UNIT 3.1 Flashcards
technical and business considerations (10 cards)
What is Cloud Computing?
It is a technology that provides computing services (storage, servers, applications) over the internet instead of using local hardware.
What are key security measures in cloud computing?
Data encryption, IAM (Identity & Access Management), security patching, and compliance with laws like GDPR, HIPAA, and ISO 27001.
How does cloud computing improve scalability?
It allows on-demand resource provisioning, load balancing, and efficient performance monitoring.
What are the three cloud service models?
IaaS (Infrastructure as a Service) – Provides raw computing power (e.g., AWS EC2).
PaaS (Platform as a Service) – Offers a platform for app development (e.g., Google App Engine).
SaaS (Software as a Service) – Delivers ready-to-use software online (e.g., Microsoft 365).
What are the three main cloud migration strategies?
Lift-and-Shift – Moving apps without modification.
Re-architecting – Optimizing apps for cloud-native benefits.
Hybrid Cloud – Using both on-premise and cloud environments.
How does cloud computing help optimize costs?
By shifting IT spending from CAPEX (Capital Expenses) to OPEX (Operational Expenses) and using pay-as-you-go pricing to reduce upfront costs.
How does cloud computing help businesses stay competitive?
A: It enables faster app development, access to AI/Big Data, and remote work capabilities.
Why is legal compliance important in cloud computing?
A: Companies must follow data residency laws and regulatory policies to avoid legal issues.
What should businesses consider when choosing a cloud vendor?
.
A: Factors like uptime guarantees, security policies, support services, and multi-cloud strategies to avoid vendor lock-in
What are the main benefits and challenges of cloud adoption?
Benefits – Scalability, cost savings, flexibility.
Challenges – Security risks, vendor lock-in, compliance issues.
