What MidoNet Does

MidoNet decouples your IaaS cloud from your network hardware, creating an intelligent software abstraction layer between your end hosts and your physical network.

This network abstraction layer allows the cloud operator to move what has traditionally been hardware-based network appliances into a software-based multi-tenant virtual domain.

MidoNet Enables

  • Reduced complexity of physical network
  • High availability (any server, any network service, any time)
  • Scalability through hierarchy
  • Reduced protocols
  • Optimized network traffic with minimal overhead
  • Vastly improved fault tolerance

You'll gain superior network efficiency, reduced dependence on overworked IT staff, and the agility to respond instantly to changing demands.


  • Virtual L2 Distributed Switching
  • Virtual L2 Isolation
  • Virtual L3 Distributed Routing
  • Virtual L3 Isolation
  • L4 Services (Load Balancing, Firewall)
  • NAT / Floating IP's
  • Access Control Lists (ACLs) and Security Groups
  • Restful API
  • OpenStack integration

MidoNet brings production-grade distributed overlay networking to OpenStack

"Open source has brought incredible innovation and traction to both compute and storage virtualization technologies, while historically, most of what we've seen from the networking space has been proprietary," said Chris Wright, technical director, SDN and NFV, Red Hat. "It is promising that the many benefits of 'open' are now being acknowledged by leaders in that space, and by Midokura announcing plans to open source their network virtualization offering, they are helping to enable the truly open software-defined datacenter."

Chris Wright, Technical Director, SDN and NFV at Red Hat

"Network function virtualization and software-defined networking are buzz words in many corners of the cloud industry. But to our customers, reliable performance of virtualized network fabrics is an essential element of their long-term cloud infrastructure strategy. Working with the Midokura community, we look forward to helping create a new and powerful open source option for our customers."

Mike Yang, general manager, Quanta Cloud Technology (QCT)

"This is another testament that the networking industry is embracing open source as the right path forward for network virtualization and SDN. More open source code means more choice for developers and users and is good for the entire industry. We look forward to seeing how OpenDaylight and the MidoNet project can interoperate to benefit users of any size and scale."

Neela Jacques, executive director, OpenDaylight Project

"Midokura's decision to open source MidoNet fits perfectly in the open future that we at Mirantis believe in. This will be the only open solution that is not driven by a hardware networking vendor and we're excited to be a part of it. We look forward to being an active member of the MidoNet community ongoing."

Boris Renski, Co-Founder and CMO, Mirantis

"We're excited to see Midokura, an early Cumulus Networks overlay partner, join the community and encourage customers to implement and deploy OpenStack solutions. Open Source overlays like Midonet complement the Cumulus Linux networking OS underlay to enable large scale agile network infrastructure"

Nolan Leake, CTO and co-founder, Cumulus Networks

"We are thrilled to be a part of the MidoNet open source project. Midokura and Solinea are both long time contributors to the OpenStack community and this partnership will help bring cloud services and vendor-agnostic network virtualization to the masses."

Ken Pepple, CTO, Solinea

"We are thrilled that Midokura is releasing the source code for MidoNet, helping users worldwide reach their goals of a production-ready cloud. The move to an open source model levels the playing field for Software-Defined Networking, supplying the last piece of the puzzle in the OpenStack ecosystem."

Dag Stenstad, CTO, Zetta.IO

"We are committed to open development and recognize the value open MidoNet can add to the OpenStack community. The availability of an open Software Defined Networks package from Midokura that takes advantage of our ConnectX-3 10/40 Gigabit Ethernet NIC with VXLAN offloads will accelerate the adoption and evolution of network virtualization in OpenStack environments."

Kevin Deierling, vice president of marketing, Mellanox Technologies

"As one of Midokura's early investors, we have been a long time believer and proponent of the MidoNet technology. This open source project is exactly what the OpenStack community needs and we are excited to be a part of it. We can now easily and effectively enhance OpenStack-based clouds with network virtualization."

Takeshi Narisako, executive officer and chief director of cloud & IT solution, Bit-isle inc.

"Midokura is boldly addressing the market need for a production-ready, SDN solution free of vendor lock-in. This is an exciting contribution to the open source community that will accelerate private cloud adoption. We are thrilled to offer Eucalyptus users AWS compatible hybrid cloud solutions with true VPC support, powered by MidoNet."

Shashi Mysore, VP Products, Eucalyptus

"IDC Frontier is very much pleased that MidoNet goes open-source. We believe this will attract more users who are avoiding vendor lock-in to MidoNet, which has rich experiences with network virtualization. We also believe this will further expand its user community and accelerate the process of function enhancement. This will bring benefits to cloud service providers like IDC Frontier both in technical and business perspectives, as well as abilities to provide high quality services to their customers. I am hoping MidoNet becomes the de facto standard of network virtualization someday."

Masaki Hayashi, Director of Technology Development Div., IDC Frontier Inc.
