This article will explore the reasons for its emergence and core concepts, learn about its specific principles and components, its unique values and challenges, and discover key practices and standards.
Whether you are a business owner or a technical expert, here you will get valuable insights to enhance efficiency and competitiveness in today's rapidly evolving technological environment.
What is platform engineering?
Platform engineering is an approach where infrastructure, including a set of services, tools, processes, and approaches, is designed to facilitate the coordination and standardization of software development and ensure consistency in software development among different teams, providing them with their preferred level of abstraction, thus allowing them to focus on the development of new features and the quick launch of new applications, while engineering platform handles the operational aspects of the application lifecycle.
What's DevOps versus platform engineering versus Site Reliability engineering
Most platform engineering concepts, principles, and features overlap with DevOps and make you confuse it with Site Reliability Engineering (SRE). But these are all different things that have appeared at other times in response to additional industry challenges.
Initially, there was the traditional software development model where development and operations teams worked separately. This led to coordination issues, slowed down the software delivery process, and increased the number of errors. DevOps emerged as a response to these problems, erasing the boundaries between development and operations and fostering a culture of collaboration and automation, which together simplify the software delivery process and improve its quality. DevOps also include practices such as CI, CD, and containerization and orchestration tools.
This shift led to a rapid acceleration of software development, simplifying the creation of increasingly capable and more complex systems. However, ensuring the stability and reliability of the development of such systems became more challenging. In turn, Google introduced SRE as a response, detailed in a few books about SRE. This approach mostly overlaps with DevOps but emphasizes system reliability, introducing additional practices such as incident management, continuous process improvement, and tools like Service-Level Indicator (SLI) Service-Level Objectives (SLOs), and especially Service-Level Agreement (SLA) for measuring and improving system reliability.
However, the pace of development continued to increase, and the number of tools needed that responded to the industry's ever-changing requests. In response, the engineering platform emerged, carrying all the necessary and current practices and tools for consistent, efficient, and reliable development and its continuous improvement and standardization for specific companies.
Of course, the flexibility and adaptability of such a platform requires a cloud infrastructure, which asks for separate management so that developers can focus on specific tools, not their configuration. In response, GitOps emerged, representing an approach to managing this infrastructure through code.
All these approaches do not cancel but complement each other, sharing common principles, practices, and tools. The difference between them is that they have emerged in response to different industry demands and focus more on providing specific aspects of software development improvement.
Which concepts are behind platform engineering?
Given the accelerating technology advances and the growing data threats, the concepts platform engineering relies on are becoming increasingly important today, enabling them to provide reliable and adaptive software development.
- Flexibility is about how the system can adapt to changing requirements and conditions. It includes quickly adding new features, modifying existing ones, and integrating with other systems. This is important as it allows teams to respond quickly to new business requirements or technological trends.
- Scalability means the system can handle increasing load while maintaining performance and reliability. It includes adding additional resources to handle an increasing volume of data or requests and distributing the load among these resources to ensure stable operation. This is critically important for maintaining a high level of service as the business grows.
- Security is about protecting the system and data from threats. It includes modern encryption, authentication, and authorization methods, as well as implementing security policies and monitoring to detect and prevent potential threats. This is important for protecting valuable information and maintaining user trust.
Engineering platform principles
Now consider the principles of platform engineering, which ensure its capabilities and features.
- Modularity. It goes beyond simply dividing the system into independent services. It includes creating consistent interfaces and contracts between services, ensuring their compatibility and interaction. This allows development teams to implement and update services without the risk of disrupting the operation of other platform components. It also implies the ability to replace or update individual services without changing the entire platform, providing flexibility and resilience in the face of constantly changing requirements and technologies.
- Automation. It is not limited to simply reducing manual labor. It includes automating deployment, monitoring, scaling, and recovery processes for services. This ensures quick and reliable deployment of updates and quick detection and resolution of issues to maintain high effectiveness and availability of services.
