Modify the subnets as specified in VPC requirements. To make it easier to find related objects, in the Filter by VPC field, select your new VPC.Ĭlick Subnets and what AWS calls the private subnets labelled 1 and 2, which are the ones you will use to configure your main workspace subnets. When viewing your new VPC, click on the left navigation items to update related settings on the VPC. To resize them, for example to share one VPC with multiple workspaces that all need separate subnets, click Customize subnet CIDR blocks.Įnsure the following fields at the bottom are enabled: Enable DNS hostnames and Enable DNS resolution. Your Databricks workspace needs at least two private subnets. Those subnets aren’t used directly by your Databricks workspace, but they are required to enable NATs in this editor.įor private subnets, click 2 for the minimum for workspace subnets. Databricks recommends including the region in the name.įor VPC address range, optionally change it if desired.įor public subnets, click 2. In the Name tag auto-generation type a name for your workspace. Ingress (inbound): Required for all workspaces (these can be separate rules or combined into one):Īllow TCP on all ports when traffic source uses the same security groupĪllow UDP on all ports when traffic source uses the same security group Ensure these ports are open by January 31, 2024. Only required if you enable the compliance security profile.Ĩ443 through 8451: Future extendability. This is only required if you use PrivateLink.Ģ443: Supports FIPS encryption. Security groups must have the following rules:Īllow all TCP and UDP access to the workspace security group (for internal traffic)Īllow TCP access to 0.0.0.0/0 for these ports:Ĥ43: for Databricks infrastructure, cloud data sources, and library repositoriesĦ666: for secure cluster connectivity. You can reuse existing security groups rather than create new ones. For workspaces that are configured to use a customer-managed VPC, you can use an egress firewall or proxy appliance to limit outbound traffic to a list of allowed internal or external data sources.ĭatabricks must have access to at least one AWS security group and no more than five security groups. Limit outgoing connections: By default, the data plane does not limit outgoing connections from Databricks Runtime workers. And there is no need for the complex VPC peering configurations that might be necessary with other solutions.Ĭonsolidation of VPCs: Multiple Databricks workspaces can share a single data plane VPC, which is often preferred for billing and instance management. Optionally configure smaller subnets for a workspace, compared to the default CIDR /16. Simplified network operations: Better network space utilization. This limited set of permissions can make it easier to get approval to use Databricks in your platform stack. For example, there is no need for permission to create VPCs. And you don’t need to grant Databricks as many permissions via cross-account IAM role as you do for a Databricks-managed VPC. Lower privilege level: You maintain more control of your own AWS account. Security policies that prevent PaaS providers from creating VPCs in your own AWS account.Īn approval process to create a new VPC, in which the VPC is configured and secured in a well-documented way by internal information security or cloud engineering teams. To configure your workspace to use AWS PrivateLink for any type of connection, it is required that your workspace use a customer-managed VPC.Ī customer-managed VPC is good solution if you have:
