Spanning Tree Protocol (STP) is dead, or at least it should be. It’s too slow to converge when there’s a change, and it causes issues with performance because there is only one forwarding path. It was developed in 1985 by Radia Perlman at Digital Equipment Corporation to allow for redundant paths within a Layer 2 topology, which was great in 1985. In fact, it was huge! So much so, that it was later standardized by the IEEE as 802.1D, and we’ve been living with it ever since.
Examine the evolution from physical servers to VMs to containers and the driving factors behind this change. Also review the available container management solutions on AWS, Google Cloud Platform and Microsoft Azure.

This is another topic of heated debate, and it changes from network to network, but I found a simple approach that works in most cases. Since I have four queues and four classes of traffic, I need to categorize my important traffic into four classes. Strictly for explanation purposes I took some liberty in defining four categories of traffic that are very effective in both large and small networks. These classes are: Real Time Protocol (RTP), Network Management (NetMgt), Business Critical, and the Default.
It’s common knowledge that earning an AWS certification is a great way to qualify your experience in the eyes of your peers and employer and to increase your organization’s proficiency with AWS-based applications. However, there is another benefit that has not be quantified until now. Results from the 2015 IT Skills and Salary Survey conducted by Global Knowledge and Windows IT Pro revealed that the average pay of four AWS certifications exceeded $100,000.
