4 AWS Tools to Modernize your Applications for Enhanced ROI

Imagine modernizing your application and integrating AI for an immersive experience. Spotify is trying to create a DJ feature to help customers curate playlists with AI-powered commentary. Developing features and modernizing the application requires cloud-native capabilities. AWS application modernization tools come in handy.

AWS provides many different types of tools and services that you can use to modernize your applications. The best part about these tools is their flexibility. You can customize AWS tools and services to your project requirements and optimize application modernizations for better ROI.

So, here is a comprehensive list of the best AWS tools you can use for application modernization projects.

Top AWS application modernization tools

AWS offers more than 200 different cloud services that you can use for application modernization. However, you need to choose the one suitable for your project, so here is a list of top options.

1. AWS Lambda

AWS Lambda is a serverless computing platform with advanced computing services that enables event-driven computing. Without having to provision servers or manage resources, it allows you to run code.

Changes in data, user activity, and any other system occurrence are all events that cause lambda functions to occur. The flexibility of AWS Lambda allows tech teams to deploy tasks on demand, eliminating the need for manual server management.


  • It is a simple, cost-effective platform that makes it easy to deploy code with minimal upfront work.
  • The event-driven architecture of AWS Lambda helps you handle real-time responses better.
  • You can deploy your code without having any server provisioning or management required - perfect if you want to quickly outsource specific tasks while keeping your production systems running smoothly!
  • AWS Lambda enables you to quickly prototype and deploy code without waiting for a full-fledged DevOps pipeline to be put in place.

*Cons *

  • AWS Lambda lacks batch processing capabilities for specific use cases
  • It has scalability issues significantly while scaling up in frastructure to process BigData

2. Amazon ECS

Amazon ECS is a fully managed containerization service. It allows you to deploy, scale, and manage containerized applications. Amazon ECS is a fantastic option for updating applications and adopting the microservice architecture. The best part about Amazon ECS is the ability to set up autoscaling which you can do using AWS-CLI, AWS-Console, and AWS SDKs.

*Pros *

  • Manages all the resources for your containerized applications
  • You can use Amazon ECS to deploy your containers into AWS environments
  • Ensures that your applications are secure by provisioning them with two layers of security


It is a heavyweight service and requires some setup time.


Kubernetes offers orchestrated container implementation. This is where AWS EKS helps you manage Kubernetes clusters and run them in the AWS environment. It also allows companies to deploy Kubernetes clusters without the need for provisioning.


  • Highly secure for your application with enhanced backup and recovery options
  • A production-ready platform that makes deployment easy
  • Seamless integration into AWS services and other tools


  • Compared to other services, EKS can be expensive
  • Manual updating of EKS makes it challenging
  • Installation and configuration of integrating other services with EKS are complex.

4. AWS Fargate

If you want to run containers without managing servers or clusters of EC2 instances, AWS Fargate is the best choice. It is a serverless computing engine for running workloads in the AWS cloud. You can use it with Amazon ECS and reduce container provisioning, configuration, and management.


  • As a CaaS (containers as a service) solution, managing, scaling, and deploying containers is easy with AWS Fargate.
  • Better integration with other services like EKS and ECS
  • Using AWS Fargate spot can help reduce the costs


  • Limited control over the networking layer
  • Less transparency on container management


Undoubtedly, AWS application modernization requires effective implementation and management of workloads. AWS cloud services provide several advantages for businesses looking to modernize their apps, reducing workload management.

Services like AWS Fargate and EKS container management become efficient. However, understanding these services' pros and cons is key to deciding which suits your project better.
