通过 AWS Lambda，无需配置或管理服务器即可运行代码。您只需按消耗的计算时间付费 – 代码未运行时不产生费用。借助 Lambda，您几乎可以为任何类型的应用程序或后端服务运行代码，而且全部无需管理。只需上传您的代码，Lambda 会处理运行和扩展高可用性代码所需的一切工作。您可以将您的代码设置为自动从其他 AWS 服务触发，或者直接从任何 Web 或移动应用程序调用。
AWS Lambda是一项计算服务，依响应事件来运行您的代码并为您自动管理底层计算资源。您可以使用 AWS Lambda 通过自定义逻辑来扩展其他 AWS 服务，或创建您自己的按 AWS 规模、性能和安全性运行的后端服务。AWS Lambda 可以自动运行代码以响应多个事件，例如 Amazon S3 存储桶中对象的修改或 Amazon DynamoDB 中的表更新。
- 用自定义逻辑扩展其他 AWS 服务
- 内置容错能力， 可在各区域中跨过多个可用区维护计算容量
- 构建后端以处理 Web、移动、物联网 (IoT) 和第 3 方 API 请求
- 云发布/订阅（Cloud Pub/Sub）：任何异步的发布/订阅事件
- 云存储（Cloud Storage）：对象变更通知
Google Cloud Functions还在Alpha阶段，不受SLA限制，因此还不适合用在生产环境。

- Chalice (AWS Labs): An open source project that provides a Python serverless microframework for AWS that allows you to quickly create and deploy applications that use Amazon API Gateway and AWS Lambda. It makes assumptions about how applications will be deployed, and it has restrictions on how an application can be structured.
- Gestalt Framework (Galactic Fog): A set of microservices that are used together create a platform for application developers to build functionality without managing a container environment. The company is a Mesosphere partner, so may be one of the first ways to execute Lambda functions on Mesosphere’s Data Center Operating System (DC/OS).
- Serverless Framework (Serverless, Inc.): Serverless is an application framework for building web, mobile and IoT applications exclusively on Amazon Web Services’ Lambda and API Gateway. It’s a command line interface. The company behind it, Serverless, Inc. recently raised over $3 million in funding. The New Stack recently interviewed its creator, Austen Collins.
- Sparta (Open source project): Sparta offers a Go framework for AWS Lambda microservices. This project is led by NodeSource’s Matt Weagle. Sparta lets your Lambda-based service be integrated with the entire set of AWS lambda event sources. It also can provision CloudFormation supported resources.
- Zappa (Open source project): Serverless Python web services that make it easy to deploy Python WSGI applications (i.e., based on frameworks like Django and Flask), on AWS Lambda and API Gateway. A few months ago Ryan Brown conducted an interesting interview with founder Rich Jones.
- Apex (PubNub): Lets you build, deploy, and manage AWS Lambda jobs. Apex allows the use of non-natively supported language by using a Node.js shim injected into the build. Testing functions and other tooling is also part of the project, which is sponsored by PubNub.
- Funktion (Red Hat): An open source, event-driven, lambda-style programming model on top of Kubernetes. A funktion (note the funky spelling) is a regular function written in any language, but then connected to a trigger that is deployed into Kubernetes. When activated, these triggers work with endpoint URLs for databases, messaging systems and many other cloud services. The project is still experimental.
- Iron.io Platform (Iron.io): The platform includes IronWorker, IronMQ and IronCache, and is pre-integrated into many cloud-native platforms, such as Cloud Foundry, Kubernetes, Mesos and others.With IronWorker you can run AWS Lamba-like serverless functions from inside your firewall. IronWorker is a platform that isolates the code and dependencies of individual tasks to be processed on demand in a containerized environment. IronMQ is a distributed queue service and IronCache is a data service.
- Gordon (Open source project): Gordon is a platform to create, wire and deploy AWS Lambdas using CloudFormation. Jorge Bastida is the leading developer for this project.
- Nano Lambda (Nano Lambda): An automated compute service that runs and scales microservices. Code is uploaded into a container. Outside of the container, Nano Lambda will orchestrate the required tasks to network, secure, authenticate and log the micro-service. We learned about this emerging company from an Adrian Cockcroft presentation and look forward to seeing how their attempt to make money in the serverless space.
- Project Kratos (Iron.io): Still in beta, Project Kratos will enable enterprises to run AWS Lambda functionality in any cloud provider, as well as on-premise. Iron.io already offers another product, IronWorker, that can run AWS Lamba-like serverless functions that is pre-integrated into many cloud-native platforms.
- Syncano (Syncano): Syncano is a platform for building serverless apps, allowing users to customize sockets, which are configurations connected to Syncano services. It offers a dashboard and SDKs to define data schema. The company is among the most mature in the serverless space.
- IOpipe (IOpipe): IOpipe is analytics and distributed tracing service to monitor Amazon Lambda functions. Users add a module to their Lambda functions to get telemetry. IOpipe aggregates data, sends email reports and will provide a dashboard and metrics. Its founder is Eric Windisch, a Docker alum, was our podcast guest in both in 2014 and 2015.
- Kaazing WebSocket Gateway (Kaazing): This network gateway provides a single access point for real-time, web-based protocol elevation that supports load balancing, clustering, and security management. It is available in a free (community) and enterprise edition.
- Kappa (Open source project): Kappa is a command line tool that (hopefully) makes it easier to deploy, update, and test functions for AWS Lambda.
- LambCI (Open source project): LambCI is a continuous integration system built on AWS Lambda. It is a package you can upload to AWS Lambda that gets triggered when you push new code or open pull requests on GitHub and runs your tests in the Lambda environment itself. While founder Michael Hart launched LambCI with a compelling case to use it, there may not yet be a market for it as a commercial offering.
- Pusher (Pusher): Pusher is a hosted real-time messaging service with APIs, developer tools and open source libraries that simplify integrating real-time functionality into web and mobile applications.
- Vandium-node (Vandium Software): An AWS Lambda wrapper, Vandium is an open source npm module for protecting Node.js security using validation and protecting against injection attacks. This project and its eponymous company appear to be led by Richard Hyatt, a co-founder of BlueCat Networks.
- Dexter: Dexter is a platform that to connect third-party APIs. The development team is focusing on the “bot” use cases.
- Flourish (AWS): As we reported earlier in the year, Flourish will be an open source platform to manage components of serverless applications. Although it has not been released yet, Flourish gets a lot of mindshare among serverless developers.
- Form.io (Form.io): A combined form and API platform for Angular and React, Form.io simplifies connections between your forms and APIs.
- nstack (nstack): The nstack software turns a piece of code (such as a function, a class, or a library) into a lightweight microservice that can be bound to a stream of events. It used to be called Stackhut.
- Serverless Calculator (Serverless, Inc.): This calculator helps compare estimated costs across different FaaS providers, initially for AWS Lambda and Azure Functions. When Google Cloud Functions and IBM OpenWhisk set their pricing, this information will be included also.
- Stamplay (Stamplay): Stamplay connects APIs into service-based applications.
In so many emerging technology spaces, most companies are comprised mostly of manpower, implementing projects, not selling intellectual property. These companies are just a few examples.
