Upgradation #

To improve QPS or CPU usage to handle incremental load, systems evolve to become more complex. Generic steps that are undertaken to improve infrastructure performance are:

• Load Balancer
• Split Services to Clusters
• Split DB by Service
• Optimize DB Operation
  • DB Cache
  • DB Replication (Master-Slave) for Operations (Read-Write)

DB Upgradation #

To further improve DB perfomance, a distributed approach could be utilized. But following items must be considered:

• Sharding
• Paritioning
  • Horizontal Partitioning
  • Vertical Partitioning
• Concurrency
  • Serially
  • Serially Batch
  • Pessimistic Locking
  • Optimistic Locking
• Resource Locking

Service Upgradation #

Some services require more attention than others to manage QPS/CPU usage, leading to 'Scaling':

• Horizontal Scaling
• Vertical Scaling
