AWS IAM

Amazon Web Services (AWS) Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. IAM enables you to create and manage AWS users and groups, and use permissions to allow and deny their access to AWS resources.

Here are some key features of IAM:

  • Centralized control of your AWS account: You can use IAM to manage access to AWS resources for all users within your AWS account, including your own AWS root account.

  • Shared access to your AWS account: You can use IAM to create and manage AWS users and groups, and grant permissions to access AWS resources.

  • Granular permissions: You can use IAM to control access to AWS resources at the individual resource level.

  • Identity federation: You can use IAM to grant access to your AWS resources to users who have been authenticated through an external identity provider, such as Microsoft Active Directory or Facebook.

  • Multi-factor authentication (MFA): You can use IAM to require users to use MFA to access AWS resources, providing an additional layer of security.

  • Identity information management: You can use IAM to manage the identities of your users and the information about those identities, such as name, email address, and phone number.

  • Integration with other AWS services: You can use IAM to control access to other AWS services, such as Amazon EC2 and Amazon S3.


Here is an example of how you can use IAM to control access to an Amazon S3 bucket:

  • Sign in to the AWS Management Console and open the IAM console.
  • In the navigation pane, choose Users and then choose Add user.
  • Enter a user name for the new user and select the check box next to AWS Management Console access.
  • Choose Next: Permissions.
  • On the Set permissions for user page, choose Add user to group.
  • On the Add user to group page, choose Create group.
  • On the Create group page, enter a group name and select the check box next to Amazon S3 Full Access.
  • Choose Create group.
  • On the Add user to group page, select the group you just created and choose Refresh.
  • Choose Next: Review to see the list of permissions that will be granted to the new user.
  • Choose Create user to complete the process.
You can then use the AWS Management Console to sign in as the new user and access the Amazon S3 bucket.

Prompt Engineering Fundamentals

  Introduction Generative AI is a transformative technology capable of producing text, images, audio, and code in response to user prompts. This capability is powered by Large Language Models (LLMs) like OpenAI's GPT series, which are trained to understand and generate natural language. Interacting with these models via prompts allows users to harness their potential without needing technical expertise. This chapter explores the essentials of prompt engineering, a field dedicated to optimizing prompt design for consistent and high-quality responses. Learning Goals By the end of this lesson, you will be able to: Explain what prompt engineering is and why it matters. Describe the components of a prompt and how they are used. Learn best practices and techniques for prompt engineering. Apply learned techniques to real examples using an OpenAI endpoint. Learning Sandbox Prompt engineering is more art than science, requiring practice and iterative refinement. This lesson includes a Jupyt...

AWS Cloud Containers

Amazon Web Services (AWS) offers a variety of services for deploying and managing applications in the cloud. One of these services is called Amazon Elastic Container Service (ECS), which allows you to run and manage Docker containers on AWS. Here is a brief overview of how Amazon ECS works: You package your application into a Docker container image and push it to a registry, such as Amazon Elastic Container Registry (ECR) or Docker Hub. You create an Amazon ECS task definition, which is a blueprint for your containerized application. The task definition specifies things like the Docker image to use, the CPU and memory requirements, and the environment variables to pass to the container. You create an Amazon ECS cluster, which is a group of Amazon EC2 instances that are running the Amazon ECS container agent. The cluster is where your tasks are placed and run. You create an Amazon ECS service, which is a long-running task that is hosted on your cluster. The service ensures that a speci...

Identified COVID-19 in X-ray images with deep learning.

  Project structure :       Our coronavirus (COVID-19) chest X-ray data is in the dataset/ directory where our two classes of data are separated into covid/ and normal/   I have created train_covid19.py file to train the model.   Three command line arguments (parameters) required to run this file :   --dataset: The path to our input dataset of chest X-ray images. --plot: An optional path to an output training history plot. By default the plot is named plot.png unless otherwise specified via the command line. --model: The optional path to our output COVID-19 model; by default it will be named covid19.model.     To load our data, we grab all paths to images in in the --dataset directory. Then, for each imagePath, we:   ·           Extract the class label (either covid or normal) from the path. ·           Load the image, and preprocess it by convertin...
