API Gateway vs Service Mesh - Which One Do You Need

The increasing complexity of modern software systems with multiple independently deployed services communicating has led to the need for managing communication effectively.
In a service-based architecture, services communicate over the network, making concerns like retries, authentication, rate limiting, and observability more challenging to handle.
To address these challenges, engineering teams often opt for either an API gateway or a service mesh to make service communication more manageable, secure, and observable, although each serves different purposes.
Understanding the key differences and usage goals between API Gateways and Service Mesh can help in making informed decisions on which solution best fits the specific requirements of a system.

Software Development Life Cycle: Systematically building professional applications

The Software Development Life Cycle (SDLC) is a structured roadmap for building scalable and efficient software with clear customer needs and goals.
The SDLC consists of six primary stages: Planning, Design, Development, Testing, Deployment, and Maintenance.
The initial stage involves defining the problem scope, conducting research, and creating a Software Requirement Specification (SRS) document.
Designing Architecture in the SDLC involves structuring components, creating a prototype, and generating a Software Design Document (SDD).
Development phase includes coding based on the SRS and SDD, choosing programming languages, frameworks, and tools cautiously.
Testing phase ensures quality and robustness through unit testing, integration testing, and security testing.
Deployment involves preparing the software for distribution, user guides, terms-conditions, and support forums, along with alpha and beta releases for feedback.
Maintenance phase addresses bugs post-deployment, with support channels providing bug-fixing and updates to enhance the software continually.
Different SDLC models exist based on software type, market factors, and deployment platforms, with the agile Scrum model being popular in industrial applications.
Adhering to proper SDLC principles is crucial for scalability and professionalism in modern technology development, emphasizing workspace discipline and efficiency.
Developers should familiarize themselves with modern SDLC practices to align with the demands of large-scale, data-driven projects.

A Brief History of Fuel Cells

Fuel cells are devices that convert a chemical reaction into electricity, similar to batteries but with key differences.
They consume chemicals and produce electricity as long as there is fuel, while batteries store energy.
Fuel cells have an anode, cathode, and electrolyte, where a catalyst causes fuel to oxidize and generate electric current.
The first fuel cell was made by Sir William Grove in 1838, using dilute acid and copper sulphate.
Different types of fuel cells use varied fuels and produce byproducts like water, carbon dioxide, and electricity.
Common types include alkaline, solid acid, phosphoric acid, molten carbonate, and solid oxide fuel cells.
Fuel cells have been widely used in space missions due to their efficiency and ability to utilize hydrogen and oxygen.
Stationary and mobile fuel cells offer benefits like no moving parts and clean energy production for various applications.
Efforts have been made to introduce fuel cells in vehicles like buses, trains, forklifts, airplanes, and motorcycles.
Although DIY fuel cell projects exist, commercial adoption faces challenges like hydrogen storage and distribution.
