h2(#identity). Identity provider
* LDAP login to authenticate users by username/password using the LDAP protocol, supported by many services such as OpenLDAP and Active Directory.
* PAM login to authenticate users by username/password according to the PAM configuration on the controller node.
+h2(#postgresql). PostgreSQL
+
+Arvados works well with a standalone PostgreSQL installation. When deploying on AWS, Aurora RDS also works but Aurora Serverless is not recommended.
+
h2(#storage). Storage backend
Choose which backend you will use for storing and retrieving content-addressed Keep blocks.
Choose which backend you will use to schedule computation.
* On AWS EC2 and Azure, you probably want to use @arvados-dispatch-cloud@ to manage the full lifecycle of cloud compute nodes: starting up nodes sized to the container request, executing containers on those nodes, and shutting nodes down when no longer needed.
-* For on-premise HPC clusters using "slurm":https://slurm.schedmd.com/ use @crunch-dispatch-slurm@ to execute containers with slurm job submissions.
+* For on-premises HPC clusters using "slurm":https://slurm.schedmd.com/ use @crunch-dispatch-slurm@ to execute containers with slurm job submissions.

* For single node demos, use @crunch-dispatch-local@ to execute containers directly.

For a small demo installation, it is possible to run all the Arvados services on a single node. Special considerations for single-node installs will be noted in boxes like this.
h2(#dnstls). DNS entries and TLS certificates
-The following services are normally public-facing and require DNS entries and corresponding TLS certificates. Get certificates from your preferred TLS certificate provider. We recommend using "Let's Encrypt":https://letsencrypt.org/. You can run several services on same node, but each distinct hostname requires its own TLS certificate.

+Setting up Arvados is easiest when Wildcard TLS and wildcard DNS are available. It is also possible to set up Arvados without wildcard TLS and DNS, but not having a wildcard for @keep-web@ (i.e. not having *.collections.@ClusterID.example.com@) comes with a tradeoff: it will disable some features that allow users to view Arvados-hosted data in their browsers. More information on this tradeoff caused by the CORS rules applied by modern browsers is available in the "keep-web URL pattern guide":../api/keep-web-urls.html.
