Public cloud providers such as AWS, Google, and Microsoft Azure publish shared responsibility models that push security of the data, platform, applications, operatingsystem, network and firewall configuration, and server-side encryption, to the customer. Opensource applications running in the cloud need to be copyrighted.
Companies that have embraced the cloud need to understand the Shared Responsibility Model: a security and compliance framework that explains what shared infrastructure and systems the cloud provider is responsible for maintaining and how a customer is responsible for operatingsystems, data, and applications utilizing the cloud.

Where Is Mirantis Finding Talent to Build the Open-Source OpenStack Cloud? Can OpenStack scale?
Most notably, it was the release of Doom ’s source code in the late ‘90s that has allowed the classic shooter to be hacked into dozens of unusual devices from ATMs to digital cameras. This open-sourcing tradition continued up until the Doom 3 engine, whose source code was released in 2011.
SkyScalpel is an opensource tool that “obfuscates, deobfuscates, and detects obfuscated JSON documents” It makes perfect sense now, but before reading about SkyScalpel I hadn’t considered the idea of obfuscating JSON documents in policy statements (such as an AWS IAM policy) to hide the policy’s true intent.
Even Facebook, which has opensourced much of its designs for its data center hardware but remains vague about its server count, saying only that it operates “hundreds of thousands” of machines. Microsoft’s ‘Cloud OperatingSystem’ 218,000 Servers in Microsoft Data Centers? Networking.

What You’ll Need.
It begins with a unified software stack integrated at the operatingsystem level rather than bolted together with APIs. The VP80ES is a powerful data storage solution that represents a one-stop shop for small and medium-sized businesses, with its 8TB drive costing a fraction of similarly capable models.

I just saw the news that Citrix has acquired Sanbolic , a storage virtualization company that I’ve written about before. KVM seems to be the opensource hypervisor of choice while VMware’s vSphere continues to dominate (for now) the commercial market—leaving XenServer with leftovers. TechCrunch also has a quick write-up as well.)

OperatingSystems/Applications. I found this article on imperative vs. declarative system configuration is quite helpful in understanding Puppet’s declarative model. QEMU, on the other hand, is needed to emulate everything else that a VM needs: networking, storage, USB, keyboard, mouse, etc. Apparently, “Mt.
Well, let’s see…stuff on Envoy, network automation, network designs, M1 chips (and potential opensource variants!), Are opensource M1-style chips a possibility? OperatingSystems/Applications. Welcome to Technology Short Take #145! What will you find in this Tech Short Take? Thank you, Ben!

Erik Smith, notably known for his outstanding posts on storage and FCoE, takes a stab at describing some of the differences between SDN and network virtualization in this post. I found this series of posts to be helpful when I was working on configuring LACP with Open vSwitch (I hope to have a blog post on that up soon).
I saw this blog post about Curiefense , an opensource Envoy extension to add WAF (web application firewall) functionality to Envoy. I really enjoy these AWS opensource news and updates posts. It’s a good starting point for thinking about operating your own active-active architecture. Servers/Hardware.

For all your other desktop software needs, there’s usually a free, open-source program that can do just as good a job. This is an image of the Mint operatingsystem which you can use to run or install the operatingsystem. You should also set it to update your system to the latest version of Mint.

I find it enormously helpful to stay connected to various opensource-related IRC channels, but staying logged while on the move is, for all intents and purposes, impossible. Visit the site for more information on virtualization, servers, storage, and other enterprise technologies.
As opposed to just encrypting data at the transport level (although Acra does that between components of its architecture) or just encrypting data at the storage level (using an encrypted file system or similar), Acra targets encrypting data at the table/row/column level within a database. Acra is opensource and available via GitHub.

This time around, the content is a bit heavier on cloud management and applications/operatingsystems, but still lots of good content all the way around (I hope, anyway). Jason Edelman has posted a self-compiled list of networking projects that are opensource ; this is a useful list, so thanks for compiling it Jason!
Engin Diri’s article on continuous cluster audit scanning with Trivy is a “two-for-one” article: you get to see some Pulumi YAML to create a Kubernetes cluster on Civo, and you get to see writing policies for the Trivy Operator. Ricardo Sueiras captured some great links on opensource at AWS in this newsletter.
