Start the first mass deployment of Openstack (soft infrastructure services based on free)

Bah, not the first, but the first to be done in a couple of well-known companies (eBay, PayPal), and at the level of several tens of thousands of servers simultaneously.

We started ..
The enterprise-wide success of free software comes primarily from two sources:
- Be technically capable and viable as the soft option owner.- Be Free to use, having no license cost.
Spinning fine on TCOThe TCO (Total Cost of Ownership, TCO) includes several costs more than a license of the software (the administrators pagás will you install / manage the software for example), however given an infrastructure large enough, licenses the cost becomes much larger portion in the TCO than usual in smaller infrastructure.
In companies like PayPal and Ebay, with around 80,000 servers, the cost to pay for soft licenses will necessarily be quite high for the number of servers.
So when there is a - any - Free soft option, technically reliable, companies with large infrastructure - and a couple of important notions of finding a good balance vs. resource investment. yield savings in license purchase - to implement projects quickly start and stop paying licenses, when at that time there is - or would be - essential to.
The news below comments as PayPal and Ebay started a pilot project 10,000 migrating servers from VMware to OpenStack, with the possible idea - if all goes well - 80,000 migrating servers at some point and stop paying licenses for the use of soft virtualization.
As we walk with the TCO over hereIt is important to emphasize something, given the typical TCO, businesses / organizations seek to always have the least amount of IT specialist staff (which themselves on a common minimum, usually a team of 4 to 6 people), and VMware warrants that can manage a large virtual infrastructure - say, 10-50 physical nodes, with 20-100 virtual machines - with minimal staff and for staff fairly reasonable cost (since it is a market standard, many IT professionals have today certain management skills in VMware, and still hiring outside specialists also higher level entails stole. exceptionally high cost, as if it would be - probably - see complex software with few options of consulting).
So not many companies / organizations are even looking to replace their existing time solutions based on VMware (however expensive they are), including something similar can be said of other options already implemented (Hyper-V, Xen, KVM, etc..) .
And for organizations that are looking to leave sometime Vmware (so expensive it is just now), there are other commercial options extremely viable (and very sought after, in my opinion):
- From the technical (skills reused because the notions of configuration / management are similar to those found in Vmware), and- Since the economic (free hypervisors, or included with the operating system license, additional tools available and reasonably priced: centralized managers, some appliance such as antivirus software and virtualized networking, etc..) Highlighted in particular: Windows Server 2012 ( Hyper-V), RHEL and SLES (KVM and Xen), Citrix (Xen).
Close, not yet, but ...In other words, it is a very good sign starting Openstack massive deployments outside of existing, which was limited almost exclusively to cloud providers infrastructure (IASS): Rackspace, HP, etc.. But there is still some time to see OpenStack competing head to head the typical market - in Argentina, for example - with other offers infrastructure virtualization software, such as today when considering a server OS and compared RHEL, SLES, Windows Server, etc..
Sure, the pioneers who have enough on their computers IT skillset to anticipate, will have the potential for much faster approach to implement virtual infrastructure based on free software, with the many benefits that stole. have: not having to budget tens of thousands of U $ S of cost re-licensing in five-year cycles, and that budget to spend on other needs of IT and / or business / organization.

FORUMS ADMINISTRATOR TO COMMUNITY MANAGER
First, we must understand that a forum is created to obtain opinions on
a particular topic; has a general theme that guides each proposed specific debate. An online forum allows the administrator to define multiple subforums site on a single platform, which act as containers starting discussions users.
Of course, other users can answer and begun in discussions or start a new, as they see fit. Internet forums can be classified into those requiring register to participate and those which can provide anonymously.
In the first type, users choose a nickname, which will associate a password and probably an email to confirm your desire to join the forum. Typically, members have certain advantages, like being able to customize the appearance of the site, posts and profiles.
Some users could obtain privileges in the forum, and then they are called moderators.
These privileges may include the ability to modify messages outside, move or delete discussions, and other mechanisms designed to keep the cordial and friendly (regulations designated by the administrator).
One of the main features of Forums is that we do not know many facts
on the "forum user" (a person who participates in it). Generally, simply enroll providing a nickname (alias, nickname, username) and an e-mail, which, inclusive, may have been created for the sole purpose of participating in a forum and keep total anonymity.
Now we define quite precisely the forum, we are able to understand the
assertion of the title of this section. That is, the passage of the Community Forum Manager Manager.
As a first step, the administrator is circumscribed to this area, while community members, together or separately, may be interacting in other Spanish services without the administrator knows or somehow part. From this point of view, the claim that is made is that the forum can be part of the community, but not the community.
The forums have been very useful before the advent of social networks, and we highlight the advantage they had in terms of management participation and the possibilities of centralization on particular topics. But is it correct to speak in past Forums? Probably the reader to participate in one or more and is in total disagreement with the verb tense used, but it is undeniable that participation has declined markedly, and at the time of creating communities, forums should not be the first alternative that comes to mind to a Community Manager.
Today, we can create our own social network, using free tools
are offered on the Web or other more professional, while not free, are priced
more accessible, such as Ning.
The big difference, then, between a manager and discussion forums Community
Manager is that the former is responsible for that area only, while the CM can be an administrator manage parallel forums and all other areas where you think you are your community ..

HA, DRS, VMotion and Storage VMotion

We will analyze the most powerful tools VMware infrastructure d.

VMotion
VMotion is an essential tool in the virtual infrastructure, which basically allows moving a virtual server from one node to another ESXI.
This option is really interesting because, to use, we will have no loss of service connection or drop the move equipment. This is because the file system using the ESXi, called VMFS.

Once you configure your network for VMotion, we do a test migration. Migration can be hot or cold, that is, with the server on or off.

VMotion is essential to create dynamic datacenters and automated. Now you can perform the maintenance of physical hardware if nafectar business continuity in any respect. It is a technology of 2004 or so, meaning that, at the time of writing, is a development of more than 8 years.
To connect the nodes to the storage and use VMotion, you can connect from a SAN (Storage Area Network) fiber, also supports compratibilidad with NAS (Network Attached Storage) and SAN iSCSI storage systems that are economic.
Migration tasks have priorities and can be scheduled to be performed at a certain time of day. Because we could have a problem if you move a virtual server when you have to move for some reason.
Suppose we are performing a configuration task uan NIC in a node, and an administrator puts a virtual server with VMotion destination node that we are fixing. Could lose the service and business continuity. To do this, the console has a view of all the tasks performed in vCenter.
