Kubernetes, also known as K8s or Kube, is an open-source container orchestration technology that schedules containerized applications’ deployment, administration, and scaling. Google created this platform before making it open-source in 2014. Nevertheless, Kubernetes has become the de facto container orchestration standard. It is the flagship project of the CNCF (Cloud Native Computing Foundation), supported by significant entities such as Google, AWS, Microsoft, IBM, Intel, Cisco, and Red Hat. Kubernetes simplifies the deployment and operation of applications in a microservices architecture. Kubernetes is presently one of the most rapidly developing open-source projects in history. It currently has over 2300 contributors and is extensively used by enterprises large and small, including half of the Fortune 100.
KEY FEATURES OF KUBERNETES
- Automated Scheduling
- Self-Healing Capabilities
- Automated rollouts & rollback
- Horizontal Scaling & Load Balancing
- Offers environment consistency for development, testing, and production
- Infrastructure is loosely coupled to each component and can act as a separate unit
- Provides a higher density of resource utilization
- Offers enterprise-ready features
- Application-centric management
- Auto-scalable infrastructure
- You can create predictable infrastructure
WHY USE KUBERNETES?
There are several reasons why you should consider utilizing Kubernetes. Compared to other platforms on the market, the platform has several benefits. Among the advantages of Kubernetes are the following:
- Business Productivity:
One of the most beneficial aspects of adopting Kubernetes is that the platform enables you to improve company productivity. Increase productivity and drive outcomes since it removes the need for most manual processes. Kubernetes automates several procedures, increasing the efficiency of your business.
- Cost optimization:
Kubernetes can help enterprises save costs on ecosystem management while maintaining scalability across multiple environments through dynamic and intelligent container administration. Because of native autoscaling (HPA, VPA) logic and integrations with crucial cloud suppliers capable of dynamizing resources, resource allocation is automatically adjusted to the actual application demands. At the same time, low-level manual activities on the infrastructure are considerably minimized.
The stability of an application will determine whether it is performant or non-performant. Fortunately, for Kubernetes users, this will be the least of their concerns because the platform provides unparalleled stability. As a result, you can always rely on Kubernetes’ reliability, no matter how feature-rich or sophisticated your application is.
Kubernetes is compatible with almost any container runtime. (A runtime is the software that executes containers. There are several alternatives on the market now.) Furthermore, Kubernetes may function with nearly any form of the underlying infrastructure, whether a public cloud, a private cloud, or an on-premises server, as long as the host operating system is Linux or Windows (2016 or newer).
- Multi-cloud capability:
Kubernetes makes it simple to achieve the multi-cloud promise. Because it works in any environment, it can effectively scale environments from one cloud provider to another – and even from on-premises to the cloud – without sacrificing functionality or performance. This mobility eliminates vendor lock-in, allowing you to match workloads with the optimum cloud service for your use case. As a result, 92% of firms are developing a multi-cloud strategy to accelerate innovation, boost resiliency, and control expenses.
Kubernetes is free and open-source software that is supported by a large community. This implies that you may utilize Kubernetes as you wish. There is no need to purchase a software license, and you may modify the code of Kubernetes to suit your needs better. CNCF is in charge of managing the platform and ensuring that everything runs well. Various corporate sponsors support the platform, but nobody owns it.
Kubernetes does not just start thousands of containers when we give it instructions. It also ensures that the desired condition is maintained at all times. And it’s quite good at doing so. If a container fails, it can replicate a working one. If a server is down, it may detect it and rebuild the lost containers on a new operating server.
- Automated rollouts and rollbacks:
Kubernetes allows you to specify the ideal state for your deployed containers and can transform the actual state to the desired state at a regulated rate. For example, you can use Kubernetes to automate the creation of new containers for your deployment, remove current containers, and adapt all their resources to the new container.
WHAT IS AN ADMINER?
Adminer, formerly known as phpMinAdmin, is a database content management tool. It contains a single file ready to be deployed to the target server. Adminer supports MySql, MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, and ElasticSearch natively. Plugin for MongoDB and other databases.
Regarding lightweight, user-friendly, high-performance MySQL database management tools, Adminer gas has widespread appeal and offers several improvements over phpMyAdmin. Jakub Vrana created this administration tool in 2007 as an alternative to phpMyAdmin so that users can download and install a single, lightweight PHP file on the application’s database.
Adminer is free to use and can be written in PHP as it is an open-source management tool. This web-based database management system is unique because it has an exemplary user interface design for a seamless user experience and robust security features to keep the data safe from any attacks or malicious hacking attempts. This database management tool is easy to set up and requires simple requirements such as Ubuntu and LAMP. In addition, users can find comprehensive documentation regarding development and deployment. Hence, users can find the source files of this web-based database management system on GitHub.
KEY FEATURES OF ADMINER
The following are some simple yet crucial features of this database management tool:
- It provides various functions, such as selecting a database, editing tables, inserting/editing data in tables, and sorting/searching data in multiple columns.
- Databases supported include MySQL, PostgreSQL, SQLite, MS SQL, Oracle, and SimpleDB, among others.
- It’s available in 43 languages, including English, Arabic, Persian, Polish, and Dutch.
- Views, triggers, stored procedures, user rights, and other database objects can be changed.
Adminer also includes security methods to protect against SQL injection, session theft, cross-site scripting (XSS), and other threats.
