As websites and web applications get bigger, include more functionality, and become more dynamic, server-based architecture is increasing in complexity. Additionally, security, data and performance requirements lead to further pieces in the architecture puzzle as well as increased maintenance, updating, and upgrading. In today’s tech, features are king, and the time spent working with a complex architecture is time away from features. So what is the problem and what is the solution to combat this growing trend? After all, your company needs to focus on what is important: your business.
In order to keep dynamic web applications secure and performant, server-based architecture has become very complex.
Simple default configurations for databases no longer meet current performance requirements. This requires a lot of action and administration (tuning, redundancies, migration in the CMS, schema adjustment, backups, patches, updates, indexing, etc.).
Without caching, performance is poor. The big challenge is to keep the cache consistent and valid across multiple servers and redundant databases. This required a whole cascade of action (database replication, content consistency, cache invalidation, etc.).
This requires a high degree of administration (back-ups, keeping security plug-ins up-to-date, etc.).
Without Content Delivery Networks (CDN), large videos and images are not readily available. These large files take time to download and the further they are away from the end-user the longer the process takes. Conventional CMSs are not designed for this, which means increased effort (keeping content in sync, versioning, etc.) and poor performance.
The issues of scaling, redundancy for servers and load balancers, development, test and production environments, firewall configuration, patches, updates, etc. are all time-consuming and costly.
The former principle of loading as much of the work as possible onto the webserver is outdated. Today’s user devices have more than enough resources to run web applications. This also includes mobile devices.
Because web functions no longer need to be managed in the server, websites can be designed around microservices. A microservice undertakes a narrowly defined task which is initiated, carried out and terminated independently of other microservices.
The tasks carried out at the backend, such as creating, managing and saving content, are separated from the presentation on a frontend device (so the architecture is headless, or decoupled). Once it has been created, content can be used for any device. The functionality taking place in the frontend and the deployment of individual APIs can now be handled in isolation.
The Jamstack approach has several key advantages over the traditional server infrastructure. It enables higher performance, improves security, lowers costs, scales more easily, and delivers a better user experience.
