Some Important Points to be Taken Care of Before Dealing With the Web Hosting Plans and Its Services?

31.12.2010 (5:32 pm) – Filed under: Uncategorized ::

One should act very smartly or can say intelligently while making decisions regarding web hosting services and plans. One who is serious for his/her business can suffer later on, if his/her decision of choosing web hosting went wrong. Due to inefficiency of the web hosting plan one can face loss by decreasing of sales as well as loosing the customers. One should not make decision in haste while choosing the web hosting plan rather he/she should study all the options and compare all the advantages as well as disadvantages, then make the decision accordingly .If the decision is made after studying every aspect then only it will prove very fruitful for the business.

What are the requirements of the user? A Personal Home Page or a Business Site Hosted

Before moving further the user should be very clear about his/her requirements and one of them is what type of the website he/she desires and want to have hosted. User should choose the plan as per his/her needs as if the user is running a small business then he/she does not require the larger hosting plans. If the user is going to plan on having a large ecommerce site hosted, then small hosting plan will not fulfill his/her obligations and the user have to move for the web hosting services providing all the bells and whistles. After deciding about the type of website one can easily host and compare all the services and plans and then can opt for the most suitable one.

Amount of Data Transfer And Disk Space Offered From The Web Hosting Plan:

While deciding about the plans, user should be very clear about the disk space and bandwidth he/she requires and then compare all the plans and choose the hosting plan that can easily manage the data transfer from his/her business promotions that can cause large amounts of traffic. This is very clear to the user that if he/she is going to deal with a simple home page then he/she will not need much disk space and bandwidth. When the user is clear that what he/she actually requires from the web hosting service, options and plans, then only he/she is able to make decision.

Web hosting needs should be considered earlier:

The points to be considered by the user of the web hosting services are, the cost and fees, customer support, control panel, POP email accounts, FTP transfer limits and if the user have unlimited space transfer.

Economic factor: Cost of Web Hosting and Possible Setup Fees?

Economic factor matters a lot for all kind of users as every one want best services at the most reasonable price. The user should be well aware before paying for the services as he/she should know that what he/she is paying for.

Before signing any hosting plan user should look at the support provided by the company to the customers .Customer support is very important aspect which can not be ignored as customer can need the company’s support any time. If customer support is not provided at proper time then in result his/her site will remain down for long periods of time. A company is said to be a reliable company if it is able to provide the support service of 24 hours a day customer support. User should also study about the experience of the company and also the support provided to its customers. User can easily check with the references to see how the web hosting company rates with customer service. If customer is aware of all these aspects it will be very helpful for him/her for making decision and can save himself/herself from the time and money loss.

Services available -Is Control Panel Available or not?

The new entries in this web world don’t have proper knowledge and much experience with web hosting control panels. Due to this reason they can suffer from severe problems many times. So before moving to any decision the user should collect all the complete information such as-

1. What type of control panel the web hosting service offers?

2. Is it user friendly or not?

3. Last but not the least that it suites all the requirements?

Control panel is not required by an experienced webmaster may not need a control panel, but it is necessary for rest of the users.

What about the availability of POP Email Accounts?

There are some other aspects as well which user can’t afford to miss. One such aspect is POP email accounts being offered by the provider. E-mail service is the service that is needed by many business plans from their web hosting plan. User should look out for the availability, if he/she desires access to email accounts.

Plans offering FTP Transfer limit as per requirement:

User should be sure enough about the FTP transfer limits with the web hosting services he/she is going to opt for. User should also watch out that the web hosting plan he/she is choosing offers FTP transfer according to his/her business needs. He/she should save himself/herself from those web hosts that do not have unlimited FTP use.

Some more things to be known by the user about the web hosting plan are:

1. Does they offer unlimited space transfer?

2. What are the terms of the services regarding upgradation?

3. Availability of the space if more needed in the future.

If the user does not look out for the terms of the space availability in its web hosting service then he/she can suffer from the problems regarding space, as if the user needs more space later on he/she will not be getting it.

User is able to make the proper decision of choosing the web hosting service only after having the complete information of each and every services provided by the web host.

Police Career – Linux Computer Systems in Law Enforcement

29.12.2010 (5:37 pm) – Filed under: Uncategorized ::

Law enforcement recently has been following the general tide of government and public service groundswell by seeking computing solutions in the Linux direction. Particularly in law enforcement, their needs match well with open source software. They have to work lean on a taxpayer’s budget, and open source is free or low cost. They need top security, and Linux is still the highest-scoring operating software in official government assessments. They need mission-critical reliability, and Linux is so stable, it doesn’t just outrank the competition in stability – it makes the competition disappear!


