Overview
JFrog services can be configured for High Availability with a cluster of 2 or more active/active nodes on the same Local Area Network (LAN).
An HA configuration provides the following benefits:
Optimal Resilience
Maximize your uptime. In case one or more nodes is unavailable or down for upgrade, the load is shared between the remaining nodes, ensuring optimal resilience and uptime.
Improved Performance with Load Balancing
Scale your environment with as many nodes as you need. All cluster nodes in an HA configuration are synchronized, and jointly share and balance the workload between them. When a node becomes unavailable, the cluster will automatically spread the workload across the other remaining node(s).
Managed Heavy Loads
Accommodate larger load bursts with no compromise to performance. With horizontal server scalability, you can easily increase your capacity to meet any load requirements as your organization grows.
Always being Synchronized
Seamlessly and instantly synchronized data, configuration, cached objects and scheduled job changes across all cluster nodes.
HA Architecture
The HA architecture consists of 3 building blocks: load balancer, application(s) and common resources.
Getting Help
JFrog support team is available to help you configure the JFrog service's cluster nodes. It is up to your organization's IT staff to configure your load balancer, database and object store.
Load Balancer
The load balancer is the entry point to your JFrog Platform Deployment and optimally distributes requests to the nodes in your system. The load balancer is only required for the Artifactory service, which is then responsible to route and balance between the nodes of the other services. For additional information refer to Configuring Load Balancer.
Application
A JFrog service (or application) running in HA mode represents a cluster of two or more nodes that share common resources.
- All JFrog services (Artifactory, Xray, Mission Control, Distribution) can be run in HA mode, though only Artifactory requires a load balancer.
- Each cluster node runs all microservices, described in the System Architecture.
Common Resources
Each service requires a set of common resources. The resources vary per service but typically include at least one database.
Local Area Network
To ensure good performance, all the components of your HA installation must be installed on the same high-speed LAN.
In theory, HA could work over a Wide Area Network (WAN), however in practice, network latency makes it impractical to achieve the performance required for high availability systems.
