  • Hybrid Cloud: As the name itself says, this cloud model is the hybrid combination of private cloud and the public cloud.

This might include the scenario of using on-premise servers for processing confidential, sensitive data and using public cloud features for hosting public-facing applications.

112. What is the Azure SLA (Azure Service Level Agreement)?

  • The Azure Service Level Agreement is a contract that ensures or guarantees that when two or more role instances of a role are deployed on Azure, access to that cloud service is guaranteed for at least 99.95% of the time.
  • Azure SLA also states that if the role instance process is not in the running state, then the detection of such processes and corrective action for the same will be taken 99.9% percent of the time.
  • If the mentioned guarantees are not satisfied at any point in time, then Azure credits a percentage of monthly fees to us depending on the pricing model of the respective Azure services.

113. Define the best Azure solution for executing the code without a server?

  • Azure Functions service can be used for executing the code without a server.
  • Serverless Azure Functions are used for simplifying complex orchestration and challenging resolutions. They are meant for being stateless and short-lived.
  • They help to connect with other services without the need for hard coding of the integrations thereby making the development process faster.
  • It helps the developer to write and concentrate on the business logic code thereby saving time and effort.
  • They also provide the features of monitoring and analyzing code performance by means of Azure Application Insights that help in identifying bottlenecks and failure points across the components of the application.

114. Explain about Cspack in Azure and what is it primarily used for?

  • Cspack is a command-line tool that is used for generating service package files. The tool also helps in preparing the application for deployment in Microsoft Azure or compute emulator.
  • Every project of cloud service type has the .cscfg file which is basically the cloud service configuration file that is generated by means of Cspack tool and is primarily used to store:
    • The number of role instances for the deployment of each role in the project.
    • The thumbprint of the certificates.
    • User-defined configuration and settings.

115) Define the available options for deployment environments provided by Azure?

There are two deployment environments provides by Azure, they are:

  • Staging Environment: Staging environment is used for validating the changes of our application before making them live into the main environment.

Here, the application is identified by means of GUID (Globally Unique Identifier) of Azure which has the URL as: GUID.cloudapp.net

  • Production Environment: Production Environment is the main environment where our application goes live and can be accessed by the target audience which can be accessed by means of DNS friendly URL: appName.cloudapp.net.

116. What do we need to do when drive failure occurs?

Here are the following steps need to be performed when the drive failure occurs:

  • To make sure that the Azure Storage functions without fail, we need to ensure that the drive is not mounted.
  • Replace the drive so that the drive gets remounted and formatted.

117) Is there any possibility to design applications that handle connection failure in Azure?

It is possible and is done by means of the Transient Fault Handling Block. There can be multiple causes of transient failures while using the cloud environment:

 

  • Due to the presence of more load balancers, we can see that the application to database connections fail periodically.
  • While using multi-tenant services, the calls get slower and eventually time out because other applications are using resources to hit the same resource heavily.
  • The last cause can be we ourselves as the user trying to hit the resource very frequently which causes the service to deliberately deny the connection to us to support other tenants in the architecture.

 

  • Instead of showing errors to the user periodically, the application can recognize the errors that are transient and automatically try to perform the same operation again typically after some seconds with the hope of establishing the connection. 

 

  • We can generate the retry intervals and make the application perform retries by making use of the Transient Fault Handling Application Block mechanism. In the majority of the cases, the error would be resolved on the second try and hence the user need not be made aware of these errors unnecessarily.

 

  • Here is the sample code that can be used for the retry policy. If the connection is not successful, then the action is retried based on the retry policy defined. 
  • There are 3 retry strategies – Fixed Interval, Incremental Interval, Exponential Backoff Strategy.

 

/***

* Class to detect Transient Blocks – Here

* OperationCancelledException is 

* detected and then the retry strategy is employed.

*/

internal class AppTransientDetection : ITransientErrorDetectionStrategy

{

    bool IsTransient(Exception exception) => 

        exception is OperationCanceledException;

}

 

/***

* Retry Strategy – Here Fixed Interval Strategy is employed and is retried for 5 times.

*/

RetryStrategy retryStrategy = new FixedInterval(retryCount: 5, retryInterval: TimeSpan.FromSeconds(2));

 

RetryPolicy retryPolicy = new RetryPolicy(new AppTransientDetection(), retryStrategy);

retryPolicy.ExecuteAction(() => { 

    try { 

        string commandText = @”USE FEDERATION User_Federation(ShardId =” + shardId + “) WITH RESET, FILTERING=ON”; 

        userEntity.Connection.Open();

        userEntity.ExecuteStoreCommand(commandText); 

    } catch (Exception e) {

        userEntity.Connection.Close();

        SqlConnection.ClearAllPools(); 

    } 

});

119. Define Azure DevOps?

Azure DevOps is a SaaS platform that provides development services and it is used for creating work plans, working together on code, developing applications, and deploying them. 

It offers an end-to-end DevOps toolchain for the development and deployment of software. It is able to integrate with a number of popular tools in the market and is a great way for setting up a DevOps toolchain.

120) Define Azure Data Factory?

  • ADF is a serverless and cloud-based data integration service and platform and it is used for the creation of ETL and ELT pipelines. 
  • ADF helps in the creation of data-driven workflows for the planning and execution of data movements and data transformation at scale.

121. Define the 3 principal segments of the Windows Azure platform?

Windows Azure has 3 principal segments, there are: 

  • Compute
  • Storage
  • Fabric.
  • Windows Azure Compute – Windows Azure gives a code that can be managed by the hosting environment. It gives the calculation benefit through parts. Windows Azure backs three types of roles:

 

  • Web roles utilized for web application programming and upheld by IIS7
  • Worker roles utilized for foundation handling of web roles
  • Virtual machine (VM) roles utilized for moving windows server applications to Windows Azure in a simple way
  • Windows Azure Storage –   It gives four types of storage services:
    • Queues for informing between web parts and worker roles
    • Tables for storing structural data
    • BLOBs (Binary Large Objects) to store contents, records, or vast information
    • Windows Azure Drives (VHD) to mount a page BLOB. These can be transferred and downloaded by means of BLOBs

    • Windows Azure AppFabric –   AppFabric provides five services:
    Service bus
    • Access
    • Caching
    • Integration
    • Composite.
