Release Notes

December 19, 2025​

New features​

  • Added a feature that allows selecting HTTP/2 as the target group protocol when connecting a target group to an HTTPS listener in an Application Load Balancer.

November 11, 2025​

Feature improvements​

  • Improved the load balancer creation and modification process to allow detailed listener configurations (e.g., connection idle timeout, packet settings, maximum connections).
  • Improved the target group creation and modification process to allow advanced configurations (e.g., health check port, traffic weight).

New features​

  • Added a feature that allows selecting HTTP as the health check protocol when the target group protocol is set to TCP.

July 24, 2025​

Added feature​

  • Monitoring metrics to check the status of instances within the target group have been added.

April 1, 2025​

Notice of kr-central-1 region termination​

  • Due to the termination of the kr-central-1 region, this service is no longer available in that region. Going forward, you can continue to use the service reliably in the kr-central-2 region.

May 13, 2024​

New features​

  • Added the source IP (Source IP Hash) routing algorithm for determining and routing targets within a target group. This algorithm ensures that clients using the same IP header are always directed to the same target.

March 6, 2024​

Improvements​

  • Enabled encryption when saving access logs to buckets by allowing the encryption option to be set to Enabled, ensuring high data security.
  • Expanded listener packet settings for ALB, allowing configuration of the X-Forwarded-For header with options to Attach, Preserve, or Remove.

December 14, 2023​

New features​

  • Introduced the Direct Server Return Network Load Balancer (DSRNLB) type. Operating at OSI layer 4, DSRNLB is suitable for scenarios requiring client IP preservation. For more details, refer to the DSRNLB documentation.

November 2, 2023​

New features​

October 23, 2023​

New features and bug fixes​

New features​
Bug fixes​
  • Resolved an issue where a load balancer in normal operation was occasionally displayed as offline.

June 23, 2023​

Improvements and changes​

  • Provided subnet-level health check IP visibility in target group details.
  • Modified target group creation to remove the Port field in step one.
  • Improved the load balancer creation interface to allow entry even when no VPCs are available.

May 31, 2023​

Improvements and changes​

  • Separated menus for load balancers and target groups, enabling resource-specific listings.
  • Classified load balancer types:
    • Application Load Balancer (ALB): Supports HTTP and HTTPS protocols with L7 rules for routing based on specific rules.
    • Network Load Balancer (NLB): Supports TCP and UDP protocols, routing traffic directly to the default target group.

November 30, 2022​

New features and improvements​

  • Added the ability to delete SSL certificates during listener creation or SSL configuration.
  • Introduced subnet-based instance registration during target group resource connection.
  • Enhanced status value display in the target group list.
  • Improved the interface for configuring traffic weights in target groups.

October 27, 2022​

New features and improvements​

  • Improved error messages for SSL certificate registration.
  • Enhanced the UI for displaying registered SSL certificate lists.
  • Added CIDR notation to the subnet selection list.
  • Adjusted Y-axis data values in monitoring for better accuracy.

September 15, 2022​

New features​

  • Added Proxy as a protocol option for target groups.
  • Enabled HTTP header policy settings when using HTTPS listeners.

August 29, 2022​

New features​

  • Introduced Application Load Balancer (ALB) with TLS encryption and decryption offloading via HTTPS listeners.

June 20, 2022​

Improvements​

  • Resolved an issue where monitoring charts did not display values when they were zero.
  • Enhanced sticky session settings in target groups with options like stickiness duration and sticky IP-netmask.

May 23, 2022​

Improvements​

  • Updated monitoring and detailed information features.

November 30, 2021​

New features​

  • Added the ability to associate public IPs with load balancers.

October 16, 2021​

Service launch​

  • Launched the Load Balancing service, which distributes traffic across multiple servers based on predefined configurations. It ensures efficient traffic management and uninterrupted service. For more details, refer to the official Load Balancing documentation.
