Becoming an AWS Certified Solutions Architect Associate

Architecting for the cloud is becoming a highly desired skill set. Working as a consultant, I’m often in situations where clients are overwhelmed with questions about the cloud. How do I migrate my applications? How do I secure everything? How does it integrate with LDAP and DNS? What’s the best way to connect to the […]

On the ‘net: EVPN Use Cases

In the final session of this video series, we talk to industry experts and RFC authors about additional challenges for which EVPN-VXLAN is a strong answer: Connecting domains (DCI, Campus to DC connections, Multi-vendor networks), multicasting for use cases like live TV streaming, public cloud connection, and other super powers. Join us to find out why these expanded use cases make your lives easier and why your CTO will want to hear more about it to equip your business for rapid responses to new application needs.

BrandPost: Breaking Down the Barriers Between IT and the Network

One of the great challenges with automation in the telecom industry is that the networking and IT domains remain heavily siloed in many service providers today, with hundreds or even thousands of manual processes required to map data from Operation Support Systems (planning, fulfillment, assurance, etc.) to network management and orchestration systems. Not only does this lead to a lot of “swivel-chair” operations to bridge the gap, but fragmented data systems reduce the visibility into real-time service and network state. The quick fix is to over-provision network resources to cope with this lack of visibility, but that leads to unnecessarily high Capex in addition to the Opex overhead associated with highly manual operations.To read this article in full, please click here

Live video just got more live: Introducing Concurrent Streaming Acceleration

Live video just got more live: Introducing Concurrent Streaming Acceleration

Today we’re excited to introduce Concurrent Streaming Acceleration, a new technique for reducing the end-to-end latency of live video on the web when using Stream Delivery.

Let’s dig into live-streaming latency, why it’s important, and what folks have done to improve it.

How “live” is “live” video?

Live streaming makes up an increasing share of video on the web. Whether it’s a TV broadcast, a live game show, or an online classroom, users expect video to arrive quickly and smoothly. And the promise of “live” is that the user is seeing events as they happen. But just how close to “real-time” is “live” Internet video?

Delivering live video on the Internet is still hard and adds lots of latency:

  1. The content source records video and sends it to an encoding server;
  2. The origin server transforms this video into a format like DASH, HLS or CMAF that can be delivered to millions of devices efficiently;
  3. A CDN is typically used to deliver encoded video across the globe
  4. Client players decode the video and render it on the screen

And all of this is under a time constraint — the whole process need to happen in a few seconds, or video experiences Continue reading

Will 5G be the first carbon-neutral network?

If wireless networks transfer 1,000 times more data, does that mean they will use 1,000 times more energy? It probably would with the old 4G LTE wireless technologies— LTE doesn’t have much of a sleep-standby. But with 5G, we might have a more energy-efficient option.More customers want Earth-friendly options, and engineers are now working on how to achieve it — meaning 5G might introduce the first zero-carbon networks. It’s not all certain, though.[ Related: What is 5G wireless? And how it will change networking as we know it ] “When the 4G technology for wireless communication was developed, not many people thought about how much energy is consumed in transmitting bits of information,” says Emil Björnson, associate professor of communication systems at Linkoping University, in an article on the school’s website.To read this article in full, please click here

Stop the Low-Level Configuration Manipulation

Imagine a small bank deciding in their infinite wisdom (in reality: because their CIO attended a conference organized by a database vendor) to implement their banking software by teaching bank tellers how to type SQL transactions by hand.

For example, to transfer money from one account to another account, a bank teller could simply type:
