Canonical CEO Jane Silber to Step Down in 3 Months
Canonical is putting its focus on cloud and IoT.
The emergence of software-defined application delivery technology – and what it can do for your network
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
The flexibility of the cloud has driven IT to look closely at opportunities to replicate that agility in their own infrastructure and operations. Automation initiatives have optimized many layers of the computing stack, but application delivery services remain a last-mile problem as network teams find themselves hamstrung by inflexible legacy architectures.
While virtual appliances for load balancing, long thought of as the answer for software-driven infrastructure, have existed since the advent of virtualization, they inherit most of the architectural challenges of legacy solutions, including limited scalability, lack of central management and orchestration, and performance limitations. Instead, what is needed is an application delivery architecture based on software-defined principles that logically separates the control plane from the data plane delivering the application services.

The AI revolution: Is the future finally now?
Over the last several decades, the evolution of artificial intelligence has followed an uncertain path – reaching incredible highs and new levels of innovation, often followed by years of stagnation and disillusionment as the technology fails to deliver on its promises.
Today we are once again experiencing growing interest in the future possibilities for AI. From voice powered personal assistants like Google Home and Alexa, to Netflix’s predictive recommendations, Nest learning thermostats and chatbots used by banks and retailers, there are countless examples of AI seeping into everyday life and the potential of future applications seem limitless . . . again.

VMware cloud design decisions: LACP part 1
Recently I’ve been helping a customer who’s working on a VMware cloud design. As is often the case, there are a set of consulting SME’s helping with the various areas; an NSX/virtualization consultant, the client’s tech team and a network guy (lucky me).
One of the interesting challenges in such a case is understanding the background behind design decisions that the other teams have made and the flow-on effects they have on other components. In my case, I have a decent background in designing a VMware cloud and networking, so I was able to help bridge the gap a little.
My pet peeve in a lot of cases is the common answer of “because it’s ‘best-practice’ from vendor X” and a blank stare when asked: “sure, but why?”. In this particular case, I was lucky enough to have a pretty savvy customer, so a healthy debate ensued. This is that story.
Disclaimer: What I’m going to describe is based on network switches running Cumulus Linux and specifically some down-in-the-weeds details on this particular MLAG implementation. That said, most of the concepts apply to similar network technologies (VPC, other MLAG implementations, stacking, virtual-chassis, etc.) as they operate in very Continue reading
Cloudflare Rate Limiting – Insight, Control, and Mitigation against Layer 7 DDoS Attacks
Today, Cloudflare is extending its Rate Limiting service by allowing any of our customers to sign up. Our Enterprise customers have enjoyed the benefits of Cloudflare’s Rate Limiting offering for the past several months. As part of our mission to build a better internet, we believe that everyone should have the ability to sign up for the service to protect their websites and APIs.

Rate Limiting is one more feature in our arsenal of tools that help to protect our customers against denial-of-service attacks, brute-force password attempts, and other types of abusive behavior targeting the application layer. Application layer attacks are usually a barrage of HTTP/S requests which may look like they originate from real users, but are typically generated by machines (or bots). As a result, application layer attacks are often harder to detect and can more easily bring down a site, application, or API. Rate Limiting complements our existing DDoS protection services by providing control and insight into Layer 7 DDoS attacks.
Rate Limiting is now available to all customers across all plans as an optional paid feature. The first 10,000 qualifying requests are free, which allows customers to start using Continue reading
