Complexity Sells

Networks are complex. But why? There are two fundamental reasons. The first is complexity is required to solve hard problems, specifically in the area of resilience. The second is that complexity sells. In this short take, I look at the second reason in a little more depth.

Announcing our second year on the Gartner Magic Quadrant for Data Center Networking

We couldn’t be happier to report that Cumulus Networks has been placed on the Gartner Magic Quadrant for Data Center Networking in the Visionaries category — for the second year in a row. This acknowledgement and honor once again solidifies not only our place in the industry, but also open networking’s place as a whole. The report states, “Cumulus continues to pioneer a vision based on open components, disaggregation of switching hardware/software and automation.” We couldn’t agree more, and we’re excited to be driving the industry forward into efficiency, flexibility, simplicity and innovation.

Gartner’s 2018 Magic Quadrant for Data Center Networking gives an assessment of the current data center networking solutions for enterprises, and evaluates where they fall on ability to execute as well as completeness of vision. Without further ado, here is this year’s quadrant:

A few key highlights: 

  • Cumulus was mentioned continually throughout the report in relation to hardware support, enterprise growth and leaders in the disaggregation and open networking movement. Most notably, Gartner highlighted our growth with enterprise customers, which helped us differentiate ourselves on the quadrant from other vendors. The report states, “Cumulus grew its enterprise customer count by more than 200 over the past Continue reading

Clark County Embraces Intrinsic Security with VMware NSX Data Center

Allen Tyson is a Senior Network Analyst at Clark County, located in the State of Nevada. Clark County encompasses the City of Las Vegas, and sees 47 million visitors each year. With roughly 10,000 employees and 38 departments, Allen has a large network to maintain.

Alex Berger, Networking and Security Product Marketing Manager, spoke with Allen about software-defined networking (SDN), and what led Clark County to choosing VMware NSX Data Center.

 

The Power of Social Media Communities

When a forward-thinking Deputy Chief Information Officer began talking about SDN, Allen did his due diligence to decide on the best option for Clark County. He took to social media to determine whether that choice would be NSX Data Center or Cisco ACI.

“First thing I did was I got on Twitter,” Allen explains. “It seemed like NSX was capable of doing a little bit more [than Cisco ACI] and it also seemed like the communities behind NSX and the people who were using NSX and the ability that I had to get a response from people was greater on the NSX side. And so, I started looking more into NSX.”

Allen was looking for stories from other customers with similar Continue reading

Datanauts 142: Cloud-First Networking With Big Switch Networks (Sponsored)

You ve got your traditional on-premises network. You know how it works. Lots of manual configuration and ticket-y stuff to get the job done when someone needs something.

And then you ve got your cloud network. You don t worry about that one as much. The devs provision what they need automatically, hitting APIs as they go, and you keep tabs on things from a watchful distance, helping out as needed.

What if you could operate your on-premises network like you do your public cloud network? What if your hybrid cloud was operationally consistent? Today on the Datanauts, sponsor Big Switch Networks makes some pretty big hybrid cloud networking announcements, and we quiz them on the why and how.

Our guest is Kyle Forster, founder of Big Switch.

We talk about Big Switch’s new products, including the ability to create an on-premises VPC within Big Switch’s data center fabric. The goal is to provide the same operational constructs within your own data center as you’d get in a public cloud like AWS, Azure, or Google.

IETF 102, Day 3: DNSSEC, DPRIVE & IoT

This week is IETF 102 in Montreal, Canada, and we’re bringing you daily blog posts highlighting the topics of interest to us in the ISOC Internet Technology Team. And today’s topics include DNS Security & Privacy, along with more IPv6 and IoT.

The first DNSOP session will start at 09.30 EDT/UTC-4, and will continue on Thursday evening. Topics of interest include a draft on Algorithm Implementation Requirements and Usage Guidance for DNSSEC, which updates current algorithm implementation requirements and usage guidance for DNSSEC (obsoleting RFC 6944). Another draft on Multi Provider DNSSEC models describes how to deploy DNSSEC in environments where multiple DNS providers are in use, whilst Delegation_Only DNSKEY flag introduces a new flag for DNSSEC keys that can address a potential attack.

NOTE: If you are unable to attend IETF 102 in person, there are multiple ways to participate remotely.

Alternatively, the relatively new working group SUIT will also be meeting at the same time. Vulnerabilities in Internet of Things (IoT) devices have raised the need for secure firmware updates that are also suitable for a constrained environments, and this group aims to develop an interoperable update mechanism. There are three drafts up for discussion, including the description of the firmware Continue reading

Web-scale: a healthy choice for healthcare networks

Major cloud providers are able to achieve impressive uptime by distributing the load across a large number of commodity servers. There’s no single master server that can fail and bring down the entire infrastructure. It’s not surprising then that so many healthcare networks are already relying on major cloud providers to run electronic medical records (EMR) and imaging applications and store patient data. So doesn’t it make sense to adopt the same approach for the network?

Healthcare networks face a unique challenge that many other networks don’t: how do you grow your network quickly and reliably while remaining compliant? As patient data grows, this tension between growth and compliance is increasing. Healthcare networks are feeling the pressure to move data faster, and this often requires adding more connections and switches, which entails routing and other configuration changes. These continual and rapid changes come at the cost of long, sometimes unplanned, outages. Planned outages are to be expected, but unexpected outages are a nightmare. Consequently, many healthcare networks have understandably opted for slower network growth to maintain a stable, reliable network.

But thanks to the advent of web-scale networking, the tension between growth and compliance is quickly becoming a thing Continue reading
