Yugabyte DB - The Distributed SQL Database for Kubernetes

Yugabyte DB - The Distributed SQL Database for Kubernetes

YugabyteDB, an open-source, distributed SQL database that is designed to support all PostgreSQL features with full wire-compatibility and address exactly these needs - massive scalability, high availability and geo-distribution of data. It’s unique sharding and replication architecture that makes it a perfect fit for Kubernetes-based orchestration.
In this session, we will take a look at the design goals and a hands-on demo of YugaByte DB on top of Kubernetes and how it can be deployed on multiple public clouds and across geographic regions. We will also discuss the best practices, you should employ when deploying distributed SQL databases like Yugabyte DB on Kubernetes. Topics will include best practices and strategies concerning deployment orchestration, persistent storage, scaling, and monitoring.

  4. Data on K8s Ecosystem is evolving rapidly

  5. Why Data services on K8s? Containerized data workloads running on

    Kubernetes offer several advantages over traditional VM / bare metal based data workloads including but not limited to: • Better cluster resource utilization • Portability between cloud and on-premises • Frictionless multi-tenancy with versioning • Simple and selective instant upgrades • Robust automation framework can be embedded inside CRDs (Custom Resource Definitions) or commonly referred as ‘K8S Operator’.

    BACKUP & RESTORE Backups and restores are a database level construct YugaByte DB can perform distributed snapshot and copy to a target for a backup Restore the backup into an existing cluster or a new cluster with a different number of tservers ROLLING UPGRADES Supports two upgradeStrategies: onDelete (default) and rollingUpgrade Pick rolling upgrade strategy for DBs that support zero downtime upgrades such as YugaByte DB New instance of the pod spawned with same network id and storage HANDLING FAILURES Pod failure handled by K8S automatically Node failure has to be handled manually by adding a new slave node to K8S cluster Local storage failure has to be handled manually by mounting new local volume to K8S
