* Understanding Organization Policies:
* Organization policies are rules that can be set at different levels of the resource hierarchy in GCP to enforce governance and compliance.
* These policies can be set at the organization node, folders, and projects, and they are inherited down the hierarchy unless explicitly overridden.
* Hierarchy and Policy Inheritance:
* The provided resource hierarchy has an organization node (Example.com), folders (Folder 1 and Folder 2), and a project (Project 2) under Folder 2 with a specific VPC (VPC A).
* Each node in the hierarchy can have its own policies, and these policies are inherited by child nodes unless overridden.
* Analyzing the Policies in the Hierarchy:
* Organization Node Policy:
json
Copy code
{ "constraint": "constraints/compute.restrictLoadBalancerCreationForTypes", "listPolicy": { "allValues":
"DENY" } }
* This policy at the organization node denies all load balancer types.
* Folder 2 Policy:
json
Copy code
{ "constraint": "constraints/compute.restrictLoadBalancerCreationForTypes", "listPolicy": { "deniedValues":
["INTERNAL_TCP_UDP", "INTERNAL_HTTP_HTTPS"] } }
* This policy at Folder 2 denies the creation of INTERNAL_TCP_UDP and
INTERNAL_HTTP_HTTPS load balancers.
* Project 2 Policy:
json
Copy code
{ "constraint": "constraints/compute.restrictLoadBalancerCreationForTypes", "listPolicy": { "deniedValues":
["EXTERNAL_TCP_PROXY", "EXTERNAL_SSL_PROXY"] } }
* This policy at Project 2 denies the creation of EXTERNAL_TCP_PROXY and EXTERNAL_SSL_PROXY load balancers.
* Policy Application to VPC A:
* Since policies are inherited, VPC A (which is within Project 2 under Folder 2) will be affected by the policies of both Folder 2 and Project 2.
* Combining the denied values from both Folder 2 and Project 2:
* From Folder 2: INTERNAL_TCP_UDP, INTERNAL_HTTP_HTTPS
* From Project 2: EXTERNAL_TCP_PROXY, EXTERNAL_SSL_PROXY
* Conclusion:
* VPC A will have the following load balancer types denied: INTERNAL_TCP_UDP, INTERNAL_HTTP_HTTPS, EXTERNAL_TCP_PROXY, EXTERNAL_SSL_PROXY.
