10 Ways To Maximize Your IT Resources

Utilizing the capacity of the available resources within an IT organization is by far the most intriguing yet challenging task. However, the idea of maximizing the IT resource of an organization is gaining momentum, as the concept of cost cutting is intrinsically associated with it. Maximum use of available resource means minimum wastage and this can definitely help an organization to trim production cost to a certain extent. A structural and systematic approach in this regard can prove extremely effective. Making proper analysis, pinpointing the areas of redundancy, consolidating the available resource etc are some of the areas that should get the center of attention if you really want to usher a radical change the way IT resources are being utilized in your organization.

 

Create A Strategy:  Creation of a strategy is the first stage towards maximizing your IT resource. Without having a clear understanding of the available IT resource and their current position in your organization, you will never be able to make a difference.

 

Find The Relation: This is another important thing that you can only ignore at your own peril. As various IT resources are closely interrelated and interconnected with each other, you need to have an overall understanding of the interconnectivity among different IT resources before making an attempt to make any change. A wrong move in this direction can lead to a serious problem.

 

Assess The Potential of An Employee: Employees are the most valuable resource for an IT company. As IT industry is flourishing, people with little knowledge or little productivity often get more than what they actually deserve. This is a sheer wastage a company’s IT resource. Try to recruit people with high level of productivity as far as possible.

 

Consolidation of Resource: By transferring the ownership from individual business ownership to either an internal IT department or to a service provider can help you a lot to get things under control and this will obviously prove helpful for you to maximize your IT resource.

 

Data Center Optimization: It is the near perfect process for maximizing an organization’s technology resource through a multi-layered approach. Reducing redundancy and ensuring flexibility seem somewhat contradictory but in order to achieve a sustainable growth, you need to blend them harmoniously by designing and implementing a unique storage environment, cooling system, server networking and effective power supply in your data center.

Server Virtualization: It is a crucial component of data center optimization, which revolves around the concept of running a number of different virtual operating systems on a single computer independently. The main advantage of using this technique is that it allows a user to exploit the physical resources of a server to its fullest extent.

 

Power and Cooling Management: Energy efficient system is all you need to have in order to limit downtime of a server and to cut down maintenance cost. You can reduce the power consumption of your data center by ensuring the fact that the systems are running in perfect order and by placing the cooling mechanisms in a place where it requires the most.

Therefore, you will not have the face the complexities of having multiple data storage systems, as it can store data automatically.

 

Storage Area Networks: Storage Area Networks, which is popularly known as SANs, can ensure high performance of applications and servers within a data center by providing high speed connectivity and by maximizing performance of the resources.

By following these ways, you would be able to maximize your IT resources as far as possible. 

 

15 Ways To Ensure You Are Getting The Most Protection Out Of Your Firewall

 

 

Allowing authenticated communications and denying unauthorized access to a computer system or network are what the firewall of a computer does. To be precise, firewall is a device or a set of devices that is designed and configured for allowing, disallowing, decrypting or encrypting computer traffic based on the rules and regulations set by the administrator. In short, the main objective of using firewall within a computer network is to bolster the network security by thwarting unwanted or unsecured access that could cause security breach, service denial or data corruption. The ambit of firewall security entails determining network vulnerability and ensuring security. Firewall, which can be either a software program or hardware device or a combination of both, can act as a powerful tool to beef up network security. A number of protective measures can be adopted for reinforcing your network security by using some widely used techniques that are described in details below.

Packet Filtering Firewall: Blocking or unblocking traffic to a computer network is the main task of a pocket filtering firewall. A number of different firewall security techniques are being implemented for ensuring 100% security.

Intrusion Prevention Technique: In addiction to firewall security, you need to have intrusion prevention technique for differentiating authorized access and unauthorized access. This is absolutely a necessity in this type of firewall security system as it is extremely susceptible to web-based attack owing to its inability to prevent unwanted intrusion.

Stateful Firewall: This type of firewall is somewhat similar to that of packet filtering firewall but it has some added advantages over it. It is much advanced in drawing a fine line of difference between unauthorized access and authorized access.

