Business continuity (or business reliance or business continuance) encompasses the activities that an enterprise performs to maintain consistency and recoverability of its data, operations, and services.
Solution Brief: HPE Shadowbase Business Continuity Solutions
Source: Spiceworks, “…while 95 percent of organizations have a disaster recovery plan in place, 23 percent never test their plan. The findings indicate a lack of testing and coverage gaps within disaster recovery plans may be leading to service outages in many organizations.” Disaster Recovery plans necessitate an IT infrastructure that is continuously available.
Figure 1 states the numerous costs per hour of downtime by industry: healthcare loses $636K, retail $1.1M, financial $1.5M, manufacturing $1.6M, and Communications/Media/Entertainment $2M, with the average at $1.4M.

The IDC defines four Availability Levels (ALs), AL1 – AL4, for classifying downtime. Each level corresponds to the number of 9s in the average availability after the decimal point. It also calculates the average cost of downtime for each level from the “Average Cost of Downtime per Hour” in Figure 1 (note: $1.4M USD per hour equals $388.88 USD per second, on average). Note that Shadowbase business continuity architecture satisfies the most demanding ALs (AL2 – AL4).
|Table 1 — IDC Availability Levels|
|Availability Level (AL)1||Shadowbase Architecture||User Notice Ability||Yearly Downtime2||Yearly Cost (USD)|
|AL1: 99.9%||N/A||All work stoppage, uncontrolled shutdown||08:45:56||$1,227,149.73 (USD)|
|AL2: 99.99%||User interruption, performance degradation, in-flight transaction interruptions||00:52:35||$122,714.97 (USD)|
|AL3: 99.999%||Performance degradation, automatic failover transfers||00:05:15||$12,271.50 (USD)|
|AL4: 99.9999%||None||00:00:31||$1,227.15 (USD)|

In Figure 2, AL and the amount of data loss is shown as improvement from the lower left to the upper right, while moving horizontally from an active/passive through sizzling-hot-takeover to an active/active architecture, and moving vertically from asynchronous to synchronous data replication technology.
RTOs of minutes to seconds is considered high availability, while RTOs of seconds to sub-seconds is considered continuous availability.
*Note: Shadowbase ZDL architectures are future synchronous technologies; specifications are subject to change without notice, and delivery dates are not guaranteed.
To gain the most potential from this data it must be current and available at any given time. The inability to access or update current data carries a significant business cost, possibly measured in many thousands of dollars per second.
HPE Shadowbase solutions offer a range of data replication capabilities to meet every application availability and data recoverability need. The overall return on investment in deploying a Shadowbase business continuity solution is positive, by preventing prolonged periods of downtime or data loss which can cost the business thousands or even millions of dollars. HPE Shadowbase data replication solutions support low-latency, uni-directional, and bi-directional data replication between homogeneous and heterogeneous systems and databases with scalability, selectivity, and sophisticated data transformation and mapping facilities. Shadowbase data replication software provides a business continuity solution to meet any business requirement.
