Serverless container service offered by Microsoft Azure that simplifies deploying and managing containarized applications. One of the platform that containarized app is the Docker, it uses to encapsulate an application and its dependencies, libraries, and runtime environment, enabling the application to run consistently across different environment, such as development, testing, and production, without worring the differences in the underlying infrastructure.
Containers are lightweight, portable, and isolated environments that package the code, runtime, system tools, libraries, and settings within an application. This means they load more quickly, as they are isolated, limiting interference from other processes, enabling efficient resource utilization, using the OS kernel, and requiring fewer resources than running full virtual machines.
Are they secure?
Yes, since they are part of the Azure ecosystem, Azure employs layers of security measures to protect its resources.
- Identity and Access Management – Provides authentication and authorization controls to ensure that only authorized users can access resources.
- Network Security – Azure utilizes firewalls, network security groups to control traffic, and prevent unauthorized access. Additionally, security measures such as DDoS protection and the Azure firewall feature help secure against network threats.
- Security Center – Identifies potential vulnerabilities and recommends improvements to the security posture of resources. This feature also offers advanced threat detection and analysis.
- Encryption and Compliance – All data at rest and in transit are encrypted. Azure complies with standard setups and aligns with industry best practices.
- Sentinel – Offers continuous monitoring and logging to detect unusual activities or security threats. Azure Sentinel operates in the cloud and enables intelligent security analytics and threat response
Dapr –
Short for Distributed Application Runtime, is like a helpful toolkit for developers working on microservices-based applications. It’s an open-source platform that makes building these applications much simpler by providing a set of tools and simplified methods. This toolkit helps developers create distributed and event-driven applications with ease.
e-commerce company that operates across various channels like web, mobile, and in-store. They need a system to manage inventory in real-time across these different platforms while ensuring consistency and reliability.
Sample scenario:
Inventory Service: One microservice could handle inventory management. Dapr would assist in handling state management, allowing this service to keep track of available products and their quantities. Dapr’s state management capability could ensure consistency across different instances of this service and enable it to scale efficiently.
Event-Driven Updates: Whenever a product is purchased, a microservice responsible for order processing could emit an event using Dapr’s publish-subscribe capability. This event would notify the Inventory Service to update the inventory count in real-time.
Scaling and Resilience: Dapr’s building blocks help in scaling these services based on demand. It ensures that even if one part of the application encounters issues, the rest of the application remains operational due to Dapr’s fault tolerance capabilities.
In this microservices architecture, Dapr would act as a facilitator, enabling communication between services, managing state, and providing a standardized way for these services to interact with each other, leading to a more robust and scalable inventory management system across various channels.
