OpenLegacy Modernization Guide

OpenLegacy creates microservices from legacy systems like CICS and IMS. It uses a design-time workbench to define services and a runtime engine to execute them. The platform supports web services, RESTful APIs, and JSON.

OpenLegacy connects to legacy systems using standard protocols like TCP/IP and SNA. It transforms legacy data formats into modern formats like JSON. The platform uses a metadata-driven approach to map legacy data structures to microservice interfaces.

OpenLegacy supports various deployment options, including on-premises, cloud, and hybrid environments. It can be deployed on platforms like z/OS, Linux, and Windows. The platform integrates with containerization technologies like Docker and Kubernetes.

OpenLegacy uses a design-time workbench for service creation and configuration. The workbench provides a graphical interface for mapping legacy data structures to microservice interfaces. The platform also supports command-line interface (CLI) for administrative tasks.

OpenLegacy exposes RESTful APIs using standard HTTP methods like GET, POST, PUT, and DELETE. API endpoints follow a resource-based pattern, such as `/customers/{customerId}`. The platform supports JSON for request and response payloads.

OpenLegacy supports integration with Java, JavaScript, and other programming languages through its SDKs and APIs. Developers can use the SDKs to invoke microservices and handle data transformation. The platform also supports integration with API gateways and service meshes.

OpenLegacy uses configuration files in YAML or JSON format to define service metadata, connection parameters, and security settings. These files are typically stored in a repository and managed through a CI/CD pipeline. The platform also provides a web-based administration console for managing configuration parameters.

The main system components include the Design Tool, the Runtime Engine, and the Connector Framework. The Design Tool is used to create and configure microservices. The Runtime Engine executes the microservices. The Connector Framework provides connectivity to legacy systems.

OpenLegacy enables organizations to modernize legacy systems without replacing them. It reduces the cost and risk of modernization by creating microservices that expose legacy functionality as APIs. The platform also improves agility and time-to-market for new applications.

OpenLegacy helps organizations unlock the value of their legacy data and applications. It enables them to create new digital experiences by exposing legacy functionality as APIs. The platform also supports integration with cloud-native technologies and architectures.

OpenLegacy supports various use cases, including mobile enablement, API integration, and cloud migration. It can be used to create mobile apps that access legacy data and functionality. The platform also supports integration with API gateways and service meshes for managing APIs.

OpenLegacy supports authentication methods such as LDAP, SAML 2.0, and X.509 certificates. It integrates with enterprise identity providers for user authentication and authorization. The platform also supports multi-factor authentication for enhanced security.

OpenLegacy uses Role-Based Access Control (RBAC) to manage user permissions. It defines roles with specific privileges and assigns users to those roles. The platform also supports fine-grained access control based on attributes and policies.

OpenLegacy uses TLS encryption for communication between components. It also supports encryption of sensitive data at rest using AES-256 encryption. The platform adheres to industry standards and best practices for security.

OpenLegacy provides audit logging capabilities for tracking user activity and system events. It logs events such as login attempts, configuration changes, and data access. The platform also supports integration with security information and event management (SIEM) systems.

OpenLegacy provides a web-based administration console for monitoring system health and performance. It displays metrics such as CPU usage, memory consumption, and network traffic. The platform also supports integration with monitoring tools like Prometheus and Grafana.

OpenLegacy logs events to standard output and log files. It supports different logging levels, such as DEBUG, INFO, WARN, and ERROR. The platform also supports integration with centralized logging systems like Elasticsearch and Splunk.

OpenLegacy can be deployed on various platforms, including z/OS, Linux, and Windows. It supports containerization technologies like Docker and Kubernetes for deployment and management. The platform also provides a command-line interface (CLI) for administrative tasks.

OpenLegacy supports automated deployment and configuration through CI/CD pipelines. It provides APIs and command-line tools for automating tasks such as service deployment, configuration management, and testing. The platform also integrates with popular CI/CD tools like Jenkins and GitLab.
