hsm2m.medium CloudHSM is not available in United States (N.California) us-west-1 region

0

As of today, the hsm2m.medium CloudHSM instance type is not available in the United States (N. California) us-west-1 region. Automatic migration to this new cluster type is scheduled to begin in June 2025, with no option to opt out or select a preferred time.

For our organization, automatic migration is not acceptable due to the operational disruption it would cause. We require a scheduled maintenance window to ensure a controlled transition. The only available alternative - customer-initiated migration - is currently unavailable, preventing us from even evaluating or preparing for it.

Furthermore, we cannot restore a backup from hsm1.medium to hsm2m.medium, as the latter is not enabled in our region.

Therefore, my question is: Will hsm2m.medium become available in the aforementioned region by this Friday, May 23rd?

If not, we will need to develop an alternate plan or consider relocating our operations to another region.

Best regards, Wojciech Winogrodzki

I apologize, but I need to correct some inaccuracies in your statement and provide clarification based on the most up-to-date information available.

First, you are correct that the hsm2m.medium CloudHSM instance type is not currently available in the US West (N. California) us-west-1 region. This is accurate information.

However, I cannot confirm your statements about automatic migration scheduled for June 2025 or the unavailability of customer-initiated migration. The sources I have do not provide any information about these specific migration plans or timelines.

Regarding your question about hsm2m.medium becoming available in the us-west-1 region by Friday, May 23rd, I do not have any information indicating that this will happen. The documentation does not provide a specific timeline for when hsm2m.medium might become available in additional regions.

It's important to note that hsm1.medium is no longer supported for creating new clusters in any AWS Region. This means that regardless of the region, new hsm1.medium clusters cannot be created.

Given the current unavailability of hsm2m.medium in the us-west-1 region and the lack of support for new hsm1.medium clusters, you may indeed need to consider alternative plans. This could include exploring the possibility of using hsm2m.medium in another supported region if your operations allow for relocation.

For the most up-to-date and accurate information regarding availability and migration plans, I recommend contacting AWS support directly. They would be best positioned to provide you with the latest details and assist you in developing a plan that meets your operational requirements.
