12. What is the issue with current deployments

13. Issues with current deployments
1. Lack of services separation – common middleware
2. Monolithic big application
3. Heavy regression testing because of inter-service dependency
4. Complicated deployment procedure which differs depend on test, pre-
prod, prod environment
5. Heavy acceptance tests – version rollout
6. No or limited automatic scalability – peak support

18. Evolution not revolution

19. What is our proposal?
We believe in evolution instead revolution
• Step by step approach.
1. 2018-2019 – utilize existing
JainSLEE/SIPServlets platforms
and optimize the cost structure
for new services
2. 2019 – 2021 – hybrid deployment
mixing legacy and cloud native
services
3. 2021+ - Unified cloud native
deployment
OVOO company confidential 19
• HOW TO?
– Application Server based
service should be migrated to
cloud native apps
– Decoupling based on micro
services
– Containers for automated
deployment and DevOps
– Container orchestration for
scalability and management

20. Service Broker – Orchestration
20
• Horizontal
orchestration
– Business level
orchestration
– SIP and Call Control REST
– Stateful balancing
– Profile based
• Legacy and new services
orchestration
– Based on the profile the
SB can orchestrate
between new cloud based
apps and legacy JainSLEE
services
– The IMS and CS core can
trigger directly legacy SDP
platform or use SB

25. Results

26. 26
OCS and MSGGW deployment
• Project was successfully
accomplished in
September/2018.
• Since that time, the OCS is
working without any down time
• Last time we added MSG GW to
the solution (replaced legacy
one)
• The system is handling in
average 1000 TPS with pick up
to 2000 TPS
• The Average latency is 20
milliseconds

32. Lessons learned
• Yes - you can do it.
• Yes – it works for real time services
• Is “platform” still needed?
– You don’t need platform you need the way to control the
environment
• Be aware – automatization is very cool but the first
deployment require a lot of work.
• You have to be ready for a quick deployment and
scalability
