What is High Performance Computing (HPC)?
High Performance Computing (HPC) refers to the use of supercomputers and parallel processing techniques to solve complex computational problems that are beyond the capabilities of a single computer. HPC systems use clusters of computers, connected by high-speed networks, to work together in parallel to perform very large computations. Applications of HPC include weather forecasting, molecular…

What is containerization?
Containerization is a technology in the field of Information Technology (IT) that allows you to package and isolate applications and their dependencies into lightweight, portable containers. This makes it possible to run multiple containers on the same host, each with its own isolated environment and resources, without affecting each other. Containers offer several advantages over…

What is hardware virtualization?
Hardware virtualization is a technology that enables multiple virtual machines (VMs) to run on a single physical server. Each virtual machine is isolated from the others and operates as if it were running on its own dedicated hardware, even though the underlying physical resources are shared among multiple VMs. This allows organizations to achieve better…

How to build resilient IT infrastructure?
Resilient IT infrastructure refers to the ability of an organisation’s information technology (IT) systems and infrastructure to withstand and recover from disruptive events, such as natural disasters, power outages, cyber-attacks, and other emergencies. A resilient IT infrastructure is designed to provide continuous availability and accessibility of critical data and services, even in the face of…

What is big data?
Big data is a term used to describe extremely large datasets that are too large to be processed and analyzed using traditional software and hardware. Big data is characterized by its volume, velocity, and variety. The volume of big data is the sheer size of the data, which can range from terabytes to petabytes. The…

What is Apache Hadoop?
The core components of Hadoop are HDFS (Hadoop Distributed File System), MapReduce, YARN (Yet Another Resource Negotiator), and Hadoop Common. HDFS is the distributed file system that stores data across multiple nodes in a cluster. MapReduce is a programming model for processing large data sets in a distributed manner. YARN is the resource management layer…

What is a data mesh?
Organizations should consider using a data mesh if they need to manage a large volume of data and need greater control over data security and privacy. A data mesh is an architecture for managing data that is based on mesh-like networks of data services. Data mesh architectures are decentralized and focused on autonomy and resilience,…

How to build a data pipeline?
A data pipeline is a set of data processing elements connected in series, where the output of one element is the input of the next one. Data pipelines automate the flow of data from one system to another and enable the transformation, validation, and analysis of data. They are used to move data between different…

What is event-driven architecture?
Event-driven architecture (EDA) is an architectural style that allows applications to communicate with each other through event-based interactions. It is an architecture pattern that enables communication between components of an application or system by exchanging events. Events are sent by a producer, consumed by a consumer and are routed to the next consumer by an…

What are microservices?
Microservices are a software architecture pattern where an application is built as a suite of services, each of which runs in its own process and communicates with lightweight mechanisms, often an HTTP resource API. These services are independently deployable and scalable and are organized around business capabilities. The microservice architecture enables the continuous delivery/deployment of…
