Understand the certification

OCI Developer 认证在 Oracle 生态内有用(ERP Cloud、Fusion Middleware 项目),但和 AWS/Azure 开发者认证相比市场需求量小一个数量级。

Oracle Cloud Infrastructure Developer 2020 Associate (1Z0-1084-20) 验证在 OCI 上开发和部署云原生应用的能力。55 题 / 105 分钟,及格线 65%(约 36 题),费用 $245 USD。覆盖 OCI 核心服务(Compute/Networking/Storage/IAM)、容器服务(OKE - Oracle Kubernetes Engine)、Serverless(OCI Functions 基于 Fn Project)、API Gateway、Streaming、Events 和 DevOps(Terraform + Resource Manager)。

OCI 在全球云市场份额约 2-3%(Synergy Research 2025),远小于 AWS(32%)和 Azure(23%),但 Oracle 的杀手锏是 Autonomous Database 和 Oracle ERP Cloud/Fusion Apps — 这两个领域没有替代品。用 OCI 的企业几乎都是因为已经深度使用 Oracle 数据库或 Oracle ERP,不是因为 OCI 的 IaaS 比 AWS 好。

这张证适合的场景很明确:你在做 Oracle Cloud 项目(ERP Cloud 实施、Autonomous Database 开发、从 on-prem Oracle 迁移到 OCI),需要证明你不只会用 Oracle 数据库,还懂 OCI 的云原生服务。

Included in your preparation

  • 55 practice questions focused on real OCI developer tasks
  • Coverage of containers, Functions, API Gateway, CLI, SDKs, and Terraform
  • Practical scenarios around events, streaming, and data services
  • Mock exam aligned to the official 105-minute format
  • Clear explanations that connect service choices to application design

1. 第一阶段:OCI 核心服务动手(2 周)

注册 OCI Free Tier(永久免费额度包含 2 个 AMD Compute、Autonomous Database、Object Storage)。走完官方 Get Started 教程:创建 VCN + Subnet、启动 Compute 实例、配置 Security List/NSG。理解 OCI 的 Compartment(资源隔离单元)和 IAM Policy 语法(Allow group X to manage Y in compartment Z)。

2. 第二阶段:容器 + Serverless + API(2 周)

用 OKE 部署一个简单的 Docker 容器应用;用 OCI Functions(基于 Fn Project 开源框架)写一个 HTTP trigger function;配置 API Gateway 路由到 Function。理解 OCI Events + Notifications + Streaming 的事件驱动架构模式。

3. 第三阶段:DevOps + 模考(2 周)

OCI Resource Manager(托管 Terraform)的 Stack 创建和 Plan/Apply 流程。OCI DevOps 服务的 Build Pipeline + Deployment Pipeline 配置。用 Oracle 官方 Practice Exam 和 Whizlabs OCI Developer 题库做模考,目标稳定 75%+。

Career value

OCI 相关岗位在澳洲的需求集中在 Oracle 合作伙伴(Accenture、Deloitte、DXC 的 Oracle Practice)和少数大企业的 Oracle 团队。薪资水平和 Oracle DBA/ERP 顾问相当,$100-150K AUD 区间。

这张证的独特价值在于 Oracle 生态的稀缺性 — 会 OCI 的人比会 AWS 的人少得多,竞争也小。如果你已经在 Oracle 技术栈里(DBA/PL-SQL/ERP),加一张 OCI 开发者认证能显著拓宽职业路径。

不适合的人群:没有 Oracle 技术背景想进云计算的人 — 直接考 AWS SAA-C03 或 AZ-104,市场需求大 10 倍以上。

Preparation tips

  • 55 题 105 分钟,约 2 分钟/题,时间还算充裕。
  • IAM Policy 语法是重中之重 — 记住格式 "Allow <subject> to <verb> <resource-type> in <location> where <conditions>",至少考 5 题。
  • OCI Free Tier 是最好的学习工具,所有考点都可以在 Free Tier 上实操验证。

Common mistakes

  • **Compartment 层级关系** — OCI 的资源隔离是通过 Compartment 树实现的,Policy 在 parent compartment 设置会继承到 child。很多人搞混 Compartment 和 Region 的关系(Compartment 是逻辑隔离,跨 Region 生效)。
  • **Security List vs NSG** — Security List 作用于整个 Subnet,NSG 作用于单个 VNIC。考试经常问"最小权限原则下应该用哪个",答案是 NSG。
  • **OCI Functions 的冷启动** — OCI Functions 基于 Fn Project,冷启动时间比 AWS Lambda 长,考试会问如何优化(provisioned concurrency 概念)。

我在 on-prem 做了 6 年 Oracle 数据库,公司决定迁到 OCI。考试里 OKE 和 Functions 占了不少分,这两块我之前完全没碰过。建议 DBA 出身的人重点学容器和 Serverless,数据库相关的题反而简单。

有 AWS 经验后学 OCI 很快 — 概念都能对应上(VCN ≈ VPC、Compartment ≈ Account/OU、OKE ≈ EKS)。最大的区别是 IAM Policy 语法完全不同,OCI 用自然语言式的 Policy Statement 而不是 JSON。这块考了 5-6 道。
