Azure Storages

In this article we can explore about Azure Storage.

Azure Storage

Azure Storage is a Microsoft managed Cloud Service.

Azure Storage is highly available, secured, durable, scalable and redundant.

Data Services

Azure Storage now contains 3 Data Services:

· Blob Storage

· File Storage

· Queue Storage

Blob Storage

Blobs are basically Files like excel, pictures etc.

Blobs are stored inside Containers similar to Folders.

Blob Storage provides URLs for Universal access.

File Storage

File Storage is like Network File Share.

File Storage uses SMB (Server Message Block) protocol.

File Storage provides URLs for Universal access.

Queue Storage

Queue Storage is to store messages.

Queues Storage is meant for Asynchronous communications.

Azure Cloud Types

In this article we can explore about Azure Cloud Types.

Cloud Type

Cloud Type determines the type of date, hosting & security aspects.

There are 3 Cloud Types in Azure:

· Public

· Private

· Hybrid

Public Cloud

Public is the default Cloud Type.

Public Cloud is available to General Public.

Public Cloud hosting is owned & managed by Microsoft.

Public Cloud is cheaper.

Public Cloud is less secure for sensitive data.

Private Cloud

Private Cloud offers more security to sensitive data.

Private Cloud is owned & managed by Single company.

Private Cloud is expensive.

Hybrid Cloud

Hybrid Cloud is combination of Public & Private cloud.

Hybrid Cloud offers right mix of cost & security.

Sensitive Data is a critical decision-making part in Cloud Type determination. For example, a client may have sensitive data like Names, Social Security Identification information, Private Accounting data etc. which they do not wanted another company to manage, not even Microsoft. Also, a company may have legal agreements with their clients that the client data will not be stored outside the country. In these cases, Azure offers Private cloud to the company where they can run the Azure infrastructure in the company owned servers & managed by company team. In this way Scalability, Availability & Flexibility of Azure platform can be reused while the Data Security is also addressed.

App Service

App Service is preferred if you want to host Apps like Web Apps, Mobile Apps etc.

App Service provides Scalability.

App Service is best for Single-tier applications.

App Service is cheaper.

Cloud Service

Cloud Service is preferred for n-tier applications.

Cloud Service provides High Availability & Scalability.

Cloud Service provides more control over the OS.
