As a recent technology, containers have emerged as a tool that can help your business become more agile in your software development lifecycle. Containers have many benefits that can give you a competitive advantage compared with more traditional software delivery methods.
In this post, I explain what containers are, share the key benefits of containers for software development, and discuss why you might consider adding them to your DevOps processes.
A container is a lightweight, portable computing environment that includes all the necessary files to run independently.
Containerization is the process of making an application runnable as a container. Once the application can run as a container, it runs the same regardless of the infrastructure used to execute the container. Containers are loaded with container images that run a specific application inside the container. If you want to build a modern application, from setting up a database, to loading different operating systems, to accessing a deep learning platform, you're going to need containerization.
Containerization has been widely adopted in recent years, partly due to the availability of cloud technologies. Cloud technologies let you scale and replicate containers, and they lower the barrier to entry.
Containerization can be a useful tool for you to enhance the software development lifecycle. The benefits include:
1. Containers complement your DevOps process
In our introduction to DevOps post(link is external), we discussed how DevOps as a concept is about removing barriers that get in the way of software delivery.
DevOps refines every process between the developer and the customer, and encourages faster feedback loops, experimentation, and learning. DevOps is a practice that focuses on agility and automation.
Containerization complements DevOps because software can be deployed and tested faster, improving feedback loops. Containerization is also a major factor in the popularity of microservices, a software architecture that improves flexibility and agility. You can use containerization to speed up the time it takes to develop new features and get feedback. Improving the feedback loop for your product leads to a better product and happier customers.
2. Containers are scalable and allocate resources efficiently
Platform as a Service (PaaS) solutions and container orchestration tools like Kubernetes let developers operate containers at scale. Container orchestrators can scale individual components in software applications up and down depending on demand and load. This leads to cost savings as components only run for as long as they’re needed. Scaling also improves reliability as container orchestrators can allocate sufficient resources to high-demand parts of the application.
Scaling and cost savings are important factors when deciding to migrate to containerization. Many cloud providers have a cost calculator for cloud resources that you can use if you want your department to make the switch to containers.
3. Containers are portable: build once, run anywhere
Because containers are portable, they can run anywhere on any infrastructure, such as in the cloud, on a VM, or bare metal.
The Open Container Initiative (OCI)(link is external) designs open standards for containers, ensuring any OCI compliant containers run the same way on any infrastructure.
To run applications, containers are loaded with container images. A container image is a static file that contains executable code to run a process on IT infrastructure. There are container images for different use cases such as databases, web servers, operating systems, and more. Container image repositories are public access points for container images, which makes them available to developers who can load a container with these images.
If you want to use a container for your application, you can be sure that any OCI image you use will work on your infrastructure, even if your infrastructure changes.
Conclusion
Containers are standalone computing environments, and containerization converts an application into a runnable container. Containerization gives the development process flexibility and agility, which helps DevOps processes. Containers are highly portable, and OCI compliant containers can be built once and run anywhere. With PaaS solutions and container orchestration tools like Kubernetes, containers are scalable to allocate resources efficiently.
Containerization is an ever-changing field of research. The popularity of specific tools may shift and change, but Octopus Deploy(link is external)is container and cloud-agnostic. It works with a range of container registries, PaaS providers, Docker, and Kubernetes to help make your complex deployments easier.
