In addition to Per Core licensing, replacing Per Processor licensing, SQL Server 2012 also introduced new virtualization rights. For SQL Server Standard Edition, the only method of licensing virtual machines is by licensing each individual virtual core (up to the 64-core technical maximum). For the new SQL Server Enterprise Edition – Microsoft’s top-of-the-line database software (replacing Datacenter Edition) – allows for the number of virtual instances equal to number of licensed cores. Thus, a dual-CPU, quad-core server – that is, […]

Microsoft Windows Server Virtualization
Infrastructure grows and its mission evolves. To accommodate increasing workloads, faster, denser (i.e., more cores) processors are deployed, translating into additional investment in software. When Windows Server 2008R2 was released, Microsoft introduced new virtualization rights: – For Standard Edition, one (1) physical operating system environment (“OSE”) and one (1) virtual OSE. This is known as the “1+1” rule. – For Enterprise Edition, one (1) physical OSE and up to four (4) virtual OSEs. This is known as the “1+4” rule. […]
Desktop virtualization and licensing
Software management, hardware imaging and refreshment, and BYOD (the “edge devices”) are not only cost containment strategies, they can be key business differentiators. By ensuring anytime, anywhere access, executives, account managers, and technicians are able to remain connected to the information they require. This connectivity introduces a multitude of devices that must be managed, utilized, and, in some cases, transported. And that introduces the problem of multiple versions. Licensing all these different devices introduces excess cost. Desktop virtualization eases these […]
WebLogic: Oracle updates for cloud usage
Oracle updates Weblogic for cloud usage. New release features.
Using Oracle Database Firewall
We’re all familiar with network firewalls, which prevent unauthorized access to your network from external sources. However, network firewalls don’t protect your databases from malicious attacks, which sometimes come disguised as privileged internal users. Web applications are a major source of data attacks, through stratagems such as SQL Injection, for example. Oracle’s Database Firewall (a product Oracle gained through its acquisition of Secerno, a British firm, in 2010) offers a solid defensive perimeter to monitor and enforce accepted behavior on […]
Knowing your Peak Capacity
One important rule in server licensing (especially in the Microsoft environment) is understanding your peak capacity. Very simply, you must be licensed for the maximum usage of your server – the maximum number of running instances. Even if you, for example, only ever need one instance, but there is a possibility at some point there will be two instances run on that server at the same time – it needs to be licensed for two. The number of instances that […]
Virtualization Licensing Tip: Parallels’ Virtuozzo
When using Parallels’ Virtuozzo on a single physical server, silos are created (running instances that act as the host operating system). Because of this, Virtuozzo is unable to run more than one edition of Windows Server on the physical server. With some products, Microsoft will allow you to run different editions of Server 2008 on different Operating System Environments (OSEs), but in the case of Virtuozzo, you (obviously) cannot take advantage of this. If you are running all instances through […]
Client Access Licenses (CALs) and External Connectors
With most Microsoft servers in a virtualized environment, there are two types of licenses that you can, and in some cases must, acquire – Client Access Licenses (CAL) and External Connectors (EC). The requirements for both are the same – one is required for each device that accesses an instance of server software. This can be on either a physical or virtual server. For example, if you have an employee who needs access to the physical server on some occasions […]
