The operations manager asks you for a list of recommended practices that she should consider when migrating a J2EE application to the cloud.
Which three practices should you recommend? Choose 3 answers.
A. Port the application code to run on Google App Engine
B. Integrate Cloud Dataflow into the application to capture real-time metrics
C. Instrument the application with a monitoring tool like Stackdriver Debugger
D. Select an automation framework to reliably provision the cloud infrastructure
E. Deploy a continuous integration tool with automated testing in a staging environment
F. Migrate from MySQL to a managed NoSQL database like Google Cloud Datastore or Bigtable

you don’t need to provision infrastructure if you use App Enginer
A D E
Cannot be D.. Google will do the infrastructure for you
Cannot be C as The stack driver debugger is enabled by default for the Java runtime if you are using App Engine https://cloud.google.com/debugger/docs/setup/java
Do you need to provision the infrastructure when you are using App Engine? Can not be D
Google App Engine support Cloud Storage, Cloud Datastore, and Cloud SQL.
App Engine support store list Link : https://cloud.google.com/appengine/docs/standard/python/storage
But, when internet search, App Engine can use bigtable.
please, detail explain for me.

C: because integration with Stackdriver will allow for debugging.
D is not applicable as creating IAAC doesn’t help.
D is required cause still need to provison the creation app engine in an automation framwork such as terraform. that’s why terraform provide API/resources.
you can create app engine from the console but for a live project you will always want to do that with Infra as code.
A D E
AEF. A, For Java applications, App Engine provides a J2EE standard servlet container with a complete Java 7 JVM and standard library. Because App Engine supports common Java API standards, your code stays clean and portable.
E, When you migrate, you would not move you J2EE application directly to production, you would do some testing before roll to production. Ideally automation CI tool should use in staging to test the any changes introduce including code and configuration before roll into production.
F, In GAE you can access Datastore which is built on top of Google’s NoSQL database, Bigtable, and is subject to Bigtable’s performance characteristics.
Java Persistence API (JPA) is a standard interface for accessing databases in Java, providing an automatic mapping between Java classes and database tables. There is an open-source plugin available for using JPA with Datastore.
