F5 makes agile move with $670 million NGNIX acquisition

App security outfit F5 is buying open-source application platform specialist NGINX to augment its multi-cloud offering.

F5 is hardly the first to notice the importance of the cloud in the evolution of the entire tech industry, nor is it unique in realising that open-source is a great way of making a multi-cloud environment work. But for a company of its size (revenues of $563 million in 2018) this certainly qualifies as putting your money where your mouth is.

“F5’s acquisition of NGINX strengthens our growth trajectory by accelerating our software and multi-cloud transformation,” said François Locoh-Donou, CEO of F5. “By bringing F5’s world-class application security and rich application services portfolio for improving performance, availability, and management together with NGINX’s leading software application delivery and API management solutions, unparalleled credibility and brand recognition in the DevOps community, and massive open source user base, we bridge the divide between NetOps and DevOps with consistent application services across an enterprise’s multi-cloud environment.”

“NGINX and F5 share the same mission and vision,” said Gus Robertson, CEO of NGINX. “We both believe applications are at the heart of driving digital transformation. And we both believe that an end-to-end application infrastructure – one that spans from code to customer – is needed to deliver apps across a multi-cloud environment. “I’m excited to continue this journey by adding the power of NGINX’s open source innovation to F5’s ADC leadership and enterprise reach. F5 gains depth with solutions designed for DevOps, while NGINX gains breadth with access to tens of thousands of customers and partners.”

Open source and DevOps are often referred to in the same breath as part of a broader narrative around ‘agility’. One of the main benefits of the move to the cloud is the far greater choice, efficiency and flexibility it promises, but without a culture geared towards exploiting those opportunities they’re likely to be wasted. With this acquisition F5 is positioning itself as a partner for telcos heading in an agile direction.

Here’s a diagram outlining the rationale of the move.


Telecoms.com Annual Industry Survey 2018

Welcome to the 2018 edition of the Telecoms.com Intelligence Annual Industry Survey report. The findings from our signature survey continue to provide insights and foresight into the dynamic telecoms industry.

Once again well over 1,000 industry professionals from a broad array of backgrounds responded to the survey with their first-hand experience as well as their perspective views on the current status and future trends of the industry. As our customary practice, the report started with an overall industry landscape before we delved into six key areas pertinent to today’s telecoms industry: NFV, 5G, IoT, Digital Transformation, Security, and Test & Monitoring.

A few key findings from the survey:

  • 75% felt positive about the telecoms industry’s business outlook for 2019
  • 79% believed NFV is critical to their companies overall strategy
  • 61% believed emerging technologies and services are critical to telecom’s long-term success
  • 75% saw digital transformation as very important

Conquering video: overcoming the congestion conundrum

Telecoms.com periodically invites third parties to share their views on the industry’s most pressing issues. In this piece Raffaele D’Albenzio, Solution Architect at F5 Networks, looks at ways CSPs can counter the challenges posed by increased video consumption in a cost-effective way.

Video is fast emerging as the Holy Grail for mobile operators and the numbers don’t lie. Facebook users consume eight billion videos a day and 82% of those active on Twitter view video content. Significantly, 90% of Twitter video views and 60% of YouTube views are now from users on mobile devices.

The video bonanza is partly fuelled across the industry by ambitious service providers offering zero rating approaches or aggressively priced unlimited data plans. For example, mobile network Three announced in July plans to include unlimited video streaming for free as part of some contracts. This has been further complicated by ethical debates about the management of network traffic by major operators, as regulators seek to uphold net neutrality. In this context, intelligent traffic management is key for mobile network operators adapting to a landscape with no scope to relax customer service standards.

The majority of mobile video has two main characteristics: encryption via SSL (or similar protocols) and the fact that it is based on Adaptive Bit Rate (ABR) technology, which changes video resolution depending on available bandwidth. Although encryption is a key security feature, it can hinder the ability of operators to maintain a high-quality user experience, as the encryption protocols used by video providers such as Netflix and YouTube can prevent data optimisation using standard traffic management tools. To counter the challenges posed by increased video consumption in a cost-effective way, service providers must look to improve the way Transmission Control Protocol (TCP) works on the mobile network.

TCP is the key transport protocol of internet infrastructure; the glue which, together with Internet Protocol (IP), ensures that all applications connect smoothly to our devices. It allows us to share resources with billions of people all over the world at the same time. It also establishes and manages traffic connections and congestion while taking care of transmission errors.

Today, the ability to detect video streams and manage them using TCP-Proxy-based bandwidth controls or Shaping Capabilities for User Datagram Protocol-based video streams can have a profound impact. It enables service providers to adapt and reduce the amount of bandwidth used by video streams, while continually safeguarding the user experience. Looking ahead, TCP optimisation will become increasingly important to service providers by significantly improving download performance by signal strength on faraway networks

Furthermore, TCP optimisation also allows mobile operators access to radio-centric congestion control algorithms, that adapt to the idiosyncrasies of specific networks. These algorithms are vital conduits to improve traffic flow and the overall user experience. Techniques such as these can also decrease the time between client and TCP termination, enabling both sides to react quickly in the instance of isolated losses or congestion events in the network. Furthermore, it is possible to decrease retransmissions to improve radio resource efficiency.

TCP has many moving parts, with new ones being added every day. Making sense of it all without proper fine-tuning is ill-advised. It is crucial for decision-makers to choose a TCP stack that encompasses high goodput and minimal buffer bloat, as well as allowing for fairness between flows. In the era of mass video dissemination and usage, the TCP must be more than a static bolt-on. Integration with other functionalities — including deep packet inspection, traffic steering, and load balancing — is essential.
