Use case:
A ride-hailing app uses Load Balancers to handle fluctuating traffic during rush hours.
13. Azure DNS
What it is:
A global DNS hosting service built on Azure’s infrastructure.
Why it matters:
Provides ultra-fast DNS query responses and reliability for web domains.
Use case:
A tech company uses Azure DNS to manage custom domains for its suite of SaaS products.
14. Azure CDN
What it is:
A global content delivery network for caching and distributing web content.
Why it matters:
Reduces latency and accelerates website performance for users worldwide.
Use case:
An online game developer uses Azure CDN to serve downloadable updates and media assets efficiently to players globally.
AI, Analytics & DevOps Tools
15. Azure Machine Learning
What it is:
A cloud platform for training, deploying, and managing machine learning models.
Why it matters:
Streamlines AI development with automated pipelines and compute scaling.
Use case:
A healthcare startup uses Azure ML to train models that detect anomalies in X-ray scans.
16. Azure Synapse Analytics
What it is:
A powerful analytics service combining data warehousing and big data analytics.
Why it matters:
Enables real-time data insights with integration to Power BI and Azure Data Lake.
Use case:
