On-Prem SQL Server vs Azure SQL Database Explained | Azure Data Engineer Mock Interview

Want to crack Azure Data Engineering interviews with confidence? This playlist is your complete roadmap. In this video, I explain a very common interview question: 👉 What is the difference between On-Prem SQL Server and Azure SQL Database? Microsoft SQL Server (On-Premises) is installed and managed on your own servers. We are responsible for hardware, maintenance, backups, patching, and scaling. Whereas Azure SQL Database is a fully managed cloud service provided by Microsoft. It handles infrastructure, backups, patching, and scaling automatically. ✔ On-Prem SQL Server: Full control over infrastructure Manual scaling and maintenance Higher upfront cost (hardware, licenses) ✔ Azure SQL Database: Fully managed (PaaS) Auto scaling and high availability Pay-as-you-go pricing In real-time projects, On-Prem is used when organizations need full control or have compliance requirements, while Azure SQL Database is preferred for scalability, cost optimization, and reduced maintenance. This is not just theory. Every answer is explained the way experienced professionals speak in real interviews. 🔥 What you will learn: Azure Storage Account (Blob vs Data Lake Gen2) Blob Types & Access Tiers (Hot, Cool, Cold, Archive) Azure Data Factory (ADF) real-time pipelines Azure Databricks & PySpark concepts Azure Synapse Analytics (Dedicated & Serverless SQL Pools) Microsoft Fabric (Lakehouse, Warehouse, Pipelines) Medallion Architecture (Bronze, Silver, Gold) Real-time ETL/ELT project design Performance tuning & best practices 🎯 Why this playlist is different: ✔ Real interview questions (not random theory) ✔ Answers explained from 5+ years experience perspective ✔ Project-based explanations ✔ Easy to understand (English + Telugu friendly) ✔ Includes live/mock interview recordings 💡 Perfect for: Azure Data Engineer interview preparation Working professionals with 2–6 years experience Freshers transitioning into Data Engineering Anyone preparing for Microsoft Fabric roles 📌 Pro Tip: Don’t just watch — practice answering in the same format to build confidence. 👉 Subscribe and follow the full playlist to master Azure Data Engineering interviews and land your next job. 📚 FREE LEARNING RESOURCES 👉 Download Our Mobile App: Android: https://play.google.com/store/apps/details?id=co.george.sufkn iOS: https://apps.apple.com/in/app/myinstitute/id1472483563 👉 Login to LMS Portal: https://learn.eclasess.com/courses 🌐 JOIN OUR COMMUNITY 👉 Telegram Channel: https://t.me/eclasess 👉 WhatsApp Channel: https://whatsapp.com/channel/0029VaDTdWa3GJP5EdWohH1x 👉 Job Notifications Group: https://chat.whatsapp.com/Em5dqgBVhzg6dA7aoURw0d 📱 FOLLOW US ON SOCIAL MEDIA 👉 Instagram: https://www.instagram.com/eclasess_edutech 👉 Facebook: https://www.facebook.com/eclasess 👉 LinkedIn: https://www.linkedin.com/in/ram-boyapati-b1758ab9/ 👉 YouTube: https://www.youtube.com/@eclasess 🌍 WEBSITE & SERVICES 👉 Official Website: https://www.eclasess.com 👉 Book 1:1 Session: https://meetpro.club/EclasessRamBoyapati 📞 CONTACT DETAILS 📱 Phone: +91 7989781302 📧 Email: [email protected] 📍 ADDRESS 👉 KPHB, Hyderabad-500072
