Cloud services are available in a variety of options, tailored to meet customer requirements. The three main cloud computing services defined by the National Institute of Standards and Technology (NIST) in their Special Publication 800-145 are as follows:

Private Clouds

Cloud-based applications and services offered in this cloud are intended for a specific organization or entity, such as the government. A private cloud can be set up using the private network of an organization, though this can be expensive to build and maintain. A private cloud can also be managed by an outside organization with strict access security.

Public Clouds

Cloud-based applications and services offered in this cloud are made available to the general population. Services may be free or are offered on a pay-per-use model, such as paying for online storage. The public cloud uses the internet to provide services.

personal identification number (PIN)

During the pairing process, a _____ may be requested to authenticate the pairing process. The _____ is often a number but can also be a numeric code or passkey. The _____ is stored using pairing services, so it does not have to be entered the next time the device tries to connect. This is convenient when using a headset with a smart phone, because they are paired automatically when the headset is turned on and within range.

Hierarchical

ISPs are critical to communications across the global internet. Each ISP connects to other ISPs to form a network of links that interconnect users all over the world. ISPs are connected in a ____________ manner that ensures that internet traffic generally takes the shortest path from the source to the destination.

Turned off

If your mobile device does not prompt to connect to a Wi-Fi network, the network SSID broadcast may be _______ ____, or the device may not be set to connect automatically. Manually configure the Wi-Fi settings on the mobile device. Remember that SSIDs and passphrases must be typed exactly as entered on the wireless router setup or the device will not connect properly, as shown in the figure.

These are some examples of how devices use Bluetooth:

- Never send login or password information using unencrypted text (plaintext). - Use a VPN connection when possible if you are sending sensitive data. - Enable security on home networks. - Use WPA2 or higher encryption for security.

These precautions should be taken to protect Wi-Fi communications on mobile devices:

The Satellite

This ISP connection option for home users is a good option for homes or offices that do not have access to DSL or cable. This requires a clear line of sight to ____ __________ and so might be difficult in places with overhead obstructions. Speeds will vary depending on the contract, though they are generally good.

Dial-up Telephone

This ISP connection option for home users is an inexpensive option that uses any phone line and a modem. To connect to the ISP, a user calls the ISP access phone number. The low bandwidth provided by this modem connection is usually not sufficient for large data transfer, although it is useful for mobile access while traveling. A modem one of these connections should only be considered when higher speed connection options are not available.

Cellular Internet Access

This ISP connection option for home users uses a cell phone network to connect where so long as you get a signal, you can get access. this benefits people who either have no internet connectivity or people who are always moving.

Community Clouds

This cloud is created for exclusive use by a specific community. The differences between public clouds and these clouds are the functional needs that have been customized for society. For example, healthcare organizations must remain compliant with policies and laws (e.g., HIPAA) that require special authentication and confidentiality.

Hybrid Clouds

This cloud is made up of two or more clouds (example: part private, part public), where each part remains a separate object, but both are connected using a single architecture. Individuals on this cloud would be able to have degrees of access to various services based on user access rights.

Software as a Service (SaaS)

This cloud provider is responsible for access to applications and services, such as email, communication, and Microsoft 365, that are delivered over the internet. The user does not manage any aspect of the cloud services except for limited user-specific application settings. The user only needs to provide data.

Infrastructure as a Service (IaaS)

This cloud provider is responsible for giving IT managers access to the network equipment, virtualized network services, and supporting network infrastructure. Using this cloud service allows IT managers to deploy and run software code, which can include operating systems and applications.

Platform as a Service (PaaS)

This cloud provider is responsible for providing users access to the development tools and services used to deliver the applications. These users are typically programmers and may have control over the configuration settings of the application hosting environment of the cloud provider.

DSL - Digital Subscriber Line

This common connection option for small office and home users provides a high bandwidth, always on, connection to the internet. It requires a special high-speed modem that separates this signal from the telephone signal and provides an Ethernet connection to a host computer or LAN.

Cable

This common connection option for small office and home users typically offered by cable television service providers; the internet data signal is carried on the same coaxial cable that delivers cable television. It provides a high bandwidth, always on, connection to the internet.

Software-Defined Networking (SDN)

This is a network architecture that virtualizes the network, offering a new approach to network administration and management that seeks to simplify and streamline the administration process.

A Hypervisor

This is a program, firmware, or hardware that adds an abstraction layer on top of the physical hardware. The abstraction layer is used to create virtual machines which have access to all the hardware of the physical machine such as CPUs, memory, disk controllers, and NICs. Each of these virtual machines runs a complete and separate operating system.

Internet Backbone

This is like an information superhighway that provides high-speed data links to connect the various service provider networks in major metropolitan areas around the world. The primary medium that connects this is fiber-optic cable. This cable is typically installed underground to connect cities within continents. Fiber-optic cables also run under the sea to connect continents, countries, and cities.

Cloud computing

This is one of the ways that we access and store data. Cloud computing allows us to store personal files, even backup an entire drive on servers over the internet.

Virtualization

This is the foundation of cloud computing. Without it, cloud computing, as it is most-widely implemented, would not be possible.

Control plane

This is typically regarded as the brains of a device. It is used to make forwarding decisions. The control plane contains Layer 2 and Layer 3 route forwarding mechanisms, such as the IPv4 and IPv6 routing tables, and the ARP table. Information sent to the control plane is processed by the CPU.
