“…The original middleware mainly enables connection and interoperation between networked applications, in order to improve the portability. With the rapid growth of the Internet, the middleware has covered much broader contents and been more widely adopted [11]. First of all, different types of middleware, e.g., database access middleware, remote procedure call middleware, message middleware and distributed computing middleware, become integrated and form a new "synergy middleware".…”

The fast development of the Internet has extended wider space for Information and Communications Technology (ICT), and it has brought a series of challenges for traditional software theories, models, approaches and technologies. This paper looks back some popular Internet-based new computing paradigms and application schemas, discusses the current status and the future trend of software technologies for Internet Computing, including topics of software model, software runtime supporting platform, software development methodologies and software quality measurement and assurance.Internet, software technique, software methodology, Internetware Citation:Mei H, Liu X Z. Software techniques for Internet Computing: Current situation and future trend.The computer software is a set of programs, procedures and documents for specific tasks running on computers. Based on different functions, software can be categorized as application software, system software and supporting software. System software and supporting software are also named as infrastructure software. The ultimate goal of software is to provide better computation services for people. Therefore, satisfying ever-growing application requirements drives the continuous evolution of software techniques. For various application requirements, the research of software technique has developed two parallel approaches. One is software system technology. The core is software nature, characteristics and models, including software basic elements, architecture, interaction protocols, behavior patterns, quality assurance, and so on. Virtualization and system optimization play a significant role in software system technology research. For example, the operating system actually is a virtual machine constructed upon hardware resources; the database systems, the middleware and the application software act likewise in order to provide more *Corresponding author (email: meih@pku.edu.cn) efficient resource management and more natural user interfaces. The other approach is on software development technology, focusing on the software engineering issues, covering the aspects of software development methodologies, engineering principles, supporting tools and environments, etc.Software is essentially a computer program reflecting the real world. It is solidified, elevated and utilized knowledge. Software develops towards more natural models, which are both constructive and evolvable. It always pursues a computing model that is both expressive and natural. A basic software model comprises entity elements and the interactions among them. The model has evolved from the initial machine language instruction with the sequence and jump relationship, to a high-level language statement with the three control structures (sequence, iteration and switch), procedures and the sub-procedures relationship, object orientation with message passing, to the currently popular model of components with connectors. The evolution of computing model greatly facilitates software construction and maintenance. On the o...

“…In order to check if this design evolution can be actually reflected to the running system, we define the following query in WildCAT: V. RELATED WORK As stated in the introduction, our approach is based on models@runtime techniques such as Rainbow [2], ABCTool [3], Plastik [4] which aims at ensuring the synchronization between a running system and its related design models. Rainbow and Plastik focus on the development of SAS by ensuring that selfadaptation does not conflict with static constraints developed at design-time.…”

“…Recent research efforts on Model-Driven Engineering (MDE) such as Rainbow [2], ABCTool [3], Plastik [4] or DiVA [5] tackle the design evolution issue by building a causal connection between abstract design models and the running system. Thus, the designer can refine and update the conceptual models and then automatically synchronize them with the running system, thus preventing developers to write by hand ad-hoc and platformdependent scripts [6].…”

Abstract-The increasing need for continuously available software systems has raised two key-issues: self-adaptation and design evolution. The former one requires software systems to monitor their execution platform and automatically adapt their configuration and/or architecture to adjust their quality of service (optimization, fault-handling). The later one requires new design decisions to be reflected on the fly on the running system to ensure the needed high availability (new requirements, corrective and preventive maintenance). However, design evolution and selfadaptation are not independent and reflecting a design evolution on a running self-adaptative system is not always safe. We propose to unify run-time adaptation and run-time evolution by monitoring both the run-time platform and the design models. Thus, it becomes possible to correlate those heterogeneous events and to use pattern matching on events to elaborate a pertinent decision for run-time adaptation. A flood prediction system deployed along the Ribble river (Yorkshire, England) is used to illustrate how to unify design evolution and run-time adaptation and to safely perform runtime evolution on adaptive systems.

“…Hong Mei et al [2] present a software architecture (SA) centric approach for Internetware's self-adaptation, focusing on the three fundamental issues of self-adaptation including the scope, operability and trustworthiness. Internetware is capable of perceiving the dynamic changes of its environment and adjust itself to meet its functionality, performance, dependability, etc.…”

“…Being one of the basic features of Internetware, self-adaptation means that the software system can monitor its runtime state and behavior and adjust them when necessary according to pre-defined policies [2]. Selfadaptive systems can configure and reconfigure themselves at run time to handle such things as changing user needs, system intrusions or faults, a changing operational environment, and resource variability [3].…”

The increasingly complex environments in which software systems are running today have made runtime software quality unstable and hardly in an optimal state, especially for those systems in open and dynamic environments, e.g. Internetware. In this paper, we explore the effectiveness of software cybernetics and feedback control theory in runtime software quality optimization. We propose a method of runtime quality optimization by using feedback control theory. Specially, we consider the problem of runtime optimization for a specific quality attribute, namely throughput, for Web-based systems. We design a double-layer feedback control model for the problem and implement the runtime optimization control method. In the method, runtime feedbacks are collected and used by the control model to adjust related control parameters. The experimental study has demonstrated the effectiveness of software cybernetics and feedback control theory in runtime quality optimization.
