Introduction to Cloud Computing Quiz

Introduction to Cloud Computing

• Cloud computing uses third-party servers to store data.
• It eliminates the need for expensive hardware and database management.

Historical Context

Mainframes and Thin Clients

• Mainframes were large, centralized computers handling all processing tasks.
• Thin clients were simple terminals used to interact with mainframes.

Client-Server Era

• Tasks were shared between individual computers and servers.
• Users could perform basic tasks locally but relied on servers for specific operations, like class registration.

Cloud Computing Advantages

• Data storage and processing are handled externally.
• Enables the Internet of Things (IoT) and smart devices.
• Allows access to data from anywhere with an internet connection.

Key Concepts in Cloud Computing

Definitions

• Cloud Computing: Applications and services running on a distributed network using virtual resources.
• Distributed Network: Multiple users can access and share data.
• Virtualization: Software simulates hardware functions, allowing multiple operating systems on a single machine.

Elastic Leasing

• Elastic: Resources can be dynamically adjusted based on demand to avoid over- or under-provisioning.
• Pooled Resources: Sharing server space reduces costs through economies of scale.

Security in Cloud Computing

• Encryption: Protects communication by encoding messages for authorized users only.
• Firewalls: Limit network access, acting as barriers to unauthorized users.
• Virtual Private Networks (VPNs): Create secure, private connections over public networks, often used for accessing sensitive data remotely.

Types of Cloud Services

Infrastructure as a Service (IaaS)

• Provides basic storage and computational resources with minimal additional features.

Platform as a Service (PaaS)

• Offers a platform for developing, running, and managing applications without infrastructure management.

Software as a Service (SaaS)

• Delivers software applications over the internet, eliminating local installation requirements.

Considerations for Cloud Usage

• Security Concerns: Some industries require in-house data management for security compliance.
• Cost and Scalability: Cloud services offer cost-effective and scalable solutions for businesses.
