An integrated development environment (IDE) is one of the essential components of a software project. It facilitates the development process. IDEs improve developer productivity by reducing the time it takes to set up, speeding up development work, keeping developers up to date on the latest risks and best practices, as well as standardizing the development workflow so that anyone can take part. IDEs also help to streamline development. They allow programmers to think of their work as a whole software development lifecycle (SDLC) instead of a series of isolated steps.   The 8 Best Java IDEs:   1. Eclipse Eclipse is an open-source Java development environment for developers. Most of its code is written in Java. With Eclipse, we can create cross-platform applications for mobile devices, web browsers, desktop computers, and enterprise applications. We can easily add multilingual support and other functionality to any of our built-in packages, and we are rewarded with virtually li...

In the past, data was stored on a hard drive on a computer. Today, cloud computing services have replaced hard drive technology. A cloud computing service is nothing but the provision of services such as Storage, Database, Servers, Networking, and Software over the Internet. Few Companies provide these computing services, therefore they are referred to as Cloud Computing Providers / Companies. They charge their users for using these services. The charges are based on the usage of services. With the help of cloud technology, we can create and develop new applications, save and store data, and even host the website. Here is a list of the top Cloud Services implementations. 1.  Amazon Web Services It’s the most popular because it was the first of its kind in the cloud computing world. Whether you’re looking for compute power, database management, content distribution or other features, AWS has the tools to help you build advanced applications with increased flexibility, scalab...

NoSQL , which stands for “ not only SQL ,” is an approach to database design that can accommodate a wide variety of data models, including key-value, document, columnar, and graph formats. NoSQL  is an alternative to traditional relational databases in which data is placed in tables and data schema is meticulously designed before the database is built.  NoSQL  databases are especially utilizable for working with large sets of distributed data.  NoSQL Features & Capabilities  Performance  Availability  Multi-Model  Concurrency  Security  Scalability  Data Model Flexibility  Deployment Model Flexibility  Today, we will see a  list of top NoSQL databases. MongoDB MongoDB is a cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas. Documents consist of key-value pairs which are the basic unit of data in MongoDB. Collections cont...

Two-factor (2FA) or multi-factor authentication (MFA) is a supplemental security layer for our business – availing to address the vulnerabilities of a standard username-password-only approach. In today’s digital environment, the rudimentary “username and password” approach to security is facile prey for hackers. Many log-ins can be compromised in minutes, and private data is under incrementing threat. Multi-factor Authentication, additionally kenned as MFA or multi-step verification, integrates another layer of security, supplementing the username and password model with a code that only a concrete utilizer has access to (typically sent to something they have immediately to hand).  Why is it required?  • Legacy Authentication & Authorization alone are not enough   • No way to verify the end-user utilizer is our authentic subscriber  • No way to verify the end-user utilizer is bound to his/her account services Implementation - High-level Overview How does two...

PlantUML is an open-source implement and syntax for engendering diagrams from plain-text definitions. We utilize simple text syntax to describe a type of diagram, as well as the elements which make up the diagram, and our away. Utilizing this plain text syntax and a rendering server/plugin to convert our text into diagrams, we can draw near on any architectural diagram that we require when designing a system. Here are just a few of the types of diagrams we can engender: Sequence diagram Usecase diagram Class diagram Object diagram Activity diagram  Component diagram Deployment diagram State diagram Timing diagram Steps to create sequence diagrams    Step 1:  Download and Install Visual Studio Code : https://code.visualstudio.com/download Step 2: Add PlantUML extension for Visual Studio Code  Install the extension Step 3: Create a text file with PlantUML commands, like this example called sequenceDiagram.txt: @startuml skinparam SequenceMessageAlignment ce...

Cloud monitoring is the process of evaluating, monitoring, and managing cloud-predicated services, applications, and infrastructure. It’s generally implemented through automated monitoring software that gives central access and control over the cloud infrastructure. This perpetual evaluation of resource levels, server replication times, and speed predicts possible susceptibility to future issues afore they arise. Types of cloud monitoring are   Database monitoring  Website monitoring  Virtual network monitoring  Cloud storage monitoring  Virtual machine monitoring In this article, we list down the top cloud monitoring tools, 1. CloudWatch Amazon CloudWatch is a monitoring and observability service. CloudWatch provides us with data and actionable insights to monitor our applications, respond to system-wide performance changes, optimize resource utilization, and get a coalesced view of operational health.  CloudWatch amasses monitoring and operational data in...
