#How To #Apply the #ScopeMaster® Across #Agile #Sprints

The article explains the gaps in applicability of ScrumMaster to individual Agile Spriner and describes the operational method that close these gaps and dramatically improved outcomes of ScopeMaster in application across increasing number of project sprints.

#Code of #DevOps #Practice

Code of DevOps Practice is an open proposal for organising creative work of DevOps in modern enterprise. The document includes: subject, cause, values, pillars and principles of the DevOps development as well as some best practice recommendations and a list of referred articles.

#Why We Need #Agile #Agility for #DevOps

While DevOps have elevated delivery velocity to the level that only Sun is higher and made it the goal and work effectiveness criteria (regardless quality), they still claim they are agile. The article takes a look into Agile Manifesto and Scrum Guide for the role of velocity. Neither the Agile Manifesto nor the latest version of the Scrum Guide (2017) reveals velocity at all, but have many loopholes inherited by DevOps.

Problems in #Microservice #QA and #Solutions

One of the major task of DevOps is a speedy delivery of Microservice into production. The major objective of QA and Testing is to find as many bugs as possible. Fixing these bugs slows down the delivery. The article describes this conflict in details, outlines problems in testing articulated by Mr Martin Fowler, proposes additional tests and explains how to improve quality of the released Microservices.

#Microservice #Protection based on the principle of #Zero #Trust

The task addressed in the article is about protecting Microservice’s functionality and resources in the inter-Microservice interactions. Known techniques like OpenID Connects, JWT and OAuth2 were reviewed from the perspective of Microservice interactions. It has been found that these techniques cannot be applied as-is to the Microservices either because unanswered questions to them or because of doubtful trustfulness of related workflows.
The article proposes two protective methods for Microservice (or service) that have sensitive functionality and/or resources. While the Basic Protection Method is just a classic identity verification and following access permission control, the method does not require single centralised Identity and Permission Authorities. The latter can be distributed as needed following the distribution of Microservice-based applications. The Closed Optimised Protection Method replaces Identity and Permission Authorities with Dependency Catalogue Service per application and provides full protection with performance comparable with OpenID-JWT/OAuth2.

Split and Join of #Functional and #Informational #Microservices

Article defines Functional Microservices using gRPC interface versus Informational Microservices accessible via RESTful interface. The Functional Microservices are validated against distortionless criteria. The code example of Interface definition for Functional Microservice is provided together with options allowing passing data together with function invocation.

#Distorted #Microservices

People like rubbish because it is convenient… Almost a Fairy-Tale about Microservices Are We Clear about What is What? Let’s Expose the ‘Devil’ that is Sitting in Details Distortions 1 to 12 A First Glance on Modelling Distortionless Microservices Almost a Fairy-Tale about Microservices Once upon a time, technology was conquered by marketing buzz and […]

#Contribution of #Architects into #Testing

Article discusses issues with modern light-weight testing applied via automation in DevOps practice and states that such testing is not necessarily enough for quality products, especially in the case of distribution in Cloud.
