How to migrate a SQL database to Azure.

1. @RADUVUNVULEA
Azure Tech Series
Database Modernization

2. THE “CLOUD DISILLUSIONMENT”
BLOSSOMS BECAUSE THE METER IS
ALWAYS RUNNING

3. THE BIGGEST ADVANTAGE
PRESENTED BY MODERN CLOUD
TECHNOLOGY IS THE ABILITY FOR
SMALL TO MID-SIZE COMPANIES TO
LEVEL THE PLAYING FIELD

4. BY 2025, 80% OF ENTERPRISES WILL
SHUT DOWN THEIR TRADITIONAL
DATA CENTERS AND SHIFT TO PUBLIC
CLOUD

5. THE HYBRID CLOUD IS THE WEAPON OF
CHOICE FOR 45% OF ENTERPRISES

6. Innovation
