Alibaba has a very rich form of business, behind every business there are many corresponding business systems, each business system is distributed in multiple servers. In such a large distributed system architecture, how to allocate resources to the system becomes a major challenge to site reliability (especially in the dual-11):
- How much resources do we need to allocate for each system?
- How can we ensure that our resource allocation results are consistent with our final business expectations?
We do a reasonable allocation of system resources through Capacity Planning and ensure that the results of Capacity Planning are in line with business expectations through Full-link Pressure Test.
From this topic you can learn:
- Capacity Planning methods and how does Alibaba do Capacity Planning exactly
- Technical implements of Full-link Pressure Test which is the most important weapon for site reliability in Alibaba
