What is AWS SDK?

The AWS SDK (software development kit) simplifies the whole programming experience by providing JavaScript objects for AWS services. It enables developers to use AWS via JavaScript code that runs in the browser, and it offers access to AWS components such as Amazon S3, Amazon SNS, Amazon SQS, DynamoDB, and others.

Types of SDKs

AWS SDK for Java

The AWS SDK for Java provides access to many of the Java APIs in order to terminate coding complexities. It provides support for AWS services like  Amazon S3, Amazon EC2, Amazon DynamoDB, etc.

How it Works

As discussed earlier, AWS SDK for Java makes it easier for Java developers to access AWS Services by providing a set of libraries. It supports API lifecycle considerations such as credential management, retries, data marshaling, and serialization. For easier development, the AWS SDK for Java also offers higher-level abstractions.

AWS SDK for Java

Key Features

  • Nonblocking I/O: To allow genuine nonblocking I/O, the AWS SDK for Java 2.x makes use of a new, non-blocking SDK architecture built on Netty. It has ronblocking asynchronous clients with high concurrency across a few threads.
  • Automatic pagination: Many AWS procedures generate paginated results whenever the response object is too big to return in a single response. AWS SDK for Java 2.x employs auto pagination methods that automatically conduct numerous service calls to obtain the following results page.
  • HTTPS/2 Support and pluggable HTTP layer: New programming interfaces take full advantage of HTTP/2 features, opening up new avenues for application development.

AWS SDK for.NET also supports higher-level abstractions like the S3 Transfer Utility, Cognito Identity Provider, and AWS DynamoDB Session State provider.

AWS SDK for .Net

AWS SDK for JavaScript

Developers can use the AWS SDK for JavaScript to create libraries and applications that make use of AWS services. This AWS SDK is mostly used for browser-based application development which makes it easier for developers to access AWS directly from JavaScript code. The JavaScript API will be available to the user both in the browser and in Node.js apps on the server.

How it Works

The AWS SDK for JavaScript facilitates the use of AWS Services by offering a collection of libraries that are consistent and known to JavaScript developers. It helps with API lifecycle issues like credential management, retries, data marshaling, serialization, and deserialization. Higher-level abstractions are also supported by the AWS SDK for JavaScript for easier development.

Key features

  • First Class TypeScript Support: The Javascript SDK is developed entirely in Typescript and then compiled into JavaScript. This enables you to take advantage of Typescript’s advantages, such as static type-checking and class and module support.
  • Middleware Stack: The AWS SDK for JavaScript provides the middleware stack, which allows you to modify the middleware to tailor the SDK’s functionality. You have the option of adding your custom asynchronous actions to the AWS SDK for JavaScript and/or removing the default ones.
  • Modular Architecture: Reduce the size of your application bundle and enhance its performance by importing only the items that your application requires. The AWS SDK for Javascript features a modular architecture, with a different package issued for each service.


The AWS SDK for PHP allows you to get started quickly with AWS. The AWS SDK is a cutting-edge, open-source PHP toolkit that makes it simple to interface PHP applications with AWS services like  Amazon S3, Amazon Glacier, and Amazon DynamoDB.

AWS SDK for Python

BOTO is one of the AWS for Python programming. It enables Python developers to track software that uses Amazon services such as S3 and EC2.

Boto supports both an object-oriented API and low-level direct service access.

Key Features

  • Resources APIs: Boto3 has two API levels. Client (or “low-level”) APIs give one-to-one mappings to the underlying HTTP API actions. Resource APIs hide explicit network calls and instead give resource objects and collections to access characteristics and conduct actions.
  • Up-to-date Interface: Boto3’s ‘client’ and resource interfaces are powered by JSON models that define AWS APIs. This enables extremely rapid updates while maintaining high consistency across all supported services.
  • Support for Python 2 and 3: Boto3 was built from the ground up to support Python versions 2.7 and 3.4.
  • Waiters: Boto3 includes ‘waiters,’ which automatically monitor AWS resources for pre-defined status updates. For example, you can launch an Amazon EC2 instance and use a waiter to wait for it to reach the ‘running’ state, or you can build a new Amazon DynamoDB table and wait for it to become ready for usage.
  • Service-specific Features: Boto3 includes several service-specific capabilities, such as automated multi-part transfers for Amazon S3 and simpler query conditions for Amazon DynamoDB.

