Your multi-account technique is the core of your foundational atmosphere on AWS. Design choices round your multi-account atmosphere are crucial for working securely at scale. Grouping your workloads strategically into a number of AWS accounts lets you apply totally different controls throughout workloads, monitor value and utilization, cut back the influence of account limits, and mitigate the complexity of managing a number of digital personal clouds (VPCs) and identities by permitting totally different groups to entry totally different accounts which are tailor-made to their objective.
In Half 1 of this sequence, Governing the ML lifecycle at scale, Half 1: A framework for architecting ML workloads utilizing Amazon SageMaker, you realized about finest practices for working and governing machine studying (ML) and analytics workloads at scale on AWS. On this submit, we offer steerage for implementing a multi-account basis structure that may enable you arrange, construct, and govern the next modules: information lake foundations, ML platform companies, ML use case improvement, ML operations, centralized characteristic shops, logging and observability, and price and reporting.
We cowl the next key areas of the multi-account technique for governing the ML lifecycle at scale:
- Implementing the really useful account and organizational unit construction to offer isolation of AWS sources (compute, community, information) and price visibility for ML and analytics groups
- Utilizing AWS Management Tower to implement a baseline touchdown zone to help scaling and governing information and ML workloads
- Securing your information and ML workloads throughout your multi-account atmosphere at scale utilizing the AWS Safety Reference Structure
- Utilizing the AWS Service Catalog to scale, share, and reuse ML throughout your multi-account atmosphere and for implementing baseline configurations for networking
- Making a community structure to help your multi-account atmosphere and facilitate community isolation and communication throughout your multi-tenant atmosphere
Your multi-account basis is step one in the direction of creating an atmosphere that allows innovation and governance for information and ML workloads on AWS. By integrating automated controls and configurations into your account deployments, your groups will be capable to transfer shortly and entry the sources they want, understanding that they’re safe and comply along with your group’s finest practices and governance insurance policies. As well as, this foundational atmosphere will allow your cloud operations group to centrally handle and distribute shared sources similar to networking elements, AWS Id and Entry Administration (IAM) roles, Amazon SageMaker venture templates, and extra.
Within the following sections, we current the multi-account basis reference architectures, focus on the motivation behind the architectural choices made, and supply steerage for implementing these architectures in your personal atmosphere.
Organizational models and account design
You need to use AWS Organizations to centrally handle accounts throughout your AWS atmosphere. While you create a company, you possibly can create hierarchical groupings of accounts inside organizational models (OUs). Every OU is often designed to carry a set of accounts which have widespread operational wants or require an identical set of controls.
The really useful OU construction and account construction you need to think about to your information and ML foundational atmosphere relies on the AWS whitepaper Organizing Your AWS Atmosphere Utilizing A number of Accounts. The next diagram illustrates the answer structure.
Solely these OUs which are related to the ML and information platform have been proven. It’s also possible to add different OUs together with the really useful ones. The subsequent sections focus on how these really useful OUs serve your ML and information workloads and the precise accounts you need to think about creating inside these OUs.
The next picture illustrates, respectively, the structure of the account construction for establishing a multi-account basis and the way it will appear to be in AWS Organizations as soon as applied .
Advisable OUs
The really useful OUs embrace Safety, Infrastructure, Workloads, Deployments, and Sandbox. When you deploy AWS Management Tower, which is strongly really useful, it creates two default OUs: Safety and Sandbox. It’s best to use these default OUs and create the opposite three. For directions, consult with Create a brand new OU.
Safety OU
The Safety OU shops the varied accounts associated to securing your AWS atmosphere. This OU and the accounts therein are usually owned by your safety group.
It’s best to think about the next preliminary accounts for this OU:
- Safety Tooling account – This account homes basic safety instruments in addition to these safety instruments associated to your information and ML workloads. For example, you should use Amazon Macie inside this account to assist defend your information throughout your whole group’s member accounts.
- Log Archive account – When you deploy AWS Management Tower, this account is created by default and positioned inside your Safety OU. This account is designed to centrally ingest and archive logs throughout your group.
Infrastructure OU
Much like different varieties of workloads you can run on AWS, your information and ML workloads require infrastructure to function accurately. The Infrastructure OU homes the accounts that preserve and distribute shared infrastructure companies throughout your AWS atmosphere. The accounts inside this OU will probably be owned by the infrastructure, networking, or Cloud Heart of Excellence (CCOE) groups.
