Emerging large-scale, dynamic and open heterogeneous service computing environments applied to comprehend important services, call for solutions that guarantee high trait and resilience. In practice, the present state of affairs, moreover because the expected evolution of complex service provisioning systems and infrastructures, shows a transparent trend towards dominant characteristics like extreme quality, heterogeneity, mobility, measurability, dynamicity, and a really massive scale of composable parts and services.
To deal with the dynamic nature of large-scale systems and services, moreover like several alternative outstanding practices, like the employment of agile package development methodologies wherever the wants evolve throughout the system lifecycle, new ways and tools area unit required. In observe, we want to research new ways, techniques and tools for improving the resilience and trait of future service package systems.
This paper describes the analysis approach being allotted at the package and Systems Engineering analysis cluster of the Centre for IP and Systems of the University of Coimbra, to address the existing challenges on developing and in operation trustworthy and resilient service package systems.
Development-time and runtime verification & validation
Support traceability to evolving necessities and address successive package releases: Give tools that permit versioning requirements and pursuit evolution. a possible approach is to use multidimensional traceability matrixes that describe the various versions of every demand, permit mapping every version of every requirement with the system design and package code, and allow distinctive interdependencies among existing necessities. The matrix and also the existing data describing the pool of development time V&V checks and results from the previous system versions may be used to determine the checks that require being repeated/updated and people that are still valid.
Support continuous assessment: Observation services and infrastructures are needed for the runtime assessment of the system. This infrastructure which will be custom-made in step with changes should rely on the concept of composing a dynamic network of monitors/checkers deployed at the same time with the creation/evolution of the composite network of services. The monitored info is that the basis for runtime V&V activities throughout dynamic reconfiguration/composition. A key issue is that the V&V techniques which will be applied at runtime may be restricted.
Nowadays, the composition of systems is shifting from development-time to runtime, leading to dynamic service software system systems that evolve when readying so as to adapt to changes in the requirements and infrastructure. This way, we'd like to analysis disruptive techniques and tools for endowing resilience in complicated, high-demand, large-scale, dynamically networked and important service software systems, through a cooperative development, verification & validation, and maintenance, serving as key instrument for guaranteeing their trustiness and gaining confidence in their resilience.
In apply us want methodologies, techniques, and tools that allow:
• Developing, deploying, and in operation resilient service software system systems, considering that they could evolve throughout development-time, and adapt throughout runtime.
• Substantiate and supportive service software system systems at each development-time and runtime, in a very manner that permit evaluating and reassuring their trait and resilience.
• Improving system resilience by activity pro-active maintenance, preventing the incidence of failures.
