Answer: AWS Lambda is a serverless computing service from AWS. It allows you to run code without configuring or managing servers. Using Lambda you can send code functions and have them respond to events.
Lambda automatically evaluates and optimizes your application and allows you to pay for the time your code is used.
Q2: Explain the concept of Amazon S3 (Simple Storage Service) on AWS.
Answer: Amazon S3 is a high-capacity and secure storage service provided by AWS. It is designed to collect and store information from all parts of the web. S3 offers stability, availability and capacity, making it ideal for storing many types of data, including files, photos, videos and backups.
S3 objects are organized into groups, each accessible from a unique URL.
Q3: What is the purpose of Amazon DynamoDB?
Answer: Amazon DynamoDB is a fully managed NoSQL database service from AWS. It offers fast and predictable performance at all scales, making it suitable for applications that require low-latency data access. DynamoDB automatically scales up or down to manage workloads and replicate data across multiple domains for long-term performance.
It provides a flexible data structure and supports data and key points in the warehouse.
Q4: Explain the concept of Amazon VPC (Virtual Private Cloud) on AWS.
Answer: Amazon VPC allows you to set up separate processes on the AWS cloud. It allows you to create AWS resources such as EC2 instances in a virtual network you define. A VPC provides control over the network environment, including IP addresses, subnets, addresses, and gateways.
It allows you to build secure and scalable architectures by connecting public and private subnets and connecting to in-room infrastructure.
Q5: What is AWS CloudFormation?
Answer: AWS CloudFormation is a service that allows you to provision and manage your AWS data using code. It allows you to define your action as code in a template written in JSON or YAML format. CloudFormation templates define resources and their configuration, and CloudFormation is responsible for configuring and managing resources.
This helps create and maintain infrastructure efficiently and automatically.
Q6: Explain the concept of Amazon EC2 (Elastic Compute Cloud) on AWS.
Answer: Amazon EC2 is a web service that provides redundant resources in the cloud. It allows you to place virtual servers called instances and increase or decrease their capacity as you wish. EC2 offers a wide variety of instance types, operating systems, and software configurations.
It gives you full control over your computing resources and is often used for a variety of tasks including web applications, batch processing and big data analytics.
Q7: What is AWS Identity and Access Management (IAM)?
Answer: AWS IAM is a web service that helps you manage access to AWS security resources. It allows you to manage users, groups and permissions in your AWS account. IAM allows you to create and manage multiple user accounts with individual security credentials and tweak permissions for each user or group.
Provides centralized management, security, and monitoring capabilities for your AWS resources.
Q8: What is the purpose of Amazon CloudFront on AWS?
Answer: The purpose of Amazon CloudFront on AWS is to provide a CDN. CloudFront is designed to serve static and static web content such as images, video, HTML files and APIs to end users around the world. Improves performance and reduces latency by caching content in a separate data area at the edge.
By leveraging CloudFront, users can access content from the closest source, reduce load times and improve user experience. It also helps to reduce the load on the central servers by offloading the content sent to the edge site.
CloudFront supports content security through SSL/TLS encryption and integrates with other AWS services, allowing you to easily deliver content from services such as Amazon S3, EC2 or Elastic Load Balancing. It also has features like real-time logging, logging support, and custom caching behavior.
Overall, Amazon CloudFront improves the performance, scalability, and security of web applications by delivering content with low latency and availability to end users around the world.
