We are happy to announce the August update of Cisco Metacloud Private Cloud. This update addresses some key performance issues and provides a simple change that will help customers running multiple availability zones navigate between clouds.
Availability Zone Switching
Customers with multiple availability zones can now easily switch between their availability zones from the dashboard. After you login, you’ll see a simple dropdown menu in the topbar on the dashboard that shows each of your Availability Zones. Select the Availability Zone you want to go to and you will be redirected to the appropriate dashboard.
Improved Ceph Instance Snapshot Performance
Some customers reported that Instance Snapshots were slow when the image repository (“Glance”) was using Ceph as the storage backend. This was caused by a suboptimal workflow required to take a snapshot.
The old workflow required the entire image snapshot to be uploaded to Glance. This required copying from Ceph and putting it back into Ceph. The new workflow only requires the metadata of the Instance snapshot and not the entire local raw file be copied to Ceph. This change eliminates the majority of data from being copied, and therefore drastically improves performance - in most cases well over 200% faster.
Improved performance for API Endpoints with SSL
This update fixes the long standing performance issues we have had with the OpenStack APIs behind SSL. While we have had support for SSL based endpoints in the product for a long time the performance and the resource utilization on the underlying infrastructure were so poor that in most customer clouds we had administratively disabled it. With this update the default configuration of all API endpoints will be with SSL enabled. You can see the URLs for the API endpoints in the Project Access & Security Panel under the API Access tab.
Customers who are currently leveraging unencrypted API endpoints will have to update their CLI clients. To do this visit the Project Access & Security Panel and download the new RC file. Alternatively, you can set the OS_AUTH_URL environment variable to point to the new Identity URL found in the same panel.
