Abstract: Disclosed is a thin film stress control-based coating method for large-area coating. The method uses a two-step coating process in which a first coating layer that is a relatively low-hardness layer is primarily formed on a base member and a second coating layer that is a relatively high-hardness layer is secondarily formed on the first coating layer. The method can form a high-density coating structure that is hardly peeled off over a relatively large area compared to conventional coating methods by suppressing internal stress of the coating layers of the coating structure. Further disclosed is a coating structure manufactured by the same method.

Abstract: Provided are methods and systems for providing users with a tool that can offer recommendations on how to optimize the development and performance of their applications. A diagnosis and optimization method, system, and engine captures various data associated with, for example, building, deploying, releasing, and running a user's application, and utilizes such data to generate recommendations/suggestions as to how the user can best balance high release productivity, ease of management, and cost optimization. The methods and systems utilize the end-to-end story of a user's development process (e.g., from the time the user submits code to when the application is actually up and running) to generate recommendations as to ways that the user can optimize their system including, for example, how the user can layout their application topology differently, reduce latency, increase data locality, or optimize billing costs.
