Amazon EventBridge
Amazon
Amazon EventBridge is a serverless event bus that makes it easy to connect applications together using data from your own applications, integrated Software-as-a-Service (SaaS) applications, and AWS services. EventBridge delivers a stream of real-time data from event sources, such as Zendesk, Datadog, or Pagerduty, and routes that data to targets like AWS Lambda. You can set up routing rules to determine where to send your data to build application architectures that react in real time to all of your data sources. EventBridge makes it easy to build event-driven applications because it takes care of event ingestion and delivery, security, authorization, and error handling for you. As your applications become more interconnected through events, you need to spend more effort to find events and understand their structure in order to write code to react to those events. -

IBM MQ
IBM
Massive amounts of data move as messages between applications, systems and services at any given time. If an application isn’t ready or if there’s a service interruption, messages and transactions can be lost or duplicated, costing businesses time and money to make things right. IBM has expertly refined IBM MQ over 25 years on the market. With MQ, if a message can’t be delivered immediately, it’s secured in a queue, where it waits until delivery is assured. Where competitors may deliver messages twice or not at all, MQ moves data, including file data, once — and once only. Never lose a message with MQ. IBM MQ is available as software to run in public or private clouds, in containers or on your mainframe. IBM also offers an IBM-managed cloud service (IBM MQ on Cloud) hosted on IBM Cloud or Amazon, and even as a purpose-built Appliance (IBM MQ Appliance) to simplify deployment and maintenance. -

Security product companies have huge need to build connectors with third party applications. This need is driven by multiple factors such as Customer requirement, enhance product capabilities etc. Target systems can be present on cloud, on-premise, hybrid environment. Complexities are added in terms of the varied options offered by Target systems such as interfaces available to integrate (REST API, SOAP, SFTP, Message Queue, SNMP, SDKs etc.). Data types (JSON, Syslog, File system, XML, etc.). Authentication and authorization options (OAuth, API Token, Username/Password, OTP, MFA, SAML, etc.). Rate limit, pagination, latency, concurrency, and data volume. Security Product Companies end up writing customized, non-standardized Connectors for these Target systems. This leads not only to increased development and support cost but also less efficient Connectors in terms of performance, scalability and extensibility.
