AWS provides cloud computing services that users can access over the Internet. It manages large data centers containing many servers that host these cloud-based services. The document explains AWS using a single diagram comparing it to a physical network. It shows how AWS has regions, availability zones, VPCs, subnets, security groups, and other boundaries/resources that allow cloud services like EC2, S3, and ELB to operate based on the core concepts of availability, scalability, elasticity, and fault tolerance. Key security features like ACLs and security groups control access within the AWS network boundaries.
AWS Overview in a Single Diagram
- 1. AWS Overview in a Single Diagram AWS in a nutshell for cloud newbies Authored By: Ralph Plazo
- 2. AWS Overview Diving in to learn about AWS, but still not sure about what Cloud is about? I’ll explain it to you in a single diagram coming from a context you are already familiar of. I’m hopeful that you’ll get insights to help your approach in learning AWS.
- 3. First things first... What is Cloud? ● Put it this way, “Cloud” is a computer that you access via the Internet and utilized in some capacity. ● Known “Cloud” service you access to; Gmail, Google Drive, Yahoo website, etc.
- 4. First things first... What is Cloud? ● Many of these “Cloud” services are residing not only on a single computer but a collection of servers that are located in many data centers. What is AWS? ● Is one of many “Cloud” service provider (others like Azure, Google Cloud, Alibaba Cloud). ● They managed these data center of servers that provides “Cloud” servers.
- 5. Putting things in context... How “Cloud” works? ● Many of us unaware that we are using many cloud based services on a daily basis and almost in every devices that we use. ● Just like accessing our mobile apps and websites via web browser, we are basically using some sort of cloud service.

- 6. 4 Pillars of Cloud Technology These are concepts that are embedded in the solutions that are available in Cloud Technology. Always keeps these concepts in mind to fully understand the overview and functionalities of features available in AWS.
- 7. High Availability Refers to concept of being accessible whenever and wherever you need. Scalability Ability to grow in size, capacity, and/or scope based on demand. Elasticity Ability to reduce in size, capacity, and/or scope when required. Fault Tolerance Ability to withstand a certain amount of failure and still remain functional. 11.01.XX

- 10. Concepts AWS Infrastructure ● It comprises of AWS Region which are located in different countries worldwide. Each Region has a number of Availability Zones in which AWS physical data centers are located. Virtual Private Cloud ● Similar to your physical office network, VPC is a logical isolated section of AWS where you have complete control over your virtual network environment including AWS resources (i.e. Route 53, ELB, EC2, S3) you deploy.
- 11. Concepts AWS Resources ● Similar to physical servers that servers different function in our office network; AWS Resources are virtualized services that can be easily deployed within VPC to serve different purposes. Image taken from linuxacademy.com
- 12. Understanding the AWS Boundaries Because AWS works similar to a physical data center or office network, it’s important to understand the boundaries of its features and the rest are just the services (i.e. EC2, S3, RDS, SNS, CloudWatch, etc.) that works within those boundaries.

- 14. Key Points To Note Security Features ● Both ACL and Security Groups are boundaries that provides certain level of security for AWS resources. AWS Boundaries ● AWS Region, AWS Availability Zone, VPC, Subnet, and even Auto- Scaling Groups can be considered boundaries where AWS resources (i.e. EC2, S3, RDS, etc) are encapsulated. They are also the foundation of AWS 4 core concepts.
