Reaping The Benefits Of WAN Optimization Controllers

Though ensuring acceptable and standard application delivery has always been a crucial aspect, historically it was never a top priority for IT enterprises. It underwent a change many years back when the IT organizations started to focus in a dedicated manner on application delivery on a huge part of responding to the performance challenges related to supporting applications that were in turn delay sensitive and supporting huge file transfers between branch offices and headquarters. A major medium through which IT enterprises were responding to these performance challenges was by implementing WAN optimization controllers.

 

In most cases, WAN optimization controllers were deployed as a “stand-alone” hardware-based device. Owing to the mass adoption of Virtualization, IT enterprises today are witnessing a new kind of application delivery challenges. For instance, successful desktop Virtualization is a crucial factor that will compel IT enterprises to support a significant increase in delay sensitive WAN traffic. In order to aid this situation service providers specializing in RDP remote access have introduced WAN optimization controllers with multiple features, that helps in:

 

* Minimizing the remote application response times by up to 95%

* Minimizing the network bandwidth utilization by up to 95%

* Is purpose-built to bring down the impact of network congestion, latency and packet loss that combines to significantly slow end-user response times

* The Application-specific WAN optimization blueprints and specific protocol optimization helps in reducing redundant, chatty protocol traffic

* Stream-based differencing averts transmission of content already in the local data store and the compression techniques minimizes the amount of data on the wire

* Is available in hardware and virtual appliance form factors, that helps to achieve ROI within a less time frame

* Supports 50% more speeded up connections

* The virtual appliances make use of minimal system resource, can stay with other applications and scale linearly with the addition of CPU cores, memory and disks

* Helps in easier management of virtual and physical deployment, transparent addressing, statistical performance dashboard and auto discovery

* Offers centralized provisioning and management by incorporating with Virtualization management systems

 

Furthermore, advanced WAN optimization controllers make use of a combination of application acceleration, packet compression, network acceleration, protocol optimization and caching to speed up the applications and minimize the expense of delivering applications across wide area networks.

Business Continuity Planning -Safety In face of Adversities

Every business irrespective of being a small and medium one or a large conglomerate is a profit oriented one. Technological innovations deployed in the business environment aids in globalized expansion of the business and leads to revenue generation and increased profits. However, any disruptions either minor or major may have serious impact on the day-to-day business operations.

Foreseeing business disruptions or the time when disaster strikes in an unknown factor and the globally bound organizations today are faced by the challenge of maintaining business continuity in face of all storm. Business continuity planning is one of the main strategies taken up by the global organization. Spread across geographical boundaries and remotely distant locations, these organizations need to be ready to face any disruptions in the business operations while ensuring that work goes on without any serious impact.

Business disruptions may result from various reasons such as epidemics, transit strikes, cyber-attacks, natural calamities etc. Under such circumstances a detailed remote access strategy and business continuity planning (BCP) will help the global enterprises to deal with emergency situations and help them to avoid loss of productivity or revenue. The remote access solution must be one that would help enterprises with:

* Secure anytime, anywhere access leading to uninterrupted business continuity
* Maximum performance, automated VPN provisioning
* Cost-effectiveness and global redundancy

A continuous delivery of critical services and products, demands that organizations need to have the facility that permits them to recover data, application and assets in a real-time access mode. As Gartner's analyst suggests that the most critical success factor to any business continuity plan is fast re-establishment of business processes. However, if the disaster recovery plans do not include Remote Desktop Access, no amount of technology can save business operations. Hence the real-time access to information will facilitate the employees to continue work from any location, allow business partners and suppliers an uninterrupted access to important information. Such actions will minimize the disruption levels of business processes and applications.

With large number of vendors offering business continuity planning solutions, enterprises need to make the most of the benefits to ensure productivity at all times. The enterprises needs to decide on appropriate ones and service types required for the business environment. The availability of applications from the corporate network and remote desktop access will help mitigate business disruptions. Application availability solutions from leading service provider’s offer load balancers and WAN optimization controllers for any fail-over for WAN links, devices and data centers.

However, the enterprises need to ensure that anytime anywhere remote access to business critical information also poses issues of data and network security. Thus service providers of business continuity planning solutions also need to ensure that the corporate network are equipped with secure access gateways that can support multiple access.

