Network automation helps more than just network admins

Systems administrators are the heart of any IT team. Since IT is arguably what keeps most modern organizations operating, then in some ways sysadmins are the heart of modern organizations. Of course network automation can make the lives of network engineers easier, but it can also benefit enterprises as a whole. Yet here’s an interesting quandary: does network automation even benefit systems administrators?

Sysadmins shepherd hardware, virtualization platforms, Operating System Environments (OSEs), and more.  They must master multiple disciplines within IT, and are under the constant pressure to learn even more. The life of a systems administrator is one of trying to carefully balance the solving of immediate problems while investing with their future via automation to prevent these problems from recurring, additionally with lifelong learning.

As a profession, systems administration has been cyclical. In one part of the cycle the generalist sysadmin is championed. In the next, specialization is all the rage.  The past decade has seen the generalist brought once more to the fore, as specialties such as “storage administrator” are automated away by clever software.

However, throughout the decades the physical networks have largely remained the jurisdiction of dedicated network administrators.  If the networks belong to Continue reading

Devops with Kubernetes

I did the following presentation “Devops with Kubernetes” in Kubernetes Sri Lanka inaugural meetup earlier this week. Kubernetes is one of the most popular open source projects in the IT industry currently. Kubernetes abstractions, design patterns, integrations and extensions make it very elegant for Devops. The slides delve little deep on these topics. How Kubernetes … Continue reading Devops with Kubernetes

Docker at Microsoft Ignite 2018

 

Docker will be at Microsoft Ignite in Orlando, FL the week of Sept 24th to showcase the latest release of Docker Enterprise. Specifically, we will be sharing insights for how to move your legacy Windows applications from Windows Server 2003/2008 to Windows Server 2016 and Azure.

Visit Docker in Booth #644 to learn more about how we’re helping IT organizations learn about Docker Enterprise tools that help you to id and containerize Windows legacy applications. We’ll have technical experts there to answer your questions.

Make sure to check out these sessions featuring Docker:

  • From Ops to DevOps with Windows Containers and Windows Server 2019. Specifically we are highlighting Lindsay, a joint Docker Microsoft customer that has migrated Windows legacy apps with Docker Enterprise to Azure. You can get more details about the session here.
  • Thursday 9/27 @ 2pm: HPE Theatre in the HPE booth #2125. The session will focus on how Docker Enterprise is  helping customers migrate their legacy apps and run them in a hybrid environment.

Introducing the Cloudflare Onion Service

Introducing the Cloudflare Onion Service
  • When: a cold San Francisco summer afternoon
  • Where: Room 305, Cloudflare
  • Who: 2 from Cloudflare + 9 from the Tor Project
Introducing the Cloudflare Onion Service

What could go wrong?

Bit of Background

Two years ago this week Cloudflare introduced Opportunistic Encryption, a feature that provided additional security and performance benefits to websites that had not yet moved to HTTPS. Indeed, back in the old days some websites only used HTTP --- weird, right? “Opportunistic” here meant that the server advertised support for HTTP/2 via an HTTP Alternative Service header in the hopes that any browser that recognized the protocol could take advantage of those benefits in subsequent requests to that domain.

Around the same time, CEO Matthew Prince wrote about the importance and challenges of privacy on the Internet and tasked us to find a solution that provides convenience, security, and anonymity.

From neutralizing fingerprinting vectors and everyday browser trackers that Privacy Badger feeds on, all the way to mitigating correlation attacks that only big actors are capable of, guaranteeing privacy is a complicated challenge. Fortunately, the Tor Project addresses this extensive adversary model in Tor Browser.

However, the Internet is full of bad actors, and distinguishing Continue reading

Using CSR1000V in AWS Instead of Automation or Orchestration System

As anyone starting their journey into AWS quickly discovers, cloud is different (or as I wrote in the description of my AWS workshop you feel like Alice in Wonderland). One of the gotchas: when you link multiple routing domains (Virtual Private Clouds – the other VPC) you have to create static routing table entries on both ends. Even worse, there’s no transit VPC – you have to build a full mesh of relationships.

The correct solution to this challenge is automation:

First Subsea Cable Across South Atlantic Activated

Yesterday marked the first time in recent Internet history that a new submarine cable carried live traffic across the South Atlantic, directly connecting South America to Sub-Saharan Africa.  The South Atlantic Cable System (SACS) built by Angola Cables achieved this feat around midday on 18 September 2018.

Our Internet monitoring tools noticed a change in latency between our measurement servers in various Brazilian cities and Luanda, Angola, decreasing from over 300ms to close to 100ms.  Below these are measurements to Angolan telecoms TVCABO (AS36907) and Movicel (AS37081) as the SACS cable came online yesterday.

A race to be first

In the past decade there have been multiple submarine cable proposals to full this gap in international connectivity, such as South Atlantic Express (SAEx) and South Atlantic Inter Link (SAIL) cables.

In recent weeks, the SAIL cable, financed and built by China, announced that they had completed construction of their cable and it was the first cable connecting Brazil to Africa (Cameroon). However, since we haven’t seen any changes in international connectivity for Cameroon, we don’t believe this cable is carrying any traffic yet.

What’s the significance?

In addition to directly connecting Brazil to Portuguese-speaking Angola, the cable offers Continue reading

ICANN sets plan to reinforce internet DNS security

In a few months, the internet will be a more secure place. That’s because the Internet Corporation for Assigned Names and Numbers (ICANN) has voted to go ahead with the first-ever changing of the cryptographic key that helps protect the internet’s address book – the Domain Name System (DNS). [ Now see: The hidden cause of slow internet and how to fix it. ] The ICANN Board at its meeting in Belgium this week, decided to proceed with its plans to change or "roll" the key for the DNS root on Oct. 11, 2018. It will mark the first time the key has been changed since it was first put in place in 2010.To read this article in full, please click here
