SDN for transport networks — Layer 0 and Layer 1 —is easy to talk about, but real-life 100G and ROADM networks have a lot of complexity to consider. Finding

SDN and NFV can pave the way to heavier automation and a software-defined infrastructure. But that road is full of obstacles related to visibility, security, and the language used

Online shopping platform Wanelo brings together more than 10 million registered users and 200,000 stores. After Wanelo moved to the cloud, it needed a way to manage configuration —

Extending the argument about how NFV can help mobile virtual network operators (MVNOs), we look at how Amazon- or Google-sized MVNOs, in turn, could apply big data to generate

Implementing NFV in the wireless network could bring previously unheard-of levels of visibility and control into the MVNO market by giving wireless-service resellers a piece of the network to

DevOps relies on workflow automation to support evolving software function and programming. At the heart of automation lies standardization: the ability to meet demand, maintain a standard, and be

DevOps tools are just the tip of the iceberg. Agile software development, one of the most critical methodologies in DevOps, relies on people, culture, processes, and tools to establish

For most networking professionals getting familiar with DevOps, the tooling framework consists primarily of deployment and provisioning tools like Chef and Puppet. But the continuum of DevOps tools spans

While it's clearly not a conceptual requirement to implement SDN and NFV together, the technologies complement one another and work well together in supporting a software-defined data center.

Folks at Chef get a firsthand look at how companies get good at building awesome stuff. Here are some of the traits they've observed that lead to DevOps success

The Internet of Things (or Internet of Everything) looms large when you consider the challenges CIOs will face in the next five to 10 years. Facing that challenge will

Network Functions Virtualization offers a key solution by delivering an alternative platform to create services and applications on flexible network architectures. However, if the proper software architecture is not

Changes such as NFV won't allow telecom to sacrifice fundamentals such as high availability. But NFV does give us an opportunity to rethink some principles of the network, starting

SDN really can help a telco go green. When we talk about managing the carbon footprint and keeping energy costs low — for example, in the diesel-fueled mobile networks

While there are many ways to execute configuration management, implementing infrastructure and application delivery automation as code is a key first step. In this DevOps post, we take a

Orchestration can be the key to reconciling a carrier's legacy OSS/BSS platforms with newer NFV deployments. However, the needs of development and test organizations call for a particular type

Surrounded by mystery and controversy, and dogged by apathy, DevOps is a bit misunderstood. Really, it's about taking some well established principles of software development and applying them to

A DevOps methodology can result in a more resilient development environment. The testing of network changes, for example, could be moved away from a brute-force routine to something more

Whether it’s Domain 2.0 or a new enterprise SDN, large network projects face many impediments to success. Here's what AT&T's former CTO suggests you do about it.

Pay-per-use models aren't practical for many mobile operators due to the operational complexity involved. Here's how a service-aware network using SDN and NFV could help.

Are you a 3:00 a.m. network-configuration hero? Your organization will still need you after transitioning to DevOps, but the DevOps culture produces a different kind of hero — and

DevOps is about the expression of the system as source code. But networking does not have universal, vendor-agnostic descriptions for VLANs or even routes. Abstractions play a key role

A peek inside the structure of NFV shows that it's primed to be deployed quickly by carriers. That's partly due to ETSI's guidance, but also due to the fact

DevOps is a hot topic in networking these days, but the movement is young, so many people still do not understand exactly what it is or why it’s important.