AWS SDK for Ruby

The AWS SDK for Ruby allows users to create apps that utilize AWS infrastructure services. It also contains Amazon S3, Amazon EC2, Amazon DynamoDB, and other services.

AWS SDK for C++

The SDK is a modern, open-source C++ library for easily integrating your C++ application with AWS services such as Amazon S3, Amazon Kinesis, and Amazon DynamoDB.


  • Client-Side Data Encryption for Amazon S3: This simple client-side encryption method contributes to the security of application data stored in Amazon S3. Because encryption and decryption are done on the client side, the private encryption keys are never lost.
  • Amazon S3 Transfer Manager: The Amazon S3 TransferManager improves throughput, performance, and reliability by making heavy use of multi-threaded Amazon S3 multipart uploads via a simple API.
  • Broad Platform Coverage: Built and tested on a range of platforms, including Windows, Linux, Mac, Android, and iOS.
  • CMake Support: Designed to interact with CMake, allowing users to simply compile and link against the SDK without having to know about the SDK’s dependency specifics.
  • Customizable Memory Management: To tailor how memory is allocated and deallocated, you can use your own memory managers.
  • Complete, Up-to-date Coverage of AWS Services:  Supports all public AWS services and is continuously updated to reflect the most recent API changes.

AWS SDK for Go

The SDK makes it simple to interface your Go application with the whole array of AWS services, including Amazon S3, Amazon DynamoDB, Amazon SQS, and others.

If you have any doubts or queries related to AWS, do post them on our AWS Community!

How it Works

The AWS SDK for Go facilitates the use of AWS services by offering a collection of libraries that are consistent and known to Go developers. It includes higher-level abstractions for easier development, such as Amazon S3 Transfer Manager for concurrent multi-part file uploads and Amazon DynamoDB AttributeValue and Expression utilities for easy integration with your application Go types.

Key Features:

  • Familiar Go Experience: The SDK makes use of advanced Go language features. You can use Go modules to represent and control service dependencies required by your application. You can also use Go’s error-wrapping capability.
  • Extensibility: The SDK includes a new middleware stack that allows you to expand or alter the request and response pipeline for each service function. By building numerous middleware together, the SDK employs this same middleware stack to serialize and deserialize wire format messages for each service API operation.
  • Performance: The SDK eliminates costly runtime reflection from wire-formatted message serialization and deserialization. This significantly reduces the SDK’s CPU and memory use, freeing up additional resources for your application.

Tools for AWS

AWS developer tools are basically responsible for version control and application source code securely for easy deployment, building, and testing of the AWS apps.

AWS CodeCommit

Organizations use AWS CodeCommit to host websites in highly secure and scalable git repositories. Code commit basically eliminates the need of operating own source control systems or worry about scaling and infrastructure.

AWS CodePipeline

AWS CodePipline can help in easy building, testing, and deploying the code that is based completely on various process models released.

AWS CodeBuild

AWS CodeBuild is an integration service that helps in compiling source code, running tests, and producing software packages that are ready for deployment.

AWS CodeDeploy

Just like AWS CodeBuild, AWS CodeDeploy is also a fully managed deployment service that helps in automating software deployments to various AWS services like Amazon EC2, AWS Lambda, AWS Fargate, and also in your on-premises servers.


As discussed above AWS SDK or Software development kit is nothing but a solution for making complex coding easier by providing support for various libraries and tools to developers. It also provides support for APIs for better implementations of AWS services and applications.
