| ## Node auto provisioning vs. cluster autoscaler | ||
|
|
||
| Cluster autoscaler, the standard Kubernetes autoscaler solution, requires the use of same VM size node pools, and scales pre-existing node pools up or down. NAP works instead at the cluster level, and manages single-instance VMs, also handling the provisioning experience for multiple VM sizes and architecture at once. NAP allows for better bin-packing, cost savings, and performance than cluster autoscaler. |

CAS also works t cluster level but we can disable or enable multiple nodepools at a time. can we rephrase it? (because it might confuse some customers)
|
|
||
| NAP works at the infrastructure level, and adjusts the quantity and sizes of VMs. NAP can be paired with application-level scalers, which affect CPU/Memory resource allocation and pod replica count, such as [KEDA](https://learn.microsoft.com/azure/aks/keda-about), [Horizontal Pod Autoscaler](https://learn.microsoft.com/azure/aks/concepts-scale#horizontal-pod-autoscaler), or [Vertical Pod Autoscaler](https://learn.microsoft.com/en-us/azure/aks/vertical-pod-autoscaler).

May be a couple of examples (i.e scenario based - since it is a blog post) ?

PTAL lets add more color, behind the scenes stuff for the power user even for Introductory blog.

Perhaps worth deep diving into a section on 1 or 2 key important bits from the new announcement in your blog for example: Improved ugprade experience and Observability could be a deep dive topic ?

As a customer when should i be using CAS and when should i be using NAP . Can you give me some real world examples with suggestions.

Again could you be more specific on an opinion for us to have on why you should go with Karpenter and when / where NAP is better?

What are the challenges with OSS version.
| Karpenter is the OSS project that schedules workloads for efficient compute usage. Our [AKS Karpenter Provider (self-hosted)](https://github.com/Azure/karpenter-provider-azure) makes use of Karpenter on Azure available. Node Auto-provisioning (NAP) is our managed add-on for Karpenter on AKS that manages certain aspects of the Karpenter experience on Azure. NAP is the recommended mode for most users for a few reasons. | ||

Can you give some description on how each of these are managed and potential deep dive into more salient / frequently asked one.
|
|
||
| To get started with NAP, you can visit the [Node Auto Provisioning documentation](https://learn.microsoft.com/azure/aks/node-autoprovision). The documentation includes resources, requirements, and all the info needed to enable node auto provisioning in your cluster today. | ||

| ## Roadmap + Next Steps |

Like Sean suggested - Blogs are a funnel into how AKS PG are thinking , you can tell the audience why we are prioritizing something first vs the other be more descriptive and provide behind the scenes view - think of power user in mind as they are the audience here.
| ## Roadmap + Next Steps | ||
|
|
||
| We’re continuing to expand the capabilities for NAP for additional feature support and performance. Our upcoming roadmap of feature support includes: | ||

Provide a little bit more color what are doing first , milestones tentatively , GH roadmap links to these ?

||
| ## Get Involved | ||
|
|
||
| Contribute to the open-source [Azure Karpenter Provider](https://github.com/Azure/karpenter-provider-azure), which Node Auto Provisioning is based on. The provider features over 37 releases, 1000+ PRs, 14,000 CI runs, and a growing communitiy of contributors. |

Provide a link to our AKS me series here and your YT video too . This is a good place for external segway .

Start / lead with the problem statement for Why NAP came into being - what was the status before this . Who were the customers / personas requesting for this and why .
| - Better performance, reliability, error handling (including handling of provisioning failures), and security. Numerous bugfixes and issues resolved. | ||
| - [Extensive test coverage](https://github.com/Azure/karpenter-provider-azure/tree/main/test). Eight new E2E test suites, ~100 total scenarios. 95% unit test coverage. | ||
| - Github Contributions welcome! (GitHub Codespace-based dev/test environment in 5 min) | ||

| - Windows support | ||
| - Private Cluster Support | ||
| - and more... |
