<br />
Cisco Systems expands its container capabilities as part of its broader multi-cloud initiative and multi-month partnership with Google around hybrid cloud deployment and management.<br />
<br />

<br />
At Cisco's Cisco Live show this week in Barcelona, Cisco officials presented the Cisco Container Platform, a software package based entirely on the open source Kubernetes container orchestration platform.<br />
<br />
The measure adds to Cisco's previous container efforts, including the partnership announced nearly a year ago with the Docker Container Provider, which allows containers to be placed in Unified Computing System (UCI) devices. ) of the giant. networks.<br />
<br />

The Cisco Container Platform is also a further step in the company's ongoing transition to a software and services provider role, with a focus on subscriptions and recurring revenue rather than sales. punctual material.<br />
<br />
"One of the things that makes this new solution so appealing is that it helps customers take advantage of the potential of containers," said Kit Compton, vice president of Cisco's Cloud Platform and Solutions Group. a blog post. the company. "Containers start faster and use less memory than virtual machines, and allow developers to group applications together so they can work in a consistent and predictable environment." Containers can be run anywhere, allowing them to be used anywhere. development and their implementation much easier. "<br />
<br />
All of these attributes have facilitated the rapid adoption of containers by businesses as they migrate to hybrid cloud environments (a mix of public clouds, private clouds, and local data centers) for business operations.<br />
<br />
Kubernetes was born from internal projects that Google IT managers used to manage their internal container environments and has since become the ultimate container orchestration platform in a market that includes Mesos and Docker Swarm.<br />
<br />
According to Tuan Nguyen, <a href="https://testcollection.us/210-451-vce-download.html" target="_blank">Cisco Cloud</a> Center marketing technical engineer, this benefit can be seen in such recent moves as Kubernetes' support for integrating Kubernetes from Apache Mesos and Docker into its Enterprise Edition.<br />
<br />
"In recent years, Docker Swarm, Mesos and Kubernetes have been involved in the duel to bring nirvana orchestration to containerized applications," Nguyen wrote in an article on the company's blog. "Although there are other participants in the scrum and while Mesos has had a longer performance, Kubernetes seems to be taking pole position."<br />
<br />
Cisco managers are striving to position the company as the multiple cloud enabler, the idea that companies will not only be deploying much of their business to private and public clouds, but will include more than one public cloud.<br />
<br />
The provider brings together hardware and software products, as well as services to help customers from the moment they begin to plan their migration to the cloud to implement, manage, and secure applications and data after the transfer. The multi-cloud strategy comes after Cisco abandoned Intercloud's effort last year to become a cloud provider.<br />
<br />
The partnership with Google, announced in October 2017, is to create a cloud-based hybrid offering that will protect the millions of dollars businesses invest in their existing data center infrastructure while creating public cloud access.<br />
<br />
At the same time, customers will be able to decide which workloads to transport in the cloud and which ones remain behind the company's firewall. The hybrid cloud effort includes Google Cloud Platform and technologies such as Apigee and Istio, powered by Google, and Google Kubernetes Engine.<br />
<br />
"The Cisco Container Platform is the Next Step in Integrating Cisco's Open Hybrid Cloud Solution and Google Cloud ... to Our Customers<br />
<br />
Initially, the platform will be available as software in Cisco HyperFlex 3.0 in April. In the summer, it will be available in VM infrastructure, bare-metal systems and in the public cloud. The platform will offer container cluster management capabilities ranging from configuration and orchestration to authentication, monitoring, networking and load balancing.<br />

Not only the image (though it is certainly important), but rather the feelings and associations it causes. Contrary to popular belief, B to B brands are as important as the B to C brands, although executions and objectives are different. Today, Cisco Systems CSCO -1.90% is the launch of a global brand campaign supporting the new positioning of the company.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3iMyrmrZmRzxHJjKUmQZC7PM70CcCrzY7mTY6gUjeRwfmlY1_1hGlDXMFdyRy7kqctjUC-GsDC_bQgDQh3mJXJ9jmTBcc22gSmZnntmrFIKU_WUw5WbHI2MMBE2gduL_3X_eXEmFSVrE/s1600/Never+Been+a+Better.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="223" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3iMyrmrZmRzxHJjKUmQZC7PM70CcCrzY7mTY6gUjeRwfmlY1_1hGlDXMFdyRy7kqctjUC-GsDC_bQgDQh3mJXJ9jmTBcc22gSmZnntmrFIKU_WUw5WbHI2MMBE2gduL_3X_eXEmFSVrE/s400/Never+Been+a+Better.png" width="400" /></a>Cisco Systems is positioned as a "leader and visionary network of global technology of tomorrow." The company knows they need to strongly link the leadership of networking with being a visionary technology. Cisco intends to manage this with a new brand campaign on all channels. After obtaining a careful review of the new brand campaign, aptly titled, "there has never been a better time," I think the right is directional and could take them where they want to go. It is a new era, exciting for the company with new management and new opportunities and I think they finally got the right expression of the brand and performing representative and buyers who want to attract.<br />

