Use GMail with your own domain for free thanks to Amazon SES & Lambda
One of the main needs of a small business or startup is to have a reliable mail system with its own domain that helps differentiate on the Internet. Although there are lots of hosting plans offering free email accounts and even you could set up your own mail server, you are probably already used to mail services like GMail and would like to continue using it to also manage mail from your own domain without having to come to paid solutions such as G Suite (formerly Google Apps), which though inexpensive for the services you get in return, they represent an additional cost that your incipient project might not afford.
When we completely fill up an ext4 filesystem mounted on a partition hosted in an EBS volume of Amazon Web Services and we can not do anything to free space because we do not want to lose any of the stored data, the only solution is to grow up the volume and extend the associated partition up to 100% of its capacity to obtain free space again.
