The pure SSD architecture ECS is an elastic and scalable cloud computing infrastructure service, including CPU, memory, disk, operating system, network and other computer infrastructure components. It can flexibly expand the amount of resources, save computing costs and simplify IT operation and maintenance.

• example : refers to the virtual computing environment. It includes CPU, memory, hard disk, system, network and other basic computer components.
• image ： It refers to the template of the instance running environment, generally including the operating system and pre installed software. The operating system supports multiple Linux distributions and different Windows versions.
• Network type
  Dynamic BGP multi wire network: Establish EBGP neighbors with multiple operators at the same time, and receive the whole network routing table of all neighbors in real time, and obtain the optimal path according to the algorithm of BGP protocol. At the same time, the links of multiple operators are disaster recovery for each other. When one of them fails, the route will be automatically switched to ensure smooth network connection.
  Static BGP multi wire network: Establish EBGP neighbors with multiple operators at the same time, and receive the routing table of some neighbors in real time, and obtain the optimal path according to the algorithm of BGP protocol. At the same time, the links of multiple operators are disaster recovery for each other. When one of them fails, it is necessary to manually switch some routes to ensure smooth network connection.
• IP address ： This includes the private IP for intranet communication and the public IP for Internet access.
• Data center region ： It refers to the physical location of the resource.

Highly available network

With dynamic BGP network, its availability is up to 99.95%. Data centers are distributed in five major regions of the country, covering a wide range. Dynamic BGP automatically optimizes the network structure at the first time according to the set routing protocol to keep the network used by customers stable and efficient.

Dynamic BGP has the following characteristics:

• Intelligent routing: The server only needs to set one IP address. The best access route is determined by the core router according to the number of route hops and other technical indicators. It does not occupy any system resources of the server. The server can choose the optimal path for both the upstream route and the downstream route.
• Link redundancy: Because the BGP protocol has the characteristics of redundant backup and ring elimination, when the cloud service provider has multiple BGP interconnection lines, it can realize mutual backup of routes. When one line fails, the route will automatically switch to other lines.
• Unlimited expansion: Using BGP protocol can also make the network have strong scalability. It can interconnect the network with other operators, easily realize single IP and multiple lines, and enable users of all interconnected operators to access quickly.

Application scenarios

ECS is widely used. It can be used alone as a simple Web server, or it can be used together with other cloud products to provide a powerful multimedia solution. The following is a typical application scenario of ECS.

Enterprise official website, simple Web application and development environment

At the initial stage of the website, the number of visits is small, and only a low configuration ECS is needed to run applications, databases, and store files. With the development of the website, you can improve the configuration of ECS and increase the number of ECS at any time, without worrying about the shortage of resources caused by the sudden increase of business with low configuration servers.

For example: Build small websites, personal blogs, forum communities, personal learning environments and rapid development environments

Multimedia, high traffic apps or websites

Multiple cloud servers are used together. Static pictures, videos, and download packages are stored on different servers to improve user access experience. At the same time, with load balancing, user access waiting time can be significantly reduced, server load can be reduced, and high performance can be achieved.

For example: Build e-commerce websites, video sites, medium and large communities, government systems and enterprise ERP systems

data base

Supports databases with high I/O requirements. The ECS with higher configuration and SSD disks can support high I/O concurrency and higher data reliability. Multiple servers with slightly lower configuration can also be used to configure master-slave read/write separation load balancing to achieve a high availability architecture.

Apps or websites with fluctuating traffic

For some applications, such as 12306 website, the traffic may fluctuate greatly in a short time. By using elastic scaling, we can increase ECS instances when the business grows, and reduce instances when the business drops, so as to meet the resource requirements when the traffic reaches the peak, and reduce the cost. If load balancing is used, a high availability architecture can be achieved.

ECS usage

Web operation interface for server management is provided to facilitate user management of ECS. The user can log in to the console ->server management interface to operate and manage the corresponding instance. Server Management Page

Console operation overview

• Remote connection: Use the remote connection function of the ECS management console to enter the instance login interface.
• PUSH server: Transfer the idle server to another user.
• Resource monitoring: Enter the corresponding server management interface to monitor ECS CPU usage, memory usage, network traffic and other information
• Resource alarm: Set alarm rules and add contacts. If the rules are triggered, the system will automatically alarm.
• Destroy ECS: Destroy the server by yourself to prevent the idle server from being used maliciously.
• Reinstall the system: Replace the server operating system.
• Server stop and start: One click to stop and start the server.
• Server restart: One click to restart the server.
• Reset password: Reset the server password.
• Upgrade renewal: Upgrade the server configuration, such as CPU and memory. You can renew servers that are about to expire or expire within 48 hours.
