How To Select A Reliable Web Hosting Company

To conduct a successful marketing campaign on the Internet, your website must be hosted by a reliable web hosting company. Selecting the 'wrong' provider can prove very costly along the line.

Below I detail a few important aspects of the selection process based purely on my own experiences over the last six years.

Since there are thousands of hosting companies in the web hosting market, naturally during your research you will encounter hundreds of web hosting resource sites loaded with numerous and sometimes bogus reviews and recommendations, consequently your research process must be very thorough.

First and foremost do searches in the major search engines such as Google, Yahoo and MSN. Simply enter terms like "Complaints about 'Your Potential Host's Name'" 'Hosting Reviews', etc.....You will find a lot of stuff regarding your potential host. Search for 'web hosting forums'; there are numerous such forums on the web that contain all kinds of information.

If you consistently find too many complaints about your potential web hosting company.... beware!

A company that offers too many features for too little is also suspect. If they are offering huge amounts of bandwidth and disk space for a very low price, be careful. Here is why: The company will most likely be forced to host numerous websites per server, resulting in congestion and server overload. The result: Your site may be too slow and may experience lots of downtime.

Where is your web host's datacenter located?

A datacenter located in a natural disaster prone and/or a politically unstable region is undesirable. I wouldn't host my website in a Kabul, Afghanistan or Kinsasha, Congo based datacenter - these two and many others around the world are politically unstable regions. On the other hand a datacenter based in the state of California, a major earthquake zone may be undesirable, but the fact that California is more than well equipped to handle such disasters and is the world's nerve center for all that is computer, far outweighs any existing dis-advantages.

A foreign based hosting company may be too far away from your customers. It won't serve you well if your host is based in Australia and your targeted customers are based in The United States. On the contrary, if your are marketing to customers exclusively in Australia from The United States, a web hosting company in Australia would be OK. If you are marketing worldwide, your choice becomes a little bit more complicated....unless of course you are Google, Yahoo or MSN, big companies who host their websites almost everywhere worldwide. Generally, I prefer web hosting companies located in The United States.

How is your web host connected to the internet?

Your potential host's data infrastructure - regional and local is of utmost importance.

- How is your potential host connected to the Internet...Do they have multiple connections to the internet backbone, and enough bandwidth to accommodate surges in web traffic?
- What kind of computer equipment is deployed within the datacenter?
- Is the latest network security technologies incorporated?
- Are the hosting servers protected behind firewalls and intrusion monitoring software
- Is the datacenter monitored via CCTV and supervised 24/7

How fast is your web host?

Find a couple of sites that are hosted by your potential web hosting company and test how fast their pages load on your computer. You also may execute the PING and TRACEROUTE commands on these websites to determine their suitability. Executing the ping command is called pinging a website and it determines how quickly a server can receive and send back a piece of data through your connection. When you run ping it sends a small packet of data and calculates the time it takes to get a response from the server. It is executed four times by default and a small report of average, minimum, and maximum response times will be displayed. A ping output typically consists of the packet size used, the host queried, the ICMP sequence number, the time to live, and the latency. All times are given in milliseconds. A ping output indicating large values and/or lost packets consistently over a period of time ....is a red flag! Please note that if you have a bad or restrictive connection (Your ISP), the results may be skewed. Firewalls and proxy servers installed in your system or network can sometimes interfere with the ping operation. Also, some web hosting companies do not allow pinging of their servers, in which case you will get a 'Request Timed Out message'.

The Traceroute utility displays the connection [path] through the Internet between your computer and the potential web hosting company's server(s). The path between these two locations has many routers, computers and other devices along it which help move Internet information. Each movement from one device to the other is called a hop. Too many hops is cause for concern ....do several Traceroutes for comparison!

Based on my experiences with different hosting companies over the years, I regard the following Web Hosting companies as the most reliable. I am sure there are many other good hosting companies out there, but it would be unfair to comment about a company that I have never dealt with.

One my websites, TheCertificationHub.com has been hosted by Ipowerweb since 2000. There were problems at first, typical when a web hosting company is experiencing a spurt in growth. In the year 2000, they had a customer base of 15,000. Six years later this number has grown to almost 300,000 and their service level has improved tremendously over these six years. Ipowerweb is one of the best web hosting companies on the Internet. A first class hosting company which I highly recommend.

