Understanding Of AWS
AWS (Amazon Web Services) is a comprehensive and developing cloud computing platform that combines infrastructure as a service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS) solutions to provide services in the form of building blocks.
These components or services are intended to help enterprises collaborate, develop, and deploy sophisticated and highly scalable applications to increase their performance and efficiency.
Depending on where you are located, it provides greater security and storage flexibility, increased computational capacity, easy database development, and even content caching.
AWS is not constrained by geography or time zones.
It offers over 175 fully-featured services from its data centres distributed internationally over 76 availability zones, covering a total of 245 nations.
The applications are dependable since they run on an AWS infrastructure that is safe and secure.
- Scalability and Elasticity
Businesses benefit from AWS’s on-demand infrastructure because it gives them more scalability, allowing them to innovate and experiment more quickly.
These 175 cloud services are scalable and available on a pay-as-you-go basis. This means you only pay for the services you use, and the less you use them, the less you pay. This also means that the more you use it, the lower your per-unit cost. (i.e., with each new purchase, each unit costs less)
AWS is platform agnostic to operating systems and languages, with no hard protocols or constraints. It gives organizations the flexibility to choose the programming style or development platform that best suits their needs.

Products For AWS Data Transfer
The primary data migration, collecting, and data transfer tools that help in seamless data gathering are Amazon Relational Database Service (Amazon RDS), which comprises Amazon Aurora, Amazon DynamoDB Accelerator, and Amazon RedShift. AWS users can also use these products to monitor and analyze data in real-time.
Elastic Compute Cloud
This service delivers EC2 instances, virtual servers that provide AWS users with safe and scalable computing capacity based on their demands. EC2 is a cloud computing platform that aims to make web-scale cloud computing more accessible.
SNS On Amazon (Simple Notification Services)
This notification tool sends messages to many subscribers via email or SMS by delivering/publishing or pushing them out.
Amazon KMS (Key Management Service)
Amazon KMS is a security solution that protects data from hackers and cyber-attacks by encrypting it with 256-bit encryption.
This low-cost service runs a code triggered by specified events and controls the resources that are reliant on it. It enables serverless computing, with payment based on how long the AWS customer takes to execute the code.
Route 53 On Amazon
This is a cloud-based Domain Name System web service that eliminates the need for AWS users to maintain a separate DNS account. Its purpose is to allow organizations to reliably and cost-effectively route consumers to internet services.

HTTP, VPN, DNS, CDN, and TCP/IP are all networking terminology that an AWS architect or developer must be aware of and understand. An AWS expert should also be familiar with services such as Route 53 (DNS), Virtual Private Cloud (VPC), and CloudFront (CDN), which are used to create cloud networking, including public and private subnets, VPC peering, and internet access.
AWS is a highly secure environment, with services and policies to ensure that only authorized users can execute certain tasks. An AWS expert must know IAM and how to safeguard networks using Security Groups and Access Control Lists.
AWS Service Selection
SQS (simple queuing), RDS (Relational Database Service), and SNS (Simple Notification Service) are three basic AWS services that every architect should be familiar with (notifications).
Knowledge of AWS IoT services can also be beneficial.
Cloud Specific Technologies
Knowledge of numerous AWS core services, such as AWS Lambda, EC2, S3, VPC, ELB, and others, is required to properly design workloads and harness AWS infrastructure to create scalable and available applications.
