Metal as a Service – MAAS – lets you treat physical servers like virtual machines in the cloud. Rather than having to manage each server individually, MAAS turns your bare metal into an elastic cloud-like resource.

MAAS delivers the fastest OS installation times in the industry thanks to its optimised image-based installer. Setup the RAID and Network configuration you want through the MAAS web UI or CLI, then press a button and come back in minutes to a fully-deployed OS.

MAAS is designed for devOps at scale, in places where bare metal is the best way to run your app. Big data, private cloud, PAAS and HPC all thrive on MAAS. What does that mean in practice? Tell MAAS about the machines you want it to manage and it will boot them, check the hardware’s okay, and have them waiting for when you need them. You can then pull nodes up, tear them down and redeploy them at will; just as you can with virtual machines in the cloud.

When you’re ready to deploy a service, MAAS gives Juju the nodes it needs to power that service. It’s as simple as that: no need to manually provision, check and, afterwards, clean-up. As your needs change, you can easily scale services up or down. Need more power for your Hadoop cluster for a few hours? Simply tear down one of your Nova compute nodes and redeploy it to Hadoop. When you’re done, it’s just as easy to give the node back to Nova.

MAAS is ideal where you want the flexibility of the cloud, and the hassle-free power of Juju charms, but you need to deploy to bare metal.

The following video provides an introduction to MaaS.

The Open Network Operating System (ONOS) is the first open source SDN network operating system targeted specifically at the Service Provider and mission critical networks. ONOS is purpose built to provide the high availability (HA), scale out, and performance these networks demand. In addition, ONOS has created useful Northbound abstractions and APIs to enable easier application development and Southbound abstractions and interfaces to allow for control of OpenFlow ready and legacy devices. Thus, ONOS will bring carrier grade features (scale, availability, and performance) to the SDN control plane,  enable Web style agility, help service providers migrate their existing networks to white boxes , lower service provider CapEx and OpEx. ONOS has been developed in concert with leading service providers (AT&T, NTT Communications), with demanding network vendors (Ciena, Ericsson, Fujitsu, Huawei, Intel, NEC), R&E network operators (Internet2, CNIT, CREATE NET), collaborators (SRI, Infoblox), and with ONF to validate its architecture through real world use cases.

The following video shows an ONOS architectural overview.