Load Balancers And Their Role in Global Environment

A technological innovation over the period has facilitated the business enterprises with digital workspaces. The corporate offices work through highly networked environment and use large number of software applications for the day-to-day operational requirements. Further with globalization, these enterprises have also expanded globally with distantly located regions. However, real-time connectivity between all the far-off offices and remotely working project teams are maintained with the help of dedicated servers.

The technological enhancements further made it possible for the offshore teams, outsourced vendors and remote workforce to access the corporate network irrespective of the distance and device. Such anytime anywhere access to the various applications, files and folders from the office workstation and business critical data and information taxes the servers and the network when loaded with increasing demands. Added to this the BYOD apps available only increases the load on the servers and clogging of the network leading to reduced speed and performance. Under such circumstances, load balancers help the enterprises in easing out the situations.

Load balancers are generally used in heavy traffic laden computer networks like the Internet and corporate networks of multinational companies. Defined as a computer networking methodology load balancing helps to distribute the workload across multiple resources to achieve optimal utilization with maximum throughput, and minimum response time. , and avoid overload. Dedicated hardware, software and servers carry on these functions. The software program helps to track the front-end client’s access services and forwards requests to the back-end servers to enhance website performance as well as reduce the burden of a particular server.  

Further with most of the global enterprises having distantly located project teams working either in offshore locations or forms a part of the mobile workforce, providing them with remote desktop access and to the corporate data becomes very important. Networks of large corporate houses or small and medium enterprises or data centers with vast amount of data and application storage and transfer resort to use of load balancers.

For the new age enterprises load balancers  offers essential benefits such as:

●  Minimized load on individual systems with reduced response time
●  Maximum network utilization
●  It enhances reliability and improves user satisfaction.

However, with issues relating to web securities, the load balancers intelligently routes the hypertext transfer protocol traffic to servers which are involved in controlling access to websites. Besides these also scan the traffic for any spyware, phishing attacks and malicious components entering the network thus ensuring an efficient system of business continuity planning.

Optimize Data Transfer Efficiency with WAN Optimization Controllers

WAN Optimization Controllers are appliances that optimize data-transfer efficiencies across a wide area network (WAN). It is a collection of techniques that optimize bandwidth to improve the end user's experience. WAN optimization controllers use a combination of techniques such as compression, latency optimization, forward error correction, caching / proxy, deduplication, traffic shaping, application acceleration, network acceleration equalizing, protocol spoofing, connection limits, simple rate limits to accelerate applications and reduce the cost of delivering applications over wide area networks.

Normally enterprise users experience great performance when using applications and services over a LAN. However, they face problems when accessing remotely the same applications and services over the WAN. Accessing applications across a WAN introduces network congestion, latency, and packet loss that can dramatically slow remote end user response time. Many IT organizations increase their spending by adding more network bandwidth to address these issues, only to find that poor application response time over the WAN has not changed. Moreover, with the addition of Virtualization, many enterprises are consolidating servers into corporate data centers. However, the consolidation of applications out of the branches and into the data center puts even more strain on the corporate WAN. In some cases, this degrades end user response time even further. That is where WAN or network optimization appliances come useful. The following are some of the benefits of using the best of breed WAN optimization controllers.

* Reduces remote application response times by up to 95%

* Reduces network bandwidth utilization by up to 95%

* Purpose-built to reduce the impact of network congestion, latency and packet loss which combine to dramatically slow end-user response times

* Application-specific WAN optimization blueprints and specific protocol optimization eliminates redundant, chatty protocol traffic

* Stream-based differencing avoids transmission of content already in the local data store, while compression techniques reduce the amount of data on the wire

* Window resizing, persistent connections and small packet aggregation dramatically improve overall TCP performance

* Supports 50% more accelerated connections as compared to alternative appliances

* Virtual appliances use minimal system resources, can reside with other applications and scale linearly with the addition of CPU cores, memory and disks

* Enables easier management of virtual and physical deployment, transparent addressing, statistical performance dashboard and auto discovery

* Provides centralized provisioning and management through integration with Virtualization management systems

Thus by deploying WAN optimization controllers, enterprises can ensure a premium application experience for all users and achieve rapid ROI by lowering overall bandwidth costs.
