What are Containers and Containerized Applications?
The packaging of software programs with all its dependencies i.e. frameworks, libraries, binaries, configurations files into a single, lightweight, portable executable unit. Containerized Applications makes use of Containers to package and run consistently on different computing environments, hosts and cloud platforms with the help of Container engine & runtimes such as Docker, Containerd Podman, etc. Containers are primary component of modern cloud native applications.
What are the benefits of Containerized Applications?
Containers provide several benefits to Developers to build, deploy and scale modern applications, it includes:
- a) Portability: Software Developers write code once which can then be containerized to run consistently on different environments, local workstations, on-premises, cloud, different OS
- b) Scalability: Containers are lightweight software packages and run very fast and efficiently. Multiple containers can be replicated quickly to provide scalability for various workloads
- c) Isolation: Containers are isolated from other containers, thus failure in one application instance due to bugs do not affect other replicated containerized instances
- d) Fault Tolerance: Isolation provided by containers enable a service to be highly fault-tolerant which is a key necessity of businesses running online where downtime can result in high financial loses
What are the use-cases of Containerized Applications
Containerized Applications have several use-cases such as:
- a) Micro-services: Breaking large applications into smaller, manageable, and independent services where each service can deployed and updated independently
- b) DevOps CI/CD : Containers runs consistently in different environments such as development, testing, production on various compute instances enabling Continuous Integration & Continuous Deployment
- c) Cloud Migration: Cloud migration, or the lift-and-shift approach, is a software strategy that involves encapsulating legacy applications in containers and deploying them in a cloud computing environment without rewriting the entire software code.
- d) IoT & Edge Computing: IoT Applications can be deployed using light-weight, efficient application containers on resource-constrained edge devices.
Containers and Cloud Native Applications
Cloud-native is an approach to building, deploying, and managing modern applications designed specifically for cloud computing environments. Containers, Container Orchestrating tools such as Kubernetes, ECS, DevOps practices help in developing and deploying highly scalable, resilient and agile systems and services which can be updated frequently, without services disruptions. This is how modern large scale, data-intensive services that we use daily operates
Difference between Containerized and Serverless Applications.
Containerization provides a secure, reliable, and lightweight runtime environment for applications that runs consistently in different environments and hosts. Serverless Technology on the other hand, works in which developers develop and deploy code and the cloud providers manages entire infrastructure on which the applications runs. Serverless and Containerized Applications are used together frequently in which certain services and capabilities are provided out-of-box by cloud providers.
