DevOps for Epic, Cerner, and Custom EHR: A CIO’s Guide to Continuous Delivery in Regulated Environments
Despite modern hospitals’ increased demands for faster and more reliable custom EHR upgrades, healthcare IT remains tightly managed. Medical-device software rules (FDA 21 CFR Part 820) and legislation governing patient data protection and clinical safety (HIPAA, HITECH) impose stringent documentation, traceability, and security requirements. For example, the FDA regulates software that qualifies as a medical device, and EHR software that handles protected health information (PHI) must follow HIPAA’s encryption and access restrictions.
These frameworks mandate change control, process validation, and audit trails. In this environment, deploying DevOps (and DevSecOps) necessitates balancing the speed of continuous delivery with the thorough, documented change management demanded by regulators. It is critical to plan controls early on, such as versioning each change, encrypting data in transit or storage, and adding compliance checks into CI/CD pipelines.
Regulatory and Compliance Challenges in Healthcare IT
Healthcare DevOps faces unique hurdles. Any pipeline step that touches data or systems can expose PHI, so strict access control and encryption throughout are mandatory.
- Every code modification needs to be inspected and traceable. Epic’s Build Wizard, for example, keeps track of changes made to build recommendations, and Cerner and Epic keep detailed audit logs and version histories of configuration upgrades and revisions.
- To uncover vulnerabilities early on, pipelines must incorporate compliance gates such as security testing, dependency scanning, and static code analysis.
- To protect containers and cloud architecture, choose compliant cloud services (AWS, Azure, and GCP all provide HIPAA-compliant alternatives with Business Associate Agreements) and configure Kubernetes or virtual machines (VMs) in accordance with industry standards.
- Robust logging (such as AWS CloudTrail, Azure Monitor, and GCP Audit Logs) is critical for detecting unwanted access.
Governance must be included in DevOps in the healthcare sector. Teams must enforce encryption, MFA, RBAC, and regular security reviews at all levels, and each repository commit, infrastructure change (IaC), or build artifact must generate an audit trail.
Continuous Integration/Delivery with Compliance Controls
To introduce CI/CD while maintaining compliance, teams should shift compliance left. Integrate HIPAA and security checks into build pipelines so that “only code that meets requirements goes into production”. For example, automated CI processes can do static application security testing (SAST) on code, software composition analysis (SCA) on libraries, and vulnerability scanning on container images. Dynamic testing (DAST or API fuzzing) can be run in a sandbox or staging environment.
All builds should produce a Software Bill of Materials (SBOM) and a compliance report for audit purposes. Data-driven checks can function as code-quality gates, such as confirming encryption settings and API access scopes. To ensure that environments are consistently provided and auditable, pipelines should also enforce infrastructure as code (IaC). Tools like Terraform or CloudFormation let teams snapshot “known-good” infrastructure states; daily snapshots and infrastructure backups allow quick rollbacks.
Crucially, continuous monitoring alerts (integrated with SIEMs) and audit logs must be generated automatically for each deployment. These controls ensure that the pipeline itself builds in the documentation, testing, and approvals regulators require (for instance, automated test results and deployment logs can serve as evidence of validation).
Epic and Cerner Release Cycles vs. Custom EHR
Commercial EHR vendors have their own upgrade cadences.
- Epic now follows a strict quarterly release schedule (major versions in February, May, August, November) plus Special Updates for urgent fixes.
- Cerner likewise pushes frequent updates, categorized as Major, Minor, and Incremental releases.
- Hospitals on these platforms must plan upgrades and feature rollouts accordingly.
For Epic and Cerner, most DevOps efforts are not custom code but configuration, report builds, and workflow changes that are packaged and tested against each new base release.
Both systems provide tools to compare and log changes — Epic’s Build Wizard, for example, suggests build changes per release and keeps an audit history of all applied configuration updates. Nonetheless, true code-level version control (Git, etc.) is typically used only for custom modules, integration scripts, or middleware connecting to these EHRs.
