Enterprise application cloud solution 2: application switching cloud middleware to reduce operation and maintenance costs

1. The traditional thinking of enterprises using middleware is to use the community open source version, but the community open source middleware has many challenges in the enterprise application scenario. Typical challenges are: 1) weak capability of open source version (including security); 2) enterprises need to operate and maintain open source components (get software packages, deployment, upgrade, fallback, data backup and recovery, etc.), and the input cost is high; 3) the scalability of open source version is insufficient.

two。 Benefits from using Huawei Cloud PaaS cloud middleware: 1) providing enterprise-class cloud middleware services and backed by professional cloud vendors; 2) business personnel and operation and maintenance personnel no longer need to care about the underlying implementation technology of open source middleware, operation and maintenance personnel no longer need to care about the underlying implementation technology of open source middleware, and operation and maintenance personnel leave it to the platform itself; 3) make further commercial reinforcement and technical enhancements to the open source version.

Enterprise application cloud solution 3: application containerization, second elastic scaling, higher resource utilization

1. The challenges faced by traditional virtual machine applications are: 1) slow application online and long service expansion time; 2) low application interaction performance; 3) low resource utilization under the same business pressure.

two。 Huawei Cloud PaaS application containerization solution: 1) applications can be built and run based on container images, launched and expanded quickly, and scaled in seconds; 2) improve resource utilization and business interaction performance based on the characteristics of the container itself.

Enterprise application cloud solution 4: application micro-service, feature decoupling, quick launch

1. The challenges faced by traditional monomer applications are: 1) feature coupling is high, and it is difficult to maintain and expand; maintenance personnel need to master the whole code, and the impact of code modification is difficult to control; 2) features are slow online: adding new features requires a rerelease of the whole system, including unit testing, integration testing, online upgrades, etc. 3) Enterprise self-deployment development, difficult problem location and high cost: when enterprises use open source micro-service framework to transform, it will be difficult to locate the problem and high cost.

two。 Huawei Cloud PaaS provides micro-service solutions: 1) non-intrusive micro-service framework, supporting 4-step transformation and migration of applications; 2) providing mixed choreography of container and virtual applications to support progressive transformation of applications; 3) providing commercial APM services to support automatic operation and maintenance mechanisms such as application topology and call chain

Cloud 5 for Enterprise applications: software SaaS, Business Model change

1. Under the traditional mode, enterprises selling services face challenges: 1) each tenant needs case by case manual deployment; 2) there is no isolation between tenants; 3) multi-tenants need their own operation and maintenance, high cost and slow scalability.
