Ensure the Secure Running of Appliances with Effective Load Balancers

While dependable internet connectivity has become imperative, it is load balancing that helps in achieving a greater bandwidth. Load balancing helps distribute workload over two or more servers in order to achieve increased redundancy, scalability or security. It has specific significance in busy networks, especially when it is challenging to predict the number of requests that will be issued to a server. While it not only increases the performance of servers, load balancing leads to their optimal utilization while also ensuring that no particular server is burdened.

Load balancing spreads the work of your managed server among two or more servers, optimizing resources, and output and response times. If a server fails in any way, requests are routed to other servers as per a predetermined standard to eliminate downtime. In load balancing, security is always important. Load balancers normally bring with them the added benefit of hiding the network and servers that are behind the scenes doing the actual work for the requested service.

Requesting a map service from one URL (the load balancer) may actually be assembled from many different servers that were behind a firewall. Since only the load balancer is allowed to communicate through the firewall security is increased as there would only be one point of entry. Some load balancers also come equipped with some analysis capabilities to detect denial of service attacks and take preventative measures.

With the increase in the size of an enterprise, there is an increase in the strain on the databases, network servers, and other crucial areas. Especially effective for organizations that use multiple data centers and server farms, load balancing solutions monitor the workload of servers and help to direct users. Distributing the work load is important but being able to automatically detect and handle the failure and the recovery of back-end servers is crucial. Load balancers offer many different capabilities in this area. While some can only detect if the server is alive and on the network, others have very elaborate methods such as retrieving content from pre-determined web pages.

Depending on the hardware and organizational needs, it's important to speak with a reputable provider about implementing and customizing this solution to your needs. Each network faces different challenges and works within different constraints. Look for a service provider who can leverage parallel multi-core processing to cost-effectively drive industry-leading performance across a rich server load balancing and application acceleration feature set for unmatched total value of ownership.

Ensuring Enterprise Mobility with BYOD Strategy

The arrival of IT consumerization has brought with it tech savvy consumers with a multitude of new age devices and equally adept at handling the latest technologies. Further, the growth of Internet led social media has also made the employees closer to their mobile devices. Armed with smartphones, tablets and new-age laptops, today’s employees demand greater mobility and prefer to use their personal devices at work. Enterprises need to embark on such ventures and provide employees with the freedom at work.

The BYOD (Bring your own device) concept is simple as it sounds. However, allowing employees to use personal mobile devices at work, the organizations face a number of challenges. Being in a technologically enabled and cybercrime filled business environment, the enterprises need to enable access to business applications without exposing the corporate network and avoiding any data leakage. Further, enterprises also need to make the changes in the existing infrastructure and applications to provide employees availability and access to business applications.

In an attempt to provide a cost-effective BYOD strategy, enterprises will need to work out RDP solutions enabling easy access to their remote desktop through any mobile devices chosen by the employees. Further, with the help of proxy architecture and RDP over SSL, enterprises can allow for anytime anywhere access to the applications and also ensure that data will not leave the corporate network. Such solutions developed by the leading service providers will enable seamless mobilization of the applications used by the enterprise and will also eliminate the chances of data leakage.

Reports from the online business community Entrepreneur Country claims that a simple strategy as BYOD at work can boost employee morale. Further, based on a poll of more than 300 CEO’s of small and medium enterprises showcased an affirmative response to RDP remote access and BYOD as a means to position their organizations as a flexible and employee friendly one besides being an effective business continuity planning solution. With technological growth enabling mobility and accessibility to business critical data and native applications across the enterprise with smartphones or any other devices irrespective of the location the enterprises are at risk of overloading of the corporate network.

While the use of load balancer distributes the load over the network, the appliance-based solution which is enterprise owned takes full control of the IT infrastructure and ensures closure of corporate network to third-parties. However, connectivity to personal devices is encrypted over SSL and the secure proxy architecture eliminating data leakage and potential attacks.

The innovative appliance based remote desktop access solutions have paved way for BYOD to make significant inroads into the business world. Today, with large number of employees across the global environment already using their own technology devices at work, has provided enterprises solutions that supports mix physical or virtual desktops and applications thereby maximizing the ability of the existing infrastructure while reducing complexities.

Load Balancing: Making of an Efficient Corporate Network

Technological innovations has paved for the globalized organizations to be well connected through the Internet. With offices located across geographical locations and working during different time zones, these closely networked organizations communicates and uses a number of applications through their corporate network The Internet thus is the vital link for business continuity. However, the development of technologically sound applications to stand out in a competitive business world, tend to overload the corporate network.

To evenly distribute the workload of processing and service requests across the devices in the network, IT and networking professionals make use of a load balancer. These are dedicated software, hardware, or servers such as a multilayer switch or DNS server, form the critical components of a network, and carry out the load balancing. Wikipedia defines Load balancing as ‘a computer networking methodology to distribute workload across multiple computers or a computer cluster, network links, central processing units, disk drives, or other resources, to achieve optimal resource utilization, maximize throughput, minimize response time, and avoid overload.’ Besides, optimal distribution of load across servers in the network is necessary for maintaining a stable network.

For the fast recovery of data and information across the corporate network, enterprises tend to use two ISP links one as the primary one and another as backup. However, technological innovations have helped design link load balancing solution, which facilitates simultaneous use of multiple links, thus increasing bandwidth availability, performance and reliability while reducing costs. Through an intelligent traffic management system, the link load balancer handles the inbound and outbound network traffic. The link load balancing appliances performs real-time monitoring of wide area network connections and leverages this for efficient management of the bandwidth.

Load balancing is commonly used to spread out the Internet service from multiple servers, and commonly includes, web sites, large chat networks, and File Transfer Protocol sites, NNTP and DNS servers. The server load balancers are strategically placed to ensure availability, control, security and performance of enterprise applications, data services as well as the data center equipment. Enumerating the benefits of using server load balancers showcases applicant ready and advanced network traffic management ensuring best possible delivery of business critical applications and internet protocol services. Further, this facilitates to offload the web and application servers paving way for increased capacity and efficient performance. This also paves way for multiplexing of integrated TCP connection and HTTP processing leading to great improvement in application performance.
