1. Internet Architecture

2. Data Center Technology
 Data Center :
 A data center is a building, a dedicated space within a
building, or a group of buildings used to house computer
systems and associated components, such as
telecommunications and storage systems.
 Key components of a data center design include routers,
switches, firewalls, storage systems, servers, and
application-delivery controllers.

3. Data Center Technology
 Data Center Supports :
1. Email and file sharing
2. Productivity applications
3. Customer relationship management (CRM)
4. Enterprise resource planning (ERP) and
databases
5. Big data, artificial intelligence, and machine
learning

4. Data Center Technology
 The purpose of data center is :
 Running the applications that handle the core
business and operational data of the organization.
 House the equipment to secure, store and exchange
data.

5. Data Center Technology
 Five core elements of data center
 User Application
 Database
 Network
 Storage Array
 OS and server

6. Data Center Technology
 Colocation Data Center
 China Unicom’s Global Center data center in
Hong Kong

7. Data Center Technology
 Colocation Data Center
 Also known as simply colo, a colocation data center is a large
facility that rents out rack space to businesses for their
servers and other network devices.
 It is one of the most popular services used by organizations
that may not have sufficient resources to maintain their own
data center but still want to enjoy all the benefits.
 A colocation facility provides space, power, cooling, and
physical security for the server.

8. Data Center Technology
 Managed Data Center
Example: Fully-managed IBM Cloud Services

9. Data Center Technology
 Managed Data Center
 This type of data center model is deployed,
managed, and monitored by a 3rd-party service
provider.
 It offers all necessary features through a
managed service platform.
 The service provider performs the maintenance
of all network components and services,
upgrades operating systems and other system-
level programs, and restores data/services in

10. Data Center Technology
Enterprise Data Center


Example: Facebook’s Forest City Data Center in North
Carolina

11. Data Center Technology
Enterprise Data Center
 The enterprise data center is a private facility designed for the sole
purpose of supporting a single company.
 It can be located on-premises or off-premises at a site, as per the
customers’ convenience.
 If you are running a website from Canada, and your target audience is
students in the United States, you will prefer to build a data center in
the US to reduce page-load time.

12. Data Center Technology
Cloud Data Center

Example: Cloud services offered by Google, IBM,
Amazon (AWS), Microsoft (Azure), etc.

13. Data Center Technology
Cloud Data Center
 the actual hardware is run and managed by the
cloud company, often with the help of a 3rd party
managed services provider.
 data is fragmented and duplicated.
 backup of your backup


14. Virtualization Technology
Virtualization:
 Allows to share a single physical instance of an application
or resource among multiple organizations or customers.
 Makes it possible to run multiple OS and applications on
same server at the same time.
 It is a process of creating a logical version of server operating
system, storage device or network device.
 Virtual Machine Monitor

17. Virtualization Technology
OS Virtualization:
 When the virtual machine software or virtual machine
manager is installed on the Host OS .
 Mainly used for testing the applications on different
platforms or OS.
 Server Virtualization:
 When the virtual machine software or virtual machine
manager is installed on the server system.
 A single server can be divided into multiple servers on the
demand basis and for balancing the load.

18. Virtualization Technology
Hardware Virtualization:
 When the virtual machine software or virtual machine
manager is installed on the hardware system .
 Mainly done for the server platforms.
 Server Virtualization:
 It is a process of grouping the physical storage from multiple
network storage devices so theat it looks like a single storage
device.
 Mainly done for back up and recovery purpose.
