With the continuous development of cutting-edge technologies and the popularity of cloud computing services, professional terms such as "cloud computing, cloud hosting, cloud servers, and elastic cloud servers" have appeared in people's sight.
If anyone asks what is cloud computing, cloud hosting, cloud server, elastic cloud server? Very few people can answer it. If you just look at the introduction from the supplier, it's hard to understand what it is?
In order to let everyone understand these technical terms more clearly, let me share with you today what is an elastic cloud server? To understand what an elastic cloud server is, we might as well ask ourselves what is a cloud server?
The definition of the cloud server is:
The cloud server is a simple, efficient, secure, reliable, and elastically scalable computing service. Its management is simpler and more efficient than physical servers. Users can quickly create or release any number of cloud servers without purchasing hardware in advance.
Cloud servers help you quickly build more stable and secure applications, reduce the difficulty of development and maintenance and overall IT costs, so that you can focus more on innovation in core business.
Alibaba Cloud Elastic Compute Service (ECS) offers elastic, secure, high-performance and cost-effective virtual cloud servers to cater all your needs. You can gain deep insights on ECS and integrate the best practices on the cloud to empower your business on our Academy Day Online Conference in March 5th, 2020 with free ACA Cloud Computing certification exams.https://www.alibabacloud.com/campaign/academy-day/academy-day-online Sign up free now!
After reading the definition, as a little white, I still do n’t understand, so I have to continue to look down. In the introduction of the advantages, Xiaobian seems to understand something, it is written like this:
Cloud computing servers (also known as cloud servers or cloud hosts) provide Internet-based infrastructure services to small and medium-sized users and high-end users. This user group is large and the demand for Internet host applications is increasing.
This user group has the following characteristics: the business is mainly host hosting and virtual private servers, some of which use hosting services, and large scale; focus on short-term return on investment, and have higher requirements on the price-performance ratio of products; strong personalization needs, tend to Value chain, fool products.
When users adopt traditional servers, due to many factors such as cost and operator choice, they have to face various difficult problems, and the introduction of elastic cloud computing servers effectively solves this problem.
Then explained the cloud server:
What is a cloud server?
Cloud computing server (also known as cloud server or cloud host) is a host product in the cloud computing service system. This product effectively solves the traditional physical host and VPS services, which have difficult management and weak business scalability. defect. Cloud hosts in practical applications have three areas of elasticity:
Hosting service configuration and business scale can be configured according to user needs and can be flexibly adjusted. The host service applied by the user can be quickly provisioned and deployed (real-time online activation), and achieves flexible and scalable billing methods in the cluster, users do not need to pay deposits, and there are multiple payment methods for users to choose.
Seeing here, I think everyone understands what a cloud server is. Now let's share what is an elastic cloud server?
The so-called elastic cloud server is an abbreviation of Elastic Compute Service. As the name implies, it is a computing service with elastic computing capacity.
ECS can be understood as a cloud server, as opposed to a physical server. ECS is a computing service that can be obtained by itself at any time and has a flexible and scalable processing capability. It helps users build a reliable, secure, flexible, and efficient application environment, ensures that the service runs stably, improves operation and maintenance efficiency, and reduces users' CAPEX and OPEX.
Compared with traditional physical servers, the ECS cloud server has more powerful features, such as Xinruiyun ECS elastic server. New Ruiyun ECS has the following 7 features:
Calculate ability
Provides elastic cloud servers with multiple specifications, types, and multiple network adapters to meet different usage scenarios.
Flexible calculation
According to business needs, cloud servers can be flexibly created and released to easily respond to rapid business changes.
Storage capacity
Supports mounting and backup of cloud hard disks. By mounting different types of cloud hard disks to achieve rapid expansion of the storage capacity of the host.
Rich mirroring
Supports public system mirroring, service integration mirroring, custom mirroring, and user local mirroring. Custom mirroring allows you to back up or create cloud servers at any time.
Snapshots and backups
Snapshots can back up and roll back data at a certain time of the cloud server. The snapshots are full snapshots, which improves security and reduces the difficulty of managing snapshots.
Powerful network functions
Provides secure, stable, high-speed, isolated network connections, has VPC functions, helps users build virtual private clouds, supports Layer 2 and Layer 3 network capabilities, and has functions such as firewall, load balancing, DDoS, private gateway, and VPN, enabling hybrid Cloud and cross-cloud deployments.
Cloud monitoring
Provide an open cloud monitoring service platform that provides real-time monitoring, alarming, and notification of resources.
