CloudConnect 云计算大会 China 2016 How To Build A Stable And Robust Base For a “Cloud” Doctor Cheng Liang Pengyun Network Technology

1. How To Build A Stable And
Robust Base
For a “Cloud”
Doctor Cheng Liang
Pengyun Network Technology

2. Historical Background and Cloud Trends
• Overturn of traditional business
models
• The transactional businesses based
on the Internet or mobile terminals
have grown exponentially
• The requirements for user
experience are higher
– Available at anytime
– Smooth accesses
– Comprehensive functions
– Safe and Reliable

3. Imperative Cloud Transition
• The challenges and opportunities brought by
"Internet+" force the transition form
traditional data centers to cloud computing
• Objects hosted by the cloud platform:
– New business system
– Incremental IT
– The transition of inventory IT
• Hot spots of construction: private clouds and
industrial clouds

5. Traditional StorageVSCloud Storage
Procurement Costs
High-cost Dedicated Hardware Low-cost Universal Hardware
The higher requirements, the more
expensive
Non-universal, poor resource
utilization
Bound to vendors
lower cost, but higher capacity
Universal hardware, high utilization,
on-demand flow
Not bound to hardware vendors, pro-
competitive
Capacity Expansion Costs
High Input, Periodic Capacity
Expansion
Low Input, On-demand Capacity
Expansion
One-time high input, locked funds
Expansion of old equipment, weak
input-output ratio
Bound to vendors, seller's market
on-demand input, optimized allocation of funds
Using mainstream hardware, reasonable input-
output ratio
Not hardware bound to vendors, buyer's market
Operation and Maintenance Costs
Dependent on Mechanical
Operation and Maintenance
Dependent on System's
Intelligent Operation and
MaintenanceUniversal pare parts, high cost
Dedicated teams and technologies, high
staffing cost
Complex operation and maintenance, high
input in professional services
Universal spare parts, low cost
No specific requirements, low staffing cost
Simple operation and maintenance, no
need of professional services
Time Costs
Sudden Construction, Pursue
Opportunities
Ready to Use, Meet
Opportunities
Establishment or expansion takes
a very long period
Complex resource allocation, slow
Fast commissioning
Fast resource allocation

Copy 3
Metadata and User
Data
 Distributed and stored in
the system together
 With multiple copies at
the same time
 After a certain copy is
invalid, the system will
generate a new copy on
the other nodes

18. Cloud Storage
How to Achieve Intelligent
Maintenance-free
Each Storage Node with
Intelligence
 Perceive the health status of
any other nodes
 Automatically work together
with other nodes

19. Best Practices of Cloud
Storage Architecture
 Share Nothing(purely
distributed) architecture,
no central control node
High
Scalability
 Native block storage, the
bottom layer doesn't use file
system or object storage
 Optimize network data path
 Disk IO optimization and
others
High
Performance
 Eliminate single-point failure
 Intelligent failure self-healing,
