Abstract:
Multi-tenancy is often considered as the key element to economical Software-as-a-Service as it represents an architecture model where one software instance serves a set of multiple clients of different organizations – the so-called tenants. This reduces operational costs due to the decrease of the number of application instances and required resources. Since nearly every multi-tenant system requires a database, this paper focuses on database aspects of multi-tenancy and particularly stresses on cost aspects in public cloud environments. Starting with an investigation of the price schemes of cloud providers, this paper illustrates the broad variety of price factors and schemes. It is discussed in detail why this makes it difficult to set up vendor-independent strategies to achieve cost-efficient multi-tenancy and what challenges arise. Anyway, the paper derives certain, vendor-specific strategies, which require adapting multi-tenant architectures to fit the respective cloud providers’ specifics.
