Tearless: Secure Coordination of Rich Internet Application Tiers

Printer-friendly version
January 2016 to December 2019

There is an increasing demand for web-based services that offer collaborative and off-line functionality, and this at unparalleled global scales. Realizing these qualities requires distributing previously centralized application logic and state both vertically and horizontally. Both forms of distribution bring about the essential complexity of maintaining the consistency and safeguarding the security of replicated or shared application assets, along with the accidental complexity of reconciling a myriad of heterogenous tier-specific technology. The Tearless project therefore envisions a future in which multi-tier web applications are developed, tested and maintained as a single artefact that spans all tiers. This tierless programming should relieve developers of distribution, consistency and security concerns. We will not pursue this vision through a new and potentially esoteric programming language. Instead, we will pursue a two-pronged solution of enabling technologies & development tooling. This enables the gradual incorporation of our technology in existing code, and maximizes valorization opportunities for different stakeholders.
