14.What is Amazon Aurora?

Amazon Aurora is a modern relational database service that delivers performance and high availability at scale, fully open-source MySQL-compatible and PostgreSQL-compatible editions, and a range of development tools for building serverless and machine learning (ML)-driven applications.

15.What is Amazon RDS?

Amazon Relational Database Service (Amazon RDS) is a managed service that simplifies setting up, operating, and scaling relational databases in the cloud. It delivers cost-effective, resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.

Amazon RDS gives you access to the familiar functionality of RDS for PostgreSQL, RDS for MySQL, RDS for MariaDB, RDS for SQL Server, RDS for Oracle, or RDS for Db2 databases.

16.What is Amazon Redshift?

For big data analytics, tens of thousands of customers use Amazon Redshift every day to run SQL analytics in the cloud, processing exabytes of data to gain business insights. Whether your growing data is stored in operational data stores, data lakes, streaming data services, or third-party datasets, Amazon Redshift helps you securely access, combine, and share your data with minimal amount of movement or replication. Amazon Redshift is deeply integrated with AWS database, analytics, and machine learning services to use a zero-ETL approach, or give you ready access to data for near real-time analysis, build machine learning models in SQL, and enable Apache Spark analytics with data from Redshift. Amazon Redshift serverless makes it easy for your engineers, developers, data scientists, and analysts to get started and quickly scale analytics in a zero-management environment. With a massively parallel processing (MPP) engine, an architecture that separates compute and storage for efficient scaling, and machine learning-driven performance innovations such as automatic materialized views, Amazon Redshift is built for scale and delivers up to 5x the price/performance of other cloud data warehouses.

17.What is Amazon Virtual Private Cloud?

Amazon VPC allows you to provision a logically isolated section in the Amazon Web Services (AWS) cloud that allows you to launch AWS resources in a virtual network that you define. You have complete control over your virtual network environment, including choosing your own IP address ranges, creating subnets, and configuring routing tables and network gateways. You can also create a hardware virtual private network (VPN) connection between your company’s data center and your VPC to use the AWS Cloud as an extension of your company’s data center.

You can easily customize the network configuration of your Amazon VPC. For example, you can create a public subnet for web servers that have access to the internet, and put back-end systems, such as databases or application servers, in a private subnet that doesn’t have access to the internet. You can leverage multiple layers of security, such as security groups and network access control lists, to help control access to Amazon EC2 instances in individual subnets.

18.What is Amazon Route 53?

Amazon Route 53 provides a highly available and scalable Domain Name System (DNS), domain name registration, and health check web service. Designed to provide developers and businesses with a very reliable and cost-effective way to route end users to Internet applications by translating names, such as example.com, into numeric IP addresses (such as 192.0.2.1) that computers use to connect to each other. You can use DNS in conjunction with the health check service to route traffic to healthy endpoints, or to monitor and/or alert endpoints independently. You can also purchase and manage domain names, such as example.com, and automatically configure DNS settings for your domains. Route 53 efficiently connects user requests to infrastructure running in AWS, such as Amazon EC2 instances, Elastic Load Balancing load balancers, or Amazon S3 buckets, and can also route users to infrastructure outside of AWS.

19.What is Amazon API Gateway?

Amazon API Gateway is a fully managed service that makes it easy for developers to publish, maintain, monitor, and secure APIs at any scale. With just a few clicks in the AWS Management Console, you can create APIs that act as the “front door” to your application to access data, business logic, or functionality from back-end services, including Amazon Elastic Compute Cloud (Amazon EC2), Amazon Elastic Container Service (Amazon ECS), or AWS Elastic Beanstalk and code or arbitrary web applications running on AWS Lambda. Amazon API Gateway manages all the tasks involved accepting and processing thousands of concurrent API calls, including traffic management, authorization and access control, monitoring, and API versioning. Amazon API Gateway has no minimum fees and no startup costs. For HTTP APIs and REST APIs, you only pay for the API calls you receive and the amount of data you send out. For the WebSocket API, you are only charged for the messages you send and receive and the time that the user/device connects to the WebSocket API.

20.What is AWS Direct Connect

AWS Direct Connect is a networking service that provides an alternative to connecting to AWS over the internet. With AWS Direct Connect, data that was previously transferred over the Internet can be transferred over a private network connection between your facility and AWS. In many cases, a private network connection can reduce costs, increase bandwidth, and provide a more consistent network experience than an Internet-based connection。 All AWS services are available in conjunction with AWS Direct Connect, including Amazon Elastic Compute Cloud (EC2), Amazon Virtual Private Cloud (VPC), Amazon Simple Storage Service (S3), and Amazon DynamoDB.

21.Elastic Load Balancing (ELB)

A: Elastic Load Balancing (ELB) supports four types of load balancers

Application Load Balancer (ALB): Load balances HTTP requests
Network Load Balancer (NLB): Network Load Balancer is recommended for load balancing network/transport protocols (Layer 4 – TCP, UDP) as well as extreme performance/low latency applications.
Classic Load Balancer (CLB): Recommended if your application is built in an Amazon Elastic Compute Cloud (Amazon EC2) Classic network.
Gateway Load Balancer: Deploy and run third-party virtual appliances

22.What is Amazon Rekognition?

Amazon Rekognition is a service that makes it easy to add powerful visual analytics to your applications. With Rekognition Image, you can easily build powerful applications to search, verify, and organize millions of images. With Rekognition Video, you can extract motion-based context from stored streaming video or live streaming video and help you analyze it.

Rekognition Image is an image recognition service that can detect objects, scenes, activities, landmarks, faces, dominant colors, and image quality. Rekognition Image can also extract text, identify celebrities, and inappropriate content in images. You can also use the service to search and compare faces.

23.What is Amazon Comprehend?

With Amazon Cognito, you can easily add user registration and authentication capabilities to your mobile and web applications. Amazon Cognito also enables you to authenticate users with an external identity provider and provide temporary security credentials to access your application’s backend resources in AWS or services behind Amazon API Gateway. Amazon Cognito works with external identity providers that support SAML or OpenID Connect and social identity providers such as Facebook, Twitter, Amazon, etc., and you can integrate it with your own identity provider.

30.What is Amazon GuardDuty?

GuardDuty is an intelligent threat detection service that continuously monitors your AWS accounts, Amazon Elastic Compute Cloud (Amazon EC2) instances, AWS Lambda functions, Amazon Elastic Kubernetes Service (Amazon EKS) clusters, Amazon Aurora login activity, and storage in Whether there is malicious activity on the data in Amazon Simple Storage Service (Amazon S3). If potentially malicious activity is detected, such as anomalous behavior, credential compromise, or command-and-control infrastructure (C2) communication, GuardDuty generates detailed security findings that can be used to gain security visibility and assist with remediation. In addition, using Amazon GuardDuty Malware Protection helps detect malicious files on Amazon Elastic Block Store (Amazon EBS) volumes mounted to Amazon EC2 instances and container workloads.
