In terms of time, the reduction in manual work is significant. A whole day of 12 hours is now reduced to less than 30 minutes, depending on what we are doing. Once you have the code, you can always copy and reuse it somewhere as long as you know what you are doing. In terms of security configurations, we monitor all servers in various availability zones. We look at how we can automate this in our infrastructure such that once we detect something is coming up, we can patch all servers at once. This reduces our concentration on repetitive tasks and allows us to focus more on delivering availability to the customers and company resources.
This has brought employee happiness, with developers saying that the work environment with available servers and infrastructures has improved by approximately 90 percent. We used to work with people on the sites who continually monitored servers and deployed servers. Now we deploy servers and then we wait while we automate using Chef and monitor those which are about to fail. We monitor them and create scripts to change how they operate, take some down, bring some up, and do load balancing when we need to start a load balancer, without physically having somebody do that every single day unless it is necessary.
This has given the organization an ability to focus more on new challenges that come in, not doing the mundane tasks of every day of infrastructure development. We save more on money in terms of time and also in terms of security applications, deployment, and bringing our infrastructure up. The reduction in employees needed means we don't have to recruit more. We look at those who are there, allowing them to save time to focus on themselves, improve, and learn more about how to make their infrastructure better every day.
