Microservices is a cutting-edge software development technique in which an application is organized as a collection of loosely connected services. Each service should employ a single business feature and be self-contained.
Microservice architecture aims to eliminate the challenges, failures, and breakdowns that larger programs face, while also increasing the modularity of the system. It is well-suited to the creation of enterprise software.
Containers, like Microservices, have grown in favor as an essential component of modern architecture. Microservices and containers are both dependable and scalable and provide a wonderful concept for isolating the critical element of your web services. Microservices and containers are nearly inextricably linked and serve as a stimulus for one another.
Kubernetes, the renowned container management platform, is the best solution for adhering to all of the above requirements of a Microservices framework.
Setup and management of a Microservices architecture can be greatly facilitated by Kubernetes and the assistance of a few other widely used tools and technologies.
The service concept in Kubernetes allows for a microservices architecture. It enables developers to take away a group of Pods’ functionality and present it to other developers via a well-defined API. Here, we will look to develop an understanding of Kubernetes, why is Kubernetes important for microservices, and the main benefits of choosing it for microservices.
What is Kubernetes?
Kubernetes (also referred to as k8s) is a Google-developed open-source platform that supports containerized applications across numerous servers, including basic frameworks for deployment, maintenance, and scalability.
Kubernetes is a cluster management software created by the Cloud Native Computing Foundation (CNCF) in the Go programming language. It was launched in 2014 and hasn’t looked back since. As per Gartner’s research, containerized apps would be used by more than 75% of enterprises globally by 2022.
Kubernetes can be used in a public cloud or on a private network. Cloud computing service providers such as Microsoft Azure, AWS, and Google Cloud Platform offer managed Kubernetes services that let users quickly launch and administer K8s apps.
The fundamental benefit of Kubernetes (also known as K8s) is that it improves infrastructure utilization by allowing different processes to share computer resources efficiently.
Kubernetes is the king of allocating computing resources dynamically to meet demand. This enables businesses to avoid having to pay for computing resources that aren’t being used. K8s provide several other benefits as well that make the move to microservices much easier.
The Benefits of Choosing Kubernetes for Microservices
Your teams will gain greater autonomy and freedom when you break down your monolithic program into independent, loosely linked microservices.
They must, however, work closely together when engaging with the infrastructure on which the microservices must execute.
You’ll have to deal with issues such as:
- Estimating how much computational power each service will require;
- How these requirements fluctuate as a result of the load;
- How to divide infrastructure into microservices and cut out infrastructure segments; and
- Impose resource constraints.
Kubernetes effectively solves these issues by providing a unified framework for describing, inspecting, and reasoning about infrastructure resource distribution and use. As a result, incorporating Kubernetes into your microservice re-architecture is a smart move. The following are some of the main benefits you can get from choosing Kubernetes for microservices.
1. Time and Money Savings
You may be charged based on the amount of individual compute resources you execute in your current orchestration. There is no need to utilize all of your capabilities at the same time using Kubernetes. To minimize costs, you can automate resources based on need (for example, you might need more resources at 4 pm than you do at midnight).
Kubernetes makes it possible to automate and simplify your administrative scaling operations. Because the containers are designed to be lightweight, they may be quickly assembled. It’s simple to deconstruct your program into distinct components and functions. As a result, you can swiftly scale up to assist you in responding quickly.
What we need in these instances is a mechanism that will scale up the application as customers buy more things and scale down when the load drops. Kubernetes not only aids in the scaling of infrastructure indicators but also in resource consumption metrics and bespoke metrics to aid in the scalability of the process.
Kubernetes was created to solve challenges caused by monolithic application setups with a high number of servers and, as a result, a huge number of administrative duties. The introduction of containers has just added to the situation.
Kubernetes is a cloud-native environment designed primarily to solve these issues. Kubernetes makes it easier to manage a large number of separate servers or containers, as well as the numerous administrative responsibilities that come with it.
Kubernetes’ portability enables you to execute Kubernetes pods across many clouds, both on-premises and off, and to do so effortlessly. This implies that you can easily move your systems. This is a major time saver and will save you and your team a great deal of effort.
4. Effective Migration to Cloud
There’s no reason to be intimidated if you’re considering switching from a monolithic to a Kubernetes setup. All big organizations are using Kubernetes to migrate their apps or web services to a container-based cloud infrastructure. The cloud environment is not only reliable, but also scalable, and it may help you save money and reduce operational stress.
Re-hosting an app is simple with Kubernetes, and if you want to make some modifications, you can do it instantly and your app will continue to run well. Kubernetes gives you the freedom to make any modifications you want to the application.
Kubernetes provides a more straightforward and standard method of moving your application from on-premises to the cloud, as it reliably works across all situations on-premises and in clouds like GCP, Azure, and AWS.
Conclusion to why is Kubernetes important for Microservices
Kubernetes makes it easy for businesses to operate their programs on any public cloud provider, as well as on private and public clouds. If you’re using Kubernetes for its unique features or using it for easy app migration to optimize your ROI, then it’s the ultimate pick for your microservices architecture without any doubt.
