Create Global Edge

Available in Classic and VPC

The following describes how to create a Global Edge on the NAVER Cloud Platform console.
To create a Global Edge, you need to first create a profile and then create an edge that belongs to it, and there are two ways to create an edge: Quick Start and Self Integration.

• Quick Start: create an edge with a simple setup.
• Self Integration: create a customized edge by configuring the details of the edge yourself.

Create profile

To create a profile, follow these steps:

1. Click the environment you are using in the Region menu and the Platform menu on the NAVER Cloud Platform console.
2. Click Services > Content Delivery > Global Edge menu, in order.
3. Click [Create profile] on the management page.
4. Enter the profile name on the Create profile page.
   • You can use letters, numbers, hyphens (-), and underscores (_) within a range of 3 to 35 characters
5. Click the [Complete] button.
   • This directs you to the management page with the created profile selected.

Creating an edge with Quick Start

To create an edge using Quick Start, follow these steps:

1. Click the environment you are using in the Region menu and the Platform menu on the NAVER Cloud Platform console.
2. Click Services > Content Delivery > Global Edge menu, in order.
3. Select the profile to create an edge for from the Profile drop-down list at the top of the page.
4. Click the [Create Edge] button.
5. Once the Edge settings page appears, select Quick Start, and then click the [Next] button.
6. Proceed with the following steps in order.
   • 1. Deployment configuration

1. Deployment configuration

Configure the default settings for the edge that you want to deploy.

• Edge name: enter the edge name
  • You can use letters, numbers, hyphens (-), and underscores (_) within a range of 3 to 35 characters
• Service Protocol HTTPS: select whether to use HTTPS as the protocol when making content calls. (Recommended) When using HTTPS, requested information is transmitted from the server to the browser in an encrypted state.
• Service domain: set the domain that the users will use to access the service by clicking on a link or entering the URL in their browser
  • Use NAVER Cloud Platform domain: use the automatically created domain in the type of "random number.edge.naverncp.com" in NAVER Cloud Platform
  • Use customer's domain: use domain other than the NAVER Cloud Platform domain. You need to enter the domain to use.
    • If you selected Service Protocol HTTPS, click the [Register certificate] button and register your SSL certificate.
• Service region: configure the edge server region to enable caching and delivery of content
  • If you select Korea or Japan, content caching and delivery can only be done through the edge servers located in the selected country
  • If you select Global (performance first), content caching and delivery can be done through edge servers located around the world over NAVER Cloud and partner networks
  • If you select Global (availability first), content caching and transfer can be done through edge servers located around the world over partner networks

2. Origin configuration

Specify the location where the content source is stored.

• Select NCP Object Storage Region: select the Region of Object Storage storing content
• Select NCP Object Storage bucket: select the bucket of Object Storage storing content

3. Caching

Configure how you want to control the cache.

• Default Caching (30 days): caches all objects, and sets the Time-to-Live (TTL) of the cache to 30 days

4. Creation completed

After reviewing the settings, click the [Complete edge creation] button at the top of the page.

• The created edge will be automatically added to the list and deployed.
• It may take several minutes to tens of minutes for an edge to be deployed.

Creating an edge with Self Integration

Deployment settings

Configure the default settings for the edge that you want to deploy.

Service settings

The service configuration items are as follows.

Global Edge Logging

Global Edge Logging allows you to log request information for each object and store it in Object Storage.
Detailed items are as follows:

Source settings

Configure the source of the content to be cached.

Source settings

The source configuration items are as follows:

Origin failover

Origin failover is a feature that forwards requests to a backup origin server according to the code when the origin server fails to respond.
Click the [Create] button to set up forwarding rules. Detailed items are as follows:

Cache settings

Configure how you want to control the cache.

Default Caching

The default cache settings for all objects are as follows:

Negative TTL(s)

Using Negative TTL(s) caches error responses from the origin server, reducing the load on the origin server.
When you click the toggle button to turn on the feature, it is applied by default for 10 seconds to 4xx and 5xx HTTP code responses.

