Not because the clouds sound so high, but becauseThe campus network Authentication & Billing system is deployed locally and will sooner or later expose the uncontrollable risks to operation。
Especially in a university environment with 10,000 students, dispersed campuses, complex exports and long-term running of the billing cycle, cloud deployment is almost the only way to get the system.“Five years or more.”Way.
FromSystem structure, active status, long-term maintenanceThree dimensions, directly dissecting the cause.
I. The campus network Authentication & Billing“Instability”It's not often equipment.
Many universities have been misjudged in early projects:
Local deployments can be made possible as long as the authentication and billing servers are robust.
But in real life,The campus network Authentication & Billing system has a problem, 80% not because the server is not performing well, but because the system's state is uncontrollable.。
Typical problems include:
-
Single-point authentication node anomaly, which led to a failure of the whole school login
-
Paying status residual, present“It's offline, but still counting.”
-
The exit shaking caused a large number of users to be misdirected.
-
System upgrades need to be out of service, affecting the entire school network.
These problems are difficult to reveal in small-scale testing environments, but they almost invariably occur once a true university cycle is in place.
The meaning of cloud deployment is essentiallyTo absorb these uncontrollable risks ahead of time from the structural level.。
ii. Campus network Authentication & Billing system on cloudy ends, local only“Implementation”
The mature campus network Authentication & Billing system, with clear delineation of cloud and local duties:
-
Cloudy is responsible for:
-
Authentication Logic
-
Billing engine
-
Session Status Maintenance
-
Policy Calculating
-
Data analysis and audit
-
-
Local equipment is responsible for:
-
Flow forwarding
-
Strategy execution
-
User access control
-
There is a very real benefit to this architecture:
Even if there were problems with equipment in a particular campus, it would not affect the core logic of the system.
This is of great importance to universities.
In the multi-school landscape, local deployment is almost uncontrollable.
In a single school, single-export environment, local deployment can still be achieved.“I barely ran.”。
But once the following scenes are in place:
-
Integrated management of multi-school complexes by the Education Group
-
Main campus + branch
-
Different conditions for exports between campuses
-
The size of the students varies greatly from school to school.
The locally deployed campus network Authentication & Billing system will quickly expose the problem:
-
Account data is not synchronized
-
Cost-keeping complex
-
User cross-school authentication failed
-
The transporter needs frequent manual intervention.
And...Netshell_AUTH_BILLING System for cloud deploymentIt's a button from the beginning.“Multi-school campuses”Designed:
-
The account system is naturally unified.
-
The strategy is on campus.
-
Central Data Storage
-
Managed permissions can be graded
It's not a functional difference, it's...Differences in the starting point of system design。
IV. Long-cycle running of the billing system, most feared“State lost”
The biggest difference between the Authentication & Billing system and the general management system is:
It is not a configuration system, but a state-based system.
Information that the system needs to maintain on an ongoing basis includes:
-
User Online Status
-
Session Start
-
Time/ flow used
-
Terminal Quantity Binding Relationship
Once these statuses are lost on local servers, they are directly triggered:
-
Arithmetic
-
Student complaints
-
Financial reconciliation difficulties
The cloud-based campus network Authentication & Billing system, usually follows:
-
Multi-copy session storage
-
Status Synchronize in Real Time
-
Node level automatically restored
Even if a node is abnormal, the system can.Keep the billing logic going.Not starting from scratch.
V. HOUSE LONGING LEVEL, COLOMBING POSITIONS ARE TO BE EXCESSED“Focus on the net.”Keys
The height of the dormitory wireless environment is, in essence, correct.Exceeding test of the capacity to combine certification and billing systems。
In local deployment patterns, common problems include:
-
Accumulated peak authentication request
-
Delays in response to costing module
-
A lot of users were misdirected.
-
Present.“The entire floor is off the grid.”
The cloud-based campus network Authentication & Billing system can:
-
Dynamic extension of certification processing capacity
-
Session status does not rely on a single node
-
Local devices only have access control.
-
The peak period doesn't lead to linear decline.
This is why the larger the student body, the higher the university, is not a school.The more the cloud deployment has its advantage.。
6. Cloud deployment has reduced the long-term cost of higher education
Many universities are worried at the earliest stages:
Is cloud deployment more expensive?
But in the real cycle, the opposite is true.
The cloud-based campus network Authentication & Billing system can be significantly reduced:
-
Procurement costs for local servers
-
System upgrades to the carrier cost
-
Cost of manual failure recovery
-
Rebuilding costs for multi-school complexes
The government has been working on the issue of the Internet, especially in five or eight years and even longer.Overall ownership costs for cloud deployment are lowerNot higher.
VII. Design trade-offs on cloud-end deployments
NATSHEL_BRAND was not left from the beginning of design of the NATSHEL_AUTH_BILLING system on campus network“Stacker Servers”The route is:
-
Core authentication versus billing logic cloud concentration
-
Light Quantification of local devices
-
Integrated multi-school area management
-
- We're going to do it in a unified fashion.
This is why in the actual university projects:
-
More stability of the system
-
And send more loads.
-
The transport dimensions are clearly less complex.
-
The overall value is higher.
In the field of the campus network Authentication & Billing system,Stable running is the biggest price in the world.。
I'll just say one sentence from a product point of view.
In the real operating environment of higher education:
The campus network Authentication & Billing is not on cloud deployment.
It's not a decision.“Can we use it now?”，
It's...“Can you be steady in three or five years?”。
