Hardware virtualization instructions enhancing hypervisor efficiency.

The term 'Cloud' originated from its representation in network diagrams describing the Internet in the early 1990s.

Cloud computing operates by using remote servers to store and process data, freeing local devices from heavy workloads.

A virtual machine consists of allocated resources like CPUs and RAM, and data including an operating system and applications.

Cloud computing offers advantages such as reduced local resource usage, scalability, and accessibility from anywhere with an Internet connection.

Businesses and individuals use cloud services for storage, applications, and computing tasks without relying heavily on local hardware.

Cloud computing can be secure, with access controlled through credentials provided by the cloud service provider.

Cloud computing services include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Cloud applications are accessible from any device with the internet.

The cloud offers no size limit for data storage.

More than 50% of workers report working remotely at least half the time.

Sales of desktops decline while laptops, tablets, and smartphones rise.

Cloud security enhances data protection compared to on-premises storage.

Cloud providers monitor access to prevent unauthorized data retrieval.

Providers implement standards for secure data transmission and storage.

Physical security measures control access to cloud service providers’ data centers.

Ensuring the confidentiality, integrity, and availability of customer data is crucial.

Careful monitoring of who can access cloud data protects sensitive information.

Common hypervisors include VirtualBox, VMWare Player, and Parallels Desktop.

A virtualization method where the guest OS is aware it's virtualized and uses a modified kernel.

Hypervisors like XEN, VMWare ESX, and Hyper-V use para-virtualization techniques.

Software that isolates applications, allowing multiple instances to run in execution zones.
