JVM Monitoring and Performance Assurance for Java-Based Banking and Trading Applications
Java is one of the most popular technologies used for application development. Tens of thousands of web and mobile applications are built on Java around the world. Some highlights of Java’s advantages include its security, scalability, portability and compatibility – among the most sought characteristics for building highly demanding and performance-sensitive applications, as seen in banking, trading, and other financial corporations. Speed is absolutely critical for these low-latency applications. If a Java-based trading application is not able to manage handling large in-memory data sets in real time, business-critical transactions will stall. Just a few milliseconds of delay can be disastrous and result in heavy financial losses.
The role of the Java Virtual Machine (JVM) in Java’s server-side architecture plays a major role in memory management for these high-frequency applications. Using a process known as garbage collection, the JVM automatically frees up heap memory used by objects that are no longer referenced in the Java code. Automating this process makes the life of a developer easier, as he/she is relieved from keeping track of free allocated memory, a time-consuming task. However, garbage collection does itself take time to execute. The more frequently it happens, the more pauses will occur in processing data. So, with too much garbage collection the transaction will likely suffer from slow performance.
Conventional JVM manufacturers are working towards reducing garbage collection pauses and ensuring that memory management is more seamless, using techniques such as concurrent, parallel and compacting garbage collection. Further, some modern JVM vendors, such as Azul, are adopting a radically new pauseless approach to garbage collection that delivers faster processing for low-latency and memory-intensive applications.
