JAMStack

JAMstack is a web development ecosystem based on client-side Javascript frameworks, reusable APIs and/or micro-services, and prebuilt markup such as static site generators.

With the rise of git-centric workflows, continuous delivery, and the overall popularity of the web - JAMstack architecture provides a modern day approach to building web applications that are scalable, fast and built to maximize a developers' efficiency.

Some Benefits of JAMstack:

Security Static sites have very little vulnerabilities since they have minimal points of entry for attacks. All the dynamic functionality is handled externally with APIs.

Better Performance Monolithic origins that require builds for every visitor can have have poor performance results. Pre-built markup can be served up quickly.

Lower Cost Maintenance costs such as upgrades, backups and general cleanup are all reduced. Hosting flat static files is extremely cost-effective.

Scalability Removes the need for scaled up architecture and is out of the box ready for high traffic.
