Introduction to Azure Active Directory

Introduction:

In organizations, employees often need access to various Azure services to perform their tasks. They can use services like SQL database or Azure container services when the system administrator assigns them a user id and password for each service. However, managing multiple user logins for each service can be a hassle for administrators, especially in organizations with over 1000 employees. Azure Active Directory (AD) helps solve this issue by enabling administrators to manage multiple user logins in a centralized manner.

Self-Hosted GitLab Migration – Part 1

In the IT industry, the need for migration can raise several questions in your mind. Like what will be migrated and what measures should be taken to perform the particular migration. And the major concern is whether there are any chances of losing data. Losing even a tiny fraction of the data in transition can impact the performance of the application. So, in that scenario there are several measures that need to be kept in our mind while performing any sort of migration is taking a backup of the data, software configuration, and if any plugin is required for the software so that should also be checked. Apart from that migration should always take place when the least traffic comes on the application.

So, recently we got a requirement where we had to upgrade a self-managed Gitlab Community Edition(CE) from 11.11 to the latest version i.e., 15.4.

While upgrading Gitlab to any other version you might face many problems related to incompatible versions. So, for a successful upgrade, we’ll discuss the GitLab requirements for the upgradation and will also share the analyses that we found while following through this blog post.

How to Setup Consul through the OSM Ansible Role

Are you searching for service discovery or a service mesh tool for a distributed environment?

Did you find any with easy installation? Not yet!! Think fast….It’s just a piece of cake.YES! NO! Calm down because I got it !!!!

A few days back we got a requirement where we had to setup multiple services on multiple servers and in a cluster mode….So now the question arises how will the services be auto discovered? how will we get to know the health check of the service? and above all how to restrict users on different services. After a lot of research, I came across a tool named as consul. But now another stumbling block arises HOW TO SETUP IT?

Your answer might be just go ahead and download the binary on every server, if that’s what you’re thinking…then STOP! Because doing it manually on plenty of servers is time-consuming and also not an efficient way. So, I thought of using a configuration management tool that is none other than ansible. Then there were roles that were already present in the market but some have the hard coded encryption key, some were not generating the bootstrap token and also they were not easy to understand. None of the roles fulfilled the requirement.

So, I thought of creating an ansible role with features like, enabling ACL and generating a bootstrap token, and an encryption key with easy-to-understand language.

In this blog, I have explained the OT-OSM consul ansible role.

Without any delay let’s get started!!!

Now you might be thinking what is consul?

How to fix the dpkg lock file error in Packer?

Today everyone is switching to cloud platforms. To this, we need to install basic software or modify certain Configurations in each server and to all this, we call prerequisites. So we have a concept of creating a BASE IMAGE and GOLDEN IMAGE. We were creating Golden Server Image for one of our clients using Packer to fulfill the prerequisites, and it is when I faced this issue.

‘E: Could not get lock /var/lib/dpkg/lock’

Firstly, we will talk about Packer.

Introduction to Siege

Several factors play an important role in order to make a business succeed. One of them is its online presence in today’s world. In simple words, online presence means an informative and attractive web page. Web page/server are the mirror reflection of how successful a business is. It is crucial to have a stable web server as the performance of an application or a web server will define the user experience which will have a direct impact on business as well.

Now you must be thinking if a web page is so important, so it should be able to function efficiently when in use. The stability of a website is a matter of concern in case of an extreme situation which highlights the importance of testing the web server. By testing, we mean load testing and performance testing which will give stress to the website and tells its performance under stress.

Now you must be thinking testing will require a huge cost and effort for servers which sometimes makes us skip the testing phase. Let me help you in solving this doubt by introducing you to “Siege” which will make testing a simple and achievable task.
