From setting up an account to deploying the final product, there are several stages involved, each with its own complexities.

This blog post will discuss the different stages of developing cloud applications and will provide tips and best practices to navigate through the process, based on our experience. Whether you are an experienced practitioner or new to the field, we hope that this post will offer valuable insights and guidance to help you create effective and innovative medical device cloud software.


During the planning stage, it is important for the development team to identify project goals, requirements, potential roadblocks, and risks. This can be achieved through brainstorming sessions, stakeholder interviews, and other collaborative methods. The team should also create a timeline and budget for the project and involve stakeholders from different departments, such as engineering, management, and marketing, to ensure everyone is aligned on project deliverables and timelines.

At this stage, the team should also consider the software development methodology that will be used throughout the project. Popular options include Agile methodology, Scrum, and Kanban frameworks. It's important to choose a methodology and a framework that is well-suited to the specific needs of the project and the team.

Cloud Infrastructure selection and setup:

Choosing the right cloud infrastructure provider is crucial for project success. Popular providers include AWS, Azure, and GCP, each with their own strengths and weaknesses. Evaluate providers based on technical stack, team expertise, service offerings, cost, integrations with development tools, security and compliance service offerings, and support.

Here are some recommended initial basic setups:

  • Set up a root or organizational account to manage multiple accounts, which can be created for different stages of development, departments, and products to minimize risk in case of a security breach.
  • Add developers and enforce strong password requirements and multi-factor authentication. Conduct regular access reviews to ensure users only have access to necessary resources.
  • Provide each member access to only the services they need through role segregation and create groups for streamlined access management.
  • Set up a budget to track and monitor costs. Cloud providers offer email notifications when costs surpass the budget. Investigate and terminate unnecessary resources to reduce costs.

Design and Development Process:

When developing software for medical devices, a structured process must be followed to meet regulatory standards and ensure high-quality deliverables. In the design phase, documenting all features and involving stakeholders can help ensure adequacy. During development, these best practices should be followed:

  • Version Control System: Use Git to track changes, collaborate effectively, and avoid conflicts. Hosting services like GitHub and Bitbucket can be used to store codebase and manage access control.
  • Modular and Reusable Code: Writing independent and reusable components helps reduce complexity and improve scalability.
  • Automated Testing: Using unit tests and end-to-end tests integrated into the development process catches defects early and ensures regulatory compliance.
  • Updated Libraries: Use updated libraries to ensure the software uses the latest features, performance enhancements, and security patches.
  • Automated Deployments: Configure a CI/CD Pipeline to automate the build, testing, and deployment process. The pipeline should include unit tests, end-to-end tests, and security scans to provide early feedback.
  • Security Scanners: Use static and dynamic analysis tools to identify potential security vulnerabilities. The OWASP website lists several options for security scanners (paid and free).


Testing is an essential component of the software development life cycle in the context of medical device software development. The following are some of the best practices that can be implemented:

  • Testing incremental changes: Test each change made to the software by developers to catch issues early on and maintain a stable state.
  • Validation and Verification (V&V) testing: Conduct comprehensive functional and non-functional testing, including performance and security, before release to ensure high quality.
  • Acceptance testing: Deploy software to a staging environment and invite stakeholders and end-users to test workflows, identify bugs, anomalies, and UI/UX issues.
  • Sanity test: Perform a final test after production release to ensure the software behavior aligns with expected results and to minimize unexpected issues or defects.


Effective documentation is critical in the software development life cycle, particularly for medical software development, to ensure compliance with regulatory requirements and enhance product reliability. Proper documentation throughout the development process enables efficient maintenance, updates, and testing of the software. The following are some of the essential documents required:

  • Software Requirements Specification (SRS): Outlines software requirements, purpose, and scope.
  • Test Procedure Document: Outlines testing procedures to ensure compliance with SRS requirements.
  • Software Hazard Analysis: Identifies potential hazards and their mitigation.
  • Traceability Matrix: Tracks the relationship between SRS requirements and testing procedures.

For cybersecurity, the following documents may be necessary:

  • Cybersecurity Design Features: Outlines cybersecurity features and functionality.
  • Threat Model: Identifies potential cybersecurity threats and risks.
  • Software Bill of Materials: Lists all the different open source and third party software components used in building the software. It must also specify the version used, and the vulnerability analysis of the software.

Security and Compliance:

Developing medical software requires strict adherence to security and compliance requirements to protect sensitive patient information. Here are some measures that can be taken:

  • Encryption: Data must be secured in transit and at rest, using HTTPS with the latest SSL/TLS version for security in transit and encryption of data in storage for security at rest.
  • Intrusion Prevention and Detection Systems: An IPS can help prevent attacks by blocking malicious traffic, while an IDS can detect and alert administrators to potential attacks.
  • Firewalls: Configuring application and network-level firewalls can block malicious requests and minimize the risk of compromise. Security and Infrastructure Scanners can also scan resources against industry standards to improve the overall security posture.
  • Privacy laws: Compliance with HIPAA and GDPR regulations is crucial, and tools are available to assist with compliance efforts.

Monitoring and Alerting:

Continuous monitoring of the medical software is important to detect and respond to any issues that may arise. This includes monitoring the performance, availability, and security of the software. Some key aspects of monitoring and alerting are:

  • Performance monitoring: This involves monitoring the response times, throughput, and resource utilization of the software. This helps identify any performance bottlenecks or capacity issues that may affect the user experience.
  • Availability monitoring: This involves monitoring the uptime and availability of the software, as well as any underlying infrastructure components. This helps detect and respond to any downtime or service disruptions, which can have serious implications for patient safety and care.
  • Security monitoring: This involves monitoring for any security events or incidents, such as unauthorized access attempts or data breaches. This helps identify and respond to security threats in a timely manner, to minimize the impact on patient data and privacy.
  • Alerting: Alerts should be set up to notify relevant personnel in case of any issues or incidents. These alerts should be actionable and provide enough information to quickly diagnose and resolve the issue.

Cloud providers often offer various monitoring and alerting services that can be used to monitor the software and infrastructure. It's important to configure these services properly and set up appropriate thresholds to ensure timely and accurate alerts. Additionally, periodic reviews of the monitoring and alerting configurations should be conducted to ensure they remain effective over time.


Regular maintenance of cloud infrastructure is essential to ensure optimal performance, reliability, and security of software. Key areas to focus on include:

  • Security: Regularly scanning applications for vulnerabilities and third-party libraries to avoid potential compromises.
  • Reliability and Scalability: Periodic review of environment metrics to identify peak traffic and errors, ensuring the system can handle increased usage.
  • Cost Optimization: Monitoring usage patterns and adjusting reserved instance usage to reduce costs and improve efficiency.
  • Documentation: Maintaining up-to-date documentation of any changes made to the system, as well as regularly reviewing and updating documentation as necessary.
