The DevOps market is projected to grow by about 21% between 2018 and 2028, and DevOps engineers remain one of the most in-demand types of engineers. Once you follow these principles, you will be able to work on improving the code quality, delivering the services in-time, and achieving future goals in terms of delivering services and products. Over 3,000 companies and 40% of developers worldwide use HackerRank to hire tech talent and sharpen their skills.

At the same time, developers may need support from DevOps engineers when working to improve the process of building and deploying application code. Infrastructure provisioning and system administration include deploying and maintaining the servers, storage, and networking resources required to host applications. For organizations with on-premise resources this might include managing physical servers, storage devices, switches, and virtualization software in a data center. For a hybrid or entirely cloud-based organization this will usually include provisioning and managing virtual instances of the same components. One of the key roles for implementing a DevOps restructuring is a DevOps engineer. This person must possess a wide ranging skill set that spans both development and operations, but also the interpersonal skills to bridge divides between siloed teams.

DevSecOps, shifting security left

Microservices are built around business capabilities; each service is scoped to a single purpose. You can use different frameworks or programming languages to write microservices and deploy them independently, as a single service, or as a group of services. Organizations might also use a microservices architecture to make their applications more flexible and enable quicker innovation. The microservices architecture decouples large, complex systems into simple, independent projects. Applications are broken into many individual components (services) with each service scoped to a single purpose or function and operated independently of its peer services and the application as a whole.
