I was invited to an AWS organization.
Now, after I logged into AWS Console as root user, I could not see anything created by the organization in (lambda, s3, etc).
Is there any additional step I should take except accepting the invitation?
Or is this some config missing on the organization side?
Thank you
AWS Organizations is a way of combining individual AWS Accounts into a hierarchy. Billing can 'roll-up' the hierarchy and permissions can 'go down'.
However, when you login to a specific AWS Account, you will only be able to view/access resources in that particular account. If you wish to view/access resources in another account within the organization, you could need to use an IAM Role to login to that other account.

Let's assume in current AWS organization we have 2 developers accounts. From what I found it is a good practice to create a separate AWS account per environment and give access to these resources.
My question is:
What is the best way to share access to the resources (e.g. EC2, EKS, EFS) for multiple developers? Now I see only these two options:
Create a separate AWS account for each developer and allow to access some resources by applying roles to that developers AWS accounts.
Within a root account of each AWS environment create a IAM user account for each developer and from that point manage permissions by policies and user groups.
Please let me know. I appreciate any type of help! :)
You should setup AWS SSO. Either integrated with your existing identity provider, or using the built in user system.
https://docs.aws.amazon.com/singlesignon/latest/userguide/what-is.html
This will allow you to create permission sets. Then, you can assign permission sets to users in particular accounts. This will create a role in the account which the users can assume
I am looking to provide a separate sandbox environment for my users. A concept similar to GCP Projects. Requirements are:
Each user should have only access to his own resources.
User should not be able to see the resources of other users.
Users should be able to create overlapping resources e.g user1 can create a VPC with 10.1.0.0/16 and user2 should be able to create the VPC with 10.1.0.0/16.
If there are any other options besides IAM, I am happy to opt.
To achieve these goals, you should provision a separate AWS Account for each user.
Each Account can be linked back to a master account using AWS Organizations.
I'm totally new to AWS and learning about IAM. I was wondering if there is a way around for an IAM user to check what all permission he/she have? Like as a root user, I created a group of IAM users where they were only allowed to use S3 service but once I logged in as an IAM user, it was showing that I have access to other AWS services as well like running EC2 instances, etc which I reckon shouldn't be the case. Thanks!
No, it isn't possible to "show" which services you have access to use, because the policies can be quite complex (eg permission to access an S3 bucket, but only a particular sub-folder if coming from a given range of IP addresses).
You would need to look the the IAM Policies attached to the IAM User, plus the policies on any IAM Groups they are in. Then, some services like Amazon S3 have additional permissions such as Bucket Policies.
In addition, AWS Organizations can limit the permissions of all users within an AWS Account, so even if a user appears to be granted certain permissions, they might not actually be available for use.
In many situations, you'll only know if you can do something by actually trying it. For example, you might have Read Only permissions, which means you can see resources in the AWS Console, but you would receive an error when you try to change things.
All services are available in the AWS Console, but various parts of the console will only work if you have adequate permission.
Note that there's IAM Policy Simulator from AWS. You can select a service and check if a given user has access to any given action (or all actions relevant to a service)
This question may seem noobish, but I am pulling my hair out with our AWS organization. We have 3 separate root accounts connected in a single organization with IAM accounts and policies. We can only see instances from the default root account in the EC2 list (yes I am looking in the correct region). We have shared full account access across all of the others accounts and accepted the invitations. Our billing works perfectly, and funnels from our main root account (and I can see billing of the other separate accounts fine). Even our highest level of admin (literally a grant permission to everything) cannot see instances launched from one of the separate root accounts.
Our goal is our admin group should see EC2 instances from all 3 root accounts in the organization without switching accounts or credentials.
I know this has to be possible, but I have spent at least 2 hours and have not gotten far. Any suggestions on how to achieve this?
There are some terminology issues here. There are no root accounts or main root accounts in AWS Organizations. There is one management AWS account and there are zero or more member AWS accounts.
The term root refers to an AWS Organizations construct within the management account that is the parent container for all of the member accounts in your organization. See AWS Organizations Terminology and Concepts for more.
There are two ways to 'join' a member account to an organization:
an admin in the management account creates a new member account
an admin in the management account invites an existing account to become a member
If you use option #1, administrative control over the member account is automatically provided for you through an auto-created IAM role called OrganizationAccountAccessRole that you can use to grant users in the management account administrator access to the created member account.
If you use option #2, you do not automatically have full administrator control over the member account. If you want the management account to have full administrative control over an invited member account, you must create the OrganizationAccountAccessRole IAM role in the member account and grant permission to the management account to assume the role. To configure this, after the invited account becomes a member, follow the steps in Creating the OrganizationAccountAccessRole in an Invited Member Account.
#jarmod's answer provides a good overview of the terminology. I don't think it addresses your visibility problem.
Your assumptions appears to be that the master account of the organization should be able to directly see all resources of all accounts within the organization in its AWS console or via the API. That's not correct.
The resources in the accounts are generally still separated (allthough some things can be shared, but that's another matter), but you can change into these accounts by assuming a role in the accounts and then you're able to see the resources - this is what #jarmod is describing. After you changed into the accounts, you'll be able to see all resources within that respective account.
To learn more about organizations and their capabilities, here are some helpful links:

Services that can be used in conjunction with organizations
Resources within an AWS Account logically belong to that account and not to its organization.
I would like to write a policy for a new IAM user so that he can have a full access to AWS Services such as EC2, RDS, Cloud Front, S3, etc. However he should be only able to view (describe) and manage the instances/services that he launches. He can't see other existing/future instances/services created by other users.
This case happens in a company that wants to outsource some projects to an outsourced company. So the new IAM user is for giving access to the outsourced company to setup the staging & production environments in AWS that belongs to the company. How can I achieve this?
Thanks.

AFAICT there are no conditions on creator.
One obvious alternative is having a separated dependent and linked account with consolidated billing. You can find some detail in the third scenario of this paper
https://media.amazonwebservices.com/AWS_Setting_Up_Multiuser_Environments_Education.pdf
[...] an administrator creates separate AWS accounts for each user who
needs a new AWS account. These accounts can optionally be linked
together and a single AWS account can be designated as the paying
account using consolidated billing, which provides a single bill for
multiple AWS accounts. The administrator then creates an IAM user in
each AWS account and applies an access control policy to each user.
Users are given access to the IAM user within their AWS account, but
do not have access to the root credentials of the AWS account.
Users can log into the AWS Management Console with their IAM
credentials and then they can launch and access different AWS
services, subject to the access control policies applied to their
account. Users have direct control over the access credentials for
their resources and they can also share these resources with other
users as necessary.