The next are the preliminary accounts to contemplate for this OU:
- Community account – To facilitate a scalable community structure for information and ML workloads, it’s really useful to create a transit gateway inside this account and share this transit gateway throughout your group. It will permit for a hub and spoke community structure that privately connects your VPCs in your multi-account atmosphere and facilitates communication with on-premises sources if wanted.
- Shared Companies account – This account hosts enterprise-level shared companies similar to AWS Managed Microsoft AD and AWS Service Catalog that you should use to facilitate the distribution of those shared companies.
Workloads OU
The Workloads OU is meant to accommodate the accounts that totally different groups inside your platform use to create ML and information purposes. Within the case of an ML and information platform, you’ll use the next accounts:
- ML group dev/check/prod accounts – Every ML group might have their very own set of three accounts for the event, testing, and manufacturing levels of the MLOps lifecycle.
- (Elective) ML central deployments – It’s additionally attainable to have ML mannequin deployments absolutely managed by an MLOps central group or ML CCOE. This group can deal with the deployments for your complete group or simply for sure groups; both means, they get their very own account for deployments.
- Information lake account – This account is managed by information engineering or platform groups. There could be a number of information lake accounts organized by enterprise domains. That is hosted within the Workloads OU.
- Information governance account – This account is managed by information engineering or platform groups. This acts because the central governance layer for information entry. That is hosted within the Workloads OU.
Deployments OU
The Deployments OU comprises sources and workloads that help the way you construct, validate, promote, and launch adjustments to your workloads. Within the case of ML and information purposes, this would be the OU the place the accounts that host the pipelines and deployment mechanisms to your merchandise will reside. These will embrace accounts like the next:
- DevOps account – This hosts the pipelines to deploy extract, rework, and cargo (ETL) jobs and different purposes to your enterprise cloud platform
- ML shared companies account – That is the primary account to your platform ML engineers and the place the place the portfolio of merchandise associated to mannequin improvement and deployment are housed and maintained
If the identical group managing the ML engineering sources is the one taking good care of pipelines and deployments, then these two accounts could also be mixed into one. Nonetheless, one group needs to be chargeable for the sources in a single account; the second you have got totally different impartial groups taking good care of these processes, the accounts needs to be totally different. This makes certain {that a} single group is accountable for the sources in its account, making it attainable to have the proper ranges of billing, safety, and compliance for every group.
Sandbox OU
The Sandbox OU usually comprises accounts that map to a person or groups inside your group and are used for proofs of idea. Within the case of our ML platform, this may be circumstances of the platform and information scientist groups desirous to create proofs of idea with ML or information companies. We advocate utilizing artificial information for proofs of idea and keep away from utilizing manufacturing information in Sandbox environments.
AWS Management Tower
AWS Management Tower lets you shortly get began with the perfect practices to your ML platform. While you deploy AWS Management Tower, your multi-account AWS atmosphere is initialized in line with prescriptive finest practices. AWS Management Tower configures and orchestrates extra AWS companies, together with Organizations, AWS Service Catalog, and AWS IAM Id Heart. AWS Management Tower helps you create a baseline touchdown zone, which is a well-architected multi-account atmosphere based mostly on safety and compliance finest practices. As a primary step in the direction of initializing your multi-account basis, you need to arrange AWS Management Tower.
Within the case of our ML platform, AWS Management Tower helps us with 4 primary duties and configurations:
- Group construction – From the accounts and OUs that we mentioned within the earlier part, AWS Management Tower gives you with the Safety and Sandbox OUs and the Safety Tooling and Logging accounts.
- Account merchandising – This lets you effortlessly create new accounts that comply along with your group’s finest practices at scale. It permits you to present your personal bootstrapping templates with AWS Service Catalog (as we focus on within the subsequent sections).
- Entry administration – AWS Management Tower integrates with IAM Id Heart, offering preliminary permissions units and teams for the fundamental actions in your touchdown zone.
- Controls – AWS Management Tower implements preventive, detective, and proactive controls that enable you govern your sources and monitor compliance throughout teams of AWS accounts.
Entry and identification with IAM Id Heart
After you identify your touchdown zone with AWS Management Tower and create the required extra accounts and OUs, the subsequent step is to grant entry to numerous customers of your ML and information platform. Proactively figuring out which customers would require entry to particular accounts and outlining the explanations behind these choices is really useful. Inside IAM Id Heart, the ideas of teams, roles, and permission units permits you to create fine-grained entry for various personas inside the platform.
