#### Cloud Provider Enhancement

* AWS:

  * New 'service.beta.kubernetes.io/aws-load-balancer-extra-security-groups' Service annotation to specify extra Security Groups to be added to ELB created by AWS cloudprovider ([#45268](https://github.com/kubernetes/kubernetes/pull/45268), [@redbaron](https://github.com/redbaron))

In addition, support for NVMe disks has been added to Kubernetes, and a service of type LoadBalancer can now be backed with an NLB instead of an ELB (alpha).

### Azure

SIG Azure worked on improvements in the cloud provider, including significant work on the Azure Load Balancer implementation.

### Cluster Lifecycle

* AWS: Avoid spurious ELB listener recreation - ignore case when matching protocol ([#47391](https://github.com/kubernetes/kubernetes/pull/47391), [@justinsb](https://github.com/justinsb))

- Prevented AWS Network Load Balancer security groups ingress rules to be deleted by ensuring target groups are tagged. ([#73594](https://github.com/kubernetes/kubernetes/pull/73594), [@masterzen](https://github.com/masterzen))
- AWS ELB health checks will now use HTTPS/SSL protocol for HTTPS/SSL backends. ([#70309](https://github.com/kubernetes/kubernetes/pull/70309), [@2rs2ts](https://github.com/2rs2ts))

rather than failing silently. ([#60125](https://github.com/kubernetes/kubernetes/pull/60125), [@vainu-arto](https://github.com/vainu-arto))

* AWS Security Groups created for ELBs will now be tagged with the same additional tags as the ELB; that is, the tags specified by the "service.beta.kubernetes.io/aws-load-balancer-additional-resource-tags" annotation. This is useful for identifying orphaned resources. ([#58767](https://github.com/kubernetes/kubernetes/pull/58767), [@2rs2ts](htt...

- Added `service.beta.kubernetes.io/aws-load-balancer-security-groups` annotation to set the security groups to the AWS ELB to be the only ones specified in the annotation in case this is present (does not add `0.0.0.0/0`).  ([#62774](https://github.com/kubernetes/kubernetes/pull/62774), [@Raffo](https://github.com/Raffo))

### SIG Azure

* Adds EndpointSlice integration to kube-proxy, can be enabled with EndpointSlice feature gate. ([#81430](https://github.com/kubernetes/kubernetes/pull/81430), [@robscott](https://github.com/robscott))
* Azure supports IPv6 only on ELB not ILB. The cloud provider will return an error if the service is internal and is IPv6. ([#80485](https://github.com/kubernetes/kubernetes/pull/80485), [@khenidak](https://github.com/khenidak))
