Information about Email,POP3 and SMTP server.

Saturday, August 16th, 2008

Hello,

If you are related with the internet industry or a regular user of the internet then you must be aware about the word email.Email is the service on the internet which enables you to send messages to a person on his or her email address.For this you also should have an email address.You can make an email address for your self free of cost.If you receive an email from someone then you get you email from a server.This server is none other than the POP3 server.POP ( Post Office Protocol ) is used to describe how email clients interact with mail servers.POP is the mail server which is used for the incoming mails or in other words POP is the server which gives you a service similar to the letter post service.Only the difference is,this particular service is for your email and your incoming mails are posted on your email address.So when the users connect to their ISP POP servers,the servers get connected to the their email software and then all the messages are downloaded.But make sure that POP servers only receive messages,they do not send them.

The server which is used to send the mail messages is called the SMTP server.SMTP stands for Simple Mail Transfer Protocol.A Protocol stands for sending mail messages between servers.When an email is sent by a client,it is first sent to a SMTP server.SMTP server then receives the email across the internet.After the email has been received it is then sent to the intended recipients through different routes so that he can receive the email with the help of the POP server as mentioned above.When an email is sent to a recipient,it also requires few other servers apart from the SMTP server so that it is sent to the desired email address.

What is RAID ? Mirroring Solutions (RAID I)

Saturday, August 16th, 2008

Hello,

As in the computer and in the internet industry one of the most important thing is considered to be the Data.Companies have been working since a very long time to introduce new technologies and techniques to make sure that the Data which is very important is safe and accessible all the time.They have been successful in finding the new technologies and are still working to find newer and better technology than the previous one.They have found out a way to save the data which is very important for you.RAID (Redundant Array of Inexpensive Disks) which is one of the latest and a very good option for you to save your important data.RAID actually involves two or more physical hard disks into a single group which can be done by using special kind of software and hardware.This can be considered to a better option as compared to a single hard disk as it also offers an excellent read speed and write-speed.Software solutions are implemented in operating systems in such a way that they would present the RAID drive as it  a single drive to applications in return.Whereas the Hardware Solutions continuously work on presenting that they are attached to the system as a single hard drive and this is the reason why the operating system is unaware of the technical workings.Also for the Data which is very important and require very high reliability there is RAID I.One of the techniques for the Data redundancy used in RAID I is called Mirroring.

Raid1 What is RAID ? Mirroring Solutions (RAID I)

Mirroring is the technique in which the data is written in two copies,this means that all the Data in the system is written on two drives instead of one.This is done because,if one of the drives mirrored fails or does not respond due to some mechanical or other reasons than it can switch to the other drive so that it can work and provide the user with uninterreupted accessibility.This technique is also called fault tolerence.This is done so that there is no loss in user accessibility.The main purpose behind using this techinique is to provide the user with 100% data redundancy so that the Data is fully protected and is available all the time as if one of the drive fails then the other can help to provide the data.For this process,the Mirroring drives constantly require a number of drives as well as high technical skills.So the main reason for using the technique Mirroring is nothing but to provide 100% accessibility so that the Data is available all the time for the user and this is possible with Mirroring as if one of the drives fail then the other drive can be used to accesss the Data as the data is also available on it.However while buying RAID make sure that you buy twice the capacity if the data is very important and requires extremely high performance accessibility.

What is Reseller Web Hosting ? Advantages and Disadvantages

Saturday, August 16th, 2008

Hello,

Web hosting involves many products or in other words types of web hosting for different customers.But what if you want to become a web hosting provider or you want to change your plan  if you are already a web hosting provider.If this is the case with you then reseller web hosting is what you are looking for.Reseller as the word suggests,is a kind of web hosting type where you can be a seller and sell different kind of web hosting plans and that too with the amount of money you wish for each plan.A reseller account is good to start with,if you want your own web hosting service and want to provide people the service.It is also very good if you are a small scale web hosting reseller already.

Reseller web hosting allows you to provide the web hosting to other people and also if you have a reseller account you can use it entirely if you want to.It means you can host multiple websites under one web hosting account and even share the account with someone if you think that the resources are more than enough for you.So,it is also a kind of shared hosting account.The other advantage could be taken as the cost of the reseller account.As it is a kind of shared hosting account it costs comparatively less than the VPS and the Dedicated servers and the best part is you will have the many kind of features as the VPS and the dedicated servers with a less cost.So it can be considered as a cheaper alternative to VPS and dedicated server and as you can host multiple websites under the same account it can be considered as a very good option if you want to upgrade from a shared hosting account to a account which is as beneficial as the VPS and Dedicated servers but at an affordable.If you are providing  a web hosting service to customers then make sure that your customers will never know that you are reselling the web hosting service which is yet another benefit to you.Also the support given with a reseller account is more openly given than the VPS or Dedicated server account.