Custom-built EHR platforms, by contrast, can embrace modern DevOps end-to-end. A proprietary or open-source EHR allows developers to store all source code and infrastructure definitions in version control, enabling full CI/CD on application code. Continuous delivery for custom EHRs can use feature toggles and microservices architectures to isolate changes. For example:
Epic (Vendor EHR)
Quarterly major releases with vendor-managed code base; internal teams focus on configuration and validation of new features. Version control is limited to in-house scripts or API clients.
Cerner (Vendor EHR)
Ongoing incremental releases; integration testing with SMART-on-FHIR or HL7 interfaces in the sandbox. Change logs and reporting tools capture configuration changes (though code changes to Cerner products are generally vendor-delivered).

Custom EHR
Team-owned code and services; full agility. Developers can break the system into microservices or modules, each with its own CI pipeline. They can use blue/green deployments, feature flags, or canary rolls for production updates without waiting on a vendor schedule.
To manage releases, DevOps teams should implement strict version control and branching strategies even for configurations. Any bespoke scripts, interfaces, or UI forms should be kept in Git (or similar), and automated build jobs should generate deployable packages. Change-management policies must still apply: each branch and release candidate should have test approvals and traceability back to user stories or regulatory documents.
As an example of tooling support, Epic’s newer automation features (Kuiper, ORBIT, etc.) help streamline builds, and Cerner’s dev tools allow scripted deployment of FHIR apps in a sandbox. Custom EHRs can fully leverage CI tools like Jenkins/GitLab CI/Azure DevOps, container registries, and infrastructure pipelines to autonomously push updates through test and approval stages.

Technical Stack and Tooling for Regulated CI/CD
Security and compliance are critical components of a healthcare DevOps toolchain. Microservices and containers are popular architectural trends that complement CI/CD. It is simpler to create, test, and implement components independently when an EHR is divided into loosely connected services.
Microservices can be packaged into Docker images for controlled deployment and are naturally tested in isolation. In contrast, automated testing and agility are hampered by conventional monolithic integrations, such as enterprise service buses. These services are then operated in secure clusters (on-premises or in a cloud that complies with HIPAA regulations) using Kubernetes or other orchestration tools.
Key stack elements include:
Containers & Orchestration
- Docker/Kubernetes to isolate services and enable canary or blue-green deployments, which enable an instant rollback to a prior environment in the event of an issue.
- Red Hat OpenShift and AWS EKS are examples of tools with stringent policy restrictions (PodSecurityPolicies, NetworkPolicies) that can limit communications between services and enforce encryption-in-transit.
- Every image build should include a container vulnerability scanner.
CI/CD Platforms
- Builds and tests can be automated with Jenkins, GitLab CI/CD, Azure DevOps, or GitHub Actions pipelines.
- These ought to incorporate security plugins (like SAST and SCA).
- They also oversee permission gates. For instance, before merging to master, a modification to an Epic configuration export or FHIR interface code would need to be reviewed and approved.
Infrastructure as Code (IaC)
- Tools for configuring servers, networks, and databases include Terraform and Ansible. IaC guarantees the versioning and repeatability of infrastructure modifications (such as installing a database fix or setting up a new test server).
- IaC definitions go through code review and testing since they are code.
- By mapping infrastructure in Terraform and taking frequent snapshots, teams can restore environments swiftly.
Automation & Configuration Management
- Configuring application settings, deploying code, and enforcing security baselines (such as firewall rules and file permissions) are all possible with Ansible, Chef, or Puppet.
- In audits, automation is essential since it minimizes human drift.
Logging and Monitoring
- Every operation, including code deployments, configuration changes, and user access, is recorded via centralised logging (ELK Stack, Splunk, or cloud log services).
- System health and compliance are tracked by metrics and alarms (Prometheus, Grafana) (e.g. checking encryption or login attempts).
- Teams can identify problems early and continuously record the system’s condition thanks to observability.
