1. What is cloud computing?

   Cloud computing adalah model yang menyediakan sumber daya komputasi on-demand—seperti server, penyimpanan, basis data, jaringan, perangkat lunak, analitik, dan kecerdasan—melalui internet, memungkinkan organisasi untuk menskalakan dengan cepat dan membayar hanya untuk yang mereka gunakan.

2. What does the term “cloud” refer to?

   “Cloud” merujuk pada jaringan terdistribusi server dan layanan yang bekerja sama untuk menyediakan sumber daya komputasi on-demand. Biasanya mencakup hardware, perangkat lunak, antarmuka, dan penyimpanan yang bekerja dalam harmoni.

3. What are the core layers of a cloud architecture?

   Dalam stack cloud open-source umum (e.g., OpenStack), layanan inti meliputi:

   • Walrus (object storage)
   • Cloud Controller (CLC) – orchestrates the cloud
   • Node Controller (NC) – manages compute nodes
   • Storage Controller (SC) – handles block storage
   • Cluster Controller – coordinates multi-node operations

4. What are the primary benefits of cloud computing?

   Keuntungan utama meliputi:

   • Scalable and flexible resource allocation
   • Cost-effective pay-as-you-go pricing
   • Robust backup and disaster-recovery options
   • Software as a Service (SaaS) for ready-to-use applications
   • Increased productivity through automation and collaboration tools

5. What types of data are commonly stored in the cloud?

   Beban kerja cloud umum melibatkan:

   • Documents, spreadsheets, and presentations
   • Emails and communication archives
   • Multimedia assets (images, audio, video)
   • Contact lists and CRM data
   • Log files and analytics datasets

6. Which platforms are widely used for large-scale cloud processing?

   Pemrosesan data skala besar biasanya mengandalkan:

   • MapReduce frameworks
   • Apache Hadoop ecosystems

7. What is SaaS?

   Software as a Service (SaaS) delivers fully managed applications over the internet. Users can create, edit, and store documents—like Google Docs—without managing underlying infrastructure.

8. What is on-demand functionality and how does it benefit users?

   On-demand functionality allows users to access virtualized IT resources—applications, servers, storage, and networks—through a shared pool. It provides elasticity, rapid provisioning, and cost efficiency.

9. What is a cloud deployment model, and how many deployment models exist?

   A deployment model defines who owns, manages, and controls the cloud infrastructure. The four main models are:

   • Public Cloud
   • Community Cloud
   • Private Cloud
   • Hybrid Cloud

10. How does mobile computing differ from cloud computing?

    Mobile computing focuses on enabling mobile devices to access services and data remotely, often through the cloud. The cloud acts as the backend that stores and processes data for mobile applications.

11. What are the open-source database platforms used in cloud environments?

    Common open-source databases include:

    • CouchDB
    • MongoDB
    • LucidDB

12. What security benefits does cloud computing offer?

    Cloud providers implement advanced security controls, such as identity and access management, encryption at rest and in transit, and continuous monitoring, which often exceed on-premises capabilities.

13. How do traditional datacenters compare to cloud infrastructure?

    Traditional datacenters typically incur higher upfront capital costs, lower utilization rates, and greater maintenance overhead, whereas cloud infrastructure offers pay-as-you-go pricing, higher scalability, and reduced hardware complexity.

14. How can data be secured during transit in the cloud?

    Data in transit should be encrypted using TLS/SSL protocols, with strong cipher suites and mutual authentication to prevent eavesdropping or tampering.

15. What core resources does the Windows Azure operating system provide?

    Azure offers three primary resource categories:

    • Storage – for persistent data
    • Compute – virtual machines, containers, and functions
    • Administration – management, monitoring, and governance tools
