GPUs are a treasured useful resource; they’re each brief in provide and a lot more pricey than conventional CPUs. They’re additionally extremely adaptable to many alternative use instances. Organizations development or adopting generative AI use GPUs to run simulations, run inference (each for inner or exterior utilization), construct agentic workloads, and run knowledge scientists’ experiments. The workloads vary from ephemeral single-GPU experiments run by means of scientists to lengthy multi-node steady pre-training runs. Many organizations want to percentage a centralized, high-performance GPU computing infrastructure throughout other groups, industry devices, or accounts inside of their group. With this infrastructure, they may be able to maximize the usage of costly sped up computing sources like GPUs, fairly than having siloed infrastructure that could be underutilized. Organizations additionally use more than one AWS accounts for his or her customers. Better enterprises would possibly need to separate other industry devices, groups, or environments (manufacturing, staging, construction) into other AWS accounts. This gives extra granular keep an eye on and isolation between those other portions of the group. It additionally makes it easy to trace and allocate cloud prices to the precise groups or industry devices for higher monetary oversight.
The precise causes and setup can range relying at the measurement, construction, and necessities of the undertaking. However on the whole, a multi-account technique supplies better flexibility, safety, and manageability for large-scale cloud deployments. On this publish, we speak about how an undertaking with more than one accounts can get entry to a shared Amazon SageMaker HyperPod cluster for operating their heterogenous workloads. We use SageMaker HyperPod job governance to allow this option.
Resolution review
SageMaker HyperPod task governance streamlines useful resource allocation and offers cluster directors the potential to arrange insurance policies to maximise compute usage in a cluster. Job governance can be utilized to create distinct groups with their very own distinctive namespace, compute quotas, and borrowing limits. In a multi-account atmosphere, you’ll be able to limit which accounts have get entry to to which group’s compute quota the use of role-based access control.
On this publish, we describe the settings required to arrange multi-account get entry to for SageMaker HyperPod clusters orchestrated by means of Amazon Elastic Kubernetes Service (Amazon EKS) and the way to use SageMaker HyperPod job governance to allocate sped up compute to more than one groups in several accounts.
The next diagram illustrates the answer structure.
On this structure, one group is splitting sources throughout a couple of accounts. Account A hosts the SageMaker HyperPod cluster. Account B is the place the knowledge scientists are living. Account C is the place the knowledge is ready and saved for practising utilization. Within the following sections, we exhibit the way to arrange multi-account get entry to in order that knowledge scientists in Account B can educate a fashion on Account A’s SageMaker HyperPod and EKS cluster, the use of the preprocessed knowledge saved in Account C. We smash down this setup in two sections: cross-account get entry to for knowledge scientists and cross-account get entry to for ready knowledge.
Move-account get entry to for knowledge scientists
While you create a compute allocation with SageMaker HyperPod job governance, your EKS cluster creates a singular Kubernetes namespace according to group. For this walkthrough, we create an AWS Identity and Access Management (IAM) function according to group, known as cluster get entry to roles, which might be then scoped get entry to most effective to the group’s job governance-generated namespace within the shared EKS cluster. Role-based access control is how we be sure the knowledge science individuals of Workforce A won’t be able to put up duties on behalf of Workforce B.
To get entry to Account A’s EKS cluster as a person in Account B, it is important to think a cluster get entry to function in Account A. The cluster get entry to function can have most effective the wanted permissions for knowledge scientists to get entry to the EKS cluster. For an instance of IAM roles for knowledge scientists the use of SageMaker HyperPod, see IAM users for scientists.
Subsequent, it is important to think the cluster get entry to function from a task in Account B. The cluster get entry to function in Account A will then want to have a agree with coverage for the knowledge scientist function in Account B. The information scientist function is the function in account B that might be used to think the cluster get entry to function in Account A. The next code is an instance of the coverage remark for the knowledge scientist function in order that it may think the cluster get entry to function in Account A:
The next code is an instance of the agree with coverage for the cluster get entry to function in order that it lets in the knowledge scientist function to think it:
The overall step is to create an access entry for the group’s cluster get entry to function within the EKS cluster. This get entry to access must even have an get entry to coverage, equivalent to EKSEditPolicy, this is scoped to the namespace of the group. This makes positive that Workforce A customers in Account B can’t release duties out of doors in their assigned namespace. You’ll additionally optionally arrange customized role-based get entry to keep an eye on; see Setting up Kubernetes role-based access control for more info.
For customers in Account B, you’ll be able to repeat the similar setup for every group. You will have to create a singular cluster get entry to function for every group to align the get entry to function for the group with their related namespace. To summarize, we use two other IAM roles:
- Knowledge scientist function – The function in Account B used to think the cluster get entry to function in Account A. This function simply wishes so that you can think the cluster get entry to function.
- Cluster get entry to function – The function in Account A used to provide get entry to to the EKS cluster. For an instance, see IAM role for SageMaker HyperPod.
Move-account get entry to to ready knowledge
On this segment, we exhibit the way to arrange EKS Pod Identity and S3 Access Points in order that pods operating practising duties in Account A’s EKS cluster have get entry to to knowledge saved in Account C. EKS Pod Id permit you to map an IAM function to a provider account in a namespace. If a pod makes use of the provider account that has this arrangement, then Amazon EKS will set the surroundings variables within the packing containers of the pod.
S3 Get admission to Issues are named community endpoints that simplify knowledge get entry to for shared datasets in S3 buckets. They act so that you could grant fine-grained get entry to keep an eye on to express customers or programs having access to a shared dataset inside of an S3 bucket, with out requiring the ones customers or programs to have complete get entry to to all the bucket. Permissions to the get entry to level is granted via S3 get entry to level insurance policies. Every S3 Get admission to Level is configured with an get entry to coverage particular to a use case or software. For the reason that HyperPod cluster on this weblog publish can be utilized by means of more than one groups, every group may have its personal S3 get entry to level and get entry to level coverage.
Earlier than following those steps, be sure you have the EKS Pod Identity Add-on installed to your EKS cluster.
- In Account A, create an IAM Position that accommodates S3 permissions (equivalent to
s3:ListBucketands3:GetObjectto the get entry to level useful resource) and has a agree with courting with Pod Id; this might be your Knowledge Get admission to Position. Under is an instance of a agree with coverage.

