In the previous article i created a GNS3 VM on OCI. Further i would like to connect to this VM and use it in order to visualize a network appliance. In order to connect to the VM, I need the GNS3 software installed locally on the laptop. The software is free, however, I need to create an account. I am using a Windows 10 laptop and what i will capture further is on this OS. Download GNS3 from: https://www.gns3.com/software/download After the installation, configure the client...

The following article is intended for network enthusiasts that want to use OCI to create a network lab. The setup that I will demonstrate has no value in production environments.This article is part of a series of 3 blogs on GNS3. I will start from importing thre GNS3 software to OCI, connect to it from a laptop, upload a network appliance firmware an connect it to the internet. I remember my early networking days when I was studying for CCNP and I had no access to a full lab...

/**/ Introduction: In this blog I give an overview for the configuration of load balancers and I will do a practical demonstration that will use the definitions that are presented. Definitions: Load balancers are distributing the requests from the clients to the pool of servers based on an algorithm (policy). There are multiple Load balancer "Shapes" (S - 100Mbps, M - 400Mbps, L - 8000Mbps). The Shape is the total throughtput that can be handled by the load balancer. The...

.cb11w1 ul li, .cb11w1 ol li { line-height: 1.4em; color: #404040 } GlusterFS is a well known, scalable, high performance shared filesystem. It is easy to install either on premises or in the cloud. Guides for this can be found in many places, including here and here. However, after you built your second or third Gluster environment, you start thinking of automation, especially when you are in the cloud. Automation not only provides a quick way of creating a new environment...

I decided to write this blog post because I received multiple customer requests asking for differences between NSGs and SLs, where and when to use one or another or both and the best practices. NSGs stands for Network Security Groups, a security mechanism that we have added to OCI few time back. NSGs can be more granular in terms of security and can be used with or without Security Lists, You can follow the link from OCI public documentation to find more about NSGs vs...

Introduction There are some cases when our customers are reporting that the TCP connections from On-premise to OCI just hangs apparently without any good reason. In the next discussion we will introduce an important detail that usually is not taken into consideration when the connection hanging troubleshooting is made. The case discussed is when the TCP three way handshake completes successfully but when starting sending the data the connection is hanging. Why? In modern TCP...
