Study Notes
Cloud Computing Overview
- Cloud computing is the on-demand delivery of compute power, database, storage, applications, and other IT resources via the internet with pay-as-you-go pricing.
- It enables thinking of infrastructure as software, rather than hardware.
Traditional Computing Model
- Traditional computing model requires:
- Space, staff, and physical security
- Planning and capital expenditure
- Long hardware procurement cycle
- Provisioning capacity based on guessing theoretical maximum peaks
Similarities between AWS and Traditional IT
- Security: Firewalls, ACLs, Administrators (Traditional IT) vs. Security groups, IAM (AWS)
- Networking: Router, Network pipeline, Switch (Traditional IT) vs. Elastic Load Balancing, Amazon VPC (AWS)
- Compute: On-premises servers (Traditional IT) vs. Amazon EC2, AMI, instances (AWS)
- Storage and Database: DAS, SAN, NAS, RDBMS (Traditional IT) vs. Amazon EBS, Amazon EFS, Amazon S3, Amazon RDS (AWS)
Cloud Computing Benefits
- Stop spending money on running and maintaining data centers
- Go global in minutes
- Trade capital expense for variable expense
- Benefit from massive economies of scale
- Stop guessing capacity
- Increase speed and agility
Introduction to Amazon Web Services (AWS)
- A web service is a piece of software that makes itself available over the internet and uses a standardized format (e.g. XML, JSON) for API interactions.
- AWS is a secure cloud platform that offers a broad set of global cloud-based products, providing on-demand access to compute, storage, network, database, and other IT resources and management tools.
