Ansible is an open source software product that automates configuration management, application deployment, and software provisioning. It connects through SSH, remote APIs and through remote PowerShell. It is one of the best IT automation engines that have the ability to remove drudgery from the work life of the users. It also helps in dramatically improving the consistency, reliability, and scalability of an IT environment. Different varieties of automatic repetitive system administration activities can easily be performed by the use of Ansible.
How to Use Ansible?
There are three varieties of tasks that can be automated with the use of Ansible and they are as follows:
- Configuration Management- Ansible can effectively be used for changing the configuration of different applications and operating systems and even devices. It can also be used for starting and stopping services; installing and updating applications; implementing security policies and for performing a wide assortment of other configuration procedures.
- Provisioning- Ansible is best for setting up different servers required in an infrastructure.
- Application Deployment- Ansible can automate the deployment of applications that are internally developed for different production mechanisms.
Apart from the above-mentioned automation tasks, Ansible has the capacity of automating IT environments irrespective of the fact that whether they are hosted in the cloud, on virtualization platforms or on the conventional metal servers. Ansible also has the potential of automating the configuration of different devices and systems like storage, networks, databases, and firewalls. The best thing about using this open source software product is that you do not need to know any of the commands that are used for achieving a certain task.
OpenShift is basically a software product that comes from Red Hat. It can be used for container-based management and deployment. It is a specifically designed software product meant to provide complete ease of use to developers. The main mission served by OpenShift in Red Hat is making your job easier by taking good care of all the confusing and chaotic aspects of application development in the field of information technology. It allows the developer to have their focus on coding their application and satisfying the requirements of their clients.
Red Hat OpenShift comes powered by fully proven open source technologies which include OCI-standard containers, Red Hat Enterprise Linux and Kubernetes for management and orchestration. OpenShift is Red Hat is also called Red Hat OpenShift Online, OpenShift Origin, OpenShift Container Platform, OpenShift.io. and OpenShift Dedicated. It is also worth noting that the product offers a completely-incorporated container stack and without the complexity of locking the users into proprietary solutions or defaults. Users get the flexibility of choosing their very own networking, registry, CI/CD solutions, and storage. They can get immediately started with the use of default OpenShift alternatives.
In-Built Automation and Extensible
OpenShift perfectly automates application and container builds, scaling, deployments, source code management, and health management. It also extends for giving users their individual choice of databases, runtimes, and frameworks. OpenShift is Red Hat also offers self-service to the users in regards to public cloud services by way of its Service Catalog. It comes with professional support available from Red Hat- a well-known open source software leader in the world.
Cucumber can be defined in the form of a software device that is primarily used by developers and computer programmers. This software tool is used for testing different software products. Cucumber basically carries out automated acceptance analyses noted in BDD or behavior-driven development style. The main feature of the Cucumber BDD approach is its simpler language parser that is known as Gherkin. Gherkin allows software behaviors expected to be specified in logical language for the ease of understanding of the customers. Therefore, Cucumber makes way for the execution of characteristic feature documentation in the form of business-facing model. Therefore, it would not be incorrect to say that Cucumber is a tool that supports BDD and offers users to write tests that can be understood by anybody regardless of whether they have a technical understanding or not.
What are the Advantages of Using Cucumber?
In Behavior Driven Development, the users are generally product owners and business analysts. They write acceptance tests or scenarios at the first place for describing the system behavior as per the perspective of the customers. These acceptance tests are written for the purpose of review and further sign-off by the owners of the product before the developers write their codes. Cucumber has its focus on the experience of the end-user. It is one of the most efficient testing tools that can easily and quickly be set up and executed. It is one of the most helpful tools for involving business stakeholders who do not have the knowledge or the understanding required for reading codes.
