Future of Event-Driven Architectures with Oracle HCM Event Hubs
The future of Event-Driven Architectures with Oracle HCM Event Hubs is promising with Immediate Actions for Anomalies and Changes in Storage Buckets and Throughput Units for Processing Events, as supported by the Reference Data. Get ready to explore the powerful benefits and potential for innovation with Oracle HCM Event Hubs.
Immediate Actions for Anomalies and Changes in Storage Buckets
Storage buckets are key parts of event-driven architectures. Taking quick action to anomalies and changes in these buckets can stop unexpected system stoppages that can happen if something fails. Oracle Cloud Infrastructure has a six-step guide using their Event Hubs service.
- The first step is to turn on alert notifications to get messages when files are added or taken away from storage buckets.
- Step two is to keep spare capacity and reduce traffic to stop floods that can cause system overload.
- Step three is to make data retention policies to decide how long data is useful before putting it in the archive or deleting it.
- Step four is to use analytics dashboards to measure how well applications are working based on how fast they process, how long it takes, and read/write rates.
- Step five is to use the TU pricing model to guess usage costs based on SLAs.
- Finally, step six is to use automated event processing services without needing resource provision or management overheads.
For event-driven architectures to work, you have to take quick action to mutations of files in storage buckets. Oracle Cloud Infrastructure has orchestration services such as Event Hubs for automated responses. Events arrive and are processed straight away at the Hub Connectors for real-time notification alerts with faster latencies than normal mail clients.
A practical tip to make startup times faster with bootstrapped credentials for permissions and security practices within structured streaming with Azure Event Hubs is to limit the initial amount of logged data per session during setup so that you can see events showing up in a semantic way instead of regulatory info.
Throughput Units for Processing Events
Processing big volumes of events? Developers need something that can manage data streams without any hiccups. That’s where Oracle HCM Event Hubs come in. They give Throughput Units (TUs) to help developers optimize event processing and ensure smoother data movement.
To make the right decision, there’s a table that shows all the TU levels and their related performance metrics. These levels range from 1TU, which can handle 100 events/second and a max peak traffic of 2 Mbps, to 40TUs, which can handle up to 4,000 events/second and 80 Mbps peak traffic. There’s even a Custom TU option that has performance metrics based on specific needs.
It’s important to remember that TUs don’t depend on the number of events, but on the level chosen. The size and complexity of incoming event payloads will affect the output performance.
A financial services company used Oracle HCM Event Hubs with custom TU levels to process millions of events within risk management applications. This implementation saved money and increased efficiency in event processing, thanks to the high system availability and low latency offered by the platform.
To sum it up, selecting the right TU level is key for developers who want their event streams to be processed perfectly. Oracle HCM Event Hubs provide a reliable solution that fits businesses from different industries.
We’re done! It’s plain to see that event-driven architecture is now a major hit for companies hoping to better their HR processes. Oracle HCM Event Hubs provide cloud-based streaming platforms to manage data quickly in real-time. This lets HR teams act fast when there are changes to employee data, training, and reviews.

This left the HR team more time to take on other tasks like employee engagement and talent development.
To sum up, event-driven architecture with Oracle HCM Event Hubs is great for optimizing HR processes, responding quickly, and creating an agile, competitive environment.
FAQs about Event-Driven Architecture With Oracle Hcm Event Hubs
What is event-driven architecture?
Event-driven architecture (EDA) is a software design pattern where microservices react to changes in state, called events. Events can carry state or be identifiers and trigger microservices to work together towards a common goal. Each microservice can apply different business logic and emit its own output events. Events are records of immutable facts that can be persisted indefinitely and consumed multiple times.
How can Oracle Cloud Infrastructure help with event-driven architecture?
Oracle Cloud Infrastructure allows for building event-driven applications that respond in near real-time to changes in cloud resources and application-generated events. Events in the cloud refer to significant occurrences or changes in a system, and event-driven architectures capture, communicate, process, and persist these events. Most modern apps built with microservices rely on an event-driven architecture, which can use either a publish-subscribe or event-stream model. Successful event-driven apps are flexible, scalable, secure, use consistent and deterministic deployment processes, and are simple to manage. Oracle Cloud Infrastructure provides the platform building blocks for deploying optimal event-driven apps, including a managed, cloud-based messaging service called Streaming.
What should I know about using Oracle Streaming for event-driven applications?
Oracle Streaming is a managed, cloud-based messaging service that provides a highly available and scalable platform for working with streaming data. It allows for the capturing, communication, processing, and persisting of events which are significant occurrences or changes in a system. Oracle Streaming can be integrated with streaming endpoints and functions in a private network for dynamic processing. Service connectors act as an interface between infrastructure events and accessible endpoints for streaming data or functions. Service connectors also send alerts and notifications that require immediate actions. Accessible endpoints handle application events for streaming data and pass them to functions in the private network. Functions in the private network direct alerts and notifications to trigger immediate actions and store processed messages in an autonomous database for further processing, storage, or analysis. Oracle Analytics Cloud can be used to visualize and gain insights from stored data at key stages of the event processing lifecycle.
What is the role of an event router in an event-driven architecture?
Event routers link different services and execute a response to the original event generated by a producer, sending the response downstream to appropriate consumers. In an event-driven system, events are generated by producers, ingested and filtered by a router, and then fanned out to appropriate consumers. The three components (producers, router, consumers) are decoupled and can be independently deployed, updated, and scaled.
How can Azure Event Hubs be integrated with Apache Spark Structured Streaming?
Azure Event Hubs is a scalable real-time data ingestion service that can receive large amounts of data from multiple sources and stream the prepared data to Azure Data Lake or Azure Blob storage. Apache Spark Structured Streaming is a fast, scalable, and fault-tolerant stream processing API that can perform analytics on streaming data in near real-time using SQL queries. Azure Event Hubs can be integrated with Spark Structured Streaming to process messages in near real-time and analyze the processed data using a Structured Streaming query and Spark SQL. The components of Azure Events Hubs include event producers, partitions, consumer groups, and throughput units.
What is the concept of Event-Driven Architecture in Service-Oriented Architecture?
Event-Driven Architecture (EDA) specifies how “services” are hooked into “business events” to trigger responses across an organization. EDA allows for the publishing of events from the process that creates or encounters them to a central event-handling backbone. The central backbone can be configured with a powerful tool such as Oracle ESB, but it is important to note that this service has been discontinued and will not be available after May 2023.
