What is a repository structure?

In the world of artifact management, a repository structure refers to how software artifacts—such as Docker images, Python packages, npm modules, and more—are organized, stored, and accessed. It defines how repositories are named, grouped, and managed, often aligning with how software development teams build, release, and consume software binaries across an organization.

Repository structure is a fundamental foundation of secure, efficient artifact management practices. Your goal is to create the right structure that meets the needs of your developers.

Cloudsmith has an intrinsically flexible approach to repositories. We don’t force you to have a separate repository for each format type, like most other artifact management systems do. This presents you with an opportunity to define a more meaningful structure for your repositories, and this means you have many more interesting options!

We see some common patterns among Cloudsmith users that fall into the following groups:

• Mono-repository
• Language-specific repositories
• Team/service-specific repositories
• Environment-specific repositories
• Hybrid repository approach

We’ll be covering each structure in greater detail in our upcoming blogs as part of our Repository Structure Best Practices series.

Why is repository structure important?

Now that we’ve identified the “what” behind repository structures, we can dig into the “why” a little bit.

We address repository structure at the beginning of our onboarding process for new customers. If you get the repo structure wrong, then over time, artifact repositories can become a ‘dumping ground’ for all manner of software artifacts. When platform engineering teams are migrating to Cloudsmith, we find that there’s often a newfound interest in organization and consolidation of software artifacts, in order to ‘do better next time’ than they were able to with their legacy solution.

Perhaps the number one question we get at this point is, “How do we balance software supply chain security best practices with a great developer experience?”

While there isn’t really one simple answer to this question, the good news is that the flexibility Cloudsmith offers in choosing the repository structure can help you to check both boxes – security AND productivity.

Key benefits of the right repository structure

• Impact on DevEx & Productivity

Choosing a clear, intuitive structure removes significant friction for developers. If they are able to easily locate the packages they need, pull the open-source dependencies for their builds in a central location, and integrate quickly with CI/CD pipelines, you’re winning as a platform team already.

Many enterprise customers of Cloudsmith leverage a dedicated repository for all ingress packages, where open-source dependencies are proxied and cached for developers and pipelines to begin accessing. This centralized repository makes it easy for developers to remember the direct path URL for pulling on their local machines and even easier for updating their CI/CD pipelines.

With our API and UI, a developer can quickly review what packages are within a specific repository. No digging through countless folders and subfolders to find what you’re looking for!

• Impact on Security & Compliance

You’ll want your developers to be able to pull dependencies, create repositories, and configure upstream sources easily. But you also want to ensure developers are working securely. Repository structure directly influences how platform teams will be able to configure repository access controls, set permissions, review vulnerabilities, and inspect audit trails for suspicious signals.

In Cloudsmith, platform teams can restrict repository access by designating only specific developer teams to have access to specific repositories. At the permissions level, you can set read/write/admin permissions for each repository. This allows for granular access control, self-serve ownership, multiformat flexibility, and better visibility into team-by-team usage.

• Impact on Observability & Auditability

Observability and auditability of packages within your artifact management environment are directly correlated to how fine-grained your repositories are structured. The more segmented you configure them (i.e., by specific team, application, or environment), the clearer an observability team is able to view when a package was pulled and by whom. On the contrary, if an organization just has “non-prod” and “prod” repositories with many different service accounts and users pulling packages, it might be more difficult to pin down a specific action or event.

• Impact on CI/CD Pipelines & Workflows

The right repository structure really impacts an organization’s CI/CD pipelines. When pipelines are tightly coupled to poorly structured repositories, the result can be pipeline failures due to ambiguous package resolution, security risks from pulling artifacts from the wrong stage, and even increased build times due to inefficiencies in caching.

Common repository structure challenges

• Scaling Multiple Teams & Projects

As your organization grows, what originally worked for your first few developers will often break at scale. Without a flexible, scalable repository structure, you will quickly become susceptible to artifact sprawl, naming collisions, and access control issues. Cloudsmith’s fully cloud-native architecture helps enterprise customers scale tremendously while also maintaining order and consistency across repositories.

• Managing Artifacts Across Multiple Formats

Your organization is building all kinds of software, with software development across many different language formats, development teams, and environments to consider. It helps to have an artifact management platform that can support multi-format repositories, flexible upstream configurations to open-source registries, and easy-to-use package tagging.

• Balancing Security With Developer Velocity

Tighter security controls and a lack of freedoms can oftentimes frustrate developers, while open policies may create security gaps. A well-thought-out repository structure strikes a balance by allowing autonomy with clear guardrails. This is part of the developer “golden path” that can be architected by a platform team.

How the right repository structure delivers business value

• Faster Software Delivery & Reduced Operational Overhead

When artifacts are easy to find, manage, and deploy, your development teams spend less time figuring out where their artifacts are and more time building great software. Reducing toil and time to market is critical for any business creating software.

• Improved Agility for New Development Teams

A well-structured repository architecture supports growth by paving the way for new teams – which may include contractors – to spin up new environments (repos, teams, service accounts, tokens, etc.) by enabling replication across teams. A clear, concise, repeatable structure that only requires a few API calls makes it easier to scale without worrying about the underlying infrastructure to support globally distributed teams.

• Reduced Risk With Better Visibility And Controls

Platform teams are tasked with enabling development teams to write software efficiently and securely. By having a well-defined repository structure that every development team can follow, platform teams can create clear access control policies, artifact retention policies, and user permissions. Having this visibility and control lowers the risk of shipping insecure or unverified software.
