Beyond POLB(Plain Old Load Balancing)

Scalability is how we maintain performance and availability

POLB(Plain Old Load Balancing)

How do we scale OUT today?

POLB (Plain Old Load Balancing)• Born in the mid 1990s• Distributes load based on network variables • Focused on algorithms, not architecture

Traffic goes in Traffic goes out

But architectures and apps are changing

THENMONOLITHIC MICROSERVICES & APIs

NOW

And so are “users”

NOWHumans, Systems, Things
