how about alibaba cloud general computing power u1 instance? price/performance ratio, performance runaway score, and full analysis of applicable scenarios
When enterprises buy cloud servers, the most headache is "selection". In the past, when people chose machines in ariyun, the logic was very direct: either buy lightweight application servers or enterprise-class exclusive servers (such as c6/g6/c7/g7), or else choose "burst performance t5/t6", which is cheap but has a bottleneck in computing power ".
But in recent years, Aliyun has launched a very bright "all-gold" main model--
general computing force type u1 instance (Universal Instance)
. Many friends are asking:
What about the u1 instance? Is it a shared type? Will the CPU be limited? Is the price/performance ratio really as high as the official said?
Today, from the perspective of a person who has been engaged in SEO optimization and website architecture optimization for many years, I do not apply official public relations vocabulary, but use vernacular and measured logic to make the u1 example clear.
1. core truth: what kind of "species" is u1 instance "?
When many people hear the word "general" or see that the price is cheap, their first reaction is: "is this the kind of cheating model that uses CPU points to deduct fees?"
Directly to the conclusion:
No! The u1 instance is an enterprise-level instance with 100 percent exclusive computing power!
Previous enterprise models (such as g6, c7) are expensive because they are strictly limited to a specific generation of Intel or AMD hardware CPU chips. the technical essence of alibaba cloud u1 instance is:
Opened and consolidated multi-generational pool of enterprise-class hardware resources
. Through the underlying Shenlong architecture, Alibaba Cloud shields all kinds of enterprise-level hardware from differences and abstracts standardized benchmark computing power for users to use.
💡Big vernacular summary: u1 instance is like "enterprise cloud server hardcover room". You don't have to specify which generation of chips to use. Aliyun guarantees you 100 of the full computing power. However, because the hardware pool has achieved the ultimate resource scheduling and utilization, the purchase price is directly 30% ~ 40% cheaper than that of traditional enterprise models of the same specification!
2. cost analysis: what is better than t6? How much cheaper than c7/g7?
When we build a station selection or deploy an enterprise application, cost performance is always the core indicator. We can make a horizontal comparison between the u1 instance and the other two types of models commonly available on the market:
Comparison dimension
Burst performance type (t5/t6)
Universal Calculation Force Type u1 Example
Traditional Enterprise (c7/g7/c8i)
Calculation force provided
Limit CPU baseline (such as 20% ~ 30%), timeout stuck
100% vCPU power output continuously
100% vCPU power output continuously
Processor ratio
Fixed specifications
1:1 / 1:2 / 1:4 / 1:8 full coverage
Strict classification by c(1:2), g(1:4), r(1:8)
Price range
Extremely low, but only suitable for extremely lightweight testing
Moderately low (king of cost performance)
High (specify latest hardware generation)
Stability
Performance
When the traffic increases suddenly, it is easy to lose packets and time out, which is extremely damaging to SEO.
Extremely smooth performance for long-term business
Top performance for extreme high concurrency
As can be seen from the above table, the biggest advantage of u1 is
Eliminated the "sudden performance type" of the calculation of the power card ton hidden dangers, but sold close to the price of the shared type.
. For small and medium-sized enterprises and large and medium-sized websites, this price-performance ratio is simply killer.
3. performance measurement and running score performance (taking 4-core 16G configuration as an example)
In the actual test, we take one
u1.2xlarge(4 cores 16G)
Deploy a typical Linux + Nginx + MySQL + PHP architecture, and use Sysbench and UnixBench for running and concurrent stress tests:
1. CPU calculation power and running score performance
Sysbench CPU pressure measurement (20,000 prime number calculation): single-core and multi-core score performance is extremely stable, the processing speed is the same as that of standard 5-generation/6-generation enterprise models, and there is no phenomenon of CPU Steal (computing power is preempted).
UnixBench comprehensive running score: quad-core full load score easily exceeded 4,200 + points. For most Web dynamic rendering and API interface responses, the computing power is completely excessive.
2. Network packet and disk I/O
U1 instances support cloud disks and ESSD AutoPL cloud disks by default. Measured random 4K read and write IOPS can easily run over the cloud disk base limit. With Alibaba Cloud Full Site Acceleration (DCDN), the website Core Web Vitals(TTFB first byte response time) can be stably maintained
100ms - 200ms
The excellent range, the search engine spider crawl is very friendly.
What application scenarios are 4. U1 instances suitable?
With a flexible CPU: memory ratio (from 1:1 to 1:8),u1 can eat almost 80% of the business scenarios of small and medium-sized enterprises:
The official website of small and medium-sized enterprises and high-traffic blogs (daily average 10000~150000 PV): with CDN dynamic and static separation, u1 2 core 4G or 4 core 8G can easily withstand high concurrent access.
Internal office system of the enterprise (OA, CRM, ERP, DingTalk micro-application): employees use it at high frequency in daily life, requiring the system to be stable and not stuck for 7x 24 hours, and the 100 exclusive computing power of u1 just matches.
E-commerce store management, cross-border e-commerce multi-account operation: cost-sensitive, while requiring a highly stable IP and operating environment.
Lightweight database and cache node: choose u1 specification with 1:4 or 1:8 memory ratio (such as 2 cores and 16G), which is very cost-effective to run Redis or lightweight MySQL.
5. Architect Selection Recommendations and Procurement Optimization
Don't blindly pursue the highest intergenerational model: if your business is not AI
For large model training, extremely high-frequency financial transactions, or ultra-large game servers, there is no need to spend a lot of money to buy c8i or g8i. The money saved by u1 instances is added to the bandwidth or RDS database to earn more money.
Make good use of enterprise procurement channels and benefits: When building an enterprise cloud architecture, it is very important to plan accounts and budgets reasonably. if an enterprise needs to purchase multiple u1 instances in bulk or migrate large amounts of business, it is recommended to choose a compliant service channel to purchase and authenticate alibaba cloud accounts. usually, you can obtain enterprise-specific vouchers, new customer discounts, and one-to-one free selection guidance from architects, which greatly reduces O & M and hardware costs.
6. Summary
On the whole, the Alibaba Cloud Universal Computing Power u1 instance is currently available in the cloud server market.
Phenomenal products that balance "enterprise-class stability" and "extreme cost performance"
. It removes the cumbersome hardware intergenerational premium and uses 100 percent of the continuous and stable computing power output to solve the worries of small and medium-sized enterprises in building stations and deploying applications.
If your website or application is preparing to go online, and you want to control your budget while ensuring that it is not stuck and SEO-friendly, u1 instance is definitely the most recommended choice to close your eyes at present!
