Google Cloud Platform (GCP) is a cloud computing service by Google that offers hosting on the same supporting infrastructure that Google uses internally for end-user products like Gmail, Google Search, Maps, and YouTube.

Overview

  • Google Cloud Platform (GCP) high-level view:
    • Compute
      • App Engine
      • Kubernetes Engine (see Kubernetes)
      • Compute Engine
    • Storage
      • BigTable
      • Cloud Storage
      • Cloud SQL
      • Cloud Datastore
    • Networking
      • VPCs
      • Load Balancers
      • Cloud DNS
      • Cloud CDN
    • Stackdriver
      • Monitoring
      • Logging
    • Big Data
      • BigQuery
      • Pub/Sub
      • Dataflow
      • Dataproc
      • Datalab
    • Artificial Intelligence
      • Vision API
      • Speech API
      • Translate API
      • Machine Learning
Examples
  • Google Compute Engine – IaaS service providing virtual machines similar to Amazon EC2.
  • Google App Engine – PaaS service for directly hosting applications similar to AWS Elastic Beanstalk.
  • BigTable – IaaS service providing map reduce services. Similar to Hadoop.
  • BigQuery – IaaS service providing Columnar database. Similar to Amazon Redshift.
  • Google Cloud Functions – FaaS service allowing functions to be triggered by events without developer resource management similar to Amazon Lambda or IBM OpenWhisk.
Cloud Regions and Zones
  • Region
    • A Region is specific geographical location where you can run your resources
    • It is a collection of zones
    • Regional resources are available to resources in any zone in the region
    • They are frequently expanding
  • Zone
    • Zones are isolated physical locations within a region
    • Zonal resources are only available in that zone
    • Machines in different zones have no single point of failure

An effective disaster recovery plan would have assets deployed across multiple zones, or even different regions.

Standards, regulations, and certifications
GCP Certifications

Main

Cloud Resource Hierarchy
  • Provides a hierarchy of ownership
    • Identity and Access Management (IAM)
  • Provides "attach" points and inheritance for access control and organization policies
  • Hierarchy overview
    • Organization (not applicable to individual accounts)
    • Projects
    • Resources
Projects
  • Core organizational component of GCP
  • Controls access to resources (who has access to what)
  • Projects are where you create, enable, and use all GCP services
    • Per project basis
    • Permissions
    • Billing
    • APIs
    • Etc.
  • Projects have three identifying attributes:
    1. Project Name (user-friendly name)
    2. Project ID (aka Application ID; must be unique across GCP)
    3. Project Number (used in various places for identifying resources that belong to specific projects. For example, service account access names)

Identity and Access Management (IAM)

  • Who can do what on which resource
    • Members (who) are granted permissions and roles (what) to GCP services (resource) using the principle of least privilege
  • IAM -> Policy -> Roles + Identities
  • See predefined roles
  • Members (the "who")
    • Can be either a person or a service account
    • People via:
      • Google account
      • Google group (e.g., dev.team@thecompany.com)
      • G Suite Domain
      • Cloud Identity (organization domain that is not a Google domain/account)
    • Service account
      • Special type of Google account that belongs to your application, not an end user
      • Identity for carrying out server-to-server interactions in a project (e.g., local server back application writing data to Cloud Storage)
      • Identified with an email address:
        • <project_number>@developer.gserviceaccount.com
        • <project_id>@developer.gserviceaccount.com
      • Application access
  • Roles (the "what")
    • A collection of permissions to give access to a given resource
    • Permissions are represented as: <service>.<resource>.<verb> (e.g., compute.instances.delete)
    • Permissions vs. roles
      • Users are not directly assigned permissions, but are assigned roles, which contain a collection of permissions:
      Role                 List of permissions

                           compute.instances.delete
                           compute.instances.get
compute.instanceAdmin ---> compute.instances.list
                           compute.instances.setMachineType
                           compute.instances.start
                           compute.instances.stop
Primitive vs. Predefined (aka curated) Roles
  • Primitive Roles
    • Historically available GCP roles before Cloud IAM was implemented
    • Applied at Project-level
    • Broad roles:
    1. Viewer: read only actions that preserve state (i.e., cannot make changes)
    2. Editor: same as above + can modify state
    3. Owner: same as above + can manage access to project and all project resources + can setup project billing
  • When to choose Primitive Roles
    • When the GCP service does not provide a predefined role
    • When you only need broad permissions for a project
    • When you want to allow a member to modify permissions for a project
    • When you work in a small team where the team members do not need granular permissions
  • Predefined ("Curated") Roles
    • Provides much more granular access (e.g., prevent unwanted access to other resources)
    • Granted at the resource-level
    • Example: App Engine Admin (full access to only App Engine resources)
    • Multiple predefined roles can be given to individual users
IAM Policy
  • A collection of statements that define who has what type of access
  • A full list of roles granted to a member for a resource
  • IAM Policy hierarchy
    • Resource access is organized hierarchically, from the Organization down to the Resource(s)
    • Organization -> Project -> Resource(s) — parent/child format
    • Each child has exactly one parent
    • Children inherit parent roles
    • Parent policies overrule restrictive child policies

