Hello again, Are you cloudy? Cuckoo birds. And welcome back to cyber A security in I t Learning Cloud Architecture Foundations. This is module 1.4. Communications is a service and where you can download the new smart shoot telephone app. Not all smart shoe operating systems are supported.
So last time we had an introduction of platform is the service
and we looked agile methods of developing software like scrum. What a fun word. And the software development lifecycle S d. L see, in this video, we're gonna look at how cloud communications is a service or you, CASS, for unified communications is the service has changed the way business is deploy, use and deliver business communications
from no longer being on premise or on Prem
to being powered by the cloud
and how cloud communications has revolutionized this 100 year old telecommunications industry. So if you're ready, let's cloud it up.
Let's get ready to rumble
in the right corner, having almost no wait because he floats in the sky and a record of 12 years of winds and only early in his career losses Our challenger, the cloud in left corner with all the weight of the world because those four post servers and those ups batteries air really heavy
with a lifetime career of winds. But really getting his butt kick lately.
The whining. I mean, reigning world champion on premise. Sorry about that. Now you know why I'm not a sports emcee in just the data nerd. So for almost 100 years, starting with Alexander Graham Bell in his invention of the telephone in 18 79
there's been American Telephone and Telegraph.
The company founded by Bell, its inventor, maintain a monopoly on telephone service in the United States. The goal for almost 100 years was to build the network and delivered wired telephone service to every city town home in rural farmhouse in the U. S. And it worked. It worked great.
The telephone monopoly built the world's largest and most reliable telephone network in the world.
But without competition, the U. S government believed the U. S. Consumer is going to be left without choice and without affordable of alternatives to telecommunication service.
So for most of its 1st 100 years, the U. S. Telephone service was a utility. You were the business you worked at, paid monthly for the privilege of having a telephone or telephone service and for your telephone numbers. But this was all going to change in 1982 when the U. S Justice Department filed in one an antitrust lawsuit against AT and T
before the monopoly break up into the Baby Bell phone system,
the consumer could not own a telephone nor any of its facilities. Everything was a monthly service from the telephone utility. When divestiture finally happened in January 1982 the telephone industry changed overnight. The baby and regional bells were formed, and for the first time, the customer could own their own telephones
and then connect their own equipment to the business, Centrex and office telephone exchanges.
This is the time in history when in business, we start using the term on premise equipment.
In the beginning, premise based telephone platforms were big, clunky, used electronics, and we're messy. Then his technology, advanced through competition in the industry, created the private branch exchange, or PBX, where an organization could grow to tens of thousands of telephones and then for smaller businesses.
The key system, powered by the key service unit, or K, issue,
the first telephones were analog, taking an audio or video signals in translating them into Elektronik pulses. Then came digital telecommunications, where the idea was translated and converted into binary zeroes and ones. And in this world you had separate networks. You had analog phones on one set of wires
and on one telecommunications network and then digital phones run another physical wired network.
And then finally came voice over Internet protocol v O I. P. Now the audio is sampled and then encoded in binary zeroes and ones and then encapsulated into packets with source and destination addresses and then routed on a single Internet Protocol I P Network. Your voice packets are put onto your computer network
rather than having separate voice and data networks.
This is where the terms converged or unified come in V O I. P. With the invention of the Internet, which has created a network without parameters and without borders are what makes the cloud unified. Communications is a service possible
from our previous lectures. Do you remember a couple of disadvantages of on premise solutions and an intern? A couple of the advantages of cloud solutions compared to on Prem? Well, when your solutions or on Prem, you have to procure provisions and stand up all of the computing operating systems,
the applications and the supporting infrastructure to make your on premise solutions run.
And then, of course, she end up spending 4 to 6 times the upfront costs and ongoing maintenance to stay up and running and remain current with Cloud and Unified Communications a service. The cloud stands up and maintains all of my business communications and highly integrated applications, and I only have to pay for it the edge equipment to get to the cloud
and then my end points, which either hard or software telephones for my end users,
UK as makes incredibly complex business communications
So we've come from on premise, separate voice and data networks to fully converged. Voice over i P Protocol Technology UK has also hosts all the premise, service and applications from a unified communication, significantly reducing my hardware software and middleware footprint.
