Spring Cloud Microservices Example with Docker, Kubernetes, Kafka on Azure, AWS, GCP Spring Cloud Microservices Real-Time Architecture with Azure, AWS, GCP using Docker, Kubernetes, Kafka – Integrated with Mainframes, SAP, and Oracle Author: [Your Name] Date: June 10, 2025 Introduction Modern enterprise systems demand scalable, resilient, and cloud-agnostic architectures. Spring Cloud, coupled with Docker and Kubernetes, provides the foundation for building cloud-native microservices. This whitepaper presents a real-time microservices architecture deployed on Azure, AWS, and GCP, leveraging Kafka for communication and integrating with legacy systems like mainframes, SAP, and Oracle ERP. Architecture Overview This architecture contains: Spring Boot 3 microservices using Spring Cloud (Eureka, Config, Gateway) Containerized via Docker Orchestrated using Kubernetes on Azure AKS, AWS EKS, and GCP GKE Asynchronous communicatio...

Authentication and Authorization Design Patterns in Spring Boot 3 with Cloud Providers and Mainframes Authentication and Authorization Design Patterns in Spring Boot 3 with Spring Cloud for Azure, GCP, AWS Integrated with Mainframes Author: Naveen Kumar Gayar Published on: June 10, 2025 Introduction With enterprises transitioning to microservices and multi-cloud strategies, designing robust authentication and authorization (AuthN/AuthZ) mechanisms is critical. Spring Boot 3 and Spring Cloud offer powerful tools for building secure, cloud-integrated services. This whitepaper explores best practices and design patterns for implementing AuthN/AuthZ across cloud platforms (Azure, GCP, AWS) while maintaining secure communication with legacy mainframe systems. Architecture Overview The typical architecture includes: Spring Boot 3 microservices using Spring Security Cloud-native identity providers (Azure AD, Google IAM, AWS Cog...

Okay, here's a whitepaper on migrating Sybase (SAP ASE) databases to MySQL, formatted in HTML suitable for a Blogger.com post. ```html Whitepaper: Migrating Sybase (SAP ASE) Databases to MySQL Version: 1.0 Date: June 4, 2025 Abstract Migrating from Sybase Adaptive Server Enterprise (ASE), now SAP ASE, to MySQL presents an opportunity for organizations to leverage an open-source relational database management system (RDBMS) known for its cost-effectiveness, vibrant community, and wide range of integrations. This whitepaper provides a comprehensive guide to planning, executing, and managing the migration process. It covers key considerations including schema and data migration, application remediation, testing strategies, and post-migration best practices, aiming to equip organizations with the knowledge to navigate this complex transition successfully. 1. Introduction Many organizations are considering migrating from legacy database systems like Sybase (SAP ASE) to m...

When you're stepping in to lead a team, the coding interviews you conduct are a critical touchpoint. They're an opportunity to assess talent, but just as importantly, they're a reflection of your leadership style, technical competence, and the kind of environment you aim to build. Projecting professionalism and ensuring the process is transparent and fair is key to avoiding suspicion and building trust from day one. I. Setting the Stage: Pre-Interview Professionalism Technical & Logistical Readiness: Do: Master Your Tools: Be thoroughly familiar with the collaborative coding platform (e.g., CoderPad, HackerRank, shared IDE), video conferencing software, and any other tools you'll use. Test everything from your end – audio, video, screen sharing, and the coding environment itself. Why it matters: Fumbling with tools looks unprepared and can frustrate candidates. Do: Prepare Relevant & Standardized Questions: Design coding problems that ar...

Diving Deep: Mastering Backend Microservices with Spring Boot The world of backend development is increasingly moving towards microservice architectures. This approach offers scalability, resilience, and flexibility, allowing teams to develop, deploy, and manage services independently. If you're looking to specialize or upskill in a powerful backend technology for building these modern systems, focusing on Spring Boot for microservices is an excellent choice. This article will guide you through why Spring Boot is a dominant player in this space and what key aspects you should focus on. What Exactly Are Microservices? In simple terms, a microservice architecture is an approach to developing a single application as a suite of small, independent services. Each service runs in its own process and communicates with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment mach...

Key Insights from Technical Discussion on May 31, 2025 Date: May 31, 2025 This document summarizes the key topics, questions, and conclusions from our recent technical discussion. The session covered aspects of operating system architecture, virtualization, networking fundamentals, and software resources. 1. Operating System Architecture: 32-bit vs. 64-bit A consensus was reached regarding the current standard of 64-bit architecture. A key takeaway on compatibility was highlighted: A 32-bit operating system (OS) can be used on 64-bit hardware. However, a 64-bit OS cannot be used on 32-bit hardware. 2. Virtualization 🖥️ The discussion touched upon enabling and utilizing virtualization technology: Enabling Virtualization: Participants confirmed checking and enabling virtualization in their system BIOS/UEFI. Accessing BIOS/UEFI: Common keys to access BIOS/UEFI settings for enabling virt...

Developer Guide: Migrating TIBCO Web Services to Spring Boot 3 APIs This guide outlines a step-by-step process for migrating existing TIBCO Web Services to modern Spring Boot 3 RESTful APIs. This is a significant undertaking, requiring careful planning, execution, and testing. This guide assumes a basic understanding of Java, Spring Boot, RESTful principles, and familiarity with your existing TIBCO BusinessWorks (BW) processes. Phase 1: Assessment and Planning (The "Why" and "What") This is the most critical phase, laying the groundwork for a successful migration. Step 1: Inventory and Document Existing TIBCO Web Services Objective: Understand the current TIBCO landscape, its services, and their dependencies. Actions: List all TIBCO Web Services: Identify all SOAP/REST services exposed by TIBCO BusinessWorks. Service Definition: For each service, document: WSDL/OpenAPI (Swagger) Definition: Capture the...
