In this post i am gonna tell you, about how IT infrastructure is organized in Multinational software companies.This post can also be used as a reference for non software companies also.With technology infrastructure i mean how various people are connected with each other , how mails and other message applications are organized .We are not going into details of development infrastructure.We are only going into details of the underlying support infrastructure.
So what are the requirements of IT infrastructure ?
First of all IT infrastructure should connect each and every person of the company irrespective of office location.
IT infrastructure should also connect each and every department of the company with each employee of the company irrespective of office location.
The communication should be fast .The communication should not be delayed.
The communication channel should be broad . If one person wants to share a file with other person , proper channel must be there .
It should be secure .
Various infrastructure channels and tools must be accessed at a click of a mouse.
Various software and hardware tools which are used to implement this IT infrastructure.
Lets start with core of IT infrastructure .The core consists of intranet.
Suppose my company is located in different locations across the world.Each of this location can contain one or more offices. The systems in these offices are connected to each other . The offices in one location are connected to each other
likewise all offices in all other locations are connected .These locations which may spread across the world are also interconnected.This forms the intranet of a company.
Basic intranet is comprised of hardware and software .Hardware includes cable , servers , routers and various other equipments . Software comprises of servers like unix or windows server and some other tools which are basically hidden from the end employee.
But this is the core and nothing to do with most of employees except IT department which handles and maintain these resources.
Applications for IT infrastructure
Most important application in IT infrastructure is email.Every company maintains it email policy .Each employee of the company is given a company email id like firstname.lastname@example.org.
Now the email technology is privately employed by company.For example a company may choose to microsoft platform to implement their email infrastructure .Example of software are microsoft exchange sever and microsoft outlook.
Besides email company maintains a chat type software known as office communicator . This software can be used to communicate with any employee of the company. Besides chatting this software can be used to share files , share screens ,allowing remote control etc .One such example of this tool is Microsoft lync.
Next for security purposes , a desktop and server monitoring tool is also installed in each and every system.This tool maintains logs of system usage.
Another thing is that each and every employee has an employee id . This id is synchronized with your company email id.
You can use this id to login into your system and other software tools.
Another important hardware which is connected to company intranet is voice over ip phone .Most of the employees are provided with ip phone .
Another software tool is support system .This software is maintained at company intranet .Whenever you need help or resource with any department of company raise a call (known as ticket ) on this application,Your query will be solved in 24 hrs max by the concerned department employee.From hairpin to airplane ticket anything can be availed with this system.
Now suppose you are not in any company office and want to access your mails or in short company intranet.How will you do that ? You can use internet to connect to your company intranet with vpn.
SAP tools are used to maintain employee information like his salary and other information.
Remember intranet is protected by very powerful firewalls and everything is logged .
So this forms the brief view of technology infrastructure of most companies.
