DevOps Fandamental

  To run the business processes smoothly and efficiently, there are continuous updates in the software developmental approach. DevOps is such a tool that has assured exceptional, swifter, and productive services with high-end customer satisfaction. DevOps have become a flair in the recent IT market. Consequently, the demand for engineers to develop, supervise, and deal DevOps practices is on a rise in organizations of various industries. To meet this demand and raise their own efficiency, organizations are hiring skilled DevOps engineers. In order to avail of this booming opportunity, one must be aware of what a DevOps does and the required prerequisites.

What is DevOps Basically?

DevOps (Development Operations) is a pioneer innovative development method comprising of just a few sets of processes that synchronize to integrate development teams and processes to supplement software development. DevOps is in huge demand because it brings high speed and accuracy creating a relationship between development and IT operations allowing organizations to create and modify their products at a comparatively brisk pace than available traditional software development methods. A strong alliance of divergent teams- developing, testing, and operating- is its distinguished concept. This strong collaboration of teams results in identifying and solving errors quickly. In the DevOps scenario, the codes are continuously developed, tested, integrated, deployed, and monitored to provide the standard output in less duration.

Who is a DevOps Engineer?

As a matter of fact, there is no orthodox career course for a DevOps engineer. He can be an IT professional - developer or system administrator to expand the responsibilities towards the ingenious progressive evolution of DevOps. The key responsibilities of DevOps engineer are-

*Administration of IT infrastructure,

*Choosing the right deployment models,

*Conducting the testing protocol and critical monitoring

Prerequisites of a DevOps Engineer

As a DevOps engineer has a very pivotal role to play in any organization, it is mandatory for one to be perfect in various technical and personal skills such as Coding, re-engineering of processes, and collaboration. Some of the prerequisites of a DevOps engineer are-

A) Containers are one of the most required assets for a DevOps engineer to have on his or her resume. Containers enable developers to generate applications and install them to servers from a laptop. This tool has changed the whole scenario of apps’ creation, operation, and shipment. It has become one of the most in practice advances in DevOps technology due to the ability to impart an accurate and directed environment to build within.

B) Grasp of programming languages It is mandatory for the DevOps engineer to have a basic knowledge of certain basic programming languages such as Java, Perl, and Python as it ensures the DevOps engineer to handle the development team well so as to enable the uniform trouble-free flow of application installation, configuration and validation. A great DevOps engineer should also be a scripting guru as he must be capable of writing code to automate repeatable processes.

C) Comprehending Tools and Technologies Various specific operations of development, testing, integration, observing, formation, and others depend on various DevOps tools. The DevOps engineer should have a thorough comprehension of popular tools such as Ansible, Chef, Docker, ELK Stack GIT, Jenkins, Puppet, Selenium, and Splunk. He or she should be eager to learn new technologies, offer novel solutions and recommendations, and be adaptive to face challenges.

D) DevOps Training and Certification One of the quite crucial and important qualifications of the DevOps engineer is DevOps training and certification. It offers to provide an effective route to learn various processes of DevOps - basics, DevOps tools, lifecycle, workflow, and other processes. Hyderabad is the current hub in India for DevOps training. Certification as DevOps professional is a huge advantage as it marks up-gradation of skills as well as the enhanced capacity to improve business scope. One gets valuable hands-on experience by handling real-time projects works and gets exposure to the live environment of projects in training.

E) Knowledge of Automation Tools It is quite imperative to have a comprehensive grasp of automation tools and techniques as nowadays, everything is automated and a DevOps engineer must be skilled at handling automation processes at different levels of development, testing and operation .A distinct and comprehensive knowledge of infrastructure automation such as creation and configuration of apps and systems, app deployments, etc.  encourages the ability to maintain better processes. He or she must have comprehensive knowledge of Jenkins, Bamboo, Hudson Thought Works, and other tools to move ahead.

F) Testing A DevOps engineer is responsible for the proper administration of testing procedures at all levels. So, it is imperative for him or her to have good knowledge of testing tools and other applications. It also makes him capable of identifying the bugs at any stage quite easily - so debugging and resolutions become easy.

G) Excellent Collaboration Two personal skills which make a DevOps engineer quite an efficient one is- excellent collaboration and communication skills as DevOps targets on collaborative support services. Excellent communication skills help in avoiding any misinterpretation and it helps in agile functioning. Being adaptable allows DevOps engineers to pick up new jobs briskly and share their skills in various areas when required. A good DevOps engineer must be a problem solver, both in the cloud and in real life.

H) Grasp of Networking the DevOps engineer should have a grasp of networking too as efficient networking enables the final developments, applications, or services to be promoted to the client's environment as per the desired design and planning.

I) Logical Attitude A good rational, logical and comprehensive outlook is also, a trait required for being a successful DevOps engineer as sometimes it will be his or her sole responsibility to take immediate decisions for smooth and successful functioning in the organization.

Excellent leadership qualities marshaled with super communicational and professional expertise attribute to the success of a DevOps engineer.

J) Passion It is the ultimate key to unwind any trouble in being a success as a candidate who is passionate about his or her work, will definitely hit the bull’s eye. It is the chief prerequisite that can never be overlooked, even in the world of digital clouds and coding.

  Terraform is an infrastructure as code tool that lets you build, change, and version cloud and on-prem resources safely and efficiently. HashiCorp Terraform is an infrastructure as code tool that lets you define both cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share. You can then use a consistent workflow to provision and manage all of your infrastructure throughout its lifecycle. Terraform can manage low-level components like compute, storage, and networking resources, as well as high-level components like DNS entries and SaaS features. How does Terraform work? Terraform creates and manages resources on cloud platforms and other services through their application programming interfaces (APIs). Providers enable Terraform to work with virtually any platform or service with an accessible API. HashiCorp and the Terraform community have already written  thousands of providers  to manage many different types of resources and services.

Kubernetes

  Using containers to host applications and other processes has gone mainstream. As more and more workload is moved into containers, management systems are needed to handle the demands of containerized applications at scale. One of the most popular options for managing  container-based workload is Kubernetes . Kubernetes combines container management automation with an extensible API to create a cloud-native application management powerhouse. At its core, Kubernetes manages the placement of pods, which can consist of one or more containers, on a Kubernetes cluster node. Additionally, if one of these pods crashes, Kubernetes can create a new instance of it. If a cluster node is removed, Kubernetes can move any affected workload to a different node in the cluster. On top of that, Kubernetes pods can be scaled to provide more or less throughput to meet scale demands and these scale operations can be triggered manually or automatically using Kuberentes horizontal pod auto-scaling. Finally,
