What does API gateway do? The diagram below shows the detail. Step 1 - The client sends an HTTP request to the API gateway. Step 2 - The API gateway parses and validates the attributes in the HTTP request. Step 3 - The API gateway performs allow-list/deny-list checks. Step 4 - The API gateway talks to an identity provider for authentication and authorization. Step 5 - The rate limiting rules are applied to the request. If it is over the limit, the request is rejected. Steps 6 and 7 - Now that the request has passed basic checks, the API gateway finds the relevant service to route to by path matching. Step 8 - The API gateway transforms the request into the appropriate protocol and sends it to backend microservices. Steps 9-12: The API gateway can handle errors properly, and deals with faults if the error takes a longer time to recover (circuit break). It can also leverage ELK (Elastic-Logstash-Kibana) stack for logging and monitoring. We sometimes cache data in the API gateway.

Why is 𝗠𝗼𝗱𝗲𝗹 𝗥𝗲𝗴𝗶𝘀𝘁𝗿𝘆 so important in your MLOps Stack? Let's look again into the Machine Learning Model Training Lifecycle. 𝗟𝗲𝘁’𝘀 𝗿𝗲𝘃𝗶𝗲𝘄 𝘁𝗵𝗲 𝗺𝗼𝗱𝗲𝗹 𝘁𝗿𝗮𝗶𝗻𝗶𝗻𝗴 𝘀𝘁𝗲𝗽𝘀: 1: Version Control: Machine Learning Training Pipeline is defined in code, once merged to the main branch it is built and triggered. 2: Feature Preprocessing: Features are retrieved from the Feature Store, validated and passed to the next stage. Any feature related metadata that is tightly coupled to the Model being trained is saved to the Experiment Tracking System. 3: Model is trained and validated on Preprocessed Data, Model related metadata is saved to the Experiment Tracking System. 4: If Model Validation passes all checks - Model Artifact is passed to a Model Registry. The model is stored and ready to be packaged. 𝗧𝗵𝗶𝘀 𝗶𝘀 𝗶𝘁 - regardless of what deployment type will follow, the model is stored in The Model Registry. Model Registry is what glues Training and Deployment Pipelines together and this is where handover of the Model Artifact happens. 5: The same model can be packaged as a container for different deployment types by implementing a respective interface. E.g. - Flink application for Stream Processing Deployment. - gRPC API for Request-Response. - Plain model pointing to the Batch Serving Feature Store API for Batch. - 𝗧𝗵𝗶𝘀 𝗶𝘀 𝗴𝗼𝗼𝗱 𝗻𝗲𝘄𝘀 - as long as you are training your models using historical data the training pipeline is the same for any type of deployment. - It’s a different story when it comes to online training! You can find a more detailed explanation of different Model Deployment procedures in one of my previous Newsletter releases.

Top 3 API Gateway Use Cases. API gateway sits between the clients and services, providing API communications between them. 1. API gateway helps build an ecosystem. The users can leverage an API gateway to access a wider set of tools. The partners in the ecosystem collaborate with each other to provide better integrations for the users. 2. API gateway builds API marketplace The API marketplace hosts fundamental functionalities for everyone. The developers and businesses can easily develop or innovate in this ecosystem and sell APIs on the marketplace. 3. API gateway provides compatibility with multiple platforms When dealing with multiple platforms, an API gateway can help work across multiple complex architectures. – Subscribe to our weekly newsletter to get a Free System Design PDF (158 pages): bit.ly/3KCnWXq

How do we transform a system to be Cloud Native? The diagram below shows the action spectrum and adoption roadmap. You can use it as a blueprint for adopting cloud-native in your organization. For a company to adopt cloud native architecture, there are 6 aspects in the spectrum: 1. Application definition development 2. Orchestration and management 3. Runtime 4. Provisioning 5. Observability 6. Serverless Most companies start from Step 1 containerization and gradually adopt CI/CD, service orchestration. This microservice architecture significantly increases the number of instances to manage, so systematic testing and monitoring are required to increase plant observability. In fact, a lot of companies stop at Step 4 without moving to service mesh and cloud-native networking due to the complexity and the required DevOps talent.
