Rapid Elasticity
On-demand Self-service
Broad Network Access - 15What are the Cloud Service Models?IaaS (Infrastructure as a Service)
Paas (Platform as a Service)
SaaS (Sorftware as a Service) - 16What is IaaS and what can manage the consumer and the provider?IaaS (Infrastructure as a Service) is a cloud service model that provide capability to obtain infrastructure components (servers, storage and network)
Consumer: Apps, data, runtime, middleware and OS
Provider: Virtualization, servers, storage and networking - 17What is PaaS and what can manage the consumer and the provider?Paas (Platform as a Service)
is a cloud service model that provide capability to deploy consumer-created or acquired apps on provider's infrastructure
Consumer: Apps and data
Provider: Runtime, middleware, OS, virtualization, servers, storage and networking - 18What is SaaS and what can manage the consumer and the provider?SaaS (Sorftware as a Service)
is a cloud service model that provide capability to obtain infrastructure components (servers, storage and network)
Consumer: Nothing
Provider: Apps, data, runtime, middleware, OS, virtualization, servers, storage and networking - 19What are the Cloud Computing Deployment Models?Public Cloud, Private Cloud, Hybrid Cloud and Multi Cloud
- 20What is Public Cloud?Is a free, subscription-based or pay-per-use cloud model
Offers a low upfront expenditure on IT resources and enormous scalability - 21What is Private Cloud?A private cloud is a cloud model that offers organizations a greater degree of privacy and control over the cloud infrastructure, applications, and data.
- 22What is the difference between Private Cloud On-premise and Externally hosted?On-premise means that is in the client presmises or in their own Data center.
Externally hosted is when the cloud is located at a third part or provider's premises - 23What is Hybrid Cloud?Is a cloud model composed of two or more distinct cloud infrastructures (private or public)
- 24What is Multi Cloud?Is a cloud model that allows the use of multiple clouds of multiple providers, usually are two or more public clouds that perform different functions
- 25What is Big Data?Information assets whose high volume, high velocity, and high variety require the use of new technical architectures and analytical methods to gain insights and deriving business value
- 26What are the principal aspects of Big Data?
- 27What are the characteristic of Big Data?3 Vs:
1. Volume
2. Velocity
3. Variety - 28Define AI and ML and explain their relation?- AI (Artificial Intelligence)
is an umbrella term that leverages computers and machines to mimic the problem-solving and decision-making capabilities of the human mind
- ML (Machine Learning)
is the process of "training" the machine, feeding large amounts of data into algorithms that give it the ability to learn how to perform the task without being explicitly programmed
ML techniques make AI possible, are two intertwined concepts that help to build human-like ability into systems - 29Explain how work the learning methodsSupervised - Train algorithms given inputs and NOT outputs
Unsupervised - Just provide data and the algorithm sort out the data
Reinforcement - Trial and error method - 30What is IoT?IoT (Internet of Things) is a ecosystem where sensors, devices and equipment are connected to a network and can transmit and receive data
Wearable gadgets
Electronic sensors
Household appliances - 31What are the components of IoT infrastructure?- Smart things: devices that collect, analyze and transmit data
- Gateways: devices that manage data traffic between networks
- Middleware: enables connectivity for huge numbers of diverse Things by providing a connectivity layer for sensors and application layers that provide
- Applications: enable the connection of end users or devices to an IoT device to monitor and control the smart things - 32What is Edge Computing?Edge Computing is an interconnected system of geographically distributed compute and data capabilities working together as a common platform
- 33What is 5G?5G is a fifth-generation mobile
network after 4G networks.
5G is a revolution of mobile technology. Its features and reliability bring tremendous growth in connectivity, mobile traffic capacity, and new capabilities that enhance performance by providing greater throughput, lower latency, ultra-high reliability, higher connectivity density and an expanded range of mobility. - 34What is a Compute System?A compute system is a computing device (combination of hardware, firmware, and system software) that runs business applications.
- 35How is composed the Compute System?- Compute Sistem’s hardware: processor(s), memory, internal storage, and I/O devices.
- Logical components of a compute system: operating system (OS), file system, logical volume manager, and device drivers. - 36What are the types of Compute System?- Tower: is placed within an upright, standalone structure call a "tower”, which looks similar to a desktop cabinet
:( occupy significant floor space and require complex cabling when deployed in a data center.
- Rack-mounted: consist of multiple servers placed into an enclosure called a rack
:) contains multiple servers stacked vertically, thereby simplifying network cabling, consolidating network equipment, and reducing the floor space use.
Blade: consists of several blade servers installed into one or more chassis. Also known as modular servers
:) modular design of the blade servers makes them smaller, which minimizes the floor space requirements, increases the compute system density and scalability, and provides better energy efficiency as compared to the tower and the rack servers.
- 37Explain what is Compute Virtualization and what are the componentsIs a technique of abstracting the physical compute hardware from the operating system and applications enabling multiple operating systems to run concurrently on a single or clustered physical compute system(s).
Components:
- Hypervisor: Specialized OS that allows the virtualization of compute hardware
- Virtual Machine (VM): Software representation of a server - 38What are the types of Hypervisor?* Bare-metal Hypervisor - Tipe 1:
is virtualization software that has been installed directly into the computing hardware.
* Hosted Hypervisor - Tipe 2:
runs inside of an operating system of a physical host machine. - 39What is the difference between Virtual Machines and Containers?*VM: is a logical compute system with virtual hardware on which a supported guest OS and applications run
*Containers: the containerization is an operating system-level virtualization method that simplifies the application deployment
A container require fewer resources that VMs - 40—
