The “legacy to cloud native kit” helps offer differentiated customer journeys through leveraging your legacy assets, and methodically transitioning select legacy functionality to a cloud native setup.

The kit renders ready-to-deploy digital tools, automation frameworks and services aligned to industry standards, to help you build scale and efficiency while standardizing cloud native components across group companies and reducing OpEx costs.

The processes and frameworks available to you, for a speedy implementation of your legacy modernization efforts, include:

Legacy decomposition process

The legacy decomposition process is an in-depth analysis of the legacy type and decision points that need to be considered to navigate your legacy estate. The framework makes provisions for:

In-house legacy systems, monoliths, evolved over many years
Third-party legacy systems that may not be supported today
Full-stack solutions that do not expose connectors/APIs needed for a cloud native setup

The process methodically identifies and simplifies decomposition into modular functional blocks that are then mapped to cloud native, interoperable components.

This initial stage also helps to categorize and analyze legacy systems that qualify and the ones that do not qualify for the migration process, to save on your costs and efforts.

Legacy migration process

The legacy migration process flow includes:

Pre-migration checklist

We draft a pre-migration checklist after conducting a detailed due diligence on your legacy estate, aligned to your business priorities. The checklist considers your specific scaling needs, efficiency needs and in-house development capabilities. It specifically addresses:

  • The legacy estate – Processes and customer journey dependencies on legacy, data model, security aspects, physical architecture, regulatory rules, training manuals etc.
  • Current business priorities – Inventory of new digital business models, envisaged customer journeys, digital channel features for the new models, security and current regulatory policies, scaling needs, data redundancy needs of the new cloud native setup etc.
Migration approach

The kit employs a 10-step approach to help you cut down costs and ensure the smooth running of your business operations. Each step is aided by tools and solution accelerators to standardize and expedite implementation:

  • Readiness assessment
  • Impact assessment
  • Migration and rollback solution design
  • Migration sandbox environment setup
  • Migration prototyping
  • Migration scripts development
  • Preliminary testing and dry run
  • Failure simulation and rollback dry run
  • Iterative migration execution
  • Decommissioning

Tools to standardize and accelerate migration:

The legacy to cloud native kit provides automation tools to accelerate every step of the journey:

A micro-gateway: DigitMarketTM API Manager

The DigitMarket™ micro-gateway is deployable as a standalone gateway instance to secure microservices. It has configurable usage policies (throttling, rate limiting, etc.) and security policies ( OAuth, HTTP-Basic, etc. ). A token-based authentication model makes it highly secure.

A visual integration tool: Coupler

‘Coupler’ is designed to model flows through configuration (drag-and-drop) and expose them on a micro-gateway. It supports multiple protocols such as SOAP, REST, JDBC, MQTT, JMS, etc. It offers node-based data flow modeling with configurable properties for each node.

A deployment automation tool: Deplomatic

Deplomatic is an advanced deployment automation tool. It is a container-based environment provisioning tool, built on Ansible, to provision a sandbox environment, for approval of workflow-based environment creation and continuous deployment. It can be exposed through APIs for easy integration into DevOps based workflows (continuous deployment).

A stubbing automation tool: AutoStub®

AutoStub® is an automation tool for API mocking. It has automatic data population capabilities configured for different response parameters. Its intelligent mocking capability helps design stateful data, across API invocations. The tool is used to create DevOps lifecycle automation for microservices by stubbing dependencies for each microservice to enable “testability” of each use case.

An API test automation tool: AutomatonTM

AutomatonTM is a test automation tool to test API flows using a visual approach. It is extensible. It can test beyond APIs. Its API-driven approach helps trigger tests from external scripts. It is used to create DevOps lifecycle automation for microservices through test automation for continuous integration. It can be configured to generate reports for each test execution.
