ABOUT GEO CLUSTERS
A geographically distributed data center is an IT infrastructure complex, united into a single whole by a common information field. Competently constructed complexes of this kind are capable, if necessary, of equalizing the load between the computational nodes, distributing it evenly, and in a situation of failure of one of them, other nodes take over the performance of its functions. The main goal of creating such complexes is to ensure fault tolerance without the targeted creation of a backup data center. In the event that one of the data processing centers fails, all of its functions are taken over by another data center.
ONE INFORMATION SPACE ON PHYSICALLY DISTRIBUTED RESOURCES
Centralized storage of information with geographically distributed replication allows each of the customer's distributed divisions to work with its own volume of data, which is synchronized and consolidated into a single database.
The creation of a high-performance geographically distributed data center is one of the most effective ways to meet the ever-increasing requirements for the performance and reliability of the computing infrastructure while increasing the amount of processed information, ensuring adaptability to changing needs for IT resources and reducing the cost of maintaining and developing IT infrastructure.
GEO CLUSTER KEY BENEFITS
The following basic requirements for the construction of territorially distributed data centers can be distinguished:
- data storage centralization
- centralized management of storage resources, backup and data recovery
- redundancy and the possibility of territorial distribution of system components
- system high availability
- high reliability and reliability of information infrastructure and system software
- system resource virtualization
- solution integration into existing information environments
- data security
