Some of the

most common outdated technologies in Java applications are:

?Synchronous HTTP: Current best practices are to almost always

use asynchronous HTTP requests. Synchronous HTTP requests are

disfavored because they block the client until the operation is complete,

wasting valuable computation time.

? Java Messaging System (JMS): Developers now prefer to work with

modern, high-performance messaging solutions such as Kafka or

ZeroMQ.

? Java Database Connectivity (JDBC): JDBC is oriented for use with relational

database management systems (RDBMS). However, many

developers currently favor NoSQL for their web applications.

? J2EE containers: Nowadays, developers tend to use modern asynchronous

HTTP engines.

This unwillingness to stay current is dangerous and potentially fatal for

organizations. Using outdated enterprise applications may feel like slipping

into a comfortable pair of shoes, but it puts you at risk for unexpected

behavior and events. For one, older technology — especially incredibly

popular technology such as Java — is more vulnerable to security risks

and cyber attacks that can bring your organization to a standstill.

Naturally, there’s also the simple fact that older technology makes you

less competitive against your rivals in the constantly changing business

landscape. It becomes harder to hire technical people who understand

how the older software works together. Meanwhile, it’s easier to hire talent

willing and able to bring applications up to date with modern technologies.

To avoid this fate for your organization, it’s your obligation to keep abreast

of the most crucial and common Java performance issues. By doing

so, you’ll be able to minimize their impact and even prevent them from

happening in your application.
