I was reading Richard Garsthagen’s article about anti-virus solutions yesterday and decided that this deserved a little bit of extra attention as it is an often overlooked area when it comes to architecture and impact. As Richard points out the difference in terms of load that it generates and overhead is enormous. All of these combined will most definitely result in an increase of consolidation ratio. Not only that but is will also seriously lower the risk during for instance a VDI boot storm but also think about the impact of HA initiated restarts. This could cause an enormous amount of IOps and CPU/Memory overhead which in its turn could impact the other virtual machines.
I guess there is no point in rehashing what is written in the whitepaper of what Richard wrote, I just want to point out the whitepaper as I believe it is a good read. As always results may vary but it is pretty obvious that from an architectural and operational perspective End Point Security is most definitely worth looking into and I cannot wait for more vendors to jump on the bandwagon.
