How does blockchain work? It works with Blocks, where a spreadsheet works with “rows” and “columns.” A block in a blockchain is a collection of data. Blockchain is a distributed ledger, which means that a ledger is spread across the network among all peers in the network, and each peer holds a copy of the complete ledger.
How does public-key cryptography work? What is a private key and a public key? Why is asymmetric encryption different from symmetric encryption? Asymmetric encryption, also known as public-key cryptography, is a cryptographic system that uses a pair of related keys: public and private. The public key can encrypt data, but […]
Docker is an open source platform that’s used to build, ship and run distributed services. Kubernetes is an open source orchestration platform for automating deployment, scaling and the operations of application containers across clusters of hosts. Microservices structure an application into several modular services Learn the basics of Microservices, Docker, and Kubernetes. Code demo starts […]
This tutorial shows how to use OpenSSL in Linux systems (Kali in the video) for symmetric and asymmetric encryption and decryption. OpenSSL is a free and open-source toolkit that provides a robust, commercial-grade, full-featured toolkit for general-purpose cryptography and secure communication. Internet servers, including most HTTPS websites, widely use it. […]

REST API has no official standard because it is an architectural style. SOAP API, on the other hand, has an official standard because it is a protocol. REST APIs use multiple standards like HTTP, JSON, URL, and XML, while SOAP APIs are primarily based on HTTP and XML. REST allows more data formats, whereas SOAP only allows XML. Coupled with […]
What is Web service? What is API? What is REST API? How REST works Implementation of REST API A web service is a software system that supports interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL). Other systems interact with the web […]
All is not entirely rosy in microservice-land. It’s often a sign of an architectural approach’s maturity that anti-patterns begin to be identified and classified alongside well-established principles and practices. Daniel Bryant introduces seven deadly sins from real projects, which, left unchecked, could easily ruin your following microservices project. Daniel offers […]
