This week we moved a Craft CMS website to a LightSail cloud server managed by us.
Previously, this site was hosted at one of the 'recommended' and in Craft CMS specialized service providers. The performance of this provider degraded seriously over the past year, rendering the work of CMS editors almost impossible.
After the migration, performance problems vanished. On the contrary, the page rendering speed was twice as fast.
Our load tests indicated that even under high pressure, the new server was quite performant, while the previous setup became very slow with response times over 10 seconds.
Besides the speed improvement for the craft website, the monthly costs are expected to decline seriously - in this case to about 20% of the previous monthly costs.
