The decision about what kind of DR site an organization needs and its location requires careful planning and a balance of costs against any risks. Disaster recovery sites should be a part of a business continuity plan.
Internal DR sites are a good fit for companies with large information requirements and aggressive recovery time objectives. The additional data centers are used to maintain high availability of the data and resources. The internal site is typically a second data center and allows a company to recover and resume operations following a disaster at the primary center. Maintaining a second data center can be quite costly, but it might be worth it if the loss of service would result in massive financial loss.
Most internal DR sites are hot sites. They might also be used to load balance or provide better service to a geographic region during normal operation but are sized appropriately to handle the full load should one site become unavailable.
External DR sites are cheaper to operate but might take longer to respond to an outage. These can range in service from full management with DR as a service (DRaaS) to simple rentable empty data centers (cold sites).
A company can also use a cloud-based recovery site. Having DR sites in the cloud reduces the need for data center space, infrastructure and resources. Cloud DR sites can be cheaper and more viable for smaller companies, but security and bandwidth are concerns.
Other types of DR sites include mobile recovery services and colocation data centers. Mobile recovery services -- for companies that want to remain in the area of the disaster -- typically involve specially outfitted trailers that are positioned at pre-arranged locations. At colocation data centers, or carrier hotels, multiple customers install network, server and data storage devices, and connect to a variety of telecommunications and network service providers.
Many factors must be considered when considering where to locate a DR site. These factors can also be used to evaluate the suitability of external or could DR sites. These factors will often involve tradeoffs, so considering the recovery objectives and business continuity is essential.
Businesses often prepare for minor disruptions, but it's easy to overlook larger and more intricate disasters. Examine the top scenarios for IT disasters that disaster recovery teams should test vigorously.
DriverKit is the framework that allows developers to create device drivers that the user installs on their Mac. Drivers built with DriverKit run in user space, rather than as kernel extensions, for improved system security and stability. This makes for easier installation and increases the stability and security of macOS.
The DriverKit framework provides C++ classes for I/O services, device matching, memory descriptors, and dispatch queues. It also defines I/O-appropriate types for numbers, collections, strings, and other common types. The user uses these with family-specific driver frameworks like USBDriverKit and HIDDriverKit. Use the System Extensions framework to install and upgrade a driver.
