Mastering Active Directory - Second Edition

High availability

Based on the organization's requirements, we have to decide what the best solution to maintain high availability is. If it's a heavily used PKI, the availability of the CA role services is important. Service uptime can be guaranteed by running the service in a clustered environment or using advanced site recovery solutions such as Azure Site Recovery. Based on the maximum downtime an organization can afford, the investment in high availability products, the technologies used, and the general approach taken will also change.
