 So it is not easy to have a list of OpenStack components/services all in one place. They are everywhere on the web and one can easily get lost. and when you do see a list of services, they are not described in a simple way. So here is an easy-to-understand list describing the OpenStack components […]

Looking for Open RAN tutorial ? What is Open RAN/O-RAN and why it matters for mobile operators and vendors? In fact, as wireless networks continue to grow, O-RAN is becoming more relevant for Mobile networks. For one, disaggregation of RAN has remained non-existent. Thanks to a few big vendors’ monopoly. The RAN has been largely […]

OK, you have heard enough of these terms perhaps from RAN vendors? C-RAN vs Cloud RAN vs vRAN vs O-RAN in the context of Radio Access Network ( RAN) However, these terms are not clear to you because everyone out there explains them in a way that is enough to confuse many. The fact is […]

Let’s face it, we all love to have everything cloud native based including cloud Native VNFs. In practice, however, we need to live with the legacy VNFs. The legacy VNFs are monolithic with bulky code and operated in some cases as all in one virtual machine. They can be called virtual, but not cloud-based or […]

For a while I thought to write about an OpenStack cheat sheet showing OpenStack components, so you can refer to it as an easy to use handy reference. If you are using NFV, you are using OpenStack for sure. OpenStack sits at the VIM layer inside NFV MANO and is the most important piece to […]

What is Kubernetes ? and how is kubernetes architecture ? To start with, Kubernetes, also known as “K8s” is an open source container orchestration platform that automates the deployment, management, load balancing, and scaling of container based applications ( also called containerized applications). Secondly, Kubernetes is a leader in container orchestration as this survey shows. In fact, […]

What is Cloud Native ? Answering this question is important as everyone talks about Cloud Native but very few are aware of all the attributes of Cloud Native applications and architecture. For example, many associate cloud native to the use of the containers only. which is not correct. As there are other attributes that also […]

It is not easy to settle the debate for DPDK vs SR-IOV-the technologies used to optimize packet processing in NFV servers. For one, you will find supporters on both sides with their claims and arguments. However although both are used to increase the packet processing performance in servers, the decision on which one is better […]

Having knowledge about NFV without understanding how Network Services/ VNF Forwarding Graphs are created, is like owning a car without knowing how to drive it. “Network Service” (NS) holds importance in NFV as in the majority of cases, VNFs connect with one another to create services instead of working alone. Also, VNFs connect to create […]

Think about NFV! Think about x86 processor ….Both of them are inseparable. Isn’t it? No matter how simple a processor (compute part) sounds, I bet a lot of people don’t know that the compute domain in NFV is not just the compute processor of the node…Actually it is much more. The fact is that the […]
