GCP Project,Folder and Organization node


GCP resource hierarchy from the bottom up. All the resources you use--whether they’re virtual machines, Cloud Storage buckets, tables in BigQuery, or anything else in GCP are organized into projects.Optionally, these projects may be organized into folders; folders can contain other folders. All the folders and projects used by your organization can be brought together under an organization node. Projects, folders, and organization nodes are all places where policies can be defined. Some GCP resources let you put policies on individual resources too, like Cloud Storage buckets



Project:
All Resources belong to GCP console project. Projects are the basis for enabling and using GCP services, like managing APIs, enabling billing, adding and removing collaborators, and enabling other Google services. Each project is a separate compartment, and each resource belongs to exactly one. Projects can have different owners and users. They’re billed separately, and they’re managed separately.
Each GCP project has a name and project ID you assign. The project ID is apermanent, unchangeable identifier, and it has to be unique across GCP. You’ll use project IDs in several contexts to tell GCP which project you want to work with. On the other hand, project names are for your convenience, and you can change them. GCP also assigns each of your projects a unique project number, and you’ll see it displayed to you in various contexts, but using it is mostly outside the scope of this course. In general, project IDs are made to be human-readable strings, and you’ll use them frequently to refer to projects.
Folder:
Folders group projects under an organization. Folders can contain projects, other folders, or both. As in above image.
Organization node:
The organization node is the root node for Google Cloud resources.

Container and Container Orchestration

What is container? Container contain application code and dependencies into single Unit. So, what is Container orchestration? Container orchestration is about to managing life cycle of container. Container orchestration to control and automate task: Provisioning and deployment of container Scaling up and removing container as per application load Allocation the resource between Container Health check of container Kubernetes open Source is the example of Container Orchestration

Cloud Storage and Cloud IAM or ACLs or Signed URLs

Cloud Storage offers layers of increasingly granular access control. For most purposes, Cloud IAM is sufficient, and roles are inherited from project to bucket to object. Access control lists (ACL) offer finer control. And for detailed control, signed URLs provide a cryptographic key that gives time-limited access to a bucket or object. A signed policy document further refines the control by determining what kind of file can be uploaded by someone with a signed URL Cloud IAM Works with Cloud Storage just as with using Cloud IAM with any other resource. Project Owners are automatically granted Bucket Owner role for all buckets in the project. Note that ACLs and Cloud IAM are independent, so Project-level Cloud IAM permissions will not appear in bucket or object ACLs. Signed URLs A signed URL gives you the ability to grant access to a bucket without Cloud IAM user authentication for a limited period of time. e.g., when you don’t want to require users to have Goog...

Service Accounts

What if you want to give permissions to a Compute Engine virtual machine rather than to a person? That’s what service accounts are for. For instance, maybe you have an application running in a virtual machine that needs to store data in Google Cloud Storage. But you don’t want to let just anyone on the Internet have access to that data; only that virtual machine. So you’d create a service account to authenticate your VM to Cloud Storage. Service accounts are named with an email address, but instead of passwords they use cryptographic keys to access resources. Service Accounts control server-to-server interactions: Provide an identity for carrying out server-to-server interactions in a project Used to authenticate from one service to another Used to control privileges used by resources                 So that applications can perform actions on behalf of authenticated end users Identified with an ...