<div class="separator" style="clear: both; text-align: left;">
<b>A campaign of "optimism of Technology"</b><br /><br />overall digitization is changing the way the world sees business models, products and services. Cisco Systems believes that if the technology can be an interrupt controller, but also turnkey solutions in his words, by connecting all they can "do it all." There may be terrible things happening everywhere, but Cisco wants to show how technology can have a positive impact on the world, using an optimistic tone. Millennials like that and I do not think this will alienate others.<br /><br />Cisco new brand campaign focuses on a wide range of examples of real-world customer stories of how Cisco technology is changing and improving lives, industry people and, some cases, whole countries.</div>

<br />
Which two functions are associated with a voice gateway? (Choose two.)<br />
<br />
A. Switches voice channels between connected analog and digital voice circuits<br />
B. Provides voice-messaging services to connected analog and digital voice circuits<br />
C. Interconnects two logically separate VoIP networks<br />
D. Negotiates endpoint capabilities<br />
E. Controls opening and closing of logical channels that are used to carry media streams<br />
<br />
<b>Answer: A,E</b><br />
<b>Explanation:</b><br />
The basic function of a gateway is to translate between different types of networks. In a VoIP environment, voice gateways are the interface between a VoIP network and the public switched telephone network (PSTN), a private branch exchange (PBX), or analog devices such as fax machines. In its simplest form, a voice gateway has an IP interface and a legacy telephone interface, and it handles the many tasks involved in translating between transmission formats and protocols. The gateway allows communication between the two networks by performing tasks such as Interfacing with the IP network and the PSTN or PBX, Supporting IP call control protocols, Performing call setup and teardown for calls between the VoIP and PSTN networks by terminating and reoriginating the call media and signaling, Providing supplementary services, such as call hold and transfer, Relaying dual tone multifrequency (DTMF) tones, Supporting analog fax and modems over the IP network.Sunnyhttp://www.blogger.com/profile/11309205695279153991noreply@blogger.com0tag:blogger.com,1999:blog-3488606173274505966.post-75521575391598225072015-12-14T23:54:00.000-08:002015-12-14T23:54:19.865-08:00Which dial plan component is responsible for choosing the appropriate path for a call?642-437 Sample Question: 6<br />

<br />
Facebook Inc has enjoyed a good run in the last year. The population has declined slightly since the beginning of the year, but the network has been a powerful force to examine digital circles.Earnings were relatively Spot-On and expenses exceeded a guide, but most of it was spent on research and development including the acquisition of VR Facebook, Oculus Rift. An interesting thing is that while the lines are blurred by Apple Inc. and Google Inc., in terms of what they do and what they create for the mass market.<br />
<br />
However, Facebook could join hardware level in a completely unexpected field. While Oculus is due to release in 2015, the attention of Facebook fell firmly into the network switch area.Facebook revealed in one of his blog encoding is making greater use of modular switches and display an open modular switch -Power known as 6-pack. As a modular switch, all components run and while connected via a network structure, removing any components not adversely affect other units to function optimally.<br />
<br />
The key word here is open source. Facebook is not the first company to walk this path; Google and Amazon.com, Inc. beat her here. Both companies use their own custom hardware including switches to power their hosting services, as well as the interests of cloud computing. However, both the company's technology is well protected by patents and are not free to use. An open modular switch code would benefit not only Facebook, but also allow impart their knowledge of these devices from other companies who want to use a similar configuration.<br />
<br />
The idea is focused on making centers cheaper to Facebook and other Internet-based businesses data, increasing the availability and customization of server resources range. It should become a standard that most companies spend, Facebook could also serve their own interests to have a certain degree of indirect control of how the Internet works and traffic. However, this placed directly on a warpath against Cisco Systems, the leading business network switch Inc.<br />
<br />
This was echoed by Credit Suisse in its research note. The selling party company wrote: We believe the news of Facebook are perhaps the clearest example of interruption slow but sure was heading networking market. This momentum Foundation for Innovation illustrates perhaps open computing future risk of switching commercialization and industry pressure traditional network providers. This supports long-term field of software defined networking (SDN) contraction in gross profit dollars for the industry our vision no matter who wins.<br />
<br />
Credit Suisse also pushed further this as evidence that Cisco exam dumps could outperform the market and justify its $ 20 price target on the basis that the general trend indicates that the scope of revenues and net profit of Cisco would be threatened long term for new market entrants.Facebook, meanwhile, seems to take a page from the book of Google here the use of open source software. Bidness Etc believe that in due time Facebook will try to push their own platform for the masses - to get all the benefits that open source software means in the form of wider support, the cheaper hardware, and optimizations probably points companies start with strong ties to cloud computing.Sunnyhttp://www.blogger.com/profile/11309205695279153991noreply@blogger.com0
