DevOps is nothing but a combination of the development and operations teams in a company. It encompasses a set of practices for designing Agile software. DevOps is a methodology that is simplified such that Project Managers and their teams have a variety of options to choose from.
Additionally, Amazon defines the concept of DevOps as an amalgamation of various cultural practices, tools and philosophies that help enhance an organisation’s ability to deliver applications and services at optimum velocity.
It especially helps to evolve and improve their products at a quicker pace than their counterparts in the industry who utilise traditional processes for developing their software and managing their infrastructure.
Moreover, DevOps is intended to foster collaboration between the development and operations teams in an organisation to make the experience of delivering the software faster, more accurate and responsive.
AWS DevOps combines the agility and scalability of AWS infrastructure with the efficiency and collaboration of DevOps practices. It emphasises the automation of processes, enabling developers and operations teams to work closely together throughout the Software Development Lifecycle (SDLC). This alignment ensures faster time to market, improved quality, and enhanced customer satisfaction.
Additionally, it is important to note that Cloud Computing has gained immense popularity over time and users consequently face over a dozen options of various cloud providers, with the likes of Microsoft Azure, Amazon’s cloud provider, Amazon Web Services (AWS). These providers offer the public all the services and features that you would typically receive in a resident data centre.
Now, AWS DevOps can be understood as Amazon’s implementation of the DevOps philosophy through its cloud platform and other dedicated tools and services. The service basically offers a curated set of services designed to be flexible and help companies build and deliver products with more speed and reliability.
Furthermore, AWS DevOps intends to offer the application developer teams the means to implement the process of continuous integration and continuous delivery(CI/CD). This process basically facilitates the secure storage of the application’s source code while simultaneously building, testing and eventually deploying the AWS Application . The deployment is also flexible enough to be either on-premises or to the AWS Cloud.
Cloud Computing generally comprises of three key categories:
a) Software as a Service or SaaS
b) Platform as a Service or PaaS
c) Infrastructure as a Service or IaaS
The AWS service comes under the IaaS category of cloud computing owing to its scalable infrastructure designed to enable instant computing. This infrastructure is meant to be controlled completely by the customer, with the inclusion of virtual servers and Operating Systems (OS).
