The world is moving to distributed applications and architectures, and your database should too. Learn how you can deploy where you want, when you want, and how you want with a distributed SQL database. Migrate existing SQL applications to a distributed, multi-node architecture that can dynamically scale out and in. Our Transaction Engines (TEs) and Storage Managers (SMs) work together to ensure ACID compliance across multiple nodes. Deploy in a distributed architecture. When you deploy your database with multiple nodes, the loss of one or multiple nodes will not result in the loss of database access. Deploy TEs and SMs to meet your variable workload needs, or deploy in the different environments the teams in your organization uses: in private and public clouds, in hybrid environments, and across clouds.
