Java: The Backbone of Scalable Websites

I will be exploring some real world examples of java programming in this post. Two major users of java that affect and impact a lot of us ever day would be companies like LinkedIn and Amazon. Both of these extremely successful companies use Java programming for their back-end infrastructure and systems.

LinkedIn,

LinkedIn uses Java extensively to make up its back-end. Because of its massive user base it requires high scalability to manage features like real-time notifications and frequent feed updates. Java's multi-threading capabilities and robust libraries allow LinkedIn to handle the millions of user requests they get simultaneously.

LinkedIn uses Kafka, a distributed event streaming platform built with Java. It is used to process and deliver real-time data across the platform.

The use of the Java computing language is essential, Java's "Write Once, Run Anywhere" philosophy ensures that a program written in java is able to run on any device / system with a Java Virtual Machine. This helps tremendously in supporting a variety of client / user platforms, such as web browsers, mobile devices and other systems.

Extensive Library Support,

The extensive Library Support of of java is also very appealing. The vast libraries and frameworks simplify development at multiple levels. Some examples of these are:

Spring Boot - Framework used for building micro services and web apps.

Hibernate - For managing databases with Object Relational Mapping.

Apache Commons - Utility library used for file handling and data structures.

Concurrency APIs - For Creating multi-threaded applications and handling user requests in systems like LinkedIn.

Amazon,

As one of the biggest E-Commerce platform, Amazon's use of Java goes to prove its effectiveness. It uses Java for its back-end systems in order to provide its users with a smooth experience, as well as its high reliability. The main uses would be in their order processing, inventory management and payment gateways, as Java is very useful in building these distributed systems. In addition to this Java's scalability ensures smooth performances during times when they may experience alo of traffic, like Black Friday or other sales.

They also use Java-based frameworks for micro services and structure allowing different parts of the system independence in their operations.

These mentioned features show #java is an excellent choice for companies whether they are looking for performance or security.
