Cloud DB for MongoDB scenario

Available in VPC

NAVER Cloud Platform's Cloud DB for MongoDB easily and quickly builds MongoDB servers in cloud environments, and operates and manages them to enable stable cache service. The full sequence for utilizing NAVER Cloud Platform's Cloud DB for MongoDB is as follows.

The descriptions for each step are as follows.

1. Create application server
2. Set access environment
3. Test application server connection
4. Create MongoDB Server
5. Set ACG
6. Test MongoDB server connection

1. Create application server

First, create an application server (app server) that will communicate with the MongoDB server to be created from the Cloud DB for MongoDB of the NAVER Cloud Platform console. Currently, Cloud DB for MongoDB is only accessible within NAVER Cloud Platform. Thus, the application server must also reside in NAVER Cloud Platform. The application server (app server) can be created from the Services > Compute > Server menu of the NAVER Cloud Platform console.
You can refer to the following guides:

• Application server creation quick guide
• Application server creation guide

2. Set access environment

Once you've completed creating an application server, set up an access environment so that users can access the application server. You have two ways of setting the access environment, which are described as follows:

• Set up access to a private domain using the public IP of NAVER Cloud Platform
• Set up external access using the SSL VPN of NAVER Cloud Platform

For access settings using the public IP, you need to check the admin (root) password required for the server access, using the Get admin password feature. For access settings using the SSL VPN, you can access the MongoDB server by installing the SSL VPN client on your personal PC. It is advantageous for security to use the SSL VPN to use it for administrative purposes.
You can refer to the following guides:

• Public IP Guide
• SSL VPN Guide

3. Test application server connection

Once you complete setting up the access environment, use the terminal program to test if you can connect to the application server properly.
You can refer to the following guides:

• Connection test guide
• Download terminal program (PuTTY)

4. Create MongoDB server

After you complete testing the application server connection, create a MongoDB server that will communicate with the application server. The MongoDB server can be created from the Services > Database > Cloud DB for MongoDB menu of the NAVER Cloud Platform console without a separate service subscription request.
You can refer to the following guides:

• MongoDB server creation quick guide
• MongoDB server creation guide

Server redundancy configuration

To prevent data loss and minimize service impact if failures occur, you can set server redundancy. Cloud DB for MongoDB creates a primary DB server and a secondary DB server. It provides a feature that automatically fails over to the secondary when the primary fails. According to the internal algorithm of MongoDB, a new primary server is selected among secondary servers.

To configure server redundancy, select the cluster type as Single Replica Set or Sharding when creating the MongoDB server.

Manage monitoring and event

For MongoDB servers that have been created and are in operation, you can check monitoring for server performance and operating system status as well as events that occurred, and manage them for stable database service from the NAVER Cloud Platform console. You can also utilize the NAVER Cloud Platform's Cloud Insight for event and notification settings.

You can refer to the following guides:

• Monitoring guide
• Event confirmation guide
  • Event and notification settings guide

Manage management and administration permissions

You can create sub accounts in addition to the main user account, and set various management and administration permissions for Cloud DB for MongoDB. You can design permissions by utilizing the System Managed and User Created policies in the NAVER Cloud Platform's Sub Account.

You can refer to the following guides:

• Managing Cloud DB for MongoDB permissions
• Sub Account permission management guide

Store log and backup files

You can safely store the log files and backup files created from MongoDB servers using the NAVER Cloud Platform's Object Storage.

You can refer to the following guides:

• Log and backup file storage guide

5. Set ACG

Set the ACG (Access Control Group) for the MongoDB server to allow the access of the application server to the created MongoDB server.
You can refer to the following guides:

• ACG settings quick guide
• ACG settings guide

6. Test MongoDB server connection

Use the MongoDB Compass and test to see if you can properly connect to the created MongoDB server.
You can refer to the following guides:

• Connection test guide
