1.1. What is Cloud Z DB?
- CloudZ DB is a Dedicated Managed DBaaS Platform that allows users to create and manage databases within minutes through a web console with just a few input details.
- It supports optimal HA (High Availability) models for different open-source databases.
- In the event of a service failure, Auto-Recovery ensures service continuity, and backup/recovery features allow for stable service restoration.
- With elastic capacity management, a small start is possible, and databases can be scaled up or scaled out as needed.
- A managed service for OS/DB Engine areas is provided, reducing database operation costs through automated operational features such as installation, monitoring, and backup.
1.2. User Roles
Users are granted Cluster and Namespace permissions, and the available functions are restricted based on the assigned permissions as shown below.
If higher permissions than currently assigned are required, please request a user with Cluster Admin privileges to change the permissions before use.

1.3. Terminology(Terms)
Namespace
A namespace is a logical unit used to partition and manage a cluster according to its purpose. Typically, namespaces are created for different project stages such as development, testing (staging), and production.
Service
A service refers to a DB instance, such as Redis or MariaDB, created in CloudZ DB.
Master-Slave
To ensure availability in case of failure, the database is configured in a master-slave structure, and data is replicated. The master is used exclusively for read/write operations, while the slave is designated for read-only operations.
Resource
The physical resources allocated for creating a DB instance, including CPU, memory, and disk.
Public network
A network that can be accessed from anywhere as long as there is an internet connection.
Private network
A network that is separated from the public network, inaccessible from external sources, and only accessible by systems within the same subnet.
Credential
A password used for user authentication when accessing the database or integrating a system with the database.
Connection String
A string that includes necessary information such as Host, Port, Username, and Password for database access and can be used to integrate a system with the database.
Command Line
A command that includes necessary information such as Host, Port, Username, and Password for database access and can be used to connect to the database.
Scale Up
The process of increasing database resources such as CPU, Memory, and Disk as needed.
Scale Out
The process of increasing the number of DB Nodes (typically Slaves) as needed.
Event
An event refers to an action triggered by performing functions such as DB creation and management.
