Pulumi Consulting

Pulumi is an infrastructure-as-code (IaC) tool for defining, provisioning, and managing cloud resources using general-purpose languages such as TypeScript, Python, Go, and C#. It is commonly used by DevOps and platform engineering teams to standardize environments, reduce configuration drift, and apply familiar software engineering practices to infrastructure changes across AWS, Azure, Google Cloud, and Kubernetes.

Pulumi is typically integrated into CI/CD pipelines to preview changes in pull requests, promote updates across accounts or clusters, and package reusable components for consistent patterns. It often complements broader platform engineering efforts focused on guardrails and repeatable delivery.

• Define infrastructure with real programming constructs (modules, functions, packages)
• Preview and apply changes with managed state for safer updates
• Provision multi-cloud and Kubernetes resources through provider SDKs
• Create reusable components to standardize networking, IAM, and app stacks
• Support policy and compliance checks as part of deployments

• With Infrastructure as Code, you can gain an insight into your infrastructure status swiftly, as it serves as a living document offering a snapshot of your systems' state and configuration.
• Infrastructure as Code allows you to improve your infrastructure using code itself, making the process of introducing new services, upgrading existing ones, or modifying configurations flexible and adaptable.
• Infrastructure as Code facilitates making system-wide modifications efficiently, ensuring consistency across your entire system and reducing error potential.
• Continuous integration principles from software development can be applied to your infrastructure management through Infrastructure as Code, enabling automation in testing and deployment of infrastructure changes.
• Infrastructure as Code enables you to provision entire systems from scratch quickly and reliably, proving to be advantageous in testing, development, and disaster recovery scenarios.
• Monitoring infrastructure state and implementing incremental changes is made possible with Infrastructure as Code, improving auditability and change management.
• By automating repetitive tasks and reducing manual intervention, Infrastructure as Code reduces potential human errors and increases efficiency.
• Infrastructure as Code enhances collaboration and transparency by serving as a common language understandable by both operations and development teams.
• Infrastructure as Code allows for the creation of standard templates for your infrastructure setup that can be used to replicate your environments consistently across different stages of the application lifecycle and multiple projects.
• Infrastructure as Code improves overall security posture and simplifies compliance auditing by allowing the incorporation of security configurations and compliance requirements directly into your infrastructure code.

Pulumi is an infrastructure-as-code (IaC) tool for provisioning and managing cloud and Kubernetes resources using general-purpose programming languages. It is used when teams want to apply software engineering practices like reuse, testing, and CI/CD to infrastructure delivery.

• Uses TypeScript, Python, Go, and C#, which lets teams build infrastructure with familiar languages, IDE support, and package ecosystems.
• Supports real programming constructs such as functions, classes, and modules, which makes complex patterns easier to model and maintain than purely declarative templates.
• Enables reusable components and internal libraries, which helps platform teams standardize “golden path” infrastructure and reduce copy-paste across services.
• Provides previews and diffs before applying changes, which improves review quality and reduces unintended modifications during deployments.
• Integrates cleanly with Git-based workflows and CI/CD pipelines, which supports repeatable environment promotion and controlled rollouts.
• Offers broad provider coverage across AWS, Azure, GCP, and Kubernetes, which supports consistent provisioning in multi-cloud and hybrid setups.
• Includes encrypted configuration and secrets handling, which helps keep sensitive values out of source control and simplifies secure automation.
• Supports policy-as-code with CrossGuard, which can enforce security, cost, and compliance guardrails during preview and update operations.
• Works with multiple state backends including the Pulumi Service and self-managed storage, which helps meet governance, audit, and data residency needs.
• Supports unit and integration testing for infrastructure logic, which helps catch errors earlier and aligns infrastructure changes with standard engineering quality gates.

Pulumi is a strong fit for internal developer platforms, shared infrastructure modules, and organizations that want infrastructure delivery to follow the same engineering conventions as application code. Because infrastructure is expressed as code, teams typically need conventions for dependency management, provider version pinning, and state organization to keep deployments stable at scale.

For implementation details and best practices, refer to the Pulumi documentation. Common alternatives include Terraform, AWS CloudFormation, and Azure Bicep.

Our experience with Pulumi helped us treat infrastructure delivery like software engineering—using real programming languages, code review, and automated testing to create reusable, consistent infrastructure patterns that teams can safely evolve over time.

Some of the things we did include:

• Established Pulumi project/stack conventions (naming, config structure, secrets handling, and environment promotion) to support multi-account and multi-region deployments with fewer surprises.
• Migrated existing environments from legacy IaC and manually created resources into Pulumi using import workflows, state reconciliation, and staged cutovers with rollback plans.
• Built internal component libraries (TypeScript/Python/Go) for common building blocks like VPC/networking, IAM, Kubernetes clusters, databases, queues, and baseline observability to standardize delivery across teams.
• Integrated Pulumi into CI/CD with previews, approvals, and drift checks using GitHub Actions and GitLab, including safe promotion between dev/stage/prod.
• Provisioned Kubernetes platforms and add-ons with Pulumi, integrating with Kubernetes and Helm for repeatable bootstrap, upgrades, and add-on lifecycle management.
• Implemented policy-as-code guardrails (naming, tagging, encryption, network boundaries, and approved SKUs) using Pulumi CrossGuard to prevent insecure or noncompliant changes from reaching production.
• Hardened security posture by enforcing least-privilege IAM, consistent secret management, and standardized audit logging as part of provisioning rather than as a day-2 retrofit.
• Automated ephemeral environments for pull requests (create/preview/destroy) to speed up delivery while controlling cost and reducing orphaned resources.
• Implemented HA/DR patterns (multi-AZ design, backups, restore testing, and runbooks) so recovery objectives could be validated through repeatable Pulumi workflows.
• Enabled teams through workshops and pairing on component design, safe refactors, debugging previews, and operational ownership (alerts, runbooks, and on-call readiness).

This delivery experience helped us accumulate significant knowledge across migrations, platform builds, and day-2 operations, and it enables us to deliver high-quality Pulumi setups that are maintainable, secure, and aligned with how engineering teams ship software.

Some of the things we can help you do with Pulumi include:

• Assess your current infrastructure-as-code posture and deliver a prioritized report covering reliability, security, and maintainability gaps.
• Define a Pulumi adoption roadmap (language choice, project/stack structure, environments, and workflows) aligned to delivery and governance needs.
• Implement Pulumi programs end-to-end, including stack configuration, state management, secrets handling, and repeatable environment provisioning.
• Migrate from legacy scripts or other IaC tools into Pulumi with clear cutover plans, validation steps, and minimal downtime.
• Build CI/CD automation for infrastructure changes (previews, policy checks, approvals, and promotions) using Git-based workflows.
• Establish security and compliance guardrails with policy-as-code, least-privilege IAM patterns, and secure secret management.
• Optimize cloud cost and performance by standardizing tagging, budgets, resource sizing, and safe rollout patterns across environments.
• Improve operational reliability with observability-friendly infrastructure patterns, drift detection/response practices, and actionable runbooks.
• Enable teams with hands-on training, pairing, and reference templates so developers can ship infrastructure confidently in TypeScript, Python, Go, or C#.
