This architecture supports deployment of a Virtual Server Instance within an IBM Cloud Virtual Private Cloud (VPC) environment.

The VPC is hosted within a designated resource group in a specific region. You can either provision a new VPC or use an existing one, depending on your workload requirements. The VPC includes a subnet for network segmentation and connectivity of compute resources.

At the core of this setup is the Virtual Server Instance on VPC, which can be optionally associated with block volumes for additional data storage. These block volumes can be encrypted using key management services (KMS), where a boot-volume key is managed under a defined key ring.

To enhance secure access and centralized credential management, Secrets Manager can be integrated. This enables storage and retrieval of sensitive information such as ssh private keys, helping ensure secure and auditable server access.

For external connectivity, the architecture supports optional assignment of a floating ip to the virtual server, allowing public network access as needed.

A security group is defined to control inbound and outbound traffic to the virtual server. It includes a load balancer setup, consisting of a Load Balancer Listener, Load Balancer, and Load Balancer Pool to distribute traffic efficiently across backend resources.

Observability capabilities can be optionally enabled to monitor and manage the health and performance of deployed resources. This includes Cloud Monitoring for metrics and Cloud Logs for log aggregation and analysis.

This architecture provides a scalable, secure, and flexible foundation for deploying applications on IBM Cloud, integrating optional services such as encryption, observability, and secure key management for enterprise-grade workloads.
