In recent years, the need to construct end-to-end digital experiences has become increasingly important. But to deliver new features and services promptly, organizations must double down on agility and reusability. As part of this trend, applications have become increasingly modular, often constructed using pre-built microservices and integrating common SaaS to avoid reinventing the wheel.
MACH is an architectural style that fits into these trends quite well. It stands for Microservices-based, API-first, Cloud-native, and Headless. The locus of the movement is The Mach Alliance, a group of API-first companies abiding by these principles. At the time of writing, MACH is gaining mindshare as more API-first companies enter the market and the appetite for cloud-native technology grows.
I recently chatted with Gary Ballabio, VP of technology partnerships, Cloudinary, about the ongoing MACH trend. According to Ballabio, MACH delivers “best of breed” technologies that avoid the bloat of larger platforms. Yet, for software consumers, building in a MACH style will require stitching together individual components and orchestrating them effectively. Below, we’ll explore MACH and consider the benefits and drawbacks of utilizing tools that conform to this approach.
What Is MACH?
MACH is an emerging software architecture style adopted by a number of commerce and digital experience tools. To understand MACH a bit deeper, it’s necessary to understand the underlying concepts of microservices, API-first, cloud-native and headless. So, let’s first break apart these familiar terms:
- Microservices: Unlike monolithic development, a microservices architecture organizes functionality into self-contained, specialized components. This improves reusability and allows for more frequent, targeted software updates.
- API-first: API-first takes design-first one step further. It means putting the consumption model, the API, ahead of other concerns, like the application or UI. Web APIs have become ubiquitous for connecting a microservices ecosystem and exposing data and functionality to partners and public consumers.
- Cloud-native: An umbrella term for projects purpose-built for the elasticity and scalability of the cloud.
- Headless: Headless means separating the front end, or “head,” from the back end. By decoupling development this way, websites and apps are better equipped to cater to multiple platforms and devices.
According to Ballabio, companies can leverage cloud-ready best-of-breed functionality by integrating tools that adopt MACH principles. Incorporating one single SaaS to fit a specialized need can also be considered an alternative to using large, comprehensive enterprise commerce suites like Salesforce, Adobe or SAP, said Ballabio.
There are many examples of specialized SaaS services built in the MACH style. Some include Algolia for search and recommendations, Cloudinary for media management, Builder.io for mobile experiences, or Contentstack as a headless CMS. All these tools are members of The MACH Alliance, a group of over 70 vendors, partners, startups, systems integrators and other ambassadors dedicated to fostering the MACH approach. And although the emphasis has been on commerce and digital experiences, MACH is expanding beyond that scope to other areas.
MACH technologies support a composable enterprise in which every component is pluggable, scalable, replaceable.
Some readers may wonder, “How is this different than Jamstack (JavaScript, APIs and markdown)? In a way, MACH is similar to Jamstack, as both approaches aim for headless frontend experiences and a modular backend powered by APIs. But a key difference, said Ballabio, is that MACH doesn’t dictate the use of specific programming languages.
Benefits and Drawbacks of MACH
MACH combines many development trends we’re seeing in the software landscape. Digital applications are becoming more composable, cloud-first is rising, and headless models can deliver customization benefits. Yet, there are some potential drawbacks to introducing this style too. So, let’s weigh some of the positives and negatives of adopting MACH architecture.
Benefits
- Flexibility: The most significant benefit of MACH is the flexibility it offers, said Ballabio. “There’s value in being able to choose the services you want to use based on your own unique requirements.” Looping in a specific API-first tool for something like e-commerce, payments, CMS or email can enable a lot of customization.
- Reduced waste: This can create less waste, too, as you create a leaner footprint by acquiring only what you need for each project, and freemium models enable consumers to pay for only what they use. This is helpful when you want a single component but don’t require the bells and whistles of a more holistic platform.
- Best-of-breed: Niche API-first products are focused on doing one thing really well, and this particular focus can improve quality and agility. It also releases engineers from being at the whim of an extensive product’s development life cycle.
- Developer-first: Lastly, most digital experiences share common functionalities that developers shouldn’t have to reinvent. MACH supports being developer-first, says Ballabio, which is an asset to companies investing in developer experience.
Drawbacks
- Increased maintenance: Consuming many third-party cloud services will inevitably bring new maintenance hurdles. These include tracking, monitoring and securing all integration points. It also requires responding to new version updates.
- Stitching together: Naturally, when you add a cloud-based abstraction layer to the services you consume, the onus is on the consumer to then to stitch them together to make components talk to one another.
- Startup costs: Due to the coordination between services, initial costs and engineering time could be more than implementing a holistic suite, admitted Ballabio. “But you get more long-term benefits,” he said.
- Assistance may be required: Those unaccustomed to microservices development and API integration may need help. This may require the support of systems integrators or middleware to orchestrate connections.
- Lack of standards: MACH is more of a general architecture rather than a standard specification. Thus, the precise technologies under the hood and the specific behaviors may differ from service to service.
Future of MACH
A recent MACH Alliance study found 79% of tech leaders plan to invest more in MACH technologies in the next year. Although the style has been primarily trending in Europe, Ballabio predicts the U.S. will soon pick it up. The MACH Alliance presents and advocates for an open and best-of-breed enterprise technology ecosystem.
Along with the rise of composable architecture, the MACH approach is gaining interest among cloud-native leaders who see the advantage of assembling applications using pre-fabricated building blocks. MACH is especially a good fit for greenfield development, where the slate is clean to integrate new technology.
MACH represents a new category of companies that are growing together. Ballabio remarks that he feels part of a movement, part of an industry—and, arguably, this movement can potentially disrupt larger commerce ecosystems.
But although MACH gives a name to a face, most techies still aren’t aware of the acronym. While the concept may, for now, live in the domain of vendor-speak, Ballabio foresees it becoming a more common parlance for consumers and end developers.
