While the diagram illustrates a three-zone deployment, the VPC can also be provisioned in a single-zone or two-zone configuration, depending on your availability requirements.<br><br>The default configuration deploys a VPC with three zone subnets, configures the predefined ACLs, and attaches a public gateway with one of the subnets. You can also configure additional functionalities such as VPN gateway, VPE gateway, Flow Logs, security groups, etc. can be configured by providing the appropriate input values.<br><br>VPC Flow Logs are used to monitor and analyse traffic. To enable VPC Flow Logs, this solution automates the following tasks:<br>- Provisions a Cloud Object Storage (COS) instance using the COS deployable architecture. You can also use an existing COS instance.<br>- Creates an object storage bucket to store flow logs in the provisioned or existing COS instance.<br>- Supports creation of keys for a Key Management Service (KMS) if a KMS-encrypted bucket is enabled for enhanced security. You can use an existing KMS instance or create a new Key Protect instance using the KMS deployable architecture.<br><br>You can opt to integrate with <b>Observability services</b> to enable robust monitoring and logging capabilities to deliver deep operational insights into your VPC deployment. These services are <br> [IBM Cloud Activity Tracker Event Routing](https://cloud.ibm.com/catalog/7a4d68b4-cf8b-40cd-a3d1-f49aff526eb3/architecture/deploy-arch-ibm-activity-tracker-918453c3-4f97-4583-8c4a-83ef12fc7916-global) to monitor how users and applications interact with the VPC, supporting compliance and auditability.<br>[Cloud Logs](https://cloud.ibm.com/catalog/7a4d68b4-cf8b-40cd-a3d1-f49aff526eb3/architecture/deploy-arch-ibm-cloud-logs-63d8ae58-fbf3-41ce-b844-0fb5b85882ab-global) to collect, view, and analyze platform logs related to the VPC components.<br>[IBM Cloud Monitoring](https://cloud.ibm.com/catalog/7a4d68b4-cf8b-40cd-a3d1-f49aff526eb3/architecture/deploy-arch-ibm-cloud-monitoring-73debdbf-894f-4c14-81c7-5ece3a70b67d-global) to capture essential metrics such as CPU and memory utilization, helping you proactively monitor system performance and resource consumption.<br><br>This modular design provides flexibility and serves as a secure baseline for deploying compute workloads."
