The Appello Services registry ecosystem is built on a solid foundation of modern Microsoft technologies. The N-tier architected platform leverages a Microsoft SQL back-end database coupled with an ASP.net driven middle-tier used for logic processing, all of which is presented through a web services based front tier. Underneath the application is a multi-site, highly secure layered Firewall configuration and flexible Blade/SAN based infrastructure which complement the N-tier platform. Further efficiency is gained through the use of Windows Server 2008 R2, Microsoft Virtualization and Dynamic Resource Allocation capabilities. Overall this means that Appello Services has highly secure, available and firm technological foundations that can be easily and efficiently scaled to meet the needs of customers now, and in the future.

Appello Services has also partnered with Sublime Group Ltd - Sublime have specialist expertise in the provision of electronic document management and storage services.
