How Ksolves Optimize & Modernize Data in Finance Using Apache NiFi?
Our client is a leading diversified financial service provider offering comprehensive services such as wealth management, lending, brokerage, and investment advisory. The organization deals with large volumes of data coming from different sources such as the stock market, customer portfolio, and external vendor systems. Therefore, the organization requires a scalable and efficient data management solution. Our experts implemented Apache NiFi, capable of meeting the demand of real-time trading, decision-making, and regulatory compliance.
The client used SQL Server Integration Services (SSIS) to manage data flows across their infrastructure. However, they faced the following significant challenges:
- Scalability Issues: SSIS pipelines struggled to handle the increasing volume of real-time and batch data.
- Limited Cloud Compatibility: Integrating SSIS with services like Azure Service Bus and Azure Blob Storage required extensive custom scripting and third-party plugins. This increases the complexity of the process and the maintenance overhead.
- Complex API Integrations: Connecting SSIS to external vendor APIs required extensive work because it has limited support for modern protocols like REST and OAuth. This results in additional development efforts for creating and managing custom connectors.
- Operational Inefficiency: The lack of seamless connectivity with external systems led to data processing and synchronization delays. Thereby, impacting the real-time operations and customer experience.
- Inefficient Handling of Large Data Volumes: SSIS needed help to process large datasets efficiently, which led to significant delays in the process. Its parallelism and memory management performance limitations led to prolonged execution times. This is what makes it less suitable for high-volume, real-time, or batch data processing needs.
- Data Latency: Delays in processing real-time data impacted decision-making and customer experience, especially in high-frequency trading and lending scenarios.
- Limited Monitoring Capabilities: SSIS data flows proved challenging due to its lack of intuitive tools for real-time tracking and troubleshooting. Identifying failures or bottlenecks required extensive manual effort, leading to delays in resolving issues and ensuring data reliability.
- Operational Bottlenecks: Managing SSIS across multiple environments required manual intervention, resulting in inefficiencies and inconsistent configurations.
- Inadequate Failure Management and Logging: SSIS needs robust built-in mechanisms for handling data failures and maintaining comprehensive logs. Error tracking often requires custom scripting, making identifying and recovering from failures difficult. This limitation hinders end-to-end data reliability and increases the risk of data loss during processing.
- Limited and Complex Security Features: SSIS has limited built-in security features and relies heavily on the underlying SQL Server for managing access and encryption. Configuring secure connections, protecting sensitive data like passwords, and ensuring compliance with modern security standards (e.g., OAuth, token-based authentication) often require extensive custom implementation. Thereby, increasing the risk of misconfigurations and vulnerabilities.
To address the challenges faced by the client with SQL Server Integration Services (SSIS), we implemented Apache NiFi as a modern, scalable, and efficient data flow management platform. The solution included the following key features:
- High-Availability NiFi Cluster: Deployed a 3-node Apache NiFi cluster to ensure high availability, fault tolerance, and scalability to handle real-time and batch data processing effectively.
- Enhanced Security and Authentication: Implemented OneLogin authentication for secure user access. Configured Role-Based Access Control (RBAC) to ensure granular permissions, providing secure access to flows and system resources. Integrated LDAP with OneLogin, centralizing user management and simplifying authentication processes.
- Real-Time Monitoring and Observability: Integrated Prometheus and Grafana for real-time monitoring of the NiFi infrastructure. This enables detailed insights into data flow performance, system metrics, and cluster health.
- Seamless Integration with Cloud and External Services: Connected Apache NiFi with modern cloud services like Azure Service Bus and Azure Blob Storage. This enables streamlined data ingestion, transformation, and delivery. Integrated with Microsoft SSRS Server for automated report generation. Established connections with external vendor APIs to ensure smooth data exchange using RESTful APIs.
- Flow Management and Version Control: Implemented the NiFi Registry for versioning and storing data flow. This enables seamless deployment across multiple environments and supports CI/CD pipelines.
- Optimized Data Processing: Designed and implemented robust data flows that efficiently process high volumes of real-time and batch data. Ensured data reliability through advanced failure handling, replay capabilities, and comprehensive logging.
- Job Scheduling and Automation: Configured automated job scheduling within NiFi to manage and execute data flows without manual intervention, increasing operational efficiency and reliability.
- Improved Efficiency and Scalability: Replacing SSIS with Apache NiFi significantly enhanced the Client's ability to manage real-time and batch data flows. This ensures seamless scalability and operational efficiency.
- Streamlined Integration: Enabled seamless integration with modern cloud services like Azure Service Bus, Azure Blob Storage, external APIs, and reporting systems. This helped us in addressing previous challenges associated with SSIS.
- Reliable and Continuous Operations: Deployed a high-availability NiFi cluster with robust real-time monitoring using Prometheus and Grafan. For ensuring uninterrupted performance and quick issue resolution.
- Enhanced Security and Access Management: Implementing OneLogin authentication, RBAC, and LDAP integration, safeguards sensitive data. It also simplifies user access management across environments.
- Efficient Flow Management and Deployment: Introduced the NiFi Registry and automated job scheduling, enabling an efficient CI/CD pipeline. It reduces the deployment time and ensures consistent configurations across all environments.
Ksolves data engineers helped the client overcome their data flow management challenges. We worked closely with the client’s team to offer an innovative solution. Our approach involved replacing SSIS with a high-availability NiFi cluster. We integrated Prometheus and Grafana for real-time monitoring. This has helped the organization combine with cloud services and external APIs, providing them with robust real-time tracking and enhancing security.
