Introduction Clustering allows an application running on Telidos Platform to run on several parallel servers (cluster nodes). The load is distributed across different servers, and even if any of the servers fail, the application is still accessible via other cluster nodes. Clustering is crucial for scalable enterprise applications, as you can improve performance by simply adding more nodes to the cluster. Why Clustering? Clustering solutions usually provide: Scalability High... [Read More]
