Introduction:

IMS Training | NFV Training | IMS Network Functions Virtualization (NFV) Training in the Nutshell

IMS Training | NFV Training | IMS Network Functions Virtualization (NFV) Training covers all aspects of IT virtualization technologies, virtual machines running different software and processes, applied to consolidate network equipment types with standard high volume servers, switches and storage components. The objective of IMS NFV is to taking the physical networking devices commonly used today in IMS including switches, storage, routers, load balancers, firewalls, IDS, cloud computing infrastructure, etc. and virtualizes them in much the same manner as servers.

NFV decouples the network functions, such as network address translation (NAT), firewalling, intrusion detection, domain name service (DNS), and caching, to name a few, from proprietary hardware appliances so they can run in software. IMS NFV training shows attendees how to translate the classic network appliances to software modules running on high volume servers with high volume storage, interconnected by generic high volume switches and automatically orchestrated and remotely installed. IMS NVF training also covers the integration with Software Defined Networking (SDN) technologies, OpenStack and other frameworks.

The objective of IMS NFV NFV is to taking the physical networking devices commonly used today (switches, routers, load balancers, firewalls, antivirus, etc.) and virtualizes them in much the same manner as servers. IMS NFV will be used to scale out across IMS devices less expensively (scaling by simply adding compute power) and to automatically deploy devices as needed.

Customize It:

● If you are familiar with some aspects of this course, we can omit or shorten their discussion.
● We can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those included in this outline).
● If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the course in manner understandable to lay audiences.
