Proposed Solution

The proposed solution implements a Cloud Cost Optimization Architecture for a Cloud-Native Batch Processing Application. The application uses Python and Apache Spark for batch processing, while Docker and Kubernetes provide containerized workload deployment and resource management. Prometheus and Grafana continuously monitor compute, memory, storage, and workload utilization. Resource usage is analyzed to identify unnecessary or underutilized resources. Kubernetes scaling and resource limits are adjusted according to workload requirements, while OpenTofu and Ansible automate infrastructure and configuration changes. This approach helps reduce unnecessary cloud resource consumption while maintaining the required batch-processing performance.

Benefits

Reduces unnecessary cloud spending by optimizing compute and storage resource usage.
Improves resource utilization by matching infrastructure capacity with actual batch workloads.
Maintains processing performance by adjusting resources according to workload requirements.
Provides continuous visibility into resource consumption through monitoring and dashboards.
Reduces manual optimization effort through automated scaling and infrastructure management.

Challenges

Finding the right balance between cost reduction and batch processing performance can be challenging.
Workload variations may require frequent resource adjustments and scaling.
Incorrect resource limits can cause processing delays or insufficient application capacity.
Monitoring large numbers of workloads increases infrastructure and operational complexity.
Cost optimization requires continuous analysis because workload and resource requirements can change over time.
