Potential causes responsible for making an AWS unreachable
AWS is an extensive and robust infrastructure that provides a cloud computing platform. An Amazon EC2 instance is a virtual server in Amazon’s Elastic Compute Cloud (EC2). It runs the applications using the Amazon Web Services (AWS) infrastructure. It facilitates the business subscribers to run application programs in the computing rostrum. One can get the opportunity of utilizing unlimited virtual machines. AWS offers many instances with different configurations to suit the user’s needs. The AWS instance sometimes becomes inaccessible. Troubleshooting the instance when it becomes unreachable without knowing the root causes is critical. An AWS instance can be unresponsive due to issues in network configuration, or when a process consumes large amounts of CPU.

I have designed the fishbone template to get a neat look and feel of my cause analysis. This fishbone is a perfect example of a root cause analysis template. It has most of the main factors that make an AWS instance unreachable.