Some recent examples of law enforcement agencies finding a solution in open source:


* Kent Police have lowered the cost of running their major criminal investigations system by a factor of 90% using Novell Linux Open Enterprise Server. The migration to Novell enabled Kent to scale up their Holmes II investigation system to work on larger projects with a broader scope – something they’d never been able to do before. They were also able to run it on their cheapest hardware they could find, thanks to Linux’s light requirements. A new policing operating system, named Genesis, is now being tested for scalability on Linux servers.


* Delivery of the first Linux systems to the West Yorkshire police force could see police forces throughout England and Wales unanimously switching to Linux desktops in a new pilot scheme. The deployment is taking place under a contract awarded by the UK Police IT Organization. If successful, it will lead to over 60,000 desktops deployed. In West Yorkshire alone, the installed base is around 3,500, and a spokesman reckoned that the savings from this would be around one million pounds per year!


* The New South Wales Police department is currently undertaking a major upgrade to its information infrastructure, made necessary due to the increasing volume of data handled by the force, and they’re switching to Linux systems to handle the load. Because the Linux systems are proving so reliable, they are looking forward to the higher capacity network more efficiently archiving and transmitting data stored as evidence, such as surveillance videos and audio material.


* Scottish police forces have also developed a Linux-based system for ensuring that they comply with the Freedom of Information Act legislation, an act which is intended to facilitate ‘open government’ by allowing the public to request access to government data. Since open source and open information go hand in hand, the system has scaled easily and saved tons of labor. The force doesn’t have to worry about proprietary media formats interfering with the public’s ability to access the data, and the efficiency of the Linux system allows a lot of manual tasks to be automated where they couldn’t before. The system is literally returning officers to the streets because it has saved everyone so much work.


* Police in the city of Munich have switched 14,000 of their department computers from Microsoft’s Windows operating system to Linux. The motivation for the decision was to make the government less dependent on one information technology supplier, and to save money while increasing capabilities. One technology analyst even compared the break-through migration to the fall of the Berlin wall, referring to the oppressive requirements of dealing with a proprietary software company’s agenda.


That government feels friendly with open source should come as no surprise. Traditionally, the Internet has been 80% Linux and Unix-based systems since its creation. The first Internet services were started and maintained by government providers, who used Unix system’s built-in multitasking features and excellent speed to create a fast, reliable network. Linux, a modern version of that Unix ideal, has already established itself as the leading system for server-room deployment, but now the effects are beginning to trickle down to the desktop user level and workstation deployments, where they are discovering that Linux systems have workspace-ready features built in which other commercial operating systems are just now beginning to discover and implement.


Furthermore, Linux systems come with the guarantee that because they are open source, no commercial company can restrict their usage in the future. A platform ported to Linux can stay on Linux, without support dying out and constant upgrades creating problems down the road.


Finally, the inherent security of the Unix computing model guarantees the effectiveness of Linux without the worries over security problems. Because there are in effect no viruses which can infect a Linux system known, and no critical security exploits found in the systems even by government security standards, departments are also considering Linux as a measure to protect our national data under concerns over national security and the terrorist threat in our modern times.

5 Reasons Businesses Utilise A Virtual Server To Supply Their World Wide Web Presence

28.12.2010 (5:34 pm) – Filed under: Uncategorized ::

Virtual servers work great for the web developer that is short in the pocket. Although Linux virtual servers and Windows virtual servers are the most popular, virtual servers come in many different forms.

Voice servers are a popular choice for VPS hosting. Voice server hosts need to offer services all over the world in locations such as London and several places in the US. Thus, virtual servers work perfectly. The cost of renting several dedicated servers can soon add up. A VPS can be rented at a fraction of the cost of a dedicated server.

Website hosting is the most popular choice for virtual hosting. Particularly for specialist companies that don’t quite need a dedicated server. A VPS will have redundancy in the form of a raid array and memory and CPU as and when you need to upgrade. Those that just want to host a couple of websites also take a VPS as an option.

Social media apps are jumping on the virtual hosting bandwagon. Those Facebook addicts will be familiar with such apps. Facebook applications are all the craze. You can do everything from managing an army, to a record company! Again the benefit for developers is they can host these applications on a virtual hosting environment without the need to opt for an overkill dedicated server environment.

