This video shows how to take an existing JavaEE 6 application and presents the complete life cycle of taking this application from desktop to a PaaS environment. It details how JavaEE containers such as GlassFish can provide such service orchestration and elasticity capabilities, explaining the development, testing and debugging of such an application in the PaaS environment.

Relational databases have long been considered the one true way to persist enterprise data. But today, NoSQL databases are emerging as a viable alternative for many applications. They can simplify the persistence of complex data models and offer significantly better scalability, and performance. But using NoSQL databases is very different than the ACID/SQL/JDBC/JPA world that we have become accustomed to.

These two videos provides an overview of the CumuLogic PaaS offering. CumuLogic’s product is a private Platform-as-a-Service (PaaS) for both public and private clouds. CumuLogic PaaS provides a cloud-based application management framework to simplify the deployment and management of the entire application lifecycle in private and public clouds.

This initial video explains the the mismatch between object and relational models and what Object/Relational Mapping (ORM) is. ORM is the concept that Hibernate uses to facilitate the storage and retrieval of Java domain objects in relational databases.

The needs of many enterprises have stretched traditional RDBMS based solutions to the breaking point and as a result, a plethora of new non-relational storage options have appeared: key-value stores, column storages, document and graph databases.

This video presents what the combination of MongoDB and Cloud Foundry has to offer to Spring developers. A sample applications is developped to show how to build and deploy to the cloud. You will also see how to connect to the MongoDB service bound to the application in the cloud. This provides the ability to import and export data and to run ad-hoc queries from a command line tool.

In the Java world, Not-only-SQL (NoSQL) systems can be applied in a large number of problem domains. In general, it’s safe to say that NoSQL is a contender against traditional RDBMSs if data storage and retrieval needs aren’t transactional.
