Azure Application Development

Azure Application Development — Service Areas

eAppSys delivers azure application development across six service areas — structured, expert, and built around your organisation’s objectives.

Azure App Service & Web Apps

  • ASP.NET Core, Java, Node.js, Python, PHP on App Service
  • Multi-tier architecture — front-end, API, and background service tiers
  • Deployment slots — blue/green deployments with production slot swap
  • App Service autoscale — scale-out triggers and scale-in policies
  • Static Web Apps for React/Vue/Angular with Azure Functions backend
  • App Service Environment (ASE) for compliance isolation requirements

Azure Functions & Serverless

  • HTTP, Timer, Service Bus, Blob, and Event Grid triggers
  • Durable Functions — stateful workflows, fan-out/fan-in, chaining
  • Integration with Oracle EBS and Fusion Cloud REST APIs
  • Consumption plan vs Premium plan selection per workload
  • .NET Isolated, Java, Node.js, Python, and PowerShell runtimes
  • Functions exposed via Azure API Management as managed APIs

AKS & Containerised Microservices

  • Microservices architecture design — domain decomposition, API contracts
  • AKS cluster — node pools, auto-scaler, availability zones, private cluster
  • Helm chart development for Kubernetes workload packaging
  • Service mesh — Istio for mTLS, traffic management, observability
  • Azure Container Registry (ACR) with geo-replication and scanning
  • CI/CD for AKS — GitHub Actions or Azure DevOps to ACR and AKS

Azure API Management

  • APIM deployment — Developer, Standard, or Premium tier
  • API policies — rate limiting, caching, OAuth 2.0, JWT validation
  • Developer portal for internal and external API consumers
  • Backend integration — Functions, App Service, Logic Apps, Oracle REST APIs
  • API versioning — path-based, header-based, or query string
  • API monitoring — Application Insights and APIM analytics

Power Platform & Low-Code

  • Power Apps — canvas and model-driven app development
  • Power Automate — approval workflows, data sync, and notifications
  • Power BI embedded analytics within operational applications
  • Dataverse — data modelling, business rules, security model
  • Power Platform governance — environment strategy, DLP policies, ALM
  • Custom connectors for Oracle Fusion Cloud and EBS integration

AI-Powered Applications

  • Azure OpenAI integration — GPT-4o, embeddings, and DALL-E
  • Azure AI Foundry — prompt flow, fine-tuning, AI evaluation
  • RAG — Azure AI Search + OpenAI for enterprise knowledge chatbots
  • Azure AI Document Intelligence — automated document processing
  • Azure Cognitive Services — Vision, Language, Speech in workflows
  • Oracle data as AI context — EBS/Fusion data in Azure AI applications

Why eAppSys

Your Azure Partner

All Compute Models

eAppSys delivers across App Service, Azure Functions, AKS, and Container Apps — the right compute model per workload, not a single technology applied to every problem.

AI Built In — Not Bolted On

Azure OpenAI and AI Foundry are integrated from the design phase — RAG chatbots, document intelligence, and AI-powered workflows are first-class application features.

API Management by Default

Every eAppSys Azure application is designed with Azure API Management as the integration layer — APIs catalogued, governed, rate-limited, and secured from day one.

Oracle + Azure Integration

eAppSys builds applications that integrate Oracle EBS and Fusion Cloud REST APIs with Azure-native services — Oracle data in Power Apps, Functions calling Fusion APIs, Entra ID federated with Oracle IAM.
Common Questions

Frequently Asked Questions

What Azure compute models does eAppSys develop on?
eAppSys develops on four models. Azure App Service: managed PaaS for web apps and APIs in .NET, Java, Node.js, Python, PHP. Azure Functions: event-triggered serverless — consumption-based pricing. AKS: containerised microservices for complex distributed applications. Azure Container Apps: simplified container hosting for microservices without full Kubernetes overhead. The right model is selected per workload based on complexity, scaling requirements, and operational model.
eAppSys integrates Azure OpenAI via three patterns. RAG: combining Azure AI Search vector search with OpenAI GPT models for knowledge base chatbots grounded in enterprise data. Document intelligence: Azure AI Document Intelligence for automated extraction from invoices, forms, and contracts. Generative workflows: Azure AI Foundry prompt flow for building, testing, and deploying AI workflows with evaluation and safety controls.
eAppSys delivers Power Apps (canvas and model-driven), Power Automate (approval workflows, data sync, notifications), Power BI (embedded analytics), Dataverse (data modelling, business rules, security), Power Platform governance (environment strategy, DLP policies, Centre of Excellence, ALM pipelines), and custom connectors for Oracle Fusion Cloud and EBS integration.
Oracle Fusion Cloud REST APIs are called from Azure Functions, Logic Apps, or APIM backends. Oracle EBS Integrated SOA Gateway exposes REST services consumed by Azure applications via APIM. OCI-hosted Oracle Autonomous Database is accessed from Azure via OCI-to-Azure network peering. Oracle identity is federated with Entra ID for single sign-on across Oracle and Azure applications.
Yes — eAppSys delivers Azure application development using an agile product model: sprint-based with a shared prioritised backlog. Features are prioritised by business value and delivered highest-value first in 2–4 week sprints. Sprint velocity is tracked and reported transparently. All code is deployed via CI/CD pipelines — no manual deployments to production Azure environments.
