As complexity and dynamism increase, the one thing that stays the same is the network!
“While I genuinely believe that the network will play an immensely strategic role in the microservices world, inspecting and storing billions of API calls on a daily basis will require significant computing and storage resources. In addition, deep packet inspection could be challenging at line rates; so, sampling, at the expense of full visibility, might be an alternative.”
These challenges are addressed with stream processing. This approach applies processing to the data before anything is written to disk, which is a scalable approach to L2-L7 traffic analysis. For this reason, the ExtraHop platform can analyze up to a sustained line rate of 40 Gbps (even with SSL decryption).
