About the small and medium companies on the cloud server cloud or not, individuals cloud Ali, Tencent cloud the situation now, the cloud on the proposal.
Big companies have money, not the scope of the following
1, reduce employment costs
Such as the use of cloud servers such as rds database, can be used directly, for example, to the application server nginx, php, java may need to compile a little trouble, it will not just docker on the line
Generally small and medium companies, operation and maintenance + a technical manager, technical manager to identify specific technical solutions, operation and maintenance of the implementation of the basic OK
2, reducing the service, maintenance time
rds mysql database can basically be used directly, oss basic storage is used directly, SMS interfaces are also many basic server api calls can be used directly, do not need much time to deal with their own, do a master multi-slave mysql
Only you need to configure
3, try to reduce some of the costs caused by the choice of technology selection, including the cost of time and money
In fact, technology selection is a complex matter, especially java ecology, N sets out a simple application of technical solutions, continue to try, the result of the project is still stable molding, the company comes to an end, time is life for many companies, is money,
java biologically rich, many alternatives, leading to a somewhat morbid status quo, because biologically rich, with better technology, higher wages, improved technology of java development, high wages for a reason,
Use some of Ali cloud-related services, such as queue service directly to the api, do not control the underlying cloud Ali particular the specific use of mq, or active q, or what, there are a number of services such as gateway
Of course, the need for special services, cloud services may not be met, we need to build their own, such a situation, there are also, but now the reuse of basic services, and now cloud will provide the corresponding product.
4, application availability, stability of cloud services, is higher than the self-built room
Ali cloud may be a few years ago, Tencent cloud stable some worse, but several years of development, stability has been greatly improved, the engine room unless a large area power outage, dns hung up, with virtually no application is not available but I say hang up, that is not possible,
Regardless to say, Ali cloud system to do such a big cloud service, certainly better than small companies do to improve and mature
5, in fact, almost overhead costs
Self-built room, perfect little room, cost at least hundreds of thousands, now a general application server 8g + a 4-core database about 2 nuclear 4g will 1W5, if you encounter events will be cheaper, about five years 8-10W, If the pre-built room, adding a server
2U Dell machines will 2W up and down, 5 years if basic hardware damage, will 3W up and down, really to be cheaper, but with labor costs, it cheaper 8K * 12 * 5, the cost of bringing stability to the room expensive than the server.
6, transfer, migration, upgrade costs
Self-built room, there is a great deal of trouble after the operation and maintenance personnel transfer, if the transfer is not successful, there will be a lot of legacy issues that will pile up much bigger, and eventually become a technical debt,
For example, because the company moved, the room would need to be relocated, which becomes very troublesome, if done the room will certainly be migrated Experience
Such as the need to upgrade in the room, it would be boring, and if people are not pre-built room liability, no label, basically less likely to be upgraded
7, optimize costs, related services
Ali cloud will provide a lot of services corresponding to various services, you do not need to spend a lot of time to write the script, build log analysis system, etc., cloud services provide corresponding services are basically free, greatly reducing your go the cost of inspection
Especially complex sql analysis of the complexity of the project inside the business, it is really time-consuming and energy,
If you are accustomed to using cloud services, it would correspond to lower yourself to use tools, including third-party applications and comes with a tool, the ability to log analysis, but still convenient cloud service
