Event-Driven
Unlock greater scalability, fault tolerance, and developer velocity by decoupling your application components.
Traditional monolithic architectures can create roadblocks—slow response times, limited flexibility, and more downtime—that can slow innovation and hinder your ability to stay competitive. With EDA, we can help you overcome these obstacles by building scalable, resilient applications that quickly adapt to changes.
What is EDA?
EDA is a modern architectural approach that focuses on events—significant occurrences that indicate changes within a system. It enables different services and components of your infrastructure to communicate by reacting to these events.
With EDA, you can decouple services, allowing them to evolve and scale independently, without disrupting the rest of your business operations.
Benefits
- Cost-Efficiency: Instead of overhauling your entire system, EDA allows you to integrate events from legacy systems, enabling gradual modernisation. This approach lets you add new features and functionalities incrementally, without requiring significant upfront investments.
- Agility & Innovation: EDA empowers you to innovate quickly by developing and deploying new services independently of existing systems. This decoupling allows you to roll out new features, products, and updates faster, reducing development time and minimising the risk of service disruption.
- Fault Tolerance & Scalability: EDA ensures your system can handle spikes in demand and unexpected failures seamlessly. Built-in fault tolerance and event buffering keep services running smoothly, even when part of the system encounters issues. This leads to reduced downtime, improved resilience, and a better customer experience.
- Real-Time Insights: Unlike legacy systems that rely on batch processing, which often results in outdated analytics, EDA processes events in real-time. This provides immediate insights, enabling faster, data-driven decision-making. By eliminating delays from periodic reports, you can respond more quickly to changing conditions and opportunities.
How EDA Works for You
- Integrating Diverse Technology Stacks: Whether your systems are built on legacy platforms or modern cloud-native solutions, EDA allows for frictionless data exchange across all platforms, making integration easier and reducing complexity.
- Cross-Region, Cross-Account Data Replication: If your infrastructure spans multiple AWS regions or accounts, EDA ensures smooth data synchronisation and event routing across all systems, so your teams can scale and deploy services independently while maintaining reliable data consistency.
- Observability: With EDA, you can automate the monitoring of your resources. Real-time alerts inform you about any changes or issues, allowing your team to address problems before they escalate and ensuring smoother operation.
- Fanout and Parallel Processing: EDA makes it easier to distribute events across multiple systems without custom coding for each. The event router pushes the event to all relevant services, allowing parallel processing and reducing the complexity of your infrastructure.
