Planning & Implementing biggest Hybrid Cloud in Bangladesh (pacecloud.com) using Cisco Cloud Center as Cloud orchestration, Cisco ACI as SDN and Cisco hyperflex as Hyper-converged
infrastructure with VMware as the main Hypervisor and Kubernetes as the container platform. We used F5 LTM, GSLB for ADC feature for our Hybrid Cloud with WAF & Anti-DDoS. We used Commvault for Backup as Service to our cloud customers. Also we have implemented
Multi-cloud feature of Cisco Cloud Center to allow our customer deploy Apps service in all major
Public Cloud (AWS, GCP, Azure).
