Study Notes

Cloud Economics

Cloud economics focuses on the financial aspects of cloud computing.
Pay-as-You-Go Model: Users pay only for the cloud resources consumed, converting capital expenditures (CapEx) to operational expenses (OpEx).
Capital Expenses (CapEx): Large upfront costs for purchasing physical infrastructure (servers, data centers). Associated with high, fixed costs regardless of usage.
Operational Expenses (OpEx): Ongoing costs related to using cloud services. Users "rent" resources and pay for their usage. Associated with costs only when resources are used.
Scalability: Adjusting resources up or down based on demand. This avoids over-provisioning and reduces costs.
Reduced Maintenance Costs: Cloud providers handle hardware maintenance, electricity, cooling and other infrastructure management tasks, saving users money.

Cost Savings of Moving to the Cloud

Eliminate Upfront Costs: Avoid purchasing and maintaining physical servers.
On-Demand Pricing: Pay only for the compute, storage, and networking resources used.
Energy Efficiency: AWS data centers are optimized for energy efficiency, lowering operating expenses.
Economies of Scale: AWS's large customer base allows for lower prices compared to maintaining a private cloud.

Fixed vs. Variable Costs

Fixed Costs (Traditional IT): Costs that remain constant regardless of usage. (e.g., servers, data centers, cooling).
Variable Costs (Cloud): Costs that change based on usage. (e.g., compute power, storage).
Cloud Advantage: Cloud shifts the cost structure from fixed to variable costs, leading to greater flexibility and cost efficiency.

On-Premises Environment Costs

Hidden Costs: On-premises environments have significant hidden costs.
Hardware Costs: Costs associated with purchasing and maintaining physical servers and storage.
Facility Costs: Data center space, electricity, and cooling systems.
IT Staff Costs: Salaries for personnel managing hardware and software.
Disaster Recovery Costs: Costs of building and maintaining backup systems for outages or failures.
Cloud Advantage: AWS services often absorb many of these on-premises costs.

Licensing Strategies

Bring Your Own License (BYOL): Utilizing pre-existing software licenses on AWS.
Included Licenses: Licenses are provided as part of the cloud service.
BYOL Considerations: BYOL can be more cost-effective if appropriate licenses already exist, while included licenses simplify management.

Rightsizing

Rightsizing: Adapting cloud resources to match precise workload needs.
Importance: Preventing over-provisioning and ensuring optimal performance at the lowest cost.
Example Tools: AWS Compute Optimizer can suggest the most appropriate instance type and size for your workload.

Benefits of Automation

Automation: Cloud automation saves time, reduces errors, and lowers costs.
AWS CloudFormation: Automates the provisioning and configuration of AWS resources. Enables application stack deployment with a single template.
Benefits: Eliminates manual errors, accelerates deployment, improves consistency.

Managed AWS Services

Managed Services: Simplify operations and free resources for innovation.
Amazon RDS: Fully-managed relational databases, handling backups, patching, and scaling.
Amazon ECS: Fully-managed service for running and scaling Docker containers.
- Fargate: Serverless option where AWS handles the infrastructure.
- EC2: More control over underlying server instances.
Amazon EKS: Managed Kubernetes service.
Amazon DynamoDB: Fully-managed NoSQL database with high performance and scalability.
Managed Service Value: Focus on innovation rather than maintenance, reduce the need for specialized skills.
