36. App Engine App Engine Flexible What VM means for customers
    Execution Environment
    Where the code runs
    Optimised Sandbox
    Secured
    0 to N scaling
    GA
    GCE VM-Based
    Docker containers based
    in Beta
    Flexibility
    Any language, framework, or library
    Performance
    Up to 32 vCPUS or 208 GB of mem
    Networking stack Custom Cloud Platform networking
    stack
    One network
    ● VPN, direct, carrier connection options
    ● Connect App Engine instances to Compute Engine on
    private network
    Load balancer
    Autoscaler
    Custom Cloud Load Balancer
    Cloud Autoscaler
    More control
    Configure lower-level infrastructure services as necessary
    NoSQL
    Tasks & cron
    Integrated Decoupled More control
    ● Access NoSQL Datastore from any compute product
    ● Utilize Task Queues or Pub/Sub to facilitate
    intra-project communication
    Managed runtime
    support
    constrained Fully open-source
    compliant
    New runtimes
    Managed Node.js, Python 3, Java 8, PHP, Go

37. • Docker images hosted on gcr.io
    • Pure openjdk8: deploy a jar
    • Springboot, Vertx, SparkJava, etc…
    • Simple app.yaml
    • Pure Servlet 3.1: deploy a war
    • Jetty9, collaboration with the Jetty project
    • Simple app.yaml
    • For GAE Standard Apps: Jetty9 +Sandbox compatibility layer
    • Run Standard apps as is,
    • needs appengine-web.xml

38. The Java 8 Runtime Dockerfile FROM gcr.io/google_appengine/openjdk8
    ADD myspringbootapp.jar /app
    app.yaml runtime: custom / java
    vm: true
    api_version: 1
    runtime_config:
    jdk: openjdk8
    The Java 8 / Jetty 9.3 Runtime Dockerfile FROM gcr.io/google_appengine/jetty9
    ADD root.war $JETTY_BASE/webapps/
    app.yaml runtime: custom / java
    vm: true
    api_version: 1
    runtime_config:
    jdk: openjdk8
    server: jetty9
    The Java 8 / Jetty 9.3 Compact
    Runtime Dockerfile FROM gcr.io/google_appengine/jetty9-compat
    ADD . /app/
    appengine-web.xml true

39. app.yaml now controls Java runtimes
    (The compat runtime
    still needs
    appengine-web.xml)
    runtime: java
    vm: true
    api_version: 1
    handlers:
    - url: .*
    script: dynamic
    resources:
    cpu: .5
    memory_gb: 1.3
    disk_size_gb: 10
    automatic_scaling:
    min_num_instances: 1
    max_num_instances: 20
    cool_down_period_sec: 60
    cpu_utilization:
    target_utilization: 0.5
    env_variables:
    OAUTH2_CALLBACK: http://your-project-id.appspot.com/oauth2callback
    LOG_PATH: /var/log/app_engine/custom_logs

40. New tooling
    • Cloud SDK
    • fingerprinting
    • deploy app.yaml configurations
    • Maven Plugin for Cloud SDK
    • Automatic staging phase for GAE sandbox compat applications
    • or put app.yaml and Dockerfile in src/main/appengine directory
