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most common outdated technologies in Java applications are: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 Using outdated enterprise applications may feel like slipping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.
