GIS has evolved at a rapid pace ever since computers took up to the challenge of providing spatial capabilities. The evolution of GIS from a Map creation platform to a Location Intelligence platform necessitates the need to build systems that are robust, reliable, and elastic as they are utilized to host solutions that your business relies on to be successful. GIS is everywhere running from servers running within traditional data centers, the Cloud, and from mobile and IoT devices. Supporting such a diverse landscape creates unique architectural challenges that require a systematic approach to designing your GIS.
Esri system architecture design is based upon traditional architecture patterns centered around multiple tiers, namely a Client, Presentation, Services, and Data tier. Each tier aligns with Esri products and solution components as depicted by the example logical architecture below. Following a systematic approach, this blog series will explore the various architectural tiers and their related solution components in support of building modern GIS platforms to meet today's business and Location Intelligence needs.
