Many organizations are struggling to drive more value, utility, and efficiency from data centers. The pursuit of a more efficient and powerful data center now revolves around virtualization. Legacy data centers have given way to virtualized network architectures or in other words, virtualized data centers.
Old data centers can be retrofitted and expanded into highly-efficient network architectures. Whereas new data centers would be built utilizing virtualization as a core component of the design. Virtualized data centers can run more agile applications and serve as a strong foundation for cloud-based computing.
Here we would be discussing to Cisco products as well as provide an introductory level knowledge of how Cisco-powered data centers work, how they would be designed, as well as what devices they would be utilizing. But before that, if you wish to have Cisco Certification in a single attempt, you should gain the study dumps provided by the SPOTO Club.
The Concept of Technology Virtualization
VMWare pioneered virtualization of network hardware like servers, routers, as well as switches. The company would be defining the idea of virtualization as the process of creating a software-based representation of something rather than a physical one. This would apply to applications, servers, storage, as well as networks. This technology revolutionized the industry as well as made VMWare a leader in virtualization. Other players in the market would be recognized as the immense potential and started working on their solutions. According to a study by ACG Research, Cisco would be the number one telecommunications vendor in the world. The company followed suit and begin focusing on virtualization solutions.
Legacy Data Centers and Data Center Virtualization
A decade ago, data centers were simply a collection of servers connected through a complicated pathway of power lines and network cables. This set up generated a lot of heat and powerful Computer Room Air Conditioners (CRAC’s) cooled the rooms. Any thermal failure would cause downtime as servers crashed. Not an ideal set up but was tolerated because there was no viable alternative.
The Power of Cisco Data Center Virtualization Technology
Cisco would be occupying a distinct place among network hardware vendors because of its systems-level approach that would be aiming for total service integration throughout the entire infrastructure. A large number of their Layer 3 switches would be having the ability to support network virtualization.
Cisco Network Virtualization solutions would be designed to help organizations easily implement network virtualization. As businesses realize the benefits of virtualization, the industry has seen a boom in SDN otherwise known as Software Defined Networking and NFV which means Network Functions Virtualization solutions.
How Does Cisco Network Virtualization Work?
Virtualization could be combined with multiple physical networks for creating a single virtual network. It is also possible to logically partition one large network into multiple logical networks. These partitions can serve specific distinct business needs. Cisco devices and network virtualization solutions would be focusing on three major areas of network virtualization.
- Access Control — Allows enterprises to set up secure customized access rules to protect internal LANs from threats.
- Path Isolation — Securely maps validated devices and users to the right resource
- Services Edge — Enforces a central access policy that lets users access, share, and deploy services.
