Undersea Small Column Learning English belongs to Chengdu Chuanggan Times Technology Co., Ltd. It is an English learning APP authorized by Wanda Baby King's global exclusive legal education. On the basis of the traditional "North American real foreign teachers" immersive teaching and the Cambridge children's teaching system, the submarine small column learns English. It combines AI artificial intelligence, cloud computing and motion capture and other advanced technologies with education and is fully integrated and widely used, bringing the world-class head Children’s IP is adapted into a systematic EQ English Enlightenment APP for young children (focus on 2-8 years old), which aims to promote Chinese children’s English listening, speaking, reading, writing, and viewing.
The submarine small column learning English initially adopted the self-built K8s cluster method for computing resource management and business deployment. With the growth of business scale, this method exposed some typical problems:
- Complex operation and maintenance: K8s clusters need to be maintained, black screen operation and maintenance are required, and each dependent cloud product needs to be integrated one by one.
- Low iteration efficiency: R&D is not only busy with business, but also responsible for the development and operation and maintenance of underlying components, which is inefficient.
- High cost: It is necessary to maintain a fixed IaaS host for a long time, and idle resources during the low peak period of the business are wasteful.
- Capacity assessment: Lack of automation, multiple assessments based on manual work, and often inaccurate assessment results.
- Stability issues: Development and operation personnel may misuse K8s YAML and underlying resources, causing cluster accidents to be unavailable.
Solutions and advantages
The Alibaba Cloud Serveless application engine SAE has the characteristics of free operation and maintenance IaaS, on-demand use, pay -as-you-go, low-threshold service applications to the cloud, and supports multiple languages and high flexibility, which perfectly solves the customer’s long-term complex operation and maintenance , Low resource utilization, low development iteration efficiency and other issues.
When a customer migrates from a self-built K8s cluster to SAE, there is no need to modify the business code, and only need to use Jenkins and the bastion machine to easily connect SAE with the original self-built operation and maintenance system. Because the customer belongs to the online education industry, its business traffic is obviously tidal, and Serverless's inherent extreme flexibility is just in line with the customer's needs and pain points. Therefore, after customers migrate to SAE, SAE is used as an on-demand, pay-as-you-go computing resource pool.
At the same time, as an application PaaS, SAE shields the underlying complex K8s operation and maintenance, and provides complete application lifecycle management and monitoring capabilities; and SAE can integrate various cloud products to provide one-stop services, and can integrate storage and network , Database, log and other components. Based on the above various characteristics, SAE can help the operation and maintenance personnel to liberate from the heavy operation and maintenance work, and greatly improve the production efficiency.
What advantages does SAE bring to the small submarine column to learn English?
- Zero transformation : Business codes such as microservices or monolithic applications can be transformed to enjoy serverless dividends.
- Flexible cost reduction: The cost of the test environment is reduced by more than 2/3 through one-click timing start and stop; through the second-level automatic flexibility of SAE, dynamic expansion can easily cope with the peak test, and the peak and valley automatically shrinks on demand to ensure the system SLA at the same time, Compared with the previous ECS holding method, it saves about 1/4 of the hardware cost.
- Free operation and maintenance to improve efficiency : Free operation and maintenance of K8s clusters and IaaS hosts, allowing developers to focus more on the business itself. At the same time, it is directly deployed to SAE through Jenkins and Maven plug-ins, simplifying the complexity of operation and maintenance.
- Stability : The stability of the microservice components + K8s cluster is covered by the platform, and SAE does not expose the native K8s. Customers also isolate resources through the bastion machine, effectively avoiding production environment failures caused by developers' misoperations.
- Service integration, one-stop experience : SAE automatically integrates Alibaba Cloud's various infrastructure products, micro-service ecological peripheral products, DevOps products, etc., providing a one-stop solution out of the box.
