Why You Need DevOps Engineers and Cloud Architects to Configure Automated Streaming Workflows in a Multi-Cloud Environment?



DevOps Engineers and Cloud Architects play an active role in planning and managing coding tasks. This ensures the developed code aligns with deployment requirements and business objectives. To do so, a skilled DevOps Cloud Architect and Data Engineer must have expertise in configuring streaming workflows from a hybrid cloud environment, where data is both on-premises and in the cloud.

When deploying applications, the team would need to be adept at using tools like Terraform and Ansible to define and manage infrastructure for any new release or for duplicating IT infrastructure at different branch locations. Prior to any software or new feature release, their expertise in using tools like Jenkins and GitLab CI will help the DevOps team to automate testing of code changes and catch issues early. This also requires hands-on experience in coding for performing conversions or refactoring when re-platforming codes from legacy systems like COBOL to Java & Angular.

Discover how No-Code API integrations are modernizing Legacy Messaging Infrastructure by integrating it with decoupled Automated Data Streams.

For example, for one of our banking clients, we enabled event driven data streaming for processes involving each of the following: Treasury Management, Lending & Underwriting, Guarantee Management, Information Security, and/or Regulatory Compliance.

Our Legacy Integration specialists are not only helping the bank identify the right data pipelines, but also launching new functionalities using No-Code API plugins.


Below, we have listed some critical tasks that DevOps teams need to fulfil using specialized Data Engineering skills:

  1. Integration of On-Premises and Cloud Systems:
  • Connectivity: Data engineers establish secure and reliable connections between on-premises data sources (databases, applications, IoT devices) and cloud platforms (like AWS, Azure, Google Cloud)
  • APIs and Middleware: Utilize APIs and middleware tools to facilitate data transfer and integration between different environments
  • Data Gateways: Set up data gateways to securely transfer data from on-premises systems to the cloud
  1. Streaming Data Ingestion:
  • Choose Streaming Platforms: Select appropriate streaming platforms such as Apache Kafka, AWS Kinesis, or Azure Stream Analytics for collecting real-time data
  • Setup Connectors: Implement connectors or adaptors to bridge on-premises data sources with cloud-based streaming platforms
  • Schema Management: Ensure consistent schema management across on-premises and cloud systems to avoid compatibility issues
  1. Data Transformation and Enrichment:
  • ETL Processes: Create Extract, Transform, Load (ETL) processes to transform raw data into a usable format for analytics
  • Enrichment: Add additional context or metadata to the streaming data for better insights
  • Streaming SQL: Use streaming SQL languages (like KSQL, Spark SQL) for real-time transformations
  1. Monitoring and Management:
  • Performance Monitoring: Set up monitoring tools to track the performance of streaming workflows, both on-premises and in the cloud
  • Alerting: Configure alerts for anomalies or issues in the data flow
  • Resource Management: Optimize resource allocation and utilization for cost efficiency
  1. Data Quality and Governance:
  • Data Quality Checks: Implement checks to ensure data quality during ingestion and processing
  • Metadata Management: Establish metadata catalogs to track data lineage, schemas, and usage
  • Compliance: Ensure compliance with data governance policies and regulations across hybrid environments
  1. Scalability and Fault Tolerance:
  • Auto-Scaling: Configure auto-scaling mechanisms for streaming platforms to handle varying workloads
  • High Availability: Design workflows with redundancy and failover mechanisms to ensure continuous operation
  1. Data Security:
  • Encryption: Implement end-to-end encryption for data in transit and at rest
  • Access Control: Configure role-based access controls (RBAC) to restrict access to sensitive data
  • Data Masking: Mask or anonymize sensitive data to protect privacy
  1. Testing and Validation:
  • Unit Testing: Develop and execute unit tests for individual components of the streaming workflow
  • Integration Testing: Test the entire workflow end-to-end to ensure seamless data flow
  • Data Lineage Testing: Verify data lineage to ensure data integrity and accuracy
  1. Documentation and Knowledge Sharing:
  • Workflow Documentation: Document the configuration, architecture, and processes for the streaming workflows
  • Training: Conduct training sessions for other team members on how to manage and troubleshoot the hybrid cloud streaming environment

Real-world example of the technologies and tools used by Data Engineers to configure hybrid cloud streaming workflows:

Data Ingestion:

  • Use Apache Kafka as a streaming platform
  • Set up Kafka Connect to pull data from on-premises databases
  • Implement a secure data gateway for transferring on-premises data to the cloud

Data Transformation:

  • Use Kafka Streams for real-time data processing
  • Transform raw data formats from on-premises systems into a unified schema
  • Enrich streaming data with additional context using Kafka Streams APIs

Data Storage:

  • Store processed data in Amazon S3 buckets in the cloud
  • Use partitioning and bucketing strategies for efficient data storage and retrieval

Analytics and Visualization:

  • Configure Apache Spark for batch analytics on the cloud
  • Use Amazon Redshift for data warehousing and ad-hoc querying
  • Connect Tableau or Power BI for real-time dashboards and visualization

Monitoring and Management:

  • Set up Amazon CloudWatch for monitoring Kafka and Spark clusters
  • Configure alerts for data processing delays or errors
  • Use AWS Auto Scaling to scale resources based on workload demands

Security and Compliance:

  • Enable SSL encryption for data in transit between on-premises and cloud environments
  • Implement IAM roles and policies for access control to cloud resources
  • Mask sensitive data fields in streaming pipelines to comply with data privacy regulations

Testing and Validation:

  • Develop unit tests for Kafka Streams applications and Spark jobs
  • Perform end-to-end integration testing of the entire streaming workflow
  • Validate data lineage and ensure data quality at each stage of the process

Documentation and Knowledge Sharing:

  • Create detailed documentation on the streaming architecture, including diagrams and configurations
  • Conduct training sessions for data engineers and analysts on managing and troubleshooting the hybrid cloud streaming environment

The Impact of DevOps and Data Engineering Skills:

Real-Time Insights: Enables real-time data processing and analytics for timely decision-making.

Scalability: Scales to handle large volumes of data from diverse sources.

Cost Efficiency: Optimizes resource usage and minimizes operational costs.

Flexibility: Allows for seamless integration and data flow between on-premises and cloud environments.

Reliability: Ensures fault tolerance and high availability of streaming workflows.

By leveraging the expertise of data engineers, organizations can successfully configure and manage complex streaming workflows in a hybrid cloud environment. This enables them to harness the power of real-time data for actionable insights, improved operations, and better business outcomes.
