Changes#

  • The new Direct Connect service provides L3 connectivity between the corporate network and K2 Cloud. It ensures a direct link with low latency and guaranteed bandwidth (1, 10 and 25 Gbps). If multiple links are connected to different devices on the cloud side, the service ensures high availability via the BGP protocol.

    Links connected to the same device can be grouped. Each connection or group of connections can have multiple virtual interfaces (VLANs) and its own BGP peering. You can delete virtual interfaces and create new ones with different settings.

  • The new Application Load Balancers (ALB) service distributes inbound HTTP and HTTPS traffic among instances for even application load. Load balancers run at OSI layer 7 and use rules to configure routing to different target groups, redirecting to a different URL, and fixed HTTP response depending on specified conditions.

    To terminate HTTPS connections, the load balancer uses servers’ SSL certificates in X.509 format. When establishing a secure connection, TLS 1.0-1.3 protocols are supported. The load balancer decrypts the inbound traffic before sending it to the target resource.

Changes#

  • The new EFS service provides scalable and high-availability file storage that can be shared by multiple instances, including those in different VPCs and other networks outside the cloud. The EFS file system is accessed via Network File System (NFS) 4.1 protocol. To use the service, a user should be assigned the EFSFullAccess policy in a specific project.
