Source: A Detailed Explanation of Why Developers Are Migrating to Arm Platforms
Developers understand that building applications that can scale efficiently while controlling costs is crucial. Cloud technology is evolving rapidly, and the underlying technologies are also continuously developing. In recent years, more and more companies have realized that migrating their applications from x86 architecture to Arm architecture brings numerous advantages. The Arm architecture not only significantly enhances performance but also effectively reduces the Total Cost of Ownership (TCO), making it the preferred architecture for companies looking to adapt their workloads to future challenges.

The Arm Architecture Offers Exceptional Performance and Efficiency

Processors based on the Arm architecture (such as AWS Graviton, Google Axion, and Microsoft Azure’s Ampere-based products) are designed to deliver outstanding performance at a lower cost. Migrating to Arm-based cloud instances can save up to 60% in energy consumption while providing a 50% performance boost, creating new opportunities for developers looking to optimize their workloads. Arm also offers higher density cores, enabling greater scalability and the ability to handle more tasks simultaneously.

Moreover, flexibility is a core consideration in Arm architecture design, ensuring that developers’ products can withstand future tests. When developers migrate their workloads to the Arm platform, they can be compatible across multiple cloud service providers, allowing for flexible application scaling on various Arm-based cloud platforms, including AWS, Google Cloud, and Microsoft Azure.

One Migration to Fully Enjoy the Complete Arm Cloud Ecosystem and Workflows
As major cloud service providers increasingly adopt Arm-based solutions, software compatibility and performance are continuously improving, allowing developers to leverage the advantages of the Arm platform more easily. Specifically for Artificial Intelligence (AI) workloads, Arm focuses on dedicated processing and heterogeneous computing, enabling machine learning (ML) algorithms to execute efficiently. Thanks to the combination of high energy efficiency, scalability, and AI acceleration capabilities, the Arm ecosystem is well-suited for enterprises looking to optimize their cloud infrastructure and AI applications.

Successful Customer Cases Based on the Arm Platform

Honeycomb and FusionAuth both demonstrate that migrating to Arm-based infrastructure is both simple and beneficial.

1. Honeycomb Reduced Infrastructure Costs by 50%

Honeycomb, a front-runner in the observability field, migrated from traditional architecture to the Arm-based AWS Graviton processors to meet its massive data processing needs. The migration was highly effective and immediate. Honeycomb not only reduced the number of instances but also cut infrastructure costs by 50%, all while maintaining high performance. After this migration, Honeycomb can focus on its core strengths—deeply analyzing system behavior—without worrying about rising infrastructure costs.

2. FusionAuth Increased Login Rates by Up to 49%

The migration to Arm was not just an attempt but a breakthrough. After load testing on Arm-based AWS Graviton instances, FusionAuth found that login rates increased by 26% to 49% compared to traditional systems. Not only was the migration process very smooth, but the company also achieved a cost saving of 8% to 10%. Currently, most of FusionAuth’s cloud infrastructure runs on Arm-based instances, supporting a wide range of use cases from IoT to high-performance cloud platforms.

The Migration Journey Is Simpler Than Expected

The process of migrating from traditional architecture to Arm architecture is very smooth, requiring no large-scale rewriting of code. Companies like Honeycomb and FusionAuth successfully completed the migration with the powerful developer tool ecosystem provided by Arm, along with support for code adaptation, testing, debugging, and performance optimization. Whether developers are using Java, Golang, or other popular languages, Arm is compatible with their existing tech stack. The flexibility of the Arm architecture ensures that developers’ applications continue to perform excellently with lower resource demands, achieving a higher cost-performance ratio.
Developers should first assess their existing software stack, including operating systems, programming languages, development tools, and dependencies. Then, they need to set up a development environment that supports Arm architecture, which can be achieved through emulation, remote hardware, or physical Arm architecture hardware. During migration, applications written in compiled languages like C/C++, Go, and Rust often need to be recompiled, while interpreted languages like Python, Java, and Node.js require minimal modifications.
Developers should also ensure that all necessary technical libraries and dependencies can run on the Arm platform. Testing and validation are critical steps that help identify and resolve any compatibility issues. Finally, developers can deploy workloads compatible with the Arm platform to cloud providers like AWS, Google Cloud, and Microsoft Azure, all of which offer strong support for Arm-based instances.
Whether developers are creating battery-powered devices, embedded systems, or IoT applications, migrating to the Arm platform is a strategically significant decision that not only saves costs but also provides excellent performance and sustainability. Developers around the world are choosing the Arm platform to build more reliable, scalable, and energy-efficient applications!