Databases make use of virtual hosting. Never have all your eggs in one basket. Using a VPS keeps databases offsite and safe.

Virtual hosting is very often used for DNS. I recently setup a backup DNS server at the fraction of the cost. Our main DNS is hosted onsite, but the secondary offsite. In the event our services go offline, we still have an NS2 that will serve DNS from a different network, and a different datacentre. This allows for total service!

We have identified the 5 main uses for virtual servers above. If you can add any weird and wonderful things you have utilised them for, please do let us know below.

What You Really Need to Know About a Dedicated Windows Hosting?

27.12.2010 (5:33 pm) – Filed under: Uncategorized ::

There ar two kinds of web hosting the first is shared. That is the highest common. It essentially takes sharing server place with lots or 100′s of different web sites. The bandwidth, storage space and memory are all split ‘tween the companies using that certain server. For nearly all webhosting providers that is more than plenty.

The 2nd sort of hosting is dedicated hosting. This entails the server storage, RAM and monthly traffic come with the server are all for a 1 businesses apply. It normally goes with a dedicated IP address. These types of hosts are high-ticket but deserve it if there is a require for the space, memory and monthly bandwidth.

There are a list of various platforms that may go used when it moves seeing the software application programs that ar getting to be operate on or function the hosting server. The server is just a specified pc, in many cases it doesn’t need anything expensive to go run as a hosting server still you do desire to think the running system utilized on this equipment because it shapes various agents.

It controls stability, scalability, and in many types what will be interfaced with it. It as well regards serving speed. Programs include Windows, UNIX and Linux. Of these Windows is going to be the easiest in regards to user interfaces, and the ability to interface. 1 reason is that Windows is made for usability on the clients end. The majority of people looking at dedicated hosting services take dedicated windows hosting as an upper consideration.

There’re an amount of things to think of if it arrives to determining if a dedicated server is worth the financial investing. It’s not for everyone. It may also mean large changes for your business sector. The claim for a dedicated hosting server normally signifies you are on the right path, winning clients, business sector, bandwidth and hopefully profit on the way.

The internet is always becoming contributing recent and different communications protocols, languages, interfaces, and characteristics. Websites at present don’t seem complete without video, RSS feeds, wireless device adaptability, downloadable productions, servicing and characteristics. The net is planned for the public on the go and Windows system is universally accepted by 99% of software system application programs and protocols published.

If taking a big step such as choosing a dedicated hosting server and everything that accompanies it. It’s main to keep in brain that you must go by a name you rely and a production you have in which you have got faith. You need to be capable to make the product or servicing and move with it. The like goes for the web hosting provider you pick out to address the host. You will desire a service provider that is running to offer you with dedicated windows hosting to put up everything you and your developing business sector demands. They should be tried, good and fair in all aspects of job.

1 of the most tested webhosting companies is inmotion hosting which I mainly advocate. inmotion hosting offers the cheapest deal and offers great solvents for you if you would wish to turn for an capital serving, support and dependableness.

Ubuntu Linux is Prime Time for your Business Desktop and Notebook Computing Environment

24.12.2010 (5:42 pm) – Filed under: Uncategorized ::

As a business consultant, web designer and photographer my technical know-how around doing system administration on my Microsoft desktop is limited and sometimes I do require the assistant of my computer engineering son to get it right. In a Microsoft Environment, keeping updated with respect to potential security breaches and patches is a constant vigil. The rigor of keeping current with OS updates, Norton updates and Spyware updates is time consuming. Valuable business hours each week are spend and lost on this task of self-administration dictated by the Microsoft Operating Environment.

So with the purchase of an IBM T40 (a tough notebook), increasing system administration time was not an option. This alone forced an serious consideration of Linux as an alternative operating environment. That was five years ago. Now an established Linux user, I can clearly profess the capabilities and benefits of Linux for small and large businesses, especially, when it comes to notebook deployment.

What Linux variant is best for small business and notebook deployment in your company?

As a small and medium business development manager with Sun Microsystems, exposure to Linux and the debate around its viability was a daily event. Questioning and challenging the virtues of Open Source (FREE) Linux versus Licensed Linux versions like Red Hat and Novell SuSE continues to this day . After years of personal use of Open Source (Free) Linux, I can never go back to running the Microsoft Operating Environment on my notebook. And once you can get Linux versions of Quick books, Quick Tax and Picasa (now available on Linux), there is no reason to stay in that perpetual administrative nightmare world of Microsoft.

