Specialized Software Testing for Logistics and Fleet Management


Logistics and transportation companies rely on a sophisticated applications to manage fleet, track shipments, optimize routes, and handle inventory. These applications integrate with various systems, including warehouse management, customer relationship management (CRM), and financial accounting software.

Time and again, logistics companies develop a need to implement major software updates aimed at improving route optimization algorithms and integrating a new customer notification system. However, they face a number of challenges caused by inefficient testing which can lead to the following:

Emergency Rollback: The development team initiates an emergency rollback to the previous stable version of the software. However, due to the lack of a coordinated rollback plan, this process is chaotic and takes longer than anticipated, exacerbating downtime.

Root Cause Analysis: A thorough root cause analysis is conducted to identify all the points of failure in the testing and deployment processes.

Our Solution: Helping Logistics Industry to Launch Optimized Algorithms, Software Updates, and Integrate Flawlessly with Analytics Applications or Data

  • Making configuration changes to ensure flawless API response time for a planned transaction volume of a specified number Order requests per minute.


During the software development lifecycle, the update undergoes extensive testing. However, several issues arise due to inadequate testing procedures:

Inadequate Test Coverage: The testing team focuses primarily on the new features (route optimization and customer notifications) but neglects to comprehensively test the integration points with existing systems.

Insufficient Load Testing: The updated software is not adequately tested for high load scenarios. The logistics application needs to handle peak times with thousands of shipments processed simultaneously, but the load testing is performed with a much smaller data set.

Uncoordinated Deployment: The update is deployed to the live environment without a proper rollback plan or sufficient coordination with other teams responsible for related systems.

Mock Data Discrepancies: During testing, mock data is used instead of real-time data. This leads to discrepancies when the system interacts with real data post-deployment.

The Failure

Once the updated software goes live, the following issues occur:

System Crash During Peak Hours: The application experiences severe performance degradation and eventually crashes during peak operational hours due to unanticipated load. The insufficient load testing fails to reveal this critical issue during the pre-deployment phase.

Route Optimization Malfunction: The new route optimization algorithm contains a bug that wasn’t detected because the testing didn’t cover all edge cases. This results in inefficient routing, causing delays in deliveries and increased fuel costs.

Integration Breakdown: The logistics application fails to communicate properly with the warehouse management system, leading to discrepancies in inventory data. Orders are incorrectly marked as shipped or remain unprocessed, causing chaos in order fulfillment.

Notification System Failures: The new customer notification system sends incorrect or duplicate notifications. Customers receive multiple delivery confirmations and cancellations, leading to confusion and a surge in customer service inquiries.

Financial System Discrepancies: The application generates incorrect billing information, causing issues in financial reconciliation and leading to inaccurate invoices being sent to customers.

Why product engineering teams need DevOps experts who are hands-on with rapid container deployments and orchestration?

The use of containers binds together software development and operational IT skills. It requires the ability to encapsulate code together with libraries and dependencies.  

Some Example Microservices and Dependencies:

  1. Customer Loan Account Management: This microservice handles account creation, modification, credit history mapping, collateral data, etc. It requires knowledge of data querying (e.g., PostgreSQL) to store or retrieve account information.
  2. Collateral Processing Microservice: This microservice manages collateral processing, including credit-check analysis, bill payments, and transaction history retrieval. It may utilize messaging queues (e.g., Apache Kafka) for asynchronous communication.
  3. Authentication Microservice: This microservice handles user authentication and authorization. It may rely on authentication libraries (e.g., OAuth 2.0) for identity management.

Application containerization is effective for recurring background processes involving batch jobs and database jobs. With application containerization, each job can run without interrupting other data-intensive jobs happening simultaneously.

Skills required for containerization?

Along with expertise in handling platforms like Kubernetes for container orchestration, you also need hands-on experience in container distribution management and in enabling hardened API endpoints.

Our ability to spin up new container instances helps run multiple application testing projects in parallel. Our DevOps Engineers are adept at standing-up similar runtime environments – mirroring and production without impacting any other process. Container orchestration is also the key to maintaining uniformity in development, test, and production environments. Our knowledge of code reusability ensures components are used multiple times in many different applications thereby also speeding up developers’ ability to build, test, deploy, and iterate.

