Give a clear overview of API in Azure?
Ans: The
Test Analytics in API is a web service that is built with the Azure learning.

Ques: 8.
If the client gets disconnected from cache with the services state the probable
cause?
Ans: If
the client gets disconnected the causal factor can be distributed into two
categories:
The cause
on the operator side:
- There might be a failure in the transfer of the standard cache from one node to the other.
- While the service was processing and dispatching the cache got deployed.
- There was a server update or an automated VM maintenance.
The fault
on the client side:
- The application of the client accidentally got redeployed.
- The application on the client side got auto-scaling.
- The layer of the network on the client side altered.
- There was a transient error on the network node.
- The bound operation took more time.
- The upper limit of the bandwidth was reached.

The
primary aim or purpose of this file is to allow configuration changes in
production environment without downtime of your application.
Ques: 10.
What are different types of Azure blobs and difference between them?
Ans:
Azure storage has two type of blob – Block and Page.
BLOCK
BLOB:
1. Block
blob is ideal for sequential read, write operations.
2. Block
blobs should be natural choice for storing the various types of files such as
office file, pdf, mp3, video, byte array and so on.
3. The
data constitutes from various blocks and each block can have max size of 4MB.
4. Write
made to block blob using PutBlock is uncommitted and maintained only for 7
days. User have to call PutBlockList to commit the data permanently.
PAGE
BLOB:
1. Page
blob is ideal for random read, write operations.
2. Page
blob being “sparse” type of storage, is natural choice for storing .VHD files
backing the Azure Virtual Machines
3. The
data constitutes of various page ranges and each page should be in multiple of
512 bytes.
4. Write
made to page blob using PutPage is a direct commit.
Ques: 11.
What is the difference between Table Storage and SQL Azure Table?
Ans:
TABLE
STORAGE:
1. This
is NoSQL store on Azure
2. As
NoSQL, the data is stored in Key-Value pair combination and data is referred as
an Entity.
3. Schema
is not enforced while storing the data.
4.
Combination of partition and row key is treated as unique for an entity.
5. Can’t
have relationship between tables.
6. Being
key-value store, we can’t define objects such as Stored procedures, Views,
functions.
7.
General usage is observed for storing diagnostics information, error log
information.
SQL AZURE
TABLE
1. This
is relational store on Azure
2. The
data is stored in Rows and Columns combination.
3. Schema
is enforces while storing the data. If schema is violated, then error is
thrown.
4. User
can define various constraints such primary key, unique key.
5. We can
define relationships between tables such as foreign key.
6. We can
created Stored procedures, views, functions.
7. Used
widely in transaction based systems.

What are the other VNET options for achieving connectivity with on premise and
azure resources?
Ans: Site
to Site and express route are other options for achieving cross premises
connectivity. Site to site to specifically use when you have large number of
resources to be connected. In some cases, Site to Site or Point to Site
connectivity may introduce network latency as VPN created by these features
work on public infrastructure (Internet) only. To overcome on this situation
“Express Route” option can be taken which offers dedicated Leased Line based
offering to overcome on latency issue.

What is Azure Service Fabric?
Ans: Azure
Service Fabric is a distributed platform for deploying and managing
microservices and containers.
It allows the developers to focus on implementation which is scalable,
reliable, and manageable and not
be concerned about the infrastructure. It uses the Azure Service Fabric
Resource Provider.
It allows
developers to build applications which are composed of micro services.
These services run on pool of Virtual machines known as a cluster.
It allows the services to massively scale out. You can create clusters for Service Fabric in many environments such as Linux, on premise. The microservices you can build with Service Fabric can be stateful or stateless.
