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.

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.

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.

• Whoa! Thats a big number, arent you
  proud?

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.

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.

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.
