About Gateway Manager
The Gateway Manager is a Kong Konnect functionality module that lets you catalog, connect to, and monitor the status of all control planes (CP) and data plane nodes (DPs) in one place, as well as manage control plane configuration.
The Gateway Manager overview page displays a list of control planes currently owned by the organization. From here, you can add or delete control planes, or go into each individual control plane to manage data plane nodes and their global configuration.
Figure 1: Example Gateway Manager dashboard with several control planes, including the default control plane, a KIC control plane, and control planes for development and production.
With Konnect hosting the control plane, a data plane node doesn’t need a database to store configuration data. Instead, configuration is stored in-memory on each node, and you can easily update all data plane nodes in a control plane with a few clicks. This model applies whether the nodes are managed on-premise, in cloud-hosted environments, or through our fully managed SaaS offering with Dedicated Cloud Gateways or Serverless Gateways.
The Gateway Manager, and the Kong Konnect application as a whole, does not have access or visibility into the data flowing through your data plane nodes, and it does not store any data except the state and connection details for each node.
Control planes
Konnect manages data plane configuration via control planes.
Control planes come in three types:
-
Kong Gateway control plane: A collection of Kong Gateway data plane nodes sharing the same configuration and behavior space. Each control plane manages configurations independently.
-
Control plane group: A type of control plane that manages central data plane nodes for multiple control planes. It collects configuration from its member control planes and applies the aggregate config to a group of nodes.
This means that teams within a group share a cluster of Kong Gateway data plane nodes, where each team has its own segregated configuration.
-
Kong Ingress Controller Monitor the configuration of Kubernetes-based Kong Gateway data plane nodes.
You can find a list of all control planes in your organization on the Gateway Manager overview.
Access to each control plane is configurable on a team-by-team basis using entity-specific permissions. For more information, see Administer teams.
Kong Gateway control planes
Every region in every organization starts with one default control plane. With Konnect you can configure additional Kong Gateway control planes, each of which will have isolated configuration. Use multiple control planes in one Konnect organization to manage data plane nodes and their configuration in any groupings you want.
Some common use cases for using multiple control planes include:
- Environment separation: Split environments based on their purpose, such as development, staging, and production.
- Region separation: Assign each control plane to a region or group of regions. Spin up data plane nodes in those regions for each control plane.
- Team separation: Dedicate each control plane to a different team and share resources based on team purpose.
- Resource hosting and management separation: Run a hybrid control plane with self-hosted data plane nodes, and a separate Dedicated Cloud Gateway control plane with Kong-managed nodes.

Figure 2: Example control plane group configuration for two control planes: a hybrid control plane and a fully-managed Dedicated Cloud Gateway control plane.
The hybrid control plane consists of a Kong-managed CP and self-managed DP nodes, while the Dedicated Cloud Gateway control plane consists of fully-managed CP and DP nodes. Konnect is the SaaS-managed global management plane that manages all of the control planes, while the control planes manage configuration for data plane nodes.
Control plane configuration
For each control plane, you can spin up data plane nodes and configure the following Kong Gateway entities:
- Gateway services
- Routes
- Consumers
- Consumer Groups
- Plugins
- Upstreams
- Certificates
- SNIs
- Vaults
- Keys
When there are multiple control planes, any entity configuration only applies to the control plane that it was created in. Consumers and their authentication mechanisms don’t carry over to other control planes.

Control plane groups
A control plane group is a read-only control plane that combines configuration from its members, which are standard Kong Gateway control planes. All of the members of a control plane group share the same cluster of data plane nodes.
The benefits of a control plane group include:
- Shared infrastructure, individual config: Users or organizations can share infrastructure, while teams still have their own standard control planes to manage individual configuration.
- Modular clusters: Combine standard control planes in different ways to create unique configurations for different purposes.
- Workspaces in the cloud: Control plane groups function similarly to Kong Gateway workspaces, with the added benefit of a cloud control plane.

