Azure Functions (Serverless) Delivery

Build secure, scalable serverless solutions with Azure Functions - event-driven automation, API endpoints, integration glue, and operational-ready deployments.

Azure Functions is Microsoft’s serverless compute service for running event-driven code without managing infrastructure. Functions can be triggered by HTTP requests, timers, messages, and a wide range of Azure services, making it ideal for automation, integration, and lightweight API workloads. Microsoft documentation positions Azure Functions as a core component of serverless application architectures, supporting multiple languages and flexible hosting options.

LW IT Solutions delivers Azure Functions as production-grade engineering - not ‘just a function’. We design the right hosting model, security posture, and integration architecture; implement clean code patterns (including durable workflows where appropriate); and build CI/CD, monitoring, and runbooks so your serverless capability is supportable. This service is often used to connect systems, automate operational processes, expose APIs, and orchestrate event-driven workloads that need to scale reliably.

Talk through your requirements and leave with a clear next-step plan.

CI/CD and environment separation aligned to your release process
Operational monitoring and runbooks for ongoing support

Business Benefits

Rapid delivery of automation and integration logic without managing servers
Improved reliability through event-driven execution and managed scaling
Lower operational overhead using consumption-based or managed hosting models
Clear security posture with managed identity, secrets handling, and access control
Supportable serverless solutions with monitoring, alerting, and documented ownership

Typical use cases

Automating operational tasks triggered by events or schedules
Building lightweight APIs for internal or partner integrations
Connecting systems using queues, topics, or event streams
Implementing workflow steps to support Power Platform or AI solutions
Replacing fragile scripts or background jobs with managed serverless functions

Objectives & deliverables

What Success Looks Like

Automate business and IT processes using event-driven serverless patterns
Build lightweight APIs and integration endpoints without provisioning servers
Reduce operational overhead by using managed hosting, autoscaling, and consumption-based patterns
Improve reliability and observability of automations with monitoring, alerting, and controlled deployments
Accelerate delivery of integrations and workflow components that support wider platforms (Power Platform, AI, line-of-business apps)

What You Get

Azure Functions solution design pack: architecture, security model, and operational ownership
Implemented serverless functions (and durable orchestration if required) for the agreed scope
Infrastructure configuration guidance (hosting, identity, networking, secrets) aligned to your environment
CI/CD pipeline and deployment approach (as scoped)
Operational readiness pack: monitoring, alerting, runbooks, and support handover
Backlog: next functions, integration expansions, and hardening recommendations

How It Works

Discovery - confirm triggers/events, integrations, constraints, and success measures.
Design - define serverless architecture, security posture, and operational model.
Build - implement functions with structured patterns, testing, and configuration management.
Test - validate functional behaviour, failure paths, permissions, and performance considerations.
Deploy - controlled release via CI/CD and environment strategy.
Operate - establish monitoring/runbooks and handover to owners; plan iterative improvements.

Engagement Options

Function Delivery - Build one or more Azure Functions for a defined automation or API need
Integration Component - Serverless glue to connect systems, queues, and events
Durable Workflow - Orchestrated serverless workflows using Durable Functions
Stabilisation - Review and improve reliability, security, or observability of existing functions
