- Scaling Kubernetes
- There are monitoring and logging systems, but its tough to monitor everything accurately in a distributed environment
- The Kubernetes cluster does not expose kernel level monitoring data
- Process/Service Specific Monitoring
- Since Kubernetes Service is essentially a process run by the linux Kernel
- With eBPF it is easy to monitor a specific process, so teams can monitor a process running across all of their infrastructure nodes.
- More granular than logs
- No special instrumentation needed
- unlike the sidecar pattern eBPF install a very small overhead
- Challenges
- There is no easy way to install eBPF on all nodes of the cluster, orchestration is a challenge, they can use Cilium like tools to get more visibility into their cluster though.

While mathematics is in itself quite interesting and forms the basis of any modern day research, be it computational biology, machine learning or building complex structure, it can be quite a challenge to decide where to start. That is why i decided to explore Fractals, thinking of it as a bridge between the nature and science. It brings in some really fascinating concepts which should be good enough for me as a gateway go deeper. Fractals are in simple language never ending patterns which keep on repeating without an end, because fractals are never ending they have an infinite perimeter but finite area. Since the patterns repeats indefinitely but if you draw a circle around the peremeter the area will remain finite. It is like adding 1+0.1+0.01+0.001 and never making 2 This video explains the basic concept really well Fractals are found everywhere nature in Trees, Rivers, Branching patterns, Hurricanes and Galaxies. It tries to bring order and understandin...
eBPF provides a powerful way to observe Kubernetes workloads at the Linux kernel level, offering more granular visibility into processes and services than traditional logs. It can help teams monitor specific processes across infrastructure nodes without requiring special application instrumentation, while introducing relatively low overhead compared with approaches such as sidecar-based monitoring.
