Deploy an ExtraHop sensor in AWS
The following procedure guides you through the deployment process of the sensor AMI to monitor your Amazon Web Services (AWS) environment.
After you deploy the sensor in AWS, configure AWS traffic mirroring or remote packet capture (RPCAP) to forward traffic from remote devices to your virtual sensor. AWS traffic mirroring is configurable for all instance sizes and is the preferred method of sending AWS traffic to the EDA 6100v and 8200v sensors.
Important: | If your deployment includes a console, the following workflow ensures the best performance for initial device synchronization. First, connect all sensors to the console, then configure network traffic forwarding to the sensors. |
System requirements
Your environment must meet the following requirements to deploy a virtual ExtraHop sensor in AWS:
- An AWS account
- Access to the Amazon Machine Image (AMI) of the ExtraHop sensor
- The sensor product key
- An AWS instance type that most closely matches the virtual ExtraHop sensor size, as
follows:
Sensors Recommended Instance Type EDA 1000v m5.large (2 vCPU and 8 GB RAM) Reveal(x) EDA 1100v c5.xlarge (4 vCPU and 8 GB RAM) EDA 2000v c5.2xlarge (8 vCPU and 16 GB RAM) EDA 6100v m5.4xlarge (16 vCPU and 64 GB RAM) c5.9xlarge (36 vCPU and 72 GB RAM)*
Reveal(x) EDA 8200v c5n.9xlarge (36 vCPU and 96 GB RAM) Note: Whenever possible, locate the sensor within the same cluster placement group as the devices that are forwarding traffic. This best practice optimizes the quality of feed that the sensor receives. *Recommended when the EDA 6100v cannot be deployed in the same cluster placement group as the monitored traffic. The c5.9xlarge instance has a higher cost, but is more resilient in environments where data feed fidelity is critical.
Important: AWS enforces a session limit of 10 sessions for VPC traffic mirroring; however, the session limit can be increased for sensors running on a c5 dedicated host. We recommend the c5 dedicated host for EDA 8200v and EDA 6100v instances that require a larger session limit. Contact AWS support to request the session limit increase. - (Optional) A storage disk for deployments that include precision packet capture. Refer to
your vendor documentation to add a disk.
- For the EDA 1000v, 1100v, and 2000v add a disk with up to 250 GB capacity.
- For the EDA 6100v and 8200v, add a disk with up to 500 GB capacity.
Create the ExtraHop instance in AWS
Before you begin
The Amazon Machine Images (AMIs) of ExtraHop sensor are not publicly shared. Before you can start the deployment procedure, you must send your AWS account ID to support@extrahop.com. Your account ID will be linked to the ExtraHop AMIs.Next steps
- (Recommended) Configure AWS traffic mirroring to copy network
traffic from your EC2 instances to a high-performance ERSPAN/VXLAN interface on
your sensor.
Tip: If your deployment requires more than 15 Gbps of throughput, divide your traffic mirroring sources across two high-performance ERSPAN/VXLAN interfaces on the EDA 8200v. - Review the Sensor and console post-deployment checklist.
