MACH Architecture: What It Is & Why You (Might) Need It

There’s a new acronym on the block: MACH (pronounced “mock”) architecture. 

But like X is to Twitter, MACH is more a rebrand than a reinvention. In fact, you’re probably already familiar with the M, A, C, and H and may even use them across your digital properties. While we’ve been helping our clients implement aspects of MACH architecture for years, organizations like the MACH Alliance have recently formed in an attempt to provide clearer definition around the approach, as well as to align their service offerings with the technologies at hand. 

One thing we’ve learned at Oomph after years of working with these technologies? It isn’t an all-or-nothing proposition. There are many degrees of MACH adoption, and how far you go depends on your organization and its unique needs. 

But first, you need to know what MACH architecture is, why it’s great (and when it’s not), and how to get started. 

What Is MACH?

MACH is an approach to designing, building, and testing agile digital systems — particularly websites. It stands for microservices, APIs, cloud-native, and headless. 

Like a composable business, MACH unites a few tried-and-true components into a single, seamless framework for building modern digital systems. 

The components of MACH architecture are: 

1. Microservices: Many online features and functions can be separated into more specific tasks, or microservices. Modern web apps often rely on specialized vendors to offer individual services, like sending emails, authenticating users, or completing transactions, rather than a single provider to rule them all. 
2. APIs: Microservices interact with a website through APIs, or application programming interfaces. This allows developers to change the site’s architecture without impacting the applications that use APIs and easily offer those APIs to their customers.
3. Cloud-Native: A cloud-based environment hosts websites and applications via the Internet, ensuring scalability and performance. Modern cloud technology like Kubernetes, containers, and virtual machines keep applications consistent while meeting the demands of your users. 
4. Headless: Modern Javascript frameworks like Next.js and Gatsby empower intuitive front ends that can be coupled with a variety of back-end content management systems, like Drupal and WordPress. This gives administrators the authoring power they want without impacting end users’ experience. 

Are You Already MACHing? 

Even if the term MACH is new to you, chances are good that you’re already doing some version of it. Here are some telltale signs:

• You have one vendor for single sign-on (SSO), one vendor to capture payment information, another to handle email payment confirmations, and so on. 
• You use APIs to integrate with tech solutions like Hubspot, Salesforce, PayPal, and more. 
• Your website — or any website feature or application — is deployed within a cloud environment. 
• Your website’s front end is managed by a different vendor than its back end. 

If you’re doing any of the above, you’re MACHing. But the magic of MACH is in bringing them all together, and there are plenty of reasons why companies are taking the leap. 

5 Benefits of MACH Architecture

If you make the transition to MACH, you can expect: 

1. Choice: Organizations that use MACH don’t have to settle for one provider that’s “good enough” for the countless services websites need. Instead, they can choose the best vendor for the job. For example, when Oomph worked with One Percent for America to build a platform offering low-interest loans to immigrants pursuing citizenship, that meant leveraging the Salesforce CRM for loan approvals, while choosing “Click and Pledge” for donations and credit card transactions. 
2. Flexibility: MACH architecture’s modular nature allows you to select and integrate individual components more easily and seamlessly update or replace those components.  Our client Leica, for example, was able to update its order fulfillment application with minimal impact to the rest of its Drupal site. 
3. Performance: Headless applications often run faster and are easier to test, so you can deploy knowing you’ve created an optimal user experience. For example, we used a decoupled architecture for our client Wingspans to create a stable, flexible, and scalable site with lightning-fast performance for its audience of young career-seekers.     
4. Security: Breaches are generally limited to individual features or components, keeping your entire system more secure. 
5. Future-Proofing: A MACH system scales easily because each service is individually configured, making it easier to keep up with technologies and trends and avoid becoming out-of-date. 

5 Drawbacks of MACH Architecture

As beneficial as MACH architecture can be, making the switch isn’t always smooth sailing. Before deciding to adopt MACH, consider these potential pitfalls. 

