While building platforms and cloud based applications product teams face challenges such as:
- Availability – Using multiple linked services instead of a single application. Again, each of these services have to work flawlessly 24×7.
- Scalability – While availability makes sure that at least one instance is running to service any requests, scalability is more focused on performance under higher load.
- Synchronous – In a typical request-response scenario, the user has to wait for the server and then respond. It tends to block all activities until the timeout expires or until a response is served.
An event-driven architecture is a system of a couple of microservices that exchange information between each other through consumption and production of events. It’s a simple system wherein a message is generated to be distributed over an event-driven ecosystem. After that, it broadcasts them to services interested in receiving them.
Approaches to upgrading an application:
To make a software scalable and serviceable, it is wise to select an architecture wherein the services and functions are independent. It’s one of the driving factors for changing from monolith to microservices based architecture.
For creating scalable software needs to be deployed on multiple instances, it’s recommended to modernize the apps with microservices architecture. So, updating the architecture should be the right step when upgrading the product or application.
One of the promising aspects of event driven architecture is that it fits perfectly for enterprise applications that tend to send/receive data from real-time and scalable communication from data integration, website activity, and mobile application users.
What does event-driven architecture deliver?
There’s lot of tangible business advantages when moving applications to event-driven architecture:
- Real-time speed – It enables the users to get data real quick and in real-time. Event-driven architecture also makes it easy to maintain connectivity with external partners, stakeholders, consumers, and suppliers using APIs.
- Low latency – Improve your application performance by accessing the data instantly. When using point-to-point integrations to share data, event-driven architecture can reduce latency to a fraction of a second.
- Helps in informed decision making – When there is real-time event processing, event-driven architecture helps to deliver critically, updated, and accurate information.
- Data scalability – Event-driven architecture helps to build highly scalable apps. It enables apps to handle massive amount of data without performance loss. Also, it provides flexibility to scale up or scale down depending on the business needs.
- Reliable operation – Event-driven architecture ensures reliable operation, communication, and mitigating service downtime.
With event-driven architecture, applications are asynchronous, allowing events to be processed later if the service is busy or isn’t available. Moreover, the services are decoupled in the event-driven architecture model. So, if a service goes down, it doesn’t impact end users.
Event-driven architecture one of the preferred methods of our software specialists and architects to upgrade a product or application for user success.
