3 Tools for Getting VMs From Your Datacenter to the AWS Cloud

Here's a simple scenario: you have some Virtual Machines (VMs) in your on-premises environment, likely in VMware vSphere or Microsoft Hyper-V. You want to either fully migrate some or all of those VMs to the AWS Cloud or you want to copy a gold image to the AWS Cloud so you can launch compute instances from that image. Simple enough.

Now, how do you do it?

Can you just export an OVA of the VM, copy it up, and then boot it? Can you somehow import the VMDK files that hold the VM's virtual drive contents? Regardless the eventual method, how do you do it at scale for dozens or hundreds of VMs? And lastly, how do you orchestrate the process so that VMs belonging to an application stack are brought over together, as a unit?

The Week in Internet News: Community Broadband Offers Fastest Speeds in U.S.

Super fast: ISPs run by local communities or run through a partnership with a local community offer some of the fastest broadband in the U.S., a story at Vice.com says. Six of the 10 fastest ISPs in the country are either operated by local communities or are partnerships between the public and private sectors, according to a PCMag review.

Conflicting laws: Australia’s recently-passed encryption law, which mandates law enforcement access to encrypted communications, may conflict with the EU’s GDPR and the U.S. CLOUD Act, according to a story at ZDNet. Australian law enforcement agencies may have trouble requiring U.S. and EU companies to decrypt data, the Law Council of Australia has said.

Tweeting is back: The government of Chad has restored access to social media after a 16-month shutdown, QZ.com reports. That’s a lot of missed likes. The government had restricted access to electronic communications for “security reasons” and in “a context of terrorist threats.”

It steals your face: Mobile phone apps that allow you to edit pictures of your face may introduce security vulnerabilities, Forbes notes. One app may upload faces to a database without users’ permission, and another app Continue reading

AT&T partners with IBM and Microsoft, focuses on network capabilities

Earlier this year, AT&T finalized a deal to divest itself of its 31 data centers for $1.1 billion. Now that it has dumped its data center business, the company partnering with two of the largest providers of them: Microsoft and IBM.IBM and AT&T this week announced a multi-year strategic alliance where AT&T’s network and IBM Cloud will link up to provide software-defined network (SDN) services, including giving IBM Cloud access to AT&T’s 5G network. In return, IBM will make AT&T its primary provider of 5G, edge computing, and internet of things (IoT) services and help manage AT&T’s entire infrastructure footprint, including third-party cloud services, using Red Hat’s open-source tools to manage the network. This isn’t really new, as AT&T was using Red Hat Enterprise Linux (RHEL) for some time.To read this article in full, please click here

Sudden Explosion of Data Centers in India

 

Something very interesting is happening in the Indian telecom space these days.

The Indian government is considering a new data localisation law that would require all data around Indian citizens to be stored locally, i.e., within Indian borders. It starts with the fintech companies first, and would then bring in the social media and other IOT companies storing data in its ambit. The Reserve Bank of India (RBI) has cheerfully given a deadline to all fintech companies to ensure that the entire data operated by them, is stored in data centers only in India. Ouch.

RBI so far has refused to accept the representations made by the fintech companies to relax the norms. It’s ruled out the option of data mirroring while addressing the arguments of technological hurdles raised by the fintech companies. It’s instead suggested that companies opt for cloud services or private clouds in order to ensure data localization.

So, what’s data localisation? Data localisation is the process localising the citizen’s data to one’s home country for its processing, storage and collection before it goes through the process of being transferred to an international level. It’s done to ensure the country’s data protection and privacy Continue reading

A Makefile for your Go project (2019)

My most loathed feature of Go was the mandatory use of GOPATH: I do not want to put my own code next to its dependencies. I was not alone and people devised tools or crafted their own Makefile to avoid organizing their code around GOPATH.

Hopefully, since Go 1.11, it is possible to use Go’s modules to manage dependencies without relying on GOPATH. First, you need to convert your project to a module:1

$ go mod init hellogopher
go: creating new go.mod: module hellogopher
$ cat go.mod
module hellogopher

Then, you can invoke the usual commands, like go build or go test. The go command resolves imports by using versions listed in go.mod. When it runs into an import of a package not present in go.mod, it automatically looks up the module containing that package using the latest version and adds it.

$ go test ./...
go: finding github.com/spf13/cobra v0.0.5
go: downloading github.com/spf13/cobra v0.0.5
?       hellogopher     [no test files]
?       hellogopher/cmd [no test files]
ok      hellogopher/hello       0.001s
$ cat go.mod
module hellogopher

require github.com/spf13/cobra v0.0.5

If you want a specific version, you can Continue reading

Sustainable Python scripts

Python is a great language to write a standalone script. Getting to the result can be a matter of a dozen to a few hundred lines of code and, moments later, you can forget about it and focus on your next task.

Six months later, a co-worker asks you why the script fails and you don’t have a clue: no documentation, hard-coded parameters, nothing logged during the execution and no sensible tests to figure out what may go wrong.

Turning a “quick-and-dirty” Python script into a sustainable version, which will be easy to use, understand and support by your co-workers and your future self, only takes some moderate effort. As an illustration, let’s start from the following script solving the classic Fizz-Buzz test:

import sys
for n in range(int(sys.argv[1]), int(sys.argv[2])):
    if n % 3 == 0 and n % 5 == 0:
        print("fizzbuzz")
    elif n % 3 == 0:
        print("fizz")
    elif n % 5 == 0:
        print("buzz")
    else:
        print(n)

Documentation​

I find useful to write documentation before coding: Continue reading

Rant: Some Internet Service Providers Should Really Know Better…

I was listening to a nice podcast with Nick Buraglio discussing the recent BGP hijack SNAFU impacting Cloudflare (and their reaction) and while I usually totally agree with Nick, I think that he tried to be way too nice when saying (paraphrasing) “I think Cloudflare was a bit harsh - I would prefer a more community-oriented approach along the lines of how could we help you do your job better”

RightsCon 2019: Human Rights in the Digital Age

Since its creation in 2011, RightsCon has gathered people from different sectors to discuss human rights in the digital age. It started as an event with a few hundred experts, but has become a major conference, with nearly 3000 participants in 2019. The 2019 program consisted of 17 tracks focusing on major issues, which totalized more than 450 sessions held in a period of four days.

As the conference started to attract a wider group of people, it adopted a series of measures to increase its diversity. The recent host countries, including Tunisia and Costa Rica, reflect the worldwide nature of the event, which now gathers individuals from all over the globe.

RightsCon has also gathered a considerable number of young people. They’ve had the opportunity to connect not only through regular conference activities, but during a summit on Day Zero. The summit aimed to engage youth and also brief them on the discussions taking place during the  rest of RightsCon.

The sessions at RightsCon were designed with different formats, which was reflected in the physical structure of the meeting rooms. They were organized not just in an audience format, but also roundtables, allowing for people to feel equal footing Continue reading

10x Engineers – Don’t Believe The Hype

The idea of a 10x engineer is just too good to be true. In this Short Take I take a look at the recent controversy and share my thoughts about the twitter thread that sparked it all. Here’s a hint, there’s no such thing as a 10x engineer but there are some things to be learned from what the author had to say.
