 Dear students, in this module, I'll be continuing what we started in the previous module. It's a continuation of how to select your ISP, what features you need, what you are looking and what you should be looking for in a database service provider and all the associated things with it. One important aspect with reference to domain name is managing your domain. Now, I have stressed domain registration, domain names a lot of times because it is very important. As I've shown in previous slides, a domain name can be selling for tens of hundreds of millions US dollars. There's a huge amount of money. And as, so the keyword is very important. And as in the property business, the saying goes that it is the location. It is the location. The third is also the location. So it is a domain name. Everything is a domain name. I'll talk more about it. So when you are deciding about your internet service provider, when you are deciding about your database service provider, these are the some of the things which you should be looking at. That which services do you need? It depends upon what you already have. And how do you get started? Could it be a dedicated connection? Could it be a switch connection and so on. And how to select an ISP? What you should be looking for should be the bandwidth, should be the pricing, should be the support. What else? And the issues of domain ownership, which I'll go into more detail. Finally, how to connect your server to the internet? What options do you have? Let's go ahead. So these are the services which you should be needing. And maybe you have most of those services, if not all of them, depending upon what you're doing. So you have those internet telephony also, which has been around for a while and instant messaging, which takes very short time to exchange messages. Telnet connection. And you may also need FTP connection file transfer protocol depends upon what type of solution you have opted for and how much money you have paid for and so on. So I will not go into more details because everybody or most of the people knows about those things. So how do you get started? Which services you already have? Now, if you have a website, it means that you have a mechanism to connect to that website. And you have a mechanism of uploading the files to that website and removing the files from that website also. Right. And if you have a domain name or a server site, okay, then of course you can also have the specific domain specific email address. You at my excellent domain dot com. Okay, you have that email address depend if you have your domain name also. And of course, what type of facility you have to upload the files when you have your own domain name and so on. What type do we have a shell environment or a limited and whatever. And do you have database hosting? So you can have a domain name and you can have all these facilities, but you may not have database hosting. If you have and you must be developing web based database applications, so you must have database hosting facility. If you don't have it, it means you need database hosting. Of course, there are different packages. Of course, there are different facilities and different pricing. I will talk about them and we'll go through them over them. So how do you choose an ISP? Look for the ISPs, which are and who are operating in your area. There may be national ISPs, there may be regional ISPs, ISP is an internet service provider. And you should be talking to the ISP which operates in your area. Or you should be talking to the ISP, which is a national ISP and is offering the plans and the pricing in your area, which they have advertised because it may so happen. Is that the plans and the pricing which has been offered may not be available in your area, may not be offered in your area. So don't assume anything. Check. Find your bandwidth needs. How much traffic you will be looking at over the period of time. Okay. Because high bandwidth needs if you if you pay a lot of money for the high bandwidth and you will not be needing it to why pay the extra money. Test your bandwidth. See how much traffic is going across your website. And finally, then select your ISP. So remember that if you make the right choice, if you make the right connection, if you make the right contract, then you can go ahead for a long time with your ISP instead of some ugly breakup and you are left with your files and data and high and dry. It's very, it can be tragic issues of domain ownership issues of changing the host. Now, if you don't own a domain, try to understand these things. The details are in the in the in the notes. If you don't own a domain, you may be hosted on a website or a company, this is a company.com slash customer slash your company. Okay. Now, if that company closes or you move to another company, your address may change the second company.com slash tilde. Okay. Some customer slash your name. No, what's going to happen that the people who have your address earlier, if they type that address, they will not lead to anywhere. That is the big problem. That is the issue of that off having not having the domain name. You need to have your own domain name. So this makes that hosting transparent to the visit visitors. What will happen is that if you you have your domain name, if you change your ISP internet service provider or the web database service provider where you're hosting a website, only one entry needs to be made in the center registry or with the ISP only one entry. That's it. You are in business. Come at least one domain contact. Now, when you register the domain, there are two contacts billing contact technical contact. You must be one of those contacts. Otherwise, you cannot make changes in your domain. You cannot transfer your domain. Okay. And because these contacts authorize. Right. When you register a domain, the company selling the domain will automatically make themselves the billing and the technical contact check with them. Okay. Because then if you are not there, it's very difficult to shift your domain from company A to company B. You should be careful about those things. This domain is very expensive. It is a very high value. All your effort has gone into it. It can be costing a bundle. Okay. And finally, how do you connect your website? Okay. You use a static IP static IP means that an address is given to your to your application running on a server and that is a fixed address. You can attach devices at that address. You can attach a camera on the static IP address because that is fixed. Okay. Or you can have a permanent connection. Permanent connection. Your server is permanently connected to the Internet over Lee's line over ISDN over frame relay. Of course, the cost varies or you have your server physically moved to the ISP. It sits there. It is taken care over there. Okay. And finally is your database hosting database hosting on your ISP on the same machine or different machine that we've already discussed in the previous module. So that's all I have to say and discuss in this module. Thank you for your time.
