Elastic Load Balancing
Problems with multiple servers
TYPO3 Flow sessions are stored in local file cache
Logging goes to local filesystem
Uploaded resources are stored on local filesystem
TYPO3 Flow sessions are stored in local file cache
Solution:Change TYPO3 Flow’s session backend to a
database or redis backend (e.g. ElastiCache)
Logging goes to local filesystem
Solution: Ship log files to a central logging server
CloudWatch
Uploaded resources are stored on local filesystem
Solution:Upload resources to a shared file service (e.g. Amazon S3)
Amazon S3
“Amazon S3 provides developers and IT teams with secure, durable, highly-scalable object storage.”
Easy to use
Cheap
Highly-scalable
Durable

And more …
Start cost
My experience so far:99% predictable, 1% unknown
2 x t2.micro (with SSD)…………… ~ $30 1 x Load Balancer ………………………… ~ $20 1 x MySQL with failover…………… ~ $30 1 x MySQL Read replica …………… ~ $15 S3, Route 53, SES, SNS etc…… ~ $ 5 ——
Total ………………………………………………………… ~ $100 / month
AWS Pricing is very complex and hard to predict.

Some of the reasons why I love AWS:• Fairly easy to get started (with a very advanced setup) • File/push/email/queue/cache/… services are super useful and easy to use • The auto-healing / auto-scaling features gives me peace of mind • Feels confident that we can scale easily using horizontal scaling
