A relevant architecture model for applications interacting in real time with users

With the explosion of mobile and data-driven applications, users are demanding real-time access to everything everywhere. System resilience and responsiveness are no longer "nice to have"; they're essential business requirements to meet modern demands. Businesses increasingly need to trade up from static, fragile architectures in favor of Responsive, Resilient, Elastic and Message-Driven systems. This system is known as Reactive System.

Reactive System fulfills modern resiliency requirements and easy to develop and amenable to change. They are significantly more tolerant of failure and when failure does occur they meet it with elegance rather than a disaster. Reactive Systems are highly responsive, giving users effective interactive feedback.

In a nutshell, Reactive Systems are

Knoldus Reactive System

The system responds in a consistent and timely manner if at all possible. It also detects problems quickly and mitigates them effectively.

Knoldus knoldus-resilient-icon


The system stays responsive in the face of failure. Resilience is achieved by replication, containment, isolation, and delegation.

Knoldus knoldus-elastic-icon


The system stays responsive under varying workload. Reactive Systems can react to changes in the input rate by increasing or decreasing the resources allocated to service these inputs.

Message Driven

Reactive Systems rely on asynchronous message-passing to establish a boundary between components that ensure loose coupling, isolation and location transparency. This boundary also provides the means to delegate failures as messages.

As an official Lightbend Partner, Knoldus maintains a proven track record of successfully integrating scalable, fault-tolerant solutions for our customers by implementing the Reactive system using Scala, Spark, Lagom, Akka, Kafka, and Play Framework. Leverage our expertise to build modern, Reactive systems that meet the performance, scalability, and reliability needs of today's cloud-native applications.
