JAMstack + Serverless = The right path

Iñaki BarturenJuly 27, 2021

JAMstack is a development methodology that helps fulfill a platform-wide purpose: To move fast and be light.

The development using static sites in no case means that applications lose speed; on the contrary, thanks to webhooks and microservices executed through serverless infrastructure, platforms gain speed, dynamism, and above all, quality of service.

What does it mean to "be" serverless?

Serverless or without a server is an execution model in which the cloud provider (AWS, Azure, or Google Cloud, as examples) is responsible for executing a piece of code by the dynamic allocation of resources, only charging for the amount used to run the code.

  • Programs (or functions thereof) operate in stateless containers, which can be triggered by a variety of events, including HTTP requests, database events, queued services, monitoring alerts, file uploads, and scheduled jobs (cron-jobs), among others.
  • The provider for execution is usually in the form of a function. Therefore, serverless technology is sometimes referred to as "Functions as a Service" or "FaaS".

Why is serverless the right path when we talk about JAMstack?

JAMStack is a way of developing modern architecture based on JavaScript from the client-side and uses API calls to execute the various events that make up a platform that specialized external companies provide.

  • The core element is the static content, which combines markup with templates to create HTML that can be cached and distributed by CDN at high speeds and without conditioning any of the other components of the platform.
  • Thus, a Static Site Generator is deployed, and a headless CMS is linked, where all the content is managed. The backend then focuses on the internal operation of the business. At the same time, the frontend remains available for all the rest of the functions such as search engines, shopping carts, or payment systems that are included as external microservices waiting to be activated as events or functions; in summary, serverless.

Main benefits of using a serverless structure

The difference between conventional and serverless development may not be significant for small platforms or eCommerce stores. However, when it comes to a larger company or platform with thousands of pages, products, a large number of concurrent users, and multiple channels, the differences are undeniable, and the benefits stand out.

1. Security for your platform

If we look at it from the organizational side, the first thing that stands out is the security of the entire platform. By having external microservices, each provider is responsible for its infrastructure and the resources required for security and operation. Thus, you don't need to worry about database vulnerability or denial of service attacks on your server.

2. High performance

Another aspect is performance: since these providers are specialized in each element of the platform, you will not need your team of developers to worry about execution times, latency, and call efficiency. Each provider will ensure - with great dedication - the performance of their services, which - combined - will take your platform to a global category.

3. Cost certainty

In addition to the above, you will have a better projection of the cost of your business, since on the one hand displaying static content is much cheaper, but on the other, microservices will have specific terms and costs. You will only pay for activated events at the subscribed price.

4. A better digital experience

Seen from the end-user or client-side of our business, using microservices running fractions of code in the cloud (as events upon requirement) results in a quick response in an infrastructure that is specialized for this purpose.

An example is to include Algolia, which allows doing predictive searches, returning results on the fly from the first character entered, providing a fast and intelligent experience, regardless of bandwidth or device.

Flexibility and resilience; towards a new platform

You may think you already have a monolithic platform too complex to begin a transition to another type of infrastructure; many have thought the same. However, thanks to the philosophy behind JAMstack, most providers that engage in this type of development are highly flexible.

  • These are polyglot and even CMS-agnostic. In terms of programming languages and connection to various CMS, they are highly compatible, which allows rapid adaptation for development and content management teams, leaving behind the restrictions of conventional development and providing greater freedom during deployment.
  • Thus, by not requiring a bulky backend, platforms are lighter, reducing content loading and delivery times, getting better performance on search engines, and providing a better customer experience, who will browse smoothly even with a considerable increase in traffic. Given the rise in demand, it will be the providers who will automatically increase the capacity of the services, freeing the platform from dealing with this load.
    • In summary, your content and development teams, as well as your customers, will feel relieved and rejuvenated by adopting this development methodology.

      At Reign, we know the differences well, and our developments are based on JAMstack's commandments to achieve results of the highest possible level. We partner with the best microservice providers, who will transform your platform into a fast, secure, and simple experience.
