Processing Email using Microsoft Flow + Webhooks

One of the application development team had a requirement to read emails sent to a specific email address so that they can parse the same and act on them. We use Office365 and app team wanted to open up IMAP ports and the Security team and Email Admin teams had said "NO".

I didn't want to travel back in time.
The easier way would be to use Microsoft Flow with HTTP.

We use TYK API Gateway on our production network which is accessible on the internet and it is being used, but you can also any of your internet accessible endpoints like the app by itself or AWS API Gateway, etc.

Also, keep in mind the licensing requirements imposed by Microsoft for using Flow. From what I read, one should be able to do this from a shared mailbox as well.

Here are the high-level steps that I recommended the app team

1) Login into the Flow.
2) Create a new Flow ( Automated Flow from Blank )
3) Provide a name for the flow and select when a new email arrives as the trigger.

4) Expand and update advanced options to specify conditions to be met for this flow to be triggered. 

5) Add new step and search for http and select the one reads HTTP with Premium label

6) Specify your API Method (typically Post), API URI endpoint, Authentication Methods (highly recommended), make the best use of Dynamic Content and Expressions

7) Save the flow end test emails and see the upstream app receives the web call. Typically user agent is something like azure-logic-apps/1.0 (workflow 0123456789abcdef0123456789abcdef; version 0123456789abcdef) microsoft-flow/1.0

Few open source grid computing softwares --- quite interesting Gridgain - Completely built on Java with the below key features Advanced Affinity Map/Reduce Annotation-based grid-enabling with AOP SPI-based integration and customization Advanced load balancing and scheduling Pluggable Fault-Tolerance One compute grid - many data grids Zero deployment model JMX-based Management & Monitoring   BOINC A software platform for volunteer computing and desktop grid computing. BOINC is designed to support applications that have large computation requirements, storage requirements, or both. The main requirement of the application is that it be divisible into a large number (thousands or millions) of jobs that can be done independently. BOINC is used by SETI@home   NGrid is an open source (LGPL) grid computing framework written in C#. NGrid aims to be platform independent via the Mono project.

TYK API Gateway to AWS API Execute Gateway + Lambda

Image
TYK API Gateway  does not provide a simple integration for invoking Lambda and I remember reading Kong does.  In any case, this is about how to securely integrate TYK with Lambda - Or in general, consuming internal/private AWS Api gateway in your application. Here are the high-level steps  1) Create a VPC Endpoint for API Gateway - with a security group that allows 443 from the TYK Node/application nodes ( Security-group in the source is the best choice). Note the Endpoint ID (used  for API Gateway Resource Policy) and DNS Name (not the individual AZ but the generic one - to be used for API definition on TYK API Gateway ) 2) Create a Private AWS API gateway - with a nicely tied security group and the resource policy would look something like this ( replace highlighted place holders with your configurations)  {     "Version": "2012-10-17",     "Statement": [         {             "...

Effective CPU Utilizing with Parallel Extensions for .NET 3.5

Second CTP (Community Technology Preview) of Parallel Extension for .NET Framework 3.5 was released on June ( 2 nd ) . This enables utilizing of Parallel Hardware for application developed by .NET developers & improves performance as the numbers of cores and processors increases. With just a little bit of learning programmers can easily exploit the benefits of concurrent programming. Normally application would need parallelism for 2 things. a) Data Parallelism: Enables you to break problems into individual parallel units of work by partitioning data, like arrays, lists, loop iterations, or XML files. b) Task Parallelism: Provides more control over the expression of parallelism, enabling you to divide work based on the way your program's logic is grouped into functions and statements. Parallel Extensions for .NET 3.5 gives 2 flavors for Parallelism. Imperative parallelism : requires explicit calls to be made to begin and wait for work to finish. Declarative Parallelism: Hides ...