Security Tools
- Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) tools should be embedded in builds.
- Container images and code libraries should be scanned for CVEs and misconfigurations.
- Secrets management (Vault, AWS Secrets Manager) ensures no credentials leak into code.
- Regular dependency checks (Software Composition Analysis) prevent unvetted libraries.
Healthcare companies can build an agile, compliant pipeline by adopting a stack grounded in these principles: cloud or on-premises environments with HIPAA-aligned controls, microservices for modularity, IaC for consistency, and automated security solutions at every level.
Generally speaking, any tool or service used (from cloud providers to third-party libraries) needs to be verified for HIPAA/ISO 27001 compliance and, if required, covered by a Business Associate Agreement.
Integration Testing, Sandboxes, and Validation
Because live patient data is sensitive, integration testing in healthcare devops relies on isolated environments and synthetic data. Vendor EHRs provide dedicated test instances:
- Epic offers a single FHIR Developer Sandbox that is refreshed weekly and updated quarterly to the latest release.
- This sandbox simulates a full EHR with sample (non-PHI) data, enabling automated tests of FHIR APIs, SMART apps, and HL7 interfaces without risk.
- Cerner similarly provides a SMART-on-FHIR sandbox in its developer portal for building and testing apps.
- This sandbox allows for risk-free automated testing of FHIR APIs, SMART apps, and HL7 interfaces by simulating a complete EHR with sample (non-PHI) data.
In a similar vein, Cerner’s developer portal offers a SMART-on-FHIR sandbox for creating and testing applications.. These vendor sandboxes allow continuous integration suites to validate their code against realistic EHR systems. Within each hospital’s own environment, typical life-cycle systems (DEV, TEST, UAT, PROD) are maintained. Integration tests should run in DEV/TEST on synthetic or scrubbed data (never real PHI). Best practice is to generate comprehensive test datasets that cover normal and edge-case clinical scenarios while ensuring anonymity.
Automated tests then verify end-to-end workflows: e.g. admit-discharge transfers, lab order placement, and result reporting across EHR and interfaced systems. New code or configuration changes trigger these tests in CI; any failures block promotion. Continuous validation tools (API contract tests, HL7 message validators, FHIR conformance tests) ensure data integrity and adherence to standards.
To summarize, healthcare DevOps requires “safety glass” between live data and testing. Use vendor sandboxes and internal testing environments populated with only synthetic or masked data. Automate as much validation as possible. For example, include integration test stages in the pipeline that verify interactions with the EHR (login, query patient records, write orders, etc.) using service accounts with limited scopes. This ensures releases are safe and functionally correct before touching production.
Change Management and Rollback Strategies
Even with automation, mission-critical systems like EHRs demand rigorous change control. Any deployment path must include staged approvals and potential rollback plans. Multidisciplinary governance committees (including clinicians, compliance officers, and IT leads) should review major changes or new feature flag activations. Documentation and audit trails are key: every change request, approval, and test result should be logged in change management systems. Teams should treat rollback procedures as part of development: blue-green or canary release patterns allow immediate cutoff of a bad release, and feature toggles let you disable new functionality without redeploying code.
For rollback specifically, maintain full backups and environment snapshots so you can revert to a “known good” state quickly. In containerized deployments, this might mean re-pointing load balancers to the previous version; in server-based deployments, restoring from backup. Write and test rollback runbooks: who does what, and how. As industry guidance notes, having reliable rollback procedures “protects against costly failures”. Automate wherever possible: for example, keep historical builds so a previous artifact can be re-deployed by script. Monitor post-deployment health indicators closely (response times, error rates, intrusion alerts) so anomalies trigger immediate failover actions.
User training and communication are also change controls. Because updates may alter clinician workflows, ensure training materials are updated in tandem and that a rapid support channel is ready after go-live. In all cases, schedule changes during low-demand windows and have emergency plans for extended downtime. In highly regulated healthcare, it’s better to move cautiously with a robust rollback option than to rush and risk patient impact.
