Previous experience / background ● Softwareengineer & architect for 20+ years ● One of the original Yahoo!Mail engineers G Suite Dev Show ● Author of bestselling "Core Python" books (corepython.com) goo.gl/JpBQ40 ● Technical trainer, teacher, instructor, adjunct CS faculty ● Fellow of the Python Software Foundation Agenda & takeaways ● Introduction ● What ● Platforms ● How ● Inspiration ● Why ● Summary ● When Introduction Why are you here? 01 Serverless computing means opinionated logic-hosting containers in the cloud. Serverless: the what ● Misnomer ● "No worries" ● According to Forbes*: ○ Developers focus on writing code & solving business problems without having to worry about infrastructure. ○ Servers (physical & virtual) completely abstracted away from the user. * source: Forbes (May 2018) Serverless: the why ● Fastest growing segment of cloud* ● $1.9B (2016) and $4.25B (2018) ⇒ $7.7B (2021) and $14.93B (2023) ● What if you go viral? ● What if you don't? * in USD; source: Research and Markets (Feb 2017) & (Aug 2018) Broad ecosystem Database & Storage Data Analytics ML & AI Compute Smart Messaging assistants & chat DevOps G Suite APIs Google knows serverless serverless timeline Google Google Apps Script App Maker (2009; 2009) (2016; 2018) 2008 2009 2016 2019 ??? Google Google Google App Engine Cloud Functions Cloud Run (2008; 2011) (2016; 2017; 2018) (2019; TBD) Platforms GCP + G Suite 02 Google App Engine App-hosting in the cloud Why does App Engine exist? App Engine to the rescue!! ● Focus on app not DevOps ● Enhance productivity ● Deploy globally ● Fully-managed ● Auto-scaling ● Pay-per-use ● Familiar standard runtimes Hello World (3 files: Python "MVP") app.yaml runtime: python37 main.py from flask import Flask Deploy: app = Flask(__name__) $ gcloud app deploy @app.route('/') Access globally: def hello(): return 'Hello World!' https://PROJECT_ID.appspot.com requirements.txt Flask==1.0.2 Popular App Engine use-cases ● Mobile/tablet ● Consumer web apps ○ App backends ○ Unpredictable traffic ○ Cloud persistence ○ Scale (up or down) ● Social/gaming ● Business apps ○ Speed, scale ○ Enterprise ○ API integrations ○ Java & PHP runtimes ○ Personals/dating ○ Web or mobile Google Cloud Functions Function-hosting in the cloud Why does Cloud Functions exist? ● Don't have full app ○ No framework "overhead" (LAMP, MEAN...) ○ Microservices ● Event-driven ○ Triggered via HTTP or background events ○ Auto-scaling & highly-available ○ Pay per use ● Familiar development environment ○ Cmd-line or developer console ● Cloud Functions for Firebase Hello World (Python "MVP") main.py def hello_world(request): return 'Hello World!' Deploy: $ gcloud functions deploy hello --runtime python37 --trigger-http Access globally: https://GCP_REGION-PROJECT_ID.cloudfunctions.net/hello Google Apps Script Customized JS runtime for automation, extension, and integration with G Suite and other Google or external services Sheets-bound “Hello World!” Sheets-bound “Hello World!” Apps Script intro goo.gl/1sXeuD What can you do with this? This… with help from Google Maps & Gmail function sendMap() { JS var sheet = SpreadsheetApp.getActiveSheet(); var address = sheet.getRange("A2").getValue(); var map = Maps.newStaticMap().addMarker(address); GmailApp.sendEmail('[email protected]', 'Map', 'See below.', {attachments:[map]}); } Accessing maps from spreadsheets?!? goo.gl/oAzBN9 Google App Maker Low-code assistive development for custom business apps Got app licenses for sales, marketing & operations? BUT... Custom business apps: still no easy solutions What platform Who has access should I use? to my app? Who builds my app? If no resources, how do I do it myself? Is my app compliant? Who will pay Where do I host for it? my data? Google App Maker ● Low-code assistive development environment; Cloud SQL default ● Go from idea to app in minutes ● Drag-n-drop app building ● Many pre-made template apps ● Generates Apps Script code ● Requires at least G Suite Business Custom apps across use-cases Line of Business (LOB) Operational / Process Employee directory Lender limits Room scheduling Inventory management Budget tracking Content management Project & task tracking Legal contracts Meeting planning Student progress Security dashboard Travel approvals Google Cloud Run Container-hosting in the cloud The rise of containers ● Any language ● Any library ● Any binary ● Ecosystem of base images ● Industry standard Serverless not accessible to everyone... “Can you support language _______ ?” “How can we use existing binaries?” “We can’t be locked in.” “Why do I have to choose between containers and serverless?” Google Cloud Run to the rescue! ● Fully-managed serverless "CaaS" ○ Flexibility and portability of containers, but with the convenience of serverless ○ You app, your bundled container ○ Auto-scale, -provision, -config ○ Pay-per-use ● Anti-vendor lock-in, portable to: ○ Google-managed Kubernetes cluster (GKE) ○ Or your self-managed Kubernetes cluster .js .rb .go Code, build, deploy .py .sh ... ● Any language, library, binary ○ HTTP port, stateless ● Bundle into container HTTP State ○ Build w/Docker or ○ Google Cloud Build ○ From Container Registry... ● Deploy to Cloud Run https://yourservice.run.app Inspiration Sample apps & case studies 03 Custom intelligence in Gmail Analyze G Suite data with GCP Gmail message processing with GCP Star message Categorize images Message Cloud Trigger Cloud Extract Cloud notification Pub/Sub function Functions images Vision Gmail G Suite GCP Inbox augmented with Cloud Function Big data analysis to slide presentation Access GCP tools from G Suite Store big data results Visualize big data results Ingest data from Sheets Link to chart in Sheets Supercharge G Suite with GCP Application Apps Script request Big data analytics BigQuery Slides Sheets G Suite GCP What's Next? 04 Summary ● Google knows serverless ○ Over a decade of experience ○ Been doing it before term existed ○ Variety of products serving different business needs ● Inspiration ○ Big data-to-slide deck: bit.ly/2OcptaG ○ Gmail intelligence: cloud.google.com/blog/products/application- development/adding-custom-intelligence-to-gmail-with-serverless-on-gcp ● Products ○ 2008: cloud.google.com/appengine ○ 2009: developers.google.com/apps-script ○ 2016: cloud.google.com/functions ○ 2016: gsuite.google.com/appmaker ○ 2019: cloud.google.com/run Thank you!
