Using Microservices instead of full servers is much more efficient in regards to management and cost
Benefits:
No server management
Continuous scaling
Pay-for-value services
Built-in high availability
Suitable for event-driven and microservice architectures
Microservices are autonomous and specialized in their field
Simply compute code for a simple task. Same thing as Azure Functions
Can be event-driven and even layerd
No more than 15 minutes
Workloads that use more than 10 GB of memory are not suitable for Lambda
Containers can help migrate legacy applications
The price to run a Lambda function increases with the number of invocations, duration, and memory allocated
Containers can be continuously run at a fixed cost
Is a serverless orchestration service to manage workflows between multiple AWS services
Has state machines (workflows) that contain a series of event-driven states (steps)
Manages each workflow’s state, checkpoints, and restarts
Provides error handling capability
Can transfer data between states\
States can filter and manipulate data
Just like python story games. Depending on the the action/result different functions will be executed. All start with the initial task
Each one of these steps can be a Lambda function
Provides the ability to create, publish, and maintain REST, HTTP, and WebSocket APIs
Configurable traffic management, authorization, and resource access control
Provides access to AWS services and publicly accessible endpoints
Hosts multiple versions and stages of an application’s API
Establishes client usage plans to monetize and control APIs •Can cache common responses
Collection of routes and methods
Collection of routes and methods
Collection of WebSocket routes
For apps that require API management features, such as usage plans, payload validation, private API endpoints, and resource policies
For Microservices
For real-time applications
Supports cross-origin resource sharing (CORS
Suppors CORS
Establishes a session between client and backend services
Stateless
Lower latency and lower cost than REST APIs
API management features are validate payload schema and data transformations
Stateless
Stateful
