WHAT IS CONTAINERIZATION?

WHAT IS CONTAINERIZATION?

Packaging of a configured application and all its dependenciesinto a light, portable, cloud-ready sandbox.

NEW POSSIBILITIES

Accelerated value delivery

1) Not every application fits into a container!

2) Containers are not only for elite-apps.

3) Conducted transformationsmust be driven by business value.

OPTIONS FOR CONTAINERIZATION

Change the underlying platform (runtime, framework, middleware, operating system).

Redesign code to take advantage of thenew platform (extend, strangle, rewrite).

Package existing application in a containerwith as few changes as possible.

Replace by Commercial off-the-shelf(COTS) or Software-as-as-Service (SaaS).

1. PORTFOLIO DISCOVERY & INVENTORY

HOW?

Use your favourite spreadsheet editor!

Automated

Manual

WHAT?

Identify and list existing assets (applications, infrastructure) in a central inventory.

Use some tools to automate the discovery process:● Agent(less) / Port & packet scan / SaaS or on-premise● Self written (e.g. with Ansible) vs. commercial offerings (e.g. CloudScape)● Use existing tools (CMDB, SOE, infrastructure as a code, CI/CD, app repository)

1. PORTFOLIO DISCOVERY & INVENTORY

Create an exhaustive list (spreadsheet) of all applications (plan, governance, estimates)

Relevant for prioritizationPlanning and scopeInternal application classification……..

Owners could be further split between ... technical lead / business owner / test owner / external providerCustom group for similar applicationsEXAMPLE

● Questionnaire-based frameworks● Automated code analysis tool

(e.g. RHAMT for Java applications)

2. READINESS ASSESSMENT

HOW?

Conduct interviews, workshops, code & document reviews (all levels).

Automated

Manual

WHAT?

1. Group similar applications based on their business & technical characteristics

2. Assess container-readiness

3. Identify the right transformationbased on business value

4. Estimate efforts

CONTAINER-READINESS FACTORS

Software architecture○ Monolith vs. Modular○ Coupling (loose vs. tight)○ State management○ Communication protocols○ CPU, IO, storage, connectivity needs○ Compliance, security, availability, resiliency requirements

SCOPING A TRANSFORMATION

● Business criticality, usage, user base● Application lifecycle (age)● Expected business value & efforts

WHAT?

Bridge existing and new platforms● Import assets of the existing application lifecycle

(source code, configuration, repositories, processes)● Reduce manual migration gaps

HOW?

● Automate import of all applications (no code change)○ Provide a “deploy-to-new-platform” button to devs○ Pre-generate templates and configuration

● Enable users (templates, guides)
