AWS Cloud First Recap

AWS (Amazon Web Services):

• AWS is a cloud computing platform provided by Amazon. It offers a wide range of services, including computing power, storage, databases, machine learning, analytics, and more.

Cloud Computing Models:

• Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet, such as virtual machines, storage, and networking (e.g., Amazon EC2).
• Platform as a Service (PaaS): Offers a platform that includes runtime, development, and deployment services, eliminating the need to manage underlying infrastructure (e.g., AWS Elastic Beanstalk).
• Software as a Service (SaaS): Delivers software applications over the internet without the need for users to install, manage, and maintain the application (e.g., Amazon WorkMail).

AWS Global Infrastructure:

• AWS operates in multiple geographic regions worldwide, each with multiple availability zones. This provides redundancy, fault tolerance, and low-latency access to AWS services.

AWS Core Services:

• Compute: Amazon EC2 (virtual servers), AWS Lambda (serverless compute), AWS Elastic Beanstalk (PaaS).
• Storage: Amazon S3 (object storage), Amazon EBS (block storage), Amazon Glacier (cold storage).
• Databases: Amazon RDS (managed relational databases), Amazon DynamoDB (NoSQL), Amazon Redshift (data warehousing).
• Networking: Amazon VPC (Virtual Private Cloud), Elastic Load Balancing, Amazon Route 53 (DNS).

Identity and Access Management (IAM):

• IAM is used to manage access to AWS services securely. It allows you to create and manage AWS users and groups, assign policies, and control permissions.

Security and Compliance:

• AWS provides a robust set of security features, including encryption, identity management, monitoring, and compliance certifications. Customers are responsible for securing their own content and applications.

AWS Management Console:

• The AWS Management Console is a web-based interface that allows users to access and manage AWS services. It provides a visual way to interact with various AWS resources.

AWS Marketplace:

• The AWS Marketplace is a digital catalog where customers can find, buy, and deploy software and services directly from AWS partners.

AWS Well-Architected Framework:

• A set of best practices and guidelines for building secure, high-performing, resilient, and efficient infrastructure on AWS.

Serverless Computing:

• AWS offers serverless computing options such as AWS Lambda, allowing developers to run code without provisioning or managing servers.

Containerization:

• AWS provides services like Amazon ECS (Elastic Container Service) and Amazon EKS (Elastic Kubernetes Service) for managing and orchestrating containerized applications.

AI and Machine Learning:

• AWS offers services like Amazon SageMaker for machine learning, Amazon Polly for text-to-speech, and Amazon Rekognition for image and video analysis.