Having successfully deployed two Open Source Linux variants on my IBM T40 notebook over the last 5 years, a compelling comparison can be made between Fedora and Ubuntu. Fedora, the Open Source version of Red Hat, required the installation expertise of some Linux gurus from Belleville Ontario. It worked fine, but required some Linux ninja system administration every 6-9 months. Administration items applied during these visits included upgrades to Open Office (the open source version of Star Office), Linux OS fixes and new peripheral drivers. This, again, turned out to be a drain on my scarce time for doing real business.

Now the Linux called Ubuntu is installed on my notebook. Ubuntu by Canonical is a full Open Source Linux based on Debian Linux. Ubuntu is now available on Dell systems and Federal Governments are adding this Linux operating environment to their list of standard available OS’s for all desktop and notebook computers.

Right out of the gate, Ubuntu was simple to install. You could even bring down a trial copy to experience exactly how it would behave on your notebook before downloading and committing the Ubuntu OS environment to your machine. But the best part is that Ubuntu continuously keeps on top of OS and all related application software updates. Ubuntu has an Update Manager that magically appears in desktop tool bar. And with a simple click (and password) you are kept current on the latest versions of Ubuntu patches, any Linux application software you have installed from Canonical and Open Office upgrades.

With Linux rebooting your machine after an update is nearly non-existent.

Oh, as an added treat with Ubuntu, Ubuntu boots up on your machine in less than a minute. I still go get a coffee when my Microsoft desktop is booting up. An additional benefit of Ubuntu: there is no requirement for installing ant-virus and anti-spyware software. Ubuntu inherently repels these vial scourges of the internet.

With Ubuntu your system administration life will become simple and painless. You can spend more quality business hours selling and marketing.

Want to cut hidden costs in your organization that manifest themselves as Microsoft self-administration by your end users?

Ubuntu is a must for you or your IT folks to consider. Seriously consider, test and deploy.

The Data Center Temperature Debate

23.12.2010 (5:43 pm) – Filed under: Uncategorized ::

Though never directly articulated by any data center authority, the prevailing practice surrounding these critical facilities has often been “The colder, the better.” However, some leading server manufacturers and data center efficiency experts share the opinion that data centers can run far hotter than they do today without sacrificing uptime and with a huge savings in both cooling related costs and CO2 emissions. One server manufacturer recently announced that their rack of servers can operate with inlet temperatures at 104 deg F.

Why does it feel the need to push the envelope? The cooling infrastructure is an energy hog. This system, operating 24x7x365, consumes a lot of electricity to create the optimal computing environment, which may hover anywhere between 55 to 65 deg F. (The current “recommended” range from ASHRAE is 18-27 C or 64.4 deg F through 80.6 deg F)

To achieve efficiencies, a number of influential end users are running their data centers warmer and are advising their contemporaries to follow suit. But the process isn’t as simple as raising the thermostat in your home.  Here are some of the key arguments and considerations:

Position:  Raising server inlet temperature will realize significant energy savings.

Arguments for:

Sun Microsystems, both a prominent hardware manufacturer and data center operator, estimates a 4% savings in energy costs for every one (1) degree increase in server inlet temperature. (Miller, 2007) A higher temperature setting can mean more hours of “free-cooling” possible through air-side or water side economizers. This information is especially compelling to an area like San Jose, California, where outside air (dry-bulb) temperatures are at or below 70 deg F for 82% of the year. Depending on geography, the annual savings from economization could exceed six figures.

Arguments Against:

The cooling infrastructure has certain design setpoints. How do we know that raising server inlet temperature won’t result in false economy, causing additional, unnecessary consumption in other components like the server fans, pumps, or compressors? Free-cooling, while great for new data centers, is an expensive proposition for existing ones. The entire cooling infrastructure would require re-engineering and may be cost prohibitive and unnecessarily complex. Costs from thermal-related equipment failures or downtime will offset the savings realized from a higher temperature setpoint.

Position: Raising server inlet temperature complicates reliability, recovery, and equipment warranties.

Arguments for:

Inlet air and exhaust air frequently mix in a data center. Temperatures are kept low to offset this mixing and to keep the server inlet temperature within ASHRAE’s recommended range.  Raising the temperature could exacerbate already-existing hotspots. Cool temperatures provide an envelope of cool air in the room, an asset in the case of a cooling system failure.  The staff may have more time to diagnose and repair the problem and, if necessary, shut down equipment gracefully. In the case of the 104 degree F server, what’s the chance every piece of equipment—from storage to networking—would perform reliability? Would all warranties remain valid at 104 deg F?

