In this video, learn about the private Azure Edge Zone ecosystem and how developers can create, deploy, and manage applications on the edge.
In the last article, we had a look at how to start with Azure DevOps: Getting Started With Audit Streaming With Event Grid
In the article, we will go to the next step to create a subscription and use webhook event handlers to view those logs in our Azure web application.

This article is a part of the series – Learn NoSQL in Azure where we explore Azure Cosmos DB as a part of the non-relational database system used widely for a variety of applications. Azure Cosmos DB is a part of Microsoft’s serverless databases on Azure which is highly scalable and distributed across all locations that run on Azure. It is offered as a platform as a service (PAAS) from Azure and you can develop databases that have a very high throughput and very low latency. Using Azure Cosmos DB, customers can replicate their data across multiple locations across the globe and also across multiple locations within the same region. This makes Cosmos DB a highly available database service with almost 99.999% availability for reads and writes for multi-region modes and almost 99.99% availability for single-region modes.
In this article, we will focus more on how Azure Cosmos DB works behind the scenes and how can you get started with it using the Azure Portal. We will also explore how Cosmos DB is priced and understand the pricing model in detail.
As already mentioned, Azure Cosmos DB is a multi-modal NoSQL database service that is geographically distributed across multiple Azure locations. This helps customers to deploy the databases across multiple locations around the globe. This is beneficial as it helps to reduce the read latency when the users use the application.
As you can see in the figure above, Azure Cosmos DB is distributed across the globe. Let’s suppose you have a web application that is hosted in India. In that case, the NoSQL database in India will be considered as the master database for writes and all the other databases can be considered as a read replicas. Whenever new data is generated, it is written to the database in India first and then it is synchronized with the other databases.
While maintaining data over multiple regions, the most common challenge is the latency as when the data is made available to the other databases. For example, when data is written to the database in India, users from India will be able to see that data sooner than users from the US. This is due to the latency in synchronization between the two regions. In order to overcome this, there are a few modes that customers can choose from and define how often or how soon they want their data to be made available in the other regions. Azure Cosmos DB offers five levels of consistency which are as follows:
In most common NoSQL databases, there are only two levels – Strong and Eventual. Strong being the most consistent level while Eventual is the least. However, as we move from Strong to Eventual, consistency decreases but availability and throughput increase. This is a trade-off that customers need to decide based on the criticality of their applications. If you want to read in more detail about the consistency levels, the official guide from Microsoft is the easiest to understand. You can refer to it here.
Now that we have some idea about working with the NoSQL database – Azure Cosmos DB on Azure, let us try to understand how the database is priced. In order to work with any cloud-based services, it is essential that you have a sound knowledge of how the services are charged, otherwise, you might end up paying something much higher than your expectations.
If you browse to the pricing page of Azure Cosmos DB, you can see that there are two modes in which the database services are billed.
Let’s learn about this in more detail.

In this article, you learn how to set up Azure Data Sync services. In addition, you will also learn how to create and set up a data sync group between Azure SQL database and on-premises SQL Server.
In this article, you will see:
Azure Data Sync —a synchronization service set up on an Azure SQL Database. This service synchronizes the data across multiple SQL databases. You can set up bi-directional data synchronization where data ingest and egest process happens between the SQL databases—It can be between Azure SQL database and on-premises and/or within the cloud Azure SQL database. At this moment, the only limitation is that it will not support Azure SQL Managed Instance.

During the recent Ignite virtual conference, Microsoft announced several updates for their Azure multi-cloud and edge hybrid offerings. These updates span from security innovations to new edge capabilities.
From its inception onward, Microsoft Azure has been hybrid by design, providing customers with services that allow ground to cloud and cloud to ground shifts of workloads. Moreover, Microsoft keeps expanding its cloud platform hybrid capabilities to allow customers to run their apps anywhere across on-premises, multi-cloud, and the edge. At Ignite, the public cloud vendor announced several innovations for Azure Arc, Stack, VMWare and Sphere.
At Ignite last year, Microsoft launched Azure Arc, a service allowing enterprises to bring Azure services and management to any infrastructure, including AWS and Google Cloud. This service was an addition to Microsoft’s Azure Hybrid portfolio, which also includes Azure Stack and Edge. Later in 2020, the service received an update with support for Kubernetes. Now Azure Arc has more capabilities with the new Azure Arc enabled data services in preview. Furthermore, the Azure Arc enabled servers are now generally available.
