Key Challenges

How to Scale ?– Need for quick ramp up in

capacity – Cloud & Physical Backend

  How to work with fixed capacity ?– Fixed capacity on DB or

backend  What to do when peak load is

unlimited ?– No way to control overload vs. capacity

Why LoadTest Cloud

Planning proactive cloud scaling– A capacity test provides the metrics to identify

the infrastructures limits

– Cloud application managers can act proactively

before performance is degraded

Actual capacity of adding new servers – Doubling server capacity doesn’t mean the

application can handle double the load.

– Capacity testing shows what the new user capacity is.

Test failover procedures – During peak loads and in multi-tenancy

environments– “Work out the kinks” of their failover procedures

before they really need it.

Dynamic Queing

All applications have a maximum load level– Load start page

– Deliver dynamic content

– Database transactions

Exceeding limits typically lead to a crash

Key Features Unlimited Capacity – designed to handle the largest possible

unexpected event loads, beyond 100,000 concurrent users per minute

Flexible subscription – ready to take over on a moments notice, or use it 24/7/365 ongoing operation

Dynamic Queuing Management – reroutes excess users to “wait page”; reroutes queued users to a separate network

Real Time Monitoring – displays user response times and application performance

Easy Setup – can by used by any website or service regardless of its host location or ISP.
