Cloud Computing Basics

Cloud Computing Basics

What is cloud computing and how has it transformed technology usage?

Cloud computing involves delivering computing services over the internet, reshaping industries by providing scalable, flexible, and cost-effective solutions.

How does cloud computing eliminate the need for local hardware and software resources?

Cloud computing provides access to shared, remotely hosted resources through the internet, reducing the reliance on on-premises hardware and software.

What are the key principles of cloud computing?

The key principles of cloud computing include virtualization, on-demand self-service, and scalability and elasticity.

How does virtualization optimize resource utilization in cloud computing?

Virtualization allows multiple virtual instances to run on a single physical machine, decoupling hardware and software and enabling better scalability and flexibility.

What is on-demand self-service in cloud computing?

On-demand self-service allows users to access computing resources without the need for human intervention from service providers.

What are the cloud computing platforms are populas?

There are four populas cloud computing platform, they are Amazons AWS, Google's GCP, Microsoft's Azure and IBM's IBM Cloud.

How does scalability and elasticity benefit cloud systems?

Cloud systems can dynamically scale resources based on demand, ensuring optimal performance during peak times and cost savings during quieter periods.

What are the three main cloud computing models?

The main cloud computing models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

What is the focus of Infrastructure as a Service (IaaS)?

IaaS provides virtualized computing resources such as virtual machines, storage, and networking, while users have control over operating systems and applications.

How does Platform as a Service (PaaS) benefit developers?

PaaS offers developers a platform to build, deploy, and manage applications without worrying about infrastructure management.

What is the advantage of Software as a Service (SaaS)?

SaaS delivers software applications over the internet, allowing users to access applications from any device with an internet connection without local installations.

What benefits does cloud computing offer in terms of cost efficiency?

Cloud computing eliminates upfront hardware and infrastructure costs, allowing pay-as-you-go models that match expenses with actual usage.

How does cloud computing support scalability and rapid deployment?

Cloud resources can be scaled up or down based on demand, enabling businesses to respond quickly to changing needs without lengthy procurement cycles.

How does cloud computing promote global accessibility and collaboration?

Cloud services are accessible from anywhere with an internet connection, facilitating collaboration across geographical boundaries.

How does cloud computing contribute to resource optimization and green computing?

Cloud providers optimize resource usage, reducing energy consumption and promoting environmentally friendly computing practices.

What are the challenges related to security and privacy in cloud computing?

Storing data offsite raises concerns about data breaches and unauthorized access, necessitating strong encryption and robust security measures.

How does cloud computing address data sovereignty and compliance challenges?

Legal and regulatory requirements conflicting with data storage in different locations pose challenges in data sovereignty and compliance.

What is the concern related to vendor lock-in in cloud computing?

Transitioning from one cloud provider to another can be complex due to proprietary technologies and formats, leading to concerns about vendor lock-in.

How does cloud computing enable business transformation and innovation?

Cloud computing facilitates rapid deployment and testing of new ideas, reducing time-to-market for products and services and promoting innovation.

How does cloud computing empower startups economically?

Cloud services provide startups access to advanced computing resources without high upfront costs, promoting entrepreneurship.

In what ways does cloud computing contribute to education and research advancements?

Cloud computing supports collaborative research by providing computational power for complex simulations and analyses in academic institutions.
