Cloud Computing and Serverless Architecture

Flashcards reviewing vocabulary from lecture on cloud computing and serverless architecture.

Cloud Computing

On-demand computing resources delivered over the internet.

Scalability

Adjust resources dynamically

Cost Efficiency

Pay only for what you use

Flexibility (in Cloud Computing)

Supports diverse workloads

Serverless Architecture

Cloud execution model where providers manage infrastructure, allowing developers to focus exclusively on code.

Function-as-a-Service (FaaS)

Deploy individual functions triggered by events

No Server Management (in Serverless)

Automatic scaling and maintenance; no server management required.

Event-Driven (in Serverless)

Functions execute in response to specific triggers.

Event-Driven Execution

Real-time responses to triggers in serverless architecture.

Infrastructure Abstraction

No server provisioning needed.

Pay-Per-Use Billing

Only charged when functions run.

Auto-Scaling

Handles traffic spikes automatically.

Backend-as-a-Service (BaaS)

Managed backend services.

Cold Start Latency

Initialization delays in serverless functions.

Vendor Lock-In

Migration difficulties due to reliance on a specific provider

State Management (in Serverless)

Complicated workflows when functions need to retain information between invocations

Debugging (in Serverless)

Hard to trace distributed functions in serverless architectures.

AI-Driven Optimization

Auto-tuning functions for performance using AI.

Object-as-a-Service (OaaS)

Simplifies stateful cloud-native apps.

Edge Serverless

Extends FaaS to IoT and edge devices

Hybrid Architectures

Combines serverless with containers/VMs.
