Running a real-time digital IT organization means high responsiveness, speed, and scalability.
Real-time applications may be designed with a distributed architecture, where different components (clients, servers, databases) are located across multiple systems and communicate in real time.
Scalable and Resilient Design: Real-time applications need to be able to handle sudden spikes in user activity and maintain high availability, often requiring a more scalable and resilient architectural design.
Communication Protocols: Computers and machines follow certain protocols to communicate between different interfaces.
-Real-Time Protocols: Real-time applications leverage protocols that enable low-latency, bidirectional communication, rather than relying on traditional request-response protocols like HTTP.
-Pub-Sub Model: Many real-time applications use a publish-subscribe (pub-sub) communication model, where clients subscribe to specific data channels or topics, and the server publishes updates to those channels in real time.
Data Management: Data management is the full cycle of data collection, storage, processing, and refining.
-Immediate Data Updates: Real-time applications need to ensure that data is immediately updated and reflected across all connected clients, rather than relying on periodic data refreshes or manual user actions.
-In-Memory Data Stores: Real-time applications may utilize in-memory data stores, such as Redis or Memcached, to enable fast data access and updates, as opposed to traditional disk-based databases.
Concurrency and Synchronization: Real-time application requires synchronization. -Concurrent User Interactions: Real-time applications must handle multiple users interacting with the system simultaneously, often with concurrent modifications to shared data.
-Synchronization Mechanisms: Real-time applications employ various synchronization mechanisms, such as locks, semaphores, or optimistic concurrency control, to ensure data consistency and prevent race conditions.
Performance and Scalability: Real-time business systems need to scale up and down accordingly.
-Low Latency: Real-time applications prioritize low latency and immediate response times, often with strict requirements for millisecond-level response times.
-Horizontal Scalability: Real-time applications need to be able to scale horizontally by adding more servers or instances to handle increasing user load, rather than relying on vertical scaling (upgrading a single server).
Error Handling and Resilience: From failing back to failing over, real-time applications have the right mechanism embedded into process management for error handling.
-Graceful Degradation: Real-time applications should be designed to gracefully degrade in the face of network failures or other disruptions, maintaining a functional user experience even when some features or data are unavailable.
-Fault Tolerance: Real-time applications often incorporate mechanisms for fault tolerance, such as redundant servers, load balancers, and failover strategies, to ensure high availability and reliability.
Running a real-time digital IT organization means high responsiveness, speed, and scalability. These architectural and implementation differences between real-time applications and traditional software reflect the unique challenges and requirements of building systems that need to respond instantly to user actions and events while maintaining high performance, scalability, and resilience.
