Virtual host
What is a virtual host
Shared cloud virtual host: virtual host is to divide a server into multiple space of a certain size through related technology, each space is given separate FTP permission and Web access permission, multiple users common average use of the hardware resources of this server. Virtual hosts on the market are shared virtual machine model.
Exclusive cloud virtual host: Compared with Shared cloud hosting, exclusive resources, are the main differences of the whole hardware and software of the server resources, i.e. each light cloud server CPU, hard disk, memory, bandwidth are exclusive, and unlimited traffic, independent IP, pre-installed web applications and database environment, has the advantage of the virtual machine and the server at the same time, And provide visual operation of the control panel environment, simple operation, namely buy and use.
Suitable for the user
Shared cloud virtual host: resource sharing, large space, fixed flow, economic benefits, meet the basic site.
Exclusive cloud virtual host: exclusive resources, large space, unlimited flow, higher configuration, preferred for enterprise site construction.
advantage
Preinstalled the common station running environment and database, do not need users to install. Provide visual host control panel, each function can be completed by clicking the mouse operation does not need users to participate in server operation and maintenance, the product is responsible for the overall maintenance, save trouble and worry.
disadvantage
If you do not have the permission to log in to the server, you cannot customize the server or the operating environment.
It can only be used to build a station, not for other purposes.
Lightweight application server
What is a lightweight application server
Lightweight application servers are next-generation computing services for single-server applications. They provide one-click deployment of boutique applications and support one-stop services such as domain name, website, security, operation and maintenance, and application management, greatly optimizing the experience of building simple applications and lowering the threshold for entry-level users to use cloud computing products.
Suits the crowd
Entry-level cloud computing users who are not familiar with cloud computing but understand the usage of traditional web space, virtual machines and VPS
Individual project developers who need a collection of resources to get into development quickly
Need to create personal applications (such as personal blog, personal cloud disk, etc.) technology amateurs, students
Small and medium enterprise users who need to build a website environment with low requirements and low availability
advantage
Simple and easy to use one-click startup application + server one-stop management application, operation and maintenance, various integrated products with rich applications
High performance: the whole product line uses SSD storage with excellent performance; With ECS shared instances, the performance is sufficient and the price is low: the price is lower than the package price for multiple products
disadvantage
Users are required to have specific knowledge of server management and o&M.
ECS cloud server
What is an ECS cloud server
Cloud server Elastic Compute Service (ECS) is a basic cloud computing Service provided by Ali Cloud. Using cloud server ECS is as convenient and efficient as using water, electricity, gas and other resources. You do not need to purchase hardware devices in advance. Instead, you can create as many cloud server instances as required, and expand disk capacity and bandwidth of cloud servers as services expand. If the cloud server is no longer needed, it can easily release resources and save costs.
Cloud server ECS instance is a virtual computing environment, including the CPU, memory, operating system, disk, bandwidth and other basic server components. It is an operation entity provided by ECS for each user. An instance is equivalent to a VM. You have administrator rights to create an instance and can log in to use and manage the instance at any time. You can perform basic operations on instances, such as mounting disks, creating snapshots, creating mirrors, and deploying environments.
Suits the crowd
IT startups/Internet companies with strong technical capabilities
Traditional industry enterprises with large resource requirements for servers
PaaS and SaaS developers and enterprises
advantage
Cloud server ECS has advantages that traditional servers and virtual hosts cannot match:
Stability: Service availability up to 99.95%, data reliability up to 99.9999999%. Supports downtime migration, data snapshot backup and rollback, and system performance alarm.
Dr Backup: Multiple copies of data are created for each copy. If one copy is damaged, it can be quickly recovered in a short time.
Security: Supports the configuration of security group rules, anti-ddos system, multi-user isolation, and anti-password cracking.
Multi-line access: An optimal routing algorithm based on Border Gateway Protocol (BGP). BGP multi-line equipment room, smooth and balanced national access. Backbone machine room, large egress bandwidth, exclusive bandwidth.
Flexible capacity expansion: 100 ECS instances can be started or released within 10 minutes. Support online non-stop upgrade bandwidth; Upgrade CPU and memory within 5 minutes. Low cost: no one-time large investment, on-demand purchase, flexible payment, flexible response to business changes.
Controllability: As an ECS user, you have the rights of a super administrator and can fully control the OPERATING system of an ECS instance, solve system problems on the management terminal, and deploy the environment and install software.
Ease of use: Rich operating systems and application software. An image can be deployed with one click. The environment can be quickly replicated in multiple ECS instances and easily expanded; You can create ECS instances in batches using customized mirrors and disk snapshots.
API interface: use ECS API call management, through the security group function to access one or more ECS instances, make development and use more convenient.
disadvantage
Users are required to have a strong technical background, and the use of cloud computing needs to be familiar with and understand the process.