Checking The Authorities of Packets: Here you will be able to instruct the firewall system to allow those packets, whose authorities have already been checked. However, this system still has some shortcomings. It is highly effective in preventing intrusions or pinpointing external or internal threats. 

Deep Packet Inspection Firewall: Its functionality is more or less similar to that of intrusion prevention technology. It can foil the attempt of breaching the network security by examining the security issues related to application layer attacks.

 

Pinpointing The Shortcoming of Deep Packet Inspection Firewall: The first thing is that this application firewall does not check the entire packet thoroughly. Therefore, there is a greater possibility of missing out some threats. Lack of processing power can make your network venerable to different external threats. 

 

Application-Aware Firewall: This is somewhat better and safer than deep packet inspection firewall. Here, the firewall application is powerful enough to parse some protocols itself. Therefore, it is extremely flexible and allows greater control over various aspects of network security.

 

Making Protocols Specific and Precise: However, the networking protocols have to be precise, specific and comprehensive at any cost. One more thing, its threat detection technique is not as robust as other type of firewall protection technique as it is not enough to face the challenges of real-world traffic.

Application Proxy firewall: In this type, all the access to the network has to be validated and intercepted before parsing them. In order to make your application proxy firewall effective, you should make sure the fact that it can parse the protocol set by the administer precisely. However, it is a bit difficult to implement an application proxy.

 

Protect Your network From Spyware: Spywares are potential security threat to any computer networking system. You should make sure that your firewall system is capable of detecting potential threats that can be caused by Spyware or malwares.

 

Application Gateway: This can prove extremely effective in consolidating security of your network but it can have negative impacts on the performance level to some extent. Here, a security mechanism is being developed for Telnet, FTP servers.

 

Circuit-Level Gateway: This is all about using and applying a security mechanism whenever, UDP or TCP is established in your network. Packets can flow unchecked if the connection can be established by using this mechanism.

 

Using a default-Deny policy: It is vital for you network security. The default-deny policy of your firewall should be capable of denying access of both unauthorized external and internal access.

 

Using a default-Allow policy: It is another vital thing that can play pivotal role in determining the future security of your network.  It should allow those accesses that are proved to be secure and safe.

Be Aware of Spam: Make sure that your firewall can detect junk mails or spam mails. They can cause serious problems if left unheeded. Clicking any outbound links of those junk mails can cause a breach in the network security system. So make sure that your firewall can detect and delete them as far as possible.

 

 

Can A Data Center Be Hundred Percent Green?

The term “green data center” is ascribed to those data centers, which are extremely energy efficient and are environment friendly. Computer, electrical, lightening and mechanical systems of these data center are continuously monitored for reducing power consumption and for lessening its harmful impacts on our environment as far as possible. However, using cleaner and greener technology for running data centers is the most typical task. Continuous power supply to data center is vital for getting maximum performance and it has to be ensured at any cost. However, turning a data center hundred percent green is not a far-fetched idea any longer. Now it can be done by making some basic changes, which are described below:

 

Redesigning Cooling System of the Data Center
Cooling systems that have been deployed in most of the Data centers are based on the fact that its load spreads out uniformly. But the changing requirements have now outdated this concept. The use of energy and the required density of heat have doubled in the past few years and this has almost made it impossible for an organization to run a data center by using the same cooling technique. The existing flaws of an existing cooling system of a data center has to be revamped by blocking holes, using advance technology and by using proper air ducts.

Utilizing Full Capacity
It is fact that only 5 to 15 percentage of the total capacity of server application of a server is utilized at a data center. Power consumption can be reduced drastically by utilizing the total strength of each server by shutting down unnecessary servers after making a roadmap. If we can manage to utilize the full capacity of a server, the requirement of servers will also come down at a data center and this will definitely have an overall positive impact as far as the power consumption of a data center is concerned.

Optimal Placement
Proper installation and placement of cooling equipments play a pivotal role in making a data center green. Optimal placement of cooling equipments in a data center can reduce power consumption to some extent. We need to cut down redundancy whenever possible. We need to operate a data center based on the current need as oppose to the future requirements.