Customers could be organized into two main teams: platform-wide and team-specific person teams. Platform-wide person teams embody central groups similar to ML engineering and touchdown zone safety, and they’re allotted entry to the platform’s foundational accounts. Crew-specific teams function on the group degree, denoted by roles similar to group admins and information scientists. These teams are dynamic, and are established for brand spanking new groups and subsequently assigned to their respective accounts upon provisioning.

You need to use these preconfigured teams to your platform’s central groups or create new customized ones. For additional insights into these teams, consult with IAM Id Heart Teams for AWS Management Tower. The next screenshot exhibits an instance of the AWS Management Tower console, the place you possibly can view the accounts and decide which teams have permission on every account.
IAM Id Heart additionally gives a login web page the place touchdown zone customers can get entry to the totally different sources, similar to accounts or SageMaker domains, with the totally different ranges of permissions that you’ve got granted them.
AWS Safety Reference Structure
The AWS SRA is a holistic set of tips for deploying the total complement of AWS safety companies in a multi-account atmosphere. It may enable you design, implement, and handle AWS safety companies in order that they align with AWS really useful practices.
To assist scale safety operations and apply safety instruments holistically throughout the group, it’s really useful to make use of the AWS SRA to configure your required safety companies and instruments. You need to use the AWS SRA to arrange key safety tooling companies, similar to Amazon GuardDuty, Macie, and AWS Safety Hub. The AWS SRA permits you to apply these companies throughout your whole multi-account atmosphere and centralize the visibility these instruments present. As well as, when accounts get created sooner or later, you should use the AWS SRA to configure the automation required to scope your safety instruments to those new accounts.
The next diagram depicts the centralized deployment of the AWS SRA.
Scale your ML workloads with AWS Service Catalog
Inside your group, there’ll probably be totally different groups akin to totally different enterprise models. These groups can have comparable infrastructure and repair wants, which can change over time. With AWS Service Catalog, you possibly can scale your ML workloads by permitting IT directors to create, handle, and distribute portfolios of authorized merchandise to end-users, who then have entry to the merchandise they want in a personalised portal. AWS Service Catalog has direct integrations with AWS Management Tower and SageMaker.
It’s really useful that you simply use AWS Service Catalog portfolios and merchandise to reinforce and scale the next capabilities inside your AWS atmosphere:
- Account merchandising – The cloud infrastructure group ought to preserve a portfolio of account bootstrapping merchandise inside the shared infrastructure account. These merchandise are templates that comprise the fundamental infrastructure that needs to be deployed when an account is created, similar to VPC configuration, normal IAM roles, and controls. This portfolio could be natively shared with AWS Management Tower and the administration account, in order that the merchandise are straight used when creating a brand new account. For extra particulars, consult with Provision accounts via AWS Service Catalog.
- Analytics infrastructure self-service – This portfolio needs to be created and maintained by a central analytics group or the ML shared companies group. This portfolio is meant to host templates to deploy totally different units of analytics merchandise for use by the platform ML and analytics groups. It’s shared with your complete Workloads OU (for extra info, see Sharing a Portfolio). Examples of the merchandise embrace a SageMaker area configured in line with the group’s finest practices or an Amazon Redshift cluster for the group to carry out superior analytics.
- ML mannequin constructing and deploying – This functionality maps to 2 totally different portfolios, that are maintained by the platform ML shared companies group:
- Mannequin constructing portfolio – This comprises the merchandise to construct, practice, consider, and register your ML fashions throughout all ML groups. This portfolio is shared with the Workloads OU and is built-in with SageMaker venture templates.
- Mannequin deployment portfolio – This comprises the merchandise to deploy your ML fashions at scale in a dependable and constant means. It’ll have merchandise for various deployment varieties similar to real-time inference, batch inference, and multi-model endpoints. This portfolio could be remoted inside the ML shared companies account by the central ML engineering group for a extra centralized ML technique, or shared with the Workloads OU accounts and built-in with SageMaker venture templates to federate duty to the person ML groups.
Let’s discover how we cope with AWS Service Catalog merchandise and portfolios in our platform. Each of the next architectures present an implementation to manipulate the AWS Service Catalog merchandise utilizing the AWS Cloud Growth Equipment (AWS CDK) and AWS CodePipeline. Every of the aforementioned portfolios can have its personal impartial pipeline and code repository. The pipeline synthesizes the AWS CDK service catalog product constructs into precise AWS Service Catalog merchandise and deploys them to the portfolios, that are later made out there for its consumption and use. For extra particulars in regards to the implementation, consult with Govern CI/CD finest practices by way of AWS Service Catalog.
