-
-Landscape 23.03 manages all versions of Ubuntu 16.04 LTS (Xenial Xerus) onwards. Landscape 23.03 also manages two future Ubuntu releases, which includes the following interim release (Ubuntu 23.10) and LTS release (Ubuntu 24.04).
+| Method | Use case |
+|--------|----------|
+| {ref}`Quickstart <how-to-quickstart-installation>` | Single-machine deployment, evaluation, or smaller environments. Not recommended for production at scale. |
+| {ref}`Juju <how-to-juju-installation>` | Scalable, production-grade deployment with high availability. |
+| {ref}`Manual <how-to-manual-installation>` | Scalable deployment without Juju. Suitable when a Juju environment is not available. |
 
-Landscape 24.04 LTS manages the previous four Ubuntu LTS releases, from Ubuntu 16.04 LTS (Xenial Xerus) onwards. Landscape 24.04 LTS will also manage future Ubuntu releases, including Ubuntu 26.04 LTS, and interim releases Ubuntu 24.10, Ubuntu 25.04, and Ubuntu 25.10.
+## Supported versions and release cycles
 
-Compatibility beyond this range to older and newer versions of Ubuntu is on a best effort basis and is not guaranteed.

 ```
 
-## Landscape PPAs
-
-You can access self-hosted Landscape from one of our PPAs:
-
-- **Long Term Support (LTS)**: Our LTS PPA that comes with 10 years of support and aligns with the Ubuntu LTS release cadence. This is our most stable PPA and includes five point release updates after the initial release. These updates include bug fixes and security patches. We recommend using LTS versions for production deployments. New LTS releases are released every two years, usually in April of each even year, and the point releases are typically published in August and February of each year.
-- **Latest Stable**: A stable rolling release for users who need access to the latest features. The latest stable PPA is suitable for production, but each version is only supported until the next latest stable release. Users on this PPA should always upgrade to the most recent release for continuous support. New latest stable versions are released every six months, usually around October and April.
-- **Beta**: The newest beta features, mainly used for testing and development. You can explore the latest features here, but stability is not guaranteed. The beta PPA should not be used for production deployments.
-
-## Installation
-
-Self-hosted Landscape consists of two parts:
+LTS versions are released every two years and are recommended for production deployments. Latest stable versions are released every six months; each is supported only until the next release.
 
-- **Database server**
-- **Application server**
+The Landscape Server charm follows similar release cycles to the other installation methods, although the timing can vary slightly. For more details and the charm-specific Ubuntu compatibility, see the [Landscape Server charm page on Charmhub](https://charmhub.io/landscape-server).
 
-Depending on your deployment method, these may exist on the same machine or different machines. Here is how you can get started:
+For more information, see {ref}`reference-supported-versions-and-ppas`.
 
-### Quickstart
+## Package sources (PPAs)
 
-- **{ref}`Quickstart installation <how-to-quickstart-installation>`**, for when you don't have Juju but quickly want to check out self-hosted Landscape. Not recommended for production environments when having more than 500 clients.
+Self-hosted Landscape is distributed via the following PPAs:
 
-### Juju deployed
-
-- **{ref}`Juju installation <how-to-juju-installation>`** for a truly scalable deployment.
-
-### Manual installation
+```{include} ../../reference/_includes/landscape-ppas-table.md
+```
 
-- **{ref}`Manual installation <how-to-manual-installation>`**: for when you don't have a suitable Juju environment but need a scalable deployment.
+## Ubuntu compatibility
 
-## Installation requirements
+Each Landscape Server release manages a specific range of Ubuntu versions, including selected older LTS releases and upcoming LTS and interim releases. Compatibility outside the documented range is on a best-effort basis and not guaranteed.
 
-### System Requirements
+For the version-by-version compatibility mapping, see {ref}`reference-supported-versions-and-ppas`.
 
-The bare minimum compute power required to run Landscape is 4 GB of RAM and 20 GB of disk space.
+Note that Landscape Client is available in the `main` repository for all Ubuntu releases and is published independently of Landscape Server. For information on installing Landscape Client, see {ref}`how-to-install-landscape-client`.
 
-- The `landscape-server-quickstart` package requires 2 vCPUs or one dual core processor
-- The Juju-based installation can be deployed on a single vCPU, but a minimum of 2 is recommended.
+## System requirements
 
-Our recommendation is to allocate 8 vCPUs or cores, 16GB RAM, and 512 GB of storage. When performing a manual or Juju based installation to address high availability requirements, each machine including the Juju controller should be allocated this many resources for the best outcome. If Landscape will be responsible for repository mirroring, it is advisable to mount an additional 2 TB of storage to the machine running the Landscape Server software.
+Landscape Server runs on Ubuntu Server (amd64, arm64, s390x, or ppc64el). Supported Ubuntu versions are listed in {ref}`reference-supported-versions-and-ppas`.
 
-One machine with these specifications will run the landscape-server-quickstart package. When using Juju or manually installing across multiple machines, none of the machines should be configured below these baseline compute power specifications.
+```{include} ../../reference/_includes/landscape-sizing-table.md
+```
 
-The operating system to run Landscape Server and its dependencies are Ubuntu Server 22.04 LTS or 24.04 LTS on amd64, arm64, s390x, or ppc64el CPU architectures.
+In high-availability or other multi-node deployments (Juju or manual), apply the recommended allocation to each machine, including the Juju controller.
 
 (explanation-network-access)=
-### Network access
+## Network access
 
 Any client machines you manage with Landscape should be able to access your Landscape Server installation over network ports 80/TCP (HTTP) and 443/TCP (HTTPS). You can optionally open port 22/TCP (SSH) as well for maintenance of your Landscape Server.
 
@@ -97,17 +78,3 @@ Your Landscape Server will also need the following external network access:
 - HTTPS access to `api.snapcraft.io`, `dashboard.snapcraft.io`, `login.ubuntu.com`, and `*.snapcraftcontent.com` if using or downloading snaps (e.g., `landscape-api`)
 
 If this external network access is unavailable, Canonical's professional services include assistance with setting up Landscape in a fully airgapped environment.
