Open Source Projects at LinuxCon + ContainerCon + CloudOpen China

LinuxCon + ContainerCon + CloudOpen China (LC3) will take place in Beijing next week, June 19-20. The event offers attendees the opportunity to collaborate, share information and learn about new and interesting open source technologies. Attendees to this year’s conference can examine how Linux, containers, the cloud, networking, and microservices can work with open sources technology. Attendees will also learn how to navigate and lead in the open source community.

We’re excited to be part of this great open source event, with experts from our technical teams contributing to four unique sessions and our open source team from the Harbor project onsite at the VMware booth. The team will be showcasing Harbor, Admiral and Clarity – stop by and learn how to become part of our thriving open source community.

Here’s what’s on our agenda:

The Open vSwitch and OVN Projects
When: Monday, June 19 at 13:35 – 14:05
Experience level: Beginner
Who: Justin Pettit, Lead Developer, Open vSwitch & OVN, VMware and Ben Pfaff, Principal Engineer, VMware

About: Open vSwitch (OVS) is a multilayer open source virtual switch. OVS is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces. OVN is a new network virtualization project that brings virtual networking to the Open vSwitch user community. OVN includes logical switches and routers, security groups and L2/L3/L4 ACLs, implemented on top of a tunnel-based overlay network.

In this presentation, you’ll receive an overview of the current state of the projects and future plans, such as:

  • The current state of the Linux, DPDK and Hyper-V ports
  • A status update on a portable BPF-based datapath
  • The latest stateful and OpenFlow features available in OVS
  • Performance and debugging enhancement to OVN
  • OVN features under development such as ACL logging and encrypted tunnels

Unikernelized Linux
When: Monday, June 19 at 15:35 – 16:05
Experience level: Intermediate
Who: Tiejun Chen, Staff Engineer, VMware

About: Unikernel is a novel software technology that links an application with the operating system (OS) in the form of a library and packages them into a specialized image that facilitates direct deployment on a hypervisor. Comparing to the traditional virtual machine (VM) or the recent containers, Unikernels are smaller, more secure and efficient, making them ideal for cloud environments. There are many open source projects like OSv, Rumprun and so on. But why haven’t these existing unikernels gained mass popularity? We think Unikernels are facing three major challenges:

  1. Compatibility with existing applications.
  2. Lack of production support (e.g. monitoring, debugging, logging).
  3. Lack of compelling use case.

In this presentation, you’ll learn about our investigations and exploration of how we can convert Linux as Unikernel to eliminate these significant shortcomings, plus some explorations of coordinating and cooperating with hypervisor.

Efficient and Secure Container Image Management in Enterprise
When: Tuesday, June 20 at 11:00 – 11:30
Experience level: Intermediate
Who: Haining Zhang, VMware

About: As container technology becomes widely adopted in the industry, containerized applications pose new challenges to administrators. The management challenges come from two aspects: the dynamic container runtime and the static container images.

In this presentation, you’ll learn how to address the management of container images and evaluate the challenges to enterprises. We will discuss how to manage container images efficiently and securely to meet the need of enterprises. Challenges to be addressed include Role Based Access Control (RBAC) of images, image consistency, large scale image distribution, image replication and promotion and high availability of registry.

The open source registry Harbor will be introduced as part of the solution to these challenges.

The Business Reality of Building Open Source: What We Learned from OVS and OVN
When: Tuesday, June 20 at 11:00 – 11:30
Experience level: Any
Who: Justin Pettit, Lead Developer, Open vSwitch & OVN, VMware and Ben Pfaff, Principal Engineer, VMware

About: A number of questions commonly arise in supporting open source projects within companies that primarily develop closed source software, such as:

  • How many resources should we allocate?
  • Are we just enabling our competitors?
  • What, if anything, should we keep proprietary?
  • What are the implications of the license being used?
  • What should we expect in terms of community contributions?
  • How do we balance the needs of the community versus the company?

As founding members of the Open vSwitch and OVN projects, the presenters helped answer these questions at both an early stage startup and a large established company. In this presentation, you’ll learn how they’ve navigated the often-conflicting goals of open source projects and our companies.

You can also find VMware’s Harbor team onsite at the VMware booth. Stop by to learn more about Harbor, Admiral and Clarity and become part of our growing open source community.
