AWS - AWS Services Definitions

GraphQL: Query and manipulation language for APIs

Comprehend: Used for natural language processing, Personal Identifiable Information (PII) detection and redaction, Custom Classification and Entity detection, and topic modeling, enabling a broad range of applications that can analyze raw text, and with some APIs, document formats like PDF and Word.(text analysis)

Lex: Amazon Lex is an AWS service for building conversational interfaces for applications using voice and text. With Amazon Lex, the same conversational engine that powers Amazon Alexa is now available to any developer, enabling you to build sophisticated, natural language chatbots into your new and existing applications.

Polly: Used to convert text to audio

AppSync: An application can fetch required data from multiple sources (like lambda, dynamodb, aurora, http end points or other services) with single network call, Appsync resolver diverts the call to correct data source. 

S3 File Gateway: File gateway using S3. (File Gateway can use S3, FSX, TAP or volume storage to store data) 

Think🤔, How you can store a graph in database? You may think about binary format....answer is here 👇
Neptune: Graph database, store entities with relations

Timestream data

Think🤔, How you can query data from a file which is in S3? .....answer is here 👇
S3 select: Used to query required data from a single object like csv

Think🤔, How you can query data from multiple files which are in S3 like sql database? ....answer is here 👇
Athena: A serverless interactive query service that lets you run full SQL queries directly on data stored in S3.

Redshift Spectrum: Can Query data from Redshift and S3 as well

VPC Endpoint service vs VPC Gateway Endpoint service: Gateway endpoint service is for only S3 and DynamoDB

AWS Trusted Advisor: Provide guidance to provision aws resources following AWS best practices

AWS Personal health dashboard: Provides alerts and guidance for events that might effect your environment. 

AWS Data Pipeline: AWS Data Pipeline is a cloud-based data workflow service that helps you process and move data between different AWS services and on-premise data sources.

Formula to get no. of Ip addresses by mask:

a = 32 - mask

b = 2 pow a

c = b - 5

Ans: c

Ex. Mask is 24 

32-24 = 8

2 pow 8 = 256

256 - 5 = 251

System Manager: A collection of capabilities to help you manage your applications and infrastructure running in the AWS Cloud. A management service that helps you automatically collect software inventory, apply OS patches, create system images, and configure Windows and Linux operating systems. These capabilities help you define and track system configurations, prevent drift, and maintain software compliance of your EC2 and on-premises configurations.

Security Hub: The Security Hub provides a single place in the AWS environment to aggregate, organize, and prioritize security alerts and discoveries from multiple AWS security services. This may be Amazon GuardDuty, Amazon Inspector, Amazon Macie, IAM, Access Analyzer, AWS Firewall Manager. A cloud security posture service that automates security checks and brings security alerts into a central location. 

• Inspector: (For EC2 mostly) An automated vulnerability management service that continually scans AWS workloads for software vulnerabilities and unintended network exposure.
• Macie: (Care your sensitive data) A fully managed data security and data privacy service that uses machine learning and pattern matching to discover and protect your sensitive data in S3.
• Detective: Amazon Detective makes it easy to analyze, investigate, and quickly identify the root cause of security findings or suspicious activities
• Guard Duty: A threat detection service that continuously monitors your AWS accounts and workloads for malicious activity

AWS Keyspace: Service that manages Casendra DB so developer don't have headache to manages hundreds of casandra nodes

Cloud trail Lake: Modernize, fully managed solution for capturing, storing, accessing and analyzing user and API related activities.
It enables you to create a event data store from different resources like events of your applications under aws or on premises. 
Then you can query event data store.

EMR: Big data processing 

AWS Transcribe: Used to convert audio/video to text. Polly does just opposite work.

AWS Translate: Used for text translations to supported languages

AWS Kendra: Used to build search capabilities (like search engine)
