For mission-critical applications that have a low tolerance for downtime, Google
recommends that you use the 99.99% availability configuration. To be covered
under the production-level applications SLA
(99.99% monthly uptime percentage), you must build your network according to
this topology.
The 99.99% availability configuration requires four Cloud Interconnect
connections across two Google Cloud regions. The
most common production topologies use four Dedicated Interconnect
connections or four Partner Interconnect connections.
Another way to achieve the 99.99% availability configuration is to create two
Dedicated Interconnect connections in one region and two
Partner Interconnect connections in another region. For your
connection pairs, you must select different metropolitan areas and separate edge
availability domains.
You can achieve a 99.99% availability configuration with
Dedicated Interconnect or Partner Interconnect by
using the following documents:
To help you achieve a 99.99% availability configuration, we recommend that you
use interconnect connection groups. These groups provide you with information
about whether your configuration meets the requirements for your intended level
of availability. For more information about interconnect connection groups, see
Resiliency and SLA options.
