After achieving his master's degree, Ankit embarked on his professional voyage at Bank of America, starting as an intern. Here, he was part of a team tasked with constructing a new data warehouse using Big Data technologies like Hadoop and Spark. Reflecting on this period, Ankit recalls, "This experience introduced me to the world of Big Data and was pivotal in my career, as our team was at the forefront of integrating Big Data solutions at the bank."

Following his tenure at Bank of America, Ankit transitioned to Microsoft, where his expertise in backend technologies has been leveraged in roles within the Cloud Infrastructure organization and Microsoft Ads. His journey is marked by a blend of academic excellence and practical experience, making him a key figure in the field of backend development.

Solving Complex Business Problems

Service writing and database design are crucial in backend development to ensure seamless data flow and robust performance. Ankit emphasizes, "Efficient services ensure seamless data flow and interaction, while robust database design guarantees data integrity, scalability, and performance." This combination forms the backbone of high-performing applications, enabling advanced data analysis and algorithm implementation.

One notable project at Microsoft involved developing a service to enhance ad quality, making them more informative and engaging, which boosted the click-through rate. The challenge was to display the most relevant data for a given ad based on user searches within a tight timeframe of 2 milliseconds. Ankit designed a service utilizing a highly efficient datastore for quick lookups, allowing the algorithm to determine the best content from multiple candidates swiftly. The result was a significant increase in click-through rates, achieved without noticeable latency, showcasing the power of well-designed data systems in solving complex business problems.

Big Data Technologies and Frameworks

Several technologies and frameworks have proven particularly effective for Ankit in Big Data analysis and data mining. He highlights Apache Hadoop and Apache Spark as foundational tools. "Hadoop's distributed storage and processing capabilities allow us to handle vast amounts of data efficiently," Ankit explains, while Spark's in-memory processing significantly speeds up data tasks, making it ideal for real-time analytics.

For data storage, Ankit relies on Apache HBase and Amazon S3. HBase offers a scalable NoSQL database solution that supports random, real-time read/write access to large datasets. Amazon S3 provides durable and scalable object storage, crucial for storing and retrieving large volumes of unstructured data. In terms of data mining and machine learning, TensorFlow and Scikit-learn are Ankit's go-to frameworks. "TensorFlow's flexibility and scalability make it suitable for deep learning projects," he notes, while Scikit-learn excels at implementing a wide range of machine learning algorithms swiftly and efficiently.

For data visualization and reporting, Ankit turns to Tableau and Power BI, enabling the creation of interactive and insightful visualizations. These tools help stakeholders understand complex data patterns and make informed decisions. One notable project involved developing a predictive system for risk assessment for a financial institution. By leveraging Spark for data processing, TensorFlow for building predictive models, and Tableau for visualization, the team achieved high accuracy in predicting risk assessment. Overall, these technologies and frameworks have empowered Ankit to tackle complex data challenges, derive actionable insights, and drive business value through data-driven decision-making.

Designing Scalable Databases

Designing scalable and efficient databases for large-scale applications like Bing Ads requires a multifaceted approach. Ankit employs several key strategies to meet these demands. One crucial method is data partitioning, where sharding and partitioning distribute data across multiple servers, ensuring load balancing and high availability. Additionally, schema design plays a vital role. Ankit designs flexible and normalized schemas to handle diverse data types and relationships.

Caching mechanisms are also utilized to reduce database load and improve response times, a critical factor in maintaining high performance. Ankit emphasizes "Creating and maintaining efficient indexes to speed up query performance" as a vital strategy. Ensuring data redundancy and regular backups to prevent data loss and enable disaster recovery rounds out these comprehensive strategies. Collectively, these approaches enable the database to handle the high volume and velocity of data typical in ad systems, maintaining both performance and reliability.

Addressing Data Challenges

At Bing Ads, Ankit faced a significant challenge in managing and processing vast amounts of ad data efficiently. The primary issue was ensuring that the system could handle the high volume and velocity of data without compromising performance. To address this, Ankit and his team leveraged other technologies, partitioning the data based on geographic location. "This approach not only improved query performance but also ensured that localized data could be processed closer to its source, reducing latency," Ankit explains.

Advanced indexing strategies were implemented to speed up data retrieval. By creating composite indexes on frequently queried fields, query times were significantly reduced. Caching mechanisms were also employed to store frequently accessed data in memory, further enhancing response times. The system was designed to handle various ad scenarios, such as real-time bidding and personalized ad delivery, without compromising on latency. This involved optimizing data pipelines to process and deliver data in near real-time, ensuring that ads were served promptly and accurately. Utilizing other technologies for orchestrating data workflows, Ankit ensured that the database system was robust, scalable, and capable of meeting the high demands of Bing Ads, maintaining low latency and high performance throughout.

Trends and Advancements in Big Data

In the rapidly evolving field of Big Data, several key trends and advancements are capturing Ankit's excitement. Real-time analytics stands out, with technologies like stream processing and in-memory computing enabling businesses to process and analyze data instantly. "The ability to process and analyze data in real-time is becoming increasingly important," Ankit notes, emphasizing the need for immediate decision-making based on the latest data. Additionally, the integration of AI and machine learning with Big Data is transforming how insights are derived.

Enhanced data governance is another critical trend, addressing growing concerns over data privacy and security. Robust frameworks ensure data is managed responsibly and in compliance with regulations, which is essential as different countries implement their own rules. On-device computing is also gaining traction, with the proliferation of devices and powerful GPUs on laptops allowing data to be processed closer to where it is generated. This approach reduces latency and bandwidth usage, enabling faster decision-making and more efficient data handling.

To stay updated with these developments, Ankit employs a combination of continuous learning, reading, and hands-on practice. He regularly attends industry conferences, webinars, and workshops, subscribing to leading journals, blogs, and newsletters focused on Big Data.
