Taming Serverless Dragons - Multi-Provider Serverless Apps

Serverless Framework has recently introduced support for multiple serverless providers You can now deploy serverless applications to OpenWhisk, Google Cloud Functions and Azure Functions as well as AWS Lambda. This allows you to develop platform-independent serverless applications. James Thomas has been working on the OpenWhisk implementation. In this talk, he will introduce the new feature, show you how to run serverless applications on different providers and explain the challenges in developing platform-agnostic serverless apps

2. PROVIDERS
3. WHY SWITCH PROVIDERS?
4. PERFORMANCE RUNTIMES OPEN-SOURCE MULTI-CLOUD
5. HERE BE DRAGONS
10. # serverless.yml service: my_service provider: name: aws functions: hello: handler: handler.hello # handler.js runtime: nodejs memory: 512 events: - http: GET /api/hello
11. # serverless.yml service: my_service provider: name: openwhisk functions: hello: handler: handler.hello # handler.js runtime: nodejs memory: 512 events: - http: GET /api/hello
12. RELEASE THE DRAGONS PLATFORMS

14. INTERFACES
15. // aws lambda exports.handler = function(event, context, callback) { callback(null, "some success message"); } // openwhisk exports.handler = function(params) { return {msg: "some success message"}; }; // azure functions module.exports = function(context, args...) { context.done(null, {msg: "some success message"}) }; // google cloud functions exports.handler = function(event, callback) { callback(null, "some success message"); };

23. supports six event sources supports fifteen event sources supports six event sources supports three event sources * - supports adding other event sources
24. INTERFACES RUNTIMES EVENTS SDKS
25. // aws lambda var aws = require('aws-sdk'); var lambda = new aws.Lambda(); var params = {FunctionName: 'id', Payload: JSONPayload}; lambda.invoke(params, function(error, data) { // do something }); // openwhisk var openwhisk = require('openwhisk'); var options = {apihost: 'openwhisk.ng.bluemix.net', api_key: '...'}; var ow = openwhisk(options); ow.actions.invoke({actionName: ‘...'}).then();
