AKS hybrid offline download preview experience to install and update

Offline Download Preview

For everyone in the tech industry, chances are we can all unite against a common enemy… poor internet connection. How many times in a work day do you hear or say the phrase “…can you hear me now…” on a video call? Unfortunately, this feature won’t help you there, but it can help you in your hybrid AKS deployments. In the AKS hybrid launch in Septemberwe are pleased to announce a offline download preview!

Offline download allows you to install and update your AKS hybrid clusters in a disconnected environment. Unreliable or intermittent connectivity is one of the most common reasons behind the need to run AKS workloads on premises. However, the hybrid AKS deployment requires good connectivity and sufficient bandwidth to pull the hybrid AKS images from SFS. With offline download, we’re changing that. Another reason to run workloads on premises is security and compliance. Offline download provides an additional layer of security by allowing you to pre-download images. Once you get the images to your local share, you can run a security scan on the images before you deploy them to your production environment. These types of scenarios influenced us to bring an offline download feature to the AKS hybrid experience. Introducing 2 capabilities in offline download: in the place Y off site.

Offline download on the site

A offline download on site This is when you download the AKS hybrid images directly to a local share on your deployment site, and then install or update with the previously downloaded images on the local share. Downloading on the site bypasses the default installation and upgrade steps. Between downloading the images and installing locally or upgrading with those images, you can run a security scan or whatever you need to do before deployment. The following diagram shows a visual flow of an offline download on the site.

Offline download off site

A offline download off site is when you download the images to a local share at an external location (a location that is different from your deployment site), use a tool of your choice to transfer the images to a local share at the deployment site, and then install or update locally with those images This scenario is suitable for customers struggling with low bandwidth or unreliable connectivity by allowing you to deploy offline. The following diagram shows a visual flow of an offline off-site download.