Interacting with GCP

  • There are three methods of interacting with GCP:
    1. Cloud console (web interface)
    2. Google Cloud SDK
    3. RESTful API
Google Cloud SDK
  • Command line interface (CLI) tools for managing resources and applications on GCP
  • Includes:
    • gcloud — many common GCP tasks
    • gsutil — interact with Cloud Storage
    • bq — interact with data in BigQuery
  • Can also be installed locally as a Docker image or run from within Cloud Shell (via the UI)
  • install
Cloud Shell
  • Interactive web-based shell environment for GCP, accessed from a web console
  • Easy to manage resources without having to install the Google Cloud SDK locally.
  • Includes:
    • A temporary Compute Engine virtual machine/instance
    • CLI access to the instance from a web browser
    • 5 GB of persistent disk storage
    • Pre-installed Google Cloud SDK and other tools
    • Language support for: Python, Go, Node.js, PHP, Ruby, and Java
    • Web preview functionality (especially useful for App Engine)
    • Built-in authorization for access to GCP projects and resources
  • Limitations
    • 1 hour time out for inactivity
      • Machine will terminate/self-delete
      • $HOME directory contents will be preserved for a new session
    • Direct interactive use only
      • Not for running high computational/network workloads
      • If in violation of GCP terms of use, session can be terminated without notice
    • For long periods of inactivity, home disk may be recycled (with advance notice via email)
      • If you need longer inactive period, consider either locally installed SDK or use Cloud Storage for long-term storage
RESTful APIs
  • "Intended for software developers" ~ Google
  • Programmatic access to GCP resources
    • Typically uses JSON as an interchange format
    • Uses OAuth 2.0 for authentication and authorization
  • Enabled via the GCP Console
  • Most APIs have daily quotas, which can be increased upon request (to Google Support)
  • You can experiment via APIs Explorer

Google Compute

There are multiple Compute options in GCP for hosting your applications, where "option" is the method of hosting:

  • Google Compute Engine (GCE)
  • Google Container Engine (deprecated)
  • Google Kubernetes Engine (GKE)
  • Google App Engine (GAE)
  • Google Cloud Functions

In the above list, each option is ordered from "highly customizable" (GCE) to "highly managed" (Google Cloud Functions).

Each option can take advantage of the rest of the GCP services. E.g.,

  • Storage
  • Networking
  • Big Data
  • Security

Google Compute Engine (GCE)

Google Compute Engine (GCE)
  • Infrastructure as a Service (IaaS)
  • Virtual Machines (VMs), aka "instances"
Connecting to a VM
$ gcloud compute --project "my-project-123456" ssh --zone "us-west1-b" "my-vm"

The above command will create SSH keys (stored in ~/.ssh by default). After that, you can use the private key to SSH into your VM: 

$ ssh -i ~/.ssh/google_compute_engine username@x.x.x.x
Compute Engine Metadata
  • The project metadata URL is: http://metadata.google.internal/computeMetadata/v1/project/
  • The instance metadata URL is: http://metadata.google.internal/computeMetadata/v1/instance/

Each URL returns a set of entries that can be appended to the URL. Project settings contain info (e.g., project ID). Instance settings contain info on disks, hostname, machine type, etc.

One can also set one's own values so that one can use them in code on the VM. 

$ curl -H "Metadata-Flavor: Google" "http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/token"
{"access_token":"aa00...","expires_in":3599,"token_type":"Bearer"}

$ curl -H "Metadata-Flavor: Google" "http://metadata.google.internal/computeMetadata/v1/project/"
attributes/
numeric-project-id
project-id
Preemptible VMs

Preemptible VMs are highly affordable, short-lived compute instances suitable for batch jobs and fault-tolerant workloads. Preemptible VMs offer the same machine types and options as regular compute instances and last for up to 24 hours. If your applications are fault-tolerant and can withstand possible instance preemptions, then preemptible instances can reduce your Google Compute Engine costs significantly.

