Apa Itu Cloud Computing ( Komputasi Awan ) #technology #science

Summary

This video provides a comprehensive overview of cloud computing, explaining it as an internet-based computing model where IT resources are delivered as a service, allowing users to access applications and data without managing the underlying infrastructure. It traces the history of cloud computing from 1960s mainframes and early remote processing, through the development of private networks and corporate adoption, to modern advancements like Amazon Web Services (AWS) and IBM's Smart Cloud. Key concepts such as SaaS, Web 2.0, and the abstraction of complex infrastructure are highlighted, illustrating how cloud computing has evolved into a foundational technology trend shaping today's digital landscape.

Takeaways

• ☁️ Cloud computing delivers IT services over the internet, allowing users to access software, storage, and processing power without managing underlying infrastructure.
• 💻 It abstracts complex computing systems, presenting them as services accessible through client devices such as desktops, tablets, notebooks, and sensors.
• 📝 According to a 2008 IEI paper, cloud computing stores information permanently on servers and temporarily on client devices.
• 🌐 Key cloud technologies include SaaS, Web 2.0, and other internet-dependent trends.
• 📈 Examples of cloud services include Google Apps for business applications and Apple's iCloud for personal storage and synchronization.
• 🏢 The concept dates back to the 1960s with large-scale mainframe computers accessed via static terminals with no internal processing capability.
• ⚡ In the 1970s, Remote Job Entry (RJE) allowed sharing CPU performance to improve efficiency and return on investment for mainframes.
• 🔮 Visionaries like John McCarthy and Douglas Parkhill compared cloud computing to utilities like electricity, predicting its role as a public computing service.
• ☁️ In the 1990s, companies offered VPNs and private network services, laying groundwork for cloud infrastructure.
• 🚀 Amazon modernized data centers and launched AWS in 2006, becoming a key external cloud service provider.
• 🛠️ Open-source cloud platforms like Eucalyptus and OpenNebula enabled private cloud deployment and international collaboration.
• 💡 IBM’s Smart Cloud framework, announced in 2011, represents a major enterprise adoption of cloud computing within broader initiatives like Smarter Planet.

Q & A

What is the basic definition of cloud computing?

Cloud computing is a method of delivering information technology services over the internet, allowing users to access computing resources without managing the underlying infrastructure.

Why is the term 'cloud' used in cloud computing?

The term 'cloud' is used as a metaphor for the internet, representing an abstraction of complex infrastructure hidden from users.

What are the main types of cloud computing services mentioned in the script?

The script mentions SaaS (Software as a Service) and web-based services, which rely on cloud infrastructure to deliver applications and resources online.

How did cloud computing concepts originate in the 1960s?

In the 1960s, mainframe computers were accessed via static terminals with no internal processing. Sharing CPU performance made mainframe use more efficient, laying the foundation for cloud computing concepts.

Who proposed the idea of computing as a public utility?

John McCarthy proposed that computing could one day be organized as a public utility, similar to electricity.

What role did remote job entry (RJE) systems play in cloud computing history?

RJE systems in the 1970s allowed users to access mainframes remotely, promoting efficient resource utilization and influencing early cloud computing models.

Which companies and organizations contributed to early cloud-related services in the 1990s?

Companies such as GA, Geisco, Time Share, CSS, and telecom providers began offering VPNs and private network services, providing shared computing capabilities.

How did Amazon influence modern cloud computing?

Amazon modernized data centers to improve internal efficiency, then launched Amazon Web Services (AWS) in 2006, offering cloud services to external customers.

What are some examples of open-source cloud platforms mentioned in the script?

Eucalyptus (2008) and OpenNebula were early open-source platforms compatible with AWS APIs, supporting private and European cloud projects.

Why is cloud computing considered an important technology trend today?

Cloud computing provides scalable, internet-dependent IT solutions that improve efficiency, accessibility, and flexibility for businesses and individuals.

How does cloud computing benefit users who are not IT experts?

Cloud computing allows users to access applications and services over the internet without needing technical knowledge or control over the underlying infrastructure.

What analogy did Douglas Parkhill use to explain cloud computing?

Douglas Parkhill compared cloud computing to the electricity industry, showing how computing services could be provided to the public like utilities.