I moved my other website, ClubAfrika.com from Globat to iPowerWeb beginning April 25, 2005. With Ipowerweb I have experienced much less frequent downtimes, few email delays and failures. The customer service is superb and well coordinated as expected. The only problem we had at the beginning was their inability to transfer our database from Globat. Club Afrika is targeted at users in Africa, most of who are still on dial-up. It therefore makes no sense that these users have to wait for 5+ minutes for pages to load up. In this respect Ipowerweb has delivered. My site is no longer 'snail slow' and in spite of a few incompetent TIER 1 Techs here and there, overally I am satisfied with their service. Globat may improve in future....I suspect that they are having 'growth problems' just like Ipowerweb had when I first started hosting with them. If they do, then they might be worth considering for they offer the most 'humongous' features in the web-hosting business. But be cautious, 'Greed' almost always translates into poor website performance....some of their offerings are just too good to be true, for lack of appropriate words.

I have been hosting another website, ApondoSystems.com on Lunar Pages servers since 2000. Lunar Pages web hosting plans start at 5000MB of storage and 400GB of transfer for only $7.95. It is my opinion that Lunar Pages is a great web hosting company. Great website uptime and customer service! Very few websites require more than 1000MB of disk space (Apondo Systems has over 300 pages and I haven't even used one half of the allocated space), so if what you are looking for is quality first, Lunar pages is a good bet. If you are looking for extra databases, humongous disk space and bandwidth, then take a look at iPowerWeb which is a topnotch company too, or even Globat.

StartLogic is a relatively new web hosting company, a reseller of IPowerweb Web Hosting Services. Naturally, you will expect them to follow in the great footsteps of Ipowerweb. Being the #1 reseller of Ipowerweb, StartLogic's hosting infrastructure is most probably maintained by Ipowerweb, a large and reputable web hosting company. They offer both Windows and Unix Hosting. Due to the 'newness' of the company and the fact that I have not used their services, I cannot judge them authoritatively, but based on the comments I have seen so far, all over the Internet and by virtue of their relationship with Ipowerweb, I think this is a good low cost web hosting company.

GoDaddy currently offers one of the cheapest prices for Domain Names and Hosting Services. The pricing on packages is very competitive. With Godaddy website templates you can get a nice-looking Web site with ample storage. Reports indicate that their performance is above average. One thing you may not like is that they do not have an 800 number for Technical Support. They prefer local numbers. I think their pricing especially for Domain Names is very reasonable and is worth giving a shot. Also, if you are looking for just a handful of features, Godaddy offers very flexible packages....they even allow you to pay for your hosting services on a monthly basis! The control panel is kind of 'tight', scripting Gurus may not like some of the restrictions but I think Godaddy hosting is worth a try. We hosted AfroArticles.com briefly at GoDaddy but quickly moved it to Hostgator for one and only one reason: Godaddy does not support CRON JOBS, a server feature vital to AfroArticles.com.

Our website, AfroArticles.com is hosted at Hostgator. We were initially attracted by two things: Unlimited Databases and the option of paying monthly and not the usual year long contract. This means that if we are to disapprove of their services during our self imposed trial period, we will be able to opt out with ease. Well, we haven't because we love the friendly and professional customer service support offered by hostgator and our website has been running exceptionally well. We have yet to experience any unscheduled downtimes. If you are looking to re-sell hosting, then consider Hostgator. Although the pricing is slightly above the average in comparison to other top hosting companies, we feel that the reliability of their services, the bandwidth, storage, unlimited databases and numerous other features included with their packages are well worth it. Hostgator is a topnotch hosting company, at the same level as iPowerweb and Lunar Pages.


Getting The Right Office Furniture For Computing

Having the right furniture in your office can not only help you to be more productive, but it can also provide the correct support for your body as well, especially if you spend a good majority of your time in front of the computer. And whether you’re at home or the office, you most likely know that there are proper and improper methods and heights for sitting while you work. But did you also know that the wrong office furniture can lead to Repetitive Stress Injuries that include chronic back and neck pain, carpal tunnel syndrome, eye strain and a variety of other health problems? Let’s take a look at the best methods for avoiding these issues.

