UniCloud is a server developed by DCloud with JS and free of operation and maintenance

UniCloud is launched by Ali Cloud and Tencent Cloud. It is a cross-terminal cloud product developed with JS on the server side based on Serverless.

1. No operation and maintenance, more worry

2. Low server cost

3. Easy to get started and quick to get started

4. Development efficiency, double improvement what is cloud server?

A cloud server is a basic computing component consisting of CPU, memory, operating system, and cloud hard disk. After the cloud server is created, you can use the cloud server on the cloud just like using your own local PC or physical server. (if it is not contact with friends, can be understood as a cloud server is a virtual computer) the opening of the cloud server is buffet, you only need to specify the CPU, memory, operating system, specifications, can login authentication way, at the same time can also adjust the cloud server specifications according to your demand, for you to build an efficient, reliable and secure computing environment.

Using a traditional cloud server requires us to choose hardware and bandwidth configurations, because the higher the configuration, the better the performance of the server.

If the configuration does not meet the requirements, once the peak traffic comes, the server will crash and other failures, so we have to rely on the peak performance standards,

Pay attention to the high configuration of the server to prevent the occurrence of this situation, the situation of low traffic, the performance of the server is not high, so those high configuration are idle and wasted

Unicloud is an advanced sharing business model. Its cloud is a huge serverless resource pool with countless Node processes. When a user makes a request,

Serverless will allocate idle resources to run the developer’s corresponding cloud functions. Your code runs directly on the cloud functions, no hardware configuration, operating system,

The concept of web server is like water and electricity, there is no complex threshold, pay-as-you-go, traditional server system environment requires developers to build and upgrade their own maintenance,

You don’t have an engineer who manages the server, and whenever the user is attacked, you might have to wake the engineer up in the middle of the night to do maintenance, and that’s quite Alexander, and that’s a lot of work,

However, developers just need a place to run to the server and endure so much triviality that they shouldn’t.

UniCloud and Ali cloud and other traditional cloud difference and relationship?

1. UniCloud is packaged by DCloud on the Serverless service of Alibaba Cloud and Tencent Cloud.

It consists of laaS layer (hardware and network provided by Ali Cloud and Tencent Cloud) and PaaS layer (development environment provided by DCloud).

Developers are free to choose suppliers for uniCloud’s hardware and network resources, switching back and forth between Alibaba cloud and Tencent Cloud.

2. Although account opening and payment are made through DCloud channel, in fact, developers automatically set up accounts and top up balances with cloud manufacturers, and DCloud only receives commission from cloud service manufacturers.

3. Although DCloud tool is used in development, when the application goes online, the serverless of Ali Cloud or Tencent Cloud directly connected to the mobile terminal will not go through DCloud server.

In the past, many front-end engineers wanted to make a full stack, and they needed to learn a back-end language such as Java, PHP, Python, etc. You also needed to learn database design and query syntax, learn Linux, to master server security and operation and maintenance.

With uniCloud, you only need to know JS, just need to write business code, and use JS as a language to solve the front-end and back-end development

A service space corresponds to a set of independent cloud development resources, that is, each cloud development resource does not affect each other, but a cloud space is used by multiple applications.

For example, a ride-hailing car is connected to the same ride-hailing car,

These are lists of cloud functions that are uploaded to the cloud service. Cloud functions are node.js code, which is the business logic that runs on the server side,

We upload it to the cloud space, and it can be called by the front-end code,

UniCloud cloud database and mysql and MongoDB differences

UniCloud cloud database is an enhanced version of MongoDB with improved ease of use and is richer, more flexible and front-end friendly than mysql. Details: uniapp.dcloud.net.cn/uniCloud/fa…
