Ali cloud servers compared with normal IDC room or server vendor, Ali cloud ECS server with high availability, security and flexibility advantages. Wei Aisi blog from the above aspects in detail at the difference between these two and how to choose.
First, high availability
Ali cloud than ordinary IDC room using a more stringent standard IDC, server access standards as well as operation and maintenance standards to ensure the basic framework of cloud computing high availability, data reliability and high availability cloud server. That is relatively high stability.
Each geographical Ali cloud provided there is more than the available area. When you need higher availability, service can build standby or active-active service deployment scenarios using multiple availability zones. For two three-center-oriented solutions for the financial sector, you can also build a higher service availability through multi-regional and multi-usable area. These include disaster recovery, backup and other services, Ali cloud has a very mature solution. If a problem area is available, you can quickly switch to an available area of up easy, non-stop service.
Enhance the availability of goods and services. Including cloud server ECS, load balancing SLB, relational database and data migration services RDS DTS and so on.
Industry partners and eco-partners. Help you with a more stable structure, and ensure continuity of service.
A variety of training services. Let your business from the bottom end to end service, high availability on the entire link.
Second, security
Ali goes through a variety of international safety standards, including ISO27001, MTCS and so on. Security compliance for privacy and the protection of user privacy of user data privacy, user information have very strict requirements.
In the network construction, it is recommended that you use a proprietary network cloud Ali VPC. Proprietary network provides a stable, secure, fast delivery, self-controlled network environment. For traditional industries and not touching the cloud computing industry and business, with the ability to mix a proprietary network architectures and hybrid cloud cloud will enjoy cloud computing technology brought dividends.
Rich network products system: simple configuration, it is possible in the current business environment, with all rooms worldwide concatenated, thereby improving the development of business agility, stability and business.
IDC room interconnected with self-built: Ali proprietary cloud network can establish high-speed access to your existing IDC room, forming a hybrid cloud architecture. Ali cloud provides a variety of hybrid cloud solutions and extensive network products, to create a strong network functions, to make your business more flexible.
Stability private network: built on a proprietary network services, and network infrastructure will evolve constantly, so you have to update the network architecture and network function updated every day, so that your business will always remain in a stable status.
The security of a private network: the face of constant attack traffic on the Internet, private networks have natural traffic isolation and attack isolation. After the service set up on a private network, a proprietary network will build the first line of defense business.
Third, the elasticity
Cloud computing's greatest strength lies in the flexibility and agility. Ali cloud has the ability to create a medium-sized IT resources needed for the Internet company in a matter of minutes, to ensure that the majority of enterprises in the cloud services are constructed to withstand huge traffic pressure.
Ali cloud elasticity reflects the elasticity of the elastic storage, elastic and resilient computing network re-planning for your business structure. You can use any way to the business combination, Ali cloud can meet your needs.
Elastic computing
i.e. a single station configuration changes in the cloud server ECS. IDC normal mode, it is difficult to achieve on a single server configuration changes. For Ali cloud, the cloud when you purchase a server or storage capacity of the ECS, you can freely change the configuration of the increase or decrease in the volume of business. Longitudinal elasticity on specific steps, see with lifting.
Transverse elasticity.
For the peak of a live game or application platforms emerge, if at IDC normal mode, you can not prepare resources immediately; they can use cloud computing elasticity ways to help you through this peak. When the peak business disappears and you can relieve excess resources to reduce business costs. Expansion and reduction of the use of transverse, with elastically stretchable Ali cloud can be done time quantitative stretching, or expanding and contracting in accordance with the traffic load. On the specific application of transverse elasticity, see What is resilient and elastic.
Elastic memory
when the data amount increases, for ordinary IDC program, you can only continue to increase the server, and this expansion of the number of servers is limited. Ali cloud provides you with vast amounts of storage, you can purchase on demand, to provide maximum protection for storage. Specific applications on storage resiliency, see the cloud disk expansion.
Network resiliency
Ali cloud VPC's proprietary network and general network configuration IDC room can be configured exactly the same, and can have a more flexible scalability. Ali cloud, you can achieve interoperability between each of the available area (room), security domain isolation, and flexible network configuration and planning.
Fourth, the advantages compared with ordinary IDC
Advantages cloud server ECS comparison with normal IDC shown in the following table.
