cloud: Data Transfer Project by Google, Facebook, Microsoft, Twitter

Google, Facebook, Microsoft, and Twitter partner for ambitious new data project - The Verge

"Google, Facebook, Microsoft, and Twitter joined to announce a new standards initiative called the Data Transfer Project, designed as a new way to move data between platforms. In a blog post, Google described the project as letting users “transfer data directly from one service to another, without needing to download and re-upload it.”

The current version of the system supports data transfer for photos, mail, contacts, calendars, and tasks, drawing from publicly available APIs from Google, Microsoft, Twitter, Flickr, Instagram, Remember the Milk, and SmugMug.
...
The existing code for the project is available open-source on GitHub, along with a white paper describing its scope. Much of the codebase consists of “adapters” that can translate proprietary APIs into an interoperable transfer, making Instagram data workable for Flickr and vice versa."

Azure Service (Fabric) Mesh

A "new" buzzword for cloud: Service Mesh

Azure Service Fabric Mesh preview


Service mesh | Technology Radar | ThoughtWorks

How to choose and deploy a service mesh - O'Reilly Media


https://pages.buoyant.io/Oreilly-Service-Mesh-Book.html

"In cloud native architectures, your network becomes the fundamental determining factor for how your applications behave at runtime. The shift to microservices solves many problems, but it also introduces a new set of reliability, performance, and security challenges inherent to managing distributed systems. The service mesh helps you wrangle that complexity by providing a uniform way to manage, monitor, and control your production applications."

ML with IoT Edge

Machine Learning - Machine Learning with IoT Devices on the Edge @ MSDN Magazine

example described: "smart traffic intersection. ... four video cameras connected to an Internet of things (IoT) device with a small CPU, similar to a Raspberry Pi. The cameras send video frames to the IoT device, where they’re analyzed using a machine learning (ML) image-recognition model and control instructions are then sent to the traffic signals. One of the small IoT devices is connected to Azure Cloud Services, where information is logged and analyzed offline.
...
The demo programs described in this article (a Python program that uses the CNTK library to create an ML model, a C program that simulates IoT code and a Python program that uses an ELL model"


The ELL Workflow Process, High-Level and Granular

The controller device described in article could be Azure Sphere
Microsoft CNTK has some advantages, but is a bit less "popular" than Google's TensorFlow library.
And for Microsoft developers, having C# (Core) option may be preferred to Python.
Anyway, an interesting article.

Google Flutter: Dart + Skia = mobile future!


Two excellent, very informative technical podcast interviews!

technical background, from users perspective:
Flutter in Practice with Randal Schwartz - Software Engineering Daily

technical background, from creators and project lead perspective:
Flutter with Eric Seidel - Software Engineering Daily

Flutter is created by extracting and re-purposing "essence" from Chrome engine, with intent to make universal mobile app platform, that can run natively on both Android and iOS.

How is this done? By using Chrome's high performance graphical rendering engine Skia as well as its text renderer.  Dart programming language is used for complete end-to-end platform, no "bridges" to

OS widgets renderer, like it done by React Native or Xamarin for example. The result is much better performance, simplicity, and less HW requirements: it could also run on IoT devices, for example.
So Flutter is using same code for running on all platforms, no need for different view layers.

DartDart language is also very important. Created by same person, Danish computer scientist Lars Bak. He created Java's high performance HotSpot JIT compiler, that made Java really usable. Then created JavaScript V8 engine that made  web apps possible by improving performance 1000+ times. Dart is essentially what JavaScript could have been if it could break backward compatibility. It is type safe language, that can run with its own high-performance JIT VM, or it can cross compile to JavaScript to run in any web browser, or it can compile directly to native code for optimal mobile applications.

Google is apparently using Dart with Angular for its most critical business applications (for advertising), instead of previously used  Java Closure compiler that generated JavaScript from simplified Java code.

In parallel with Angular Dart Google also develops Angular TypeScript , that is very popular outside of Google. TypeScript is created by another very prominent Danish computer scientist,
Anders Hejlsberg. the "father" to Turbo Pascal, Delphi and Microsoft C#.

Flutter has potential to be a basis of Google Fuchsia, that could be a replacement of current Android platform.

So Flutter & Dart have potential to be a "big deal" in technology future.

GitHub MySQL cluster or clusters

A good use-case for upgrade to Azure Cosmos DB, when acquisition is completed?

Github Engineering Adopts New Architecture for MySQL High Availability @ InfoQ

"Github's infrastructure is spread out across multiple datacenters, consisting of around 15 clusters, close to 150 production servers and 15 TB of MySQL tables. Each MySQL cluster has a single master, which responds to write requests, and multiple replicas which serve read requests."

mobile AI: Google ML Kit


ML Kit for Firebase | Machine learning for mobile developers  |  Firebase

"ML Kit lets you bring powerful machine learning features to your app whether it's for Android or iOS, and whether you're an experienced machine learning developer or you're just getting started.

ML Kit gives you both on-device and Cloud APIs, all in a common and simple interface, allowing you to choose the ones that fit your requirements best. The on-device APIs process data quickly and will work even when there’s no network connection, while the cloud-based APIs leverage the power of Google Cloud Platform's machine learning technology to give a higher level of accuracy."

Service Mesh: Linkerd

Which Service Mesh Should I Use? - The New Stack



"A service mesh is a dedicated infrastructure layer for managing service-to-service communication to make it visible, manageable, and controlled
...
The service mesh is implemented as infrastructure that lives outside of your applications. Its value is primarily realized when examining management of RPCs (or messages), but its value extends to management of all inbound and outbound traffic. Rather than coding that remote communication management directly into your apps, they can instead utilize a series of interconnected proxies (or a “mesh”) where that logic can be decoupled from your apps and unburden that responsibility from developers.


features:
  • Resiliency features (retries, timeouts, deadlines, etc)
  • Cascading failure prevention (circuit breaking)
  • Robust load balancing algorithms
  • Control over request routing (useful for things like CI/CD release patterns)
  • The ability to introduce and manage TLS termination between communication endpoints
  • Rich sets of metrics to provide instrumentation at the service-to-service layer"

Cloud: Static Website Hosting

With Web SPA (Single Page Apps), there is often no need for full featured web server.
Hosting static web files is enough, in combination with cloud functions.
That is faster, safer, and much more affordable solution. Now also available on Azure:

Static website hosting for Azure Storage now in public preview | Blog | Microsoft Azure

"When you enable static websites on your storage account, a new web service endpoint is created of the form

..web.core.windows.net.

The web service endpoint always allows anonymous read access, returns formatted HTML pages in response to service errors, and allows only object read operations. The web service endpoint returns the index document in the requested directory for both the root and all subdirectories."



Azure IoT Edge + Kubernetes

Using K8S to manage deployment of containers to remote locations,
by connecting to IoT hub and IoT Edge via "virtual kubelet."

Manage Azure IoT Edge deployments with Kubernetes | Blog | Microsoft Azure

"...leverage the Virtual Kubelet project which allows Kubernetes nodes to be backed by other services and make direct use of Kubernetes primitives. We implemented an IoT Edge provider, depicted by blue boxes in the below diagram, that transforms Kubernetes manifests to IoT Edge deployment manifests. A IoT Edge manifest can use tags to target on-prem edge devices whose configuration can be updated with a single kubectl command"
