Kubernetes Hosting

Kubernetes hosting at servinga

Kubernetes is an open-source orchestration system that provides a platform for the automated deployment, scaling, and operation of application containers through clusters of hosts. It enables complete life-cycle management of containerized applications and services with methods that provide predictability, scalability, and high availability. Kubernetes was originally designed by Google and released in 2014. Today, Kubernetes is managed by the Cloud Native Computing Foundation.

As a Kubernetes user, you can choose how your applications should run and how they can interact with other applications or the outside world. You can scale your services up or down, perform smooth updates, and control traffic between different versions of your applications to test features or undo problematic deployments. Kubernetes provides interfaces and composable platform primitives to help you define and manage your applications with great flexibility, performance and reliability. Kubernetes hosting at servinga offers everything you need to deploy containerized applications.

The name Kubernetes comes from the Greek and means helmsman or pilot, and is the origin of the terms governor and cybernetic. Kubernetes is often simply abbreviated as K8s. The abbreviation was created by replacing the 8 letters “ubernated” with an “8”.

What advantages does Kubernetes hosting at servinga offer you?

APIs

To put it simply, Kubernetes hosting at servinga provides you with the tools required to build and deploy reliable and scalable distributed applications. In modern architectures, a large number of services are provided over the network via APIs. These are delivered through distribution systems that run on multiple servers and configurations at different locations, and coordinate all their actions through network communication.

Low maintenance

If you want to update an application the traditional way, you must either log in to a VM or an existing container and load the latest software binaries of your application, shut down, and restart the server. If errors occur during multiple updates, you have no record of how many updates you have deployed and when.

DevOps

Kubernetes enables you to develop distributed systems that conform to the principles of immutable infrastructure. The immutable infrastructure creates an artifact that does not change as users change. Traditional methods have relied on introducing changes to existing objects upon incremental updates. Under such approach, the current state of the infrastructure cannot be represented as a single artifact, but as a collection of incremental updates and changes to that artifact itself.

Audit-proof

If you want to upgrade your application in the immutable infrastructure of Kubernetes Hosting, just create a new container image with a new tag. As you deploy it, the old container with the old image version is deleted. In doing so, you always have an artifact record of what your actions, and you could easily return to the previous image should there be an error in your new container image.

Kubernetes hosting at servinga delivers increased efficiency

With Kubernetes hosting, applications can be stored on the same computers without interfering with each other. This means that tasks from multiple users can be tightly packed on fewer machines. This advantage of Kubernetes hosting, in turn, increases efficiency and lowers hardware costs by reducing the number of machines used.

Kubernetes Hosting simplifies the construction of micro-service architectures

When building micro-service architectures, multiple teams each work on a single service that is used by other teams for their service implementation. The summary of all these services finally provides the implementation of the entire product interface. Kubernetes offers numerous abstractions and APIs to make this possible. Pods or groups of containers can combine container images developed by different teams into a single triggerable unit. Kubernetes hosting offers load balancing, naming and discovery to isolate one micro-service from another. Kubernetes hosting namespaces provide isolation and access control, so that microservice can control degree of mutual interaction. Decoupling the application container image and the machine allows different micro-services in Kubernetes hosting to collocate on the same machine without disturbing each other, thus reducing the overhead and cost of micro-service architectures.

Declarative configuration

Everything in Kubernetes is a declarative configuration object that represents the desired state of the system. Kubernetes hosting is an alternative to the traditional imperative configuration, where the state of the system is defined by the execution of a series of commands. An example thereof would be the execution of three software replicas. Using the imperative configuration approach, the statement would “Run A, Run B, Run C”. In a declarative configuration, however, the corresponding statement is simply “replicate = 3”. The declarative configuration of Kubernetes Hosting allows to accurately describe the state of the system and is far less prone to errors. Furthermore, traditional development tools such as source code control, unit testing, and others can be used with declarative configurations, which is not possible with imperative configurations. That makes rollbacks with Kubernetes hosting a straightforward operation. In essence, imperative systems describe how to get from point A to point B, but seldom provide return instructions.

Simple scaling with Kubernetes hosting

 

As the product grows, you need to scale your software. Kubernetes hosting facilitates scaling by means of decoupled architectures. In a decoupled architecture, each component is separated from other components by defined APIs and service load balancers. APIs provide a buffer between the implementor and the consumer, and load balancers provide a buffer between the running instances of each service. Uncoupling components through Load Balancer on Kubernetes Hosting makes it easier to scale the programs making up your service, as the size of the program can be increased without having to adjust or reconfigure other layers of your service.

Abstraction of infrastructure at Kubernetes Hosting

 

Kubernetes separates developers from certain machines. In the context of the Cloud, Kubernetes hosting provides a high level of portability, as developers use a higher-level API that is implemented with respect to the specific cloud infrastructure APIs. In this way, developers can transfer their applications between different environments, sending the declarative configuration to the new cluster. Kubernetes offers a number of plugins – available to Kubernetes hosting customers – that can abstract you from a particular Cloud. For example, Kubernetes can create load balancers on all major public clouds as well as on various private and physical infrastructures.

Scaling of applications and clusters with Kubernetes hosting

 

Scaling is simple due to the immutable, declarative nature of Kubernetes. Because containers are immutable, the number of replicas is simply a number in the declarative configuration that can be changed as needed. Of course, you can also set up automatic scaling on Kubernetes hosting, which will take care of everything for you. However, automatic scaling assumes that enough resources are available. Otherwise, you would need to extend the cluster yourself. Kubernetes also makes this task easier, as each machine in the cluster is identical to every other machine, and the applications themselves are decoupled from the machine by containers. Adding additional resources is simply creating a new machine with the required binaries.

Self-healing systems

 

Another advantage of Kubernetes hosting are self-healing systems. When Kubernetes receives a desired state configuration, it does not simply take actions to adjust the current state to the desired state at a particular time. Kubernetes also ensures that the condition stays as desired over time. If you specify a desired status of three replicas of a specific application on Kubernetes Hosting, Kubernetes will not only create three replicas, but will also ensure that there are exactly three replicas. If you destroy one manually, Kubernetes creates a new one to achieve the desired state.
