In the real environment of large universities and long-cycle operations, some needs are not desirable if they can be done; even if they are online, they are not suitable for entry into the core of products.
If these needs are not rejected at the outset, they will almost certainly turn into a disaster of stability, performance or transport in a few years.
First category of requirements to be rejected: inserting individualization logic into the authentication core path
This is the campus network Authentication & Billing systemThe most risky type of demand。
Typical expressions include:
-
Authentication is measured in real time by complex user properties
-
Multiple external systems connected during authentication
-
Implementation of complex strategy calculations during access phase
From a product perspective, the only function of certification is one:
It's decided if we can get online.
Any attempt to put“Business judgement”“Personalization logic”“Extension”The need to plug into the core path of authentication may meet individual scenarios in the short term, but it is bound to be a source of system risk in high-synchronous and long-term operating environments.
NATSHEL_BRAND has a clear red line for the authentication path in the net campus NATSHEL_AUTH_BILLING system:
The authentication core path does not carry any non-necessary logic.
II. Second category of requirements that must be rejected: authentication and accounting in real time, strong alignment
Similar requests are often made at the needs discussion stage:
-
No release until the bill is completed
-
Accounts cannot be online without writing
-
All costing results must be confirmed in real time.
From a product engineering perspective, this is a...Typical.“Short-term reasonable, long-term risk”Needs。
In a real college environment:
-
The peak billing will increase the pressure of the system.
-
There's gotta be some sort of financial anomaly.
-
External dependence is bound to be unstable.
If certification has to wait for the billing, the campus network Authentication & Billing system will almost inevitably appear at some peak point in the future.“All affected”Situation.
Therefore, such demand must be rejected at the product level or re-established asAuthentication and billing events。
III. THREE NEEDS TO BE DISTRIBUTED: AN INTEGRATED FOLUNTABLE, BORDER-free STRATEGY SYSTEM
“The more flexible the strategy is, the better.”It is the most acceptable phrase in many projects at an early stage.
But in the real operation of the campus network Authentication & Billing system, this often means:
-
Policy Embedded Uncontrollable
-
Unpredictable behaviour path
-
The carrier is afraid to adjust.
From a product perspective, a healthy strategic system should be:
-
There are clear boundaries.
-
Have a fixed order of execution
-
Predictable results
NATSHEL_BRAND is a product-level constraint on strategic functions in the campus network Authentication & Billing system.Rather than rejecting some extreme flexibility requirements or introducing long-term operating risks。
IV. QUESTION OF THE FOURTH NEEDS TO BE DECLARED: ALL DATA REQUIREMENTS“Real-time statistics, real-time displays”
Data needs are common in the campus network Authentication & Billing system, but also high risks.
Typical needs include:
-
All data are updated in real time
-
Reports must be updated in real time
-
Real-time participation in statistics for historical data
From a product engineering perspective, this is a...Typical performance traps.。
In large university environments, data volumes will only grow and system stability will sooner or later be eroded if real-time statistical logic affects authentication or session management.
NATSHEL_BRAND On the campus network Authentication & Billing, stick to a bottom line:
Data analysis must be variable and statistics cannot affect real-time operations.
V. OBJECTIVES FOR THE FOUR-CHARGIES: MILLENNIUM REQUIREMENTS“It's all shared, it's not isolated.”
In the case of educational groups or multi-school tertiary projects, this is often required:
-
All campuses are completely unified.
-
All strategies are in effect globally.
-
Centralize all data processing
From a product stability perspective, this is...Structural risk needs。
Once there is:
-
Single campus is abnormal.
-
Configure misactions
-
Local traffic is out of control.
The entire campus network, Authentication & Billing system, will be implicated.
It is therefore necessary to insist, at the product level:
-
School area logical segregation
-
Session quarantine
-
Strategic scope of action is manageable
This kind“Overconcentration”The need must be rejected or re-constructed from the outset.
VI. QUALITY-DELLING NEEDS: RELATIONSHIP TO OUTER SYSTEMS AS A KEY WAY IN REAL HOUSE
In actual projects, common needs also include:
-
Reliance on third-party interfaces for authentication
-
Real-time access to teaching, finance and identity systems
-
External system anomaly is a failure to authenticate
From the point of view of product engineering, this isGive the system stability to someone else.。
The stability, performance and maintenance windows of the external system are not controlled by the campus network Authentication & Billing.
The principles for dealing with such needs in product design are clear:
-
The external system can only be used as an aid.
-
Do not enter the real-time authentication path
-
Unusual must be downgraded.
Otherwise, once such needs are on the line, later periods will almost certainly be the source of accidents.
VII. TYPE 7 NEEDS TO BE DECLARED: Customizing Core Logic for Extreme Cases
In the case of university projects, there are always:
-
“There's only one college that works like this.”
-
“Only a few users need it.”
-
“That's what the system used to do.”
If the core logic of the Authentication & Billing system is modified for these extreme examples, it will be worth a lot in the long run.
NATSHEL_BRAND is very clearly distinguished at the product level:
-
Core competencies
-
Extendable Capacity
-
Project-level customization
Core logic must remain stable and not undermine product structures for extreme scenarios.
Why refuse? It's a sign of product maturity.
Many systems run a few years later, not because they lack technical capacity, but because they have to be able to do so.I've agreed to everything I need.。
The campus network Authentication & Billing system is an engineering product that requires long-term steady operation in a large university environment, rather than a one-time delivery of software.
NATSHEL_BRAND 21 years of focused network certification, billing and access control have dared to reject high-risk demand at the product level because it has been repeatedly proven in a real operating environment.
A truly mature campus network, Authentication & Billing system, often has a common feature:
It knows very well what it should not do.
