Containers have become one of the key technologies associated with DevOps in the past few years. This is in a bid to improve on static environments, inconsistent deployments and cultural hurdles. Using containers in DevOps has helped teams realize agility and fast delivery of software.
What are containers?
Containers are lightweight and portable packages of software in which the application code is bundled together to run in any environment. This way, the software can run from a private cloud, public cloud or a personal laptop.
Containers eliminate the conflict between different environments and the worry about platform compatibility.
Below are some benefits of using containers in your DevOps setup.
- Great scalability.
- Containers make it easy to scale your application based on the requirements. You can create multiple identical containers of the same application and use container orchestrators to do smart scaling.
- Improved production deployment.
- Due to their consistency and release versioning feature, it is easy to roll back containerized applications when the need arises. The continuous delivery process in DevOps enables teams to deploy code changes to production environments as soon as they are ready. This process enables DevOps to have a faster time to market and frequent feedback loops.
- Greater modularity and security.
- Containers can be split into modules and can be scanned regularly to easily spot vulnerabilities and errors at an early stage.
- Improved flexibility.
- Containerized applications can move freely among physical hosts, virtual hosts and cloud environments hence increasing flexibility and minimizing vendor lock-ins.
- Improved container utilization.
- Resources in containers can be optimized through the use of specialized software such as Kubernetes which automates deployment, scaling and container management. By using a template DevOps engineers can specify the minimum and maximum CPU and memory resources that a container requires at a given time thereby avoiding over-utilization and wastage of resources.
Some use cases of containers in DevOps include;
- Enable easier deployment of repetitive tasks and jobs.
- Provide support for continuous integration and continuous deployment.
- Provide support for microservice architecture.
- Used to lift and shift existing applications into modern cloud technologies.
The use of containers will boost your DevOps journey a ton. With the correct approach and partner, you will be able to realize agility, efficiency and optimum resource utilization.