}
]
}
- In Account C, create an S3 get entry to level by means of following the steps here.
- Subsequent, configure your S3 get entry to level to permit get entry to to the function created in step 1. That is an instance get entry to level coverage that provides Account A permission to get entry to issues in account C.

"Useful resource": [
"arn:aws:s3:::accesspoint/",
"arn:aws:s3:::accesspoint//object/*"
]
}
]
}
- Be certain that your S3 bucket coverage is up to date to permit Account A get entry to. That is an instance S3 bucket coverage:
{
"Model": "2012-10-17",
"Remark": [
{
"Effect": "Allow",
"Principal": "*",

"arn:aws:s3:::/*"
],
"Situation": {
"StringEquals": {
"s3:DataAccessPointAccount": ""
}
}
}
]
}
- In Account A, create a pod identification arrangement in your EKS cluster the use of the AWS CLI.
- Pods having access to cross-account S3 buckets will want the provider account call referenced of their pod specification.
You’ll verify cross-account knowledge get entry to by means of spinning up a verify pod and the executing into the pod to run Amazon S3 instructions:
This case displays making a unmarried knowledge get entry to function for a unmarried group. For more than one groups, use a namespace-specific ServiceAccount with its personal knowledge get entry to function to lend a hand save you overlapping useful resource get entry to throughout groups. You’ll additionally configure cross-account Amazon S3 get entry to for an Amazon FSx for Lustre record machine in Account A, as described in Use Amazon FSx for Lustre to share Amazon S3 data across accounts. FSx for Lustre and Amazon S3 will want to be in the similar AWS Area, and the FSx for Lustre record machine will want to be in the similar Availability Zone as your SageMaker HyperPod cluster.
Conclusion
On this publish, we equipped steering on the way to arrange cross-account get entry to to knowledge scientists having access to a centralized SageMaker HyperPod cluster orchestrated by means of Amazon EKS. As well as, we coated the way to supply Amazon S3 knowledge get entry to from one account to an EKS cluster in any other account. With SageMaker HyperPod job governance, you’ll be able to limit get entry to and compute allocation to express groups. This structure can be utilized at scale by means of organizations in need of to percentage a big compute cluster throughout accounts inside of their group. To get began with SageMaker HyperPod job governance, seek advice from the Amazon EKS Support in Amazon SageMaker HyperPod workshop and SageMaker HyperPod task governance documentation.
