Rook is currently in alpha state and has focused initially on orchestrating Ceph on-top of Kubernetes. Ceph is a distributed storage system that provides file, block and object storage and is deployed in large scale production clusters." fastest, privacy-first DNS by CloudFlare

CloudFlare is most often associated with CDN and DDoS protection services it provides. 
Now they provide public DNS also, that could be configured in computers and mobile devices 
instead of default DNS provided by internet providers. 

Announcing the fastest, privacy-first consumer DNS service

"DNS's Privacy Problem
...What many Internet users don't realize is that even if you're visiting a website that is encrypted — has the little green lock in your browser — that doesn't keep your DNS resolver from knowing the identity of all the sites you visit. That means, by default, your ISP, every wifi network you've connected to, and your mobile network provider have a list of every site you've visited while using them."

CloudFlare's outperformed any of the other consumer DNS services available (including Google's 

14.8ms :
20.6ms : Cisco OpenDNS
34.7ms: Google Public DNS (

GDPR & Clouds

GDPR rules apply to sites used by residents of  EU,  essentially the whole world.

The InfoQ eMag: Perspectives on GDPR

"...EU’s General Data Protection Regulation (GDPR) not only comes into effect, but actually produces a body of precedents on what exactly constitutes a violation subject to a fine (which, remember, can be as high as €20 million or 4% of annual global turnover, whichever is greater)..."

"The European Union’s General Data Protection Regulation (GDPR) protects European Union data subjects' fundamental right to privacy and the protection of personal data. It introduces robust requirements that will raise and harmonize standards for data protection, security, and compliance."

"On 25 May 2018, the most significant piece of European data protection legislation to be introduced in 20 years will come into force. The EU General Data Protection Regulation (GDPR)..."

IoT edge: Microsoft Azure Sphere: micro-controller + Linux + Cloud

Introducing Microsoft Azure Sphere: Secure and power the intelligent edge | Blog | Microsoft Azure
  • "Azure Sphere certified microcontrollers (MCUs):
  • Azure Sphere OS: This OS is purpose-built to offer unequalled security and agility. Unlike the RTOSes common to MCUs today, our defense-in-depth IoT OS offers multiple layers of security. It combines security innovations pioneered in Windows, a security monitor, and a custom Linux kernel to create a highly-secured software environment and a trustworthy platform for new IoT experiences.
  • Azure Sphere Security Service: (Cloud)"

Linux Is Microsoft's OS of Choice for Internet of Things Devices | Digital Trends

"Microsoft introduced Azure Sphere during the RSA security conference in San Francisco. It’s essentially a platform connecting microcontroller units (MCU) within Internet of Thing devices to the cloud. What’s notable about this announcement is that the operating system installed on the MCUs aren’t based on Windows 10 as you would expect, but rather a custom build of the open-source Linux operating system. That’s a first for Microsoft."

"It’s a “crossover” chip that combines the benefits of ARM-based Cortex-A and Cortex-M processor cores."

"...there’s a key reason why Microsoft likely went with Linux instead of its in-house baked Windows 10: Open source. According to Microsoft, Azure Sphere is “open to additional software innovation” by the open source community. It’s also open to work with any cloud, not just Microsoft’s Azure-branded platform. Even more, the chip design can be used by any manufacturer absolutely free."

AWS S3 Select: cloud storage with SQL filtering

S3 Select and Glacier Select – Retrieving Subsets of Objects | AWS News Blog

"With S3... individual objects can be as large as 5 terabytes. Data in object storage have traditionally been accessed as a whole entities, meaning when you ask for a 5 gigabyte object you get all 5 gigabytes. It’s the nature of object storage. Today we’re challenging that paradigm by announcing two new capabilities for S3 and Glacier that allow you to use simple SQL expressions to pull out only the bytes you need from those objects. This fundamentally enhances virtually every application that accesses objects in S3 or Glacier."
"As an (Python) example, let’s imagine you’re a developer at a large retailer and you need to analyze the weekly sales data from a single store, but the data for all 200 stores is saved in a new GZIP-ed CSV every day. Without S3 Select, you would need to download, decompress and process the entire CSV to get the data you needed. With S3 Select, you can use a simple SQL expression to return only the data from the store you’re interested in, instead of retrieving the entire object."

import boto3 s3 = boto3.client('s3') r = s3.select_object_content( Bucket='jbarr-us-west-2', Key='sample-data/airportCodes.csv', ExpressionType='SQL', Expression="select * from s3object s where s.\"Country (Name)\" like '%United States%'", InputSerialization = {'CSV': {"FileHeaderInfo": "Use"}}, OutputSerialization = {'CSV': {}}, )

Azure IoT Edge vs AWS Greengrass

"Azure IoT Edge is designed to run on multiple platforms (Windows and many versions of Linux), and hardware architectures (x64 and ARM). To deploy workloads, Azure IoT Edge can use Linux Containers for Docker or Windows Containers for Docker, with an open design to incorporate number of popular container management systems."

Azure IoT Hub Documentation - Tutorials, API Reference | Microsoft Docs

Azure IoT Edge - Tutorials, API Reference | Microsoft Docs

"Azure IoT Edge is an Internet of Things (IoT) service that builds on top of IoT Hub. This service is meant for customers who want to analyze data on devices, a.k.a. "at the edge", instead of in the cloud. By moving parts of your workload to the edge, your devices can spend less time sending messages to the cloud and react more quickly to changes in status."

"Azure IoT Edge lets you deploy and manage business logic on the edge in the form of modules. Azure IoT Edge modules are the smallest unit of computation managed by IoT Edge, and can contain Azure services (such as Azure Stream Analytics) or your own solution-specific code. To understand how modules are developed, deployed, and maintained, it helps to think of four conceptual pieces that make up a module:
  • A module image is a package containing the software that defines a module.
  • A module instance is the specific unit of computation running the module image on an IoT Edge device. The module instance is started by the IoT Edge runtime.
  • A module identity is a piece of information (including security credentials) stored in IoT Hub, that is associated to each module instance.
  • A module twin is a JSON document stored in IoT Hub, that contains state information for a module instance, including metadata, configurations, and conditions."
Understand the Azure IoT Edge runtime | Microsoft Docs
  • "Edge Hub facilitates module to module communication. Using Edge Hub as a message broker keeps modules independent from each other.
  • The IoT Edge agent is the other module that makes up the Azure IoT Edge runtime. It is responsible for instantiating modules, ensuring that they continue to run, and reporting the status of the modules back to IoT Hub."
IoT Edge runtime communicates insights and module health to IoT Hub

"Local compute, messaging, data caching, sync, and ML inference capabilities for connected devices.
