Summary

TLDRCloud computing evolved from mainframe time-sharing in the 1950s to virtual machines in the 1970s, enabling resource pooling and efficiency. With the rise of the internet, virtualization techniques allowed for cost-effective shared hosting. Hypervisors facilitated multiple virtual systems on one physical node, leading to the pay-as-you-go model. This utility computing approach, allowing scalable resources on-demand, revolutionized computing and paved the way for modern cloud services.

Q & A

  • What was the initial concept of cloud computing?

    -The initial concept of cloud computing dates back to the 1950s with the advent of large-scale mainframes and the practice of time-sharing or resource pooling to efficiently use the computing power of these mainframes.

  • What was the role of dumb terminals in the early days of cloud computing?

    -Dumb terminals facilitated access to mainframes, allowing multiple users to access the same data storage layer and CPU power from any terminal.

  • How did the release of the Virtual Machine (VM) operating system in the 1970s impact cloud computing?

    -The VM operating system allowed for multiple virtual systems or virtual machines on a single physical node, enabling distinct compute environments to exist on the same hardware.

  • What is virtualization and why was it significant for cloud computing?

    -Virtualization is the technology that allows multiple operating systems to run on a single physical server by creating virtual machines, which was a catalyst for the evolution of cloud computing.

  • What was the role of hypervisors in the development of cloud computing?

    -Hypervisors enabled multiple operating systems to run alongside each other on the same physical computing resources, logically separating them and preventing interference.

  • How did the cost of physical hardware influence the shift towards cloud computing?

    -The high cost of physical hardware led to the virtualization of servers into shared hosting environments, which then evolved into cloud computing to make hardware costs more viable.

  • What is the significance of the pay-as-you-go model in cloud computing?

    -The pay-as-you-go model allowed users to pay for computing resources on a per-use basis, which was a key driver behind the adoption of cloud computing.

  • How did the pay-per-use model benefit companies transitioning to cloud computing?

    -The pay-per-use model allowed companies to switch from a capital expenditure (CapEx) model to an operational expenditure (OpEx) model, making it more cash-flow friendly.

  • What is the advantage of cloud computing in terms of scaling workloads?

    -Cloud computing allows companies to scale their workloads during usage peaks and scale down when usage subsides, providing flexibility and cost efficiency.

  • What is the impact of cloud computing on companies with little or no hardware?

    -Cloud computing enables companies with little or no hardware to access computing resources without making large capital investments in physical infrastructure.

  • What are some key considerations for cloud adoption that will be discussed in the next training?

    -The next training will cover key considerations for cloud adoption, which likely include cost analysis, security, compliance, and the selection of appropriate cloud services.
