Hello everyone, We are currently using Kolla-Ansible stable/2024.1 to manage our OpenStack deployment, including both core services and the Swift object storage backend. Our goal is to manage all OpenStack services, including object storage, through a unified lifecycle management tool. We understand that managing large volumes of data can affect the performance of other services. To address this, we've separated the data flow entry points that could become bottlenecks into dedicated host groups: a load balancer and a Swift proxy. Specifically, we've created two separate host groups: one for the secondary load balancer (which serves as the initial entry point) and another for the Swift proxy services. 🔹 Key Point 1: Decoupling Swift Traffic We’ve separated the Swift proxy nodes from the other OpenStack API services. This also means that the load balancer handling Swift traffic must be distinct from the main load balancer used for services like Nova, Glance, and Neutron. 🔹 Key Point 2: Keystone Endpoint Behavior Swift still registers with the existing Keystone service. Depending on the configuration: - If the second_loadbalancer is enabled, Keystone publishes the VIP (Virtual IP) of the secondary HAProxy as the Swift endpoint. - If it’s disabled, Keystone uses the direct API address of the Swift proxy node. 🔹 Key Point 3: Two Supported Configurations Kolla-Ansible supports two architecture models for Swift: Normal and Advanced. - Normal Configuration This is the default setup in stable/2024.1, where all OpenStack services, including Swift, share the same load balancer and traffic path. - Advanced Configuration This is recommended for large-scale deployments with heavy data volumes. In this setup, Swift traffic goes through a dedicated load balancer and proxy nodes, which reduces contention and improves performance. We’d love to share this approach with the community and welcome any feedback or suggestions. Our goal is to make managing both compute and storage services within a single deployment framework as simple as possible. Thanks in advance for your insights!