After all these features you might think that Reseller web hosting does not have any disadvantages but amke sure it has.If you have a reseller account,then hosting multiple web sites might be problematic to you as your web hosting provider will not be good to you as your account is on the shared server on which he might have other customers who are not satisfied with the time taken by their website or websites to download.As it is a kind of shared hosting account you are on hosted on the shared server and as you are sharing the account it is possible that you will face the same kind of problems that are faced by a client who has an account on the shared server.Also,If you will upgrde from a shared hosting account to a reseller hosting account you might not notice any kind of increase in performance or reliability.It is said that you can sell the account to your own customers at a price you wish but,your web hosting provider will not allow overselling,that is selling the plans to the customers with the amount which is not appropriate and this can also be a disadvantage to you.

Saturday, August 16th, 2008

Hello,

Many people are aware of the different types of web hosting available in the market.We select the web hosting type and package according to our needs and the main point is we want our web site to be hosted by a web hosting provider who is reliable and offers good quality web hosting at an affordable cost.For the people who earn money only through their websites,it is really very important that their website is always uptime so that their business do not get affected.This is a very serious topic for the people who earn money only their website and the fact that it is not sure whether your website will remain uptime or not even if you have a dedicated server hosting your website cannot be unnoticed.For this the only thing you can do is look for a better option and if you are looking for a better option than a dedicated server to keep your website up all the time than clustered web hosting is for you.

Clustered web hosting is a type of web hosting service where you will have multiple servers or in other words a group of servers hosting your website.As there are multiple servers even if one of the server fails or is not working due to some problems then the other servers can help you out to keep your website uptime as your website is backed with other servers other then the main one.If you have have your website as the only source of income than clustered web site hosting will be very beneficial to it as it has the reliability you need as you only have your website as the source of income.Clustered website hosting is for the businesses and websites that are resource intensive but require uptime so that they have their websites working all the time.If the websites are mission critical then too, clustered website hosting is very necessary.

Clustered website hosting involves many advantages for the people who need maximum website for their website and also want to cover the other aspects like the domain and also services such as DNS and email which is very important for any business to continue and flourish.If any server in the cluster fails then too these services will work as the work is then distributed among alll the other servers in the cluster.It is also very important for the business sites who are only dependent on their website for the source of income.Any other hosting type will not be able to give you this kind of reliability as in almost all of them,one server is used to host the all services of a single website.

After reading the above lines many of you might think that clustered web hosting involves advantages only,but make sure it also has some of the disadvantages.Clustered web site hosting is good for you if you have a website which is giving a good amount of income because if it doesn’t than clustered website hosting is very expensive for you to even think of.As it has a number of servers in the cluster,the cost and the maintainance of the servers is to high.Also,you have to find a web hosting company which is trustworthy as you might be given the resources which will not use even once and you will not be able to use them even if you need them as the resources will not be truly available.In one word this is called as overselling in the web hosting industry as you will pay for the service which is not given to you.

What is a Teamspeak server ?

Thursday, August 14th, 2008

Hello,

Web hosting involves many types of hosting.These hosting types are according to the clients requirements.Apart from shared hosting,VPS hosting and dedicated server hosting there are a few types of hosting services available.One of them is the Teamspeak server hosting service.Teamspeak is a Voiceover IP software which is similar to the call conferencing on the telephone which allows a number of users to speak or say chat with other users using or chatting on the same chat channel.Teamspeak client software is used by the users to connect to the Teamspeak server they want to use,from there they can select the chat channels and join them.The Teamspeak is generally used by gamers who play multiplayer games and is very good for them as they can speak to or chat with their teammates or opponents very easily with their hands on the controls as they can use headphones to chat with each other.This increases the competition and creates more excitement among the players which is very important while playing a game.

The Teamspeak server runs as a dedicated server which is entirely seperate from the clients.Currently the teamspeak servers support Linux and Microsoft windows.To control server administration and to perform the settings a web based or telnet interface is used.TeamSpeak 2 server even supports virtual server instancing. This means that with only a single process you will be able to run an infinite number of servers on your server by allowing Teamspeak  to create a new process virtually.There are two types of accounts  Server Admins and Super Server Admins.These accounts can be given access to the administrative interface when logging into the administative interface.Server admins are only limited to the virtual server related to their account whereas the Super Server Admins have full access to all virtual Teamspeak servers hosted on that server where more than one server instance can run on one single physical server.

Physical conditions required for a data center.

Thursday, August 14th, 2008

Hello,

If you talk about web hosting then the first or say the most important is the data center where the servers are kept to host a website.As the servers have all the data,it is very necessary that the servers are very well secured.For this purpose it is very necessary that the data center is well designed and well planned.This means that the data center should be able to face any threat which could occur.For that a data center should be secure,defendable and cost effective.It is very important to consider the threats which you think are rediculous and are not worth considering but even those threats should be written and one should work on them to make a data center.Even the dangers which are not expected should be considered and on should work on them so that they can be prevented.Thne the data center can be made with multiple layes of security and can be protected against the worst threats.For all this it is also necessary is to make a note of the cost.The main thing to remember while making a data center is to plan for the worst possible threats and to work to make the data center well protected against them and hope for the best to happen.

