Efficient customization in multi-tenant SaaS

Software as a Service (SaaS) has been increasingly adopted by software vendors as their main software delivery model, as it provides the opportunity to offer their software applications to a larger market and to benefit from the economies of scale. If well-achieved by the SaaS provider, these benefits add value to the offering and reduce the operational costs of hosting and maintaining the SaaS application.

Prosteps goes international with SaaS

The Antwerp software company Prosteps wants to grow internationally via their SaaS-based retail platform, but does not have the necessary know-how in-house. An external advisory board has been set up together with Peter Verhasselt from Sirris that will provide support over the next two years with the international upscaling of their new SaaS product Tilroy. Prosteps specialises in business applications for the retail sector. The company works mainly within the context of ERP solutions for retail chains.

An overview of the OASIS TOSCA standard: Topology and Orchestration Specification for Cloud Applications

Cloud computing has seen an immense rise in recent years, both in new technologies being released as in subsequent use by industry. The use of resources spread across the globe in an on-demand scalable manner, tied to pay-as-you-grow payment schemes, has made the Cloud very attractive. However in part due to this rapid growth, limitations are showing in the majority of Cloud-enabling technologies. More specifically, they lack the capability of providing a standardized view on similar resources served by different providers or through different Cloud middleware solutions. This results in an inability to migrate applications across different platforms without investing high cost and time. This is called the vendor lock-in problem and in order to resolve it, each component of an application, their relationships and management configurations must be encoded in a portable, standardized and a machine readable format.
