Cloud Networking – Once More Into The Breach
Anyone who has been in networking for several years has seen an exorbitant amount of change. Initially, businesses had physical (racks and chassis) network and switching equipment that resided on their physical premises. This was their corporate network consisting of routers, switches, servers, etc. The simple network concept expanded to include wide area networking, international and distributed offices, and then extensive security measures including IPS, IDS, DLP, WAF, etc.
The concept took a quantum leap as we went through a “virtualization” mania a few years ago. Everything needed to be moved to virtualized servers located in the virtual data center. Now we are on the precipice of another quantum leap, the use of cloud networking, where a significant majority of capabilities are being moved to either public or private cloud networks.
Whether you are a proponent of this move to the cloud or not, there are some things to consider if, and when, you decide to take the plunge. While there has been a lot of hype around the benefits of cloud computing, very little is being said about the inherent drawbacks.
