Abstract

Claims (69)

1. A method, comprising:

receiving, by a firewall management service, a security policy definition allowing a first set of cloud resource instances labeled by a first tag to service requests initiated by a second set of cloud resource instances labeled by a second tag, wherein the first set of cloud resource instances and the second set of cloud resource instances are interconnected by a private network;

generating a first security group comprising an inbound firewall rule for the first set of cloud resource instances, wherein the inbound firewall rule comprises a source communication endpoint identifier, a transport layer protocol identifier, and a port identifier;

generating a second security group comprising an outbound firewall rule for the second set of cloud resource instances, wherein the outbound firewall rule comprises a destination communication endpoint identifier, the transport layer protocol identifier, and the port identifier;

substituting, in the inbound firewall rule associated with the first security group, the source communication endpoint identifier with an identifier of the second security group;

substituting, in the outbound firewall rule associated with the second security group, the destination communication endpoint identifier with an identifier of the first security group;

associating, with the first security group, a first cloud resource instance labeled by the first tag;

associating, with the second security group, a second cloud resource instance labeled by the second tag;

labeling the first security group and the second security group with a service-reserved tag preventing association of the first security group and the second security group with other cloud resource instances; and

causing a firewall service to partition the private network into a first logical network and a second logical network by implementing the first security group and the second security group, wherein the first logical network interconnects the first set of cloud resource instances, and wherein the second logical network interconnects the second set of cloud resource instances.

2. The method of claim 1 , wherein the first tag indicates at least one of: a cloud resource function, a cloud resource type, or an application type.

3. The method of claim 1 , further comprising:

receiving, from a cloud management service, a notification of deletion of the first cloud resource instance;

determining that no active cloud resource instances remain associated with the first security group; and

deleting the first security group.

4. The method of claim 1 , wherein the first cloud resource instance runs within a first virtual private cloud and the second cloud resource instance runs within a second virtual private cloud, the method further comprising:

receiving, from a cloud management service, a notification of deletion of a peering link between the first virtual private cloud and the second virtual private cloud;

deleting the first security group; and

deleting the second security group.

5. The method of claim 1 , wherein associating the first cloud resource instance with the first security group is performed responsive to receiving, from a cloud management service, a notification of activation of the first cloud resource instance labeled by the first tag.

6. A computer system, comprising:

a memory; and

a processing device operatively coupled to the memory, the processing device to:

identify a first set of cloud resource instances labeled by a first tag and a second set of cloud resource instances labeled by a second tag, wherein the first set of cloud resource instances and the second set of cloud resource instances are interconnected by a private network;

generate a first security group comprising an inbound firewall rule associated with the first set of cloud resource instances, wherein the inbound firewall rule specifies a source communication endpoint identifier, a transport layer protocol identifier, and a port identifier;

generate a second security group comprising an outbound firewall rule associated with the second set of cloud resources instances, wherein the outbound firewall rule specifies a destination communication endpoint identifier, the transport layer protocol identifier, and the port identifier;

substitute, in the inbound firewall rule associated with the first security group, the source communication endpoint identifier with an identifier of the second security group;

substitute, in the outbound firewall rule associated with the second security group, the destination communication endpoint identifier with an identifier of the first security group;

label the first security group and the second security group with a service-reserved tag preventing association of the first security group and the second security group with other cloud resource instances; and

partition, by invoking the first security group and the second security group, the private network into a first logical network interconnecting the first set of cloud resource instances and a second logical network interconnecting the second set of cloud resource instances.

7. The computer system of claim 6 , wherein invoking the first security group further comprises:

applying the first security group based on a security policy definition allowing cloud resource instances labeled by the first tag to communicate to cloud resource instances labeled by the second tag.

8. The computer system of claim 6 , wherein the first tag indicates at least one of: a cloud resource function, a cloud resource type, or an application type.

9. The computer system of claim 6 , wherein the processing device is further configured to:

receive, from a cloud management service, a notification of activation of a first cloud resource instance labeled by the first tag; and

associate the first cloud resource instance with the first security group.

10. The computer system of claim 6 , wherein the processing device is further configured to:

receive, from a cloud management service, a notification of deletion of a cloud resource instance associated with the first security group;

determine that no active cloud resource instances remain associated with the first security group; and

delete the first security group.

11. The computer system of claim 6 , wherein a first cloud resource instance runs within a first virtual private cloud and a second cloud resource instance runs within a second virtual private cloud, and wherein the processing device is further to:
