by John Browne, on Jul 18, 2023 5:00:31 PM


As far as I can tell, there are only two things that are easy to do in the cloud: paying too much and getting it wrong.

That's where reference architecture comes in.

What's a reference architecture?

A reference architecture is an opinionated, end-to-end tech stack built on top of the Infrastructure as Code Library that deployed into your AWS, Azure or Snowflake. The reference architecture provides IT best practices, common language, and templates in an easy-to-understand format that guides implementation.

Why is reference architecture important?

When it comes to cloud migration, having a well-defined tech stack is crucial. You want correctness, performance, and efficiency. You want enough, but not too much. But building the perfect tech stack from scratch can be time-consuming and error-prone. That's where a reference architecture comes in.

The sheer number of services, options, and choices one has to make to set up a rich cloud-based system reminds me of the saying by Ken Schramm that a smart person learns from their mistakes, while a wise person learns from the mistakes of others. 

A reference architecture provides you with an opinionated, battle-tested, end-to-end tech stack that is ready to deploy into your cloud environment. It takes the guesswork out of setting up your cloud infrastructure and allows you to focus on what really matters – your applications and services. 

By leveraging the Infrastructure as Code (IaC) Library, you can quickly and easily set up the foundation of your cloud infrastructure. The IaC Library is a collection of pre-built templates and scripts that allow you to define your infrastructure as code. This means that you can version control your infrastructure, apply changes in a consistent and repeatable manner, and easily collaborate with your team.

With the reference architecture, you don't have to worry about making the wrong choices or missing critical components. It offers a proven blueprint that covers everything from networking and security to compute and storage.

  • When it comes to networking, the reference architecture includes best practices for setting up virtual private clouds (VPCs), subnets, and routing. It also provides guidance on implementing security measures such as network access control lists (ACLs) and security groups to protect your resources.
  • For compute, the reference architecture offers recommendations on choosing the right instance types and sizes for your workloads. It also includes guidelines on auto scaling to ensure that your applications can handle varying levels of traffic and demand.
  • When it comes to storage, the reference architecture covers options such as Amazon S3 for object storage, Amazon EBS for block storage, and Amazon Glacier for long-term archival storage. It also provides guidance on data backup and disaster recovery strategies to ensure the availability and durability of your data.

By following the reference architecture's guidelines, you can ensure that your cloud adoption is on the right track and avoid costly mistakes. It provides a solid foundation for your cloud infrastructure and allows you to focus on developing and delivering your applications and services.

A reference architecture builds a strong foundation 

No building can be stronger than its foundation. Same is true for your migration to a cloud deployment: get the foundation right and the rest will follow. The reference architecture provides a best-practices approach to setting up all the foundational components necessary for a successful transition to the cloud. Drawing from years of experience, lessons learned, and industry standards (read: mistakes of others), this comprehensive framework ensures that your cloud infrastructure is built on a bedrock of excellence.

By embracing the reference architecture, you can streamline the process of designing and implementing your cloud infrastructure. Acting as a trusted guide, it provides a roadmap that outlines the necessary steps and best practices to follow. From network design to security configurations, the reference architecture covers all aspects of setting up your cloud environment, leaving no stone unturned.

Let's delve deeper into the key elements encompassed within the reference architecture:

Network design

An essential aspect of any cloud infrastructure is its network design. The reference architecture offers a comprehensive blueprint for creating a robust and scalable network that meets your organization's unique requirements. It takes into account factors such as network segmentation, load balancing, and high availability, ensuring that your cloud environment operates seamlessly and efficiently.

Furthermore, the reference architecture provides guidance on implementing advanced networking features, such as virtual private clouds (VPCs), subnets, and routing tables. By following these recommendations, you can optimize network performance, enhance security, and achieve optimal resource utilization within your cloud environment.


Security is of paramount importance when migrating to the cloud. The reference architecture incorporates industry-leading security practices to help you fortify your cloud infrastructure against potential threats. It provides detailed guidelines for implementing robust access controls, encryption mechanisms, and identity and access management (IAM) policies.

Moreover, the reference architecture emphasizes the importance of continuous monitoring and auditing to ensure compliance and detect any potential vulnerabilities. It outlines the integration of security services such as firewalls, intrusion detection systems, and security information and event management (SIEM) tools, enabling you to establish a comprehensive security posture within your cloud environment


One of the key advantages of the cloud is its ability to scale resources on-demand. The reference architecture offers insights into designing a scalable and elastic infrastructure that can dynamically adapt to fluctuating workloads. It provides recommendations for leveraging auto-scaling groups, load balancers, and serverless computing to optimize resource allocation and ensure high availability.

By following the reference architecture's guidance on scalability and elasticity, you can effectively manage peak traffic loads, minimize costs during periods of low demand, and deliver a seamless user experience to your customers.

Data management

Efficient data management is critical for organizations operating in the cloud. The reference architecture outlines best practices for data storage, backup, and recovery, ensuring the integrity and availability of your valuable information. It covers topics such as data encryption, data lifecycle management, and disaster recovery strategies.

Additionally, the reference architecture provides guidance on leveraging cloud-native databases, data warehouses, and data lakes to unlock the full potential of your data. By implementing these recommendations, you can harness the power of advanced analytics, machine learning, and artificial intelligence to derive valuable insights and drive informed decision-making.

The benefits of a reference architecture for cloud infrastructure

Adopting cloud technologies can be a daunting task, especially if you don't have prior experience. That's where the reference architecture comes in handy. It provides numerous benefits that can help simplify and accelerate your cloud adoption journey.

Some of the key benefits of a reference architecture include:
