- How to create an AWS account
- Creating an account is the starting point to provide access to AWS services and resources. Follow these steps to set up your account:
- · Step 1: Enter your account information
- · In Root user email address, enter your email address, edit the AWS account name, and then choose Verify email address. An AWS verification email is sent to this address with a verification code.
- · Enter your Root user password and Confirm root user password, and then choose 'Continue'.
- · Step 2: Add your contact information
- · Select 'Personal' or 'Business'. Personal accounts and business accounts have the same features and functions.
- · Enter your personal or business information. For business AWS accounts, it's a best practice to enter the company phone number rather than a personal cell phone number. If you configure a root account with an individual email address or personal phone number, your account might be insecure.
- · Read and accept the AWS Customer Agreement.
- · Choose 'Continue'.
- · You receive an email to confirm that your account is created. To sign in to your new account, you can use the email address and password that you registered with. However, you can't use AWS services until you fully activate your account.
- · Step 3: Add a payment method
- · On the Billing information page, enter the information about your payment method, and then choose 'Verify' and 'Add'.
- · If you want to use a different billing address for your AWS billing information, choose 'Use a new address'. Then, choose 'Verify' and 'Continue'.
- · Step 4: Verify your phone number
- · On the Confirm your identity page, select a contact method to receive a verification code.
- · Select your phone number country or region code from the list.
- · Enter a mobile phone number where you can be reached in the next few minutes.
- · If presented with a CAPTCHA, enter the displayed code, and then submit.
- · In a few moments, an automated system contacts you. Enter the PIN that you receive, and then choose 'Continue'.
- · Step 5: Choose aws support plan
- · On the Select a support plan page, choose one of the available Support plans.
- · Step 6: Complete the sign up
- · After you choose a Support plan, a confirmation page indicates that your account is being activated. Accounts usually activate within a few minutes, but the process might take up to 24 hours.

Cloud Computing
Cloud computing provides on-demand computing resources over the internet. It allows you to access, store, and process data using remote servers rather than local hardware.
Key Concepts
Cloud Computing: Delivering computing services like servers, storage, databases, and software over the internet.
Virtualization: Technology that allows you to create virtual (rather than physical) versions of resources.
Scalability: Ability to easily scale resources up or down based on demand.
Benefits
Cost Efficiency: Pay only for what you use.
Flexibility: Scale resources as needed.
Accessibility: Access resources from anywhere with an internet connection.
Cloud Service Models
Cloud computing offers various service models, each catering to different needs and use cases. Understanding these models helps you choose the right approach for your applications and infrastructure.
Service Models
Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet, allowing you to manage virtual machines, storage, and networks.
- Example: AWS EC2 (Elastic Compute Cloud)
Platform as a Service (PaaS): Offers a platform that includes hardware and software tools over the internet, typically for application development and deployment without managing the underlying infrastructure.
- Example: Google App Engine
Software as a Service (SaaS): Delivers software applications over the internet on a subscription basis, removing the need for local installation and management.
- Example: Microsoft Office 365
Function as a Service (FaaS): A serverless computing model where you can execute code in response to events without provisioning or managing servers. This is often used for event-driven applications.
- Example: AWS Lambda
Desktop as a Service (DaaS): Provides virtual desktops hosted in the cloud, allowing users to access a desktop environment from anywhere. This model simplifies desktop management and enhances accessibility.
- Example: Amazon WorkSpaces
Database as a Service (DBaaS): Offers database management systems as a cloud service, eliminating the need to install and manage database software and hardware.
- Example: Amazon RDS (Relational Database Service)
Storage as a Service (STaaS): Provides scalable storage solutions over the internet, allowing you to store and manage data without investing in physical storage infrastructure.
- Example: AWS S3 (Simple Storage Service)
Choosing a Service Model
IaaS: Ideal for managing and customizing virtual machines, storage, and networking.
PaaS: Best for developing and deploying applications without dealing with the underlying hardware or software layers.
SaaS: Suitable for using fully developed and managed software applications directly.
FaaS: Great for executing code in response to events and automating backend processes without managing servers.
DaaS: Useful for providing remote desktop environments to users with centralized management.
DBaaS: Ideal for managing database systems without handling the complexities of database administration.
STaaS: Perfect for scalable, secure, and flexible data storage solutions.
Each service model offers different levels of control, flexibility, and management, allowing you to select the right approach based on your needs and goals.
Cloud Deployment Models
Cloud deployment models define how cloud resources are deployed and accessed.
Deployment Models
Public Cloud: Resources are owned and operated by a third-party provider and shared with other customers. Example: AWS, Azure.
Private Cloud: Resources are used exclusively by a single organization. Example: On-premises data center.
Hybrid Cloud: Combines public and private clouds, allowing data and applications to be shared between them. Example: Using AWS for public cloud and an on-premises data center for private cloud.
Use Cases
Public Cloud: Suitable for applications with varying demand.
Private Cloud: Ideal for sensitive data requiring high security.
Hybrid Cloud: Offers flexibility and scalability while maintaining security.
Benefits of Cloud Computing
Cloud computing provides numerous benefits to organizations and individuals.
Key Benefits
Cost Savings: Reduce or eliminate the need for hardware and software investments.
Scalability: Quickly scale resources up or down based on needs.
Flexibility: Access resources from any location with internet connectivity.
Disaster Recovery: Enhanced backup and recovery options.
Automatic Updates: Providers handle updates and patches for you.
Example Scenarios
Startups: Can quickly deploy applications without large capital expenditures.
Businesses: Can scale resources to handle seasonal traffic spikes.
Developers: Can focus on building applications without managing infrastructure.
