DevOps Engineer Job Description: Roles and Responsibilities

Q: 1. What are data structures in programming?

Data structures are the way we arrange data in a program. The two most important data structures are arrays and linked lists. Arrays are the most familiar data structure, and it is the easiest to understand. Arrays are basically numbered lists of related items. They are simple to understand and use, but they are not very efficient when working with large amounts of data. Linked lists are more complex, but they can be very efficient if used properly. They are good choices when you will have to add or remove items in the middle of a large list, or when you need to search for items in a large list.

Q: 2. What are the differences between linked list and arrays?

In arrays, an index is used to access an element. Elements in the array are organized in sequential order, which makes it easy to access and modify elements if an index is used. Array also has a fixed size. Elements are allocated at the time of its creation. In linked list, a pointer is used to access an element. Elements of a linked list are not necessarily stored in sequential order. A linked list has an unknown size because it can contain nodes at the time of its creation. A pointer is used to access an element, so memory allocation is easier.

Q: 3. What is a pointer in C?

A pointer is a data type in C which stores the address of any variable or function. It is generally used as a reference to another memory location. A pointer can hold a memory address of an array, structure, function or any other type. C uses pointers to pass values to and receive values from functions. Pointers are used to dynamically allocate memory space.

DevOps Engineer: Job Description

A DevOps Engineer is an IT professional who works with system operators, software developers, and other team members to handle code releases. They merge the barriers between software development, operations, and testing teams while keeping the current networks in mind for designing, planning, and testing.

A DevOps Engineer must be an expert at IT infrastructure management which is necessary for supporting the software code in multi-tenant, dedicated or hybrid cloud environments. In DevOps, the operations teams and development teams merge to match the software demands of the industry. Therefore, DevOps Engineers have to perform numerous functions during an application lifecycle.

2. Continuous Delivery

In continuous delivery, a software development team produces software in short cycles. This ensures that the software can be released at any time with reliability. Continuous delivery allows development teams to build, test, and release software with much quickness and frequency.

3. Continuous Integration

In continuous integration, you merge the alternations in the code by all the developers into a central repository that runs the automated builds and tests. Usually, developers have to integrate the code into a shared repository several times a day.

4. Microservices Architecture

This design approach focuses on the development of a single application as a part of small services. It arranges an application as a collection of multiple coupled services and is a variant of the service-oriented architecture structural style.
