The Cloud Needs Low Latency
Author: John SheplerThis makes a lot of economic sense. Instead of taking out a bank loan and investing heavily in your server farm and data center, simply sign up with a cloud service provider and pay only for what you use. There is no need to predict how the business will be next year, or even next quarter. You can attack with on-demand cloud services.
it seems very simpleThe solution is deceptively simple. Clean up your current data center or don't set it up in the first place. Rent what you need from a variety of cloud service providers. All it takes is a simple link between your resources and theirs, and no one on the network will know the difference. After all, how do you know if the servers are across the hall or across the country? Few users do anything other than run the software.
web of suspicion
There's an old saying that goes, "On the Internet, a printer on the other side of the country is as close as the one in the next office."
It's okay In fact, it may seem very close or even thousands of kilometers away. Three state servers are similar to the underground server. For some reason, he hesitated. You now have to wait for the system to respond. Worse, doubt looks the other way. You never know exactly how the system will perform from one day to the next.
endless cloud
System performance is attributed to lack of resources. Things tend to slow down a bit when everyone is doing big things at the same time. If you were smart, you tried to finish your work at odd hours before the noisy crowd went to work or lunch. Let someone else handle the traffic. It's the equivalent of car travel time and nothing more fun.
The cloud needed to fix something. The main advantage of cloud data centers is that they have significant resources. Any tenant can increase or decrease the number of servers and storage they use in real time. You should never run out of resources. However, the cloud seems more efficient than before. How is it possible?
wide web problem
A big thing that is often overlooked is that the printer in the next office and across the country is connected to something. This is your WAN network connection. When all your network resources are placed on the LAN, the point is made. Network performance wasn't the only problem, as it had a lot of capacity and short links. The network can be said to be "transparent".
Your network now includes sports LAN connections and wide area connections, except for metro and sports. In fact, they can be very slow. In fact, there is a difference between their local networks and the networks managed by telecommunication service providers. LANs can easily operate to be transparent. This is more difficult and expensive to do over long distances.
What is WAN blocking?
Some technical features define the difference between open and hidden connections. These include bandwidth, latency, jitter and packet loss. You want to increase the first one and decrease the other three.
It's tempting to conclude that slow network performance has little to do with capacity. As you begin to use more of the available bandwidth, you may experience periods of congestion where there are too many packets to send down the line at once. A simple solution? Increase your bandwidth. Increasing the bandwidth by 2x, 3x, or 10x should solve the problem immediately... or should it?
One problem that increasing bandwidth cannot solve is latency. This is the time packets take to travel through the network. We believe that moving electricity from source to destination is instantaneous. Locally, that's a pretty good estimate. But once off campus, even the speed of light might not be enough.
reduce latency
Of course, one way to reduce transmission latency is to reduce distance. Even at the speed of light, you can only travel 300 kilometers per millisecond. It is 10 mSc for 1860 miles. Actually, even that is not possible. In the real world of fiberglass you can see 15-20 milliseconds round trip or at least 40 milliseconds round trip. If you're using a geosynchronous satellite link for part of the journey, it's about a quarter and a half seconds.
Most applications won't cause a delay of more than 40 milliseconds, although half a second will be noticeable and difficult. It is claimed to use terrestrial fiber connection and the shortest possible path to the cloud (on the ground). A point-to-point private line is probably the best bandwidth you can get. With a private managed MPLS network, you can achieve comparable or close performance at a lower cost.
What about the Internet?
Yes, the Internet. Sounds like a good resource. It goes everywhere and connects everyone. Pricing is set per user, making the Internet your affordable solution. Security is definitely an issue, but encryption can actually create tunnels that give you a private network that looks like a private network.
This paradigm focuses on performance rather than security. The Internet is not designed to minimize latency or congestion. Architecture is designed to last. If you lose connectivity between servers, the network will automatically configure itself to repair itself and allow traffic to flow through. Unfortunately, this means that your packages may take multiple routes on different journeys. Specific nodes may experience bottlenecks when overloaded.
Does this mean you won't be able to use the internet to connect to the cloud? Private lines are ideal for high-performance or high-sensitivity real-time and interactive applications. Alternatively, you can settle for a public/private hybrid called DIA or Dedicated Internet Access. They still share a high-performance Internet Core backbone, but connect over a private line that minimizes latency, stuttering, and packet loss during that critical first mile period.
Be better connected to the cloud
There are many cloud connectivity options for most business environments . Review the good and bad costs/performance associated with each, and choose the link you need to set up your cloud connection the way you want it.
