仅欧洲替代方案 MongoDB Atlas.

MongoDB Atlas is the managed MongoDB offering from MongoDB Inc., a publicly-traded US corporation. Atlas runs on AWS, Azure or GCP - meaning the data sits on a US-jurisdictional hyperscaler, managed by a US-jurisdictional database vendor. Two layers, both US. For sovereignty, the answer is either self-managed MongoDB on EU infrastructure (which we operate for clients) or migration to a different document/JSON-capable database under EU jurisdiction (typically PostgreSQL with JSONB, which covers 90% of MongoDB use cases).

"欧盟区域"不等于主权。四个问题决定一切。

数据驻留告诉你数据存放在哪里。主权则告诉你哪个法律体系可以强制访问。这四点的答案必须都成立 - 否则该技术栈就不具备主权性。

驻留

数据物理存储在哪里?

不只是笼统的“在云端” - 而是具体在哪个数据中心、哪个国家、受哪种司法管辖。

次级处理者

您的数据路径中还有谁?

每一个接触数据的供应商:CDN、邮件中继、错误追踪、分析管道。

司法管辖区

哪些法律可以强制披露?

总部位于美国的提供商受 FISA 702 和 CLOUD Act 管辖 - 即使数据存放在法兰克福也不例外。

密钥托管

谁实际持有加密密钥?

如果云服务商同时持有数据和密钥,无论签订何种 DPA,数据对其而言都是可读的。

失败 AWS · Azure · GCP · EU 区域

在司法管辖权和密钥托管上失败。

欧盟数据、美国母公司、默认路径中的美国次级处理者、供应商管理的密钥。

通过 Binadit 托管技术栈

四项全部通过。

托管在欧盟、由欧盟总部基础设施提供。默认路径中零美国次级处理者。客户持有或欧盟 KMS 密钥。在您的第 28 条 DPA 中按名称列出。

为什么团队正在退出 MongoDB Atlas

MongoDB Atlas exits we've scoped come from two angles: regulated workloads (healthcare, fintech) where the AWS-via-Atlas double-hop fails compliance, and cost reviews where Atlas's per-cluster pricing is genuinely high vs self-managed. The migration target depends on use case. For document-heavy workloads with complex aggregation, self-managed MongoDB on EU compute preserves the API surface. For workloads that are using MongoDB as a JSON store, migrating to PostgreSQL with JSONB is often simpler and cheaper long-term.

MongoDB Atlas 服务及其仅欧盟等效方案

迁移不是"换一个盒子"。下面的映射是我们为离开以下平台的客户运行的 MongoDB Atlas 基于 Schrems II 的考量 - 完全适用欧盟司法管辖,数据链路中不涉及美国母公司。

Atlas clusters (M10+)

我们改用什么
Binadit 托管云平台。MongoDB 副本集,或在文档模型并不复杂的场景下使用带 JSONB 的 PostgreSQL。
工程说明
对于纯 MongoDB 兼容性,在欧盟 bare metal 上自行管理是生产环境的标准模式。如果你不需要 MongoDB 特有功能,PostgreSQL JSONB 是更经济的替代方案。

Atlas Search (Lucene-based)

我们改用什么
Binadit 托管云平台。Elasticsearch 或 OpenSearch,较轻负载场景使用 MeiliSearch 或 Typesense。
工程说明
Atlas Search 底层基于 Lucene;标准的 Elasticsearch / OpenSearch 可以处理同等的工作负载。

Atlas Vector Search

我们改用什么
Binadit 托管云平台。PostgreSQL 上的 pgvector,或对于更大规模的嵌入向量集使用 Qdrant。
工程说明
Qdrant 是最强的欧盟主权向量数据库 - 具备生产级可用性,并明确受欧盟司法管辖。

App Services (Realm)

我们改用什么
Binadit 托管云平台。在 GitLab CI 中构建 Docker 镜像并部署到 Kubernetes,为每个分支提供审查环境。
工程说明
App Services 无论如何都将在 2025-2026 年间被弃用;迁移目标是在欧盟基础设施上搭建定制后端。

Atlas Stream Processing

我们改用什么
Binadit 托管云平台。Apache Kafka 或 Redpanda,兼容 Kafka 协议。
工程说明
对于流式工作负载,Kafka + Flink 是行业标准。

