What is a Vpn Connection

Citrix loves to communities. At this Citrix Synergy conference this year we were hosts to teach local Las Vegas middle school and high school classes children of microcontrollers and robotics. With Citrix Octoblu IoT platform, a class of 5th graders an Intel Arduino Power could push to Talk Video walkie-talkie in less than 0 minutes!

At first build a sound Internet of Things (IoT) class to thirty 5th graders teaching a little daunting; However, we expanded the curriculum in four phases, the demonstrated success at every step of the process. This short course learned the basics in hardware and software in small (but fun) steps

Step 1 :. We brought the children, such as an LED on the Arduino microcontroller and flash to fix it at any speed

Step 2 :. Next we taught the children how a button to the LED light to join them there to turn on and off. As you can tell from the photo below, the children enjoyed their services

Step 3: shifted Next we Software and taught the children how the laptop to snap camera to activate on WebRTC photos of the person

key step 4 :. , the last part of the exercise was to networking all the chats in a single space video chat with Octoblu.

Mission Accomplished! the roomful 5th Grader was much press los chat with entertainment while with their friends micro controller buttons to communicate with each other!

We want a giant give THANK to Intel for the Arduino donate 101 (Curie powered) microcontrollers and Dell for us, the Chromebooks to use borrowing during this event. We would like to thank also to Las Vegas for flying Luis Montes to teach this class and help all the CTPs and volunteers for us to make this event a great success!

Last (but not least), a big thank you to Jo Moskowitz for making this event possible!

A mobile-ready Campus fosters innovative and flexible learning and provides a competitive advantage. Students are increasingly using mobile technology during the college search process. After enrollment of today's college students only require not have access to campus services on their mobile devices -. It require

In the K-12 arena, a study found that more than half of parents believe schools should make more use of mobile devices in education. And after EdTech "[mobile] technology allows educators from traditional lectures to move away and focus more on individual and project-based through the use of cloud applications learning (Google Apps for Education, for example) and online content".

with Citrix Prepping for Mobility

Many school systems have solutions Citrix and Universities implemented for education to support their mobility goals. Citrix technologies allow students, faculty and staff, the applications for access to data and services they need, from any location, device or network with high security and a seamless experience.

To the greatest value of Citrix software to receive, or any technology solution, IT teams need the right expertise and references. But how can an overburdened IT department, bridge the knowledge gap until existing staff have time to get speed, or new employees can be brought in?

And speaking of new hires, current IT staff shortages may make it difficult to find qualified staff to manage and support a Citrix infrastructure.

Dire straits for staff

The EDUCAUSE list of top "set IT staff and retention" 10 IT topics for 2016 ranked as # 4 and indicated partly "... many institutions reduce budgets and services or flat lining compensation at a time when new iT staff are essential to meet institutional goals and an improved labor market for iT professionals can make it hard to keep up and potential employees existing "

In this difficult situation, schools, colleges and universities to the question will need a new answer:" how can we make our Citrix environment to optimize as soon as possible "

DOWNLOAD OVERVIEW

No matter who you talk to, you will hear that this year's Citrix Synergy was one for the record books. Our metrics show it, we could feel it, but most importantly, so many of you have told us how much you loved this year's conference. And the reason you loved it comes down to one word ... customers.

was this year all about the customer, of the people who attended to the people who spoke.

All our feedback and research told us you wanted to hear from your colleagues. So, of inspirational keynotes to hands-on innovation showcases, in-depth training and outbreaks to secure IT leaders shared real stories of the company to optimize the network, the mobilization of the workforce -. And the business digitization

customers as Paul McEwen, CIO and Group Head of Infrastructure Services at UBS.

Paul accompanied me on the main stage during our day 2 General Session to describe how UBS Unified Communications supplied with Citrix electricity. It is an exciting story .: provide a global financial company Skype for companies to 80 percent of the 100,000-person staff, delivered by XenApp and XenDesktop The result? , A dramatic increase in employee productivity, agility and efficiency

There is no better validation of the value of Citrix solutions as an innovative customer - in their own words. See for yourself.

