This topic describes the concepts related to OceanBase Admin Toolkit (OAT).
OAT: a platform for installing and managing products and components in the OceanBase ecosystem.
OceanBase Database: a distributed relational database that supports the MySQL and Oracle modes.
Ecosystem products: OceanBase ecosystem products, including OceanBase Cloud Platform (OCP), OceanBase Developer Center (ODC), OBSharding, and OceanBase Migration Service (OMS).
- OCP: a platform for managing OceanBase clusters.
- ODC: a platform for database development.
- OMS: a service for data exchange between homogeneous or heterogeneous data sources and OceanBase Database.
- OBSharding: a dedicated proxy service of OceanBase Database, which receives SQL requests from users, forwards them to the optimal target server, and finally returns the execution results to users.
Components: OceanBase components, including MetaDB, OBDNS, and InfluxDB.
- MetaDB: a container-based OceanBase Database service with a built-in OceanBase Database Proxy (ODP) for external access. It stores the metadata of OCP, ODC, and OMS.
- OBDNS: a DNS and Tengine-based load balancing service that is deployed by using a container. In the absence of external load balancing devices such as F5, you can use OBDNS as a software load balancer. However, you must set the DNS server to the server where OBDNS resides on your client. It provides load balancing and high availability capabilities for OceanBase ecosystem products such as OCP.
- InfluxDB: a container-based time-series database service that stores monitoring data for data transmission in OMS.
- NLB: an OpenResty-based load balancer that features high availability, simple deployment, and low resource consumption. It provides load balancing services for OceanBase ecosystem products such as OCP, ODC, and OMS.
Tools: optional O&M tools available upon delivery. Currently, only OBLB is available.
- OBLB: an iptables-based load balancing service. In the absence of external load balancing devices such as F5, you can use OBLB as the software load balancer for OceanBase clusters.
