Learn how security groups act as a virtual firewall within a vpc, controlling inbound and outbound traffic for an instance with configurable rules.

Public IPs are globally routable, private IPs stay in a private network behind a gateway, and elastic IPs provide a static public IP tied to your account.

Explore how public IPs, private IPs, and elastic IPs work in AWS through hands-on exercises, learning IP association, start/stop effects, and when to use each address.

Launch and configure an EC2 Linux instance, install and start Apache, update packages, configure security group for port 80, and verify a test page via the public IP.

Configure EC2 user data to run scripts, install software via yum, and start and enable services on launch, including setting security group access for port 22.

Explore AWS instance launch types, including on-demand, reserved, spot, dedicated host, and dedicated instance, with notes on pricing, commitments, and suitable use cases.

Explore how to launch various instance types, including dedicated hosts, spot, and on-demand, with tenancy settings, placement options, and upfront or bid payment.

Launch an Amazon Linux instance, open ports 22 and 80, connect via public IP, install a web server, and create an ami to launch new instances from it.

Launch multiple ec2 instances from a single Amazon machine image, a preconfigured template that includes the operating system and software, available as private, public, or marketplace images.

Explore EC2 placement groups and learn how cluster, spread, and partition strategies govern instance placement, low latency, high bandwidth, and resilience, with hands-on console setup.

Master hands-on AWS EC2 placement groups by creating cluster, spread, and partition strategies in the AWS console to optimize instance placement and prevent EC2 instance failure.

Explore the spot instance and unused cloud capacity, achieving discounts against on-demand pricing. Discover bid-based termination, minimum one to six hours, and pools for capacity-optimized, price-optimized, and lowest-price strategies.

Learn how to deploy spot instances on AWS using the EC2 console and launch templates, selecting instance types, capacity pools, and pricing to optimize savings.

Learn to diagnose EC2 launch issues, including per-region vCPU limits, insufficient capacity, and terminations due to EBS, KMS, or AMI problems, and resolve by region or quota changes.

Troubleshoot EC2 ssh connections by resolving private key file permission errors (400), host key errors, and configure security group inbound rules to fix timeouts.

Learn how EC2 hibernate preserves in-memory RAM by saving to an encrypted EBS volume, enabling fast resumption for long-running processes, and how to configure, start, and stop hibernate.

Explore how burstable AWS instances like T2 and T3 use CPU credits to handle spikes, compare unlimited and standard credit modes, and monitor credit usage.

Connect to EC2 instances via SSH on port 22 using a private key and the default username, then explore IP options, EBS, EMI templates, and pricing models.

Discover high availability and scalability by comparing vertical scalability (scale up) with horizontal scalability (scale out), and see how load balancers and auto scaling enable fault-tolerant, multi-data-center deployments.

Explore how load balancers distribute traffic across multiple instances, perform health checks, and manage stickiness, target groups, and SSL across classic, application, and network load balancers.

Configure and test an AWS elastic load balancer demo, create instances and security groups, set up a target group and DNS access, and verify health checks and routing.

Learn how stickiness, a load balancer feature, preserves session affinity by directing a client to the same instance, with configurable timeouts and health checks.

Explore cross-zone load balancing and elastic stickiness, keeping a user on the same instance behind the load balancer, configure stickiness in console with timeouts, health checks, and target groups.

Learn how ssl certificates secure traffic with the elastic load balancer, including ssl termination, public certificates, acm options, and configuring listeners for multiple domains using sni and hostname-based routing.

Explore how to configure an auto scaling group with a load balancer and target group, using a launch template, health checks, and scalable capacity from 1 to 3.

Explore auto scaling group scaling policies, including target tracking policy, step scaling, and simple scaling, with cooldown periods, capacity adjustments, and CloudWatch alarms demonstrated in live configuration.

Explore how Amazon elastic block storage works, create and attach volumes to instances, manage root and data drives, and compare gp2, io1, throughput-optimized, cold HDD, and magnetic types.

Explore how to create and attach an EBS volume from a snapshot, select gp3 or standard types, set deletion on termination, and mount, format, and write data on Linux instance.

Learn to update and resize EBS volumes and change volume types while instances run, adjust IOPS and throughput, create snapshots and images, and move volumes and images across regions.

Explore ebs volume types, including gp2/gp3, io1, st1, and sc1, and learn how to configure size and iops for databases, streaming workloads, and big data.

Learn how to create and manage EBS snapshots as point-in-time, incremental backups stored in S3, automate with lifecycle policies, and use snapshots to create an image and copy across regions.

Learn to migrate an EBS volume between regions by creating a snapshot, building a new volume from that snapshot in the target region, and attaching it to a running instance.

Encrypt EBS volumes and snapshots by copying unencrypted items with encryption enabled using the master key, or by creating volumes from encrypted snapshots.

Explains instance store as temporary, high-throughput block storage attached to the host, contrasting with EBS. It warns of data loss when the instance ends, fixed size, and separate backup needs.

Explore how RAID combines multiple disks into logical units using striping, mirroring, and parity to boost performance and data resilience. Learn parity concepts and practical implications for storage reliability.

Explore elastic file system basics, including an NFS-based, highly available, on-demand petabyte-scale storage that auto-scales, supports mounting from multiple Linux EC2 instances, and uses security groups.

Configure and mount AWS elastic file system (EFS) with EC2 instances, choosing default or custom configurations, enabling KMS-based encryption, managing security groups, and using access points for mount points.

Contrast elastic block storage and elastic file system, showing how EBS attaches to a single instance with snapshots, while EFS is highly scalable and multi-instance.
