Introducing NSX-T 2.1 with Pivotal Integration
Application architectures are evolving. That shouldn’t be news to anyone. Today, emerging app architectures that leverage container-based workloads and microservices are becoming mainstream, moving from science projects in development labs to enterprise production deployments at scale. The benefits are clear. Developers and the application lifecycle, become faster, more productive, more agile, and more responsive to the needs of the business.
Today we’re announcing NSX-T 2.1, which will enable advanced networking and security across these emerging app architectures, just as it does for traditional 3-tier apps. More specifically, NSX-T 2.1 will serve as the networking and security platform for the recently announced VMware Pivotal Container Service (PKS), a Kubernetes solution jointly developed by VMware and Pivotal in collaboration with Google. NSX-T 2.1 will also introduce integration with the latest 2.0 release of Pivotal Cloud Foundry (PCF), serving as the networking and security engine behind PCF. In these environments, NSX-T will provide Layer 3 container networking and advanced networking services such as load balancing, micro-segmentation, and more.
For development teams, these integrations mean that they will be able operate quickly and consume infrastructure as code. Meanwhile, their workflows will remain the same — fast and efficient — because NSX-T will integrate tightly with these application platforms, connecting directly into the Continue reading

Introducing the Cloudflare Warp Ingress Controller for Kubernetes
It’s ironic that the one thing most programmers would really rather not have to spend time dealing with is... a computer. When you write code it’s written in your head, transferred to a screen with your fingers and then it has to be run. On. A. Computer. Ugh.
Of course, code has to be run and typed on a computer so programmers spend hours configuring and optimizing shells, window managers, editors, build systems, IDEs, compilation times and more so they can minimize the friction all those things introduce. Optimizing your editor’s macros, fonts or colors is a battle to find the most efficient path to go from idea to running code.

Once the developer is master of their own universe they can write code at the speed of their mind. But when it comes to putting their code into production (which necessarily requires running their programs on machines that they don’t control) things inevitably go wrong. Production machines are never the same as developer machines.
If you’re not a developer, here’s an analogy. Imagine carefully writing an essay on a subject dear to your heart and then publishing it only to be Continue reading
Creating a mixed-mode Virtual Chassis Fabric (VCF)
In order to mix EX switches and QFX switches in the same VCF, you need to enable mixed-mode. This requires all members of the VCF to reboot unfortunately:
{master:1}
imtech@sw0-24c> request virtual-chassis mode fabric mixed
fpc0:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)
fpc2:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)
fpc3:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)
fpc1:
--------------------------------------------------------------------------
WARNING, Virtual Chassis Fabric mode enabled without a valid software license.
Please contact Juniper Networks to obtain a valid Virtual Chassis Fabric License.
Mode set to 'Fabric with mixed devices'. (Reboot required)

Once you’ve cabled up your QSFP ports between the EX4300 you are adding and the QFX spines, you need to do the following:
Enable the VCF port on the QFX spine:

Communities Can Own Their Internet Destiny
Imagine you wanted to have an Internet connection and someone decided that you had to wait an undefined amount of time (maybe a year, maybe 10 years) to get access. Would you find it fair? I wouldn’t!
Unfortunately, this is the situation that millions of people in remote communities around the world have to accept. They will have Internet access only when operators decide to give them access which can be in a decade or more. These people won’t enjoy all the benefits we are enjoying today for a long time. And as more and more services go online – and exclusively online – they will not get the services they used to have since the services have moved to a new place where they are not allowed to be.
This is happening because operators can’t expand everywhere at the same time; they have to choose where they go this year, then next year, etc. There are some places where they will never go because those places are not going to bring them money. Among those regions that operators will never choose to go, we find, sadly, are the poorest rural areas that desperately need the economic and development opportunities Continue reading
