Authorization for a Multi-Cloud System

This is a project design I am currently working on to consume SPIFFE(Secure Production Identity Framework For Everyone) bootstrapped trust and identification to provide authorization in a dynamically scaling, heterogeneous system, inspired by Mr. Prabath Siriwardena from WSO2 and under the supervision of Prof. Gihan Dias from University of Moratuwa. An enterprise system running across multiple clouds, as in the hybrid cloud, is an obvious example that will be benefitted from this. The objective is to open doors for the SPIFFE standard based systems to co-exist with rest of the systems with minimal effort, without compromising on security aspects while having an authorization solution based on SPIFFE.
What is SPIFFE? In brief, it is a trust bootstrapping and identification framework, submitted as a standard and accepted by CNCF(Cloud Native Computing Foundation)[1]. As of now, this standard has two main implementations as SPIRE and Istio[2], a platform that supports service mesh archit…

Visualizing Code in Eclipse (Using Architexa)

I am here sharing a nice tool I recently found to draw the diagrams for my final year project at university. When the project is concerned, managing it is challenging with, 
  • code base of the project is pretty large
  • a team is working on the project
  • we need to maintain the quality and performance of the project 
  • proper documentation is also evaluated
So we were searching for an easy to use and nice looking tool to achieve the purposes without making it annoying that, we can focus more on the logic and optimization than decorating a diagram. :) That is were I found this plugin for eclipse called Architexa client, which is free for use.

Following is a sequence diagram I generated using the plugin, which didn't take more than 30s to draw than dragging the relevant classes and setting the relevant calls.

Following is a class diagram generated, that you can clearly observe the clear and smart look of the diagrams.


  1. From several tools that I have tried this was more faster and the diagram quality is great.
  2. It provides you the flexibility on deciding how the diagrams needs to be drawn, but to the rest on it's own.
  3. It provides sharing options with the tool that I am eager to try out.
  4. There several options to save and share the diagrams as images or files inside the project.
Rather than calling this cons, it is more suitable that I call them possible improvements that I haven't even seen them with any other freely available tool I tried.
  • This is little inconvenient to see generated members are not set in an orderly manner that always have to manually place them in order, as in following diagram.
Finally drawing diagrams has become fun, up-to date, truly useful and effective for code development for me. You can checkout whether it fits for you from here
I will share more experience with Architexa as I get more familiar. Cheers!


  1. Glad you find Architexa useful and thanks for the great post!

  2. Cool. Glad you also think Architexa is faster and results in better quality diagrams. We will definitely look into improving the automated diagram layout.
