    Kubernetes secrets and Docker env variables in FE projects

    After moving to Micro-services architect, and by using a framework like Kubernetes, the need to store all configuration and variables in an easy to access place appears. And that is the main benefits of Kubernetes secrets. One of the challenges is to find a way to pass these parameters to a front-end project either if its pure JS project or written in one of the famous platforms now (React, Angular and Vue).

    Tracing in Node.js with Zipkin

    When companies began moving towards Microservices architect, the need of tracing the packets between services appeared to understand and fix bugs and troubleshoot latency problems in service architectures. While logs can tell us whether a specific request failed to execute or not and metrics can help us monitor how many times this request failed and how long the failed request took, traces help us debug the reason why the request failed or took so long to execute by breaking up the execution flow and dissecting it into smaller events.

    CI/CD pipeline for Fission.io

    Fission is a framework for serverless functions on Kubernetes. Whenever your functions increase more and more managing them will be harder, especially synchronizing the code between development and production environments. That time the CI/CD pipeline will be the best solution.

    A pattern for SaaS products in EF

    Entity Framework is an object-relational mapper (ORM) that enables .NET developers to work with a database using .NET objects. It eliminates the need for most of the data-access code that developers usually need to write. In some contexts like SaaS products you may need to apply a specific filter for any operation that happens on the database level, and you don’t want to include that in all your repository layer functions, so in this article, I will discuss an easy way to implement that.
