Redundancy of systems and data is an effective answer against many incidental hardware and software failures, cyber threats, and human errors. If any component of the data center fails, redundancy allows you to have another one ready to take its place. This reduces critical downtime situations, ensuring services remain operational without unexpected disruptions. When redundancy is accompanied by workload balancing and orchestration solutions across multiple networks and systems, not only is business continuity safeguarded, but data center performance is improved, both in terms of scalability and effective peak management of use. It also becomes easier to carry out maintenance activities because there is no risk of service interruptions and, in the same way, the effects of any human errors, which are not infrequent in the management of IT infrastructures, are mitigated.
The main technologies for data center redundancy
Among the fundamental technologies for the use of redundancy there is the use of virtualization which allows to set up virtual infrastructures capable of replacing the physical ones (but also other virtual ones) in case of need. Virtualization can affect all systems: servers, networks, and storage. It is supported by clustering, load balancing, workload orchestration, and data synchronization technologies. The entire data center can be duplicated in a geographically distant location to ensure continuity in the event of an incident with disaster recovery. Redundancy can be obtained both with a physical duplication of the data center systems and a virtual one, for example, by exploiting the resources obtainable as cloud services.
Consulting services to optimize systems
The use of cloud resources “on demand” is advantageous because it allows to contain the high costs associated with the redundancy of the physical systems and their maintenance. Under normal conditions, the cloud is used minimally to manage data synchronizations; the other resources come into play only in tests and emergencies. BinHexS offers business continuity consulting as well as data center modernization and cloud migration projects. Through the study of business needs, it can design and implement effective safeguarding and disaster recovery systems by exploiting the best technologies available, keeping implementation and management costs under control.
