What should I compare in cloud free tiers?
Compare the entry plan, the billing cycle and the certifications, since free tiers hand out very different amounts. Costimizer lists Growth (free, up to 5 users) at $0 on monthly billing, with SOC 2, ISO 27001 and GDPR and a 14-day Premium free trial, no credit card required. e-Science Central / EGI Federated Cloud starts with 4 vCPU cores, 8 GB RAM, 100 GB block storage and ISO 9001:2015, ISO/IEC 20000 1:2018 and ISO/IEC 27001:2017. See both in Cloud free tiers.
