2. DataPower Gateways can deploy anywhere…
Physical appliances: All-in-one (HW / SW), DMZ-ready with physical security including crypto acceleration and
optional hardware security module (HSM)
Software: virtual appliance, application (Linux) & container (Docker) provide flexible deployment options for both
cloud and on-prem environments

3. Choosing the right Gateway form factor
Physical appliances provides the most
comprehensive security combined physical
with firmware security.
Virtual, Linux and Container offer “right
sized” units of capacity, as few as 4 CPUs
Container provide ability to leverage auto-
scaling and runtime health monitoring
Container is “cloud ready” to facilitate both
public and private cloud based deployments

4. Natively built API Gateway using
purpose-built technology for native
OpenAPI/Swagger REST and SOAP APIs
Multi-cloud scalability and extensibility
to help meet SLAs and improve client
user experience
IDG X2 physical appliances use the
equivalent of 48 vCPU
Single API Gateway supports 30K TPS with 8 ms latency!

Each Benchmark API Assembly includes:
• Rate-limit
• Activity-log
• Client-id validation
Each Benchmark APIs runs with
• 4KB request payload
• Running on IDGX2 and 8 vCPU virtual gateways

7. Single gateway service used for
comparative analysis across three
gateway types:
• API Gateway
• V2018 Multi-protocol Gateway (v5c)
• V5 Multi-protocol Gateway
Backend service simulator is a “no-op”
that delays response using random
uniform distribution between 45 mS and
55 mS