I have a gateway router, an internal network with I P phones and my PCs on prim and everything else is provided and managed by my you cans provider.
Really cool and powerful stuff.
So how does all of this work, remember, are on premise. Equipment is now an edge router. Our land switch, our I P phones and our personal computers. Daisy chain to R I. P phones via a second Ethernet port on the I P telephone. We're still running our normal computer network functions and whatever on premise service servers. We still need to run
our business applications. But at least for now,
all those complex telephone servers have left our premise network and are now pays you use service is from our ucas provider R I p phone. When the first boots up goes through, what is called a sip registration service using session initiated protocol are sip for short. Our phone sip registrar is the UK as cloud sip gateway.
Our phones go through a series of
sink and acknowledge sip negotiations. And then when they agree our phone downloads, it's firm where unique to the cloud provider had becomes part of the UK as telephone platform. Within open up, a Web browser logged in to our cloud dashboard type in the Mac address. That's a unique 48 bit number on my telephone
and then joined the new cloud managed phone to my customer domain.
I make the I P phone part of my company's unique cloud system, separate from the company down the street, who is also using the same cloud provider and then depending on the service, is in my subscription I can use. The service is such a CZ telephone service, voicemail, instant messaging and presence, video conferencing
collaboration, team meetings in spaces and contact Center.
My on premise footprint is a lot smaller. My management responsibility is so much lighter, and I also don't have to be a telephone administrator as well as a network administrator for a day job.
So the UK as market now, we'll have almost reached an amazing 46% of all unified communication phones in the US marketplace. That means that almost 50% of the on premise business peopIe exes and business key telephone systems have gone to the cloud.
The rise of you Can solutions really stems from the unsustainable nature of in house unified communications
and collaboration. UCC deployments from an operations perspective, management and integration top the list of the potential headache inducing qualities of in house unified communications and collaboration with UK as you no longer need to maintain separate platforms for your messaging, chat conferencing,
business APS or contact centers. Instead,
all of these communication and collaboration pieces come packaged neatly together under a single umbrella. So if you would take your new shoe phone app off of vibrate and my hair is trying to call you and tell you that it's time for that learning check
hit pause, write down your answers to these questions and then call us back by spilling out. 86 is a star on your Oxford dress you or from the ladies heel of your choice?
Serena's back when you're all set to go.
So welcome back, Cloud Head. So the U. S Justice Department broke up the telephone monopoly in 1982 and almost 40 years later, 50% of our business communications in the U. S is delivered by the U Can cloud you. CASS can deliver a style tone and call control, voice mail, instant messaging, video and team collaboration, contact center,
business, communication, analytics and a lot more.
You still have a few pieces of on print, but our footprint has gotten a whole lot smaller for UK as I need VoIP phones, a data network with a router and a land switch, and some posted sticky notes to write down your ucas password. Yeah, don't actually do that, by the way,
at Agent 86 a k a. Maxwell, Max Smart and his girlfriend and fellow agent 99 were in the hilarious television comedy called Get Smart
and I Know You Got Smart and got at least one of those questions Correct. Amazing stuff and great job. So in today's lecture, we spent some time talking about how we came from 100 years of telephone monopoly and telephone is utility to. Today's incredibly advanced telephone is a service we no longer have to endure the heavy lifting of standing up all those communications servers and APS
and then integrating them into our environment.
Now we have just tiny prim and using sip protocol. We punt our phone service to our Amazing Ucas provider, and we reviewed the benefits and offerings of unified communications as a service.
So that's it. Cloud heads were done with module one and module to we dig deep into the characteristics unique to cloud service is in the surrounding terminology, like rapid elasticity to bounce are cloudy and users around with.
So on behalf of all of us that the cyber security and I t learning team, we want to wish you and all of the end users on your network very happy packets.
