Second Generation Runtimes More idiomatic code bases More portable applications More up-to-date runtimes >

gVisor Sandbox https://gvisor.dev/

More idiomatic code bases Past limitations are gone! Python ● Use Python 3 instead of Python 2 ● Any Python web framework ● Install arbitrary 3rd party dependencies (incl. native) ● Access the file system ● Spawn background threads ● Use Google Cloud client libraries >

More idiomatic code bases Past limitations are gone! Java ● Use Java 11 instead of Java 8 ● Any web framework (incl. non-Servlet based) ● No more class whitelist (Java2D, threads, sockets…) ● XML configuration → YAML configuration ● Customize entrypoint ○ JVM fine-tuning, executable JARs >

More portable applications Old App Engine built-in APIs ⇒ standalone cloud solutions ● Datastore → Cloud Datastore, Cloud Firestore, Cloud SQL ● Blobstore → Cloud Storage ● Cron → Cloud Scheduler ● Task Queues → Cloud Tasks ● Logging → Stackdriver Logging ● Memcache → Cloud Memorystore

More up-to-date runtimes And double the memory! Python 2.5 / 3.7 Java 8 / 11 ß Node.js 10 PHP 5.5 / 7.2 / 7.3 Ruby 2.5 ß Go 1.11 / 1.12
