About Talks:

Kubernetes Multitenancy

The way most users deploy Kubernetes these days is as fully isolated clusters in a bunch of VMs and assorted resources on some cloud.

Why does this happen? unlike VMs, containers are not secure: cgroups and namespaces are not meant to provide complete isolation. Various efforts exist to solve this issue by deploying tiny VMs for each pod (e.g. Kata containers) and thus benefitting from HW virtualization (vt-x, AMD-v, etc).

Compared to general purpose virtualization projects (e.g. QEMU), we have a narrow set of requirements:

Security first: jails, device process isolation, etc
Passthrough / DDA: no emulation
Performance (the target is to boot pods in < 1s)
Modularity: no monolithic executables

Since no existing project matched them, we started a new one (drumroll...) named Insula (Latin for island and thus isolation), which we will introduce and demo in this session!

Dreaming about Kubernetes for years

Spas will share with us his experience in ReceiptBank with Kubernetes from lab to prod in three directions:

- how we started
- where we are
- where we intend go

In this talk all attendees will see different approaches for:

- using Kubernetes for QA & Demo
- daily dev process in/with kubernetes
- having a production ready kubernetes cluster
