AWS For Absolute Beginners: Learn AWS From Ground Up

Explore core AWS services from EC2 instances to S3 storage, IAM access control, Route 53 DNS, security groups, AMIs, auto scaling, and relational versus non-relational databases.

Install and set up essential tools like PuTTY and PuTTYgen for Windows, SSH access to EC2 instances, and obtain a domain name to begin your AWS journey.

Create your Amazon Web Services account, attach a credit card, and enroll in the free tier for 12 months to launch your first EC2 instance.

Log into the AWS management console and explore the interface, including services, my account, billing and cost management, and security credentials. Review payment methods and access the support center.

Launch your first EC2 instance from the AWS console by selecting a free-tier Ubuntu Server AMI and a T-2 micro, with SSH on port 22 and a key pair.

Learn to log in to an EC2 instance using Putty with SSH by converting PEM to PPK, saving the private key, and using public DNS with the correct username.

Discover how Amazon Route 53 provides a scalable DNS service with health checks, traffic flow routing, and domain registration, plus detailed pricing for hosted zones, policy records, and queries.

Learn how to host a domain on an EC2 instance using Route 53, including creating a hosted zone, configuring NS and SOA records, and updating name servers at your registrar.

Learn how to host a domain on an S3 bucket using Route 53 by creating two S3 buckets, enabling web hosting, and configuring alias records and name servers.

Create a wildcard dns record in Route 53 by adding a star in the name within a hosted zone, using alias for S3 or an IP for EC2.

Learn AWS IAM features to securely manage access with granular permissions, shared access, and federation, while using roles for apps and relying on a free, highly available service.

Navigate to the security and identity section to create a root account, add a new user, download credentials, and attach the administrator access policy for IAM access.

Learn to set up and connect a Microsoft Active Directory in the AWOS cloud with the AWS directory service, including simple AD and AD connector options, and enable single sign-on.

Understand how identity and access management uses permissions to control who can access AWS resources, what actions they can perform, and how identity-based and resource-based permissions differ.

Create an S3 bucket in the AWS console by navigating to storage and content delivery, naming the bucket, and selecting a region, then review its properties for future configuration.

Upload files to a newly created S-3 bucket and make them public. Enable static website hosting and access the content via an Amazon endpoint.

Discover how to configure an AWS S3 bucket, including permissions and access policies, static website hosting, logging, versioning, lifecycle rules, cross-region replication, tags, requester pays, and transfer acceleration.

Create an Amazon Machine Image (AMI) from an existing EC2 instance to produce a complete duplicate, explore no reboot options, and launch a new instance from the AMI.

Launch an EC2 instance from a previously created AMI by selecting the image, choosing a t2.micro, and pairing an existing key, then review and launch.

Create an auto scaling group from a custom AMI by building a launch configuration, selecting instance type, and configuring scaling policies with CloudWatch alarms and SNS notifications.

Auto scaling groups automatically adjust EC2 instances to match traffic, with configurable minimum, maximum, and desired capacity, and scaling policies for cost management, fault tolerance, and availability.

Identify security groups as virtual firewalls that control traffic to EC2 instances. Use inbound rules to allow web traffic on port 80 from the internet and outbound rules to permit responses, or restrict sources to specific IPs for private testing.

Learn to use security groups to forward ports on an EC2 instance. Configure inbound and outbound rules for http 80, https 443, and ssh or ftp access.

Explore AWS database options from managed relational databases to NoSQL, including RDS, DynamoDB, ElastiCache, and Redshift. Learn how the managed database migration service minimizes downtime during migrations.

Launch your first RDS instance by selecting an engine, sizing the DB instance, and configuring network, security, and backups. Review the cluster endpoint and port when ready.

launch a single-node Amazon Redshift data warehousing cluster, configure networking and security groups, choose encryption options, and access the endpoint to query your data.

Create a DynamoDB table named customers by using a numeric primary key (customer ID) that never changes, apply default settings, and launch the table for use; next lecture covers ElastiCache.

Learn to deploy, operate, and scale an in-memory cache with Amazon ElastiCache, configuring cache subnet groups, VPC, security groups, and Memcached or Redis clusters across availability zones.

AWS offers five database options, including RDS, DynamoDB, ElastiCache, Redshift, and the Database Migration Service, enabling patching, backups, low-latency performance, data warehousing, and zero-downtime migrations.
