Fix : Hard Disk Full of MySQL Log Files, MySQL Failing to Start
Server hard disk full is quite common matter, especially on the cloud servers. Usual disk space allocated on common RAM size cloud server instance is 30-40GB. Bigger websites easily eat up 10GB space for the media files. System files including running applications take more than 10GB. And for WordPress, full hard disk will result showing up the infamous "Error Establishing a Database Connection" … [Read more...]
How Are Serverless Computing Platforms Different From PaaS?
How Are Serverless Computing Platforms Different From PaaS? Both backend architectures keep the backend management to zero is one big resemblance. With PaaS, we paying for the whole and but in Serverless Computing, we pay only function execution. Origin of Serverless is plain HTML webpages.
