What the client needed

A firm needed the solution aspects of containerising applications to cloud: the scenarios in which an application is considered containerised, the phases and phase-wise activities, how small, medium and large containerisation efforts differ, and the general rules for effort estimation and the resource pyramid for the work.

The brief

The questions on the table

As the client wrote them, lightly shortened. Client and respondents are not named.

  1. Q1

    In which scenarios is an application considered containerised on cloud, and what is out of scope?

  2. Q2

    What are the phases and phase-wise activities of a containerisation?

  3. Q3

    How do small, medium and large containerisations differ in characteristics?

  4. Q4

    What are the effort-estimation rules and the typical resource pyramid?

The hours

What the work involved

  1. 01

    Scenario definitions

    Lift-and-shift into containers, refactor-to-containers and platform re-hosting on Kubernetes or OpenShift, with the characteristics that make an estate small, medium or large.

  2. 02

    Phase model

    Assessment, platform readiness, packaging, pipeline integration, testing and cutover, with activities per phase from the lead’s modernisation programmes.

  3. 03

    Estimation rules

    Effort per application by scenario and size, plus the platform and pipeline work shared across applications, with the pyramid used.

  4. 04

    Cross-check

    A cloud solution architect who ran OpenShift migrations at scale reviewed the rules.

  5. 05

    Working session

    With the client’s modernisation practice.
