Migrating IT to the cloud

Sooner or later, it becomes obvious that running a large number of the IT portfolio—perhaps even the majority of it—in the cloud makes sense from a variety of perspectives. In most cases, running in the cloud provides substantial cost savings; reduces or eliminates the need for an enterprise to maintain its own datacenters; reduces or eliminates the need to manage hardware and software updates; and enables the sort of innovation we discussed in Chapter 1. The cloud is very compelling; yet the migration phase typically involves many more applications and many more people, and potentially impacts more of IT’s customers than any other—by far

Building the catalog

How then do you prioritize the migration of applications to the cloud? To understand what applications should be moved, when, and how, it’s important to create a wellattributed catalog of applications managed by IT. Then, the relative importance of each attribute (say, business criticality or amount of system integration) can be weighted and the prioritized list can be built

NoSQL (nonrelational) storage

The NoSQL arena has many options, ranging from simple object storage to complex document and graph-based data stores. 

BASIC DATA TYPES

There are several different basic data types and it’s important to know what you can do with each of them so you can collect your data in the most appropriate form for your needs. People describe data types in many ways, but we’ll primarily be using the levels of measurement known as nominal, ordinal, interval, and ratio.
