While AWS is designed to be user-friendly, the vast array of services can be overwhelming, especially for new users. This is where an AWS cheat sheet comes in handy.
In this article, we will provide you with an AWS cheat sheet that covers the most essential AWS services, their descriptions, use cases, and tips and tricks for mastering them. Whether you’re an experienced AWS user or a newbie, this cheat sheet will help you optimize your AWS experience and improve your productivity.
Essential AWS Services
AWS offers over 175 services across different categories, including compute, storage, databases, networking, security, machine learning, analytics, and more. However, not all services are equally important for all users. Here are some of the most essential AWS services that you should know:
1 - Compute Services
EC2 (Elastic Compute Cloud)
EC2 is one of the foundational AWS services, offering scalable computing resources in the cloud. EC2 allows users to launch virtual machines (EC2 instances) in the cloud and configure them based on their needs. EC2 is highly flexible and can be used for a wide range of use cases, from web hosting to machine learning and big data processing.
Lambda is a serverless compute service that allows users to run code without provisioning or managing servers. With Lambda, users can upload their code (in various programming languages), specify the triggers that should activate the code (e.g., a new file uploaded to S3), and pay only for the compute time that their code consumes.
2 - Storage Services
S3 (Simple Storage Service)
S3 is a highly scalable and durable object storage service that allows users to store and retrieve any amount of data in the cloud. S3 is highly flexible and can be used for a wide range of use cases, from storing and serving static web content to backing up data and hosting data lakes.
EBS (Elastic Block Store)
EBS is a block-level storage service that provides persistent block storage volumes for EC2 instances. EBS volumes can be attached to EC2 instances and used as primary or secondary storage. EBS volumes are highly available and durable, and can be used for a wide range of use cases, from running databases to storing and serving data-intensive applications.
3 - Database Services
RDS (Relational Database Service)
RDS is a managed database service that allows users to set up, operate, and scale relational databases in the cloud. RDS supports several popular database engines, including MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. RDS is highly scalable, available, and secure, and can be used for a wide range of use cases, from web applications to enterprise applications.
DynamoDB is a NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB is highly flexible and can be used for a wide range of use cases, from gaming and ad tech to IoT and mobile apps. DynamoDB is fully managed and can automatically scale up or down based on your application's demand.
4 - Networking Services
VPC (Virtual Private Cloud)
VPC is a networking service that allows users to create isolated virtual networks in the cloud. VPC provides several networking components, including subnets, route tables, and security groups, that enable users to control their network traffic and security. VPC is highly scalable, available, and secure, and can be used for a wide range of use cases, from running web applications to deploying hybrid architectures.
Route 53 is a scalable and highly available Domain Name System (DNS) service that can be used to route users to internet applications. Route 53 can also be used to route users to internal resources, such as Amazon EC2 instances or Elastic Load Balancers, within your VPC. With Route 53, users can manage their domain names, monitor their resources, and use several advanced routing policies to improve the performance and availability of their applications.
Direct Connect is a dedicated network connection service that allows users to establish a private and secure connection between their data center and AWS. Direct Connect can help users reduce their network costs, increase their bandwidth throughput, and improve their network performance and security. With Direct Connect, users can extend their on-premises infrastructure to the cloud, and deploy hybrid architectures that combine the benefits of both environments.
5 - Security Services
IAM (Identity and Access Management)
IAM is a security service that enables users to manage access to their AWS resources. With IAM, users can create and manage users, groups, and roles, and define fine-grained permissions for each resource. IAM provides a central point of control for access management and can help improve the security of your AWS environment.
KMS (Key Management Service)
KMS is a managed encryption service that allows users to create and control the encryption keys used to protect their data in AWS. KMS provides a secure and scalable way to manage your keys, and integrates seamlessly with other AWS services, such as S3 and EBS. KMS can help you meet regulatory and compliance requirements, and improve the security of your data.
6 - Machine Learning Services
SageMaker is a fully-managed machine learning service that allows users to build, train, and deploy machine learning models at scale. With SageMaker, users can choose from several popular machine learning frameworks and algorithms, and use pre-built models or build their own. SageMaker also provides a set of tools and features to help users manage their entire machine learning workflow, from data labeling to model tuning and deployment.
Rekognition is a machine learning service that allows users to analyze images and videos to detect objects, faces, text, and scenes. Rekognition can also recognize celebrities and identify inappropriate content. Rekognition is highly accurate and scalable, and can be used for a wide range of use cases, from security and surveillance to media and entertainment.
7 - Analytics Services
Redshift is a fully-managed data warehouse service that allows users to store and analyze data at scale. Redshift is highly scalable and can support petabyte-scale data warehouses. Redshift also provides several advanced analytics features, including machine learning integration and query acceleration. Redshift can be used for a wide range of use cases, from business intelligence to ad hoc analysis and reporting.
Athena is a serverless interactive query service that allows users to analyze data in Amazon S3 using standard SQL. Athena is highly scalable and can analyze petabyte-scale data sets in seconds. Athena also provides several advanced features, including federated queries and machine learning integration. Athena can be used for a wide range of use cases, from ad hoc analysis to big data processing and log analysis.
Tips and Tricks for Mastering AWS Services
Now that you’ve familiarized yourself with some of the essential AWS services, it’s time to take your AWS skills to the next level. In this section, we’ll provide you with some tips and tricks to help you master AWS services and optimize your AWS experience.
