A Reference Architecture for Integrated Development And Run-time Environments
Hossein Tajalli and Nenad Medvidovic
Software Development Environments• Augment or automate activities and processes in the software
life-cycle• Spanning requirements elicitation and negotiation• Design• Implementation• Testing and debugging • Deployment • Maintenance• Evolution• Co-ordination of ideas, artifacts, and resources among
involved people
Classification of Tools
Run-time Tools• Classical environments• To support exploratory style of programming• Run-time tools to execute programs and alter running programs• E.g. Interlisp [Tei81], Smalltalk [Gol83], Cedar [Swi85], and The
Rational Environment [Arc86]
• Modern environments• To support self-adaptive software systems • Self-Adaptive Life-cycle Environments (SALEs) • Run-time tools to calculate, validate, and perform run-time
adaptation• E.g. SADE [Don09], PESOI [Tsa06a], PBAAM [Geo04], Rainbow
[Che08], and ArchStudio [Das07]
Existence of run-time tools resulted in the integration of development
and run-time Environments in this systems.
Common Architecture for Self-adaptive Software Systems
Monitors Adapts
Maintains
Advantages of SALEs• Providing artifact updates directly to the adaptation engine• Providing consistent user interfaces to set and control the
behavior of the adaptation engine • Orchestration and integration of the adaptation engine with
other tools to design, generate, validate, and test software adaptation artifacts
• Providing feedback from run-time environment to development environment using adaptation engine
Disadvantages of SALEs• Development and run-time environments have to run
concurrently• Lower availability • Higher resource consumption
iDARE
A reference architecture for integrated Development And Run-time Environments
• Inspired by SALEs• Based on a new perspective:
interaction with the run-time environments• To study and understand development environments• Captures the architecture of disparate development
environments• Improve availability and resource consumption of SALEs

Re-cast Example: PBAAM
The Policy-Based Architectural Adaptation Management (PBAAM) [Geo08] is an automated approach to architectural software adaptation.
Disadvantages of SALEs• Development and run-time environments have to run
concurrently• Lower availability • Higher resource consumption
The detachable tools in iDARE are intended to solve these problems.
PLASMAOur ongoing work on the context of the PLASMA [Taj10] has provided preliminary evidence of iDARE’s utility.
Conclusions• iDARE reference architecture • Study and understand development Environments• New perspective: run-time plug-ins• Improve availability and resource consumption of SALEs• Classifications of development environments
