Comments on Vendor Optics – Listen Here

I recently listened to Packet Pushers show 395 recently. It is a great discussion on optical networking. One thing I wanted to make everyone aware of was a series of comments on the varying quality of optics and some justification around the premium prices often found on vendor branded optics. While the entire episode is worth a listen, the discussion around vendor optics begins at about 35:20 into the recording.

I work for a vendor and it is doubtful that people would view my opinion as unbiased. I encourage everyone to take a listen below and form their own opinions.

If you are a tech guy or girl, the Packet Pushers Podcast is a perfect addition to the podcatcher.

Most Enterprise of Things initiatives are a waste of money

The Internet of Things (IoT) has captured much attention recently as more devices like wearables, AR/VR headsets and sensor-based products make their way to market. But off-the-shelf consumer-oriented devices are not always what enterprises need. Rather, most companies need a more specialized approach than just deploying things all over the place.As a result, the more specialized Enterprise of Things (EoT) is becoming a significant part of nearly all companies' plans for the next three to five years. Indeed, we expect EoT to become a top 3 item on most organizations' strategic initiatives in the coming two to three years. EoT will partner with ongoing enterprise cloud and security initiatives as organizations look to transform how they do business and run more efficient and user-responsive operations. But research shows that for many companies currently deploying or planning deployments of EoT, it’s a waste of money.To read this article in full, please click here

Jabil Enables a Global Software Supply Chain with Docker Enterprise Edition

Jabil, one of world’s most technologically advanced manufacturing solutions provider with over 100 sites in 29 countries is embarking on a digital journey to modernize their technology infrastructure so the company is better able to deliver the right solutions at the right time to their global customer base.

 

Starting the Digital Journey By Modernizing .NET Apps 

As Jabil embarked on their digital journey with a cloud-first approach in mind, they investigated how to best migrate their applications to the cloud. Jabil partnered with Docker and Microsoft to leverage Docker Enterprise Edition with Windows Server 2016 and Microsoft Azure for this initiative through Docker’s Modernize Traditional Application (MTA) Program – starting with  a .NET 4.5 monitoring application to containerize.

Since completing the initial POC, Jabil has continued containerizing more applications and has started scaling their Docker Enterprise usage globally. Sujay Pillai, a Senior DevOps Engineer at Jabil, participated at DockerCon SF 2018 in June and shared with the attendees insights on how Jabil is scaling Docker Enterprise Edition.

Improving Application Security while Reducing Costs at the Edge

One growing use case for Jabil is monitoring of the manufacturing floors. Jabil uses lightweight edge devices to run the monitoring Continue reading

Like Watching the Caveman Invent the Rock – Cisco “Discovers” Software

In truth, today’s legacy enterprise networks — many now decades overdue for replacement — were built to fight Cold Wars among the vendor powers.  Cisco “big iron” battled Wellfleet “big iron” and, later, Juniper “big iron,” and the throughput/density contests are now the stuff of NetOps legend.  But these aging networks are completely ill-suited to fight today’s data-oriented guerilla warfare, where hackers, DevOps, IoT, mobile, open source, and cloud services clamor for attention and have NetOps IT people desperately trying to manage an environment that feels more like a third-world airport terminal flooded with people fleeing a coup than a predictable business utility.

To be fair, Cisco was able to successfully weaponize account control far better than Juniper, Extreme, et al, so they ended up “winning” – and keeping — the large enterprise business to the tune of some 80 percent market share.  But this business stranglehold can no longer be defended by the moral equivalent of a proprietary Maginot Line.  The new name of the networking guerilla warfare game is software.  The new “best practice?” — disaggregated Linux-based open white box switching with a full enterprise feature set – one that is future-proofed with Continue reading

Recent BGP Peering Enhancements

BGP is one of the foundational protocols that make the Internet “go;” as such, it is a complex intertwined system of different kinds of functionality bundled into a single set of TLVs, attributes, and other functionality. Because it is so widely used, however, BGP tends to gain new capabilities on a regular basis, making the Interdomain Routing (IDR) working group in the Internet Engineering Task Force (IETF) one of the consistently busiest, and hence one of the hardest to keep up with. In this post, I’m going to spend a little time talking about one area in which a lot of work has been taking place, the building and maintenance of peering relationships between BGP speakers.

The first draft to consider is Mitigating the Negative Impact of Maintenance through BGP Session Culling, which is a draft in an operations working group, rather than the IDR working group, and does not make any changes to the operation of BGP. Rather, this draft considers how BGP sessions should be torn down so traffic is properly drained, and the peering shutdown has the minimal effect possible. The normal way of shutting down a link for maintenance would be to for administrators to shut Continue reading

IDG Contributor Network: 4 considerations when replacing managed WAN services with SD-WAN

The enterprise wide area networks are mission-critical resources for most enterprises. And when it came to managing and running the WAN, enterprises could choose between two distinct models: Do it Yourself (DIY) or managed WAN services. But with the evolution of SD-WANs, we’re seeing a new type of telco solution that merges elements of both capabilities.Traditional WAN management models With DIY, enterprise IT procures last-mile access at a location and deploys routers, WAN optimization, and network security appliances from several vendors. Continuous monitoring and management is done in house or via a managed service provider. In short, enterprise IT owns the complex task of maintaining, configuring and monitoring the WAN for availability and optimal performance.To read this article in full, please click here

Complexity Sells

According to Roman philosophers, simplicity is the hallmark of truth. And yet, networks have become ever more complex over time. Why is this? Because complexity sells. In this short take, I talk about why complexity sells, and some of the mental habits you can use to overcome our natural tendency to prefer the complex.
