• Easy to Use: AWS services are easy to use and implement, as they provide specific tools and APIs for better management. This saves time and various other resources.
• Trusted Cloud Infrastructure: AWS is the industry leader in terms of security and global data centers. It is a powerful, versatile, scalable, and cost-effective cloud platform, making it a popular choice for all types of businesses and giving it a global reach.
• Broad Ecosystem of Tools: Whether you’re using databases or working on user authentication systems, AWS offers everything you need under one roof. AWS also continuously updates and adds new services to stay at the forefront of technology.

Top 10 AWS Services Every Scalable App Needs

Below is a list of AWS services that have the greatest impact on early-stage applications, along with practical tips and common pitfalls to avoid.

1. Amazon EC2 (Elastic Compute Cloud)

EC2 stands for Elastic Compute Cloud, which is a virtual server for running applications in the cloud. It is a web service that lets you rent virtual computers, called instances. These instances act like servers and can be used to run your applications. Whether you have a simple project or a complex one, EC2 allows you to adjust your resources as needed, thanks to its scalable and secure computing capacity. It also supports customizable compute resources for hosting web applications, APIs, or other background tasks.

2. Amazon S3 (Simple Storage Service)

It is called Simple Storage Service and is part of Amazon Web Services. It provides cloud storage for files, images, and static content. Similar to storing files in folders, it is an object storage service that stores data as objects in buckets. Along with being scalable, secure, and high-performance, it also ensures online backup, archiving, and data storage.

3. AWS Lambda 

It is an AWS service that is serverless and event-driven. It allows developers to run code without managing servers. It uses Identity and Access Management (IAM) roles to grant permissions for sending logs to Amazon CloudWatch and updating trace data. It also enables the execution of functions in response to various events without worrying about the underlying infrastructure. Its lightweight features and scalable functionality make it ideal for microservices or MVPs.

4. Amazon RDS (Relational Database Service)

Stands for Relational Database Service. It simplifies database systems like PostgreSQL, MySQL, and many others. It’s a secure database service that provides access without the hassle of server maintenance. It helps simplify the process of setting up, operating, and scaling databases in the AWS cloud. Users can focus on their applications without worrying about data security. Its cost-efficient features and resizable capacity make it ideal for various administration tasks.

5. Amazon DynamoDB

DynamoDB is a serverless service that manages NoSQL databases optimized for low-latency performance, provided by AWS. It’s designed for high performance and scalability, helping developers build various customized applications with ease. Often, marketing and advertising professionals choose DynamoDB for its security and better performance. It helps customers achieve data accuracy by storing various marketing data such as user profiles, clicks, visited links, events, etc. DynamoDB supports key-value and document data models and can handle large volumes of data traffic. When comparing RDS and DynamoDB, RDS is a relational database, whereas DynamoDB is non-relational. RDS is more expensive than DynamoDB but offers more flexible features.

6. Amazon CloudFront

Amazon CloudFront is a CDN service, i.e., a content delivery network that helps deliver content to users with low latency and high transfer speeds. It uses a global network of servers (edge locations) to cache content closer to users, speeding up website access, video streaming, and downloading of large files. Video streaming, API, and application delivery are also supported by CloudFront. It is designed to securely deliver data at a global scale. CloudFront helps speed up app performance for global users and reduces server load. It has native features that support building, testing, and deploying your code. CloudFront intercepts requests and responses and passes them to your functions.

7. AWS Cognito

Cognito helps simplify the process of managing user identities and access controls. This service adds user sign-in, sign-up, and other access controls in web and mobile applications for authentication and authorization. It is developer-centric and cost-effective, providing secure and federated options that help millions of users. Cognito also uses AWS Lambda functions to authenticate users and assist in handling custom challenges.

8. AWS CloudFormation

This service enables users to create their AWS infrastructure as code. It helps in management, deployment, and resource provisioning by using templates in JSON or YAML format. It allows managing resources as a single unit called a stack. With this advanced service provided by AWS, users can focus on development and other tasks instead of spending time managing resources. It reduces human error during deployment and ensures consistency across environments. If you want to define your infrastructure as code alongside your application code, CloudFormation is the best fit for it.

9. Amazon CloudWatch

CloudWatch is a monitoring tool that helps manage services by providing data and insights for AWS, hybrid, and other cloud applications. It responds to performance changes, optimizes resource use, and more. It provides real-time insights into performance and availability. It helps collect and track visual metrics and logs, enabling better understanding of the performance and health of your infrastructure.

10. AWS CodePipeline

CI/CD, which stands for continuous integration and continuous delivery/deployment, aims to streamline software development cycles and accelerate them in the correct format. AWS CodePipeline is a fully managed continuous delivery service that automates the software release process and provides reliable updates to AWS infrastructure. It follows a procedure that includes building, testing code, deploying to multiple environments, and finally releasing to production. Its main use is to automate the deployment of various microservices, frontend single-page applications, or infrastructure updates. AWS CodePipeline offers a free tier, which includes one free active pipeline per month for V1 pipelines and 100 free action execution minutes per month for V2 pipelines.
