Scalability

Horizontal and vertical scalability

• Single server design
• • Single server with http server/application/database
• • Drawbacks:
• • • Single point of failure
• • • Does not scale
• • Solution:
• • • Separate the database to different server than http server
• • • little bit of possibility of scale for db and http server separately
• • • Still single point of failure
• Vertical scaling
