What is YugabyteDb ?

YugabyteDB is an open-source, distributed, and highly resilient database designed for high-performance, globally distributed applications. It is built to provide features that combine the best aspects of traditional relational databases with the scalability and fault-tolerance required by modern, cloud-native applications

Features of YugabyteDb :

  1. YugabyteDB is designed with a distributed architecture, which means it can scale horizontally by adding more nodes to the cluster to handle increasing workloads.
  2. YugabyteDB is built to support global distribution of data, allowing you to deploy instances of the database across multiple geographical regions.
  3. YugabyteDB supports multiple APIs, including the Cassandra Query Language (CQL) for compatibility with Apache Cassandra and the YSQL API for PostgreSQL.
  4. YugabyteDB bridges the gap between NoSQL and SQL databases, offering the benefits of both worlds. It supports the flexible schema and horizontal scalability typical of NoSQL databases, while providing the familiar SQL querying capabilities.
  5. YugabyteDB is cloud-native and can be seamlessly deployed on popular cloud platforms like AWS, Azure, and Google Cloud.
