AWS System Administration  (English, Paperback, Sachin Srivastava)

Those who came from a pure development background (without sysadmin experience) would often build an infrastructure that left out many of the things sysadmins would take for granted, such as monitoring and logging. The lack of monitoring and logging would then make it difficult to track down issues, leading to more downtime than was necessary. At the other end of the spectrum were those with a lot of sysadmin experience, but less or no development experience. This group was more likely to treat AWS as nothing more than a virtual machine hosting provider, simply using EC2 to run a fleet of static instances without taking advantage of any high-availability features such as Auto Scaling and Elastic Load Balancers. This is akin to buying a Ferrari and then using it only to buy groceries once per week: fun, but not cost-effective.