The Challenge

Monolithic Architecture

  • The legacy IT system was a rigid monolith running on legacy programming language that did not support new age experiences and struggled to meet compliance
  • The existing monolithic architecture posed challenges in deployment, scalability, and reliability
  • Deploying updates or new features required deploying the entire application, leading to longer release cycles and increased risk of downtime

Limited Scalability

  • Scaling the monolithic application horizontally was difficult, as the entire application had to be replicated to handle increased load.
  • This resulted in inefficiencies and higher infrastructure costs.

Reliability Concerns

  • Monolithic applications are more prone to failures, as a single bug or issue in one part of the application can affect the entire system
  • It can lead to service disruptions and customer dissatisfaction.

Migration planning and high availability

  • Migrating a specific function to an individual microservice requires expert assessment of reusable components, code libraries, and other dependencies that can be clubbed together
  • It is essential to monitor containerized environments to ensure peak performance levels by collecting operational data in the form of logs, metrics, events, and traces


Decomposition of Monolith: Identified and decomposed monolithic components into smaller, loosely coupled microservices based on business capabilities, allowing for independent development, deployment, and scaling.

Containerization of Microservices: Packaged each microservice and its dependencies into separate containers using Docker, ensuring consistency and portability across development, testing, and production environments.

Orchestration with Kubernetes: Deployed microservices on a Kubernetes cluster to automate container orchestration, scaling, and management, enabling seamless deployment and efficient resource utilization.

Service Mesh Implementation: Implemented a service mesh to manage inter-service communication, monitor traffic, enforce security policies, and handle service discovery, improving reliability and fault tolerance.

CI/CD Pipeline Integration: Established CI/CD pipelines to automate the build, test, and deployment processes for microservices, ensuring rapid and reliable software delivery while minimizing manual intervention.


How we Helped

  • Our domain-driven design approach helped define the boundaries of the microservice from a business point of view
  • As each microservice was getting assigned to a different container resulting in a large modular architecture, we structured its management and orchestration
  • Managed Kubernetes enabled optimal pod distribution amongst the nodes
  • Observability generated data to show how much resources would any container optimally need
  • Enabled visualization on the number of clusters, nodes, pods, and other resources for each container
  • Imparted training sessions to learn about containerization tools like Docker and Kubernetes, fostering teamwork across departments
  • The shift to containerization encouraged staff to try new methods, share insights, and continuously learn from each other
  • Regular feedback sessions allowed teams to voice concerns, suggest improvements, and refine containerization strategies over time
  • Milestones in containerization progress leading to new application feature release is speeding modernization initiatives


  • Weeks, not months is the new normal for launching new applications
  • 70% decrease in the time taken for testing and infrastructure provisioning
  • Zero downtime experienced when releasing a new feature in the live environment
  • USD 40,000 saved in operating costs through optimized infrastructure management
  • 45% cost savings in infrastructure and IT operations costs other spent on expensive resources
  • 999% uptime enabled for the applications with use of optimized container orchestration


Simplified Deployment: With microservices, deploying updates became easier. Each service can be updated independently, cutting release times and downtime.

Enhanced Scalability: Microservices allow for flexible scaling of services, reducing costs and optimizing resources as needed. Improved Reliability: By separating services and using a service mesh, the system became more reliable, with fewer disruptions and better user experiences.

Incorrect configuration of Microsoft 365 can lead to non-compliance of HIPAA or Health Insurance Portability and Accountability Act. Ensuring complete adherence to Family Educational Rights and Privacy Act (FERPA) regulations is another important checkbox that a migration plan must cover.

Here are some key steps to ensure HIPAA Compliance with Microsoft 365:

Data Encryption: Encrypt data at rest and in motion on the server

Use a valid SSL certificate: Ensure the Exchange Server has a valid SSL certificate from a trusted authority

Enable Outlook Anywhere: Ensure Outlook Anywhere is enabled and configured properly

Ensure Autodiscover works: Ensure Autodiscover works

Use Microsoft Entra ID: Use Microsoft Entra ID to implement HIPAA safeguards

Check Microsoft 365 subscription: Ensure the Microsoft 365 subscription includes the necessary HIPAA compliance features

Configure security and compliance settings: Configure the necessary security and compliance settings in the Compliance Center

Your migration partner must be mindful of documenting all movement, handling, and alterations made to the data while the migration is underway.

