软件定义的网络:仅 PaaSSoftware Defined Networking: PaaS-only

实现平台即服务 (PaaS) 资源时,部署过程会自动创建一个假设的底层网络,该网络上的控制数量有限,包括负载均衡、端口阻止以及与其他 PaaS 服务的连接。When you implement a platform as a service (PaaS) resource, the deployment process automatically creates an assumed underlying network with a limited number of controls over that network, including load balancing, port blocking, and connections to other PaaS services.

在 Azure 中,可将多个 PaaS 资源类型 部署到虚拟网络连接到虚拟网络,并将这些资源与现有虚拟网络基础结构集成。In Azure, several PaaS resource types can be deployed into a virtual network or connected to a virtual network, integrating these resources with your existing virtual networking infrastructure. 需要在虚拟网络中部署其他服务,例如 应用服务环境Azure KUBERNETES Service (AKS) Service FabricOther services, such as App Service Environment, Azure Kubernetes Service (AKS), and Service Fabric must be deployed within a virtual network. 在许多情况下,仅限 PaaS 的网络体系结构(仅依赖于 PaaS 资源提供的默认本机网络功能)足以满足工作负荷的连接和流量管理要求。In many cases, a PaaS-only networking architecture, relying solely on the default native networking capabilities provided by PaaS resources, is sufficient to meet a workload's connectivity and traffic management requirements.

如果正在考虑仅限 PaaS 的网络体系结构,请确保验证所需的假设符合要求。If you're considering a PaaS only networking architecture, be sure you validate that the required assumptions align with your requirements.

仅限 PaaS 的假设PaaS-only assumptions

部署仅限 PaaS 的网络体系结构的前提是:Deploying a PaaS-only networking architecture assumes the following:

  • 正在部署的应用程序是独立的应用程序,或者仅依赖于不需要虚拟网络的其他 PaaS 资源。The application being deployed is a standalone application or depends only on other PaaS resources that do not require a virtual network.
  • IT 运营团队可以更新其工具、培训和流程,以支持独立 PaaS 应用程序的管理、配置和部署。Your IT operations teams can update their tools, training, and processes to support management, configuration, and deployment of standalone PaaS applications.
  • PaaS 应用程序不是包含 IaaS 资源的更广泛的云迁移工作的一部分。The PaaS application is not part of a broader cloud migration effort that will include IaaS resources.

这些假设是与部署仅限 PaaS 的网络一致的最低限定符。These assumptions are minimum qualifiers aligned to deploying a PaaS-only network. 虽然这种方法可能符合单一应用程序部署的要求,但每个云采用团队应考虑以下长期问题:While this approach may align with the requirements of a single application deployment, each cloud adoption team should consider these long-term questions:

  • 这种部署是否会扩大范围或规模,以要求访问其他非 PaaS 资源?Will this deployment expand in scope or scale to require access to other non-PaaS resources?
  • 是否计划在当前解决方案之外部署其他 PaaS?Are other PaaS deployments planned beyond the current solution?
  • 组织是否有计划进行其他未来的云迁移?Does the organization have plans for other future cloud migrations?

这些问题的答案不会妨碍团队选择仅限 PaaS 选项,但在做出最终决定之前应予以考虑。The answers to these questions would not preclude a team from choosing a PaaS only option but should be considered before making a final decision.
