Container orchestration hasn’t been around for a long. Nevertheless, their popularity has grown quickly. The build, ship, and maintenance of software have greatly improved as a result of this transformation. But what is container orchestration? And how is Kubernetes on AWS connected with it? Let’s dive in.
Container Orchestration: What is it?
Automation of operations for containerized workloads and services is container orchestration. When you need to run workloads and services, container orchestration automates the process.
Container life cycle management includes a variety of tasks. Configuring, scaling, and networking are some of these tasks. Besides, scaling can be up-scaled and down-scaled.
To simplify, the container is a way to build software. Not just building, but also you can package and deploy with containers. Although they are similar to virtual machines, they are not identical. Because containers are isolated from the OS beneath them, they have different infrastructures.
An application container contains the code of the application, as well as the components it requires to operate.
Container vs Microservices: The Differences
There are rising confusions regarding the differences between a container and microservices. Even though both are used in the journey of developing software, they are distinct. Besides, the professionals who use are different too.
Containers allow you to distribute resources logically. In addition to that, sharing technology is another thing that you can do with containers. Hence, people from the DevOps team will love to use such a tool.
On the other hand, microservices focus on the design. There are many ways in which this software design pattern can be applied to the development of software. This is something the developers want to work with.
Container and microservices are not something you use interchangeably. They should usually be used collaboratively. Generally, it is recommended to run microservices in containers. Moreover, a great way to avoid the failure of risks. Through microservices, you can distribute the application across multiple containers. With the help of scaling the software, you will be able to combine both resilience and agility.
Container Orchestration: The Benefits
Benefits are the main factors that made containers so popular. In addition to their lightweight and ephemeral nature, containers offer some great advantages. Let’s talk about those,
Containers can run in any environment. Even though logically it may seem inconsequential, this enhances productivity. By using containers, you will not have to rewrite your code for different environments. The software will operate smoothly on whatever operating system is being used. This type of code is very useful for developers since it allows for the consistent writing of codes. This type of code can be deployed to any machine, including public clouds.
Development of the Application:
In the case of development, containers take a different approach. The approach certainly seems to be effective. By speeding up the development as well as the deployment, they can ensure enhanced productivity. However, this is exclusive to microservices that are containerized.
It is also intriguing to note that this allows problems to be broken into smaller pieces. Therefore, each of the microservices can aid each part to get resolved. It is possible to deploy, update, or retire microservices independently in this case. Fun fact, you don’t need to change anything as a whole.
Utilization of Resources:
The first step to effectively using a resource is to make sure that it is utilized properly. And proper allocation of resources plays a great part in that. Containers ensure your resources are utilized properly.
Containers are lightweight. Also, they don’t last long, hence ephemeral. They are high-optimized for this reason. Therefore, they do not consume plenty of resources, but a few. One machine is capable of running them perfectly.
Container Orchestration: Some Great Options in the Market
So now you may be wondering what are the options for container orchestration. Glad you asked. There are some great options that provide exclusive benefits. Additionally, as has already been mentioned, containers can be run on any environment, such as Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure.
A brainchild from the folks at Google, Kubernetes is considered as a standard for containerization. It was an offshoot from Google’s Borg Project. Cloud-Native Computing Foundations’ flagship project was Kubernetes. Therefore, this service is backed by some of the biggest names in the industry. Google, Amazon, Microsoft, IBM, CISCO, and Intel are quite a few.
Platform-as-a-Service (PaaS) is a self-service platform that Kubernetes allows DevOps to deliver. These services create an abstraction layer between the hardware and the development team. Besides, as being a container orchestration, Kubernetes is highly portable. That means you can run this on any platform you want. Kubernetes on AWS, Kubernetes on GCP, or Kubernetes of Microsoft Azure, any way you want.
Might be a bit complicated, but Apache Mesos sure give a lot of flexibility. The software, which was created at Berkeley, supports Twitter, PayPal, and Uber. Besides, it was created before Kubernetes.
One great part of Apache Mesos is its level of scalability. Increasing the number of nodes to 10.000 without sacrificing productivity is possible. On top of that, the framework operates independently. Java, C++, and Python are all supported by Apache Mesos’s APIs. Additionally, high availability comes standard.
Now embracing the Kubernetes, Docker owns its container service too named Swarm. This tool is comparatively easier and faster than Kubernetes. However, you do lose some quality. Being less extensible and complex, you are limited to simpler tasks. But, when you need to get something done in a short period, this is what you can rely on.
Container orchestration has come a long way, thanks to modern technological advancements. As innovations emerged, services like these are getting better and better. However, there are some downsides as well. The good news is that the drawbacks are getting smaller and smaller with the progression of time.
Your productivity will be greatly enhanced with the help of container orchestration. The Swarm from Docker can limit you to some extent, but Kubernetes or Mesos will give you greater control. But as mention swarm is simple and the other ones are complex. Hence, you have a choice.
