System Design

System design

First no limitation

Then enroll the real world:

Horizontal scaling

Vertical Scaling

Load balancer: server farm: increase security

Big data: database partitioning(sharding): key sharding/vertical lookup table

Caching:

Network:Latency, bandwidth, throughput

Asynchronous processing/Queues

Multi thread; map reduce

Scalability

Key considerations

Some pre:

Failures:

Availability:

Reliability:

Read-heavy/write-heavy:

Security:

Map reduce

Do work parallel

uva 11400 - Lighting System Design（动态规划最长上升子序列问题变型）

本题难处好像是在于可以把一些灯泡换成电压更高的灯泡以节省电源的钱 ,所以也才有了对最优方案的探求好的处理方法是按照电压从小到大排序,只能让前面的换成后面的,也就满足了把一些灯泡换成电压更高的灯泡的要求: 一种电压的灯泡,要么不换,要换则应该全换:换,说明用当前的电源不值:而既然不值则应该全部换掉以避免使用当前电源,不然即增加了灯泡费用又没节省电源费用,亏大了... 状态转移详见代码 #include<cstdio> #include<cstring> #include<
