## Building resilient systems inside the mesh: abstraction and automation of Virtual Service generation Vladimir Georgiev, Thought Machine ## I stioCon ## Sync calls failures inside the mesh - Everyone All Service Owners must be aware of the Virtual Services API in order to define their SLOs. - Potential typing errors when dealing with YAMLs. - Potential drift between the state of the service API and and the Virtual Service config. - Hard to manage when having hundreds of services. ## Abstracting to proto files syntax = "proto3"; package sla; import "google/protobuf/descriptor.proto";

## Debugging the BPF Virtual Machine eBPF Summit ## Why? ● Debugging is useful to understand how things work ● Sometimes, eBPF programs can’t even load - I couldn’t find good resources on this, so so, here I am ● I break lots of eBPF programs - The BPF Virtual machine is not easy to understand ## The approach ## The BPF subsystem lives in the kernel ![Image](/uploads/documents/7/1/6/1/7161fc3

Since CPU architectures are mentioned, I'd expect to see deep slowdown - gcc Intel  Virtual vs. Concrete Run Times - gcc Intel ![Image](/uploads/documents/1/0/9/2/1092c89fc888067fdbc59ca7369237f9/p14_1

## I s Your Virtual Machine Really Ready-to-go with Istio? Kailun Qin, Intel Haoyuan Ge ## I stioCon Quick Summary (from Google Cloud Next '19 [1]) ## V M works on Istio! ## Why Add VMs to the the Mesh? ## ☑ = Why Service Mesh? O More services = more complexity O Need consistent policy enforcement O Need consistent metrics aggregation ## ☑ Traffic management O Load balancing for VMs, failover Deterministic workloads with strong requirements ## For Istio O What is Istio? A service mesh. But more: an open service platform! O More use cases! O (Consul, Kuma...) #IstioCon ## Emerging Use Cases
