NaaS Network This lesson covers Network as a Service (NaaS). NaaS allows for an offsite network and all that is needed is a computer, a connection to an ISP. NaaS has a number of advantages and disadvantages. Advantages include:

  • Less in house management
  • Greater business continuity and backups
  • Powerful resources for less money
  • Scalable

Disadvantages include: - Less control/more security concerns

  • Can cost a lot
  • Connectivity issues

00:04
Lastly, we have network as a service or nass now network as the service is going to provide you with a essentially an offsite network where all we need a narc office. All we need in our headquarters is just essentially
00:18
a computer. A link to our Internet service provider and
00:21
network is a service mass.
00:23
Now, network as a service is going to be in another company, another outsource provider that's going to host our applications, Data's servers, products,
00:34
everything.
00:35
It's our entire network as a service. Now this the pros of this, the pros of hosting that off to somebody else is that we have less in house management. If we're a small shop and we don't want to manage all of our servers and data and DMC and firewall and everything and our Web server and everything,
00:54
then we may want to just pass that on to someone else.
00:58
We may be able, we may say, OK, we're going to save costs. Were going to stay a small shop, but we still want to provide a very professional looking, very professional looking product, a very professional looking website, Good data backups. Good. Ah, good location. Where all our employees can connect in and make these
01:17
pass on these purchases and
01:19
process applications, whichever we're doing whatever our shop is doing. Or maybe our employees air dispersed all over the United States. Maybe we have multiple employees, but they all work from home, and we don't really have one central location where
01:33
we have all of our data going to back going and backing up. And we don't have a large data center where we're keeping all of our data
01:41
in keeping our Web servers. So instead we just use network as a service. And then all of our employees connect into that,
01:49
so it gives us it provides us with less management. Now that could be a good and a bad thing. We may have less hands on control, but less management also means there's less that we really have to worry about. If something goes wrong, then all we have to do is call up our Nass provider and say, Hey, this is your responsibility.
02:07
We're paying you either paper usage or paying per month or per year
02:10
and you need to fix this because it's part of our contract. So there's less actual management that you have to do and say Okay, well, I need to tell this person. I need to tell this manager todo until the person in this department to work on the server here, and if they can't fix it, we may need to bring in a consultant to try to fix it.
02:27
That's all the responsibility of the NASA provider. You just called him up and say It's not working, and they're supposed to fix it
02:31
for your contract agreements.
02:34
We also have increased business continuity and backups, especially if we have a large Nass provider. We're not talking about just, ah small I t company. That is a single business, a single single physical location that's providing us Our network is a service if we're hosting and contacting a large organization to be our network is a service
02:53
that has multiple sites and multiple fail overs.
02:55
Then if our location gets flooded or power goes out and even one of their locations gets flooded or the power goes out and they may have another location where they just fail everything over to. So we have additional business continuity and we also have those backups, so we may have off site data backup. So even if our location burns down
03:15
all these horrible things that can happen,
03:16
huh? Then
03:19
that data is still good because there's multiple backup sites that it may be backed up to, as our network is a service.
03:24
Another pro Is that where it's gonna provide us with scalable? Resource is, and powerful Resource is for less upfront costs than it would cost us.
03:35
Our network is a service provider already has the data center. They already have the backbone, and they have servers. So when we need to use those servers and we need to use these powerful applications to run applications or compile data or provide a service to users,
03:53
we don't have to go out and buy a $10,000 server cluster. In order to perform these high computing powers.
03:59
All we would have to do is utilize this network is a service, say okay, I need a bit more computing power for the next two hours, and then they provide us with that additional computing power, and it provided in it's pennies on the dollar for what it costs us. All they're paying for at this point is the electricity,
04:15
the cooling, the staff and the action and maintenance of the hardware. They've already bought all the hardware,
04:21
so it's more powerful. Resource is for us, and it costs less money because we only need those powerful Resource is for a little bit of time.
04:30
If we need the powerful resource is all the time, Then we may want to re evaluate if we want to use in in house on site servers or if we want to actually utilize network as a service. So we have to evaluate all our environment
04:45
and scalable. So if we're a shop that provides a service that were a shop that provides lawn service and raking and different yard work, and all around the country, um, and we have small offices all over the country and then one small headquarters office.
05:04
So we want to. We use naps in order to manage all the data from all of our different offices,
05:10
and all our different offices need is computers and Internet service provider in a connection to mess. Then we may have a lot more business in the springtime
05:23
mid mid late summer and then around the fall and then winter time, and then during some of the hot parts of the summer or during certain times of year. We have less business. We have less people saving data to the servers. We have less people trying to visit our website and make appointments.
05:40
So we tell our Nass provider okay,
05:43
this month I know I'm gonna use less, so I want you to scale it down. Or maybe our Nash provider does paper usage. Maybe they take the amount of bandwith that our customers are pushing to our servers. They take the amount of data that we're using and saving and accessing throughout the month. And they say Okay, this month, you used
06:00
stop
06:02
$500 worth of our service. So they charge our company $500 for this service. But for us to install servers and a Web server and data backups all across all of our locations all over the country, and to pay a full time I t staff to manage all of those
06:19
would be a lot more expensive than what we just paid torn *** provider.
06:24
So the scale of the scalability oven oven *** service is eyes very powerful is a very useful tool. When we're trying to. We're trying to manage how much we're paying for our service. Our local in house servers costs the same every month, no matter what.
06:40
Um, nah. Service's can change weaken skill that
06:44
