What is AWS?

Amazon Web Services (AWS) is a subsidiary of Amazon that provides on-demand cloud computing platforms and APIs to individuals, companies, and governments. Launched in 2006, AWS has grown to become the largest cloud service provider in the world, offering over 200 fully featured services, including computing power, storage options, and networking capabilities.

AWS enables businesses to run applications and store data in the cloud rather than on local servers, allowing for greater flexibility, scalability, and cost savings. With a global presence, AWS serves millions of active customers across various industries, from startups to large enterprises.

How AWS Works?

AWS Global Infrastructure:

AWS operates on a global scale, with data centers strategically located around the world. This global infrastructure consists of:

• Regions: AWS has multiple geographic regions, each containing several data centers. Each region is isolated from others to provide redundancy and fault tolerance.
• Availability Zones (AZs): Each region consists of multiple Availability Zones, which are distinct data centers that offer high availability and low latency. This design allows businesses to deploy applications across multiple AZs for increased resilience.

Pricing Model:

AWS employs a pay-as-you-go pricing model, which allows users to pay only for the resources they consume. This model includes:

• On-Demand Pricing: Users can launch resources without long-term contracts, paying only for what they use.
• Reserved Instances: Businesses can reserve capacity for a one- or three-year term, providing significant savings compared to on-demand pricing.
• Spot Instances: Users can bid on unused EC2 capacity at a lower price, making it a cost-effective option for flexible workloads.

Security and Compliance:

AWS prioritizes security and compliance, offering a wide range of tools and features to protect data. Key security features include:

• Identity and Access Management (IAM): AWS IAM allows users to manage access to AWS services securely.
• Data Encryption: AWS provides options for encrypting data at rest and in transit, ensuring data protection.
• Compliance Certifications: AWS complies with various industry standards and regulations, including GDPR, HIPAA, and PCI DSS.
