Question

What is the typical application structure in Windows Azure? What type of communication is used to exchange data between application components and why?

Answer 1

Microsoft Azure is one such cloud service provider which provides the three type of  cloud services (infrastructure as a service,platform as a service ,software as a service)on a pay-as-you-go basis. Azure is highly efficient and intuitive for building and testing applications. It has built-in Developed operating system functionalities that are tremendously effective in streamlining the development to deployment pipeline. Apart from this, Azure has a host of services germane to business analytics, Machine Learning and Artificial Intelligence. The services are highly scalable (size can be varied) and can be tuned in a click of a mouse.

It provides a Computing platform and acts as an online portal for users to access and manage resources and services provided by Microsoft. It also offers a wide range of services that are spread across a wide range of domains.

application structure includes:

• compute- this has virtual machines,Functions for serverless computing, Batch for container batch workloads, Service Fabric for microservices and container orchestration, and Cloud Services for building cloud-based apps and APIs.
• networking-Load balancer , Application Gateway, vpn gateway, Azure dns for domain hosting, Content Delivery Network, Traffic Manager, expressroute dedicated private network fiber connections; and Network Watcher monitoring and diagnostics.
• storage- Includes blob, queue, file and disk Storage, as well as a data Lake Store, Backup and Site Recovery, among others.
• container-Azure has a property which includes Container Service, which supports kubernetes, DC/OS or Docker Swarm, and Container Registry, as well as tools for microservices .
• databases-azure has also includes several SQL-based databases and related tools.
• internet of things-Includes IoT Hub and IoT Edge services that can be combined with a variety of machine learning, analytics, and communications services.

communication

four types:-

• Event Hubs- which provide event and telemetry ingress to the cloud at massive scale, with low latency and high reliability. For example an event hub can be used to track data from cell phones such as a GPS location coordinate in real time.
• Queues-which allow one-directional communication. A sender application would send the message to the service bus queue, and a receiver would read from the queue. Though there can be multiple readers for the queue only one would process a single message.
• Topics-which provide one-directional communication using a subscriber pattern. It is similar to a queue, however each subscriber will receive a copy of the message sent to a Topic. Optionally the subscriber can filter out messages based on specific criteria defined by the subscriber.
• Relays-which provide bi-directional communication. Unlike queues and topics, a relay doesn't store in-flight messages in its own memory. Instead, it just passes them on to the destination application.
