Study Notes

Traditional IT Architecture

Traditional IT relies heavily on hardware and software, including local data centers, servers, and various enterprise applications.
High energy consumption, physical space requirements, and capital costs characterize traditional setups.
Device performance is limited, leading to low utilization and high overall costs.

Migration to Cloud Architecture

Virtualization allows hardware components to operate independently of physical constraints, enhancing resource utilization and simplifying configurations.
Transition to cloud architecture shifts from siloed resources to pooled resources, implementing distributed systems over dedicated hardware.

Cloud Computing Defined

Cloud computing enables on-demand network access to configurable computing resources, requiring minimal management effort.
It provides an abstraction of the Internet infrastructure and delivers services over the Internet with characteristics like broad access, fast scaling, and resource pooling.

Everyday Cloud Computing Applications

Various applications use cloud computing, including:
- Cloud albums such as iCloud and Baidu Cloud.
- Cloud-based music services like NetEase Music.
- Video services including Baidu Cloud Video and Tencent Cloud Video.
- Document management apps like Youdao Note and Shimo.

Enterprise Cloud Services

HUAWEI CLOUD Meeting: Facilitates interactive communication across remote locations, crucial for industries like healthcare and education, with market growth of over 20% annually.
E-Gov Cloud: Provides governmental bodies with a platform for public services, emphasizing reliability and high availability using existing infrastructural resources.

Containers vs. Virtual Machines (VMs)

Containers virtualize operating systems instead of hardware, allowing more efficient resource usage and better application performance.
Advantages of using containers include:
- Easier and faster application deployment.
- Consistent development across environments.
- Enhanced portability between different cloud and OS platforms.
- Microservices architecture enabling loosely coupled applications.

HUAWEI CLOUD Network Services

Virtual Private Cloud (VPC): Provides users with configurable and isolated virtual networking solutions.
Network Address Translation (NAT) Gateways: Facilitate internet access for cloud servers under different scenarios, enabling public and private networking.

Cloud Storage Mechanisms

Cloud storage enhances data efficiency by decoupling computational power from traditional storage solutions, addressing increased data reliability demands.
Major storage types include:
- Traditional Block Storage: Coupled with local disks; limited capacity and performance.
- File Storage: Hierarchical structure; performance decreases with excess files.
- Object Storage: Flat structure; excels in scale and durability but requires app redevelopment for integration.

Enterprise Storage Options

Direct Attached Storage (DAS): Integrates storage directly with servers via SCSI or FC, lacking separation between data and OS.
Network Attached Storage (NAS): Utilizes network protocols to connect storage devices, allowing data access through private networks.
Storage Area Network (SAN): Interlinks storage arrays and servers across switches, creating dedicated storage networks.
Distributed Storage Systems: Virtualize storage resources across enterprise hosts, improving reliability and efficiency in data access.
