Tujuan:
Komputasi awan diwujudkan untuk memberi akses kepada sumber pengkomputeran secara fleksibel dan menjimatkan kos mengikut keperluan tanpa perlu melabur modal awal yang besar bagi infrastruktur fizikal.
Model Cloud:
Cloud Service Model:
- IaaS (Infrastructure-as-a-Service): Menyediakan infrastruktur maya asas seperti VM, storan, dan rangkaian (contoh: AWS EC2, Azure VM).
- PaaS (Platform-as-a-Service): Menyediakan platform lengkap untuk membangunkan serta melancarkan aplikasi tanpa perlu mengurus infrastruktur asas (contoh: Google App Engine, Heroku).
- SaaS (Software-as-a-Service): Aplikasi siap guna yang diakses terus melalui internet tanpa memerlukan pemasangan atau penyelenggaraan oleh pengguna (contoh: Google Workspace, Salesforce).
Cloud Deployment Model:
Merangkumi Public Cloud, Private Cloud, Hybrid Cloud, dan Multi-cloud.
Cloud Architecture
Cloud architecture is a term that’s used to describe the design and organization of a cloud computing system. A cloud computing system typically consists of various components, including computing resources, storage, network infrastructure, security measures, and software applications.
Key Benefit:
- Skalabilitas & Fleksibilitas :
Organizations can easily scale resources up or down to meet fluctuating demand, and users can access systems from anywhere on any device.
- Cost-Efficiency:
Avoids large upfront capital expenses on hardware and uses a pay-as-you-go model.
- Resilience & Disaster Recovery:
Provides built-in redundancy, failover mechanisms, and automated disaster recovery capabilities to ensure high availability and business continuity.
- Advanced Security:
Leverages built-in security features such as encryption, authentication, access control, and web application firewalls (WAFs).
- Enhanced Collaboration:
Supports real-time collaboration with co-authoring, shared storage, version control, and multi-tool integration.
Cloud Component
Cloud computing involves several components, such as VMs, containers, storage, networking, security, databases, and middleware.
