AWS provides secure, resilient, high-performance infrastructure to enable virtually any workload.

AWS offers a wide range of cloud computing services that provide companies with the building blocks they need to run their applications and workloads in the cloud.

IaaS Services

Popular IaaS services on AWS include:

EC2 (Elastic Compute Cloud)

Provides secure, resizable compute capacity in the cloud. It allows customers to launch virtual server instances on demand to meet changing needs.

Customers pay only for the capacity used without upfront costs or long-term commitments.

VPC (Virtual Private Cloud)

This gives customers control over the virtual networking environment.

Storage Services 

AWS offers reliable, scalable, and inexpensive data storage options:

S3 (Simple Storage Service)

Provides developers and IT teams with secure, durable, and highly scalable object storage. 

The web service interface allows storing and retrieving any amount of data from anywhere on the web.

EBS (Elastic Block Store)

Provides persistent block-level storage volumes for EC2 instances.

It allows attaching a storage volume to a single EC2 instance and persisting data beyond the lifetime of that instance.

Database Services

RDS (Relational Database Service)

This removes the administrative burden of managing databases.

DynamoDB

Networking and Content Delivery

AWS offers networking services like VPC for isolating cloud resources and content delivery solutions: 

CloudFront

This provides low latency and high data transfer speeds.

The wide range of AWS cloud infrastructure and application services provide building blocks that power modern cloud-native and legacy applications.

The services offer flexibility, scalability, and reliability.

AWS offers a wide range of platform services that enable developers to quickly build, deploy, scale, and manage applications without worrying about the infrastructure.

Serverless Compute with AWS Lambda

Key features of Lambda include:

• Allows to run code without provisioning servers
• Scales automatically from a few requests per day to thousands per second
• Pay only for the compute time consumed - no charge when code is not running
• Integrates with other AWS services and supports multiple languages like Node.js, Python, Java, etc.

Using Lambda frees developers from operational tasks so they can focus on writing code.

It's a cost-effective way to build applications that respond quickly to new information.

Containers Services – ECS and EKS

AWS offers two services for running containerized applications:

• Amazon Elastic Container Service (ECS) – Highly scalable container orchestration service that supports Docker containers
• Amazon Elastic Kubernetes Service (EKS) – Fully managed Kubernetes service for deploying and managing containers 

Both ECS and EKS make it easy to run distributed applications in the AWS cloud without managing servers or clusters.

Developers can easily deploy and move containers between environments which improves developer productivity and application portability.

AWS Elastic Beanstalk and AWS CloudFormation

Additional platform services include:

Beanstalk allows deploying applications quickly without infrastructure management. 

CloudFormation enables using code to manage the full lifecycle of the infrastructure related to applications in a structured way.

AWS employs a shared responsibility model for security and compliance.

AWS manages the security of the cloud, while customers are responsible for security in the cloud.

Shared Responsibility Model

The shared responsibility model outlines what AWS and customers are each responsible for when it comes to security and compliance.

AWS is responsible for protecting the global infrastructure including hardware, software, networking, and facilities.

Customers are responsible for securing their data, platform, applications, and identities.

But ultimately customers must configure their environments properly and manage security to meet their compliance needs.

Identity and Access Management (IAM)

With IAM you can create users, groups, roles, and policies to allocate permissions and grant the appropriate access.

IAM enables you to implement least privilege access to your account and resources.

Compliance with Regulations

AWS keeps audit records and obtains third-party audits and certifications to meet compliance standards like SOC, PCI DSS, FedRAMP, and HIPAA.

Customers can build compliant applications on top of AWS’s compliant foundation.

AWS provides resources to demonstrate compliance and gives customers access to AWS security controls and compliance reports.

Customers can establish governance models, controls, processes, and auditing aligned to internal guidelines or external regulations.

AWS provides a suite of tools to manage your cloud resources and optimize their usage. 

These tools give visibility into your infrastructure and help track costs and usage.

Monitoring with CloudWatch

Key features of CloudWatch include

• Metrics - Get system-wide visibility with metrics for CPU, network, disk utilization, etc. Set alarms to notify if thresholds are crossed.
• Logs - Aggregate, monitor, and analyze log files. Set up real-time processing of application and system logs.
• Events - Respond to state changes in your resources to trigger notifications, auto-scaling, and Lambda functions.
• Dashboards - Create custom dashboards to track the metrics and logs you care about from all your AWS resources.

With CloudWatch you get a unified view to monitor all your infrastructure and gain operational insight.

Logging with CloudTrail

It logs API calls made by or on behalf of your AWS account and delivers log files to you.

Key features include

• Record AWS Management Console, AWS SDK, command line tool, and other AWS service requests.
• Identify users and AWS accounts that are called an AWS service, source IP address, etc.
• Deliver log files to the S3 bucket for analysis.
• Integrate with CloudWatch logs and Lambda for custom processing.
• Meet compliance needs with comprehensive activity logging across your AWS infrastructure.

CloudTrail gives you visibility into user activity and helps meet regulatory and compliance needs.

Cost Tracking with Cost Explorer

Key capabilities

• Get visibility into your usage patterns and spend distribution.
• Forecast usage up to 12 months to better plan budgets.
• Identify opportunities to reduce costs like unused resources, AWS Savings Plans, etc.
• Analyze costs by service, usage type, region, availability zone, etc. 
• Schedule custom reports and get recommendations for cost optimizations.

With Cost Explorer, you get granular visibility into usage and costs to better manage your cloud spend.

The AWS management tools provide a unified control plane across your infrastructure to manage operational complexity.

They give you analytics and intelligence to optimize performance and costs.

This includes things like 750 hours per month of Linux/Unix t2.micro EC2 instances and 5GB of S3 standard storage.

While useful for trying things out, most real workloads will incur costs.

Billing and Budgeting

AWS has granular billing - you only pay for the exact resources you provision and use per second.

AWS also lets you set up budgets to monitor costs against business constraints.

Some best practices are enabling cost exploration, consolidating unused resources, right-sizing instances, etc.

Technical Support Plans

Basic provides customer service for account and billing questions whereas Developer adds technical support for IaaS and PaaS services.

A business plan provides 24x7 access to cloud support engineers via email, chat, and phone for faster responses.

Enterprise plan gives you an assigned technical account manager for the most mission-critical production workloads.

In summary, AWS provides a layered set of cost management tools, billing services, and technical support tailored to various customer needs.
