Deploying & Managing Java Applications in the Data Center
Java is one of the most popular technologies for modern business and web applications. As you are most probably aware, many diverse and distributed components work in orchestration to deliver the final application. Components such as web servers (e.g. Tomcat), web application servers (e.g. Websphere, Weblogic, JBoss), databases, JMS, JMX, and configurations files (e.g. ini, properties files, xml) to name a few. When deploying and maintaining Java applications in your data center - it's critical to synchronize and configure your application components. Typically, your release flow will have the following attributes:
- WAR and EAR distribution to many servers and even across data centers.
- Stopping and starting Tomcat, JBoss, Websphere and other services.
- Updating config files including changing and adding XML parameters.
- Backing up existing file structures and directories.
- Running SQL queries before, after, and even during updates.
- Removing and adding servers to the load balancer pool.
- Deleting cache files and folders.
- Activating JMX for managing application pools, reloading files, etc.
- Validating deployment with file checksums, HTTP requests, log validation, etc.
If you are responsible for overseeing Java application releases, deployments, and maintenance, whether you're a part of IT Operations, DevOps, or Application Delivery, then you recognize the complexity of orchestrating such activities, and how manual and scripted approaches are both error prone and non-scalable.
Nolio for Java Deployment
With Nolio ASAP (Application Service Automation Platform) you can create complex workflow processes for releasing, deploying, and managing, any of your Java, J2EE, JBoss, and other Java middleware applications.
We took an example from one of our customer's who has an online finance application. Serving hundreds of banks, their application is running Java with an Oracle database. When configuration changes need to be rolled out to hundreds of servers, a simple Nolio process is used, that also restarts services and ensures that the upgrade deployment was successfull.
