What is the difference between lightweight application server and cloud server?

Differences: 1. The lightweight application server is for stand-alone applications, while the cloud server ECS does not impose any restrictions. 2. The scalability of lightweight application servers is poor, while the scalability of cloud server ECS is good. 3. There is basically no network expansion problem for lightweight application servers; cloud server ECS is under a private network VPC, and users can customize the private network.

The operating environment of this tutorial: Windows 10 system, Dell G3 computer.

Lightweight Application Server: A new generation of computing services for stand-alone application scenarios, providing one-click application deployment, one-stop domain name resolution, website publishing, security, operation and maintenance, application management, etc. Serve. It greatly optimizes the experience of building simple applications and lowers the threshold for entry-level users to use cloud computing products.

Lightweight application servers are sold in the form of yearly and monthly packages.

Package resources include:

• Commonly used application images and system images selected by Alibaba Cloud;

• Cloud server computing Resources, including SSD-based storage resources and network resources;

• Basic functions of other Alibaba Cloud products (DNS, VPC, etc.)

Simple Understand that the lightweight application server is similar to the virtual host we used before. It is mainly used to deploy websites. The difference from the virtual host is that the bottom layer of the lightweight application server is a cloud server. The operating system includes a running environment, and you can upload the program and use it.

Cloud Server (Elastic Compute Service, ECS for short): An IaaS (Infrastructure as a Service) level cloud computing service provided by Alibaba Cloud with excellent performance, stability, reliability, and elastic expansion.

It is not difficult to see from the definition that lightweight application servers and cloud server ECS are mainly different in the following aspects:

1. Usage object: lightweight application server For stand-alone applications, cloud server ECS does not impose any restrictions;

2. Scalability: The lightweight application server provides only a few configurations to choose from, and the upgrade limit is large; cloud server ECS provides dozens of types and hundreds of configurations to choose from, and supports upgrades. At the same time, ECS supports use with other applications such as RDS and OSS;

3. Network: The lightweight application server is targeted at a single machine. There is basically no network expansion problem; cloud server ECS is under a private network VPC, and users can customize the private network and interconnect with offline IDC or other cloud products through the network;

Extended information:

Features of lightweight application server:

• Quick start: start your application with one click in 30 seconds

• One-stop experience: single-interface integration of domain name resolution, website publishing, server management and other operations, one-stop functional experience

• Selected images: Alibaba Cloud’s independent research and development and precision Choose the dual choice of market images to provide you with a high-quality image experience

• Rich applications: continue to provide a variety of application functions to help you conveniently manage, configure, and analyze applications

Cloud server ECS features:

• Stable: instance availability reaches 99.95%, cloud disk adopts 99.9999999% reliability design, automatic downtime migration, automatic snapshot backup, data Recovery is more convenient

• Flexibility: Supports the creation of 1,000 instances at the minute level. Multiple flexible payment options are more suitable for the current business situation, while bringing flexible expansion capabilities. Both instances and bandwidth can be used at any time. Upgrade and downgrade, the cloud disk can be expanded

• High security: Provide free DDoS protection, Trojan killing, anti-violent cracking and other services. It has passed multi-party international security certification, and the ECS cloud disk supports data encryption function

• High performance: A single instance can have up to 88vCPU, 704GB memory, single instance performance can reach up to 7 million PPS network sending and receiving packets, 35Gbps bandwidth

• Ease of use: Rich operating systems and application software can be easily deployed with one click through mirroring. The same mirror can quickly replicate the environment in multiple ECSs and easily expand

• Expandable Performance: ECS can be seamlessly connected with Alibaba Cloud's various cloud products, and can continuously provide complete computing, storage, security and other solutions for business development