Bypass Query String

By using bypass query string, requested URLs that contain specific strings are not cached and are bypassed to the origin server. To configure settings, follow these steps:

1. Click the Bypass Query String toggle button to turn on the feature.
2. Enter the string that will be used as the bypass criterion in the query string input field and click the empty space around the input field to recognize the string.
   • Repeat this process to enter multiple strings.
3. Click the [Save] button after entering all the desired strings.
   • After saving, you can click the [Edit] button to edit the strings if necessary.

Cache Key Hostname

When configuring cache keys, you can select the hostname to use. Detailed items are as follows:

Cache key Ignore Query String

By default, query strings are not used in the cache key, but you can control object differentiation by changing whether or not they are included or by allowing only specific strings to be used. Detailed items are as follows:

Ignore case sensitivity in cache keys

Generally, origins are considered to be case-sensitive with respect to the URL's path and file name.
When caching requests, the edge server determines how to handle the case sensitivity of URLs.
Some origin servers, like those using Microsoft IIS, do not differentiate between uppercase and lowercase. If the origin does not distinguish between uppercase and lowercase, activate this feature.

Remove Vary Header

If the response from the origin server contains a Vary header instead of Accept-Encoding, the edge server will not cache the response.
If you turn on the feature by clicking the toggle button, the origin server will respond with a Vary header, but the Vary header will be removed to allow the object to be cached when the actual content is the same.

Edge Auth

To prevent unauthorized sharing of content, you can generate a one-time token and configure it to respond to authenticated requests only. To configure settings, follow these steps:

1. Click the Edge Auth toggle button to enable the feature.
2. Select your preferred authentication method between Signed URL and JWT.
   • Signed URL: embed authentication credentials in the URL, allowing all clients to access it
   • JWT: generate a JSON token with authentication information and place it in the HTTP header to identify the client
   • Media Vault: embed authentication credentials in the URL, allowing all clients to access it (service region: available only in Global (performance first), Global (availability first))
3. Enter the desired name in the Token name input field and click the [Create] button in the token key field.
   • The token will be generated and displayed.
   • Every time you click the [Create] button, the key value of the token changes.

Rule builder

Configure how to create detailed cache rules and control content.

Detailed cache rules

You can set rules for caching objects on the edge server.
You can click the [Add cache rules] button to add up to 10 rules. Detailed items are as follows:

You can also click the [Advanced settings] button to set more detailed rules.

When you save the cache rule, a list of rules is generated.

• You can easily view the saved contents in the list.
• The priority is automatically applied in the order in which they are saved. To change the priority, click , or drag .
• To edit the saved rule, click to edit and click the [Save] button.
• To delete the saved rule, click .

Managed rules

When using CDN services, you can configure frequently used features. Detailed items are as follows:

HTTP Header Modification

You can set it to override HTTP headers that are sent when making a request to the origin server or when responding to a client. To configure settings, follow these steps:

1. Click the [Modify HTTP Header] button.
2. Select the type of header to override.
   • Modify Origin Request Header: redefine the HTTP header transmitted when forwarding requests to the origin server
   • Modify Client Response Header: redefine the HTTP header sent when responding from the server to the client
3. Enter the rule.
   • Rule Name: enter the Rule name
   • Rule Configuration: rules detailed settings
     • Action: select the action to perform from add, edit, and delete
     • Header Name: enter the HTTP header to be targeted by the action
     • Value: if you selected add or edit, enter the header value to apply
4. Click the [Save] button.
   • The rules are saved and a list is created.
   • To edit the saved rule, click to edit and click the [Save] button.
   • To delete the saved rule, click .

Optimization

Configure ways to improve performance when delivering content to users.

Compressed transmission

Using compressed transmission enables content to be delivered faster by applying compression when delivering content to client browsers or devices that support GZIP or BROTLI compression.
By clicking on the Toggle button to turn on the feature, you can specify the GZIP or BROTLI header in the Accept-Encoding to compress the content.

• Compression transmission support extension: css, js, json, xml, html, ttf, otf, woff, woff2, eot

Large file transfer

Using large file transfer allows content to be sent in pieces instead of a single file when requesting content from the origin server, improving origin offloading.
When you turn on the feature by clicking on the Toggle button, optimization for large file transfers will be applied.

Access control

Adjust the range of access to the edge.
You can create a whitelist or blacklist and add three types of access control conditions.

• Whitelist: allow access for requests that match the conditions
• Blacklist: reject access for requests that match the conditions
