Projects
AWS Cloud:
• Migrating legacy IPICS appl. to AWS : Due to hard coded DHCP option for the legacy appl. and AWS requirement to disable static IP address assignment, the legacy product was partially migrated on AWS and thus Kubernetes based approach was adopted to make it cloud friendly.
• Hosting a website on AWS as redundant and fault tolerant using multi region architecture (using CloudFront, ELB, Route53 Latency Routing Policy, EC2, and RDS).Site hosted in two regions, to avoid outage for customers in case so if one region being affected.
• Hosting a static html website on S3 and point the S3 bucket endpoint to a domain name using Route53.
• Using Lambda function to stop the EC2 instance on a scheduled time.
• Deploying Elastic File System (EFS) on Linux based EC2 instances.
Automation:
• Deployed Automation solution for Puppet on UCS servers using Puppet Agent and Master.
• Successfully tested installation of different repositories. Currently working on manifests creation for installing Cisco Call Manger.
Kubernetes and SIP Bridge integration:
• With nodes and container failure possibility of SIP Bridge, when integrated with ICE for establishing SIP calling one has to ensure if multiple nodes can be integrated with single ICE K8s cluster and work as an integral part.
• Integration of multiple SIP bridge was successful ensuring high availability/scalability and call handling capacity.
UCCX Installation:
- Deployed a fresh setup of Cisco UCCX with Finesse desktop client.
- Worked on scope of development for UCCX and legacy Instant Connect application for providing solution for using prompts for DIal-Engine functionality(Users can join the channel by dialing in the UCCX trigger and as per steps guided by IVR)
Jabber for Windows in Phone-Only Mode :
- Jabber was successfully integrated with CUCM by avoiding additional IM and Presence integration.