The first part is the site selection for the data center.A site where you get a mixture of all the features is the ideal place for the data center to be constructed.An area where the possibility of natural calamities like earthquakes,landslides,floods etc are minimum should be selected.The earthquakes are possible any where in the world but by selecting a suitable place and by hardening the structure it is possible to make the data center resist able against the calamity.For that purpose important measures should be taken so that the land of the site should be soil stable so that you can protect the data canter against the natural calamities.It is also important to check the past of the site so that you get an idea about the nature of the soil,the stability and the ground contamination on the land by previous owners. The drainage facility of the data center should also be up to the mark so as to avoid the accumulation of water at the time of heavy rains or floods and also the melting of ice at the time of snowfall and the soil of the ground should be checked so as to know the ability of it to absorb water so that in cases of heavy rains or water accumulations the soil absorbs the water quickly.

The area where the data center is to be build should not be a flood plane and it will be a very good option to have it on a height so that there is no problem at the time of heavy rains and floods.The secure data center should be constructed at a quiet place away from the places which experience high traffic but at the same time it should have multiple roads connecting to it for the time of emergency.It should be at a place which is away from army area,sports areas and the factories which generate noise or chemical pollution which will affect the data center.It should be at a place which has stable climatic and weather conditions as variations in these conditions will affect the data centers atmosphere.The data center should be away from areas experiencing frequent criminal or political activities as to save it from riots,robbery and other activities which will create problems for the data center.

Apart from all these terrestrial problems you should also consider the airborne problems as it is very dangerous to have an airport near the data center.The airport has take off and landings and these are not at all guaranteed to be the successful ones which could make an aircraft to crash anywhere nearby an airport and if the data center is near to the airport then definitely it is very dangerous to have one.also when a aircraft is taking off or landing it is easily possible that an aircraft looses its parts which can fall of anywhere resulting into losses.You should talk to the neighbors of the place who might be able to give you the information of the constructions which might start in the future which can definitely help you to plan about the construction of your data center to make it safer and also in the best possible way.

A good site location is really very important as the work in the data centers is largely done on the power grids and also the generators which are very important so that the power supply is non stop.Apart from all this you also have to pay attention that the police and the fire brigade is nearby for help at any time.Hope so that you do not need that but you never know.For a secure data center you should take precautions.You should also see to it that the medical facilities and the food facilities like a restaurant or a motel is nearby so that you do not waste much of your time in travelling and you keep your staff happy after all they are also important.

The building of your data center should be made of of excellent quality to be able to resist the natural calamities as well as problems caused due to the human beings.It should be able to resist winds of the speed of 200 miles per hour and also the rains and snowfall.these building should also be able to withstand the storms which are tremendously destructive and should be also fire resistant.The building should be constructed in the middle of your site so that all four sides of your sites can be seen easily by which the problems coming towards can be seen by which it might be possible to save the data center.For the security of the data center it will be better to give it a name which does not exist so that the data center is well protected.also,the data center should have a look at the activities of the company’s nearby so that there is no plans going on so that the data center will be in danger.the data centers  building should be build with a veery hard material like concreate so that it can withstand the rains,snowfalls,storms and different other natural calamities.also ,the temperature inside the data center should be stable so that the machines are able to run all the time.For that the data center should have windows so that the temperature inside the data center is maintained as the hot air can pass out and the cold air can come in the data center.But the windows should also have some precautionary measures so that the contaminated air does not enter the data center and affect the machinery if the data canter.The data center shold be made atleast 20 feet high ceiling to save the data center from over temperature conditions. The roof of the data center should be made of a very good material even if the material is costly as it is important to have a strong roof to save the data centeer from natural calamities.

Overselling website hosting:-Disadvantages

Wednesday, August 13th, 2008

Hello,

As every web hosting package has some disadvantages oversold web hosting also has some disadvantages.As for some it might appear that oversold website hosting has only advantages but for many it is proved to be a disadvantage as compared to other forms of web hosting.One of the reasons is that people consider is the fact that it is important for any webhosting account that it has unlimited resources,since unlimited server resources don’t even exist.So if you are hosting your website by an oversold web hosting account you should switch to a standard shared hosting account so that you get better value for money as you cannot deny the fact that standard shared hosting provides you with better support and reliability than oversold web hosting.One of the main or you can even say that the worst disanvantage of oversold web hosting is the reliability.Oversold web hosting are not reliable because there are many users having an account and using the same server and that is the reason why the servers get overloaded and results in a crash which is regular when it comes to servers of oversold web hosting.So due to these reasons if you are running a critical or in other words a very important website than it is recommended that you choose or stick to standard web hosting.
