Dell EMC and Cisco renew converged infrastructure alliance

Dell EMC and Cisco have renewed a collaboration on converged infrastructure (CI) products that has run for more than a decade, even as the momentum shifts elsewhere. The news was announced via a blog post by Pete Manca, senior vice president for solutions engineering at Dell EMC.The deal is centered around Dell EMC’s VxBlock product line, which originally started out in 2009 as a joint venture between EMC and Cisco called VCE (Virtual Computing Environment). EMC bought out Cisco’s stake in the venture before Dell bought EMC.To read this article in full, please click here

Rapid Development of Serverless Chatbots with Cloudflare Workers and Workers KV

Rapid Development of Serverless Chatbots with Cloudflare Workers and Workers KV

Rapid Development of Serverless Chatbots with Cloudflare Workers and Workers KV

I'm the Product Manager for the Internal Tools team here at Cloudflare. We recently identified a need for a new tool around service ownership. As a fast growing engineering organization, ownership of services changes fairly frequently. Many cycles get burned in chat with questions like "Who owns service x now?

Whilst it's easy to see how a tool like this saves a few seconds per day for the asker and askee, and saves on some mental context switches, the time saved is unlikely to add up to the cost of development and maintenance.

= 5 minutes per day
x 260 work days 
= 1300 mins 
/ 60 mins 
= 20 person hours per year

So a 20 hour investment in that tool would pay itself back in a year valuing everyone's time the same. While we've made great strides in improving the efficiency of building tools at Cloudflare, 20 hours is a stretch for an end-to-end build, deploy and operation of a new tool.

Enter Cloudflare Workers + Workers KV

The more I use Serverless and Workers, the more I'm struck with the benefits of:

1. Reduced operational overhead

When I upload a Worker, it's automatically distributed to 175+ data Continue reading

We want to host your technical meetup at Cloudflare London

Cloudflare recently moved to County Hall, the building just behind the London Eye. We have a very large event space which we would love to open up to the developer community. If you organize a technical meetup, we'd love to host you. If you attend technical meetups, please share this post with the meetup organizers.

We want to host your technical meetup at Cloudflare London
We're on the upper floor of County Hall

About the space

Our event space is large enough to hold up to 280 attendees, but can also be used for a small group as well. There is a large entry way for people coming into our 6th floor lobby where check-in may be managed. Once inside the event space, you will see a large, open kitchen area which can be used to set up event food and beverages. Beyond that is Cloudflare's all-hands space, which may be used for your events.

We have several gender-neutral toilets for your guests' use as well.

Lobby

You may welcome your guests here. The event space is just to the left of this spot.

Automation Solution: Create Switch Stack Reports

Have you ever wondered how many free ports you have on your stackable campus switches? I’m sure there must be a wonderful network management tool that creates that reports with a click of a button… but what if the tool your PHB purchased based on awesome PowerPoint and glitzy demo can’t do that?

Nadeem Lughmani decided to solve this challenge as a hands-on assignment in the Building Network Automation Solutions online course and created an Ansible playbook and a Python plugin that counts the total number of ports and number of free ports for each switch stack specified in the device inventory.

Wonder what else course attendees created in the past? Here’s a small sample.

BrandPost: Is 802.11ax the End of Dual 5 -GHz Radio APs?

There are a lot of things that remain to be seen about how 802.11ax will affect wireless network design. An interesting side effect of the addition of OFDMA to the standard may be an end to the dual 5 GHz access point (AP). In a typical campus wireless network, we don’t need as many 2.4 GHz radios as 5 GHz radios. Rather, we are more limited in the number we can use because the 2.4 GHz spectrum has fewer channels and a larger coverage area. This issue is even more pronounced in high-density wireless deployments.Rather than just disable the 2.4 GHz radio, some APs allow you to switch the unneeded 2.4 GHz radio to a 5 GHz radio in software. This can be useful because there are a lot more available 5 GHz channels, so rather than having a bunch of APs with only one radio you can add 5 GHz capacity to the network with the same number of APs.To read this article in full, please click here
