BrandPost: 3 Essentials for Achieving Resiliency at the Edge

“The IT industry has done a good job of making robust data centers that are highly manageable, highly secure, with redundant systems,” says Kevin Brown, SVP Innovation and CTO for Schneider Electric’s Secure Power Division. However, he continues, companies then connect these data centers to messy edge closets and server rooms, which over time have become “micro mission-critical data centers” in their own right — making system availability vital. If not designed and managed correctly, the situation can be disastrous if users cannot connect to business-critical applications.  To read this article in full, please click here

CCAOI-ISOC Delhi Webinar on the Draft National e-Commerce Policy

The Indian government’s Department for Promotion of Industry and Internal Trade has released a draft of the National e-Commerce Policy for public comments by 29 March 2019. The CCAOI, with support from the Internet Society India Delhi Chapter, organized a webinar to discuss the draft policy on 18 March. The objective of the discussion was to inform various stakeholders of the provisions of the draft policy and highlight issues of concern. Watch the recording here.

The session was moderated by Subhashish Panigrahi and myself. It was attended by over 45 participants from different stakeholder communities across the country. The speakers that participated in the session were Devika Aggarwal from NASSCOM, Ankit Anand from Reliance Jio, Nikhil Pahwa from MediaNama, Parminder Singh from IT for Change, and Dr. Mahesh Uppal from ComFirst (India) Private Limited.

To kick off the webinar, Smitha Krishna Prasad of the Centre for Communication Governance at the National Law University presented an overview of the draft policy, following which the speakers shared their perspectives on the draft policy. Towards the end of the webinar, speakers answered questions from the participants in a lively and interactive Q&A session.

Some of the key issues discussed were on the Continue reading

How Istio, NSX Service Mesh and NSX Data Center Fit Together

This is the year of the service mesh. Service mesh solutions like Istio are popping up everywhere faster than you can say Kubernetes. Yet, with the exponential growth in interest also comes confusion. These are a few of the questions I hear out there:

  1. Where is the overlap between NSX service mesh (NSX-SM) with NSX-Datacenter (NSX-DC)?
  2. Is there synergy between the NSX-DC and Istio?
  3. Can service mesh be considered networking at all?

These are all excellent and valid questions. I will try to answer them at the end of the post, but to get there let’s first understand what each solution is trying to achieve and place both on the OSI layer to bring more clarity to this topic.

*Note – I focused this post on NSX-DC and Istio, to prevent confusion, Istio is an open source service mesh project, while NSX-SM is a VMware service delivering enterprise-grade service mesh, while it is built on top of Istio, it brings extensive capabilities beyond those that are offered by the Istio Open Source project.

 

Before we start, in a nutshell, what is Istio?

Istio (https://istio.io/) Is an Open Source service mesh project led by Google that addresses Continue reading

When Wi-Fi is mission-critical, a mixed-channel architecture is the best option

I’ve worked with a number of companies that have implemented digital projects only to see them fail. The ideation was correct, the implementation was sound, and the market opportunity was there. The weak link? The Wi-Fi network.For example, a large hospital wanted to improve clinician response times to patient alarms by having telemetry information sent to mobile devices. Without the system, the only way a nurse would know about a patient alarm is from an audible alert. And with all the background noise, it’s often tough to discern where noises are coming from. The problem was the Wi-Fi network in the hospital had not been upgraded in years and caused messages to be significantly delayed in their delivery, often taking four to five minutes to deliver. The long delivery times caused a lack of confidence in the system, so many clinicians stopped using it and went back to manual alerting. As a result, the project was considered a failure.To read this article in full, please click here

IDG Contributor Network: Zero-trust: microsegmentation networking

The transformation to the digital age has introduced significant changes to the cloud and data center environments. This has compelled the organizations to innovate more quickly than ever before. This, however, brings with it both – the advantages and disadvantages.The network and security need to keep up with this rapid pace of change. If you cannot match with the speed of the digital age, then ultimately bad actors will become a hazard. Therefore, the organizations must move to a zero-trust environment: default deny, with least privilege access. In today’s evolving digital world this is the primary key to success.To read this article in full, please click here

Cognitive WiFi is Here

cognitive-campus-blog-ju-19

Last August, Arista made its first acquisition, Mojo Networks, to transform the future of WiFi and campus networks. Just as Arista disrupted the datacenter with important architectural and technology-based innovations, I believe this is a similar pioneering step for the campus. Over the past two decades, the industry has deployed a WiFi controller-based architecture. This stagnant “WLC” approach for wireless connectivity has not evolved to address costly operational dilemmas such as:

Automatic Clean-and-Updated Firewall Ruleset

This is a guest blog post by Andrea Dainese, senior network and security architect, and author of UNetLab (now EVE-NG) and  Route Reflector Labs. These days you’ll find him busy automating Cisco ACI deployments.

Following the Ivan’s post about Firewall Ruleset Automation, I decided to take a step forward: can we always have up-to-date and clean firewall policies without stale rules?

The problem

We usually configure and manage firewalls using a process like this:
