Q. What is NAVER Cloud Platform’s WebtoB?

Korea's representative next-generation web server, WebtoB, is provided as a server installation type.
It can reliably handle large amounts of client requests while consuming less server resources.
It provides load balancing and failover through clustering and provides differentiated functions. (WEB API, JEUS optimal linkage, output compression, etc.)

Q. What are the features of WebtoB?

Online Transaction Processing (Online Transaction Processing, OLTP): WebtoB is designed to be suitable for processing large-scale transactions on the web, effectively solving problems on web systems such as delays in processing speed and server down.
WebtoB architecture: WebtoB is largely composed of system processes, web containers, server processes, and administrator tools. The administrator tool, WSM (WebtoB System Manager), is responsible for operating all processes in WebtoB and supports the entire system to operate efficiently.

Q. How do I create a a WebtoB server?

You can create it by selecting the WebtoB server image from the console's Compute > Server menu.
Create a server with the specifications you want and add storage as needed.
You will be charged monthly or hourly. You can use this service after you create a server and configure the environment.
To use the WebtoB web service, you need to apply for a public IP address and add the Server Port port in the ACG settings (the port is changeable).
After connecting to the console, you can easily create a server using the following steps.

Q. Can't access the Node.js Web service.

To use WebtoB web service, you need to apply for a public IP address and assign it to the server, and add the Web Server Port port to ACG.
If you still cannot access it after checking the public IP address and ACG settings, your web server process might be stopped; execute the restart command on the terminal to restart the process.

Create WebtoB server

To create and access the WebtoB server, follow the steps below in order.

① You must select an ACG. Select one of the existing ACGs including the default ‘ncloud-default-acg’.

You can select up to 5 ACGs of your own.
You must select an ACG to activate [Next] button so that you can proceed with the setting.

② If you want to create and configure a new ACG besides your existing one, select Create a New ACG.

③ Click [Next].

Create a new ACG

The following process shows how to set a firewall by creating a new ACG.

① In Create a New ACG, click [Create ACG].

② Enter an ACG name.

③ In ACG setting, enter a protocol, an access source, and an allowed port to create.

Protocol : Select between TCP, UDP, and ICMP.
Access source : Enter an IP address or ACG name.
Allowed port : Specify a single port or range.
For a terminal connection, the rule for SSH 'TCP/22' must be set in ACG of a server to be connected. To add rules, specify a protocol, an access source, and an allowed port, and click [Add].

④ If the service ports are all added, click [Create].

Step 6. Confirm

Confirm the settings.

① Make sure that the server image, server, login key, and ACG are set properly.

② After the final confirmation, click [Create server].

This may take several minutes or longer to be completed.

Check server list

Check if the created server is in the list.

① The server you have created will appear in the list.

② Wait until the server is created, the WebtoB package is installed, and the server status becomes Running.
