    • 24. Pipelines as code

      The Pipeline as code technique advocates that the deployment pipeline configuration for building, testing, and deploying our applications or infrastructure should be treated as code.They should be placed under source control and best modularized into reusable components.


    • 52. C4Model

      The C4 model is an 'abstraction-first' approach to diagramming software architecture, based upon abstractions that reflect how software architects and developers think about and build software. The small set of abstractions and diagram types makes the C4 model easy to learn and use.

    • 53. Container Security Scanning
    • 54. Continuous Delivery
    • 55. Load Testing
    • 56. Service Mesh

      In software architecture, a service mesh is a dedicated infrastructure layer for facilitating service-to-service communications between services or microservices, using a proxy (often as a sidecar).

    • 57. Software Composition Analyses
    • 58. Static Application Security testing (SAST)


    • 74. Domain Driven Design
    • 75. Functional programming

      Functional Programming is a paradigm which is increasingly used in modern programming languages. Pure functions and immutability allow to write easily understandable, modular and fault tolerant code. We use functional programming to limit side effects and to be able to combine our code modules easily and test them well.

    • 76. GitOps

      GitOps is a paradigm or set of practices that enables developers to perform tasks that are normally part of IT operational authority. GitOps requires us to use declarative specifications to describe and observe the system.

    • 77. GraphQL
    • 78. Infrastructure as code Testautomation

      We rely on IaC with Terraform in our cloud projects. The larger the infrastructures there become, the more important automated testing of the landscapes created with code becomes here as well. Terratest currently seems to be emerging as a tool for this.
