The ugliest name I have ever heard in the industry that confuses me when pronounced is SASE (sassy). It is a new term, born as a new generation of cloud-based networks are coming online that incorporate SD-WAN and NFV to challenge the old telco cloud. Several years ago, most enterprise applications resided in data centers and enterprise branches, and the staff connected to those data centers. The flow required very strict access to the data center to access enterprise apps and the cloud via the public internet (if needed).

These days application access architecture looks like a blend of connections…


Many Service providers organisations now see DevOps as part of their digital transformation strategy in deploying systems that once were hook into a specific box with a specific silicon that lead into an isolated cultures inside those organiztions, i have my tools and you have yours! Since automation kicked-off it encourages a culture of shared responsibility, transparency, and faster feedback. Yet as the gap between development and operations teams shrinks, so do the processes.

So Git, the most widely used version control system . As service providers embrace DevOps methodologies, so to the tools, which has created an evolution to…


Trust, or the lack of it, is the number one factor that blocks adoption of cloud services provided by OTT’s . Data is the most important asset of any business — data about products, customers, employees, suppliers, and more. Data, of course, is at the heart of the cloud. cloud applications provide customers with centralized, network‐based access to data with less overhead than is possible when using a locally installed application. …


Understanding the underlying topology of data

Im fasinating by machine learnning and started to use in back in 2016 in my previous IOT project when used to train the algorithm i used to make data correlation more accurate and use to that use it as new triggers for actions other IOT devices will get. A new methode caught my eye recently and i decided to deticate a blog post to it.

Topological data analysis (TDA) is an unconventional machine learning technique that is used to understand the underlying topology of data. The premise is that data has shape. The two…


As telecommunications technology transitions from 4G to the incredible promise and potential of 5G, one thing is clear: the new technology is not just an incremental upgrade, but an exponential leap in terms of speed, accuracy, latency and complexity. Indeed, the complicated nature of 5G is both one of its great advantages — allowing incredible next-generation capabilities in automation, robotics, virtual reality and more — and a huge challenge when it comes to safe, secure, successful implementation.

The many elements that comprise and impact a 5G network or application are constantly and quickly changing. That’s largely due to the fact…


Functions on edge — Part 2

So how does FaaS orchestration works and combine simple well-defined serverless functions into more complex applications. A well defined set of constraints that identifies the need of a careful evaluation of trade-offs in function orchestration is essential . Those trade-offs mainly concern the fact that functions should be considered as black boxes, function orchestration should preserve a substitution principle with respect to synchronous invocation, and function invocations should not be double-billed. For example the considered reactive core of OpenWhisk (presented in part 1) is based on events (triggers) which represent a class of topics…


In recent years, Software-Defined Wide Area Networking (SD-WAN) has created a buzz in the networking world. But what about MPLS (Multiprotocol Label Switching)? Has this routing technique been made redundant by the increasing uptake of SD-WAN? What are the differences and similarities between SD-WAN and MPLS? And are there valid reasons to use both?

What is SD-WAN?

Software-Defined Wide Area Networking (SD-WAN) is a software-defined approach toward bringing wide area networking to organizations seeking more diversity and control over their enterprise WAN. SD-WAN incorporates a traditional hardware-based networking model and adds a software-defined virtual network overlay on top. This overlay is managed and…


The idea of applying the serverless paradigm in the edge looks appealing and promising.

Event-based serverless functions are naturally suited to define computation on IoT data, while containerisations are lightweight and can run on most edge devices, on-demand execution of functions can lead to improved usage of resource-constrained devices, closer to the edge of the Internet. However, the adoption of the FaaS in edge scenarios expose the challenge of preserving and enforcing security constraints. Edge comes along with new distinctive security threats to be faced. …


Kubernetes has recently turned heads in the telecom's industry, the Kubernetes.io show several use cases. The system is set to be an intrinsic part of the flexible cloud-native architecture required to bring out the best in 5G networks. A cloud-native network should offer benefits, from rapid deployment of services and automation to much greater resiliency and efficiency.

This kind of flexibility and scalability is fundamental to the telecom cloud vision — the idea that 5G networks will become a versatile platform for a wide range of services and apps developed by third parties. …


We can assume that no service provider will be ready to buy and deploy core network as it is today for the one simple reason — nowadays core networks are monolithic and centric while most OTT cloud infrastructure is distributed and build by using micro-services. Using the old fashion technology simply does not making any sense. Despite the fact that there are several vEPC products in the market, none of them has reached a production stage; most of installations are in labs. Looking forward vEPC will never replace the current EPC install base — the market is already looking for…
