Networking Capabilities on Cozystack

VPC

Mon, 01 Jan 0001 00:00:00 +0000

VPC offers a subset of dedicated subnets with networking services related to it. As the service evolves, it will provide more ways to isolate your workloads.

Service details

To function, the service requires kube-ovn and multus CNI to be present, so by default it will only work on paas-full bundle. Kube-ovn provides VPC and Subnet resources and performs isolation and networking maintenance such as DHCP. Under the hood it uses ovn virtual routers and virtual switches. Multus enables a multi-nic capability, so a pod or a VM could have two or more network interfaces.

Internally known as “Shadowbox”, which simplifies the process of setting up and sharing Shadowsocks servers. It operates by launching Shadowsocks instances on demand. Furthermore, Shadowbox is compatible with standard Shadowsocks clients, providing flexibility and ease of use for your VPN requirements.

Managed Nginx-based HTTP Cache Service

Mon, 01 Jan 0001 00:00:00 +0000

The Nginx-based HTTP caching service is designed to optimize web traffic and enhance web application performance. This service combines custom-built Nginx instances with HAProxy for efficient caching and load balancing.

Deployment information

The Nginx instances include the following modules and features:

VTS module for statistics
Integration with ip2location
Integration with ip2proxy
Support for 51Degrees
Cache purge functionality

HAproxy plays a vital role in this setup by directing incoming traffic to specific Nginx instances based on a consistent hash calculated from the URL. Each Nginx instance includes a Persistent Volume Claim (PVC) for storing cached content, ensuring fast and reliable access to frequently used resources.

Managed TCP Load Balancer Service

Mon, 01 Jan 0001 00:00:00 +0000

The Managed TCP Load Balancer Service simplifies the deployment and management of load balancers. It efficiently distributes incoming TCP traffic across multiple backend servers, ensuring high availability and optimal resource utilization.

Deployment Details

Managed TCP Load Balancer Service efficiently utilizes HAProxy for load balancing purposes. HAProxy is a well-established and reliable solution for distributing incoming TCP traffic across multiple backend servers, ensuring high availability and efficient resource utilization. This deployment choice guarantees the seamless and dependable operation of your load balancing infrastructure.

Virtual Routers

Mon, 01 Jan 0001 00:00:00 +0000

Starting with version v0.27.0, Cozystack can deploy virtual routers (also known as “router appliances” or “middlebox appliances”). This feature allows you to create a virtual router based on a virtual machine instance. The virtual router can route traffic between different networks.

Creating a Virtual Router

Creating a virtual router requires a Cozystack administrator account.
