Rancher is one platform for everyone who uses Kubernetes and it is an open source software platform that enables organizations to run containers in production. Rancher supports flexible user authentication plugins and comes with prebuild user authentication integration with Active Directory, Lightweight Directory Access Protocol (LDAP) and GitHub. Rancher supplies the entire software stack needed to manage the containers in production.

Here are a few key points which answer, why one to prefer rancher platform:

1. Container Orchestration:

Container orchestration is all about managing the life cycles of containers, especially in large, dynamic environments. The beauty of container orchestration tools…

You can perform a sanity check at this point using the command of rail routes to verify that everything is working properly. Output will contain something similar to the following: Routes

Lets add some seed data to db / seeds.rb before running our server:

# This file will contain all the record creation required to seed the default values for the database.

# The data can then be loaded with the Rails command db: seed (or…


What if a new framework could be deployed with Heroku-like ease without giving up the versatility and cost-savings you get from a more general-purpose platform such as AWS? Using Elastic Beanstalk — an AWS operation, is possible.

In this article, I’m going to walk you through setting up a rails application and running it on AWS using Elastic beanstalk as the compute base and RDS (Relational Database Service)-the Postgres service in particular-as the data storage.

Set up an app with a few routes for Rails 6, and run it locally.

· Creating an account at AWS.

· Using the free-tier…


The web has evolved and so did Ruby on Rails. The framework now provides improved JavaScript tooling, including integrations for both yarn package manager and webpack module bundler — de facto choice in the JavaScript community. Out of the box support for these tools facilitates creation of rich client applications. We can now easier than ever build Rails-backed applications with modern tools like Vue, React and Angular.

However, as we develop our applications with modern JavaScript libraries, a new concern emerges. Feature specs that once brought confidence are now becoming increasingly brittle. Specs that once steadily navigated through almost static…


What Is DocumentDB?

Launched in January 2019, Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, and highly available implementation of the MongoDB 3.6 API. It’s a fully managed document database that supports MongoDB workloads.

Essentially, DocumentDB is a clone of version 3.6, reimplemented for scale. It does not share or use any of the MongoDB source code, meaning it’s a unique implementation, proprietary to Amazon.

The code is closed-source. Amazon felt they needed to create their implementation to improve performance on large data sets, with high throughput for mission-critical workloads. …


SQL statements are the primary means through which businesses and organizations retrieve information from the database. However, these statements aren’t always as efficiently composed as they could be, which can lead to slowdowns from the server. That’s why you hear so much about SQL query optimization — it’s a necessary process if you hope to ensure high levels of server performance.

Part of the process of SQL optimization and tuning involves regular calibrations of SQL queries. Different SQL queries can be used to retrieve the same information, but not all queries are efficient — so it’s important to ensure you’re…


There has been a conversation about Ruby on Rails and the gradual decline in its popularity. We set out to find out whether there was any truth to this conversation. Learn how Ruby on Rails has matured over the years.

There has been a lot of discussion about Ruby on Rails and its future. Some question whether it will survive in the next few years while others rave about its longevity. We looked into the framework’s features and benefits to determine its popularity and relevance in the current market and see if it’s still worth.


SQL is a programming language developed for extracting information from and updating a database. Moreover, SQL also performs various operations like managing data in a relational database management system (RDBMS).

The major difference between INSERT and UPDATE within SQL is that Insert is useful for adding new records within the table whereas Update is useful for changing the existing records in the table. Sql server dba training helps you to learn more effectively.

The INSERT and UPDATE are the DML (Data Manipulation Language) commands in SQL that help to modify data in the table. …


The following article describes how to import the data from an MS Excel sheet to a SQL Server table in Microsoft SQL Server Ver. 2016. This method of importing data from source to target looks very simple for experienced developers. But this is much helpful and useful for beginners who have just started their career in SQL Server.

There are many frameworks where anyone will get the master data from a client in an Excel sheet format. The same we need to load into the server. Now, the user might be thinking about how we could import data into an…


MicroServices:

Essentially, a microservice is a computer program that runs on a server or a virtual computing instance and responds to network requests. Microservice is breaking up an application into smaller parts each of which communicates across interfaces such as API, HTTP.

The benefits of Microservices are:

  • Easier automation testing
  • Rapid and flexible deployment models
  • Higher resiliency

Another success of adopting microservices is the capacity to pick the best tool for the job. …
