Recently, my customer's requirement to build a database on ali cloud, convenient customer visit in the United States, don't know how to set up the server, troublesome everybody a great god help, thank you very much,

CodePudding user response:

Using a Delphi 6.0? Don't know why you use such a low version, but I don't suggest you directly open ali cloud virtual machine on port 1433 to access database,
Suggest you to make application of three layers, using Midas access layer, efficiency will be higher,

CodePudding user response:

Ali cloud database, can only be accessed directly, it does not support DataSnap three layers,
DataSnap three layers, it is necessary to set up the server, through the server to access the database,

CodePudding user response:

Redevelopment workload is too heavy

CodePudding user response:

Lyhoo163 hello, direct access to what you need to do

CodePudding user response:

Baidu ali cloud VPS, buy the server, is a fixed IP virtual host, built the database in the virtual host, fill in LAN LAN IP, with the fixed IP with respect to ok

CodePudding user response:

Another way is better, it is through the VPN line, connection, as long as there is network, global connections and general,

CodePudding user response:

The best client server database into three layers structure it would have been better

CodePudding user response:

refer to 7th floor xiaocongzhi response:

best into three layers structure will have better client server database that

this way, not on the cloud, can only use (rent) server,

CodePudding user response:

Can consider to switch to WEB mode, so you need not test port problem!

CodePudding user response:

Old system routines, is not this limit which is limit, VPN mode for foreign customers visit to be a better solution, it is need not add extra workload, 2 it is safe, 3 it is stability, anyway, than on a lot of good words, ali cloud who used who knows, the only requirement is that you should have an Internet cable for my speed is pretty good, suggested that more than 20 m broadband telecommunications optical fiber,

CodePudding user response:

The VPN can use teamview structures (recommendation, fast, stable, more connection times will be system considered commercial use, to pay,,,), the second is the dandelion VPN (speed, is the number of the free version has three client restrictions).

CodePudding user response:

Rent a virtual machine, install the database, use the IP and port number, user name, password link, IP is a public IP, clients connect directly to estimate possible, only the database directly exposed to the public this kind of situation is rare, no one do it

CodePudding user response:

Put on ali cloud database, there are two ways can rent ECS is cloud server, and then in the database is mounted, daily operations will be on your own, or just rent RDS is a database server, ops is worry, choose according to own situation,
