Development of modern scientific applications makes issues such as composition and integration a significant challenge. Additionally, the Grid technology induces further problems resulting from the distributed, shared, heterogeneous and unreliable nature of resources it offers. For these reasons, programming and running scientific applications on the Grid remains an important and relevant problem. The proposed methodology to address this problem is based on two principles: to follow a component-based programming model and to use a flexible technology for infrastructure virtualization. The author demonstrates how this can be implemented by combining the unique features of the Common Component Architecture (CCA) model together with the H2O resource sharing platform, and how it can be enhanced by a set of methods and tools. The solutions described in this thesis include high-level scripting and descriptor-based approaches, support for multiple programming languages using Babel, interoperability with GCM model, and deployment on existing infrastructures. The MOCCA component framework serves as a basis for those higher-level solutions. Applications and tests included Monte Carlo simulation, domain decomposition of cellular automata, data mining experiments in the ViroLab virtual laboratory, as well as a set of synthetic benchmarks designed to verify the proposed solutions.
