云原生数据库提供可扩展性和灵活性。了解它们与传统数据库的区别、主要优势、实际案例以及采用前需要考虑的挑战。

What are Cloud-Native Databases?

Cloud-native databases are built specifically for cloud environments, utilizing the scalability, elasticity, and distributed architecture of cloud infrastructure.

They’re constructed from the ground up to flourish in the cloud, unlike conventional databases, which were designed for on-premises surroundings and often struggle to adapt to the cloud’s active nature.

  • High scalability, availability, and cost efficiency are key considerations for customer satisfaction.
  • Some famous products in this category are Amazon DynamoDB, Google Cloud Spanner, and MongoDB Atlas.
  • 当您的应用程序需要高可扩展性、处理大量数据或希望最大限度地降低运营成本时,应使用云原生数据库。

云原生数据库和传统数据库之间有什么区别?

主要区别在于规模、架构以及实现可用性的方法。云原生数据库旨在水平添加节点,以在云中实现高可用性和高性能。另一方面,传统数据库通常计划进行垂直扩展,并且可能难以适应云的活跃特性。

云原生数据存储可以集成分布式架构、托管服务和按需付费定价等属性,这可能有助于它们与某些现代的、基于云的应用程序兼容。

使用云原生数据库的主要好处是什么?

易于扩展、高可用性、低成本和最小的功能开销是此类产品的一些公认优势。云原生数据库可以根据负载条件快速向上或向下扩展,这意味着数据库很少需要离线。 

按需付费服务提供基于使用情况的灵活付款方式,而完全托管的服务可能有助于减少手动配置和维护的需求。

组织在采用云原生数据库时应注意哪些挑战或考虑因素?

在操作中出现的新问题是相互关联的,包括供应商锁定、数据迁移以及部署和管理这些数据库的技能。

至关重要的是要考虑在数据迁移中出现可能的困难时,移动数据的难易程度,并清楚了解数据库管理经验或解决托管服务的可能性。

云原生数据库在实际应用中有哪些例子?

值得注意的例子包括:

  • Amazon DynamoDB: NoSQL数据库通常用于需要数据建模灵活性的高性能应用程序。
  • Google Cloud Spanner: 它在其关系数据库中利用跨多个位置的分布式架构,旨在同时实现数据一致性和服务可用性。
  • MongoDB Atlas: 一种面向文档的数据库,专为灵活性和可扩展性而设计,通常用于基于云的环境。
  •  Azure Cosmos DB: 这是一种托管在云端的数据库,可以处理不同的数据模型和协议。

行业应用案例包括电子商务平台、游戏应用程序和物联网设备。

在什么情况下,组织应考虑使用云原生数据库而不是传统或SaaS解决方案?

当您的应用程序需要高度时,请使用云原生数据库 可扩展 and available when you will process a large amount of data, when you want to spend minimal time on operations, or when creating new applications cloud-native.

Cloud-native databases are designed for the cloud environment. While they may offer advantages over traditional or SaaS solutions regarding scalability, flexibility, and cost-efficiency, these benefits may not be fully realized in the long run.

If your needs are relatively basic, and your demands can be easily predicted, then a SaaS solution would be the best place to start. Nevertheless, when your application gets more complicated and your company needs more independence and customization, a cloud-native database may be the best solution.

结论

Cloud-native databases are modifying the imperative of building and deploying applications. These services are characterized by scalability, availability, and cost-efficiency, which are important considerations for modern businesses. If you are faced with the necessity to consider options for further work with the database, you should think about all the requirements and peculiarities described in this article and decide whether the usage of the cloud-native database would be a good idea in your case.