1. Complexity: With MACH architecture, you’ll have more vendors — sometimes a lot more — than if you run everything on one enterprise system. That’s more relationships to manage and more training needed for your employees, which can complicate development, testing, deployment, and overall system understanding. 
2. Challenges With Data Parity: Following data and transactions across multiple microservices can be tricky. You may encounter synchronization issues as you get your system dialed in, which can frustrate your customers and the team maintaining your website. 
3. Security: You read that right — security is a potential pro and a con with MACH, depending on your risk tolerance. While your whole site is less likely to go down with MACH, working with more vendors leaves you more vulnerable to breaches for specific services. 
4. Technological Mishaps: As you explore new solutions for specific services, you’ll often start to use newer and less proven technologies. While some solutions will be a home run, you may also have a few misses. 
5. Complicated Pricing: Instead of paying one price tag for an enterprise system, MACH means buying multiple subscriptions that can fluctuate more in price. This, coupled with the increased overhead of operating a MACH-based website, can burden your budget. 

Is MACH Architecture Right for You? 

In our experience, most brands could benefit from at least a little bit of MACH. Some of our clients are taking a MACH-lite approach with a few services or apps, while others have adopted a more comprehensive MACH architecture. 

Whether MACH is the right move for you depends on your: 

1. Platform Size and Complexity: Smaller brands with tight budgets and simple websites may not need a full-on MACH approach. But if you’re managing content across multiple sites and apps, managing a high volume of communications and transactions, and need to iterate quickly to keep up with rapid growth, MACH is often the way to go. 
2. Level of Security: If you’re in a highly regulated industry and need things locked down, you may be better off with a single enterprise system than a multi-vendor MACH solution.  
3. ROI Needs: If it’s time to replace your system anyway, or you’re struggling with internal costs and the diminishing value of your current setup, it may be time to consider MACH. 
4. Organizational Structure: If different teams are responsible for distinct business functions, MACH may be a good fit. 

How To Implement MACH Architecture

If any of the above scenarios apply to your organization, you’re probably anxious to give MACH a go. But a solid MACH architecture doesn’t happen overnight. We recommend starting with a technology audit: a systematic, data-driven review of your current system and its limitations.

We recently partnered with career platform Wingspans to modernize its website. Below is an example of the audit and the output: a seamless and responsive MACH architecture. 

The Audit

1. Surveys/Questionnaires: We started with some simple questions about Wingspan’s website, including what was working, what wasn’t, and the team’s reasons for updating. They shared that they wanted to offer their users a more modern experience. 
2. Stakeholder Interviews: We used insights from the surveys to spark more in-depth discussions with team members close to the website. Through conversation, we uncovered that website performance and speed were their users’ primary pain points. 
3. Systems Access and Audit: Then, we took a peek under the hood. Wingspans had already shared its poor experiences with previous vendors and applications, so we wanted to uncover simpler ways to improve site speed and performance. 
4. Organizational Structure: Understanding how the organization functions helps design a system to meet those needs. The Wingspans team was excited about modern technology and relatively savvy, but they also needed a system that could accommodate thousands of authenticated community members. 
5. Marketing Plan Review: We also wanted to understand how Wingspans would talk about their website. They sought an “app-like” experience with super-fast search, which gave us insight into how their MACH system needed to function. 
6. Roadmap: Wingspans had a rapid go-to-market timeline. We simplified our typical roadmap to meet that goal, knowing that MACH architecture would be easy to update down the road. 
7. Delivery: We recommended Wingspans deploy as a headless site (a site we later developed for them), with documentation we could hand off to their design partner. 

The Output 

We later deployed Wingspans.com as a headless site using the following components of MACH architecture:

1. Microservices: Wingspans leverages microservices like Algolia Search for site search, Amazon AWS for email sends and static site hosting, and Stripe for managing transactions.
2. APIs: Wingspans.com communicates with the above microservices through simple APIs. 
3. Cloud-Native: The new website uses cloud-computing services like Google Firebase, which supports user authentication and data storage. 
4. Headless: Gatsby powers the front-end design, while Cosmic JS is the back-end content management system (CMS).
