“…Although they all contribute with valuable insight to the problem domain, none of the proposals have been widespread accepted. The main reason for this might well be that they have been impractical or not been truly transparent from a developer's point of view which is supported by the statement in [17] "Perhaps the most important lesson learned from this effort was that we significantly overestimated the amount of work developers would do in order to gain the benefits offered by an online software upgrading system".…”

Although the Eclipse IDE offers an extremely useful built-in support for developing Eclipse plug-ins, it lacks the ability to perform dynamic updates of plug-ins in a running instance of the application being developed. Because of the nature of the Eclipse architecture and its strict class-loader delegation, plug-ins can only communicate through well-defined APIs. By applying a novel dynamic update approach to the eclipse plug-in development environment that exploits this knowledge, a new API are defined, namely the Dynamic API. This paper discusses some of the ordinary binary compatible changes that lead to erroneous program behaviour if not properly handled. Furthermore, it discusses how applying a dynamic update approach at development time gives developers a unique chance to experiment with dynamic updates without risking a costly shutdown of a real-life application.

“…In addition to DSU systems, we referenced some ideas and categorizations from other surveys in this paper even though some of these surveys have become obsolete protect while others only tangentially relate to dynamic updating without actual focus on this topic . We therefore chose to omit these from our discussion.…”

Application update at run-time remains a challenging issue in software engineering. There are many techniques with different evaluation metrics, resulting in different behaviours in the application being updated. In this paper, we provide an extensive review of research work on dynamic software updating. A framework for the evaluation of dynamic updating features is developed, and the articles are categorized and discussed based on the provided framework. Areas of online software maintenance requiring further research are also identified and highlighted. This information is deemed to not only assist practitioners in selecting appropriate dynamic updating techniques for their systems, but also to facilitate the ongoing and continuous research in the field of dynamic software updating.

“…Current commercial tools that facilitate rolling upgrades provide no way for determining if the interactions between mixed versions are safe and leave these concerns to the application developers [14], [15]. In general, the behavior of a system with mixed versions is not guaranteed to conform to the specification of either version and is hard to test and validate in advance [16]. Moreover, the failures that arise from such component-wise upgrades are not well understood, as prior research on online upgrades focused on evaluating performance and overhead, rather than on the upgrade dependability [10].…”

The fast evolution pace for cloud computing software is on a collision course with our growing reliance on cloud computing. On one hand, cloud software must have the agility to evolve rapidly, in order to remain competitive; on the other hand, more and more critical services become dependent on the cloud and demand high availability through firm Service Level Agreements (SLAs) for cloud infrastructures. This race between the needs to increase both the cloud upgrade frequency and the service availability is unsustainable. In this paper we highlight challenges and opportunities for upgrades in the cloud. We survey the release histories of several cloud applications to analyze their evolution pace, and we discuss the shortcomings with current cloud upgrade mechanisms. We outline several solutions for sustaining this evolution while improving availability, by focusing on the novel characteristics of cloud computing. By discussing several promising directions for realizing this vision, we propose a research agenda for the future of software upgrades in the cloud.
