Reading Time: 4 minutes Introduction One of the biggest challenges associated with big data is, analyzing the data. But before we get to that part, the data has to be first collected, and also for a system to process impeccably it should be able to grasp and make the data available to users. This is where Apache Kafka comes in handy. Let’s briefly understand how Kafka came into existence? Continue Reading
Reading Time: 3 minutes Rust has been the most loved programming language for the last five years in a row. It is a low-level statically-typed multi-paradigm programming language that’s focused on safety and performance. Rust has facilities for message passing through an mpsc channel which allows various threads to communicate. Rust solves problems that C/C++ has been struggling with for a long time, such as memory errors and building concurrent programs. Due to the borrow checker, Rust can prevent data races at compile-time. Data races Continue Reading
Reading Time: 3 minutes The Design Patterns are programming language independent strategies for solving a common problem. By using design patterns, you can make your code more flexible, reusable, and maintainable. These solutions were obtained by trial and error by numerous software developers. Types of Design Patterns There are following types of design Patterns in Rust for solving our problems : Behavioural Creational Behavioural Patterns Behavioural design pattern are design patterns that Continue Reading

It has a large, quickly developing ecosystem. Kubernetes services, maintenance tools are widely available. Why you require Kubernetes and whatever it can take In addition, Containers are good method to bundle and run your applications. In a production background, you need to maintain Continue Reading
Reading Time: 3 minutes Firstly, Ansible is simple open-source IT engine that automates application deployment, infra service orchestration, cloud provisioning and many other IT devices. Secondly, Ansible uses playbook to define automation jobs, and playbook use very simple language i.e. Hence the profit is that even the IT infrastructure maintenance people can know and understand the playbook and debug if needed (YAML – It is in human-readable form). In conclusion, After Continue Reading
Reading Time: 3 minutes Firstly, Chef is open-source technology Adam Jacob, co-founder of Opscode recognised as the originator of Chef. This technology uses Ruby encoding to develop basic construction blocks like recipes and cookbooks. Chef is use for infrastructure automation and helps minimising manual and repeated tasks for infrastructure management. Chef got its own law for different building blocks, which required to manage and automate infrastructure. Why Chef? In Continue Reading
Reading Time: 4 minutes Prometheus is an open-source monitoring system for processing time series metric data. It collects, organizes, and stores metrics using unique identifiers and timestamps. DevOps teams and developers query that data using PromQL and then visualize it in a UI such as Grafana. Basic Terminologies of Prometheus Monitoring : Monitoring is a systematic process of collecting and recording the activities taking place in a target project, Continue Reading
