Linkerd
* rust based data plane is pretty light
* We can use any Ingress Controllers (IC) with Linkerd. IC are based on (1) NGINX (2) Envoy (2) HA Proxy. NGINX IC has Mister-Minion model
* security : authz policy, mTLS
* intra cluster URL. So no need to go to LB for intra cluster.
* Gateway API (GW-API) integration
* 1.17 Linkerd has many new features.
* canary deployment
Object Store for Vector DB app
github.com/thotz/python-vectordbapp-ceph
It can search image and text both
it uses RGW bucket and in-memory channel
CR has embedded function
CR is per bucket
CR is matched with milvus collection like, vector dimensions, index type, vector metric, staticjk schema
Data Plane Technologies for Load Balancer
LB has many features
These features are supported by data plane technologies
data plane has many technologies, including open source.
1. eBPF :
2. VPP
- L2-L4 n/w
- graph based network
- fast lookup
DPDK :
- latency reduce by bypassing kernel space
- large page and pool.
1. eBPF - XDP model
2. VPP-DPDK model
KubeCon 2024 India. Keynotes
- Upcoming KCDs
1. April, 2025 at Chennai

- Kubestronaut : Takeoffs begin in 2025. In this announcement, India's map was incorrect.
- Upcoming KubeCon and CloudNativeCon
Hydrabad August 6 to 7 , 2025
LF Networking will be launched in phase 1 under LF India
=============================================================
Takeaway points : Flipkart
Ambient proxy is better. Sidecar cannot scale as per pod's TPS, Fan out etc.
For PaaS Controller is better than Helm to deploy
=============================================================
Takeaway points :
- K8s is everywhere
- Nothing is complete with AI
- Starching the limits of K8s
eBPF
- eBPF programme in C, Rust or other programming languages.
- Compiler converts it to bytecode (obj file)
- Application pass this OBJ to kernel using eBPF library
- Kernel verifies it
- When event happens the program runs
