Shared Responsibility Model
Notes: Domain 1.1-1.3
-AWS allows for sufficient compute, memory, network, and storage resources. Global infrastructure is also efficient |
-Lots of redundancy so that if one part fails, there is always a failover |
-Allocation of resources is automated via the metered pay model |
-CapEx (Capital Expenses) relates to on-prem solutions and hardware. Cloud solutions do not have any CapEx. |
-Server virtualization. VMs are created and access storage/computing resources from the host server. Virtualization offers two main benefits: Speed/Efficiency |
-located in a physical server: Compute to Storage to Hypervisor (VM Admin Software) to the virtual machine. Storage is attached to it |
-On prem, IaaS, PaaS, Saas |
-Serverless workloads allow for users to run on cloud servers. Provided by AWS Lambda servervices, makes code that is REACTIONARY. |
-Scalability allows apps to grow automatically based on organizational needs |
-Elasticity matches compute power w/ rising and falling demand. Ex: AWS Auto Scaling. Will operate within its limits |
Chapter 2 Notes: Domain 4.1-4.3
Free Tier |
Can run for up to 750 hrs per month using a t2.micro EC2 instance. Can be used to run light relational database workloads with Amazin Relational Database Services (RDS).

| |
Permanently Free:10 monitoring metircs/alarms on Amazon CloudWatch, 62000 outbound emails/month w/ SES, 3.2 million seconds of compute time, one million requests w/ Lambda |
Budgeting |
Rates change with how much storage is needed, pricing varies by regions. For EC2, you can choose between pricing types (on-demand, spot, savings,reserve instances, dedicated host pricing) |
| |
Can use AWS pricing calculator for estimating cost. 2 main benefits: pricing is real time and can visualize the impacts of each element fiscally |
| |
Can utilize the billing dashboard, can create one of three budget types: Usage Budgets, cost budgets, reservation instance or coverage budget, or savings plan coverage |
| |
Other tools: Cost explorer (visualizes account's historical usage), Cost/usage reports (show full range of activity), Cost allocation tags (resource tags, cost allocation tags), and AWS Organizations (centralizes admin of multiple AWS accounts for allocation) |
Service Limits |
Can only launch 20 reserved instances within EC2 each month so all classes of resources are reliable. Limits are adjustable |
Resource requests can be refused.
