AWS for Beginners

Cloud lets you rent other providers' servers instead of managing on-premise hardware, addressing power, connectivity, maintenance, and scalability while you handle access and patch management.

Discover the three leading cloud providers—aws (amazon web services), azure by microsoft, and gcp. Learn why their market leadership and cost considerations drive most organizations to these platforms.

Explore pay-as-you-go cloud billing with no upfront costs or long-term commitments. Compute costs accrue by the hour and storage by the gigabyte, while the provider handles hardware.

Learn to set up AWS billing alerts with CloudWatch, enable billing preferences, configure an SNS email notification, and monitor estimated charges to stay under a daily budget.

Learn how AWS identity and access management (IAM) controls access to AWS services by creating users and granting permissions for resources like EC2 and S3 in your account.

Identity and access management policies define who can access aws and which resources they may access, using users like foobar or Alice as examples and resource restrictions A or B.

Define IAM users as entities holding credentials and attach policies to grant only approved actions, preventing access beyond defined permissions.

Group users into an IAM group to simplify policy management. Attach policies to the group instead of each user, as with a development team of ten.

Understand how IAM roles enable AWS services like EC2 to access resources such as S3, with IAM policies defining allowed actions and noting no additional cost.

Create and attach custom iam policies for s3 access with json and a policy generator, detailing actions, resources, effects, and how users, groups, and roles leverage them with temporary credentials.

Explore AWS S3, the object-based storage for documents, photos, videos, and HTML and CSS content. Learn five GB per object, five TB per bucket, multiple buckets, and hosting a website.

Learn the fundamentals of AWS VPC, the virtual private cloud that creates an isolated network for hosting resources and restricting access.

Explore public and private subnets in a VPC, where public subnets have internet access and private ones do not. Configure route tables and NaCl rules.

Create a VPC named app vpc with 10.0.0.0/24, add a public and a private subnet, attach an internet gateway, and configure a route table for public internet access.

Explore AWS EC2, or Elastic Compute Cloud, a cloud server and virtual machine platform for running apps, with pricing based on hardware usage and server type.

Explore EC2 instance types, from general purpose to compute optimized, memory optimized, and high performance computing, and match CPU, RAM, and GPU needs to big data and machine learning.

Launch an EC2 instance within a VPC public subnet, install Apache, and run it as a web server with a security group enabling HTTP on port 80.