Adjustable Equipment
By implementing modular or scalable systems in data center, we would be able to supply uninterrupted power during pick hours without making any unnecessary disruption. Scalable system has proved extremely effective for centralizing computer power in a small space. As it occupies a small space in a data center, you will need less power to cool that place. Besides that, scalable system does not need huge amount of power for running and operating it. What is even more interesting about Scalable system is that, it also allows us to increase its capacity whenever power consumption of a data center increases.

Opting for Greener Power
Using alternative technology is probably the best way to make a data center green and eco friendly. However, the initial cost of using alternative source of power can be a costly affair but in the long run they might prove extremely cost effective. Generating energy from solar panel is a popular method of getting green energy. You can also opt for other sources of alternative energy such as heat pumps, wind energy etc but this also depends on their availability.

 

Using environment friendly construction materials, using sunlight, non-toxic insulation, low-emission carpets etc can also help a data center to reduce its energy consumption to a certain extent. Following these tips would enable us to enhance the energy efficiency of a data center and also to make it greener and environment friendly.

 

 

What is a Dedicated Server?

Unlike shared server in which web space is shared by a number of users, in dedicated server client reserves the sole right to use that space without sharing the allotted web space with any other user. As the Internet connectivity, hardware, disk space and bandwidth are not shared with anyone, user gets high-speed connectivity and much better service. However, the cost of using dedicated server is a cause of concern, as here the expenses have to be borne by a single person and not by a group of people. But it does ensure a certain level of service that is unlikely to be found in any other server-hosting package. Besides that, person or the organization, which will lease the entire server, can wield full control over a number of issues such as use of hardware, operating system and many more.

 

High Speed Connectivity

 

Use of dedicated server is gaining momentum because of its unparallel speed and amazing bandwidth. As a large amount of bandwidth is being used by a group of dedicated server providers, now users can enjoy lower volume based pricing which is certainly a unique of its advantage. In order to get similar kind of service i.e. high-speed connectivity, a huge amount of investment has to be taken place, which is certainly not viable from economic point of view.

 

Bandwidth Connection

 

Over the years, the demand of bandwidth consumption has increased a lot and this is spurred by demand of those organizations that are running complex business or that are running sophisticated shopping cart sites or e-commerce websites. As these types of business organizations need more security and more space to run their business smoothly, they are always looking for more bandwidth support. This is the reason why a radical shift is underway in case of bandwidth consumption as a vast majority of users are now opting for per gigabyte usage model as opposed to conventional per megabit usage model.

 

Network Uptime

 

Most of the dedicated service providers offer a service level agreement depends on the network uptime. In some cases, some dedicated server providers are also promising to deliver 100% uptime to their clients. Providing higher uptimes is now being made possible courtesy the use of redundant hardware. Using the connectivity of multiple dedicated server hosting providers has also helped this to some extent.

 

Operating System

Price, familiarity and availability are the three most vital issues that play a decisive role in determining the operating system of a dedicated server. In most of the cases Linux operating system is provided to the users free of cost, as it is an open source operating system. Apart from open source operating systems, there are some commercial operating systems available that can be used as the operating system of a dedicated server. One needs to pay a certain amount of money as fee on a monthly basis, if he wants to use the commercial version of Linux operating system named Red Hat Enterprise. Some other open source operating systems that can be used in dedicated server are: Debian, OpenBSD, NetBSD, FreeBSD, Fedora Core, CentOS etc.

 

Operating System Support

Different dedicated server plan offers different level of support for managing these operating systems. Vulnerability resolutions, patches, security fixes, updates etc are some of the issues that are invariably associated with the concept of operating system support. These supports unburden a dedicated server owner from managing the server properly and it also ensures a safe and secure connection.

 

Security

 

The main advantage of using dedicated server is to ensure 100% security of data. Dedicated hosting server providers maintain a high level of security for ensuring this vital issue. In an effort to beef up security system and to evaluate the vulnerability of data, they often employ software programmers to thwart the threats from spam attacks, virus and hackers.
