What is Prometheus, Grafana, and How to learn Online?

Prometheus is an open-source system monitoring and alerting toolkit originally built at SoundCloud. Many companies and organizations have adopted Prometheus and have a very active developer and user community in the project. It is now a standalone open-source project and is maintained independently of any company.

Features of Prometheus:

  • A multi-dimensional data model with time series data identified by metric name and key/value pairs.
  • PromQL, a flexible query language to leverage this dimensionality.
  • No reliance on distributed storage; single server nodes are autonomous.
  • Time series collection happens via a pull model over HTTP.

So, it’s always good to find tools that can make work faster and make you more productive. Today we are going to talk on Virtualization tools. In this article I’m going to share a list of top 5 virtualization tool which will definitely help developers to improve their productivity and allow them to build better applications faster.

But, before that let’s have Quick introduction to Virtualization

Virtualization is a process in which, with the help of tools you can create a virtual version of resources like memory, operating system , server or networks instead of deploying the actual resource. In simple words you can understand it like this way: Virtualization let you run or operate a single computer into multiple ones. It let you run a Mac OS on Linux or Windows system in a single computer simultaneously. The Windows, Mac, Linux, or other system running in the virtual machine acts exactly as if it were running on real hardware. The same thing apply with storage, server or networks.

Basically Virtualization tools are used for server consolidation. But they are useful for software developers for writing or testing software.

If we look on to the benefits than these are the major benefits of Virtualization.

  1. Lessen the number of Hardware Resources
  2. 80% server use possible
  3. Cut IT costs
  4. consolidated hardware to achieve higher productivity from fewer servers

Top 4 open source alternatives to Slack for team collaboration and Chat

Off course Slack is market leader in terms team collaboration and Chat but here are the list of 4 open source alternatives to Slack for team collaboration and Chat.
Slack 
Slack offers a lot of IRC-like features: persistent chat rooms (channels) organized by topic, as well as private groups and direct messaging (again, historically based on IRC).[14] All content inside Slack is searchable, including files, conversations, and people. Slack integrates with a large number of third-party services and supports community-built integrations. Major integrations include services such as Google Drive, Trello, Dropbox, Box, Heroku, Crashlytics, GitHub, Runscope and Zendesk. In December 2015, Slack announced their app directory, consisting of over 150 integrations that users can install.[21] Users can add emoji buttons to their messages, which other users can then click on to express their reactions to messages.
More info – https://slack.com/
IRC
Internet Relay Chat, or IRC, is a protocol which dates back to the late 1980s. Since it’s been around so long, there are numerous open source implementations on both the client and the server side.
Coming with its age, however, are numerous drawbacks. It lacks many features one might expect in a modern chat client, from security to identity management to even just being able to easily transmit non-text components, like images, files, or emoticons (the latter might be seen as a plus to some, however). Some features have been implemented after-the-fact through bot services, including nickname management, logging, and other features, but these vary from server to server.
IRC does still have some things going for it, though. It’s nearly universal, and clients are available for basically every platform out there. Though the command-driven interface isn’t necessarily intuitive for beginners, many clients re-implement commands through a GUI. And if you’re doing upstream open source development, there’s a good chance you’re already hanging out in IRC anyway, so adding a team server might be a path of least resistance.
Let’s Chat
Let’s Chat is a persistent messaging application that runs on Node.js and MongoDB. It’s designed to be easily deployable and fits well with small, intimate teams.
It’s free (MIT licensed) and ships with killer features such as LDAP/Kerberos authentication, a REST-like API and XMPP support.
Let’s Chat is a side-project of the development team at Security Compass. (A real life 10% time project!)
More –
Mattermost
As an alternative to proprietary SaaS messaging, Mattermost brings all your team communication into one place, making it searchable and accessible anywhere. It’s written in Golang and React and runs as a production-ready Linux binary under an MIT license with either MySQL or Postgres.
Rocket.chat
Rocket.Chat is an incredible product because we have an incredible developer community.
Over 200 contributors have made our platform a dynamic and innovative toolkit, from group messages and video calls to helpdesk killer features.
Our contributors are the reason we’re the best cross-platform open source chat solution available today.
