We are planning the first part of maintenance on our infrastructure to upgrade Enter Cloud Suite platform to Openstack Queens release.
This will involve the update of operating system for bug fixing and compatibility, the update of existing platform services to the latest stable Openstack release and the introduction of new services for our customers.
During operations, API components, Dashboards and Network resources of all regions will be affected. None of the currently other existing resources (Computing, Block Storage, Object Storage) will be affected, and they will stay active and running during the upgrade process.
In order to minimize API components and network disruption the update will be sequentially for all services. We expect a maximum downtime of 15 minutes for all API services and 30 seconds of network disruption during L3 and L2 services upgrade.
Below is the list of all services that will be affected during the updates and related impacts:
Authentication (Keystone) - Temporary inability of accessing on the platform.
Image Repository (Glance) - Temporary inability to create/retrieve images/snapshots and create instances.
Block Storage (Cinder) - Temporary inability to operate on existing and/or new volumes.
Automation (Heat) - Temporary inability of managing existing stacks and/or creating new ones.
Computing API (Nova) - Temporary inability to work on existing instances and/or create new ones.
Computing nodes (Nova) - Temporary inability to work on existing instances and/or create new ones.
Networking API (Neutron) - Temporary inability to work on existing networks, subnets, vpn connections and public ips and/or create new ones.
Networking nodes (Neutron) - 30 seconds of network disruption expected per virtual network port (virtual machines, virtual routers, dhcp servers, metadata server)
Detailed timeline of operations:
October 30th, 2018
10.00 - 18.00 CEST (UTC +2) -> Updating Computing services within Milan region.
We apologise for any inconvenience you may experience, and we confirm our full commitment in keeping our infrastructure as much updated and reliable as possible. Feel free to contact us for any possible question at email@example.com
