Cloud Load Balancing



Server Load Balancing used to be the very center piece of a business network. A few years ago, typical enterprise would host hundreds of specialized ERP, CRM, and Databases servers on the local network. Server Load Balancer would distribute the resources across the servers. Recent years, with the increasing popularity of Cloud Computing, enterprise is moving to the cloud platforms such as Salesforce CRM, Google App Engine, Amazon EC2, Microsoft Azure, or IBM CloudBrust. Cloud allows enterprise to scale their computing resource at a click of a button. All thousands of server can be consider as one single unit. This trend has transformed the way business networks are being built. And with flexibility like this, is server load balancing still necessary?

Server Load Balancing will become Cloud Balancing
We believe Server Load Balancing will stay, but it will evolve in a form of Cloud Load Balancing. The reason is that even with Amazon or Google experience and expertise on the cloud computing, downtime occurred. Enterprise has to build their own private cloud as backup. A new cloud load balancing technology will blend the backup into the existing cloud deployment. New cloud load balancing technology will soon appear on the market.

Cloud Balancing SaaS
This Cloud Balancer, will no longer be a hardware, but as a SaaS that exist among multiple cloud services for redundancy. It will be as simple as a web application that let you key in the essential information such as domain, ports, clouds, and numbers for user sessions. Bingo, a new cloud balancer is now ready to redirect user request, to your own mix of public and private clouds.

This will happen so fast that I predict some form of this launch in the year of 2010, and become popular in year 2012. In fact, the F5 guy is also talking about this.

Simpler Network in Business Sites
Server and SLB will be taken away from office and placed in the cloud. Internet, will therefore, plays an increasingly important role in business networking. This also means for the office, you will now need even more reliable Internet access. With the servers, server load balancer, and the firewall taken away from the picture, the future of business network is as simple as a Router and Switches. A dual-wan or multi-wan router, will soon become the industry standard. This is why we are so enthusiastic about multi wan router.
