# Benefits of AWS CloudHSM Client SDK 5
<a name="client-sdk-5-benefits"></a>

Compared to AWS CloudHSM Client SDK 3, Client SDK 5 is easier to manage, offers superior configurability, and increased reliability. Client SDK 5 also provides some additional key advantages to Client SDK 3. 

**Designed for serverless architecture**  
Client SDK 5 does not require a client daemon, so you no longer need to manage a background service. This helps users in a few important ways:   
+ Simplifies the application startup process. All you need to do to get started with CloudHSM is configure the SDK before running your application.
+ You don't need a constantly running process, which makes integration with serverless components like Lambda and Elastic Container Service (ECS) easier.

**Better third party integrations and easier portability**  
Client SDK 5 follows the JCE specification closely and provides easier portability between different JCE providers and better third party integrations

**Improved user experience and configurability**  
Client SDK 5 improves log message readability and provides clearer exceptions and error-handling mechanisms, all of which makes self-service triaging much easier for users. SDK 5 also offers a variety of configurations, which are listed in the [Configure Tool page](https://docs.aws.amazon.com/cloudhsm/latest/userguide/configure-sdk-5.html). 

**Broader platform support**  
Client SDK 5 offers more support for modern operating platforms. This includes support for ARM technologies and greater support for [JCE](https://docs.aws.amazon.com/cloudhsm/latest/userguide/java-library_5.html), [PKCS\$111](https://docs.aws.amazon.com/cloudhsm/latest/userguide/pkcs11-library.html), and [OpenSSL](https://docs.aws.amazon.com/cloudhsm/latest/userguide/openssl-library.html). For more information, refer to [Supported platforms](client-supported-platforms.md). 

**IPv6 connection support**  
Client SDK 5.14\$1 supports connections to dual-stack HSMs using IPv6. 

**Additional features and mechanisms**  
Client SDK 5 includes additional features and mechanisms that are not available in Client SDK 3, and Client SDK 5 will continue to add more mechanisms in the future.
