This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

Trial ? Worth pursuing. It is important to understand how to build up this capability. Enterprises should try this technology on a project that can handle the risk.

For several years now, the Linux kernel has included the extended Berkeley Packet Filter (eBPF) virtual machine and provided the ability to attach eBPF filters to particular sockets. But extended BPF goes far beyond packet filtering and allows custom scripts to be triggered at various points within the kernel with very little overhead. Although this technology isn't new, it's now coming into its own with the increasing use of microservices deployed as orchestrated containers. Service-to-service communications can be complex in these systems, making it difficult to correlate latency or performance issues back to an API call. We're now seeing tools released with prewritten eBPF scripts for collecting and visualizing packet traffic or reporting on CPU utilization. With the rise of Kubernetes, we’re seeing a new generation of security enforcement and instrumentation based on eBPF scripts that help tame the complexity of a large microservices deployment.
