Amazon Web Services (AWS) II Introduction to Cloud computing 15 / 42 

AI + Deep/Machine Learning AR & VR / Mixed Reality Blockchain Business Applications Compute Database Data analytics Developer Tools End User Computing Internet of Things Management & Governance / DevOps Networking & Content Delivery Media Services Security, Identity & Compliance Storage Services categories Introduction to Cloud computing 16 / 42 

AI + Deep/Machine Learning Amazon Comprehend (Medical): NLP service to understand text. Useful for extract information from scientific papers. Rekognition + SageMaker: machine learning services. I.e. to de-identify medical images. Introduction to Cloud computing 17 / 42 

AR & VR / Mixed Reality Amazon Sumerian: set of tools to develop AR and VR experiencies, like VR medical simulations. Introduction to Cloud computing 18 / 42 

Business Applications Alexa: voice assistant, like a assistant for emergency communications. Amazon Chime: communications service, for medical remote assistance, i.e. Introduction to Cloud computing 19 / 42 

And the usual stuff Compute: resizable servers, serverless applications, etc. Storage: file and block storage and backup Database: relational databases, key-value storage, etc. Data analytics: Bussiness Intelligence, data mining, etc. Management & Governance / DevOps: monitoring, deployments, automated scaling, etc. Security, Identity & Compliance: cryptographic key management, user access control, etc. Introduction to Cloud computing 20 / 42 

Multi-cloud solutions Use your favourite solutions among different providers. The sky is the limit! Introduction to Cloud computing 21 / 42 

2/3: Beyond the cloud: IoT and Blockchain Introduction to Cloud computing 22 / 42 

Internet of Things Smart objects: connected and autonomous devices Introduction to Cloud computing 23 / 42 

Internet of Medical Things (IoMT) Application of the IoT for medical and health related purposes, data collection and analysis for research, and monitoring Possibilities: Remote health monitoring Emergency notification systems Smart equipment Introduction to Cloud computing 24 / 42 

Blockchain Introduction to Cloud computing 25 / 42 

What is the blockchain? First: (the slowest*) database Second: distributed ledger Third: chain of blocks *: there is a reason for this. Introduction to Cloud computing 26 / 42 

Features (or why is it slow?) We trade off speed for: Decentralization Immutability Trustlessness Introduction to Cloud computing 27 / 42 

How does it work? (Chain of) Blocks: Data: i.e. transactions Hash: Proof of Work (high computational cost) Asymetric key cryptography: identity (encryption and signatures) The result: an emergent consensus Introduction to Cloud computing 28 / 42

Introduction to Cloud computing 30 / 42 

Where is it? Introduction to Cloud computing 31 / 42 

Why use it? Traceable No trusted third parties No central authority Cryptographically secure and immutable Remember: don't store everything in there! Introduction to Cloud computing 32 / 42 

Who is the blockchain? Introduction to Cloud computing 33 / 42 

Introduction to Cloud computing 34 / 42 

How can be used it? Value transfer: Bitcoin Notary and smart contracts Real Estate (and any physicial object): tokenization Distributed computing and storage Digital identity Electronic voting Healthcare - Medical Gambling ... Introduction to Cloud computing 35 / 42 

Medical applications Temperature-Controlled transport monitoring Health records storage and management: Medibloc, Medicalchain & Patientory Mutual Aid Marketplace: MediShares Introduction to Cloud computing 36 / 42 

Wait... Smart contracts? DApps: Distributed apps Stored in the blockchain, so they are: Immutable Distributed Introduction to Cloud computing 37 / 42
