Overall Satisfaction with IBM Cloud Object Storage

We use COS as document storage for our document management system, and it serves its purpose: it stores documents that can be retrieved at a reasonable speed and at a reasonable price.

Some time ago, we submitted a suggestion for improvement regarding the backup functions of COS. Recently, a significant improvement called “backup policies” was announced. We are very much looking forward to implementing this, as it is one of the most important issues for an application that stores files with adequate backup in accordance with GDPR regulations.

Pros

  • Storing documents
  • Price
  • Backup policies
  • Redundancy mirroring
  • Reliability

Cons

  • GDPR back up policies per default
  • More polished UI (no that important tough)
  • Easier monitoring/notifcation when the bucket quota is reached
  • Storing files in a block storage would not be cost effective enough for us
  • Allowing to set quotas on bucket level, helps to control the cost
  • The fast deployment integrates well with our deployment process (application is ready in any minutes)
The reliability because that would be fatal for our use case, in three years we had one issue and that was a general problem of the IBM cloud, not the COS but there was no data loss. The cost effectiveness and the fast deployment which is crucial for a cloud business.
Starting our cloud business, which is in our case impossible without a powerful, fast and reliable object storage, so having that was one of the major key points to chose a hyperscaler.
Of course, the back up policies and the decoupling in this managed services, eased the operation of it too.
Mostly cost because most of them deliver a similar product and the decision for a hyperscaler (when you do not plan to use Multi Cloud) was not solely based on the object storage offering. Moreover, other components as K8s/postgres and the overall picture inclunding consulting during the ramp up phase, respectively the availability of data centers in certain regions. The latter was our main pain point regarding IBM in general.

Do you think IBM Cloud Object Storage delivers good value for the price?

Yes

Are you happy with IBM Cloud Object Storage's feature set?

Yes

Did IBM Cloud Object Storage live up to sales and marketing promises?

Yes

Did implementation of IBM Cloud Object Storage go as expected?

Yes

Would you buy IBM Cloud Object Storage again?

Yes

For the document storage scenario it works well, we cannot complain because of the cost or the speed. But we also tried it to store data for an Elastic, with the help of a plugin. In this scenario was neither fast enough nor cost effective. Therefore when you need faster storage, the COS is less appropriate.
