The following popular protocols are supported, VNC, RDP, SSH, Telnet. Architecture Guacamole consists of the following components:
In this post, I am gong to present a way to set up Guacamole server in Azure free tier cloud VM. I am using docker technology with the help from Docker Web UI Portainer, to deploy a Guacamole docker into a Linux virtual machine.
In this post, I am put all of following topics together
Benchmark Free Services for AWS, Azure, GCP All of AWS, Azure and Google Cloud are providing some kind of free tier to the users. I am always wondering how those free tier VPS performance looks like. I did some bench work to test them out. Here is the method and result. I am going to use some bench scripts found from github and running them through the same size VM created on AWS, Azure and GCP. It will benchmark their CPU, Disk IO, network throughput
DevStack is an opinionated script to quickly create an OpenStack development environment. It can also be used to demonstrate starting/running OpenStack services and provide examples of using them from a command line. This post is going to present the steps how to install DevStack into a VMware workstation Ubuntu VM.

Gartner's Magic Quadrant for Public Cloud Infrastructure Managed Services Providers (2018, 2017)7/14/2018 What are Public Cloud Infrastructure Managed Service Providers?Public cloud infrastructure as a service (IaaS) delivers compute, storage and network resources in a self-service, highly automated fashion. The leading public cloud IaaS providers also offer platform as a service (PaaS) capabilities and other cloud software infrastructure services as part of an integrated IaaS+PaaS offeringThis Gartner magic quadrant report analyzed vendors in the market and states that “a public cloud infrastructure managed service provider (MSP), in the context of this Magic Quadrant, is an MSP that offers managed services and professional services related to infrastructure and platform operations for one or more hyperscale integrated infrastructure-as-a-service (IaaS)+platform-as-a-service (PaaS) providers.”

I have selected Ubuntu as OS platform to install my php, wordpress and mysql. It gave me lots of learning experience on Linux. Here is many steps I recorded during working on my 51sec.org blog site.

I was looking for some online tools to create impressive AWS diagram for my learning process. Most of online diagram websites provide certain free usages. In my My Top Internet / Network Tools post, I mentioned following online diagram drawing websites which I used before:
Here are some good AWS diagram websites I found useful to me. 1. AWS 3D Diagram from Cloudcraft.coIt is quite impressive when I started to make my first diagram. Limit grid size is a big pain when you try to draw a detail diagram for your AWS VPC, but it is good enough to draw a three tier application deployment. Cloudcraft allows registered user to create AWS diagrams for free using all available components with some feature limited. Upgrade to Cloudcraft Pro for import of live AWS data and unlimited size diagrams. It can automatically calculate the cost for your design, and also provides live connection to your AWS account. The smart components feature makes it much easier to connect other components you lay on the grid than any other websites I tried. Love it. So far, I think it is best site for me . Monthly $49 can get your subscription to pro level to unlock those restrictions. 3. Building a scalable AWS architecture (ELB, ASG, RDS)