Arguments Against:

Raising the data center temperature is part of an efficiency program. The temperature increase must follow best practices in airflow management: using blanking panels, sealing cable cutouts, eliminating cable obstructions under the raised floor, and implementing some form of air containment. These measures can effectively reduce the mixing of hot and cold air and allow for a safe, practical temperature increase. The 104 degree F server is an extreme case that encourages thoughtful discussion and critical inquiry among data center operators. After their study, perhaps a facility that once operated at 62 deg now operates at 70 deg F. These changes can significantly improve energy efficiency, while not compromising availability or equipment warranties.

Position: Servers are not as fragile and sensitive as one may think. Studies performed in 2008 underscore the resiliency of modern hardware.

Arguments For:

Microsoft ran servers in a tent in the damp Pacific Northwest from November 2007 through June 2008. They experienced no failures. Using an air side economizer, Intel subjected 450 high density servers to the elements—temperatures as high as 92 deg and relative humidity ranges from 4 to 90%. The server failure rate during this experiment was only marginally higher than Intel’s enterprise facility.  Data centers can operate with a temperature in the 80s and still be ASHRAE compliant. The upper limit of their recommended temperature range increased to 80.6 deg F (up from 77 deg F).

Arguments Against:

High temperatures, over time, affect server performance. Server fan speed, for instance, will increase in response to higher temperatures. This wear and tear can shorten the device’s life. Studies from data center behemoths like Microsoft and Intel may not be relevant to all businesses: Their enormous data center footprint is more immune to an occasional server failure that may result from excessive heat. They can leverage their buying power to receive gold-plated warranties that permit higher temperature settings. They are most likely refreshing their hardware at a more rapid pace than other businesses. If that server is completely spent after 3 years, no big deal. A smaller business may need that server to last longer than 3 years.

Position: Higher Inlet Temperatures may result in uncomfortable working conditions for data center staff and visitors.

Arguments for:

Consider the 104 degree F rack. The hot aisle could be anywhere from 130 deg to 150 deg F. Even the higher end of ASHRAE’s operating range (80.6 deg F) would result in hot aisle temperatures around 105-110 deg F. Staff servicing these racks would endure very uncomfortable working conditions.  Responding to higher temperatures, the server fan speed will increase to dissipate more air. The increased fan speed would increase the noise level in the data center. The noise may approach or exceed OSHA sound limits, requiring occupants to wear ear protection.

Arguments Against

It goes without saying that as the server inlet temperature increases, so does the hot aisle temperature. Businesses must carefully balance worker comfort and energy efficiency efforts in the data center. Not all data center environments have high user volume. Some high performance/supercomputing applications operate in a lights-out environment and contain a homogeneous collection of hardware. These applications are well suited for higher temperature setpoints. The definition of data center is more fluid than ever. The traditional brick and mortar facility can add instantaneous compute power through a data center container without a costly construction project. The container, segregated from the rest of the building, can operate at higher temperatures and achieve greater efficiencies (Some close-coupled cooling products function similarly).

Conclusions

The movement to raise data center temperatures is gaining but it will face opposition until the concerns are addressed. Reliability and availability are at the top of any IT professional’s performance plan. For this reason, most to date have decided to error on the side of caution: to keep it cool at all costs. Yet, higher temperatures and reliability are not mutually exclusive. There are ways to safeguard your data center investments and become more energy efficient.

Temperature is inseparable from airflow management; data center professionals must understand how the air gets around, into, and through their server racks. Computational fluid dynamics (CFDs) can help by analyzing and charting projected airflow on the data center floor, but as cooling equipment doesn’t always perform to spec and the data you enter could miss some key obstructions, onsite monitoring and adjustments are critical requirements to insure that your CFD data and calculations are accurate.

Data centers with excess cooling are prime environments to raise the temperature setpoint. Those with hotspots or insufficient cooling can start with low-cost remedies like blanking panels and grommets.  Close-coupled cooling and containment strategies are especially relevant, as server exhaust air, so often the cause of thermal challenges, is isolated and prohibited from entering the cold aisle.

With airflow addressed, users can focus on finding their “sweet spot”—the ideal temperature setting which aligns with business requirements and improves energy efficiency.  Finding it requires proactive measurement and analysis. But the rewards—smaller energy bills, improved carbon footprints and a message of corporate responsibility—are well worth the effort.
