This AWS cheat sheet will guide you through the fundamentals of AWS, which makes it suitable for both newcomers and those wanting a quick overview. Let’s begin our discussion about cloud computing before diving deeper.

Let’s start our discussion by talking about Cloud Computing first.

Cloud Computing

Cloud Computing is an internet-based computing service in which various remote servers are networked to allow centralized data storage and online access to computer services and resources.

Watch this AWS Interview Questions video:

Types of Cloud

There are three cloud types, which are mentioned below:

Public Cloud: Here, the resources and services that are provided by third-party service providers are available to customers via the Internet.
Private Cloud: In a private cloud, the resources and services are managed in-house or by third parties exclusively for a particular organization.
Hybrid Cloud: It is a combination of public and private cloud types. The decision whether to run the services on public or private networks depends on some parameters such as the sensitivity of the data and applications, industry certifications, required standards, etc.

AWS

Amazon Web Services (AWS) provides flexible, reliable, easy-to-use and cost-effective cloud computing services and applications. AWS instances serve as virtual servers to run applications on the cloud.

Types of AWS Services

Auto Scaling: Amazon Web Services’ auto scaling provides an automated means for launching or terminating AWS EC2 instances according to user-defined policies.

Elastic Load Balancing automatically distributes application traffic among multiple instances across different availability zones.

Lambda: It is a computing service that runs the code in response to events and automatically manages the computing resources.
EC2 Container Service: It allows us to easily run and manage Docker containers across a cluster of EC2 instances.

Storage Services

S3: It stands for Simple Storage Service. S3 allows the storage of data objects of any sort, as well as flat files, in the cloud. It is secure, scalable, and durable.
CloudFront: CloudFront defines a Content Delivery Network. It provides a way to distribute content to end-users with low latency and high data transfer speeds.
Glacier: It is a low-cost storage service that provides secure and durable storage for long-term data archiving and backup.
Elastic File Storage (EFS): It is a file storage service used in EC2 instances; it connects to multiple EC2 instances.
Snowball: It is used for moving large amounts of data into/out of AWS using secure appliances, i.e., it provides data archiving functionality for data that no longer needs to be accessed actively.
Storage Gateway: AWS Storage Gateway is used for securely integrating on-premises IT environments with cloud storage for backup and disaster recovery.

Relational Database Service (RDS): It allows the storage of data objects as part of the relational database. It makes it easy to set up, operate, and scale familiar relational databases in the cloud.
DynamoDB: It is a scalable NoSQL data store that is used to manage distributed replicas of data for high availability.
ElastiCache: It improves application performance by allowing us to retrieve information from an in-memory caching system. It is a way of caching databases in the cloud.
Redshift: It is a fast, fully managed data warehousing service, which makes it cost-effective to analyze all data using the existing Business Intelligence tools.
Data Migration Service (DMS): It helps in migrating databases to the cloud easily and securely. It can also be used for converting databases.

Analytics

Amazon EMR: Amazon Elastic MapReduce (EMR) helps perform various big data tasks such as web indexing, data mining, and log file analysis.
Data Pipeline: The Data Pipeline facilitates the moving of data between services using regular, data-driven workflows.
AWS Elasticsearch is a managed service that is designed to deploy, operate, and scale Elasticsearch quickly and easily.
Kinesis allows us to easily work with real-time streaming data stored in AWS clouds.
AWS Machine Learning gives us access to advanced machine learning algorithms, so we can easily build smart applications.
QuickSight: Amazon Web Services QuickSight is a cloud-based BI tool that is designed to quickly uncover insights in data.

Security and Identity

- IAM: Amazon Web Services IAM provides security settings to ensure that our other services remain safe and inaccessible to others.
- Directory Service: The AWS Directory Service serves as a cloud directory with managed search features.
- AWS Inspector provides us with an analytical capability for the applications running on AWS and helps in identifying any security concerns.
- AWS Web Application Firewall (WAF) protects web apps against attacks by providing web traffic filters; whilst CloudHSM serves as a Hardware Security Module.
- KMS stands for Key Management Service.

Management Tools