Chairs
Sitting in an ergonomically correct chair is one of the best things you can do for yourself. The right chair should be easily adjustable to provide proper support for the small of your back and your lumbar curve overall. It should also be ‘user friendly’ so as to fit well with your body type. And when sitting, your feet should be comfortably flat on the floor or on a footrest in front of you.

Desk
Whether your keyboard sits on top of your desk or on a pull-out keyboard tray underneath it (which is actually the recommendation), it should be a comfortable level of between 27 and 29 inches from the floor depending on how tall you are. There should be sufficient distance between your shoulders and the keyboard so as to prevent any stress or strain in that area, as well as in your elbows and wrists as you type.

Lighting
The lighting you choose can greatly affect the quality the work you produce. The computer screen is quite bright in itself and adding even more intensity to that with the wrong lighting can cause headaches as well as eye strain. A good idea is to utilize a lamp that has a dimmer mechanism so that you can adjust it to your personal preference.

And don’t forget to take regular breaks from the computer! Sometimes we get so caught up in what we’re working on that we forget to do this. But getting up and stretching your back and muscles as well as giving your eyes a rest will greatly help you in the long run.


Want To Be A Web Host?

So you want to be a web host? Here are a few tips you could use to get the edge even if you’re starting out new. Start out with the right equipment. A lot of web host drop out of the race so quickly because they didn’t plan out their growth and match it with their operating resources. You’ve got to research, get tips from the best IT people, systems engineers, electricians, and other professionals and get the best telecommunications tested networking gears complete with back up systems to give solid assurance to your clients of continuous 24 hrs service even if you have do some maintenance of parts of your operation.

Back up systems kick in if you have some trouble with some of your servers and clients can continue to retrieve files when needed when there is a temporary system crash. Location of your equipments should be in relatively hazard free environments so these do not cause periodic operational failures for you. Most of your clients would be big businesses who are investing thousands of dollars to have their website hosted by you. So your reputation is at stake. Leading web hosting companies have a solid reputation and they invest heavily to keep their reputation spotless. When you’re starting out, you have to build your reputation from scratch. So be wary.

Clients expect to have the following as part of your services: reliability, bandwidth and speed of access. They don’t want to hear any feedbacks that their website is unavailable, is slow jumping from one page to another. The speed should be uniform for all hours of the day even during those times when the internet traffic is extremely heavy. Allowing for a lot of space for clients to grow whether for business or for personal use will also be important. Make sure that the bandwidth you offer is more than enough for all the types of clients. E-commerce and even some individual clients want to download different sizes of files, the less restrictions you have when it comes to downloading or uploading files, the better.

FTP or File Transfer protocol is an important part of web hosting and you should be ready to assist newbie on this by having a very responsive and patient customer support. A 24/7 online team is a must to answer any concerns of your clients. Some web hosts have a feature called a WEBDISK that allows them to hook up their computer files to the web host so that instead of looking for the files on their computer they use this feature which produces a copy of their computers actual files for easy copy paste maneuvers when they want to add content rather than uploading it from their computer.

If the clients will be needing extra features like video hosting, MP3 Hosting , image hosting make sure your system can provide such services without affecting your whole web hosting operation. It’s better to have a powerful server at the onset with a wide bandwidth. Your features including Pricing will always be an important factor.

Hybrid cloud computing technology

Hybrid cloud is infrastructure, which includes links between managed by the user Cloud (usually called "special") and at least a cloud managed by a third party cloud (usually called "public cloud"). Although the public and private sectors of the cloud, hybrids are linked together, they remain unique entities of its kind. This allows the hybrid cloud to provide the benefits of the deployment of several at one time Templates. Hybrid clouds vary greatly in sophistication. For example, some hybrid clouds offer only connection between the site and public clouds. All the difficulties inherent in two different infrastructure is the responsibility of operations and application teams.

