Case Study: amaysim achieves 99.99% uptime, faster releases, and scalable growth with Amazon Web Services

Amaysim - Customer Case Study

amaysim is an Australian SIM‑only mobile provider founded in 2010 that rapidly grew to become the largest MVNO in Australia with over 700,000 customers. The company ran its services on aging on‑premises infrastructure (about 20 servers and 100 VMs across three data centers), which caused scaling problems, a major 10‑hour outage that created an eight‑day backlog, and forced monthly, off‑hours releases because there were no separate test/dev/staging environments.

amaysim migrated to AWS with help from PolarSeven and Bulletproof, adopting EC2, ELB, RDS, S3, SQS, SNS, CloudFormation, CloudWatch and Redshift plus a DevOps and automation‑first approach (including Auto Scaling). The move delivered up to 99.99% availability, cut incident resolution from week‑long events to under an hour, enabled weekly releases and rapid environment provisioning, and supported growth from 500,000 to 700,000+ customers without expanding the six‑person operations team.
