Why you must use Kubernetes to create financial applications

It is crucial to choose the right infrastructure when developing software. The tools you pick to work with could cause problems for your company in the future if they fail. Infrastructure as code is much easier to restart. If the frontend is created with PHP and the backend is created with JS, it is easier to manage this whole infrastructure if it is communicated via Kubernetes.

The advantage of Kubernetes is that programmers can use it anywhere. Kubernetes is an open-source container-orchestration system for automating computer application deployment, scaling, and management. In this article, we will share some of the benefits of using this technology.

Introduction

Instruments to create Docker technology were developed in the 1990s by Linux and Unix. Yet nobody but Docker thought about its hidden possibilities as the technology was implemented in 2013.

Docker is a program that allows programmers to use functions of existing Unix systems to avoid overusing resources. It means that programmers cannot use all current hardware but can take some “pieces” from hardware: cores, memory space, etc. This approach enables creating machines inside the machine.

The idea of this method is that some processes do not need all the resources of the machine. That is why the programmer creates a so-called container. The next step was the creation of these containers for the web. From that time on, people could make containers on any computer in the world, combine their resources, and remaster these machines as they needed.

Next step

Kubernetes is the last step in this story. It allows us to connect all those different containers and create one huge application. For example, there is a container with API and another container with front end, etc. Kubernetes allows all these parts to communicate and work as a single mechanism.

We also have the solution case study on how to create as many API integrations as your business needs.

The benefits of Kubernetes technology are

  • cost-efficiency
  • fast development of new ideas
  • fast scaling up of services

Pros and cons of using Kubernetes 

Pros of Kubernetes 

  • Previously, in the 2000s, there was no option except working on specific servers without the possibility of changing capacity.
  • Programmers do not need to depend on hardware. They can use the cores, RAM, and memory they need. 
  • Scaling allows increasing resources if a load is multiplying and vice versa.
  • Google and Amazon released cloud services and used Kubernetes inside their companies.
  • Google makes the technology open source to develop it.

Cons of Kubernetes 

There are situations in which Kubernetes is not the best option.

iOS codes for specific hardware, Apple, so programmers know the characteristics of this hardware.  Android codes for different hardware, so programmers reserve memory space for some functions by default. Sometimes this function does not need all the reserved resources.

Conclusion

  • Kubernetes allows teams to build and deploy “microservices” in containers. 
  • The application runs as a collection of services.
  • The services are organized around business services.
  • The software is packaged in containers; it can be released and updated rapidly without taking it offline.
  • Kubernetes allows you to automatically scale the underlying infrastructure.
  • Kubernetes allows you to deal with demand while keeping infrastructure costs to a minimum.
