[...] Broadcom will get blood from the stone, rest assured. They will continue to raise maintenance and licensing fees until they very last customer turns off their last ESXi box. If you think IBM and mainframe is bad, you've never lived with a technology that Broadcom has acquired.
Recently we had a report from a user who had seen a stunning 90% performance regression after upgrading his server to a Linux kernel with KPTI (kernel page-table isolation – a remedy for the Meltdown vulnerability).
他們發現 90% 是因為 VMware 舊版本無法使用 CPU feature 加速，在新版應該可以改善不少。但即使如此，文章內還是在實體機器上看到了 40% 的效能損失：
A big deal of those 90% was caused by running in an old version of VMware which doesn’t pass the PCID and INVPCID capabilities of the CPU to the guest. But I could reproduce a regression around 40% even on bare metal.
This offering is sold, delivered, supported, and billed by VMware. It supports custom-sized VMs, runs any OS that is supported by VMware, and makes use of single-tenant bare-metal AWS infrastructure so that you can bring your Windows Server licenses to the cloud. Each SDDC (Software-Defined Data Center) consists of 4 to 16 instances, each with 36 cores, 512 GB of memory, and 15.2 TB of NVMe storage. Clusters currently run in a single AWS Availability Zone (AZ) with support in the works for clusters that span AZs. You can spin up an entire VMware SDDC in a couple of hours, and scale host capacity up and down in minutes.
網路層也不同，甚至支援 multicase：
The NSX networking platform (powered by the AWS Elastic Networking Adapter running at up to 25 Gbps) supports multicast traffic, separate networks for management and compute, and IPSec VPN tunnels to on-premises firewalls, routers, and so forth.
目前只有在 us-west-2 可以用：
This service is initially available in the US West (Oregon) region through VMware and members of the VMware Partner Network.
Assuming, for illustrative purposes, a valuation for each share of tracking stock of $81.78, the intraday volume-weighted average price for VMware on Wednesday, October 7, 2015, EMC shareholders would receive a total combined consideration of $33.15 per EMC share and the total transaction would be valued at approximately $67 billion.
