The Information Explosion is Coming
With the prevalence of the mobile internet and fully connected era, more terminal devices are being use and data is exploding every day.
Challenges Faced by Conventional IT architecture
The internet era has brought a large amount of traffic, users and data to enterprises, but conventional IT architecture cannot meet the requirements for rapid enterprise development
Cloud Computing
Is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g networks, servers, storage, applications and services) that can be rapidly provisioned and release with minimal management effort or service provider interaction.
National Institute of Standards and Technology
Meaning of NIST
Cloud
Is a metaphor for networks and the internet and refers to an abstraction of the internet and the infrastructure that underpins it.
Computing
refers to computing services provided by a powerful computer with a range of functionalities, resources and storage.
Huawei Cloud Meeting
allows interactive video and voice communication between people in two or more locations

The ________ cloud enables access to comprehensive public services through the internet and serves as an extensive service platform with software, application, and information resources provisioned for government bodies.
Public Cloud
Simply put, the ____ enables IT sources to be accessible as electricity and water through the internet
PUBLIC CLOUD/ ENTERPRISE CLOUD
Unified architecture, unfied APIs, Unified Ecosystem
Development Models for cloud computing:
Private Cloud:
The cloud infrastructure is provisioned for exclusive use by a single organization.
Development Models for cloud computing:
Public Cloud
The cloud infrastructure is owned and managed by a third party provider and shared with multiple organization using the public internet.H
Development Models for cloud computing:
Hybrid cloud
This is a combination of public and private clouds, viewed as a single cloud externally.
Eight Common Characteristics of Cloud Computing
Massive Scale, Homogeneity, Virtualization, Resilient Computing, Low Cost Software, Advanced Security Technologies, Geographical Distribution, Service orientation.
Virtualization Technology
refers to the process of creating multiple VMs that share the hardware resources of a physical server.
VM
Consist of dis files and description files, which are encapsulated in the same folder.
Key Concept of virtualization
involves separating software from hardware by converting “physical” devices into “"logical” folders or files.
Virtualization
is the fundamental technology that powers cloud computing. It transform physical hardware into virtual resources, on the other hand, the cloud is an environment that delivers virtualized resources on-demand through the internet.
Main Features of Virtualization
Partitioning
Isolation
Encapsulation
Independence
Important Virtualization Concepts
Physical Server: Application, Host OS (OS running on a physical Machine) , Host Machine
Guest Machine (VM): Applications , Guest OS (Virtual Machine) OS
Hypervisor (virtualization software layer/virtual machine monitor): Host machine (physical machine)
computing
essentially refers to the process of obtaining information. In the ICT industry, several resources are needed to calculate data and obtain information
Huawei Cloud Compute Services:
Elastic Cloud Server (ECS)
VM in Essence
Huawei Cloud Compute Services:
Auto Scaling (AS)

Container
Is a lightweight, portable technology for application packaging. it is a standard unit that packages an application’s code and all its dependencies, enabling the application to run across different computing environments.
Containe Techology Development
Two Challenges in the development of container technology:
Unified playform
Usability
Huawei Cloud Container Services:
Cloud Container Engine (CCE)
A container Instance
Huawei Cloud Container Services:
Cloud Container Instance (CCI)
A container Instance
Huawei Cloud Container Services:
Software Repository for Container (SWR)
Provides images for container instances
What does a router do
Connect your home or office network (LAN) to internet (WAN)
What does a layer 2 switch do?
h connects devices inside the same network and sends data to the correct device using MAC addresses.
Think of it as a smart traffic director inside a local area network (LAN).
What does a layer 3 switch do?
A Layer 3 switch connects different networks and decides where data should go using IP addresses (routing), not just MAC addresses.
Think of it as a Layer 2 switch + router in one device.
NIC Do?
are mainly used to connect different devices. Like a telephone card, they ensure devices can communicate, in addition, NICs can be bound to deliver higher reliability and better network performance.
What does Virtual Switch Do?
Like the bridge and NAT, _________ are used to transmit internal traffic of VMSs to the external network through the network port of the physical server where the VMs Reside.
Common Virtual switches includes?
OVS and EVS
hUAWEI Cloud Network Services
Virtual Private Cloud (VPC)
Isolated, Private virtual networks on Huawei CLoud.
hUAWEI Cloud Network Services
Nat Gateway
Network address translation
hUAWEI Cloud Network Services
Elastic IP (EIP)
Independent public IP resources for ECSs
Mainstream Storage Types:
Block Storage
Maps the entire raw disk space to a server. For Example Five disk in a disk array can be divided into several logical disks, which are then mapped to the server. After partitioning, formatting and mounting on the server, the data is successfully stored.
Mainstream Storage types:
File Storage
Like a shared folder in a file system. users can directly store data on the file storage devices over file system access protocols, such as NFS and CIFS.
Widely used in scenarios such as data back and archive
Mainstream Storage types:
Object Storage
Leverages both block storage and file storage. It offers fast, direct disk access, and distributed file sharing. Generally this outperforms file storage
widely used in data backup and image and video data storage and website hosting
Mainstream Storage types:
Distributed Storage
Virtualize the available storage across all hosts of an enterprise to a virtual storage device, This way, data is stored in different locations on the storage network, improving system reliability, availability and access efficiency.
