Understanding Lingering Objects in Active Directory and How To’s?

omid.koushki
There are some specific concepts in active directory which may put your environment in trouble if you do not attend to fix them as soon as you notice. One of them is Lingering objects. Defining the meaning of Lingering Objects (LO) is not difficult. Basically if an object in your active directory partitions exist in one or more domain controllers and not exist in the rest of the domain controllers in the same partition. So you may ask yourself how that is possible to have an object in a DC and not having the same object in another DC? So what is the responsibility of replication? Wasn’t it designed in order to have a synchronized AD database in your environment? We are going to cover your questions as well.

Hyper-V 2012R2 vs. vSphere 5.5

omid.koushki

Now that both Microsoft and VMware have officially announced the new released of their virtualization products it’s possible make an homogenous comparison between Hyper-V 2012 R2 (the fourth generation of Hyper-V) and vSphere 5.5.

VMware vSphere 5.5 introduces several news and scalability improvements, on the other side Microsoft Hyper-V 2012 R2 consolidate its features and improve what was already existing in the 2012 version, with a limited (but significant) new features. For example now, finally, some VMware old date features are mainstream also in Hyper-V, like VM hot cloning, hot disk resize (in this case also with the possibility to reduce the size).

Compare Hyperv 3.0 & Vsphere 5.0

omid.koushki

1) Scalablity

To start the comparison, we would choose scalability and  config maximums as these are the important aspects to look for while choosing the platform for your cloud.

Microsoft Windows 2012 RC’s Hyper-V 3.0 seems to be promising on scalability than VMware vSphere 5.0. The maximum supported clustered nodes increased to 64 with increase in support of running VM’s i.e 4000 VM’s, more logical processors per host and more Physical RAM per host as compared to VMware.

10 most powerful cloud companies

omid.koushki

Virtually every vendor has a cloud story to tell. But here are 10 companies that have distinguished themselves as the leaders in cloud computing, either by being first to market, by offering the broadest and deepest set of cloud services or by taking a leadership role in the cloud revolution. Other articles in this issue of Enterprise Cloud Services:

1. Amazon: The IaaS gold standard

The online retailer came out of nowhere in 2006 to offer up idle compute cycles as a service. Since then, it seems like there’s no market Amazon is unwilling to enter and no competitor it’s unwilling to take on. There’s the market setting Elastic Compute Cloud (EC2). If you’re a third-party provider of cloud services, that’s the platform you need to be compatible with. Over time, Amazon has added multiple cloud storage offerings and is moving into the PaaS market. The company is also selling tablets (Kindle Fire) and challenging Apple and Google in the cloud-based music arena. Continue reading “10 most powerful cloud companies” →

Top 10 Technology Trends for 2013

omid.koushki

What will drive the technology trends for 2013? Analyst firm, Gartner shares their prediction:

Mobile Device Battles
By 2013, mobile phones will overtake PCs as the most common Web access device worldwide and that by 2015 over 80 percent of the handsets sold in mature markets will be smartphones. However, only 20 percent of those handsets are likely to be Windows phones. By 2015 media tablet shipments will reach around 50 percent of laptop shipments and Windows 8 will likely be in third place behind Google’s Android and Apple iOS operating systems.

Windows 8 is Microsoft’s big bet and Windows 8 platform styles should be evaluated to get a better idea of how they might perform in real-world environments as well as how users will respond. Consumerization will mean enterprises won’t be able to force users to give up their iPads or prevent the use of Windows 8 to the extent consumers adopt consumer targeted Windows 8 devices.  Continue reading “Top 10 Technology Trends for 2013” →
