Description

Introduction

As enterprises modernize their integration landscape, microservices architecture has become a foundational approach for building scalable, resilient, and cloud-native solutions. webMethods provides powerful capabilities to design, deploy, secure, and manage microservices using APIs, containers, and event-driven patterns.

This training introduces participants to microservices architecture concepts and demonstrates how to implement microservices using webMethods components such as Integration Server, API Gateway, Microservices Runtime, Docker, and cloud platforms. Participants will learn best practices for service decomposition, API-first design, deployment strategies, and operational governance.

By the end of this course, learners will be equipped to design, build, deploy, and manage microservices-based integration solutions using webMethods.

Prerequisites

1. Basic understanding of SOA and RESTful services
2. Working knowledge of webMethods Integration Server
3. Familiarity with APIs (REST/JSON, HTTP)
4. Basic understanding of cloud concepts (containers, CI/CD is a plus)
5. Exposure to Docker and Kubernetes (recommended but not mandatory)
6. Basic programming knowledge (Java or service-based development)