It's awesome to have customers like Paul, the slide Citrix to be the best that we can be ,

And their transformational journey is just beginning.

We would like about your to hear travel. Feel free to share it below.

P.S. I use the word "awesome" more than a dozen times on stage during day 2 General. The Twitter-sphere noticed - and I meant it! 😉

Bill Burley says "awesome" 20+ times during keynote. This means that Citrix must be ... Awesome! #CitrixSynergy

asked a few customers recently to protect, if we can help reduce the cost of application security in the cloud. already understand these organizations that although cloud providers like AWS offer fairly good protection against generic network level attacks, the accessible Internet hosted applications on cloud platforms to narrow attacks remain fully susceptible to a legitimate application traffic masquerade. It is therefore essential to identify a web application firewall in front of these applications for deployment in an intelligent way and block all malicious traffic.

standardized My Account on Imperva WAF as their choice, so I took the following analysis to determine how much we could save instead using NetScaler VPX. Here are my results.

---

Is it safe, a, with a powerful WAF engine to replace pure-play WAF product like Imperva NetScaler ADC as one of its many functions?

---

to answer this, I. NSS Labs latent which undertook a study of the various options leading WAF recently NSS confirmed that NetScaler is an effective WAF platform and gave him a "recommended" (Imperva received a "neutral" rating)

. Source: https://www.nsslabs.com/research-advisory/security-value-maps/waf-svm-graphic/

---

NetScaler up to 50% cheaper than on Imperva AWS!

---

. For commercial analysis, I compared the cost of operating Imperva & NetScaler straight from the AWS Marketplace over 6 and 12 months for a number of different traffic loads The results show consistently NetScaler is much cheaper than Imperva, and the savings escalate over time

NetScaler is consistently less expensive than Imperva in AWS -. 6 months

NetScaler at a fraction of the cost of Imperva takes about 12 months or more.

Graphical representation of the total cost per Mbps of application firewall protection makes it crystal clear that NetScaler delivers the best price performance for each flow

comparing cost per mbps -. NetScaler vs. Imperva in AWS over 12 months

---

BYO license provides even greater savings over 10 months or more.

The rule of thumb: if your VPX run for 10 months in AWS or more, you are probably better off buying a perpetual VPX license from Citrix and using the "BYO license" plan option in AWS. 10-11 months is about the crossing point where the achieved hours AWS costs the list price of the perpetual license. Existing Citrix customers entitled to promote discounts on perpetual licenses, which could bring the crossover point forward to 6 months or even earlier

For example, if the available models capable of 100 and 500 Mbps are respectively, and the 500 Mbps costs 3.5x as much as 100 Mbps, we would 3x 100 voting for 300Mbps and 1 500 for 400 Mbps.

now you've probably on XenServer 7 and its cool new features, one of However, this version is is. more than just its feature list - we have also in the fundamentals invested XenServer 7 to make a platform on which we can provide even more innovation, features and improvements over time

Let some one views. the platform and architectural changes we have But before we start with the ceiling of XenServer 7.

let us taken a look at XenServer architecture for a little guidance. The Xen hypervisor project is a "Type 1" hypervisor that runs directly on the hardware. On this we a privileged Linux virtual machine, called "Domain 0" and is based on CentOS running, the tool stack management and API runs, includes drivers for networking and storage I / O, etc., and quite a number of other things.

So what has changed?

Domain 0 Linux version

A significant change in XenServer 7 is the upgrade of the domain 0 around CentOS 5.10 CentOS 07/02/1511 . At the domain 0 Linux environment is NOT provide customers visible features, however, because it most of the server components of XenServer hosts, it is extremely important for the operation of these components, and our ability to add new features that it depend on you. By moving up to date to, but stable and enterprise-class Linux platform we are well XenServer 7 placed to assist in the future, benefit from bug fixes and improvements from the CentOS project view and their upstream provider and Open Source -Communities.

