Configuration for
Tomcat/TomEE Cluster

The network architecture features a load balancer and session replication. At the top, two green cubes represent servers within the load balancing system, with multiple horizontal lines indicating data flow. Below, three orange icons labeled Node 1, Node 2, and Node N signify the application servers, with the "N" indicating scalability for an unlimited number of nodes. Red two-way arrows connect the nodes, highlighting session replication, which ensures session data is consistently synchronized across all nodes. This setup demonstrates efficient load distribution while maintaining session integrity across the system.

Configuration for Tomcat/TomEE Cluster

Technical Highlights of Tomcat
TomEE Auto-Clustering

DeltaManager for Session Replication

Tomcat’s DeltaManager component ensures that user session changes are detected and synchronized across all nodes in the cluster. This guarantees consistency in user experience, even in multi-node environments.

TCP-Based Communication

The Tomcat cluster uses TCP protocol for communication between nodes. The default port is configured to allow smooth data transfer and firewall rules are automatically set to ensure secure connections.

Interceptors and Failover Detection

The configuration includes various interceptors like TcpFailureDetector, which ensures quick identification of failed nodes, and MessageDispatchInterceptor, which manages the asynchronous transfer of messages across the cluster.

Static Membership for Node Discovery

Cluster nodes are identified using static membership, meaning that all node IPs and unique IDs are preconfigured and listed in the server.xml file on each node.

Tomcat Cluster Key Features

Cluster Management

The SimpleTcpCluster class handles the core operations of the cluster, ensuring communication between nodes is smooth and efficient. This helps maintain the overall health of the cluster by coordinating activities like node communication and failure recovery.

Multicast Membership

A multicast address is used to share data between nodes, ensuring that all nodes stay updated with the latest session and server states. This keeps the cluster synchronized and allows for real-time updates.

Thread Management

The Receiver and Sender components control the flow of data between nodes. The NioReceiver ensures high efficiency when receiving messages, while the PooledParallelSender enables concurrent message sending, improving overall communication speed and performance within the cluster.

Benefits of the Tomcat/TomEE
Cluster Solution

Simplified Configuration

The clustering setup process, including configuration of the server.xml and context.xml files, is fully automated. This drastically reduces the time and complexity involved in creating a high-availability environment.

Performance Optimization

The cluster is configured to handle large volumes of requests efficiently, distributing traffic across multiple nodes while replicating session data in real-time.

Seamless Horizontal Scaling

The cluster automatically scales up or down based on the traffic load, preventing performance bottlenecks and resource wastage.

Zero Downtime Deployment

Automatic failover and session replication ensure zero downtime, even during node failures.

True Consumption-Based Pricing

When using AccuWeb.Cloud, your payment is determined by your actual usage rather than the size of your server.

The system makes hourly measurements of how many RAM and CPU resources are being used on each container and requests payment only for these used resources. You can set up a maximum Scaling Limit for each container, so the resources will always be available in case of load spikes or other consumption changes. No matter how high the limit – the payment will only be based on actual usage.