- Standardization. It means not only using universally accepted standards and protocols but creating and adhering to internal standards and best practices in the design, development, testing, and deployment of services. This ensures consistency and quality of services throughout their lifecycle and simplifies their integration and interaction.
- Monitoring. It covers tracking the state and performance of services and collecting and analyzing metrics at all platform levels — from infrastructure to applications. This leads to universal optimization of performance and scalability and allows teams to quickly detect and resolve issues and predict and prevent potential problems.
Engineering platform components
There are many components that help to implement the above concepts and principles into a single system of continuously working tools. Let's consider them and their purpose.
- Cloud providers provide the basic infrastructure and services that all engineering platform infrastructure builds upon. These include computing resources, storage, networking, and various cloud platform services. So cloud providers offer the raw materials that the platform uses to build and run applications. Examples of cloud providers include the Azure Cloud platform, Google Cloud Platform, and Amazon Web Services.
- Infrastructure as Code (IaC) approach manages and provides computing infrastructure with code rather than physical hardware configuration or interactive configuration tools. So it allows for the automatic setup, modification, and management of infrastructure and makes it easier to manage and scale the infrastructure that supports your applications. Examples of IaC tools include Pulumi, Terraform, and Cloudformation.
- Infrastructure control plane is responsible for low-level managing the infrastructure resources and provides a unified interface for managing all the resources and services provided by the cloud provider, such as computing, storage, and networking, needed to run applications. Examples of Infrastructure control plane include Terraform Cloud, Atlantis, and Spacelift.
- Continuous Integration (CI) and Continuous Delivery (CD) are key approaches here. CI enables developers regularly merge their code changes into a shared repository, ensuring the codebase's integrity and that new features don't disrupt existing functionality. And CD follows CI, aiming to promptly build, test, and deploy new features to the platform. CI/CD creates a seamless pipeline for simple, swift, reliable software releases. Examples of CI/CD tools include Circle CI, Codefresh, Bitbucket Pipelines, GitLab CI, GitHub Actions, CodeBuild, Jenkins, Travis, Azure DevOps, and Google Cloud Build.
- Registry stores all CI/CD process build artifacts and lets you distribute Docker images with new platform features. Examples of registry tools include Docker Registry, JFrog Artifactory, Harbor, AWS ECR Registry, Azure Google Container Registry, and Google Container Registry.
- Kubernetes serves as a comprehensive platform orchestrator, managing containerized applications. It provides a unified interface for maintaining the desired state of a cluster and coordinates the deployment, scaling, and healing of applications, ensuring their efficient lifecycle management across the platform. Managed Kubernetes services like AWS EKS, GCP GKE, Azure AKS, and RedHat Openshift.
- Service catalog enables a catalog of services developers can use, a portal for developers to manage their applications, and a user interface for managing the platform. Once the platform orchestrator deploys and manages the feature, it is made available to other developers through the Service Catalog. Examples of such tools include Backstage, LeanIX, Port.
- Database & Storage makes the data persistence layer for applications and provision databases for storing structured data and storage systems for storing unstructured data of platform applications and features. Examples include Aiven, PostgreSQL, Redis, Amazon S3, MariaDB, Kafka, MySQL, Elasticsearch, and MongoDB.
- Messaging enables a system for sending and receiving messages between applications. It allows for asynchronous communication between applications and their features and can be used to decouple senders and receivers, making architectures more scalable. Examples of such tools include RabbitMQ, Kafka, and ActiveMQ.
- Security components include features like authentication, authorization, encryption, and security monitoring. It ensures that applications are secure, that data is protected, and new features development and use pose no threats to the platform. Examples of such tools include Azure Sentinel, Synk, Gremlin, Armo, and Tigera.
- Logging collects, stores, and analyzes log data from applications and infrastructure, allows for the monitoring and troubleshooting of applications and features' performance and usage, anddelivers insights into application performance and usage. Examples of such tools are Stackdriver, Fluentbit, Logz, and Datadog.
