01 INTRODUCTION TO SCALABILITY 4
Scalability, Scaling Scalability is The ability of a system (business or technology) to handle increased requests without altering response time. Scaling is The increase or decrease in the capacity of a system by changing the number of allocated processes. 5

02 The AKF Scale Cube 7
AKF scale cube Infinit ite Scale The AKF Scale cube is a model for • defining microservices and scaling technology products, invented in 2007 by AKF partners consulting company. Y- This cube has a 3-dimensional axis • axis represent a unique method of scaling products, processes, and teams. X-axis 8
AKF scale cube X-axis Infinit ite Scale Represents the cloning of services or data such that work can easily be distributed across instances with absolutely no bias. Y-axis Y- Represents the separation of work axis responsibility for an action,also known as service or resource oriented split. Z-axis is Represents the separation of work by customers or requestors. (0,0,0) X-axis Monolithic ic System 9
03 Splitting Applications For Scale 10
Scaling Applications : X- AXIS Cloning/Replications - Clone services or duplicate databases Infinit ite Scale - Use a load balancer Pros : - Easy and fast to implement - Perfect for read only databases Y-axis Cons: - Cost of replication - Doesn't address caching X-axis 11
Scaling Applications : Y - AXIS Split Different Things Infinit ite Scale - Separates into services - Separates into resources Pros : - Increases hit cache - Fault isolation Y-axis - More secured Cons: - Difficult and time consuming X-axis 12
Scaling Applications : Z - AXIS Split Similar Things - Separates by region, customers Infinit ite Scale - Separates into resources Pros : - Increases hit cache - Fault isolation Y-axis - More secured Cons: - Difficult and time consuming X-axis 13
Is it sufficient to scale using one axis? - Coupled with the needs of an organization - They might be all used and mixed AKF Scale Cube - https://akfpartners.com/growth-blog/scale- cube, 9/21/2019 14
04 Practical Use of AKF Scale Cube 15
Airline Reservation System Airlines reservation system developed by IBM, consists of the below: 1- Original/Destination duals and inventories. 2- Global distributed system GDS, connect providers with travel agencies. 3- Real time dynamic pricing system, based on varied number of flight or search characteristics. 16

Conclusion 18
Conclusion AKF Scale Cube can be used to scale either organizations or applications. ● The AKF Scale Cube shows how we can scale but doesn’t say exactly when or which axis should be ● applied. It’s up to its users to define their needs and decide which strategies should be followed. ● Whenever you need to scale think AKF Scale Cube. ● 19
