Business Continuity
This term takes into account all the technical concerns described in the previ-
ous scenarios, but also addresses a full range of non-technical practices and
processes, such as communications plans, regulatory notifications, natural
disaster safety practices, etc. Business continuity can be a huge undertaking,
and is typically a cross-departmental effort with many resources devoted to it.
It is usually not a project managed by a pure-play technology vendor.
BUaaS (Backup as a Service)
This is the term for an offering which provides backup services similar to what
is described above under Backup and Restore. In a typical scenario, BUaaS pro-
vides offsite (usually cloud-based) backup for on-premises or data cen-
ter-housed systems, protecting critical data against loss. There are vendors
who specifically provide this service, but complete solutions can also be archi-
tected using cloud-native services such as AWS Storage Gateway.
DRaaS (Disaster Recovery as a Service)
This is the term for an offering which follows most of the principles described
for general disaster recovery. However, similar to BUaaS, DRaaS is focused on
providing a cloud-based environment that becomes available after the failure
of an on-prem or data center-based application environment.
With DR it is critically
important to define your
business needs before
selecting a vendor and/or
designing a solution.
