First, the difference between them, please see their definitions below.
SaaS rental:
Rent means that you can pay rent on a monthly, semi-annual or annual basis. At present, the exam cloud official website can be automatically selected according to your time demand and the number of concurrent students. When the exam is due, there will be SMS notification in the exam cloud. You can choose to renew the fee or not to use it. As long as your data does not exceed the storage space allocated to you, all your previous data will be saved for you.
Privatization acquisition deployment:
You can buy out the exam cloud online training exam system at one time and deploy it on your own server. So you can buy it once and use it forever, and all the data will be saved on your own server.
Mixed deployment:
Because SaaS rental version is very popular, everything is a template, and everyone has the same function. But sometimes our enterprise will have its own special needs, and it may not be used often, so this mixed deployment can be used at this time. You can only connect the exam cloud service on your server for more than 1 month; Or directly connect the test cloud to your existing WeChat official account or nail it; Or open an independent account to help you privatize and customize some special cloud services.
Second, how to choose
According to your usage frequency and customization requirements.
Use less, the universal version is suitable for you; Choose SaaS version, because it is relatively cheap at this time;
Use less, there are several special requirements; Choose mixed deployment, because it is more economical than the deployment version at this time;
Often used, there are a lot of customization needs. Suggest privatization, buyout deployment, because he is looking at a one-time payment, and it is the most cost-effective in common use.
Depending on your data storage space
There is a lot of information. It is recommended to privatize and buy out the deployment, because he will help you match the appropriate server according to your needs. The memory donated by the cloud version is fixed, and there is an extra charge for increasing the memory.
In other cases, the SaaS version is enough.
Concurrency situation
If your company has more than 2K employees and there are many branches, it is recommended to privatize and buy out the deployment. Because he will match you with an independent server according to these, in this case, you basically have no worries in the use process.
When letting SaaS rent the current exam cloud, it is not limited to concurrency, but if it is bought out, it will be more expensive if it takes a long time to use. Because SaaS usually rents his server, but for such a high concurrent customer, Exam Cloud usually opens a separate server for him, so if it is used for a long time, the cost will be much higher. If it is only occasionally, it is more cost-effective to rent SaaS.
Other supplements
If your company already has some basic OA systems, but only wants to join the online training exam and doesn't want to spend too much money, mixed deployment is the most suitable, because it can customize data docking for you, and the cost is more affordable than privatization buyout deployment.
In short, the most important choice is the frequency of use and customization requirements.
