56. What is Reliable Services?

Ans:

Reliable Services in Azure Fabric are services addressing single or multiple business concerns. However they are different from the normal web services that we usually develop. By design they are reliable, scalable, highly available and consistent as they are hosted on multiple nodes, partitions and replicas in a cluster. Reliable services can easily access rest of Service Fabric APIs and due to this they can discover other services with ease, communicate with other services, can do health reporting and much more.

57. What are Reliable Actors?

Ans:

Reliable Actors are based on the Actor programming model. An actor has three primary components

• Code to achieve business functionality
• Storage to persist Service state
• Communication system or a mailbox queue to store messages sent by other actors that it will process.
• To achieve parallel processing the client can talk to multiple actors. Though the actors can run in parallel, each actor can process the messages it has received in its queue sequentially. In the case of Azure Service Fabric the actors are denoted as Virtual Actors. They are not explicitly created or destroyed in the memory, rather they get activated or created when the first call or invocation is made. The actor object gets destroyed when it is not used for some period of time. The Reliable Actor model is based on the top of the Reliable Stateful Service model. A Virtual Actor consists of Reliable Stateful Service that addresses the need to have code and a persistent state. The communication part is handled using Service Remoting

58. What are the benefits of using containers with Service Fabric?

Ans:

Compared to virtual machines, containers have the following advantages:

Small: Containers use a single storage space and layer versions and updates to increase efficiency.

Fast: Containers don’t have to boot an entire operating system, so they can start much faster–typically in seconds.

Portability: A containerized application image can be ported to run in the cloud, on premises, inside virtual machines, or directly on physical machines.

Resource governance: A container can limit the physical resources that it can consume on its host.

Ans:

• Text Analytics API is a suite of text analytics web services built with Azure Machine Learning. The API can be used to analyze unstructured text for tasks such as sentiment analysis and keyphrase extraction.
• The API returns a numeric score between 0 & 1. Scores close to 1 indicate positive sentiment, while scores close to 0 indicate negative sentiment.
• The advantage of this API is that a new model need not be designed and trained, the user only needs to bring the data and call the service to get the sentiment results.
• However, because this is only the initial release of this service only English is supported right now.
• How it works: Text Analytics API does not simply use a lexicon approach to map words such as “good or bad” to return the results.
• Instead, it uses advanced natural language processing techniques under the hood.

75. What is the difference between Table, Queue, and Blob storage?

Ans:

To use Azure Storage, you just need to have an Azure Storage Account. Using this account you can access the service of the Azure Storage. Actually, Azure Storage provides two types of storage accounts.

Standard Storage Account: It is for Blob, Table, and Queue Storage.

Premium Storage Account: It is for Azure Virtual Machine Disks Only.

BLOB STORAGE: It can store any type of data; data can be a document file, media file, exe or dll, images, text file or any other data file. So, basically, it is used for storing the objects. So, as the definition says, we can store large amounts of the unstructured data into the blob storage.

TABLE STORAGE: It is like a table inside the SQL Server. So, it is used to store the structured data. Table storage is a NoSQL key-attribute data store. It means every data stored in the table is stored with a typed property name. It is very fast when you are working with a large amount of data. It doesn’t use schema for developing the table.

QUEUE STORAGE: Sometimes, it is required to transfer the data in the format of the message over the internet between the two cloud services. In that scenario, we prefer to use the queue storage. You can create a large number of queues to process your data. Every queue contains a large number of the message and every message size may be up to 64 KB.

76. What are SQL Azure firewall rules?

Ans:

SQL Azure firewall rules are provided to protect the data and to prevent access restrictions to the SQL Azure database. Firewall grants access to the originating IP from which we are trying to access the database. In order to configure the firewall, we need to configure a range of acceptable IP addresses upon which we try to connect to the SQL Azure server using the Management Portal or with the SQL Server Management Studio. Let us see the step by step process of adding and deleting rules as per our IP configurations.

All-access to SQL Azure is blocked by a firewall.

By default Database created in SQL Azure is blocked by firewall for security reasons. Any attempt from external access or access from any azure application is blocked by a firewall.

77. What is Service Fabric in Azure?

Ans:

Azure Service Fabric is a next-generation middleware cloud platform to build scalable, reliable, and managed enterprise applications. Microsoft is already using Service Fabric powers in many of its products, including Azure SQL Database, Azure DocumentDB, Cortana, and Power BI.

• Develop massively scalable applications that are self-healing.
