The document discusses the multi-tenancy pattern for cloud deployment. The multi-tenancy pattern describes how a single software application instance can serve multiple tenants by sharing components between tenants. The research enhanced the existing multi-tenancy pattern and applied it successfully to a case study business process management system. Applying the pattern improved the system to meet cloud deployment requirements and allowed components to be shared between tenants for a more efficient cloud architecture.

• Standardized solutions to recurrent
problems
• Reusable solutions to software design
problems
• Represented as templates used in diverse
contexts.
• Single instance of a software application
serving multiple tenants.
• Pattern: describes how application
components that comprises a SaaS
application can be shared between different
tenants.
DESIGN PATTERNS: repeatable solution to
recurring problem in software design
MULTI-TENANCY
• Systematically improved multi-tenancy
pattern and successfully applied to case
study.
• Quality of pattern catalogue is enhanced,
therefore helps developers to make the right
decision on deployment of applications to
the cloud faster.
• The enhanced pattern provides a means for
common language and mechanism for
software engineers undertaking cloud
deployment implementations.

COMPONENT
• Sequential Mixed Method - inductive development of enhanced cloud
deployment patterns and application to case study.
• Explored and compared existing design patterns catalogue with
cloud deployment patterns catalogue available from the literature –
found gaps in the cloud deployment catalogue.
• Filled gaps by creating and applying new template to the patterns.
• Applied our new catalogue template to multi-tenancy patterns.
• Studied an existing business process management software system.
• Redesigned the system to fit cloud requirement.
• Applied multi-tenancy pattern to the software system.
