    **What is Eventarc?**\ \ **Eventarc** is a Google Cloud service that allows you to route events from various sources to your Google Cloud services in a standardized and efficient manner. It enables you to build event-driven architectures by capturing events from sources like Cloud Storage, Firebase, Pub/Sub, and other Google Cloud services, and then triggering workflows, Cloud Functions, Cloud Run, or other services based on those events. Eventarc simplifies the process of managing and responding to events across your cloud environment, making it easier to build scalable, loosely-coupled applications.

    **Enable required APIs** wizard will open, click on the **ENABLE** button
    5
    **Create trigger** wizard will open, give the Trigger name as - "**my-cloud-bucket-trigger"**

    **What is Trigger type : Google Sources?**\ \ **Trigger type: Google Sources** in Eventarc refers to a configuration option where events are generated by Google Cloud services. When you select this trigger type, you can set up Eventarc to listen for specific events from Google Cloud sources, such as Cloud Storage, Firestore, Pub/Sub, or other integrated Google services. These triggers enable you to automatically initiate workflows or processes in response to these events, like running a Cloud Function or starting a Cloud Run service.

    Scroll to the **Event provider** dropdown section, here you can select the Event provided as per your requirement
    information ordinal icon
    **What is Event provider?**\ \ An **Event Provider** in Google Cloud refers to the source of events that can trigger actions in services like Eventarc. These providers generate events based on specific actions or changes in their systems. For example, Google Cloud Storage is an event provider that can emit events when a file is created, deleted, or modified. Event providers supply the data that is used to trigger workflows, functions, or other responses in an event-driven architecture.

    **What is the option beta.compute.address.delete under the Event type dropdown section?**\ \ The option `beta.compute.address.delete` under the **Event type** dropdown in Google Cloud refers to a specific event that triggers when an IP address resource is deleted in the Compute Engine (during the beta phase of this feature). When this event type is selected in a service like Eventarc, it allows you to respond to the deletion of an IP address by executing a predefined workflow, such as invoking a Cloud Function or initiating another service. This is useful for automating tasks or maintaining records when specific resources are modified or removed in your cloud environment.

    Scroll to the **Event data content type** dropdown section and select the option **application/json** **Note:** You can select the option as per your requirement.
    10
    Scroll to the **Resource** section and select the option **Any resource** **Note:** You can select the option as per your requirement.
    information ordinal icon
    **What is the option Any resource under Resource section?**\ \ The **"Any resource"** option under the **Resource** section allows you to select all resources within the specified event type. This means that the event trigger will apply to any resource of that type, without limiting it to a specific resource name or ID. It's useful when you want to set up a trigger that listens for events across all resources of a certain kind in your project.
    11
    Scroll to the **Region** section and select the region close to your location
    information ordinal icon
    **What is Region?**\ \ In Google Cloud, a **region** is a specific geographical location where cloud resources are deployed and managed. Each region consists of multiple isolated locations known as zones. Regions allow you to deploy your applications and services closer to your users, which can improve performance and meet data residency requirements. Additionally, using multiple regions can enhance availability and resilience by distributing resources across different geographical areas.
    12
    Scroll to the Service account section, here you can select the Service account for the Eventarc
    information ordinal icon
    **What is the Compute Engine default service account?** The **Compute Engine default service account** is a special service account automatically created by Google Cloud for each project. This account is used by default to grant permissions to virtual machine (VM) instances in Google Compute Engine. It allows VMs to access other Google Cloud services and resources, such as Cloud Storage or BigQuery, without requiring you to manually configure authentication.
