*WSO2 Carbon Kernel 4.4.0 Beta 1 is Released!!!* WSO2 Carbon team is pleased to announce the first beta release of the WSO2 Carbon Kernel 4.4.0.
WSO2 Carbon redefines middleware by providing an integrated and componentized middleware platform that adapts to the specific needs of any enterprise IT project - on premise or in the cloud. 100% open source and standards-based, WSO2 Carbon enables developers to rapidly orchestrate business processes, compose applications and develop services using WSO2 Developer Studio and a broad range of business and technical services that integrate with legacy, packaged and SaaS applications. WSO2 Carbon kernel, the lean, modular, OSGi-based platform, is the base of the WSO2 Carbon platform. It is a composable server architecture which inherits modularity and dynamism from OSGi framework. WSO2 Carbon kernel can be considered as a framework for server development. All the WSO2 products are composed as a collection of reusable components running on this kernel. These products/components inherit all the core services provided by Carbon kernel such as Registry/repository, User management, Transports, Caching, Clustering, Logging, Deployment related features. *What's New In This Release* - Java7/Java8 support - the new kernel can now be compiled and run on both Java7 and Java8. - Tomcat upgrade - Tomcat is upgraded to version 7.0.59. - Tenant Eager Loading - WSO2 Carbon Kernel can now be configured to load specified set of tenants at server start-up. *Key Features* - Composable Server Architecture - Provides a modular, light-weight, OSGi-based server development framework. - Carbon Application(CApp) deployment support. - Multi-Profile Support for Carbon Platform - This enable a single product to run on multiple modes/profiles. - Carbon + Tomcat JNDI Context - Provide ability to access both carbon level and tomcat level JNDI resources to applications using a single JNDI context. - Distributed Caching and Clustering functionality - Carbon kernel provides a distributed cache and clustering implementation which is based on Hazelcast- a group communication framework - Pluggable Transports Framework - This is based on Axis2 transports module. - Registry/Repository API- Provide core registry/repository API for component developers. - User Management API - Provides a basic user management API for component developers. - Logging - Carbon kernel supports both Java logging as well as Log4j. Logs from both these sources will be aggregated to a single output - Pluggable artifact deployer framework - Kernel can be extended to deploy any kind of artifacts such as Web services, Web apps, Business processes, Proxy services, User stores etc. - Deployment Synchronization - Provides synchronization of deployed artifacts across a product cluster. - Ghost Deployment - Provides a lazy loading mechanism for deployed artifacts</li> - Multi-tenancy support - The roots of the multi-tenancy in Carbon platform lies in the Carbon kernel. This feature includes tenant level isolation as well as lazy loading of tenants.