The updated Linux platform also offers opportunities for future features and enhancements that would have been difficult on older CentOS 5 platform or impossible. Coupled with XenServer existing Linux 3.10 kernel, the new platform given us more ways to use Linux filesystems as ext4 as the basis for future XenServer storage functions.

You may wonder why the move to CentOS 7 didn 't automatically mean that XenServer 7 acquired different functions and mechanisms that have happened 7 CentOS as SELinux or XFS file systems. This is because the domain 0 Linux platform a component of the XenServer system (rather than XenServer is an application that runs on Linux), and therefore is closely integrated into the overall system - if we have a upgrade the system components, our first priority is to ensure a like-for-like upgrade that preserves the integrity, functionality, quality, performance and safety of the system. If the new component comes with new mechanisms that did not exist in the older version, we carefully consider whether and how we can these new mechanisms in the XenServer system (eg change from ext3 to XFS would require careful examination for XenServer to integrate, upgrade and use cases rollback and is therefore not a transparent change.) - these additional integrations can be used as the underlying component upgrade in later versions

with the release of XenServer 7.0, we mostly use CentOS 7 as again for-like replacement for CentOS 5 - with new mechanisms in the newer version to be candidates for the integration and use in the following XenServer releases. As with many of the fundamental changes we will talk about in this blog, I would expect to see more of the value of CentOS 7 surface in the customer visible features and improvements over the next few XenServer releases.

Partitioning Layout

Earlier versions of XenServer have a partitioning layout of a primary partition used 4GB consisting (this is the domain 0 Linux environment and XenServer stack hosts which it sits), partition a 4GB backup roll-back after an upgrade, and to allow used as a storage repository for VM disk images the rest of the plate. In preinstalled OEM systems an additional OEM partition can be there.

Although 4GB is more than enough for the XenServer software the same partition for third-party add-on "Extra Packs" is also used, like all host protocols and temporary staging for hotfix files and so on. Even with log rotation and compression are some cases of the file system were to fill because of the volume of log files. Before XenServer 7 there was a mechanism to some mitigations also the total volume of the log files (in addition to the per-file rotation) and for placing the log files on a separate volume in space from the local storage repository loan cap. In XenServer 7 we decided that it was time to move larger partitions and make the log partition a default configuration. This means that we now have:

• 18GB XenServer host control domain (Dom0) partition
• 18GB Backup Partition
• 4GB logged partition
• 1GB swap partition (just in case - we try to avoid using swap)
• 5GB UEFI boot partition

the traditional layout used in cases , 4GB, where the primary hard drive is smaller than the required 46GB can. In cases where older XenServer hosts XenServer update 7, the host will be repartitioned when the local storage repository is empty (as is often the case when shared memory is used). See the installation manual for more details.

Xen hypervisor project

XenServer 7 saw us Xen 4.4 Upgrade (in XenServer 6.5) 4.6 to XEN also contains the new contents of Xen 4.5. This brought a number of useful mechanisms fixes and enhancements, including virtual memory event subsystem and support introspection with Intel EPT and AMD RVI , the part of XenServer of Direct Investigate APIs form lets you agentless antimalware VM introspection. The upgrade provided a new framework for the management, the CPU functions are exposed to VMs - a prerequisite for the VMs allow the benefits of CPUs take instructions ahead as AVX2 while allowing downward leveling of feature sets VMs allow, be moved between differential CPU generations the basics and options.

with the domain 0 CentOS 7 Upgrade There are a number of new mechanisms of the updated Xen hypervisor XenServer that are not used today brings for future features, but offer. Some areas of particular interest are extensions Xen Security Modules (XSM) - mandatory access control framework in the style of SELinux, albeit on the hypervisor instead OS layer; Support for vTPM 2.0 , possibly a chain of trust from hardware TXT / TPM boats permitted right by virtual machines on trusted boot; and PVH virtualization mode - a step towards unifying Xen two modes, PV and HVM in order to reduce the complexity and the advantages of both modes at the same time receive

Xen 4.5 and 4.6 also. brought a number of performance enhancements - to http://xenserver.org/ cause an eye out for a series of blog posts from XenServer Performance Jonathan Davies, who in a number of performance and scalability enhancements in XenServer 7.