The Challenge

Storage limitations, limited archiving capabilities, and moving over to Microsoft 365 from on premise email exchange are some a key reasons to migrate. End-Of-Life (EOL) and Microsoft Exchange On-premise protocols getting phased are also a big motivation factor.

The constant need to calculate what it costs to support massive volumes of email traffic is influencing migration decision making. But no matter what, the reasons,

Let’s take a look at the other technical challenges often encountered with Office 365 Migration:

  • Many special character from platforms such as Google Workspace are unsupported in Microsoft 365
  • Errors can arise if the folder names and files are unsupported in Microsoft 365
  • Challenges arise when transfer file size packages exceed limits set by Microsoft 365
  • Request limits and API throttling needs to be understood before starting any migration
  • File permission access and user data access requires rigorous permission mapping exercise

Migration Methodology & Approach

Assessment and Planning:

    • Our Migration Specialists will conduct a comprehensive assessment of the existing platform environment, including user accounts, data volume, configurations, and integrations.
    • Develop a detailed migration plan outlining the sequence of tasks, timelines, resource requirements, and potential risks.
    • Coordinate with stakeholders to gather requirements and expectations for the Office 365 environment.

Data Migration:

    • Transfer user emails, calendars, contacts, and other relevant data from platforms like Google Workspace to Office 365 using appropriate migration tools and methods.
    • Migrate shared drives, documents, and collaboration spaces to corresponding Office 365 services (e.g., SharePoint Online, OneDrive for Business, Teams).

Configuration and Customization:

    • Configure Office 365 tenant settings, user accounts, groups, and permissions to mirror the existing Google Workspace setup.
    • Implement custom configurations, policies, and security settings as per client’s requirements.
    • Integrate Office 365 with existing IT infrastructure, applications, and third-party services as necessary.

Integration Challenges Solved: Contract Driven Development and API Specifications to Fulfill Executable Contracts

Case Study

Integration Challenges Solved: Contract Driven Development and API Specifications to Fulfill Executable Contracts


There are several challenges to integration testing that can be solved using Contract-Driven Development and API Testing. Using this methodology, our experts ensure testing of integration points within each application are performed in isolation. We check if all messages sent or received through these integration points are in conformance of the documentation or contract.

A contract is a mutually agreed API specification that brings consumers and providers on the same page. What however makes contract-driven API development complex is the way data is often interpreted by both the provider and consumer.

Let’s consider an example where two microservices, Order Service and Payment Service, need to exchange data about an order. The Order Service provides the order details, including the total amount and customer information, while the Payment Service processes payments.

Typical Scenario: When the Order Service sends the order amount as a floating-point number (e.g., 99.99), but the Payment Service expects the amount as an integer representing cents (e.g., 9999).

Expertise Required:

API Contract: Define the API contract specifying that the order amount is sent as a string representing the amount in cents (e.g., “9999”).

Data Transformation: Implement a data transformation layer that converts the floating-point number to the expected integer format before sending the data to the Payment Service.

Validation: Add validation checks to ensure that the order amount is in the correct format before processing payments.

Our Solution: Enabling API Specifications as Executable Contracts

  • Enabled adherence of API specification as an executable contract
  • Defined API specifications at a component level for consumer and provider applications
  • Deployed API specifications as contract test cases
  • Leveraged Automation Testing Tools to check backward compatibility with existing API Consumers/Clients
  • Automated creation of new connections and test cases on introduction of new environment
  • Built API Specifications that are machine learning parsable codes stored in a central version control system


Semantic Differences:

  • Microservices may have different interpretations of the same data types, leading to semantic mismatches.
  • For example, one service may interpret a “date” as a Unix timestamp, while another may expect a date in a specific format.

