Building Resilient Applications
April 22, 2016 | DiffusionData
Many of our objectives here at Push are intended to improve the stability and resilience for applications. An objective shared by the Reactive Manifesto:
“[Resilient Apps remain] responsive in the face of failure. This applies not only to highly-available, mission critical systems — any system that is not resilient will be unresponsive after a failure. Resilience is achieved by replication, containment, isolation and delegation. Failures are contained within each component, isolating components from each other and thereby ensuring that parts of the system can fail and recover without compromising the system as a whole. Recovery of each component is delegated to another (external) component and high-availability is ensured by replication where necessary. The client of a component is not burdened with handling its failures”.
Achieving resilience requires a broader understanding of your data, your application, and your users. Ultimately, applications designed to deliver innovative, engaging and differentiating product experiences can be left floundering if performance and stability is compromised.
At Push we see three fundamental components for application resilience.
As we discussed, data efficiency is the foundation to reliable and resilient application architecture. Push Technology’s delta streaming technology guarantees data is delivered as efficiently as possible, and implements a unique data optimization mechanism that sends only binary deltas. Reducing demands for both network and application resources.
With users, applications and devices in constant motion – or subject to variable network conditions – data delivery needs to be optimized and reliable even when the internet is not. Our real-time messaging products intelligently manage each connection, ensuring only the latest, relevant messages are delivered when a device reconnects to an active session.
In many environments, backend systems can’t sustain the load most mobile and IoT applications demand – this can result in failures that make your products unusable. Push Technology provides a live data cache at the edge of the network, ensuring that even when systems fail, your applications still have access to the last known data and continue to serve user requests.
Efficiency, reliability and availability are the trifecta for app resilience – and choosing the right real-time data integration solution can ensure your application architecture performs. With Diffusion Cloud or Diffusion – and our unique approach to streaming data – your apps can deliver even when other systems can’t.