Active Directory integration

Because Active Directory support was introduced in XenServer 5.5, we have the Also used tools with AD server to connect to. In XenServer 7 we update these tools to a newer PowerBroker Identity Services (PBIS) packages that provides better support for complex corporate structures and better credential caching along with a number of other compatibility, performance, scalability and stability improvements , used

using the IOMMU

XenServer physical I / O device driver in the domain 0 kernel and must often allocate memory in DMA transactions to hardware devices such as RAID controller or network interface. adds a layer of indirection in memory allocation (compared to a bare-metal operating system) and thus the domain 0 view of the accumulator to have a hypervisor, is different from the view of the memory of the physical device. For individual memory pages, this is easy with a simple translation but DMAs from more than one side adjacent to the size of the physical storage area and therefore can not be a single translation of the start address, is not possible, treated. The simplest solution for this is to pass all DMA transactions by memory from a memory pool with a picture with the host physical memory 1-to-1. This pool is known as software I / O Translation Lookaside Buffer (SWIOTLB) or bounce buffer . However, this adds a memory copy to each DMA, increasing latency and lowering power; and it risks DMA failures when the SWIOTLB is exhausted or fragmented

XenServer 7 avoids these disadvantages by using (if possible) the hardware of IOMMU -. can access a device, the physical device memory using virtual addresses rather than physical addresses and therefore, the same memory allocation is used as the domain 0th This means that, even if the physical memory for the DMA is not connected, the device on / off her DMA as if it, exactly the same address as it was given by the Domain-0 device driver. This avoids the SWIOTLB memory copy and the pool exhaustion problem leads to better performance and reliability.

virtualized I / O

We have just been changes, both our storage and network I / O data paths to increase performance. See Jonathan Davies' performance blog series for more on this topic.

API extensibility

The XenServer tool stack and API consists mainly of the XAPI daemon. XAPI is the API endpoint and almost all API implementations are handled directly by him. 7 XenServer provides an internal API extensibility framework, the new API makes calls added and their implementation are handled by separate executables within the XenServer Domain 0 environment. The aim is a modular, extensible tool stack to enable, where new functionality can be added with the reconstruction XAPI itself.

And more ...

• The Open Virtual Switch (OVS) has been updated to version 2.3.2 - stable and proven release
• to create to manage the use of Linux cgroups resources 0 within domain better response under load
• many internal refactoring of XAPI tool stack to make it easier to add new features

Finally, there are plenty more cool stuff to the ceiling of XenServer 7, as you might think. This is one of the largest and best XenServer releases we've ever done, and it will form the basis of a stream of new features, improvements and enhancements over many publications. Stay tuned ...

The children of today seem to know exactly how they will contribute to the world. An online search of "What do you want to be when you grow up?" Networks many very normative answers - "a Lego Master", "a fight Ninja", "a spider who is learning how to turn" and "one", just to name a positive "rapper" a few. There are even multipotentialites, dreaming those to combine their career several different skills and creative pursuits.

In a time when aspiring doctors, lawyers and firemen governed, our colleague Ben Wilson, may have been before the curve.

"My mother was a teacher, so I grew the review of the civil service," he says, "but I also had an interest in the economy." After college, a stint at an entrepreneurial medical technology companies Ben led to an important realization. "If I worked in certain areas of the US health care industry," he explains, "I could have a career that both public service bridged and business. That was convincing."

