Core Cloud Techniques for Scaling
Auto-scaling: Adds servers automatically as load rises and removes them as it falls.
Load balancing: Distributes visitors across servers so none becomes a bottleneck.
Content delivery networks (CDNs): Serve images, scripts, and pages from locations near the customer, which cuts load time.
Caching: Stores frequently requested data, such as product listings, in memory to reduce database strain.
Managed databases with read replicas: Spread read traffic and keep order data safe.
Queues and asynchronous processing: Handle emails, invoices, and inventory updates without slowing checkout.
Monitoring and alerts: Track latency, error rates, and server health in real time.
