Posted by Errin O'Connor on Sep, 30, 2021 06:09

In the contemporary industrial sector, the success of organizations across the globe is dependent on how they acquire, store and utilize big data to their absolute advantage. In this context, databases play a quite influential role in aiding organizations to use the data for deriving benefits. According to traditional means, the process of building a globally distributed database requires an insane amount of time and effort.

In addition to this, this database would require to be hosted at a data center of the interested organization using their connections and resources. To make the situation simpler, cloud computing and platform as a service (PAAS) concepts were developed. These helped companies across the globe to gain advantages of a globally distributed database with high scalability to run the business. Such platforms could then be deployed simply and managed by an individual itself. The features included in the Azure Cosmos DB Pricing provide all these advantages and much more.

The application has been developed by Microsoft to provide the user enterprises with the opportunity to set up a database that could be flexible and competent enough to tackle their organizational needs.

What is Microsoft Azure Cosmos DB:

Azure Cosmos DB

Microsoft has always been dedicated to helping organizations across the globe acquire, manage, analyze and beneficially store raw data through several software tools and applications. The Azure Cosmos DB is another example of the company’s efforts in the direction of making data management simpler.

In simple words, it can be described as a database service based on multiple models, with transparent scaling features that replicate organizational data to the locations of the users. This is a platform as a service offering that is distributed across the globe. One of the biggest advantages of using this application is the fact that the user company can manage their data even if it is distributively stored across global locations.

The application consists of the tools that the user company needs to scale data across global locations and computed resources. These tools are made available by Microsoft Azure which is one of the largest cloud providers in the world. This implies that in this Azure Cosmos DB pricing range, it has multi-region capabilities. Being a part of the cloud platforms, the application helps the user in managing a database system in an easy and hassle-free manner.

Features included in the AzureCosmos DB Pricing range:

The Azure Cosmos DB Pricing range provides the user companies with certain unique features including the horizontal scaling capacity, globally distributed database service across Azure regions, fully managed format, low latency, consistency model structure, and an API database capable of managing multiple queries at a large scale.

This implies that the product is well suited for organizations that require a system capable of handling critical workloads. The features can be enumerated in detail in the following manner:-

  • Globally distributed structure – The Cosmos DB can replicate organizational data on a global scale by adding Azure regions at a specific region rate.
  • Operational patternThe application is a part of the cloud services and works on a serverless operational pattern.
  • Multi-language support for several APIsThe Azure Cosmos DB acts as a hybrid platform and provides support to the data from several APIs like the Cassandra API, Gremlin API and others.
  • Multiple model structureThe Database of the application has a multiple model format which allows the development of model applications and the storage of data in several kinds of databases. These include graph-based, column family based databases and others.
  • High speed and low latency It is known for guaranteed 10-millisecond latency for 99% of reading and write consistency levels. This implies that the customers gain access to data at a higher speed and lower latency in comparison to other databases.
  • Analyzing with No-ETL analyticsThe application is also designed to enable the user company with the capacity of analyzing huge volumes of organizational data in a real-time format. This is done through the No-ETL pipelines and provides no impact on the performance of transactional storage and workloads.

Understanding the bill generating process of Azure Cosmos DB:

The explanations related to the billing heads can be given as follows:-

  • Database Operations The cost of all database operations including the relational databases and document databases are expressed as Request Units or (RU). Azure Cosmos DB has two operational models for databases which include the following:
Request Units

Provisioned throughput – is measured in the form of request units per second and is billed in the per hour format. It is perfect for the critical workloads that need high availability of data with low latency.

Serverless bills – the user company for the request units used for performing each of the database operations in this Azure Cosmos DB pricing model.

Provisioned throughput and Serverless
  • Consumed Storage   This storage head is billed in the form of GBs that are consumed by SSD backed data and index across all the Azure regions within which the organizational data of the user company is distributed into. Under this structure, two backup copies are provided with additional copies that are billed according to a certain GBs per copy format. The periodic backup when enabled is billed according to the GPS stored across the Azure Regions and the continued backup is billed for even the GPS of data that are restored per instance.
  • Dedicated Gateway The dedicated gateway head is billed on an hourly basis for each set of dedicated compute resources which are based on a selected number of cores and memory. A dedicated throughput mode requests the activation of backend partitions in the Cosmos DB account of the user company.