Atlas Triggers

我们改用什么
Binadit 托管云平台。PostgreSQL 触发器与 LISTEN/NOTIFY,或使用 Kubernetes CronJobs 执行定时任务。
工程说明
自托管 MongoDB 原生支持 change streams;PostgreSQL 则有自己的 LISTEN/NOTIFY 机制。

Atlas Online Archive

我们改用什么
Binadit 托管云平台。分层 MinIO 或 Ceph 存储池,通过生命周期规则将冷数据迁移至更廉价的磁盘。
工程说明
Online Archive 本质上是一种定期分层存储机制;可以用欧盟境内的 object storage 作为冷存储层来复现这种模式。

Charts (BI)

我们改用什么
Binadit 托管云平台。Apache Superset 或 Metabase,连接至您的数据仓库。
工程说明
Metabase 与 Atlas-Charts 最为相似;可在任何地方运行。

Data API / GraphQL

我们改用什么
Binadit 托管云平台。Traefik 或 Kong,在边缘层实现限流与 OIDC 认证。
工程说明
对于 PostgreSQL 后端,Hasura 可即时提供 GraphQL API。

Atlas Backup (Continuous)

我们改用什么
Binadit 托管云平台。使用 restic 和 pgBackRest 备份数据,Velero 备份 Kubernetes 状态,存储至隔离的欧盟存储。
工程说明
对于自行管理的 MongoDB,基于 oplog 的 PITR 是生产环境的标准模式;我们为客户运维这一方案。

我们如何迁移离开 MongoDB Atlas

典型的中端市场迁移分为三个阶段进行。以下数据假设工程团队规模为 6-10 人,应用程序技术栈复杂度中等。

  1. Days 1-5

    Use-case decision: Mongo or Postgres

    Audit query patterns. If you use Mongo-specific features (aggregation pipelines, change streams, Atlas Search complex queries) → self-managed MongoDB on EU. If you treat Mongo as a JSON store → migrate to PostgreSQL JSONB. Output: target architecture decision.

  2. Days 5-14

    Cluster provisioning + replication

    Self-managed MongoDB cluster (3-node replica set, EU bare metal) provisioned. Initial sync via Atlas Live Migration tool. Monitoring and backup configured.

  3. Weeks 2-4

    Application cutover

    Connection string changed. Read-only validation period. Cutover during low-traffic window. Atlas cluster decommissioned after verification.

5-year TCO on Atlas → self-managed MongoDB on EU bare metal: typically 70-85% cheaper at production scale. A typical M30 Atlas cluster ($2k+/month) is replaced by a 3-node dedicated MongoDB cluster we operate with comparable or better performance. The trade-off is operational responsibility, which is what we take on as the managed partner.

Atlas has EU regions on AWS Frankfurt - does that solve sovereignty?
No. Two layers of US jurisdiction: MongoDB Inc. (US-headquartered) and AWS (US-headquartered). The CLOUD Act applies to both. For Schrems II-strict workloads, both must be eliminated.
Should we move to PostgreSQL or self-managed MongoDB?
Depends on usage. If you use MongoDB-specific features (complex aggregation pipelines, $lookup, change streams across collections, Atlas Search), self-managed MongoDB on EU bare metal preserves the API. If MongoDB is mostly storing JSON documents with simple queries, PostgreSQL JSONB is cheaper, more capable for analytical queries, and simpler to operate.
How operational is self-managed MongoDB?
For a 3-node replica set with backups and monitoring, it requires real ops work - typically 2-4 hours per week of attention plus incident response. We operate this for clients as part of the managed-infrastructure relationship; it's a known pattern.
What about MongoDB's own self-hosted enterprise version?
MongoDB Enterprise Advanced runs on your infrastructure but the licence is from MongoDB Inc. - a US contracting party. For pure sovereignty, MongoDB Community Edition (open-source, AGPL) is the option. For most production workloads, Community is sufficient.
Atlas Vector Search is critical for our AI features. What's the EU equivalent?
Qdrant (DE-headquartered) is the strongest sovereign vector database. Qdrant Cloud has EU regions; Qdrant self-hosted is the same engine. Migration from Atlas Vector Search to Qdrant is straightforward (vectors are vectors), with the schema mapping being the only meaningful work.
How long does an Atlas exit take?
For a single replica-set workload with moderate data (50-200GB): 2-4 weeks. For sharded clusters or very large data: 6-12 weeks. The schedule is dominated by the live-migration phase, not the application-side changes.
