Effective isolation requires consistent application across all three planes with regular audits of inter-plane dependencies.
Implement defense-in-depth with overlapping controls and automated enforcement where possible.

// Pattern data
const patterns = {
control: [
{
title: "Management API Isolation",
description: "Separate API endpoints, control services, or management consoles for different tenants, environments, or even different logical components.",
examples: [
"Cloud Providers: Separate IAM roles and policies for different accounts/projects, dedicated API gateways for management services, rate limiting on management APIs.",
"Kubernetes: RBAC applied to kubectl operations and API server access, separate control plane components (e.g., dedicated etcd clusters for critical services).",
"Multi-tenant SaaS: Admin dashboards or management APIs are tenant-aware and enforce strict authorization boundaries."
],
impact: "Prevents cross-tenant API abuse and ensures management plane robustness."
},
{
title: "Configuration Isolation",
description: "Ensuring that configuration changes for one component or tenant do not inadvertently affect others.",
examples: [
"Cloud: Separate S3 buckets for configuration files per environment/application, Parameter Store/Secrets Manager isolated per service.",
"Kubernetes: Separate ConfigMaps and Secrets per Namespace, or even per application within a Namespace.",
"Enterprise: Dedicated configuration repositories (Git) per application or team, with strict branching/merging strategies."
],
impact: "Avoids configuration drift and contamination between environments."
},
{
title: "IAM Isolation",
description: "Dedicated identity providers, user directories, or strict role-based access controls (RBAC) to ensure that users/services from one domain cannot assume identities or roles in another without explicit authorization.",
examples: [
"Cloud: Separate IAM users/roles/policies per AWS account, Azure subscription, or GCP project. Cross-account roles are explicitly configured.",
"Enterprise: Separate Active Directory forests or OIDC/SAML realms for different business units or security zones."
],
impact: "Foundation for least privilege access control."
},
{
title: "Scheduler Isolation",
description: "In distributed systems, the scheduler (e.g., Kubernetes scheduler) or orchestrator can be a shared resource. Isolating its operation means ensuring that scheduling decisions or orchestration tasks for one tenant/workload don't starve or negatively impact others.",
examples: [
"Kubernetes: Node taints and tolerations, pod anti-affinity, resource quotas at the Namespace level, PriorityClasses to ensure critical workloads get scheduled.",
"Distributed Schedulers: Resource managers (e.g., YARN in Hadoop) with fair schedulers or capacity schedulers that partition resources."
],
impact: "Prevents workload starvation and ensures fair resource allocation."
}
],
data: [
{
title: "Process Isolation",
description: "Each application or microservice runs in its own isolated process space, preventing memory corruption or unauthorized access between applications on the same host.",
examples: [
"Docker containers",
"Kubernetes Pods",
"OS processes with separate memory spaces",
"Separate JVM instances"
],
impact: "Prevents noisy neighbor issues and contains failures."
},
{
title: "Storage Isolation",
description: "Ensuring that one tenant's data in a shared storage system (database, file system, object storage) is logically and often physically separated from another's.",
examples: [
"Databases: Separate schemas, separate tablespaces, row-level security, separate database instances, sharding by tenant ID.",
"Object Storage: Separate buckets/prefixes per tenant, access policies on objects.",
"Filesystems: Dedicated directories with strict permissions."
],
impact: "Ensures data sovereignty and compliance with regulations."
},
{
title: "Compute Isolation",
description: "Providing dedicated compute resources (CPU, memory) to specific workloads or tenants to guarantee performance and prevent 'noisy neighbor' issues.",
examples: [
"Virtual Machines (VMs): Dedicated VMs per tenant or critical application.",
"Containers: CPU limits and requests, memory limits and requests in Kubernetes; CPU pinning.",
"Bare Metal: Dedicated physical servers for high-performance or sensitive workloads."
],
impact: "Guarantees SLA compliance and predictable performance."
},
{
title: "Messaging Isolation",
description: "In distributed systems heavily reliant on messaging, ensuring that message queues or topics used by one service or tenant don't become overwhelmed or compromised by another.",
examples: [
"Message Brokers: Separate queues/topics per service/tenant, dedicated Kafka topics, separate SQS queues, consumer groups for workload distribution.",
"Resource limits: Apply resource limits on message broker instances."
],
impact: "Prevents queue starvation and ensures reliable messaging."
}
],
network: [
{
title: "Network Segmentation",
description: "Dividing the network into distinct logical or physical segments to control traffic flow and limit the blast radius of security breaches.",
examples: [
"Cloud: Virtual Private Clouds (VPCs), Virtual Networks (VNets), subnets, Network Security Groups (NSGs), Security Lists.",
"On-Prem: VLANs, firewalls, ACLs."
],
impact: "Limits blast radius of security incidents."
},
{
title: "Traffic Isolation",
description: "Ensuring that network traffic for one service or tenant is routed independently or given priority, preventing interference or eavesdropping.",
examples: [
"VPNs: Dedicated VPNs for different business units or secure connections.",
"Service Meshes: Network policies, traffic splitting, and routing rules applied at the application level (e.g., Istio, Linkerd).",
"Load Balancers: Dedicated load balancers or specific listener rules for different applications/tenants."
],
impact: "Prevents eavesdropping and ensures traffic prioritization."
},
{
title: "DNS Isolation",
description: "Managing DNS records such that one tenant's domain or service names cannot interfere with or impersonate another's.",
examples: [
"Separate DNS zones for different tenants or environments.",
"Private DNS services (e.g., AWS Route 53 Private Hosted Zones).",
"Strict validation of DNS updates."
],
impact: "Avoids DNS spoofing and ensures correct service resolution."
},
{
title: "Policy Enforcement",
description: "Granular control over network communication between individual workloads (e.g., pods in Kubernetes). Defines which pods can communicate with which other pods or external services.",
examples: [
"Kubernetes Network Policies.",
"Calico network policies.",
"Cilium network policies."
],
impact: "Enables zero-trust networking principles."
