Microservices Architecture Corporate Training Course

This module discusses microservices architecture's evolution and monolithic systems' drawbacks. Modernizing monolithic architecture and the necessity for modularity, Service-Oriented Architecture (SOA), and its impact on microservices architecture are also important topics covered. SOA is defined and compared to monolithic architecture. This module also defines microservices and compares them to SOA. Teams learn about domain-driven design, microservices architecture design, and its benefits.

The microservices architecture's properties are highlighted in this module. REST architecture, designing for failure, and microservices inter-process connectivity are also covered. In addition, transaction management and microservices architecture pros and downsides are discussed towards the end of the module.

This module introduces the concept of domain-driven design. It decouples the user interface from the backend business logic and untangles monolithic programs to build autonomous services. Microservice design patterns and microservice architectural decisions are also covered.

Through this module, professionals learn Spring Boot and microservice development. It explains Spring Boot in detail and highlights how it facilitates microservice development. The module supports Java annotations, Lombok, Spring MVC, and REST services. Spring JAX-RS services and RestTemplate Java clients are also important topics covered. In addition, the module discusses Spring Boot dev tools, SQL databases, and WAR file conversion.

RESTful microservices, which are the most common, are explained in detail at the beginning of this module. It also covers RESTful service principles and SOAP service differences. Besides HTTP/2 vs. HTTP 1.1, messages, resources, and verbs, REST resource examples, RESTful services, and client-generated IDs are also among the important topics of this module. Moreover, professionals receive information on additional resources, Protocol Buffers, and JSON comparison.

In this module, teams learn about microservice security. Spring Security 3.0 and authentication and authorization are covered. Spring Security setup, programmatic versus declarative security, and examples are discussed in the module. LDAP, SAML, and database user authentication are explained in detail. The module also highlights OAuth2 and JSON Web Tokens (JWT) in microservices, OIDC, and microservice security.

The key highlight of this module is testing topics. It begins with Postman and Swagger's testing microservices. Further, it describes the Java REST service client and Angular HTTP Client, covering HTTP requests and error handling. The module also explains Observable objects, GET, POST, PUT, and DELETE queries, and other HTTP Client testing of microservices.

The chief topic of this module is Microservices Reference Architecture. This Spring Boot module implements configuration, discovery, API gateway, declarative REST client, fault tolerance, distributed caching, event-driven systems, distributed tracing, and monitoring. It covers reading properties in various ways, implementing a config server, setting up discovery server and client, understanding Actuator endpoints, using Hystrix for fault tolerance, implementing distributed caching and sessions, building event-driven systems, and monitoring microservices with Spring Boot Admin. Besides, it covers all microservices architecture tools and methods.

This module discusses Microservices logging difficulties and best practices. Correlating requests with a unique ID, delivering logs centrally, and formatting log data are covered. The focus is also on Fluent logs and Prometheus metrics. Topics such as Service discovery, Prometheus architecture, and service metrics are explained in detail. Prometheus querying concludes the module.

Design patterns for constructing robust, fault-tolerant, microservices-based applications are the key highlights of this module. It begins with Edge Proxy Server request handling and filtering, API Gateway routes requests, and limits rate. The Circuit Breaker pattern is discussed in detail, and it aims to prevent cascade failures and offer fault tolerance in microservices. This module covers Fail-Fast, Fallback, Thread Pooling, Request Caching, and Request Collapsing. Circuit Breaker/Fault tolerance solutions Hystrix and Resilience4j are compared. Server-side and client-side microservice load balancing are also explained. Topics such as Service Mesh and Content Delivery Network (CDN) benefits in microservices-based applications are discussed towards the end of this module.

Professionals learn Docker's features and usage. Installation, services, the docker application container public repository, and the docker command line include starting, inspecting, and stopping containers. The module also covers docker volume, dockerfile, docker-compose, container services and dependencies, runs overview, its capabilities, and container usage.

In this module, individuals understand Jenkins. The module covers various topics starting with Jenkins features and benefits for continuous integration. Individuals download and install Jenkins Learn how to run it as a standalone application, server, or Windows service. The module covers Jenkins tasks, source code management with SCM technologies such as Subversion and Git, build triggers, and schedules. Maven build steps, Jenkins pipeline, and plugin installation.

This module focuses on Creating a Jenkins pipeline to deploy microservices on the cloud.
