3. Container • A container is a type of OS (Operating System) virtualization. It provides an efficient solution for ensuring that a software works reliably when it is moved from a computing environment to another. A container provides, in a single package, a complete runtime environment which has an application and its dependencies along with libraries and other binaries as well as the configuration files that are required to run it. Containerized environments enable the virtualization of multiple application runtime environments on a single OS instance (kernel). • A container is portable and lightweight and can run a small microservice to a software process to a large application. Multiple containers are deployed in the form of one or numerous container clusters in large application deployments. These clusters are usually managed by container orchestrators. The capability to run multiple containers on a single operating system kernel is beneficial in the creation of cloud-based microservices architecture. • To digress, cloud technology is used in cloud hosting, which is a type of web hosting service that makes websites accessible. This service is provided by web hosting companies and the best service providers are usually referred to as the “Top Cloud Hosting Company”, the “Best Website Hosting Company” etc. • Containers are a popular option for running microservices applications. A containerized microservice has its own RAM, storage, CPU, file system as well as access to certain system resources.

4. Benefits of Containers There are many benefits of containers. The main benefits of containers are mentioned below. • Augmented portability as well as consistency across various OS- Containerized apps and microservices can be deployed easily on a wide range of operating systems and platforms. • Reduced overhead- Since containers do not need operating system images, these require a lesser number of system resources when compared to virtual machines. This results in the better utilization of a server and does away with any additional licensing cost that has to do with an OS. • Provide an easier adoption of microservices architecture- Containers are the prime choice with regard to adopting microservices architecture. This stems from the fact that these are less expensive when compared to other solutions. • Enable faster development of applications- The organization of development of applications is swifter and easier with the aid of a network of containerized microservices that run independently. • Require less storage space- Containers are smaller than virtual machines and require less space for storage. • Faster startup- By bypassing the need for a virtual machine, containers startup within seconds. This provides an enhanced app user experience.

5. Containers’ Uses The most common ways in which containers are used by companies are mentioned below. • For the migration of existing applications into cloud architecture. • For refactoring existing containers’ applications. • For developing new container-native applications. • For providing enhanced support to microservices architectures. • For providing DevOps support to ensure continuous integration and deployment (CI/CD). • For ensuring easier deployment of jobs and tasks that are repetitive.

7. Microservices • A microservices architecture provides the strategy for developing applications by dividing monolithic applications into suites of loosely-integrated and independent services which are referred to as microservices. Microservices function in collaboration for the creation of a pluggable application architecture, wherein individual services interact with each other through APIs (Application Programming Interface). • Microservices applications offer more flexibility and agility in comparison to monolithic applications. Since the connections among individual microservices are loose as well as pluggable, an application architecture is attained which facilitates maintenance, upgrades and development.

8. Benefits of Microservices The main benefits of microservices are as follows: • Enhanced stability as well as robustness of the system. • Reduction in interdependencies. • Better organization of development processes. • Faster time to market.

9. Benefits of Containerized Microservices The major benefits of containerized microservices are mentioned below, in no particular order. • Enhanced performance. • Lower infrastructure footprint. • More robustness compared to traditional monolithic applications. • Provide the possibility to replicate microservices across smaller virtual machines’ clusters. • Aid in eliminating maintenance downtime. • Enable developers to work on their specific tasks without getting involved in the entire application. • Provide the freedom to code services in the languages that suit the developers. • Provide high portability in CI (Continuous Integration) and CD (Continuous Delivery), which aid in enhancing productivity. • Make it difficult for any security breach to spread from a container to another container.
