Instance Type: i3en.large (or, t3.micro if you want to test and are willing to accept packet loss and memory constraints).

Launch EC2 InstancesĪssuming that you already have sufficient knowledge about launching EC2 instances, create a new instance with the following profile: In this example, we will use simple T3.micro AMI Linux instances to create traffic to be captured. One thing to keep in mind: This will not be compatible with any "Free Tier" service levelsĪdditionally, one or more traffic generators will also need to be set up. Likewise, only the newer "Nitro" instance types can support traffic mirroring, so if monitroing an existing instance is desired, the instance will need to be upgraded if it isn't on a newer instance type.

Support for this exists in the latest AMI Linux and FreeBSD images, but not in older ones. This feature will require the use of the newer Elastic Network Adapter. That said, capture with a T3 instance is not recommended for production, if a lot of bandwidth is being monitored. Therefore, for experimentation, a T3 instance will allow for use of the feature, with significantly lower cost. The cost involved with the smallest version of this instance type can still be over $100 per month. Large high-speed local ephemral hardware storage that provides high-speed, multi-terabyte landing zone for pcap archives.Enhanced networking offers an adapter that can scale from 25Gbps to 100GBps.

For this, a storage-optimized EC2 instance, the I3en, will be suitable for two reasons: As a start, we will try to build a system that will capture traffic from one or more traffic sources. The following blog post introduces us to traffic mirroring with an example of setting it up in the AWS console:įirst thing, it is important to identify an instance that will be best suited for the job. It is a really interesting feature, and as such I've wanted to try it out, as network traffic inspection and collection is notoriously challenging in the AWS cloud environment. This feature is available on any compute workload that is built using the new AWS Nitro System (link contains supported EC2 instance types).

Earlier this year, AWS made available a new feature named " Traffic Mirroring" to their customers.
