The first step in troubleshooting an IBM Cloud access issue is to ensure that the user has the appropriate permissions to access the service or service instance through Identity and Access Management (IAM). IBM Cloud uses IAM to manage user access to resources and services, and improper or insufficient permissions are a common cause of access issues.

Checking IAM Permissions:Users must be granted the correct roles and access policies within IAM to interact with specific IBM Cloud resources. This involves verifying that theuser has the necessary level of access (such as Viewer, Editor, or Administrator roles) for the service or resource in question.

Why IAM Access Matters:Without proper IAM access, users will be unable to view, modify, or delete resources, and access issues may manifest as permission errors, inability to see resources, or inability to interact with the service.

Comparison with Other Options:

A (Verify the ACLs):While ACLs are important, IAM access is the primary consideration in IBM Cloud.

B (Operator role):The Operator role may not necessarily grant sufficient access for all use cases.

D (Open a support case):This should be a subsequent step if IAM permissions are correctly configured.

For general-purpose applications in IBM Cloud, the recommendedIOPS tierwhen provisioning10 TB of Block Storage for Virtual Private Cloud (VPC)is3 IOPS/GB. This IOPS tier provides a balanced level of performance suitable for a wide range of general-purpose workloads, ensuring that the application can handle typical storage and performance requirements without unnecessary over-provisioning or cost.

The 3 IOPS/GB tier is designed to provide a reasonable level of input/output operations per second (IOPS) for general-purpose applications, such as web hosting, database hosting, or development workloads that do not require high-performance storage.

For more performance-critical or latency-sensitive applications, you might choose a higher IOPS tier (such as 5 or 10 IOPS/GB), but for general-purpose workloads, 3 IOPS/GB offers an optimal balance between cost and performance.
