To reduce resource over and under-provisioning, software systems can be migrated to IaaS and PaaS-based cloud environments.
However, aligning and optimizing existing software systems for a cloud computing foundation often involves substantial reengineering activities or at least an elaborated configuration during the migration. There exist various challenges that have to be addressed, for example, systematically comparing cloud environment candidates, checking the conformance with particular cloud environments, or simulating monitored workload for envisioned cloud-based target architectures to evaluate future costs.
CloudMIG Xpress addresses those kinds of challenges and provides tool support for the comparison and planning phases to migrate software systems to PaaS or IaaS-based clouds. It originates from an academical prototype and is built to support research in cloud migration.
- Extract code models from Java-based software
- Simulate various cloud deployment options
- Compare the trade-offs that have to be made for different cloud deployment options
- Estimate future costs, response times, and SLA violations
- Model the current system deployment
- Create synthetic workload profiles (e.g., to model usage patterns of existing systems)
- Create workload profiles from real monitoring data
- Model cloud environments with the help of cloud profiles
- Model cloud environment constraints (CECs), e.g., concerning prohibited API calls
- Perform a static analysis to detect CEC violations upon code models
- Compare the suitability of different cloud profiles (e.g., conc. costs and CECs for your software)
- Graph-based visualization of detected CEC violations
