You don't have to break what works to move forward
Application Modernization includes a lot more than just your applications. To handle that modern application, you need modern runtimes, build processes, code pipelines, and infrastructure. But modernizing apps shouldn’t slow down your business operations. Upsun helps teams safely migrate from legacy systems without forcing major rewrites or complex infrastructure work.

Meet security and compliance requirements
Meet PCI DSS, ISO 27001, and SOC 2 Type II requirements out of the box. Automated backups, WAF, anti-DDoS, and 24/7 expert support included.
Real-time observability and control
Built-in monitoring and alerts show exactly how your applications perform. Spot issues instantly and fix problems fast with built-in profiling.
Scale on demand
Automatically scale resources as usage grows. Set your thresholds once, and Upsun adds or removes instances based on traffic; no manual intervention during spikes.
Deploy without disruption
Deploy updates, migrations, and new services without disruption with built-in backups, environment isolation, and zero-downtime deployment patterns to ensure your service stays active.
Your tools, your way to modernize
Multiple cloud options
Run applications on AWS, Google Cloud, Azure, IBM, or OVHcloud, without needing custom application architecture. Choose regions based on performance, compliance, or sustainability needs.
Built-in security
DDoS protection, web application firewalls, automated backups, and role-based access controls. Upsun manages these protections centrally to help keep applications secure without setup or operational overhead.