Most of the mixed material is concentrated clouds, critics and infrastructure specialists. However, the company has affected parts of some of the most essential parts of a quantity of hybrid cloud: the abstraction layer for applications - when avoided, should not be relied infrastructure applications. Containers for Linux and Windows are the main means of extraction application infrastructure. It can also be designed to play a part of the resources allocated to reduce or eliminate the use of the controller amount of platform. When there is no API to use in conjunction with a third party criteria containers such as port workers and missiles, and applications are also the technological capacity of the PAA. Dissemination of political orientation - organizations must be able to deploy workloads based on programming policy. Part of the workload in the public cloud will be sent on the basis of risk and the development of the theater, while others will be posted internally. The application can also move back and forth depending on the desired results. For example, an organization may choose to use public cloud services for archiving its data, but it remains to keep the details of service to customers at home. It should be the policy of some developers access on request to multiple cloud computing services, such as data storage and selection public cloud providers and internal operations - catalog of services that focus on. Should be allowed to divide the specific development in the self-service bulletin. Application / Microservices support existing and new - must be new and the environment will not be exclusive to the new Greenfield operations and applications, but should not be excluded. Existing applications can and should take advantage of the scalability, flexibility, and other distinctive characteristics of the cloud. You must be new applications with advanced features of the cloud will be easier to build. You should start and other features help create the platform intelligent endpoint that can be used dumb pipes policies, the main objective of microservices

The idea behind the hybrid cloud is that companies can use to take advantage of the cost effectiveness and scalability offered by public cloud environment without critical applications and data weaknesses associated with the sensor that public cloud option. In addition, the hybrid cloud model creates is often the best most effective for different types of data can be transferred solutions to provide the platform for the most effective and safe environment.

Usually create a hybrid cloud in one of two ways: either the seller with the private cloud based solution provider is a partnership with the public cloud or public cloud provider and a partnership with the provider that offers private cloud platforms .
Can that many organizations reap great benefits of hybrid cloud option. For example, the company may want to use a SaaS application, but not concerned about security risks to a third party provider, such as Apprenda, and create a private cloud within the company for its firewall. Or a company that offers services tailored to different verticals can choose to use the public cloud to interact with their customers, but the data remains in the safe environment of a private cloud.

Définition What is hybrid cloud united state

Hybrid Cloud is a cloud computing environment that uses a mix of onsite, private cloud and public services cloud orchestration between the two platforms. To allow workloads to move between private and public clouds, and the needs and IT costs are changing, hybrid cloud offers companies greater flexibility and deployment options data.
For example, a business may implement a private cloud on-site to host sensitive or critical workloads, but the use of a third party provider such as Google Compute Engine public cloud hosting less critical, such as loading resources testing and development work. To maintain customer facing and backing up data files,
a hybrid cloud could also use the Amazon Simple Storage Service (Amazon S3). A layer of software, such as eucalyptus, private cloud can facilitate connections to public clouds such as Amazon Web Services (AWS).

Hybrid cloud is especially useful for dynamic loads or rapidly changing work. For example, an entry system transaction orders that are experiencing significant demand peaks around the holiday season is a good candidate hybrid cloud. The application can work in the private cloud, but the cloud burst use to access additional computing resources from a public cloud computer when peak demand. To connect the private and public cloud resources, this model requires a hybrid cloud environment.

Otherwise, use the hybrid cloud is the large data processing. One company, for example, could use the hybrid cloud storage to preserve their accumulated business, sales, testing and other data, then execute analytic queries in the public cloud that can scale to support the demanding tasks of distributed computing.
The flexibility and scalability of the public cloud eliminates the need for a business to make massive to accommodate short-term peaks in demand investments. Supplies of public cloud computing providers resources, and the company pays only for the resources they consume.Despite its advantages, the hybrid cloud may present technical, commercial and management challenges. Workloads private cloud need to access and interact with providers of public cloud, hybrid cloud therefore requires the compatibility of the API and robust network connectivity.For the cloud hybrid of public cloud connectivity problems possible violations of the SLA and other interruptions in the public cloud service possible. To mitigate these risks, organizations can work loads hybrid architect interacting with various public cloud providers. However, this may complicate the design and testing workload. In some cases, the workload scheduled for the hybrid cloud must be redesigned to meet specific API providers.Management tools such as Egenera PAN Manager cover, RightScale Cloud Management Platform and Enterprise Cloud Management Scalr help companies manage workflow creation, service catalogs, billing and other tasks related to the hybrid cloud.