Control plane dashboard
For each control plane, you can view traffic, error rate, and Kong Gateway service analytics for its data plane nodes. This allows you to see how much of a control plane is used. You can also select the time frame of analytics that you want to display.
Deleting a control plane
Warning: Deleting a control plane is irreversible. Make sure that you are certain that you want to delete the control plane, and that all entities and data plane nodes in the control plane the have been accounted for.
To delete a control plane, you can use the Gateway Manager or the Konnect Control Plane API.
When a control plane is deleted, all associated entities are also deleted. This includes all entities configured in the Gateway Manager for this control plane. As a best practice, back up a control plane’s configuration before deleting it to avoid losing necessary configuration.
Data plane nodes that are still active when the control plane is deleted will not be terminated, but they will be orphaned. They will continue processing traffic using the last configuration they received until they are either connected to a new control plane or manually shut down.
Data plane nodes
A data plane node is a single Kong Gateway instance. Data plane nodes service traffic for the control plane.
You can deploy your data plane nodes in the following ways:
-
Fully-managed:
-
Dedicated Cloud Gateways data plane nodes are completely managed by Kong in the cloud provider of your choice. You maintain control over the size and location of the gateway infrastructure, while Kong oversees the management of each instance and the entire cluster for you. You can use the Dedicated Cloud Gateways wizard in Gateway Manager to provision a Kong Gateway data plane node in a cloud provider.
-
Serverless Gateways data plane nodes are also completely managed by Kong but all the infrastructure options are abstracted from the user. It is not possible to configure the placement, size, or number of data plane nodes.
-
- Self-managed: The data plane nodes are hosted either on your own systems or in an external cloud provider. You can use the script in Gateway Manager to provision a Kong Gateway data plane node in a Docker container running Linux, on MacOS, or on Windows.
The following table can help you decide which data plane node strategy to use based on your use case:
Use case | Data plane node strategy | Solution |
---|---|---|
Reducing latency is important to your organization. | Dedicated Cloud Gateways | Supports multiple regions on AWS and Azure: - AWS regions: Sydney, Tokyo, Singapore, Frankfurt, Ireland, London, Ohio, Oregon. - Azure regions: Frankfurt, Ireland, UK South, Virginia, Washington |
Your organization operates in an industry with strict data protection and privacy requirements. | Dedicated Cloud Gateways | Using the private gateway option, Kong provisions a private network load balancer and only exposes the IP address in the UI. |
Your organization needs high availability with zero downtime when upgrading data plane nodes. | Dedicated Cloud Gateways | There’s no downtime when upgrading your data plane nodes. Additionally, you can pre-warm your cluster by specifying the number of requests per second so that the first requests don’t have to wait for the infrastructure to scale up. |
You have infrastructure in multiple clouds. | Dedicated Cloud Gateways | Dedicated Cloud Gateways allows you to run a multi-cloud solution that allows you to standardize API operations across the board to reduce complexity and increase agility. |
You need very rapid provisioning for experimentation and sandbox use cases. | Serverless Gateways | Serverless Gateways offer sub-minute provisioning times and enable rapid iteration and development lifecycles. |
You use a cloud provider (other than AWS or Azure) for hosting, or don’t want to host in the cloud because of organizational policy. | Self-managed | You can self-manage your data plane nodes in AWS, Azure, and Google Cloud. Or, you can deploy self-managed data plane nodes in macOS, Windows, Linux (Docker), or Kubernetes. |
See the data plane node installation options for more information.
Plugins
You can extend Konnect by using plugins. Kong provides a set of standard Lua plugins that get bundled with Konnect. The set of plugins you have access to depends on your installation.
Custom plugins can also be developed by the Kong Community and are supported and maintained by the plugin creators. If they are published on the Kong Plugin Hub, they are called Community or Third-Party plugins.
See the Konnect plugin ordering documentation for more information.