now we have the cons. Now, the downside. So our network is a service is we're gonna have less control, and we may even have security concerns. If we're hosting extremely sensitive data. They say we're not a lawn care provider. We maybe we're a dental office. Or maybe we are small or small. Private doctors office. Well,
07:02
we may need to host that data locally because of regulations that state that we keep those medical records secure.
07:10
We may not want we may not be allowed to, or we may not even want to trust our patient Data with a network is a service provider because we're concerned about
07:19
confident patient confidentiality. So those security concerns do come into play because we don't necessarily want a patient. If we're have a dot our doctors saving patient records to our servers, we want those servers to be in house. We want our technicians to be able to secure those servers
07:39
encrypted files
07:40
and not be sending those files over the Internet because it increases the attack surface for people potentially trying to steal those records or even employees of the Nash service, potentially tryingto look at those records. So we need to take control and security concerns into account.
07:56
And it does cost.
07:58
So say, we're a very, very small, very, very small firm. Then we may not want to pass. We may not want to utilize. Network is a service because the month to month rates, just the base rates of $200 a month, plus additional usage fees may be too much for us. So we may want to just utilize our own in house options.
08:18
And then there's connective ity. Issues with Network is a service. If our Internet service provider data goes out, then our connection to our Nass provider goes out as well. We can't access our local data. We can't access our customer data. So even if someone comes in and says, Hey, I mean Zach, I need to access my appointments. I need to view
08:37
my records. Then we say, Well, we can't
08:39
because our our Internet service provider connection is down. Our Nass are nasty providers down so we can access that data if we have our own in house servers, even if our Internet connections down will. Still we still are able to access our local data because we have that save locally. So
08:58
those connective ity issues also come into play when we're evaluating if we want to host our own or if we want to use network as a service.
09:05
So we have our example of our Nass set up here. We have our headquarters office,
09:13
we have our buyer, and we have Our network is a service.
09:18
So all that we need for our headquarters office or all that we would need for additional field offices
09:26
is a connection to the Internet
09:28
and
09:30
a computer.
09:31
So we have our field offices well,
09:35
so all we need in order to save data to servers and or to run our applications or to run our Web servers in order to do everything that we would need for our network
09:46
is have
09:48
computers and an Internet connection.
09:52
Everything else is hosted by our network is a service. They may host our VP and capabilities. They may, they may manage that, and they may host our field offices trying to VPN into our headquarters when they're actually BP Inning and connecting to our local data here at the NASA, they may manage our Web server. They may manage
10:11
they may save are data backups and all of our
10:13
applications and everything that we host for our customers. So they are hosting everything there are hosting our entire network. Aside from our simple Internet connection, they manage everything else,
10:26
and our Nass doesn't just doesn't just provide that for us. They have multiple other companies on the on their other servers in their data center that they're also managing.
10:35
That's why they're able to do everything for a lot cheaper than we would be able to do. Do it because they're already hosting the huge data centers. And when you buy in bulk, you're going to get discounts. So if we bought one server than we'd be paying maybe 2 to $3000 for that one server. But if
10:56
these are network is a service provider,
10:58
buy servers that are five times as powerful, and they buy 50 of those servers that are five times as powerful, then they may not be paying $15,000 a server they may don't be only be paying $10,000 per server for a server that's 5000. That's
11:15
five times as powerful as our $3000 server. They're getting three times.
11:20
They're getting three times the power for just a little bit more. Or they're getting five times the power for just three times the money, little over three times the money. So per server.
11:31
So they have huge data centers that they're paying pennies on the dollar for what we're what we would pay for servers or resource is
11:39
so they're they're hosting multiple different cos they're They're hosting multiple different companies. Network connections, VP and connections,
11:48
Web servers. Diem. Seize all of that. And
11:52
this isn't like an Internet service provider. Don't confuse Nass with an Internet service provider. Our Internet service provider
12:01
is simply who provides us connective ity to the Internet. So our Internet service provider Horizon Comcast they're going to be who drops us a line and allows us to connect to the Internet.
12:13
And then our Nass provider is going to provide us with all the new intern network internals. It's like we stripped out on. It's like we stripped out our network. We stripped out all our servers. We stripped out all of our data backups and our VP and capabilities that we put him in a different building and then just connect to that building with the Internet. Except we don't manage that building. Another company manages that building.
12:33
So if our buyer needs to visit our Web server or they need to access some of their data, they don't connect to us.
12:41
They connect an ***
12:43
our nests,
12:45
and it's it's transparent that when they go to the website, they go to www dot our website dot com, www dot bob's lawn service dot com. They don't go to our NASA's website. They go to our website and then it just looks completely transparent for our buyer. So
13:03
that's how are now. That's how network is the service works.
13:07
That's what networks as a service does for us and when we're evaluating, if we want to utilize network is a service, we need to take our environment into consideration. We need to take our data and what we're using and how much were using into consideration into our and our pros and cons,
13:24
and when we're determining if we want to utilize network is a service or if you want to keep all of that house.
13:30
So thank you for joining us here today at cyber dot i t. Today we talked about different virtual network components. Everything from virtual servers and virtual switches to network as a service and different virtual PBX is so. Hopefully this information will help you to better evaluate your networks and determine
13:48
what virtual appliances may be useful in your situation.
13:52
Whether network is a service would be a good thing to consider for your environment or whether virtual izing some of your servers will be useful and will be more cost effective in your environment. So take all these considerations into effect. Take that this knowledge and apply it to your own networks,
14:09
and hopefully we'll see here next time on cyber identity.
