CTO's comments about the latest article

As part of the transition to 5G, equipment vendors and telecom operators alike are looking to DevOps as a tool to improve their competitiveness, by reducing feature delivery cycles and boosting feature hit rates through feedback loops, for example. DevOps helps companies strike the right balance between change and stability by extending the agile software development culture to deployment and operations.

The latest Ericsson Technology Review article presents the outcome of our efforts to define DevOps for next-generation telecom networks by scaling DevOps in the OPNFV project and working with academic partners. These fruitful collaborations have resulted in a reference DevOps pipeline for a 5G business slice and a DevOps approach to supporting one of the most important aspects of virtualized infrastructure in 5G networks: elasticity.

DevOps: fueling the evolution toward 5G networks

April 21, 2017

DevOps – an interactive approach to product management, development, deployment and operation – has an important role to play in helping equipment vendors and telecom operators meet 5G requirements. In light of this, Ericsson has worked closely with open source communities such as OPNFV and academic partners to define DevOps as it applies to next-generation telecom networks, identifying the specific steps of the DevOps cycle that are most relevant for 5G infrastructure. This work has resulted in the creation of a DevOps reference pipeline for a 5G business slice, as well as processes and advanced features supporting dynamically software-defined network functions and infrastructure.

Tackling IoT complexity with machine intelligence

April 6, 2017

IoT-based systems will require a high level of decision making automation both in terms of infrastructure management and within the logic of the IoT applications themselves. Decision support systems (DSSs) are an essential tool in this context on account of their ability to enhance human decision-making processes with machine intelligence. The cognitive automation framework that we have created at Ericsson speeds up the development and deployment of intelligent DSSs by reusing as much knowledge as possible, including domain models, behaviors and reasoning mechanisms. The framework substantially reduces operational costs for IoT-based system management by enabling DSSs to make decisions about how to adapt to changes in their context and environment with minimal or no human interaction.

Securing the cloud with compliance auditing

Securing the cloud with compliance auditing

March 22, 2017

To gain and retain user trust, cloud providers must be able to deploy tenants’ applications, store their data securely and ensure compliance with multiple regulations and standards. Security compliance auditing is the obvious solution, but several challenges related to the particular specificities of the cloud are limiting the potential benefit of applying current auditing practices and tools. Moving toward a continuous automated compliance verification model that provides tenants with complete compliance visibility is the key to successfully managing security risks in the cloud.

CTO's editorial for latest magazine

The latest issue of Ericsson Technology Review presents a wide range of ideas and solutions that boost capacity, efficiency and security, as well as the latest technology to help you better understand the needs of your users. It also features an article by guest writer Stefan Larsson, associate professor in technology and social change at Lund University Internet Institute.

Dr. Larsson is an expert on digital socio-legal change, including issues of trust, consumption, traceability and privacy. He argues persuasively that the long-term success of the digital economy will be dependent on consistently high levels of both technological and sociological trust among users, and explains his view of what service providers must do to preserve them.

As always, I hope you find the contents of the magazine relevant and inspiring. All of the articles included in this issue are available individually on our website, through the Ericsson Technology Insights app and on SlideShare. Please feel free to share them via e-mail or social media.
