Why and How to Choose Arm64 for Your Cloud Applications

Learn how to evaluate and implement Arm64 architecture for cloud applications in this comprehensive conference talk from DevConf.US 2025. Explore the evolution of CPU architectures from x86 dominance to the emerging Arm64 ecosystem, driven by factors like Raspberry Pi adoption, Apple's architectural shift, and cost-effective cloud server options that are typically 20-30% cheaper per core hour than equivalent x86 instances. Discover the practical benefits of running cloud applications on Ampere and other Arm64 instances, including performance improvements and cost reductions demonstrated through real-world case studies. Master the decision-making process for workload migration by understanding which application components to move first and how to implement architecture-specific placement strategies. Address common concerns about dependency support, software rebuilding and requalification requirements for Arm64 servers. Gain hands-on knowledge of containerizing software for multiple architectures using Podman and related tools, while learning to update CI processes for multi-architecture container builds. Understand workload placement strategies on Kubernetes and discover how to use ArgoCD Rollouts as a safety net for incremental application migration to Arm64. Examine the impact on supporting cloud application functions including log management, observability, and service mesh components to ensure comprehensive architectural transition planning.
