Cloud Platforms and Platform Engineering

A Cloud Platform and Platform Engineering are closely related but serve different roles within the broader landscape of cloud computing and software development. Understanding how they fit together is essential for grasping how modern infrastructure and development practices are evolving.

How a Cloud Platform Fits with Platform Engineering:

1. Foundation and Building Blocks:

   • Cloud Platform: Provides the foundational infrastructure (compute, storage, networking, etc.) and a wide array of services (databases, analytics, security tools) that organizations use to build and run applications. It abstracts the complexities of managing physical hardware, data centers, and low-level infrastructure.
   • Platform Engineering: Utilizes these building blocks provided by the cloud platform to design, create, and manage a platform tailored to the needs of developers and operations teams within an organization. Platform Engineering focuses on building a cohesive and integrated environment that makes it easier for developers to build, test, and deploy applications.

2. Abstraction and User Experience:

   • Cloud Platform: Offers raw, flexible services that users can configure and combine in various ways to meet their needs. However, these services often require significant expertise to set up and optimize effectively.
   • Platform Engineering: Builds on top of these services, abstracting away even more complexity and providing a streamlined, user-friendly experience. This might include creating self-service portals, automated pipelines, and standardized environments that make it easier for developers to deploy code without needing deep knowledge of the underlying cloud infrastructure.

3. Automation and Integration:

   • Cloud Platform: Provides the tools and APIs necessary for automation (e.g., provisioning VMs, setting up networks, deploying applications). However, it's up to the user to stitch these together into automated workflows.
   • Platform Engineering: Engineers these workflows, integrating various cloud services into cohesive pipelines that automate repetitive tasks, enforce best practices, and ensure consistency across environments. This might involve creating CI/CD pipelines, infrastructure as code (IaC) templates, and automated security checks.

4. Customization and Flexibility:

   • Cloud Platform: Offers a wide range of customizable services that can be tailored to meet specific needs. However, these customizations often require a deep understanding of the cloud platform's capabilities and limitations.
   • Platform Engineering: Leverages this flexibility to build platforms that are specifically tailored to the organization’s needs. This might involve creating custom middleware, selecting the right mix of services, or integrating third-party tools to fill gaps in the cloud platform's offerings.

5. Security and Compliance:

   • Cloud Platform: Provides tools and services for security (e.g., IAM, encryption, firewall management) and compliance (e.g., audit logs, regulatory certifications). However, these need to be configured and managed appropriately.
   • Platform Engineering: Embeds security and compliance into the platform by designing systems that automate security practices, enforce compliance policies, and provide monitoring and alerting capabilities. This ensures that security is not an afterthought but an integral part of the platform.

6. Support for Multi-Cloud and Hybrid Environments:

   • Cloud Platform: Typically focuses on its own ecosystem, though many offer some degree of interoperability with other platforms.
   • Platform Engineering: Often needs to work across multiple cloud platforms or integrate on-premises systems with cloud environments. Platform engineers design solutions that are portable, flexible, and capable of operating across different cloud providers, ensuring consistency and reliability regardless of the underlying infrastructure.

How They Fit Together

• Cloud Platform: Acts as the foundational layer that provides the raw infrastructure, services, and tools necessary for running applications and managing data in the cloud.
• Platform Engineering: Builds on top of this foundational layer, crafting a cohesive and optimized platform that enhances developer productivity, ensures operational efficiency, and abstracts away the complexities of cloud management.

In essence, Platform Engineering adds value by creating a tailored, user-centric experience on top of the Cloud Platform's raw capabilities. It takes the flexible but often complex offerings of a Cloud Platform and turns them into something that developers and operations teams can use effectively without needing to manage every detail of the underlying infrastructure. This relationship is synergistic: Cloud Platforms provide the essential services, and Platform Engineering refines and optimizes these services to meet specific organizational needs.
