What is the Computer Networking ?
Computer networking is the subject which explains how computers connect with each other for sharing resource and information and what technologies and devices they use for the connectivity.
Benefits of Networking
Computer networking provides the following benefits.
• It allows us to share data and resources.
• It helps us in reducing the required number of devices.
• It provides us a platform to communicate with other users in network.
• It allows multiple users to work on a single project.
• It allows us to store data in a centralize location.
• It allows us to implement the security policies.
• It allows us to track and monitor the use of resources.
What is Server Virtualisation ?
In a nutshell
Server Virtualisation software is an abstraction layer between operating systems, applications and actual physical platforms. The operating system sees a consistent, uniform set of hardware no matter what components are in the physical machine.
When encapsulated in virtual machines, full systems (applications, OS, BIOS and virtual hardware) are easily transportable between different physical machines, because the Virtualisation layer isolates them from the change of platform.
Server Virtualisation is a form of partitioning because multiple virtual machines can be run simultaneously on the same physical platform, unaware and hence essentially unaffected by the presence of other virtual machines.
Development and Test optimization
CIO’s are under constant pressure to deliver high-quality enterprise applications more quickly at a lower cost. It has been never easy to deliver quality software on time and on the budget. The task is further complicated by modern multi-tier architectures and multiple versions of operating systems, browsers, and firewalls. Hence, using a Virtualisation platform for development and testing results in immediate improvement in time to market, costs, and quality.
Virtualisation and Server Consolidation
Virtualisation enables enterprises to:
• Consolidate servers and desktops used in production and development environments
• Reduce costs by lowering the number of phyiscal servers while increasing hardware utilisation
• Support complex mult-tier applications on a single physical platform.
Improved Storage Access
The SAN becomes a pooled resource that hosts operating systems (encapsulated) and data providing thus, greatly improve realiability and avaliability of services. Therefore, the costs are reduced because servers effectively share fewer ports and cards to access pooled resources.
Business Continuity & DR
Each year hundreds of data centres worldwide will experience significant unplanned service interruptions. Using virtual infrastructure, IT managers can improve all aspects of business continuity & DR by realising:
• Faster, more flexible, and more reliable disaster recovery at a lower cost achieved through the removal of dependencies of operating systems on specific server hardware
• Copy production environments into virtual machines for testing and share complete environments among different teams
• Simplified and repeatable processes for implementing business continuity solutions enabled by hardware independence.
How can Application Delivery Controllers benefit my business
Lower total cost of ownership
ADC delivers up to 80 percent savings in training, power, space and overall costs. Therefore, it delivers more applications to more users while reducing server costs by up to 60 percent. ADC offloads intensive and repetitive tasks off servers,thus holds dynamic content generated by servers in in-memory cache and shields servers from unwanted traffic. This reduces the number of servers and network devices, and allows you to deploy new Web 2.0 applications without extensive infrastructure changes.
Improved operational efficiency
As enterprises grow, IT needs to rapidly increase bandwidth and computing capacity – often in the form of increased Internet capacity, IT services support and server resources. The resulting expenditures are costly in terms of capital and people needed to operate and manage delivery infrastructures.
Intelligent Load Balancing and Content Switching
ADC’s provides comprehensive layer 4-7 traffic management. Deployed in front of application servers, they deliver fine-grained load balancing of client requests. Thus, it ensures optimal distribution of traffic. Intelligent traffic management and extensive server health checks provide greater business continuity and thus, eliminate the application server as a single point of failure. It is easy to define traffic management policies based on layer 4 traffic information (protocol and port number), as well as application-layer information such as URLs, application data type or cookie.
Guard against Denial of Service Attacks
Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are assaults on a network that flood it with so many additional requests that regular traffic is either slowed or completely interrupted ADC solutions provide intelligent Layer 4 / Layer 7 DoS and surge protection to ensure your web services are robust and available
