Summary of "Qué es la computación o informática en la nube | Conceptos de computación en la nube de AWS"

Summary — main ideas and concepts

Computing (informática): the collection of resources and concepts used to run software — primarily compute (CPUs/GPUs), memory (RAM), networks and storage. Applications that require many CPUs, large RAM, or GPUs are described as computationally intensive.
Cloud computing: on‑demand delivery of IT resources (compute, storage, databases, etc.) over the Internet using a pay‑as‑you‑go model, provided by cloud providers (example: Amazon Web Services).

Cloud computing: on‑demand delivery of IT resources over the Internet using a pay‑as‑you‑go model.

On‑demand provisioning: resources can be activated and deployed in minutes, letting teams move from idea to implementation quickly.
Elasticity and scaling: provision only what you need and scale capacity up or down instantly to match business demand — removes the need to over‑provision for peaks.
Cost model: replaces large fixed costs (data centers, physical servers) with variable costs — pay only for what you use.
Global reach and lower latency: deploy applications in multiple geographic regions in minutes to bring services closer to users and improve performance.
Faster innovation: easy access to a wide range of technologies (IoT, machine learning, analytics, etc.) enables faster experimentation and improved customer experiences.

Core infrastructure: compute, storage, networking, databases.
Managed services: Internet of Things (IoT), machine learning, data lakes, analytics.
Typical use cases: backups, disaster recovery, email, virtual desktops, development & testing, Big Data analytics, customer‑facing web applications.

Provides basic building blocks: virtualized compute, networking, and storage.
Offers the highest level of flexibility and control over IT resources.
Suitable when you need architecture and OS‑level control similar to traditional datacenter resources.

Abstracts and manages the underlying infrastructure (hardware, OS).
Lets developers focus on deploying and managing applications without worrying about provisioning, capacity planning, or patching.
Improves developer efficiency and reduces operational overhead.

Delivers a complete, provider‑managed application (end‑user software such as webmail).
The provider runs and maintains the service and underlying infrastructure; the user consumes the application only.

Free AWS Skill Builder courses are available for further learning (links provided by the speaker).
