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.
