This topic is very hot recently, especially the major outage just happened from the Famous Public Cloud provider : Amazon recently, had created major alert for those users who are currently subscribe or planning to move on to public cloud.

Virtualization had become matured and well adopted by most environment today. The next wave no longer focusing IaaS, but the focus will be more on User Experience such as VDI, Application virtualization, SaaS, PaaS and etc. Matured users will start to look into applications & data availability.Virtual Machine HA fail over are not good enough to provide higher availability.

Virtual Machine could be fail over during hardware failure, how about services failure or the application client server dependency issues? Example : There may be the application or middle ware machine require manual restart during a HA kick in scenario.

Arista Network for Virtualization vEOS vs Cisco Nexus 1000V

Posted on April 19th, 2011 in Announcement, Data Center, Industry News, Virtualization | 2 Comments »

Arista could be fairly new in this region, but they had been proven to be 1 of the reliable and high performing low latency switches in the market today. The main market for them are mainly focus on trading, FSI and high performance environment. Lately, I had noticed Arista start to move into cloud & virtualization market aggressively. While Arista is very aggressive on this, there are some changes or option been brought into the market by them.

10Gbps Ethernet no longer as a dream to most enterprise environment. It had become affordable, and realistic to be adopted while users decided to build the virtualization or private enterprise cloud. I had always highlighted that network had become major component of the success for cloud or virtualization, therefore the manageability on the virtual switch had become equally important as well. Previously, Cisco Nexus 1000V is the only choice to perform virtual switch layer management. If you do not want to go for it, you have another choice here. Arista had a similar offer which is vEOS, that allow virtual traffic direct integrate and visible over to the Arista Physical Network switches.