Today, has as Citrix Healthcare Evangelist, Ben found himself on the bridge between the world of business, healthcare and technology. perfect Twenty years in the healthcare industry, an MBA and a master's degree in public health from UC Berkeley position him questions about meaningful use and MACRA answer. Here is the first of two blog posts, he touch on the basics of MACRA, its measurements, and its potential for popularity. In the second it is a little deeper and make the connection between MACRA and Citrix dive. Here's what he had to say:

Kathy: Considering what the press had lately, as you can see meaningful use change

Ben ?: meaningful use, ACOs and shared savings program have been implemented to improve the introduction of electronic medical records (EMR) to promote health care in the United States. Now that the goal has largely been achieved, there is an effort underway to combine these programs under a single simpler program. Medicare access and CHIP Reauthorization Act of 2015, which as MACRA known

It is expected that MACRA is in January at the heart of it 2017 something called Merit-based incentive payment system, or MIPS is implemented. With MIPS provider is paid, as they provide care to use a simpler set of results. The focus of the program is to do three things :. Healthcare delivery patient-centered, make practical and easier to

The Department of Health and Human Services instigated this change. The Center for Medicare / Medicaid Services (CMS) is a part of this group. CMS is the unit that administers Medicare

It is important that the program MACRA to note focuses on the doctors that provide Medicare services in the United States -. Instead of looking at hospitals or on Medicaid itself. This is a big part of the remuneration which forms the government, for all in the US, around 40% of spending accounts

Kathy .: Tell me more about how things are measured

Ben :. Doctors will now be measured against a simple set of results. The big difference between meaningful use and MACRA is that MACRA be focused not only on the use of electronic medical records (EMR). (Remember, though, that a meaningful $ 72,000 per year put paid to doctors if they met criteria EMRs in a meaningful manner with respect to the use. However, it is not improvement measure in the provision of care, patient satisfaction or cost reductions.)

Kathy: There do not measure danger either directly

Ben: "properly Meaningful use was completely focused on the adoption of electronic records. (EMR) Today, 75% of doctors -. and almost every hospital in the United States -. have an EHR in place that the goal has been reached

Well, things are still have a step to go -.. to improvements in care and cost reductions with those electronic medical records Now, about 50% of the measures for the results will be based on quality. There is also a cost reduction component to quality focused. Finally, only 10% [of the measurements] is based on whether doctors are using technology in a good way.

exchange of data with other organizations and care coordination between the organizations will also be crucial. This will be good for the healthcare IT world because meaningful use stifled innovation. It commoditized electronic medical records because the provider had to meet certain criteria in terms of what could do their medical records, but they had no incentive beyond that to go in terms of how the records were used.

What's more, electronic medical records software developers had to improve no incentive to build new features or practices to reduce costs. Software companies have not put resources in innovation and to examine the creation or new ways to use their software. Nor do not necessarily think about new ways to improve patient outcomes. This is set to change that physicians incentives to find tools that will help them to improve delivery of care and reduce costs

Kathy:.? Do you think doctors will MACRA embrace

Ben: Because it is easier and there is less coverage than was involved with Meaningful Use, MACRA is less prescriptive with respect thereto how doctors must meet objectives. Doctors will love it compared to Meaningful Use. They really had to get reimbursement or incentives in the past five years ext. The American Medical Association has played a major role in the original draft of the regulations. Already the instigator of MACRA feedback from healthcare providers have received that this very positive.

There was a lot of scope of Meaningful Use by the provider community that was neither positive for administration nor for HHS. The MACRA team tried very hard, these providers to make friendly. They also have to get a lot of effort expended feedback on the way and integrate that. An insight into the development of policies

MACRA gives physicians more freedom. It allows them to choose a subset of quality measures on which they wish to be evaluated. Doctors can use the measurements that best highlight the improvements they have made - based on their particular specialties or to specific types of practice that they manage. For example, a country doctor has used various problems and challenges in patients as an urban doctor.

The fact that doctors have this ability to select the specific measurement, in which they achieved allows for a much more individualized program for each doctor. It makes it much more likely that clinicians be successful in meeting the requirements of MACRA program. And most importantly, it gives them the freedom to innovate and design as to better serve to their patients.

There are much more to learn about MACRA. Pay attention to the second blog in this series. It is coming soon!
