Infrastructure management (IM) and Development | JST Business Means Everything you need for your Business
For an organization's information technology, infrastructure management (IM) is the management of essential operation components, such as policies, processes, equipment, data, human resources, and external contacts, for overall effectiveness.
Infrastructure management is sometimes divided into categories of systems management, network management, and storage management. Infrastructure management products are available from a number of vendors including Hewlett-Packard, IBM, and Microsoft.
Among other purposes, infrastructure management seeks to:
Reduce duplication of effort
Ensure adherence to standards
Enhance the flow of information throughout an information system
Promote adaptability necessary for a changeable environment
Ensure interoperability among organizational and external entities
Maintain effective
change management policies and practices
Although all business activities depend upon the infrastructure, planning and projects to ensure its effective management are typically undervalued to the detriment of the organization.
Network Management
In information technology, networking is the construction, design, and use of a network, including the physical (cabling, hub, bridge, switch, router, and so forth), the selection and use of telecommunication protocol and computer software for using and managing the network, and the establishment of operation policies and procedures related to the network.
IT Systems Management
Systems management is the administration of the information technology systems in an enterprise data center. An effective systems management plan facilitates the delivery of IT as a service (ITaaS) and allows the organization's employees to respond to changing business requirements in an agile manner. In a hybrid IT environment, this involves overseeing the design and day-to-day operations of the data center, as well as the integration of third-party cloud services.
Data Storage
In a computer, data storage is the place where data is held in an electromagnetic or optical form for access by a computer processor.
Storage is frequently used to describe the devices and data connected to the computer through input/output (I/O) operations -- that is, hard disk and tape systems and other forms of storage that don't include computer memory and other in-computer storage. For the enterprise, the options for this kind of storage are of a much greater variety and expense than those related to memory.
Storage hierarchy
Enterprise data storage is often classified as primary and secondary storage, depending on how the data is used and what type of media it is placed on.
Primary storage holds data in memory (sometimes called random access memory or RAM) and other built-in devices, such as the processor's L1 cache. Secondary storage commonly includes data on hard disks, tapes and other devices requiring I/O operations. Secondary storage media is often used in cloud storage.
Primary storage is much faster to access than secondary storage because of the proximity of the storage to the processor and the nature of the storage devices. On the other hand, secondary storage can hold much more data than primary storage.
Antiquated terms for primary and secondary storage are main storage and auxiliary storage, respectively. To add to the confusion, there is an additional meaning for primary storage that distinguishes actively used storage from backup storage.
Types of storage
There are many types of data storage, with various levels of capacity and speed. These include magnetic tape; magnetic disks; optical discs, such as CDs, DVDs and Blu-ray disks; flash memory; main memory (dynamic RAM); and cache memory.
