The latest version of enterprise Java infrastructure software Terracotta server supports cross-application data sharing and grid-enabling APIs. Terracotta development team recently announced the availability of Terracotta server 3.0 version. The new version also provides operations center and developer consoles for server monitoring and an updated cluster membership API.
Terracotta 3.0 server supports a memory based data management solution in contrast to the relational database by managing application data and transactions in-memory, in object form, to help with the application performance and scalability. The new features in the latest version include:
Server Array Striping:
Terracotta 3.0 introduces the updated version of the Server Array Striping technology which allows Terracotta to deliver better throughput for the Java applications while offloading from the database of redundant reads and writes.
Operations Center Console:
The server utilizes the in-memory data management feature to provide a new Operations Center user interface for the IT operations team. The console includes an operations dashboard, system diagnostics, system backup, systems management and a cluster-wide log viewer.
Developer Console:
A new Developer Console provides a task-organized view of performance metrics, the data in memory for debugging purposes, and to visualize detailed runtime statistics.
Cross-Application Data Sharing:
The application sharing feature can be used to share clustered data between different applications running in an application server. This feature can be enabled by a configuration change without any changes to the existing application code. The benefits from sharing Terracotta roots across applications include allowing a remote monitoring application to view the current shared state of multiple applications and providing the application state to user sessions interacting with two or more applications.
Cloud and Grid-Enabling APIs:
There are new APIs to simplify the application deployment and improve the performance of web applications deployed in cloud and grid environments. Terracotta's data routing, data presence, and cluster membership APIs can be used to find and move data where it needs to be, simplifying fault-tolerant operations of grid applications.
Updated Cluster Membership Events:
Cluster Events API provides the information about the nodes joining the cluster, nodes leaving the cluster, and when cluster operations are disabled (e.g. during a failover event) and when they are re-enabled. The Terracotta cluster membership events can be injected using IoC frameworks like Spring or Guice.
Terracotta 3.0 server also supports WebLogic Server 10.2 and 10.3 versions (including HTTP Session replication) and the open-source systems management provider Hyperic HQ.
