.NET Core Serverless 实战Azure Functions 与 AWS Lambda 部署指南Serverless 架构让开发者专注于业务逻辑无需管理服务器。本文将对比 Azure Functions 和 AWS Lambda 两大主流 Serverless 平台并给出 .NET Core 项目的完整部署方案。一、Serverless 核心优势| 特性 | 传统服务器 | Serverless | |------|-----------|------------| | 运维负担 | 高补丁、监控、扩容 | 极低 | | 成本模型 | 按资源预付费 | 按调用次数和时长付费 | | 自动扩容 | 需配置 | 原生支持 | | 冷启动 | 无 | 存在可优化 | | 适用场景 | 持续运行服务 | 事件驱动、间歇性负载 |二、Azure Functions 实战创建项目dotnet new func --name OrderProcessor cd OrderProcessor dotnet add package Microsoft.NET.Sdk.FunctionsHTTP 触发函数public static class OrderFunctions { [FunctionName(CreateOrder)] public static async TaskIActionResult CreateOrder( [HttpTrigger(AuthorizationLevel.Function, post, Route orders)] HttpRequest req, [CosmosDB(databaseName: orders, collectionName: items, ConnectionStringSetting CosmosDBConnection)] IAsyncCollectorOrderDocument orders, ILogger log) { log.LogInformation(Processing new order); var requestBody await req.ReadAsStringAsync(); var orderRequest JsonConvert.DeserializeObjectCreateOrderRequest(requestBody); var order new OrderDocument { Id Guid.NewGuid().ToString(), CustomerId orderRequest.CustomerId, Items orderRequest.Items, TotalAmount orderRequest.Items.Sum(i i.Price * i.Quantity), Status Pending, CreatedAt DateTime.UtcNow }; await orders.AddAsync(order); return new CreatedResult($/orders/{order.Id}, order); } [FunctionName(GetOrder)] public static IActionResult GetOrder( [HttpTrigger(AuthorizationLevel.Function, get, Route orders/{id})] HttpRequest req, [CosmosDB(databaseName: orders, collectionName: items, Id {id}, PartitionKey {id}, ConnectionStringSetting CosmosDBConnection)] OrderDocument order, ILogger log) { if (order null) { return new NotFoundResult(); } return new OkObjectResult(order); } }队列触发函数public static class OrderProcessingFunctions { [FunctionName(ProcessPayment)] public static async Task ProcessPayment( [QueueTrigger(payment-queue, Connection StorageConnection)] PaymentRequest paymentRequest, [CosmosDB(databaseName: orders, collectionName: items, ConnectionStringSetting CosmosDBConnection)] Docum
