云上的应用程序重构和 DevOps

沙特电信公司 (STC)

沙特电信公司 (STC)是中东领先的电信分销商，拥有超过 6000 名用户，提供移动计算、互联网服务等服务。

客户使用的是基于单体架构的应用程序，并且缺乏敏捷性和复杂的相互依赖关系。他们一直在进行广泛的手动测试，并努力保持发布正常。由于他们的框架过时，采用新框架并实施需要重新部署整个应用程序的持续部署成为一项艰巨的任务。

借助 DevOps 服务，它帮助他们将多个应用程序重新架构为微服务架构，该架构是多租户并支持数据存储和“共享一切模型”。部署架构旨在使用 AWS 的各种托管服务。虽然公共服务被构建为平台共享服务，但为应用程序的每个关键功能领域（如支付、订单等）提供了单独的服务。这些微服务是使用 EKS 交付的。

该解决方案通过使用事件驱动机制进行服务间通信，帮助他们减少微服务之间的直接通信。

• The implementation of the microservice architecture and AWS deployment architecture by Aspire Systems significantly improved STC's operational efficiency. The new architecture promoted flexibility, reduced dependencies, and allowed for quicker deployment. It also enabled multiple development teams to focus on different business areas of the applications, thereby improving productivity and efficiency. The phase-wise evolution of the application, facilitated by the adoption of emerging technologies, made the company more agile and responsive to new changes. The new system also supports concurrency of over 7000 during peak load, demonstrating its robustness and reliability.
