The RECAP Project: Large Scale Simulation Framework
•
1 j'aime•674 vues
The RECAP project aims to develop an architecture for reliable capacity provisioning and enhanced remediation for distributed cloud/edge/fog applications. The architecture includes a feedback loop consisting of a collector, application modeler, workload modeler, optimizer, and simulator. The collector gathers metrics across the infrastructure. The modelers develop models of application behavior and workloads. The optimizer performs optimization tasks like application placement based on these models. The simulator assists the optimizer by simulating different deployments. The project will apply this architecture to use cases from partners in telecommunications, analytics, IoT, and infrastructure management.

- 2. Agenda • Introduction • The RECAP Vision • Use Cases for RECAP • DCU - Simulation Framework • Intel 2
- 3. What is RECAP? • Reliable Capacity Provisioning and Enhanced Remediation for Distributed Cloud/Edge/Fog Applications • Founded under European Horizon 2020 framework • Jan 2017 – Dec 2019 • Consortium comprises many academic and industrial partners ⁃ 9 partners from 5 countries (Germany, Ireland, Spain, Sweden, UK) • http://recap-project.eu 3
- 5. Project Motivation • Large-scale systems are typically built as distributed systems • Tradeoffs in the placement of application components: ⁃ Data center High latency, high power ⁃ Fog/Edge Low latency, low power • Cloud computing capacity is provisioned using best-effort models and coarsed- grained QoS mechanisms ⁃ Not a sustainable way as the number of connected ”things” increases 5
- 6. Realisation Approach (1/2) • An architecture for cloud-edge computing capacity provisioning and remediation ⁃ Fine-grained and accurate models of application behaviour and deployment ⁃ Model of QoS requirements at application component-level ⁃ Model of workloads • To understand and predict the behaviour of applications (users) • To enhance the proactive remediation of systems 6
- 8. Architecture • Feedback Loop ⁃ Collector ⁃ Application Modeler ⁃ Workload Modeler ⁃ Optimizer ⁃ Simulator 8
- 9. The RECAP Collector • Gathers, synthesizes and analyzes metrics to be monitored across the infrastructure • Acquires, characterizes, and analyzes data ⁃ Workload patterns and their relationship ⁃ Status of the infrastructure ⁃ … • Visualizes, annotates,archives and manages the collected data 9 Knowledge Discovery
- 10. The RECAP Application Modeler • With the knowledge provided by the Collector, the Modeler discovers and defines ⁃ The internal structure of cloud applications ⁃ The QoS requirements for each applications • To support intelligent decision making ⁃ Application/Component placement and autoscaling 10 Application Modeling
- 11. The RECAP Workload Modeler • Decomposes, classifies, and predicts the workloads in the network, and the load propagation in applications ⁃ CPU, memory, network traffic, … • Models the workload distribution and load propagation patterns • To improve planning decision and ensure QoS • To support the construction of an artificial workload generation tool ⁃ Validating and training the learning models 11 Workload Modeling
- 12. The RECAP Optimizer • With the models provided by the Modelers, the Optimizer performs optimization tasks ⁃ Application/Component placement: scaling vs. migration ⁃ Infrastructure management decisions: energy, utilization rate, load balancing • To improve the efficiency in resources utilzation while maintaining QoS 12 Optimization
- 13. The RECAP Simulator • Simulation is needed due to the size and complexity of the intended target systems ⁃ Simulateinteractions of distributed cloud application behaviors ⁃ Emulate data center and network systems • To assist the Optimizer with the evaluation of different deployments of applications and infrastructures • To feed back to the Data Collector with simulation results 13 Testing & Improvement