Data Serialization:

  • When services communicate over the network, data must be serialized and deserialized.
  • Different serialization frameworks or libraries may handle data types differently, causing mismatches.

Language-Specific Data Types:

  • Microservices may be implemented in different programming languages with their own data type systems.
  • For example, a string in one language may not map directly to the string type in another language.
  • Versioning and Evolution:
  • Changes to data types over time can lead to compatibility issues between different versions of microservices
  • Adding new fields or changing existing data types can break backward compatibility

Null Handling:

  • Null values may be handled differently across services, leading to unexpected behavior
  • Some services may expect null values, while others may not handle them gracefully

How We Helped

API Contract and Documentation:

  • Clearly defined and document API contracts with agreed-upon data types
  • Specify data formats, units, and constraints in API documentation to ensure consistency

Use Standardized Data Formats:

  • Adopt standardized data formats like JSON Schema or OpenAPI to describe API payloads.
  • Standard formats help ensure that all services understand and interpret data consistently.

Data Transformation Layers:

  • Implement data transformation layers or microservices responsible for converting data between different formats
  • Use tools like Apache Avro or Protocol Buffers for efficient data serialization and deserialization

Shared Libraries or SDKs:

  • Develop and share libraries or SDKs across microservices to ensure consistent handling of data types
  • Centralized libraries can provide functions for serialization, validation, and conversion

Schema Registry:

  • Use a schema registry to centrally manage and evolve data schemas
  • Services can fetch the latest schema from the registry, ensuring compatibility and consistency

Schema Evolution Strategies:

  • Implement schema evolution strategies such as backward compatibility
  • When introducing changes, ensure that older versions of services can still understand and process data from newer versions

Validation and Error Handling:

  • Implement robust validation mechanisms to catch data type mismatches early
  • Provide clear error messages and status codes when data types do not match expected formats


  • Conduct thorough testing, including unit tests, integration tests, and contract tests
  • Test scenarios should include data type edge cases to uncover potential mismatches

Versioning and Compatibility:

  • Use versioning strategies such as URL versioning or header versioning to manage changes
  • Maintain backward compatibility when making changes to data types

Code Reviews and Collaboration:

  • Encourage collaboration between teams to review API contracts and data models
  • Conduct regular code reviews to identify and address potential data type mismatches

Runtime Type Checking:

  • Some programming languages offer runtime type checking or reflection mechanisms
  • Use these features to validate data types at runtime, especially when integrating with external services

The Impact

Improved Interoperability: Ensures seamless communication between microservices regardless of the languages or frameworks used.

Reduced Errors: Minimizes the chances of runtime errors and unexpected behavior due to data type inconsistencies.

Faster Integration: Developers spend less time resolving data type issues and can focus on building features.

Easier Maintenance: Centralized data transformation layers and standardized contracts simplify maintenance and updates.

Reimagining Lending Process: Automated Data Streaming Using Kafka and Snowflake

Case Study

Real-Time Data Streaming, Routing, and Processing Using Kafka and Snowflake


A top-tier bank’s legacy messaging infrastructure posed multiple challenges in handling growing data volumes – Transaction Data, Customer Data, New Loan Application Requests, KYC Data, etc. Hence, activating any new digital experience using the existing legacy infrastructure meant enabling high volumes of asynchronous data processing. Traditional messaging middleware like Message Queues (MQs), Enterprise Service Buses (ESBs), and Extract, Transform and Load (ETL) tools were unable to provide the necessary support that modern applications demand.

Modern Applications Require Asynchronous, Heterogeneous Data Processing

What is Asynchronous Data Processing?

Asynchronous processing allows the system to handle multiple loan applications simultaneously without waiting for each application to complete. This means that while one application is being reviewed, others can continue to be processed in parallel.

For example, when a borrower applies for a mortgage loan through an online lending platform, the backend must be capable of collecting required documents and information, such as income statements, tax returns, credit reports, property details, and employment history.

When the borrower submits their application, the system immediately acknowledges receipt and starts the process. Meanwhile, in the background, the system also asynchronously verifies employment history, orders a credit report, and assesses property value.

Why Enable Data Streaming, Routing, and Processing Using APIs?

