• Data is retrieved from the Redis cache on future requests.
• Using Azure Cloud, Azure Redis cache delivers strong and secure caching techniques.

Ques 15. What is Azure Storage Key?

Ans. Depending on the project needs, an Azure storage key is required to authenticate access to Azure storage service data.

Authentication is performed using two sorts of storage keys:

• The primary access code
• To eliminate website or application unavailability, use a secondary access key.

Ques 16. What types of deployment environments does Azure offer?

Ans. There are two different deployment environments to choose from:

1. Staging Environment

The staging environment is used to test an application’s updates before releasing it to the public.

2. Production Environment

The production environment is where apps go live and where target consumers can access them via a DNS-friendly URL.

Ques 17. In Azure what is Role Instance?

Ans. A role instance is a virtual computer that executes application code based on running role specifications. According to the description in cloud service configuration files, multiple instances of a role are also permitted.

Ques 18. Describe Azure Fabric