Google App Engine (GAE)

  • Platform as a Service (PaaS)
  • Developers can focus on writing code, while GCP handles the rest
  • Build scalable web applications and mobile backends
  • It is a managed service
    • You never touch the underlying infrastructure
    • Deployment, maintenance, and scalability are handled for you
    • Reduces operational overhead
  • There are two environments available in GAE:
    1. Standard: supports Python, PHP, Go, and Java
    2. Flexible: (natively) supports Java 8, Servlet 3.1, Jetty 8, Python 2.7/3.5, Node.js, Ruby, PHP, .NET core, and Go (plus other runtimes, if using a custom Docker image)

Google Cloud Functions

  • Serverless environment for building and connecting cloud services
  • Event-driven
    • Function executes as a "trigger" in response to a cloud-based event
    • Simple, single-purpose functions
  • Write function code in either Node.js or Python 3
  • Example: A file is uploaded to Cloud Storage (event), function executes in response to event (trigger)
  • Easier and less expensive than provisioning a server to watch for events
  • Not available in all Regions. As of January 2019, available in:
    • us-central1 (Iowa, USA)
    • us-east1 (South Carolina, USA)
    • europe-west1 (Belgium)
    • asia-northeast1 (Tokyo, Japan)

Command Line Interface (CLI)

The Google Cloud SDK is a set of tools that you can use to manage resources and applications hosted on the Google Cloud Platform (GCP). These include the gcloud, gsutil, and bq command line tools. The gcloud command-line tool is downloaded along with the Cloud SDK.

Cloud Storage

Storage Classes
Storage Class Name for APIs and gsutil
Multi-Regional Storage multi_regional
Regional Storage regional
Nearline Storage nearline
Coldline Storage coldline

See: for details


  • Create a bucket:
$ PROJECT_NAME=my-project
$ REGION=us-west1
$ STORAGE_CLASS=regional
$ BUCKET_NAME=xtof-test

# Basic (using defaults):
$ gsutil mb gs://${BUCKET_NAME}

# Advanced (override defaults):
$ gsutil mb -p ${PROJECT_NAME} -c ${STORAGE_CLASS} -l ${REGION} gs://${BUCKET_NAME}

Note: All buckets (and their objects) are private by default.

  • Upload an object to the above bucket:
$ gsutil cp Pictures/foobar.jpg gs://${BUCKET_NAME}
  • Move an object (file) from one bucket to another:
$ gsutil mv gs://${SOURCE_BUCKET} gs://${DESTINATION_BUCKET}
  • List the contents of a bucket:
$ gsutil ls gs://${BUCKET_NAME}     # basic info
$ gsutil ls -l gs://${BUCKET_NAME}  # extended info
Identity and Access Management
  • Get the IAM roles and rules for a given bucket (note: these are the default ones):
$ gsutil iam get gs://${BUCKET_NAME}

{
  "bindings": [
    {
      "members": [
        "projectEditor:my-project-123456", 
        "projectOwner:my-project-123456"
      ], 
      "role": "roles/storage.legacyBucketOwner"
    }, 
    {
      "members": [
        "projectViewer:my-project-123456"
      ], 
      "role": "roles/storage.legacyBucketReader"
    }
  ], 
  "etag": "CAE="
}
Lifecycle Management
  • Find all objects in a given bucket older than 2 days (i.e., when they were uploaded to the bucket or last modified) and convert them from "regional" to "nearline" storage class:
$ cat << EOF > lifecycle.json
{
  "lifecycle": {
    "rule": [
      {
        "action": {
          "type": "SetStorageClass",
          "storageClass": "NEARLINE"
        },
        "condition": {
          "age": 2,
          "matchesStorageClass": [
            "REGIONAL"
          ]
        }
      }
    ]
  }
}
EOF

$ gsutil lifecycle set lifecycle.json gs://${BUCKET_NAME}/
Signed-URLs

First, create a Service Account, with just enough privileges to modify Cloud Storage, and add and download the assigned key. 

$ gsutil cp test.txt gs://xtof-sandbox/
$ gsutil signurl -d 3m key.json gs://xtof-sandbox/test.txt

The above will return a signed-URL (it will look something like https://storage.googleapis.com/xtof-sandbox/test.txt?x-goog-signature=23asd...), which you can send to users and will only be valid for 3 minutes. After 3 minutes, they will get an "ExpiredToken" error.
