Cloud Native Databases on Docker and Kubernetes

What is Cloud-Native Database?

A Cloud-Native database is a sort of database service which is used to build, deployed and delivered through cloud platforms. It is mostly a Cloud platform as a service which provides models that allow the organization, end-user and their respective applications to store and manage and retrieve data from the cloud. Cloud Database which delivers a scalable, reliable database solution. Clients have a service level for their cloud environment. It is deployed across a non-virtualized environment, giving the databases accessible to the full capacity of the underlying hardware.

Why is Cloud-Native Databases Important?

Cloud-native databases have become increasingly important in today's digital landscape. As businesses continue to embrace cloud computing, the need for databases that are specifically designed for the cloud environment has become evident. These databases offer a range of benefits that traditional databases cannot match.

1. Enhanced Security

Cloud-native database may seem like a very distant and intangible place to store valuable information. It is more secure than a User think. With the help of proper anti-virus and firewalls and some rules, we can secure our data. Also, staying with the latest software technology guarantees that cloud computing can provide higher quality data protection for business handling sensitive information.

2. Increased Storage Capacity

It is one of the most useful aspects of the cloud that it can store a large amount of data without the need for multiple USB drives.

3. Effective Collaboration

In this service, we can access our information from anywhere. It creates the perfect tool for collaboration, especially with colleagues all over the country. This aspect makes it easy for all team members to collaborate without the danger of lost or duplicate work.

4. Cost Effective

It is cost effective because a one-time payment for unlimited storage in the cloud is a lot more cost effective than having to buy or repair multiple hard drives continually. If we purchase relatively cheap Hard drives, they are easily lost or damaged, thus, making them expensive to maintain in the long-term. So to over this Cloud Storage allows buying as much as a little storage you require relative for workflow.

5. Redundancy

Cloud computing provides duplicate copies and systems that can be used in the case of a failure. These duplicate copies are made accessible through having data replicated on multiple computers within the same database. These service helps users that their information always available to them even when things take an unexpected turn.

5. Easy Database Management

The automation and scalability features of cloud native databases make managing and updating them a hassle-free experience. With streamlined processes and the ability to easily scale resources, database management becomes more efficient and less time-consuming.

6. Accessibility

Unlike traditional databases that are limited to deployment systems, cloud native databases utilize distributed database technology, making them easily accessible from anywhere. This enables seamless collaboration and data sharing among teams and locations.

7. Elasticity

Scaling up and down is equally important for a cloud native database. It should have the ability to increase or decrease its capacity based on workload demands. This ensures that users only pay for the resources they actually need, which is a significant advantage of cloud technology.

How to adopt Cloud Native Databases?

There are many different cloud database providers are working which provide database as a service, which is further divided into three major categories, there are Relational, Non-Relational and Running Virtual Machine Loaded with local database software like SQL.There are lots of companies offering database as a service like Amazon RDS, Microsoft SQL Azure, Google App Engine Data store, and Amazon SimpleDB. Each Service Provider is different from others depending on the quality and sort of services being provided. Specific parameters can be used to select the best service that will suit the company.

Step-1: Choosing best DBaaS

By the selecting of DBaaS which is depends not only on the services which are provided by the company. But it also depends on the requirement of the company as well. Specific parameters can be taken as a guide to choosing the best DBaaS.

Step-2: Data Sizing

In each DBaaS provider has a different capacity of storing data on the database. The data sizing is critical that will go sure about the sizes of data that it will be stored in the database.E.g - Amazon RDS which allows the user to stored up to 1TB of data in the one database, on the other hand, SQL Azure allows only 50GB of data for one database.

Step-3: Transaction Capabilities

The transaction capabilities are the dominant feature of the cloud database as the completion of the transaction is essential for the user. The user must be aware that the deal has been successful or not.

Step-4: Configuration

Many databases can become easily configurable by the user as most of the configuration is done by the service provider. In this way, there are decidedly fewer options available left to the administrator of the databases, and admin can efficiently manage the database without more efforts.

Step-5: Data Integrity, Security and Storage Location

Security has been the major threats to the data which is stored in the cloud storage. The guard also depends on the encryption methods used and the storage locations of the data. The data is stored in different areas in data centers.

Do Cloud Native Databases need Kubernetes?

The advent of cloud computing has brought about a paradigm shift in data management practices. As organizations increasingly migrate their database workloads to the cloud, they face the challenge of effectively managing stateful data in this dynamic environment. Data gravity poses a significant hurdle, as regulatory and legal constraints often make data migration complex and costly. This underscores the growing emphasis on maintaining a close proximity between applications and their associated data.

The introduction of containerized applications powered by Kubernetes further complicates the data management landscape. While Kubernetes was initially designed to orchestrate stateless workloads, the demand for its support in managing databases has grown exponentially. This shift towards running databases on Kubernetes stems from the desire to streamline development and operational efficiency by consolidating the entire infrastructure stack onto a single platform. However, this integration introduces additional requirements that cloud-native databases must fulfill to operate seamlessly within the Kubernetes ecosystem.

1. Containerisation

First and foremost, it is crucial to understand that running a database in containers requires a certain level of effort. It may not be as straightforward as it initially appears. Certain steps, such as externalizing storage, optimizing memory and other computing resources, and ensuring accessibility of application logs and metrics for monitoring and log aggregation, are all vital in this process.

2. Storage

Furthermore, it is essential to align the storage requirements of the database with the constructs provided by Kubernetes. Each database node should initiate a persistent volume claim to allow Kubernetes to allocate a storage volume that meets the necessary capacity and I/O characteristics. Typically, databases are deployed using Kubernetes Stateful Sets, which effectively manage the mapping of storage volumes to pods and maintain a consistent and predictable identity.

3. Automated Operations

Lastly, it is essential to have the necessary tools to efficiently manage and automate database operations, including installation and maintenance. This is commonly achieved through the utilization of the Kubernetes operator pattern. Operators act as control loops that monitor the state of Kubernetes resources and take appropriate actions to ensure the desired state is achieved. They are similar to Kubernetes built-in controllers but with the added advantage of understanding domain-specific state, allowing them to assist Kubernetes in making more informed decisions.
