether you wish to increase or decrease the capacity of the disk. This can lead to a perfectly optimized usage scenario and reduce the cost associated with Elastic Block Storage.


Let’s list out a few features for Apsara File Storage NAS, Object Storage Service, and the Elastic Block Storage from Alibaba Cloud. Below is a representation of the traditional application and internet application-based share scenario, where Elastic Block Storage, Apsara File Storage NAS, and Object Storage Service (OSS) are being used.

Wrapping Up

When it comes to extracting the most out of your storage service, optimizing is the way to go. Storage optimization is a practice where you continuously evaluate the changes in your storage requirements. These changes could be a result of an expansion or a strategical move from one business type to another. Therefore, it calls for strategic planning and selection of a storage solution.
