List of the Top 3 Infrastructure-as-a-Service (IaaS) Providers for LocalStack in 2026

Amazon Web Services (AWS) is a global leader in cloud computing, providing the broadest and deepest set of cloud capabilities on the market. From compute and storage to advanced analytics, AI, and agentic automation, AWS enables organizations to build, scale, and transform their businesses. Enterprises rely on AWS for secure, compliant infrastructure while startups leverage it to launch quickly and innovate without heavy upfront costs. The platform’s extensive service catalog includes solutions for machine learning (Amazon SageMaker), serverless computing (AWS Lambda), global content delivery (Amazon CloudFront), and managed databases (Amazon DynamoDB). With the launch of Amazon Q Developer and AWS Transform, AWS is also pioneering the next wave of agentic AI and modernization technologies. Its infrastructure spans 120 availability zones in 38 regions, with expansion plans into Saudi Arabia, Chile, and Europe’s Sovereign Cloud, guaranteeing unmatched global reach. Customers benefit from real-time scalability, security trusted by the world’s largest enterprises, and automation that streamlines complex operations. AWS is also home to the largest global partner network, marketplace, and developer community, making adoption easier and more collaborative. Training, certifications, and digital courses further support workforce upskilling in cloud and AI. Backed by years of operational expertise and constant innovation, AWS continues to redefine how the world builds and runs technology in the cloud era.

Run your code without the complexities of server management and pay only for the actual compute time utilized. AWS Lambda allows you to execute your code effortlessly, eliminating the need for provisioning or handling server upkeep, and it charges you exclusively for the resources you use. With this service, you can deploy code for a variety of applications and backend services while enjoying an entirely hands-off experience. Just upload your code, and AWS Lambda takes care of all the necessary tasks to ensure it operates and scales with excellent availability. You can configure your code to be triggered automatically by various AWS services or to be invoked directly from any web or mobile app. By managing server operations for you, AWS Lambda allows you to concentrate on just writing and uploading your code. Furthermore, it dynamically adjusts to meet your application's requirements, executing your code in response to each individual trigger. Each instance of your code runs concurrently, managing triggers independently while scaling based on the demands of the workload, which guarantees that your applications can adapt seamlessly to increased traffic. This capability empowers developers to focus on innovation without the burden of infrastructure management.

Infrastructure as Code has progressed to facilitate the creation, deployment, and management of cloud infrastructure through the use of popular programming languages and tools. By offering a cohesive workflow across various cloud platforms, it enables users to apply the same language and tools regardless of the hosting environment. This promotes better collaboration between developers and operators, creating a more integrated engineering atmosphere. The process of continuous delivery is made straightforward, allowing for deployments directly from the command line or via integration with preferred CI/CD systems, while also enabling thorough reviews of changes before they go live. Enhanced visibility across environments simplifies the management of complexity, leading to more effective oversight. Security and audit trails are maintained by tracking modifications, including who made them, when they occurred, and the rationale behind each change, all while ensuring that deployment policies are enforced through the designated identity provider. Secrets management becomes more efficient with built-in encrypted configurations designed to safeguard sensitive information. You can define your infrastructure using a variety of well-known programming languages such as JavaScript, TypeScript, Python, Go, or any .NET language like C#, F#, and VB. This flexibility allows you to leverage your favorite development tools, IDEs, and testing frameworks to boost productivity. Additionally, the ability to codify and disseminate best practices and policies within your team promotes a culture of reuse and efficiency. Ultimately, this methodology not only enhances operational effectiveness but also empowers teams to perpetually innovate and adapt to new challenges. By embracing these practices, organizations can achieve a competitive advantage in a rapidly changing technological landscape.
