AT&T, IBM bring cloud-to-cloud connectivity down to minutes #telcocloud

AT&T Labs, IBM Research and consultancy Applied Communication Sciences (ACS) said this week they have seen the culmination of a project that started out as a hypothetical network study in 2007, resulting in a real-world, proof-of-concept this May.

The technology, co-developed under the US Government’s DARPA CORONET program, aims to bring cloud and data centre interconnectivity into a more dynamic, elastic state, taking cloud-to-cloud setup times down to minutes from days or even weeks.

The shift relies heavily on software defined networking (SDN) developments to create a smart network that AT&T imaginatively calls the User-Defined Network Cloud (UDNC). A key area it will impact is cloud-to-cloud connectivity. As AT&T explained, when using a traditional network model, the connection between clouds is static – meaning it can’t expand or contract based on the need for bandwidth. Moreover it has traditionally been labour-intensive, expensive and time-consuming to set up these cloud-to-cloud connections.

The carrier believes that as the cloud’s potential grows, the networking between the datacentres – or clouds themselves – needs to be similarly dynamic. So, the proof-of-concept technology can set-up a cloud-to-cloud connection in under a minute. “This prototype uses just the right amount of bandwidth, and can enable setup times as short as 40 seconds, compared with the previous setup time of several days,” AT&T said.

Why is this important? The developers use the example of an emergency situation. Imagine a hurricane is headed toward a datacenter. Ideally an operator would quickly provision enough bandwidth to transfer all that data to another datacentre. While not possible before, this proof-of-concept technology makes it achievable. But in the future, the use of flexible, on-demand bandwidth for cloud applications – such as load balancing, remote datacentre backup operation, and elastic workload scaling – will provide major service flexibility and efficiencies for businesses.

Researchers at IBM labs revealed a related development back in December, with a technology that allows for the storing and moving of data across multiple cloud platforms in real time. IBM said the method for dynamic data migration and backup uses a “cloud-of-clouds” approach, a multi-cloud distributed storage system that can link data in over 20 different public and private clouds.

Researchers at the company have developed a software toolkit that lets users drag and drop block or file storage across almost any cloud platform, with little data replication. The development avoids service outages because it can tolerate crashes of any number of clients, using the independence of multiple clouds linked by a distributed storage algorithm to increase overall dependability.

The storage services don’t talk to one another directly but instead go through the cloud service for authentication and storage synchronisation; data is encrypted as it leaves one storage platform and decrypted before reaching the next. If one cloud fails, the back-up immediately responds.

Alcatel, Fujitsu join AT&T’s cloud-focused network architecture effort

Alcatel-Lucent and the networking communications arm of Fujitsu have joined AT&T’s ‘User-Defined Network Cloud’ programme, the telco’s bid to rearchitect its core network in a move that will make it more elastic, scalable, and capable of handling massive volumes of IP-based traffic.

Earlier this year AT&T announced a bold move to embrace software defined networking (SDN) and network function virtualisation (NFV) in its core network because of the changes it has foreseen in how customers will use its network.

Underpinning this is the company’s ‘Domain 2.0’ effort, an initiative that sees key vendors like Ericsson and Juniper working with AT&T to develop the underlying technology platform allowing network services and infrastructure to be used, provisioned, and orchestrated like a cloud platform.

As part of the announcement both Alcatel-Lucent and Fujitsu will join in the effort to develop the Domain 2.0 platform.

“The architecture and deployment teams are finalizing their planned introduction of this new architecture, which we expect to roll out later this year and early 2015,” said Tim Harden, president, AT&T Supply Chain.

“We look forward to collaborating with Fujitsu and Alcatel-Lucent to achieve our next-generation network.”

The Domain 2.0 platform is a direct response to both actual and forecast growth in cloud services uptake among AT&T’s customers; legacy networks simply aren’t dynamic, flexible or scalable enough to keep up with the growth in IP-based traffic.

“The rapid growth in IP endpoints requires greater scale and efficiency in handling the number and diversity of devices than we are getting from traditional network solutions. Movement of data to the cloud for use on any device and increasing use of virtual machine models redefines the endpoints and timeframes for provisioning network connections. These drivers require the business of networking to significantly improve the capital efficiency and human operations per unit of business,” the operator said.

“It will allow AT&T and our customers to share a common pool of resources (& CAPEX) and to use those resources in order to compose network capabilities and services on-demand, with elasticity, and driven with orchestration techniques similar to those seen managing the workloads in cloud datacentres.”

AT&T said other benefits associated with its network overhaul include better utilisation of physical assets, more flexibility with customers, greater access to a wider range of suppliers and open source technologies

According to research, IT Practitioners don’t seem to understand SDN yet.

However, all evidence highlights that enterprises must take the opportunity to manage the speed of change made possible by the virtualisation of other data centre resources and provide the perfect complement to cloud computing.

Recognising the unity between network virtualisation, cloud and enterprises, the Cloud World Series is pleased to bring the timely Software Defined Enterprise Forum.

Confronting the difficulties Enterprise IT experts and vendors face when grasping the SDN momentum, the two day conference agenda brings key case studies and best practice from those already ahead of the Software Defined Networking, Storage and Datacenter game!