The next diagram illustrates the structure for the account merchandising portfolio.
The workflow contains the next steps:
- The shared infrastructure account is about up with the pipeline to create the AWS Service Catalog portfolio.
- The CCOE or central infrastructure group can work on these merchandise and customise them in order that firm networking and safety necessities are met.
- You need to use the AWS Management Tower Account Manufacturing unit Customization (AFC) to combine the portfolio inside the account merchandising course of. For extra particulars, see Customise accounts with Account Manufacturing unit Customization (AFC).
- To create a brand new account from the AFC, we use a blueprint. A blueprint is an AWS CloudFormation template that will probably be deployed within the newly created AWS account. For extra info, see Create a personalized account from a blueprint.
The next screenshot exhibits an instance of what account creation with a blueprint appears to be like like.
For the analytics and ML portfolios, the structure adjustments the way in which these portfolios are used downstream, as proven within the following diagram.
The next are the important thing steps concerned in constructing this structure:
- The ML shared companies account is about up and bootstrapped with the pipelines to create the 2 AWS Service Catalog portfolios.
- The ML CCOE or ML engineering group can work on these merchandise and customise them in order that they’re updated and canopy the primary use circumstances from the totally different enterprise models.
- These portfolios are shared with the OU the place the ML dev accounts will probably be positioned. For extra details about the totally different choices to share AWS Service Catalog portfolios, see Sharing a Portfolio.
- Sharing these portfolios with your complete Workloads OU will end in these two portfolios being out there to be used by the account group as quickly because the account is provisioned.
After the structure has been arrange, account admins will see the AWS Service Catalog portfolios and ML workload account after they log in. The portfolios are prepared to make use of and may get the group up to the mark shortly.
Community structure
In our ML platform, we’re contemplating two totally different main logical environments for our workloads: manufacturing and pre-production environments with company connectivity, and sandbox or improvement iteration accounts with out company connectivity. These two environments can have totally different permissions and necessities in terms of connectivity.
As your atmosphere in AWS scales up, inter-VPC connectivity and on-premises VPC connectivity might want to scale in parallel. By utilizing companies similar to Amazon Digital Personal Cloud (Amazon VPC) and AWS Transit Gateway, you possibly can create a scalable community structure that’s extremely out there, safe, and compliant along with your firm’s finest practices. You may connect every account to its corresponding community section.
For simplicity, we create a transit gateway inside the central community account for our manufacturing workloads; this may resemble a manufacturing community section. It will create a hub and spoke VPC structure that can permit our manufacturing accounts to do the next:
- Allow inter-VPC communication between the totally different accounts.
- Examine site visitors with centralized egress or ingress to the community section.
- Present the environments with connectivity to on-premises information shops.
- Create a centralized VPC endpoints structure to scale back networking prices whereas sustaining personal community compliance. For extra particulars, see Centralized entry to VPC personal endpoints.
For extra details about these sort of architectures, consult with Constructing a Scalable and Safe Multi-VPC AWS Community Infrastructure.
The next diagram illustrates the really useful structure for deploying your transit gateways and creating attachments to the VPCs inside your accounts. Something thought of a manufacturing atmosphere, whether or not it’s a workload or shared companies account, is linked to the company community, whereas dev accounts have direct web connectivity to hurry up improvement and exploring of recent options.
At a excessive degree, this structure permits you to create totally different transit gateways inside your community account to your desired AWS Areas or environments. Scalability is offered via the account merchandising performance of AWS Management Tower, which deploys a CloudFormation stack to the accounts containing a VPC and the required infrastructure to hook up with the atmosphere’s corresponding community section. For extra details about this strategy, see the AWS Management Tower Information for Extending Your Touchdown Zone.
With this strategy, at any time when a group wants a brand new account, the platform group simply must know whether or not this will probably be an account with company community connectivity or not. Then the corresponding blueprint is chosen to bootstrap the account with, and the account is created. If it’s a company community account, the VPC will include an attachment to the manufacturing transit gateway.
Conclusion
On this submit, we mentioned finest practices for making a multi-account basis to help your analytics and ML workloads and configuring controls that will help you implement governance early in your ML lifecycle. We offered a baseline advice for OUs and accounts you need to think about creating utilizing AWS Management Tower and blueprints.
