Whenever there is a need to back up the data, AWS API and AWS CLI play a vital role in automating the process through scripts.

How will you ensure that the database hosted on your EBS volume is backed up?Īutomated backup are the key processes here as they work in the background without requiring any manual intervention. Imagine that you have an AWS application that requires 24x7 availability and can be down only for a maximum of 15 minutes.Also, the performance can be improved by using Linux software raid and striping across four volumes. One can backup EBS volumes through a graphical user interface like elasticfox or use the snapshot facility through an API call. Virtual AWS instances do not behave this way. SLA provides an average disk I/O rate which can at times frustrate performance experts who yearn for reliable and consistent disk throughput on a server. it can go above the SLA performance level and after that drop below it. Performance of an elastic block storage varies i.e. What type of performance can you expect from Elastic Block Storage? How do you back it up and enhance the performance ?.Get FREE Access to Data Analytics Example Codes for Data Cleaning, Data Munging, and Data Visualization
