Cloud computing is basically the commodification of data storage and computing time with the help of standardized technologies. Cloud databases are databases that run on cloud computing platforms such as Salesforce, GoGrid, Rackspace, and Amazon EC2. Users can independently run cloud databases on the cloud with either of the two deployment models - virtual-machine image or by purchasing access to database services that are maintained by cloud database providers.

Although cloud databases provide significant benefits over traditional deployments, sometimes traditional architectures should be integrated with cloud platforms. However, cloud databases have been providing a comprehensive solution for every customer who demands custom-built, high-performance infrastructure for a relational database supported and backed by MySQL-specialized engineers. Cloud databases are best suited for customers who are focused on getting their applications developed without getting hassled with infrastructure-related issues.

Here are the top 7 most beneficial cloud databases that are offering scalability for the customers to grow, based on their application needs:

What is a Cloud Database?

With the amount of information and data that businesses require these days to be successful, the major challenge is storing this data and information. Usually, any data or information is stored in databases, but again, these have limited capacities. This is where a cloud database comes in. A cloud database is a database that is created, maintained, stored and accessed in a cloud environment. These databases can be accessed through a web interface and offer functionality similar to traditional databases.

Why Use a Cloud Database?

For most companies, managing their own databases can be quite a costly affair and therefore these companies look for alternatives that can ease out the process of managing and storing data. Cloud databases offer several benefits to the users that include:

  • Reduced overall costs in terms of maintaining and expanding the database as per the data and information storage requirements.
  • Flexibility in storing, managing, and accessing data.
  • Easy scalability.
  • Easy access as cloud databases can also be accessed using mobile devices.
  • Cloud databases offer easy and quick recovery of data in case of a disaster or theft of data.
  • Greater security as cloud databases has enhanced security features that keep the data safe and sound.

Different Types of Cloud Database Management Systems

Cloud database management systems are those comprehensive systems that manage the cloud database for storing, maintaining, and accessing the data in the cloud environment. These management systems can be categorized into:

  • Relational cloud database management systems: These systems make use of tables that store data in a predefined relational manner. These systems make use of structured query languages to manipulate the data in the databases. The benefit of these systems is that they are highly reliable and offer great consistency when dealing with large amounts of data. Examples of these systems are: Spanner, Cloud SQL, and Oracle.
  • Non-relational cloud database management systems: These systems do not store data in a specific format, relation, or structure. The aim of using these systems is to store unstructured data like text messages, survey results, or media files.  Examples of these systems include MongoDB, Redis, and Hbase.

Gartner Magic Quadrant for Cloud Database Management Systems

The increased need for cloud databases has brought to the marketplace several players and vendors who offer these cloud services to various companies and making the right choice for the cloud database provider is a tough task. Gartner Magic Quadrant is a tool that enables users to find the best vendors and providers by providing a competitive analysis of all the major players. 

Using this tool, the various providers are divided into leaders, visionaries, niche players and challengers enabling the users to make the right decisions. 

Advantages of Working with Cloud Databases

Today, in the competitive and dynamic environment, most companies are shifting to cloud databases because of the several advantages that are offered. Some of the advantages of working with cloud databases are:

  • With the help of cloud databases, companies can become more agile and innovative. This is because cloud databases allow companies to set up, validate and test new projects very easily and quickly without incurring a lot of costs.
  • Cloud databases reduce the overall costs of maintaining and storing large amounts of data. 
  • The ability to work with cloud databases enables companies to focus on other aspects of the business rather than just working on managing the data in the right form and to ensure it stays secure.
  • Cloud databases offer many security features and have in place procedures that reduce chances of error as well as theft of data. This reduces the risk element associated with using and accessing data.

Considerations for Cloud Databases

Whenever a company moves to a cloud database to start working on it, there are several factors that need to be considered. Some of these are:

  • The architecture of the cloud database and its elements, including their validation.
  • Networking and connectivity to ensure high-speed and reliable access to data as and when required.
  • Ease of availability and access 
  • Disaster recovery mechanisms
  • Security features
  • Access management protocols
  • Cost of the services
  • Migration and expandability
  • Ease of deployment

Top Cloud Database

1. Amazon Web Services

Amazon offers a wide array of cloud database services, which includes NoSQL as well as relational databases. Amazon RDS – Relational Database Service runs on either Oracle, SQL, or MySQL server instances whereas Amazon SimpleDB is primarily a schema-less database that is meant to handle smaller workloads. Amazon DynamoDB falls on the NoSQL databases, which is a Solid State Drive – SSD - that is capable of automatically replicating workloads across three different availability zones. According to AWS CTO Werner Vogels, DynamoDB is the fastest growing database service in the history of AWS. Furthermore, Amazon offers supplementary data-management services such as Redshift – a data warehouse and Data Pipeline – a data integrating service for easier data management.

2. SAP
