Dedicated hosting provides your website an entire system, offering greater power and control at higher cost, with linux plans such as 512gb storage, 2gb ram, 5 tb bandwidth, and administration.

Explore how cloud hosting provides scalable, utility-based pricing and access to global data centers, enabling on-demand virtual machines for CPU, RAM, storage, and bandwidth, contrasting with traditional hosting limits.

Registering a domain name creates a unique web address. You can host via IP, while ICANN coordinates registrars and registries to manage domains like .com and ccTLDs such as .jp.

Choose a reputable domain registrar that provides domain security, administration through an online portal, and brand protection services, as these shape your website's future value and safety.

Cloud computing provides on-demand, pay-as-you-go resources like servers, storage, databases, networking, and analytics. Virtualization enables virtual instances via a hardware abstraction layer and hypervisors, provisioning CPU, memory, storage, and networking.

Discover how cloud computing delivers cost efficiency, agility, scalability, reliability, and security through on-demand resources, rapid deployment of virtual instances, global data centers, and a shared responsibility model.

Explore the three cloud service models, IaaS, PaaS, and SaaS, and compare them with on-premises setups, highlighting pay-as-you-go resource provisioning through a cloud provider.

Explore infrastructure as a service (IaaS), offering scalable on demand compute, storage, and network resources managed by a cloud provider with virtualization and rapid deployment for use cases like e-commerce.

Platform as a service (PaaS) provides a cloud platform where providers manage software and infrastructure for scalable, rapid deployment, enabling DevOps collaboration and data analytics with IoT support.

explore software as a service (saas), a cloud hosted, subscription-based model delivering apps via web browsers or mobile apps. learn how vendors manage infrastructure, data storage, upgrades, and security.

Compare IaaS, PaaS, and SaaS across on-premises data centers to cloud models, noting control, cost, and vendor responsibility, while market share trends hint at future growth.

Learn how to set up a Linode account on the Linode cloud platform by signing up, confirming email, entering billing and payment details, and agreeing to the master services agreement.

Explore the Linode cloud manager dashboard, access volumes, block storage, and object storage, review the marketplace and account settings, and learn about learning aids and support resources.

Enable two-factor authentication on your Linode account to secure access using knowledge and possession components. Set up Google Authenticator, scan the QR code, save the scratch code, and test login.

Deploy and configure a Linode virtual instance with Ubuntu 20.04 LTS in Newark, New Jersey, choosing a plan and resources (RAM, CPU, storage, bandwidth) and setting a strong root password.

Explore the Linode instance dashboard to monitor a test VM, view analytics, manage networks and volumes, and access SSH commands for remote administration.

Learn secure methods to connect to a Linode instance for administration, including updating OS, installing software and patches, managing files, monitoring performance, and configuring firewalls via the command line.

Discover how SSH key authentication strengthens security by replacing passwords with a private key and public key pair, using OpenSSH tools, and understanding the transport, authentication, and connection layers.

Learn to generate a 4096-bit ssh key pair on Windows with PuTTY Gen, upload the public key to a Linode server, and enable ssh key authentication using PuTTY.

Generate an ssh key pair on macOS using terminal with 4096-bit keys and a passphrase, then securely copy the public key to your Linode instance to enable ssh key authentication.

Remotely connect to your Linode instance via the web-based lish console in the cloud manager, log in as root, and run terminal commands.

Learn to add an ssh public key to your Linode account for future instance deployments, including labeling keys, pasting the public key, and enabling them during deployment.

Explore the exponential growth of cloud computing, AWS's dominance, and global market trends. Understand adoption rates, workload shifts to public and hybrid clouds, and barriers like privacy, security, and training.

Explore the origins and rapid growth of AWS within Amazon, from EC2, SQS, and S3 to Prime and enterprise adoption, with milestones in certifications and AI services.

Explore how AWS dominates the cloud market with 41.5% share, 1 million customers, 175 services, and global data centers, while pricing trends and the AWS Partner Network drive broad adoption.

Gain confidence navigating the AWS console and understanding the pay-per-use billing model across global and regional services. Build a foundation in AWS budgeting and security to prevent unauthorized use.

Explore how AWS pricing works, including pay-per-use billing, resource-based costs, volume discounts, tiered pricing for S3, and reserved instances with upfront or no upfront payments to save on EC2 costs.

Discover how the AWS free tier provides 750 hours of EC2 usage, free S3 storage, EFS, and EBS options, with billing alerts to avoid overage.

Review AWS acceptable use policy to understand prohibited actions, consequences like suspension or termination, and the importance of compliance with legal agreements and the privacy policy.

Register an AWS account using the free tier and complete billing verification to access the AWS management console. Learn to navigate services, regions, and essential account details.

Explore core AWS services for the cloud practitioner exam, including IAM, compute (EC2, ECS, Lambda), storage (S3, EBS, EFS), networking (VPC), databases, monitoring (CloudWatch, CloudTrail), and security.

Compare global and regional AWS services, explore regions and availability zones, and understand how local zones enhance proximity and low-latency, highly available deployments.

Explore the difference between global and regional cloud services with an AWS case study, illustrating IAM as global, EC2 regional, S3 regional, and Route 53 and CloudFront global.
