Tibero is an enterprise-grade relational database management system (RDBMS) designed to meet the evolving demands of modern IT infrastructures. As organizations worldwide accelerate their cloud-native transformations and seek cost-effective alternatives to Oracle, Tibero has emerged as a trusted, high-performance database solution. With advanced high availability (HA) architectures, Tibero ensures seamless database operations even in multi-node environments handling high-volume transactions.
TAC: The World’s Second Developed High-Availability Database Clustering Technology
Tibero Active Cluster (TAC) is one of Tibero’s core technologies and was the first of its kind developed in South Korea—and the second globally.
TAC enables seamless failover in the event of failures in the database engine, operating system, system hardware, or public network, ensuring zero downtime and rapid recovery.
For mission-critical workloads, TAC offers triple-node redundancy, exceeding traditional high availability (HA) setups, delivering exceptional performance when handling large-scale data processing.
With horizontally scalable active nodes, TAC provides elastic capacity expansion, while its Global Cache mechanism minimizes Disk I/O, significantly enhancing database performance.
Key Benefits of Tibero Active Cluster (TAC)
- Uninterrupted operation even in the event of failures in the DB engine, OS, system hardware, or public network
- Automated fail-over to a healthy node in case of a node failure
- Optimized performance with Global Cache, reducing Disk I/O bottlenecks
- Flexible horizontal scaling with seamless active node expansion
TAC in the Cloud: Overcoming Redundancy Challenges
Deploying active-active database clustering in the cloud is traditionally complex due to the lack of shared storage solutions (such as SAN storage and dedicated switches) and network limitations (e.g., absence of 10G private networks).
However, Tibero’s TAC overcomes these barriers, delivering on-premise-grade redundancy and performance in public cloud environments such as AWS and Azure. This allows enterprises to seamlessly transition to the cloud without compromising availability, stability, or performance.
Backed by its proven technology and reliability, TAC has been successfully deployed in high-performance, large-scale environments, including finance, public sector, and various enterprise systems. Today, over 1,500 organizations worldwide trust Tibero’s TAC to power their mission-critical applications.