With the implementation of a Digital API Hub, the Legacy Messaging Middleware gets integrated with modern event streaming automation tools. It can then be taken enterprise-wide to enable new services or functionalities using the existing data.

How are Reusable Microservices Built Using a Modern Messaging layer?

The new messaging layer helps create reusable components from existing topics or data. Hence, launching any new digital service or feature can consume existing topics or data. A topic here implies code that is inside of a Terraform module which can be reused in multiple places throughout an application.

Why Choose Kafka and Snowflake for Real-Time Data Streaming

Snowflake as a data warehousing architecture and Kafka as a platform was chosen to automate different data stream lanes. Our developers were able to used Snowflake to enable event-driven consumption using Snowpipe. By integrating this cloud-based system, we were able to provide easy access to more cloud-based applications for different banking processes and teams.

  • We set up a Java application for data producing teams to scrape an API and integrating it with the data routing platform.
  • Using Kafka as a buffer between data producers and Snowflake allowed for decoupling of ingestion and processing layers, providing flexibility and resilience.
  • Information on different topics is then pushed into further processing for sending our event-driven notifications.
  • We also set up different event-driven data streams that achieves close to real-time fraud detection, transaction monitoring, and risk analysis.

Our Solution: Enabling Modern Experiences Using APIs for Asynchronous Data Processing

At Sun Technologies, we bring you the expertise to integrate event-driven automation that works perfect well with traditional messaging middleware or iPaaS.

Predictive modelling and Data-Driven Demand Planning systems are essential for ‘Empty Container Management’. Global Repositioning Teams use them to reduce logistics costs associated with empty container handling and relocation. However, the ability to predict demand and reposition depends on accuracy and speed of data capture.

What 3PL business therefore need is a solution that can overcome challenges of manual extraction of data from emails, attachments, invoices, shipping labels, delivery notes, CMR Consignment Notes, etc. And while the ever dependable excel spreadsheet is not going anywhere, we can optimize workflows around it.

However, it is largely dependent on the availability of real-time cargo tracking data and how it is used to give the complete picture –

How shipping container dimensions’ data is input into the system

How data is standardized when collaborating with external shipping lines

How data is used to arrive at Projected vs Accrued container storage cost

How data being used to generate a plan for empty load and discharge

What process is followed to create a summary of cargo to be discharged at each port

What process is followed to capture Information location, capacity, and heavy lifts

What type of format you follow for storing data about arrival timestamps

What process is followed to calculate optimal storage figures, and peak periods

Completely manual processes of data extraction, data inputs and maintaining excel-based records pose a big challenge for prediction and visibility. Hence you need system integration that can continuously share the latest data to provide consistency across departments and global divisions.

    • Placing event-based triggers in the Transport Management System (TMS) to raise alerts on future disruptions and plan accordingly
    • Automating data input to show how many last-mile delivery drivers are required at a given time based on shipment status information

How We Can Help: Implement Our Predictive Modelling Accelerators

  1. Auto-populate data: Use of technologies such as OCR creates more robust processes for tracking of inventory levels by scanning barcodes or QR codes on incoming/outgoing shipments, enabling real-time visibility and better inventory control.
  2. Forecast Demand: Once, data related processes are automated, Predictive models can then be used to analyze historical data and other relevant factors to determine the future demand for empty containers. This can help shipping companies and container providers to proactively manage their inventory and ensure optimization of empty containers usage as well as available at the right time.
  3. Optimize Allocation: Our Predictive Modelling acceleration can help in determining the optimal allocation of empty containers to different locations or ports based on predicted demand. This can minimize the need for repositioning containers and reduce costs associated with empty container management.
  4. Optimize Route Planning: Build you customized predictive-modelling-based enterprise application that can analyze historical shipping patterns, trade routes, and other factors to optimize the routing of empty containers. By identifying the most efficient routes for repositioning empty containers, companies can reduce the time and cost required for managing their container inventory.
  5. Plan Maintenance Effectively: Analyze data related to the maintenance history of containers, environmental conditions, and other factors to predict when a container is likely to require maintenance or repairs.
