In EC2 you have six different volume types, I will provide an broad overview but for more information regarding specifications the AWS documentation is excellent. gp2/gp3 is SSD storage which balances price and performance for multiple types of workloads. io1/io2 is high throughput, high cost, SSD storage used for critical or high performance applications. st1…

EBS in AWS is great, it’s a quick and easy way to get storage, but what if you want even better performance? Well that’s where instance stores come in. It is like connecting your EC2 instance directly to a physical drive on a server, you get much higher IOPS then you would on an EBS…

AMI, or Amazon Machine Image, is a powerful tool used in AWS that allows you to build a custom prepackaged image or use a prepackaged image provided by a 3rd party vendor or amazon that includes configuration, software, monitoring etc. An advantage of this is your system will have a faster boot time as this…
