2017 Prediction: The Move Towards Distributed Security Architectures Accelerates

By Nick Tausanovitch | Jan 17, 2017

The rapid evolution of cloud-based data centers to support virtualized services and containerized applications will accelerate in 2017 and beyond. This will necessitate a move away from traditional data center security architectures, which rely mostly on perimeter-based firewalls, to a more distributed security architecture. This is required because in today’s multi-tenant and multi-group environments, individual applications cannot be trusted, the potential for threat injection inside the data center is real, and the resulting damage can be disastrous.

By Sujal Das | Jan 10, 2017

Kernel means many things – such as the softer, usually edible part of a nut, or the seed and hard husk of a cereal, or the central and most important part of something. In the world of Linux, the kernel certainly means the central and most important part of the operating system.

Virtualization of Mobile Networks Sets the Stage for 5G and IoT

By Nick Tausanovitch | Jan 3, 2017

2017 will be the year that virtualization of mobile networks moves from concept to reality. The benefit of using a cloud-based model to implement network functions, also known as network functions virtualization (NFV), has already been broadly accepted by telecom service providers as a key goal. In fact, the cloudification of mobile networks is a foundational underpinning and key architectural paradigm for 5G and IoT networks and is required to implement functions such as dynamic network slicing, for example.

The Case for Express Virtio (XVIO) – Part 2

By Abhijeet Prabhune | Nov 8, 2016

In part 1, my colleague Sujal Das reviewed the operational challenges data center operators spoke about at OpenStack Summit last month. The resounding common theme was poor server infrastructure efficiency. Sujal reviewed the underlying reasons for these challenges starting with a wide variety of VM workload requirements including networking options and CPU requirements.
