background
Video, has now become more and more like the exchange and communication, a variety of on-demand, live platform, after another short video APP, attracted a large number of user groups, and for the video industry, storage and distribution are the core needs to be considered section. How to ensure the reliability and security of the video storage, video distribution speed and stability, a video industry is every user need to consider.
significance
If you use the server completely from the line set up video services, users need to bear the high cost of bandwidth, and the result is not satisfactory; Ali cloud video-on-demand audio and video is a capture, edit, upload, automated transcoding, media asset management, efficient cloud clip processing, distribution accelerated video playback in one-stop audio and video-on-demand solution that combines the reliability of OSS objects stored in the data storage and cloud Ali CDN node powerful distribution capabilities, to provide a full end-to-video link service, users do not need to consider storage and bandwidth bottlenecks, on-demand, pay by volume. For some start-ups, as well as some early projects, it is a very good way to control costs. Then this article will discuss how to effectively save costs in the process of using a video-on-demand in the cloud Ali.
Billing and analysis
First of all, we want to know Ali cloud video-on-demand billing and accounting items. Billing method according to the amount paid mainly to be used in an amount according to the actual deductions; charging divided into four major parts, namely the storage, the flow rate, transcoding, auditing. So what is the cost we have to bear, and what the cost could be avoided it? We are speaking about.
storage:
According to media files take up much storage space to billing. One should note that the item is stored is called a memory outflow rate billing, below
Many students do not understand how the traffic is generated out of storage, and in our video-on-demand packages package purchase page also pointed out that packages package could offset the outgoing traffic flow does not contain storage
In fact, before the use of video-on-demand, is the need to accelerate the console to configure domain name
Because we VOD itself uses OSS for storage, if we do not add a domain name, then uploaded onto video access will default address is the address to access the OSS
若使用这个地址访问，就会产生存储流出流量，而这个流量是没有资源包售卖的，而且单价会远远高于点播下行流量，当配置了域名之后，地址就会发生变化，而这个地址就是经过CDN加速之后的地址，速度更快，单价更低，并且可以使用资源包抵扣。温馨提示：点播控制台配置了加速域名之后，还需要到域名解析控制台添加CNAME解析喔。
流量：
包含了按流量计费以及按日峰值带宽计费两种，二者只能选其一，可以在控制台进行切换。那么我们应该如何选择计费模式呢？当我们的业务流量长期处于平稳阶段，不会出现大的波峰波谷的时候，选择按峰值带宽计费，会较划算；而当我们的业务流量会随时间的改变而发生明显变化，有明显的波峰波谷出现的时候，比如中午或者晚上流量非常高，而上午和下午非常低，那么选择按流量计费会更划算，并且，选择按流量计费可以购买资源包进行抵扣，资源包的价格本身会在原价的基础上降低，而遇到活动期间购买还能享受到更多的优惠，计算下来单价会更低。
转码：
分为普通转码和窄带高清转码，窄带高清的单价会比普通转码更高，那么我们应该如何选择呢？窄带高清的作用是什么？相比于普通转码，让视频在相同的清晰度下，能带来更低的码率，更低的码率意味着观看同一个视频消耗的流量会更少，这样就可以帮助我们节约更多的流量成本。普通转码和窄带高清转码都能支持480P、720P、1080P、2K、4K转码；我们可以根据业务的具体需求来使用，转码模板可以自行到控制台进行配置，具体操作可参考https://help.aliyun.com/document_detail/86068.html?spm=a2c4g.11186623.6.570.7b246a58b5Y4Ih
审核：
Smart auditing services, according to when reviewing the video length to charge for open service platform, network monitor now very strict, there are many platforms probably because of an oversight, allowing users to upload a number of illegal video, resulting in service was closed, causing a lot of loss of business. If your platform is user self upload videos, this time consider using our intelligent audit services, to reduce some of the labor costs, prevent abuse occurs, the cost of labor costs and intelligent audit stack up, you need your own the measure.
to sum up
Through the above analysis, we can draw some conclusions:
1, after the opening video on demand service first configure accelerate the domain name, address using the accelerated access, avoid storing outgoing traffic.
2, according to the actual traffic bandwidth usage to select the traffic billing.
3, rational use of transcoding service, although it will increase the cost of transcoding part, but you can save more traffic costs, but traffic is often account for the bulk of the part.
4, can compare the cost of using artificial intelligence review and audit, the more human resources into the business, but this is not simple and tedious work, can improve the operating efficiency of the platform.
5, buy-on-demand packages package to be deducted, it can be the most direct cost savings, more cost-effective to buy Oh during the event.
