Introduction to Cloud Computing - The Need for Cloud Computing

The video tutorial introduces cloud computing, tracing its evolution from early personal computers like the Commodore 64 to client-server architectures. It explains the transition to cloud-based applications, highlighting the benefits of remote storage and third-party management. Key components of cloud applications, such as compute, memory, and storage, are discussed. The tutorial also covers networking basics, including DNS, and addresses challenges like server sprawl, emphasizing the efficiency and cost-effectiveness of cloud solutions.

Why was the client-server architecture developed?

• To reduce the cost of personal computers

• To eliminate the need for personal computers

• To allow personal computers to run faster

• To enable centralized data storage and access

What is a key advantage of cloud computing over traditional client-server architecture?

• It requires more physical space

• Applications are maintained by third parties

• Users have to maintain their own servers

• Applications are stored locally

Which component acts as the 'brain' of an application?

• Database

• Compute (CPU)

• Network

• Storage

What role does RAM play in a computer system?

• It temporarily holds data for quick access

• It processes data

• It stores data permanently

• It connects devices to the internet

What is the function of a DNS server in a network?

• To provide internet connectivity

• To map domain names to IP addresses

• To act as a firewall

• To store data permanently

How do devices in a home network typically connect to the internet?

• Through a switch

• Directly via a modem

• Through a router

• Using a DNS server

What is server sprawl?

• The increase in server efficiency

• The excessive deployment of underutilized servers

• The consolidation of servers

• The reduction of server numbers

What is a major challenge associated with server sprawl?

• Decreased administrative workload

• Increased server efficiency

• Reduced power consumption

• Running out of physical space in data centers

How does cloud computing help address server sprawl?

• By increasing the cost of server maintenance

• By increasing the number of physical servers

• By reducing the need for physical servers

• By complicating the server management process

What is a benefit of cloud computing for a distributed workforce?

• It provides secure and efficient remote access to applications

• It complicates remote access to applications

• It requires employees to work in the office

• It increases the need for physical hardware
