Increase Default VPC Security Group Rule Quota from 250 to 500

Current Behavior

IBM Cloud VPC currently limits Security Group Rules to 250 by default. Customers that exceed this limit must submit a support request for a quota increase.

Problem

The current limit is becoming a frequent blocker for customers running modern enterprise workloads, including microservices-based applications and SAP HANA environments.

Recent case trend analysis identified Security Group Rule quota increases as one of the most recurring VPC quota requests. Multiple customers have experienced deployment and automation pipeline failures after reaching the 250-rule limit, requiring urgent quota increase requests to proceed.

In addition, staging and test environments generate recurring bulk quota requests, increasing operational overhead for customers, support, and engineering teams.

Proposed Solution

Increase the default Security Group Rule quota from 250 to 500.

Who Would Benefit

• Enterprise VPC customers

• SAP HANA deployments

• Kubernetes/OpenShift and microservices-based workloads

• Customers with complex network segmentation requirements

• IBM Cloud Support and Operations teams through reduced quota-related ticket volume

How It Should Work

• Increase the baseline default Security Group Rule quota from 250 to 500 for new and existing accounts.

• Continue to allow higher limits through the existing quota management process where required.

• Optionally, provide a self-service quota increase path for eligible accounts to reduce dependency on support cases.

Business Value

• Reduces recurring quota increase requests.

• Prevents deployment and automation failures caused by quota exhaustion.

• Improves customer experience and onboarding.

• Lowers operational overhead for Support, Operations, and Engineering teams.

• Better aligns default quotas with modern cloud-native and enterprise workloads.
