Cloud Basics Flashcards
Pass and thrive
IoE Era
The era of the Internet of Everything (IoE), is characterized by interconnected devices and systems.
Ecosystem Competition
In the IoE era, industries compete for dominance within interconnected ecosystems.
PC Era
Fast changes at the beginning, stable later
- Dominant platforms: Windows OS, Intel chips, x86 architecture
Mobile Era
Fast changes initially, stabilization later
- Dominant platforms: iOS, Android OS
- Architecture: ARM-based systems
The traditional IT architecture consists of
hardware and software, including infrastructure, data centers, servers, network hardware, desktop computers, and enterprise application software solutions.
computer components run on the virtualization environment, not on the physical environment.
With the virtualization technology
With cloud transformation
enterprise data centers are transformed:
from resource silos to resource pooling,
from centralized architecture to distributed architecture,
from dedicated hardware to software-defined storage (SDS) mode,
from manual handling to self-service and automatic service, and
from distributed statistics to unified metering.
Cloud computing adopts a simple distributed parallel programming model called
Map reduce
Is a programming model and task scheduling model. It is mainly used for parallel computing of data sets and scheduling of parallel tasks. In this mode, Users only need to compile Map and Reduce functions to perform parallel computing.
Map-Reduce
Consists of disk files and description files, which are encapsulated in the same folder.
Virtual Machine
Service orientation
Cloud computing is a service model, and the overall design is service-oriented.
Deployment Models for Cloud Computing
Private cloud - the cloud infrastructure is provisioned for the exclusive use of an organization.
Public cloud: the infrastructure is owned and managed by a third-party provider and shared through the internet.
Hybrid cloud: the combination of both mentioned before, viewed as a single cloud externally.
Refers to cloud services provided by third-party providers over the public Internet. Users can enjoy various services, including but not limited to computing, storage, and network services. Public cloud services can be free or pay-per-use.
Public cloud
Abstracts computing, storage, and network resources for users to use and provides corresponding services based on actual application requirements.
The IasS layer.
Provides container services and microservice development services for users based on the IaaS layer. That is, an open platform is provided for users.
The PaaS layer.
Mainly provides scenario-based applications, that is, provides applications as services for users.
SaaS layer.
Public cloud service modes
IaaS, PaaS, SaaS
When users use the cloud, the operating system, database, middleware, and runtime library have been set up.
Compared with IaaS, ______ has low freedom and flexibility and is not suitable for highly professional IT technical professionals.
PaaS is Platform as a Service. A software platform has been built on the cloud, and the customer rents the required software platform.
Users do not need to build data centers. Instead, they rent infrastructure services, including servers, storage devices, and networks.
In terms of usage,_____ is similar to traditional host hosting, but ____ has strong advantages in service flexibility,
scalability, and cost.
Infrastructure as a service
SaaS is based on ______, and PaaS is based on ________.
SaaS is based on PaaS, and PaaS is based on IaaS.
Is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources
Cloud computing
At the ________layer, the public cloud provides user- and platform-oriented______ capabilities. The public cloud provides _______ capabilities for users using cloud services, such as permission control, performance monitoring, status monitoring, and fault alarm reporting.
