Study Notes
- Cloud computing involves renting computing resources over the internet on a pay-per-use basis.
- Amazon Web Services (AWS) manages data centers globally, offering various services.
Traditional Computing vs. Cloud Computing
- Traditional computing relies on physical hardware, incurring high upfront costs and requiring space, security, and staff. Buying and setting up servers takes time.
- Estimating future needs is necessary, and overestimation leads to wasted resources, while underestimation results in insufficient capacity.
- Modifying the setup is slow and costly.
- Cloud computing treats infrastructure like software, providing flexibility and easy adjustments.
- Users can add or remove resources as needed and pay only for their actual usage.
- Businesses can scale quickly and inexpensively.
Cloud Computing Service Models
- IaaS (Infrastructure as a Service) provides basic IT resources like virtual machines and storage, offering the most control.
- PaaS (Platform as a Service) manages the infrastructure, allowing users to focus on application development and deployment.
- SaaS (Software as a Service) provides ready-to-use software managed by the provider.
Cloud Computing Deployment Models
- Cloud deployment means the entire application runs in the cloud.
- Hybrid deployment uses a mix of cloud and on-premises resources.
- On-Premises (Private Cloud) deployment hosts resources locally, offering control but lacking many cloud benefits.
AWS Services
- AWS offers services mirroring traditional IT resources, facilitating the transition to the cloud:
- AWS security groups, network ACLs, and IAM are like firewalls, access control lists, and administrators.
- Elastic Load Balancing and Amazon VPC function like routers, network pipelines, and switches.
- Amazon Machine Images (AMIs) and EC2 instances are like on-premises servers.
- AWS storage services (EBS, EFS, S3, RDS) are similar to direct attached storage, SAN, NAS, and RDBMS.
- AWS replicates tasks from traditional data centers with enhanced flexibility and scalability.
Advantages of Cloud Computing
- Trade Capital Expense for Variable Expense: Pay only for what is used, saving money and reducing maintenance efforts.
- Benefit from Massive Economies of Scale: Lower prices by sharing resources with many users.
- Stop Guessing Capacity: Easily scale up or down based on demand, avoiding waste or shortage.
- Increase Speed and Agility: Access resources in minutes, boosting development speed.
- Stop Spending Money on Running and Maintaining Data Centers: Focus on business growth, not server maintenance.
- Go Global in Minutes: Easily deploy worldwide for better customer experiences with minimal cost.
Web Services
- Web service is software accessed over the internet or a private network.
- It communicates between applications using XML or JSON via an API.
- Web services are independent of operating systems and programming languages.
Amazon Web Services (AWS)
- AWS is a secure cloud platform with on-demand IT resources.
- Resources can be provisioned in minutes and adjusted as needed.
- Key benefits include flexibility, cost efficiency, and integration.
- AWS services work together to create scalable solutions.
AWS Compute Services
- Amazon EC2 gives full control over virtual servers.
- AWS Lambda runs code without managing servers.
- AWS Elastic Beanstalk automatically deploys and scales web apps.
- Amazon LightSail offers simple cloud hosting for small applications.
- AWS Batch runs large-scale batch workloads.
- AWS Outposts uses AWS infrastructure on-premises.
- Amazon ECS / EKS / AWS Fargate handles container management and orchestration.
- VMware Cloud on AWS migrates on-premises virtualized environments to AWS.
Key AWS Service Categories
- Compute: Amazon EC2, AWS Lambda, Amazon ECS, Amazon EKS
- Storage: Amazon S3, Amazon EBS, Amazon EFS
- Database: Amazon RDS, Amazon DynamoDB
- Networking & Content Delivery: Amazon VPC, AWS CloudFront
- Security & Identity: AWS IAM, AWS KMS
- Management & Governance: AWS CloudWatch, AWS Config
- Cost Management: AWS Cost Explorer
- These services help build, secure, and manage applications in the cloud.
Ways to Access AWS Services
- AWS Management Console is a graphical interface.
- AWS Command Line Interface (CLI) is a command-based tool.
- AWS SDKs are libraries for programming languages to integrate AWS.
- All options use AWS’s underlying API for automation.
AWS Cloud Adoption Framework (AWS CAF)
- Cloud adoption success depends on aligning people, process, and technology.
- AWS CAF helps identify gaps, provides best practices, and organizes guidance into six perspectives.
- It focuses on capabilities to ensure a smooth transition.
AWS CAF Perspectives
- Business: Align cloud with business goals.
- People: Develop cloud skills.
- Governance: Ensure policies and compliance.
- Platform: Manage cloud infrastructure.
- Security: Protect data and resources.
- Operations: Manage day-to-day cloud activities.
Stakeholders and AWS CAF
- Business perspective stakeholders build a business case and prioritize initiatives.
- People perspective stakeholders assess structure, identify gaps, and prioritize training.
- Governance perspective stakeholders align IT and business strategies, maximize value, and minimize risks.
- Platform perspective stakeholders improve IT systems and apply AWS CAF principles.
