ABSTRACT
This chapter looks at there are different types of environments and applications. It provides little data, big data, structured and unstructured data, application performance, availability, capacity, and economics where applications and data get processed. The chapter analyses data infrastructures including servers, storage, and input/output networking hardware as well as software tools. It explains the theme that applications that run on servers have algorithms and data structures that reside in memory and data storage. There are many different types of environments, from small to large web-scale and cloud or managed service providers, along with various types of organization and focus, there are also diverse applications and data needs. For information technology and data infrastructure tradecraft this means expanding from basic tasks to being able to do more advanced things—for example, expanding tradecraft from knowing the different hardware, software, and services resources as well as tools, to what to use when, where, why, and how.
